Description

  The present invention relates to a DVD recorder and a moving image reproducing apparatus for reproducing a moving image signal from a recording medium on which a moving image signal is recorded. More specifically, the present invention is extracted from a video unit of a moving image signal recorded on a recording medium. The present invention relates to a DVD recorder and a moving image playback apparatus for displaying still images as thumbnails.

  In a device that enables recording and reproduction of a moving image signal using a DVD as a recording medium, that is, a DVD recorder, a still image is displayed as a thumbnail so that the recorded contents of the DVD to be reproduced can be easily known. Function is provided. Therefore, when a title key which is a key for inputting a thumbnail display instruction is operated, one still image is extracted from each recorded title, and the extracted still image is displayed as a thumbnail. (This is the first prior art).

  Further, the following technique has been proposed (referred to as a second conventional technique). That is, in this technique, when a commercial broadcast is received and recorded, the commercial start time and end time are detected. Then, after the commercial is finished, an image when a predetermined time such as 1 second elapses or an image immediately before the transition to the commercial is used as a thumbnail image representative of the title recorded at that time. As a result, the thumbnail image shows the contents of the recorded title better (see, for example, Patent Document 1).

  Further, the following technique has been proposed (referred to as a third conventional technique). That is, in this technique, a scene change is detected, and an image when the scene changes is extracted as a thumbnail image. In addition, among the thumbnail images extracted in this way, the thumbnail image belonging to the front 15 seconds and the thumbnail image belonging to the rear 15 seconds of the reproduction position at that time are in a band-like range extending in the horizontal direction of the screen. it's shown. Therefore, the extracted thumbnail image is displayed so as to flow from the right side to the left side in the band-like range.

  However, in the display method described above, if the scene continues for a short time, the thumbnail images are displayed in an overlapping manner, making it difficult to see the thumbnail images. If one scene is too long, the time interval for extracting thumbnail images becomes too long, and a situation in which thumbnail images are not displayed occurs. For this reason, extraction of one thumbnail image is stopped for a thumbnail image to be extracted within 5 seconds. Further, when the scene does not change even after 15 seconds have elapsed, the image when 15 seconds have elapsed has been extracted as a thumbnail image (see, for example, Patent Document 2).

Further, the following technique has been proposed (fourth conventional technique). That is, in this technique, thumbnail images are displayed as animations. At the time of recording a program, feature points characterizing the contents of the title or scene (feature points of image data displaying a human face, telop, etc.) are detected, and position information of the feature points is recorded. Further, a scene change point is detected and its position information is recorded. When displaying thumbnail images, based on the positional information of the feature points and scene change points, three screens that are separated from each other by five fields are extracted from each scene, and the extracted three screens indicate each scene. Animation is displayed as a thumbnail image. At this time, the thumbnail images are selected so that the three screens separated from each other by five fields do not cross the scene change point. For this reason, for example, when a scene change point comes between the second screen and the third screen, the thumbnail image is composed of two screens. When a scene change point comes immediately behind the representative screen, three screens are selected in the forward direction at intervals of 5 fields from the representative screen (see, for example, Patent Document 3).
JP 2003-274361 A JP 2001-218164 A (paragraphs 0071-0088) JP 2001-298711 A (paragraphs 0062-0073)

  However, when the first prior art is used, the following problems have occurred. That is, when performing thumbnail display, by default, an image at the time when recording is started is extracted as a still image for thumbnail display. For this reason, an image extracted as a still image is often a commercial image or a scene change. As a result, it becomes difficult to recall the recorded contents from the still image displayed as a thumbnail, and the thumbnail display becomes meaningless. On the other hand, in order to avoid such a situation, a model having an editing function capable of designating the extraction position of a still image used for thumbnail display as a recording position where a user's favorite image is recorded is also provided. However, in order to use this function, it is necessary to learn a complicated operation procedure. For this reason, there is a demand for an apparatus that enables thumbnail display that shows the recorded contents better by a simple operation.

  The second conventional technique is a technique that uses, as a thumbnail image, an image when a time such as 1 second elapses after the commercial ends or an image immediately before the commercial. For this reason, a means for detecting the recording position of the commercial is required, resulting in complication of the apparatus. In addition, since it is difficult to improve the detection accuracy of the recording position of commercials, in many cases, the image when 1 second etc. has passed after the end of the commercial or the image immediately before the commercial was actually recorded. In a program, an image that has passed 1 second after the end of the commercial or an image immediately before the commercial is not obtained. For this reason, there are many situations in which the thumbnail image does not become an image showing the recorded content well.

  In the third conventional technique, among the extracted thumbnail images, a thumbnail image belonging to the front 15 seconds of the reproduction position and a thumbnail image belonging to the rear 15 seconds are strip-shaped extending in the horizontal direction of the screen. It is a technology premised on displaying within the range. For this reason, in the case of a configuration in which the extracted still image is displayed as a thumbnail at a preset position, it is difficult to apply the configuration because the underlying configuration is different.

  The fourth prior art is a technique premised on displaying thumbnail images as animations. For this reason, in the case of a configuration in which the extracted still image is displayed as a thumbnail at a preset position, it is difficult to apply the configuration because the underlying configuration is different.

The present invention was devised to solve the above-described problems, and the purpose of the present invention is to record a video by simply inputting a simple operation without editing the extraction position of a still image displayed as a thumbnail. Still images can be displayed as thumbnails, and the number of operations input when displaying still images as thumbnails for easy understanding of recorded contents can be reduced. Provides a DVD recorder that can make a still image displayed as a thumbnail first a still image that makes it easy to grasp the recorded content when performing thumbnail display again using a DVD that has finished displaying thumbnails. There is to do. 1
It is another object of the present invention to move a still image extraction position by a predetermined time when an instruction to change thumbnail display is input in a state in which still images are displayed as thumbnails, thereby displaying still images displayed as thumbnails. It is an object of the present invention to provide a moving image playback apparatus capable of displaying still images as thumbnails by simply inputting a simple operation without editing image extraction positions and facilitating the understanding of recorded contents.

  In addition to the above purpose, when an instruction to change thumbnail display is input in a state where a plurality of still images are displayed as thumbnails, the extraction positions of all the still images displayed in thumbnails are moved by a predetermined time. Accordingly, it is an object of the present invention to provide a moving image reproducing apparatus capable of reducing the number of operations input when displaying still images as thumbnails for easy understanding of recorded contents.

  In addition to the above-described purpose, when an instruction for changing the thumbnail display is input in a state where a plurality of still images are displayed as thumbnails, one each of the still images is input each time an instruction for changing the thumbnail display is input. A moving image reproducing apparatus that can easily confirm a still image whose display has been changed among a plurality of still images displayed as thumbnails by moving the extraction position by a predetermined time. There is.

  In addition to the above purpose, by enabling the user to select a still image whose extraction position is to be changed, it is possible to change only a still image corresponding to a title whose recording content is difficult to grasp and to display a thumbnail display. To provide an apparatus.

  In addition to the above purpose, when the thumbnail display ends, the thumbnail image is displayed again by recording the extraction position of the still image displayed in the thumbnail on the recording medium. An object of the present invention is to provide a moving image reproducing apparatus capable of making a still image displayed as a thumbnail first as a still image that makes it easy to grasp the recorded contents when displaying.

In order to solve the above problems, a DVD recorder according to the present invention records a moving image signal on a DVD, reproduces the moving image signal recorded on the DVD, displays it on the display unit, and records it on the DVD. A video image signal segmented for each title in each video image signal is defined as one video unit, and a still image at an extraction position designated for each video unit is extracted and set in advance in the display unit.

When the thumbnail display change key of the input unit is operated, the positions respectively displaced backward in the recording direction for a predetermined time from the extraction positions of the still images in the thumbnail display for all video units are displayed. change the extracted position indicated, and the front from the extraction position of each still image in the thumbnail display at that time every time the key for thumbnail display change is operated Extraction position indicating means for repeating the process of instructing by changing each position displaced backward in the recording direction for a predetermined time to each extraction position, and each extraction position of each video unit is instructed from the extraction position indicating means Sometimes, the main processing means is controlled to extract the still image at each designated extraction position and display it as a thumbnail in each predetermined display area, and a still image is displayed in each display area of the display unit. When the extraction position to be changed is instructed from the extraction position instruction means in the state of being displayed, all the still images being displayed are changed to the still images at the newly instructed extraction positions almost simultaneously. Thumbnail display means for controlling the main processing means;
Prior to causing the main processing means to control playback of a DVD when there is an input for selecting playback from the still image displayed on the thumbnail from the input unit, When the control function for controlling the main processing means so as to record the extraction position of each still image currently displayed in the thumbnail on the DVD and the command for changing the predetermined time are input from the input unit, the predetermined time And an initial setting function for changing and setting to a predetermined time .

In order to solve the above-described problem, a moving image reproducing apparatus according to the present invention reproduces a moving image signal recorded on a recording medium and displays it on a display unit, and for each title in the moving image signal recorded on the recording medium. A video image signal segmented into a video unit is taken as one video unit, a still image at an extraction position designated for each video unit is extracted, assigned to each preset display area in the display unit, and thumbnails Main processing means for generating and outputting a video signal for display, an input unit for inputting a command corresponding to the operation key when various keys are manually operated, and a moving image based on the input command from the input unit and a control unit which controls the entire system of the reproducing apparatus, the control section, when the thumbnail display keys of the input unit is operated, a recording medium set It is determined whether or not the extraction position of the still image is recorded, and when the determination result is recorded, the extraction position recorded for each title is indicated, while when the determination result is not recorded, The start position of each video signal in each video unit is designated as an extraction position, and the thumbnail display change key of the input unit is operated in the state where still images are displayed as thumbnails in the display areas of the display unit. A position that is displaced from the extraction position of the still image in the thumbnail display in the recording direction to the rear in the recording direction is changed to the extraction position, and the thumbnail display change key of the input unit is displayed. instructs but by changing the position displaced by the recording direction of the rear predetermined time from the extraction position of the still images in the thumbnail display at the time each time it is operated on the extracted position An extraction position instruction unit that repeats the process, and each time an extraction position of each video unit is instructed from the extraction position instruction unit, a still image at each extraction position is extracted and displayed as a thumbnail in a predetermined display area. The main processing means is controlled at the same time, and each time an extraction position to be changed is instructed from the extraction position instruction means in a state where a still image is displayed in each display area of the display unit, And a thumbnail display means for controlling the main processing means so that the still image at the newly designated extraction position is changed to be displayed.

Further, in the moving image playback apparatus, in addition to the above configuration, the extraction position instruction means operates the thumbnail display change key of the input unit in a state where still images are displayed as thumbnails in the display areas of the display unit. The position shifted backward in the recording direction for a predetermined time from the extraction position of the still image displayed in the thumbnail for all video units is designated as the extraction position, and the input unit Each time the thumbnail display change key is operated, there is a function for instructing by changing the position displaced from the extraction position of all the still images currently displayed in the thumbnail to the rear in the recording direction for the predetermined time to the extraction position. The thumbnail display means changes from the extraction position instruction means in a state where still images are displayed in the display areas of the display unit. Each time the extraction position is designated, the main processing means is controlled so that all the still images being displayed are changed to the still images at the newly designated extraction positions almost simultaneously. Preferably it is.

Further, in the moving image playback apparatus, in addition to the above configuration, the extraction position instruction means may include a thumbnail display change key of the input unit in a state where still images are displayed as thumbnails in the display areas of the display unit. When the operation is performed, only the first video unit is instructed by changing the position displaced backward in the recording direction from the extraction position of the still image displayed in the thumbnail for a predetermined time to the extraction position, Thereafter, each time the thumbnail display change key of the input unit is operated , the video unit whose position is to be changed is sequentially changed from the second to the last one by one, and the changed video unit is designated. Only the position where the still image is being displayed in the thumbnail display position is shifted to the extraction position after the predetermined time is changed to the extraction position . Each time the thumbnail display change key is operated , the thumbnail display means has a function of sequentially changing the video unit whose position is to be changed from the last to the first and sequentially changing the video unit one by one and repeating the same control process. The extraction is newly instructed only for the display area corresponding to the video unit instructed to change the extraction position from the extraction position instruction means among the still images being displayed in each display area of the display unit. The main processing means may be controlled to change and display a still image of the position.

Further, in the moving image reproduction device, the control unit may further select one of the still images being displayed in each display area of the display unit and select and input the operation by operating the input unit. The image selection means for selecting the display area where the designated still image is displayed and instructing the extraction position instruction means. The extraction position instruction means includes a still image in each display area of the display unit. When the thumbnail display change key of the input unit is operated in the state where each thumbnail is displayed, only the video unit corresponding to the display area instructed from the image selection unit is previously stored from the extraction position of the still image displayed in the thumbnail display. change the set displaced position by the recording direction of the rear predetermined time extraction position indicated, and thumbnail display changing keys of the input unit Misao Function of instructing to change the extraction position of the still image thumbnails being displayed on the display area instructed from the image selection means at that time every time it is the extraction position position displaced to only the recording rearward the predetermined time And the thumbnail display means when the extraction position to be changed is instructed from the extraction position instruction means in a state where still images are respectively displayed in the display areas of the display section. The main processing means may be controlled so that only the still image being displayed in the display area instructed from is changed to a still image at the newly designated extraction position and displayed.

In the configuration having the image selection means, the control unit may display the cursor by operating the cursor movement key of the input unit in a state where a still image is displayed in each display area of the display unit. A control function for controlling the main processing means to identify and display the display area where the cursor is located so that it can be distinguished from other display areas when moved to any of the areas; selecting means, when the key for thumbnail display change of the input unit is operated, it is adapted to instruct the extraction position indicating means selects a display area that is the identification.

On the other hand, in the configuration having the image selection means, each display area of the display unit is configured to display a unique numerical value at each corner of the area when displaying a still image,

The image selection means may be configured to select a display area displaying a unique numerical value that matches a numerical value input by operating a numeric key of the input unit and instruct the extraction position instruction means. .

Further, in the moving image reproducing apparatus, the control unit further includes the main processing unit when there is an input for selecting one of the still images displayed in the thumbnail and instructing reproduction from the input unit. Before the control to reproduce the recording medium by the control function for controlling the main processing means to record the extraction position of each still image currently displayed in the thumbnail on the recording medium, and the input unit It is preferable to have an initial setting function that changes and sets the predetermined time to the commanded predetermined time when a command to change the predetermined time is input .

According to the DVD recorder of the first aspect, the still image of each title is displayed as a thumbnail in each display area of the display unit simply by operating the thumbnail display key, and the still image displayed as a thumbnail is viewed. When the recorded content of the title cannot be sufficiently grasped from the still image, the thumbnail image displayed in all the display areas can be displayed by simply operating the thumbnail display change key of the input unit once. Since the display is changed all at once, the still image indicating the recorded content of the desired title can be changed and displayed by one-touch operation of a specific key without specifying the title to be reproduced and without editing the extraction position . The number of operations is reduced. In addition, if the recorded content of the target title cannot be grasped sufficiently even after viewing the changed still image, the thumbnail display is changed until a still image that can sufficiently grasp the recorded content of the title is displayed as a thumbnail. Just repeat the key operation. In this way, it is only necessary to continue to operate the same thumbnail display change key while viewing and checking each still image that is sequentially changed and displayed on the display unit, so there is no need to learn complicated operation procedures and Is extremely simple.

In addition, when the user feels that an effective still image that can grasp the recorded contents is not effectively changed and displayed when the thumbnail display change key is operated, a predetermined time for shifting from the still image extraction position in the thumbnail display is set. By performing an initial setting that is arbitrarily changed, a desired still image can be quickly displayed as a thumbnail, and in this respect also, editing of the extraction position of the still image is not required. Furthermore, when the thumbnail display ends , that is, when a desired one of the still images displayed in the thumbnail display is selected and playback is instructed, each still image displayed in the thumbnail at that time, that is, the recorded content by the user Since the still image extraction position whose display has been changed so as to be sufficiently grasped is automatically recorded on the DVD , the user can record it only by operating the thumbnail display key when the DVD is next played. Since a still image whose contents can be sufficiently grasped is immediately displayed as a thumbnail, it is not necessary to edit a desired still image extraction position. Further, when the thumbnail display change key is operated, the position displaced backward in the recording direction for a predetermined time from the extraction position of the still image in the thumbnail display is changed to the extraction position. Does not require editing of the still image extraction position. Further, since the various functions described above can be obtained mainly by changing or adding a software program of the control unit of an existing DVD recorder, the configuration is not complicated and the cost is not increased.

According to the moving image reproducing apparatus of the second aspect of the present invention, when a still image displayed as a thumbnail in each display area of the display unit is viewed, the recorded content of the title cannot be sufficiently grasped from the still image. By just operating the thumbnail display change key in the input section once, the still image displayed as a thumbnail is displayed in the display area, and the recorded content of the target title is still displayed even when the displayed still image is viewed. If it is not possible to grasp sufficiently, it is only necessary to repeat the operation of the thumbnail display change key until a still image capable of sufficiently grasping the recorded content of the title is displayed as a thumbnail . Since it is possible to sequentially display changes the still image showing the recorded contents of a desired title by one-touch operation of a single key, and it requires only a number of times of the operation rather small, by sequentially changing the display unit Since it is only necessary to continue to operate the same thumbnail display change key while viewing and confirming each displayed still image, it is not necessary to learn a complicated operation procedure, which makes the operation extremely simple. Further, when the thumbnail display change key is operated, a position displaced backward in the recording direction for a predetermined time from the extraction position of the still image in the thumbnail display is changed to the extraction position. There is no need to edit the extraction position. In addition, since the various functions described above can be obtained mainly by changing or adding a software program of the control unit of the existing moving image playback device, the configuration is not complicated and the cost is not increased.

According to the moving image reproducing apparatus of the invention according to claim 3, when the recorded content of the title cannot be sufficiently grasped from the still image displayed as a thumbnail in each display area of the display unit, the thumbnail display change key of the input unit the only one operation, since the still image is thumbnail displayed in all display areas are displayed changed together, there is no need to specify a title to be reproduced, one-touch operation of a single key Can quickly change and display a still image indicating the recorded content of the desired title, and if the recorded content of the target title cannot be sufficiently grasped even after viewing the displayed still image, the title Since it is only necessary to repeat the operation of a single key until a still image that can sufficiently grasp the recorded content is displayed as a thumbnail, the number of operations is reduced. Can be rapidly thumbnail valid still image corresponding to a title of interest, the operation also becomes extremely easy.

According to the moving image reproducing device of the invention according to claim 4, when the recorded content of the title cannot be sufficiently grasped from each still image displayed as a thumbnail in each display area of the display unit, for changing the thumbnail display of the input unit When the key is operated, the still image of each display area is sequentially displayed and changed from the first display area to the last display area for each operation. This confirmation can be performed by a simple operation in which the same key operation is repeated as many times as necessary, and it is not necessary to designate a target title. Therefore, the operation can be performed easily and quickly.

According to the moving image reproducing device of the invention according to claim 5, when each still image displayed as a thumbnail in each display area of the display unit is viewed, only one or a plurality of specific still images are displayed. If the recorded content of the title cannot be sufficiently grasped, a specific still image is displayed when a specific still image is specified by operating the input section and then the thumbnail display change key of the input section is operated. Only a specific display area is changed to another still image. If you can't fully grasp the recorded contents even after viewing the changed still image, further operation of the thumbnail display change key will change only the still image in the specific display area for each operation. Therefore, it is only necessary to continue the operation of the same key until a still image capable of sufficiently grasping the recorded contents is displayed as a thumbnail. In this case, the first still image can fully understand the recorded contents of the thumbnail displayed still image, since it is held without being displayed change, the recorded contents of all the still images Ru Tei displays thumbnails The display can be quickly changed to a still image that can be reliably grasped.

According to the moving image reproducing apparatus of the invention of claim 6, as a specific configuration of the invention of claim 5, the cursor is moved to a specific display area by operating an existing cursor movement key provided in the input unit. When moved, the specific display area is identified and displayed so that it can be distinguished from other display areas, so that the user can surely visually recognize the specific display area designated by the user by the identification display on the display unit, In this state, it is only necessary to confirm a still image in a specific display area whose display is changed each time the thumbnail display change key is operated. In addition, this configuration has an advantage that selection of a specific display area can be achieved at low cost only by changing the software program of the control unit.

According to the moving image reproducing device of the invention of claim 7, as another specific configuration of the invention of claim 5, each display area is unique to each corner of each display area when a still image is displayed. The number keys are the same as the display numbers in the display area where thumbnails are displayed for still images whose recorded contents cannot be fully grasped by looking at the display numbers on the display unit. After that, it is only necessary to continue to operate the thumbnail display change key until a still image capable of sufficiently grasping the recorded contents is displayed as a thumbnail.

According to the moving image playback device of the invention of claim 8, when the user feels that an effective still image capable of grasping the recorded content is not effectively changed and displayed when the thumbnail display change key is operated , the thumbnail display is performed. By performing an initial setting to arbitrarily change the predetermined time to be displaced from the still image extraction position in the middle, it is possible to quickly display the desired still image as a thumbnail, and in this respect also edit the extraction position of the still image do not need. Furthermore, when the thumbnail display ends , that is, when a desired one of the still images displayed in the thumbnail display is selected and playback is instructed, each still image displayed in the thumbnail at that time, that is, the recorded content by the user Since the still image extraction position whose display has been changed so as to be sufficiently grasped is automatically recorded on the DVD , the user can record it only by operating the thumbnail display key when the DVD is next played. Since a still image whose contents can be sufficiently grasped is immediately displayed as a thumbnail, it is not necessary to edit a desired still image extraction position. Further, when a display change instruction is input, the position displaced backward in the recording direction for a predetermined time from the extraction position of the still image in the thumbnail display is changed as the extraction position. There is no need to edit the extraction position of the still image. In addition, since the various functions described above can be obtained mainly by changing or adding a software program of a control unit of an existing moving image playback device, the configuration is not complicated and expensive.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram showing an electrical configuration of the first embodiment of the moving picture reproducing apparatus according to the present invention, and specifically shows a DVD recorder.

  In the figure, a tuner unit 1 receives a commercial broadcast of a channel designated by the microcomputer 7 and outputs an analog video signal (including an analog audio signal) obtained by reception to the A / D conversion unit 2. . The A / D conversion unit 2 converts the analog video signal output from the tuner unit 1 into a digital video signal (hereinafter referred to as a moving image video signal) and outputs it to the signal processing unit 3.

  The disk drive unit 5 performs processing such as encoding on a digital signal output from the signal processing unit 3 (a signal including a moving image signal, an audio signal, and the like, hereinafter referred to as a moving image signal). The obtained signal is recorded on a DVD (a recording medium according to claims, specifically, a DVD-RW, a DVD + RW, or the like) 11. In addition, after reading a digital signal (a signal including a moving image signal, an audio signal, etc., which is referred to as a moving image signal) recorded on the DVD 11 and performing processing such as demodulation and error correction, a signal processing unit 3 is output.

  The D / A converter 4 converts a digital video signal (a signal including a digital audio signal, hereinafter referred to as a moving image video signal) output from the signal processing unit 3 into an analog video signal (including an analog audio signal). It converts and outputs to the television receiver 6 provided outside.

  The signal processing unit 3 uses the encoding unit 14 to compress the video signal output from the A / D conversion unit 2 in accordance with the MPEG2 standard, and outputs it to the disk drive unit 5. Further, by using the decoding unit 15, the moving image signal output from the disk drive unit 5 is expanded according to the MPEG2 standard. Then, the moving image video signal (digital video signal) obtained by the decompression process is output to the D / A converter 4.

  Further, the signal processing unit 3 extracts a still image designated by the microcomputer 7 from the moving image video signal output from the disk drive unit 5. Further, an on-screen display unit (hereinafter referred to as an OSD unit) 16 is used to generate a video signal for displaying the extracted still image as a thumbnail and output it to the D / A conversion unit 4 (claims). The main processing means 10 includes a disk drive unit 5 and a signal processing unit 3).

  The input circuit unit 8 includes a key switch such as a power key provided on the front panel of the apparatus main body (not shown), a light receiving unit that receives an infrared signal transmitted from the remote controller 9, and the like (instructions from the user) For example, an operation for instructing a change of a still image displayed as a thumbnail is input. Further, the input instruction from the user is output to the microcomputer 7.

  The microcomputer 7 controls main operations as a moving image reproducing apparatus. That is, the channel received by the tuner unit 1 is controlled in accordance with a user instruction input to the remote controller 9 or the like. Further, by controlling the disk drive unit 5 and the signal processing unit 3, the program (moving image signal) received by the tuner unit 1 is recorded on the DVD 11. Further, the moving image video signal recorded on the DVD 11 is reproduced and output to the television receiver 6.

  The extraction position instruction means 17 (configured by a part of the function of the microcomputer 7) displays a moving image signal (moving image) corresponding to each title when displaying a thumbnail of a still image indicating the recorded contents of each title. The thumbnail display means 18 is instructed of the extraction position when a still image is extracted from the video unit of the signal. In addition, when the extraction position of each still image at the end of the previous thumbnail display is recorded on the DVD 11, the thumbnail display means 18 is instructed on the extraction position recorded on the DVD 11. If the still image extraction position is not recorded on the DVD 11, the thumbnail display means 18 is instructed as the extraction position of the moving image signal corresponding to each title.

  The thumbnail display means 18 (configured by a part of the function of the microcomputer 7) extracts the still image at the extraction position designated by the extraction position instruction means 17 by controlling the main processing means 10. Then, the extracted still image is displayed as a thumbnail in an area on the screen set in advance corresponding to the video unit of the video signal.

  That is, with reference to FIG. 3 and FIG. 4, for example, the still image P11 extracted from the moving image video signal T1 of the title recorded at the head is the upper half of the left side of the screen of the television receiver 6. The still image P21 displayed in the area A1 and extracted from the moving image video signal T2 of the second recorded title is displayed in the area A2 on the right side of the still image P11. Further, the still image P31 extracted from the moving image video signal T3 of the third recorded title is displayed in the lower half area A3 of the screen 6.

  Returning to the description of the extraction position instruction means 17, the extraction position instruction means 17 receives a display change instruction for instructing a change in thumbnail display in a state where still images are displayed as thumbnails, to the remote controller 9. For all the still images displayed as thumbnails, the indicated extraction position is moved backward from the previous extraction position by a predetermined time (indicated by n in FIG. 3).

  If a supplementary explanation is given here, the default value of the predetermined time n is set to 30 seconds (the user can change the predetermined time n as will be described later). . Further, a skip-up key is used to input a display change instruction. For this reason, when the skip-up key is operated in a state where still images indicating the recorded contents of the respective titles are displayed as thumbnails, the extraction position of the still image displayed as a thumbnail is displayed every 30 seconds every time the skip-up key is operated. It is designed to move backward.

  Further, when the thumbnail display ends, the microcomputer 7 controls the disk drive unit 5 and the signal processing unit 3 to write the still image extraction position displayed at the end of the thumbnail display onto the DVD 11.

  FIG. 2 is a flowchart showing the main operation of the embodiment when displaying still images as thumbnails. The operation of the embodiment will be described with reference to FIG.

  Prior to the description of the operation of the embodiment, the relationship between the moving image signal corresponding to each title and the extracted still image will be described with reference to FIG.

  In FIG. 3, T1 indicates a moving image video signal for one title recorded first, and T2 indicates a moving image video signal for one title recorded second. T3 indicates a moving image video signal for one title recorded third. Therefore, when the head position of the moving image video signal for each title is designated as the extraction position, the still image P11 located at the beginning t11 of T1 is extracted from the moving image signal T1. Further, a still image P21 located at the beginning t21 of T2 is extracted from the moving image video signal T2, and a still image P31 located at the beginning t31 of T3 is extracted from the moving image video signal T3. In the following description, it is assumed that the number of titles recorded on the DVD 11 is four.

  Returning to the description of the operation of the embodiment. When the title key (not shown) of the remote controller 9 is operated in a state where the DVD 11 is set in the disk drive unit 5 (step S1), the microcomputer 7 moves the still image extraction position to a predetermined position on the DVD 11. It is checked whether time information indicating is recorded (step S2). If the time information is not recorded, the extraction position instruction means 17 instructs the head positions t11, t21, t31,... Of the video image signals for the respective titles as the still image extraction positions (steps). S3, S4).

  The thumbnail display means 18 extracts still images P11, P21, P31, and P41 from the instructed extraction positions t11, t21, t31,... (Step S5), and displays the extracted still images as thumbnails (Step S6). . As a result, still images P11, P21, P31, and P41 shown in FIG. 4A are displayed as thumbnails on the television receiver 6. Thereafter, the operation shifts to a loop operation for checking whether the reproduction key is operated (step S7) and whether the skip-up key is operated (step S8).

  When the user can grasp the recorded contents of each title only by referring to the thumbnail display shown in FIG. 4A, the user selects the title to be reproduced and then operates the reproduction key. When the reproduction key is operated, the operation proceeds from step S7 to step S12. For this reason, the microcomputer 7 controls the disk drive unit 5 and the signal processing unit 3 so as to indicate time information indicating the extraction positions of the still images P11, P21, P31, and P41 (in this case, the titles of the respective titles). (Time information indicating head positions t11, t21, t31,...) Is written on the DVD 11 (the time information written at this time is referred to as information indicating the extraction position of the still image at the next thumbnail display of the still image). ).

  On the other hand, from the still images P11, P21, P31, and P41 shown in FIG. 4A, when it is difficult to grasp the recording contents of each title, the skip-up key is operated. When the skip-up key is operated, it is determined that the thumbnail display is changed, and the operation proceeds from step S8 to step S9. For this reason, the extraction position instruction means 17 moves the extraction positions for all still images backward by 30 seconds from the previous extraction positions t11, t21, t31,... (Extraction positions are t12, t22, t32). , ・). Thereafter, the operation proceeds to step S5, and a still image is extracted. Further, thumbnail display of the extracted still image is performed (step S6).

  In the thumbnail display in step S6, the still image P12 is extracted from the title T1. Further, a still image P22 is extracted from the title T2, and a still image P32 is extracted from the title T3. Therefore, the images displayed as thumbnails in step S6 are still images P12, P22, P32, and P42 shown in FIG. That is, all four still images are changed by operating the skip-up key only once.

  When the recorded contents of each title can be grasped by referring to the thumbnail display shown in FIG. 4B, the title to be reproduced is selected and the reproduction key is operated. When the reproduction key is operated, the operation proceeds from step S8 to step S12, and time information indicating the extraction positions t12, t22, t32,... Moved backward by 30 seconds from the head is recorded on the DVD 11. Then, playback is started.

  When the next thumbnail display is performed using the DVD 11 set at this time, it is determined in step S3 that the extraction position is recorded. Accordingly, the operation proceeds from step S3 to step S11. Accordingly, at this time, still images for thumbnail display are extracted from positions t12, t22, t32,... Moved backward from the top of each title by 30 seconds. As a result, at this time, the user can grasp the recorded contents of each title only by referring to the still image initially displayed as a thumbnail, and can easily select the title to be reproduced.

  In addition, even when the thumbnail display shown in FIG. 4B is performed, if the recorded content of each title is difficult to understand, the skip-up key is operated again. When the skip-up key is operated again, still images are extracted from the positions t13, t23, t33,... 30 seconds behind the respective extraction positions t12, t22, t32,. Are displayed as thumbnails. Thereafter, each time the skip-up key is operated, the still image extraction position for thumbnail display moves backward by 30 seconds.

  The second embodiment will be described below. The second embodiment is the same as the configuration shown in FIG. 1 when shown as a block diagram, and only the configuration of the extraction position instruction means 17 is different. Therefore, regarding the configuration, only the extraction position instruction means 17 will be described.

  The extraction position instruction means 17 instructs the thumbnail display means 18 to specify the extraction position when a still image is extracted from a moving picture video signal corresponding to each title when displaying a thumbnail of a still image indicating the recorded contents of each title. .

  When the skip-up key is operated in a state where a plurality of still images are displayed as thumbnails, the extraction position for one still image among the plurality of still images displayed as thumbnails is moved. Further, when the skip-up key is operated, each time the skip-up key is operated, the still image whose extraction position is to be moved is sequentially moved among the plurality of still images.

  That is, as shown in FIG. 5A, when the skip-up key is operated in a state where four still images P11, P21, P31, and P41 are displayed as thumbnails, the still image displayed in the area A1 is displayed. Only the extraction position is moved backward by 30 seconds (the extraction position moves from t11 to t12). For this reason, the still image P12 recorded at the extraction position t12 is displayed in the area A1, as shown in FIG. Thereafter, when the skip-up key is operated again, the still image displayed in the area A2 is changed (see FIG. 5C), and when the skip-up key is further operated, the still image displayed in the area A3 is changed. It is changed (see FIG. 5D).

  When the main operation of the second embodiment configured as described above is shown as a flowchart, the flowchart shown in FIG. When the operation is shown in the flowchart of FIG. 2, the difference from the first embodiment is only step S9.

  That is, since the operation has shifted to steps S1 to S6, it is assumed that the thumbnail image shown in FIG. The user operates the skip-up key because it is difficult to grasp the recorded contents of each title from the thumbnail display. When the skip-up key is operated, the operation proceeds from step S7, S8 to step S9.

  At step S9, the extraction position instruction means 17 moves the extraction position in the video image signal T1 for the first title from the previous position t11 to the position t12 that is 30 seconds behind the other extraction positions. t21, t31,... are not moved. As a result, when the process proceeds from step S9 to steps S5 and S6, as shown in FIG. 5B, the still image displayed in area A1 is changed from still image P11 to still image P12 (area The still images displayed on A2 to A4 are not changed).

  When the skip-up key is operated in a state where the still image shown in FIG. 5B is displayed as a thumbnail, the extraction position instruction means 17 changes the extraction position in the video image signal T2 from the position t21 so far. It is moved to the rear position t22 for 30 seconds, and the other extraction positions t12, t31,... Are not moved. As a result, when the process proceeds from step S9 to steps S5 and S6, as shown in FIG. 5C, the still image displayed in the area A2 is moved from the still image P21 extracted from the position t21 to the position t22. The extracted still image P22 is changed.

  When the skip-up key is operated in a state where the still image shown in FIG. 5C is displayed as a thumbnail, as shown in FIG. 5D, the still image displayed in the area A3 is changed to the still image P31. To the still image P32. Thereafter, each time the skip-up key is operated, the area where the still image is changed is area A4, area A1 (the still image extracted from the extraction position t13 is displayed), and area A2 (extracted from the extraction position t23). The displayed still image is displayed).

  FIG. 6 is a block diagram showing an electrical configuration of the third embodiment. In the third embodiment, when shown as a block diagram, an image selection unit is further added to the configuration shown in FIG. When compared with the first embodiment, only the configuration of the extraction position instruction means is different except for the image selection means. For this reason, blocks that can be regarded as the same as the configuration shown in FIG. 1 are given the reference numerals in FIG.

  As shown in FIG. 8A, when the still images P11, P21, P31, and P41 are displayed as thumbnails, the image selection means 19 displays a cursor (indicated by a broken line C1) so that the still image is displayed. The area A1 to A4 displayed as thumbnails indicates which area is selected.

  When the thumbnail display of the still image indicating the recorded contents of each title is displayed, the extraction position instructing means 20 displays the extraction position when extracting the still image from the moving image signals T1 to T3,. The means 18 is instructed.

  In addition, when the skip-up key is operated while still images are displayed as thumbnails, an area (by the image selection means 19 selected from the plurality of still images P11, P21, P31, P41 displayed as thumbnails) ( For example, the extraction position of the still image to be displayed in the area A2) is moved from the previous extraction position t21 to the extraction position t22 behind by 30 seconds. As a result, as shown in FIG. 8B, the still image displayed in the area A2 is changed from the still image P21 to the still image P22.

  That is, when the skip-up key is operated in a state where still images are displayed as thumbnails, the extraction position instruction unit 20 determines the extraction position of the still image displayed in the area where the cursor C1 is positioned at that time. Move to the position 30 seconds behind the previous extraction position. When the skip-up key is further operated, the still image extraction position is moved further to the rear position by 30 seconds.

  FIG. 7 is a flowchart showing main operations of the third embodiment. Note that steps that can be regarded as the same as the operations shown in FIG. 2 are given the same reference numerals as those in FIG. 2, and detailed descriptions thereof are omitted.

  It is assumed that the thumbnail image shown in FIG. 8A is displayed on the television receiver 6 because the operation has shifted to steps S1 to S6. The user moves the cursor C1 to the area A2 using four direction keys (not shown) because it is difficult to grasp the recorded contents of the title corresponding to the area A2 from the thumbnail display (step S21). , S22), it is assumed that the skip-up key is operated. At this time, the operation proceeds from step S8 to step S9.

  Then, at step S9, the extraction position instruction means 20 moves only the extraction position in the moving image signal T2 corresponding to the area A2 to the position t22 that is 30 seconds behind the previous position t21. As a result, when the process proceeds from step S9 to steps S5 and S6, as shown in FIG. 8B, the still image displayed in the area A2 is changed from the still image P21 to the still image P22. Then, when the skip-up key is operated in a state where the still image shown in FIG. 8B is displayed as a thumbnail, at this time, the still image extracted from the position t23 is displayed in the area A2 (other areas). The still images of A1, A3 and A4 are not changed).

  Thereafter, each time the skip-up key is operated, the still image extraction position in the moving image signal T2 is moved backward by 30 seconds. When the cursor C1 is moved to another area (for example, area A3) and the skip-up key is operated, each time the skip-up key is operated, the still image of the corresponding video image signal (for example, T3) is displayed. The extraction position is moved backward by 30 seconds.

  The fourth embodiment will be described below. Note that the fourth embodiment is the same as the configuration shown in FIG. 6 when shown as a block diagram, and only the configuration of the image selection means is different. Therefore, only the configuration of the image selection unit will be described.

  When a still image indicating the recorded content of the video image signal of each title is displayed as a thumbnail, a number is displayed in association with each of the areas A1 to A4 where the still image is displayed. For this reason, the image selection means 19 selects the area where the number that matches the input numerical value is displayed when the numerical value is input by the numeric key (not shown) of the remote controller 9, and the selection result is extracted. Inform the instruction means 20. When the skip-up key is operated, the extraction position instruction means 20 sets the extraction position of the still image displayed in the area notified from the image selection means 19 to the extraction position 30 seconds behind the previous extraction position. Move to.

  FIG. 9 is a flowchart showing the main operation of the fourth embodiment. Note that steps that can be regarded as the same as the operations shown in FIG. 2 are given the same reference numerals as those in FIG. 2, and detailed descriptions thereof are omitted.

  It is assumed that the thumbnail image shown in FIG. 10A is displayed on the television receiver 6 because the operation has shifted to steps S1 to S6. It is assumed that the user operates the number “3” key indicating the area A3 because it is difficult to grasp the recorded content of the title corresponding to the area A3 from the thumbnail display. At this time, since the operation proceeds to steps S31 and S32, the image selection means 19 notifies the extraction position instruction means 20 that the area A3 has been selected. Thereafter, when the skip-up key is operated, the operation proceeds from step S8 to step S9.

  In step S9, the extraction position instruction unit 20 sets the extraction position to be instructed only for the moving image signal T3 corresponding to the area A3 notified from the image selection unit 19 by 30 seconds from the previous position t31. To the position t32. As a result, when the process proceeds from step S9 to steps S5 and S6, as shown in FIG. 10B, the still image displayed in area A3 is changed from still image P31 to still image P32. Then, when the skip-up key is operated in a state where the still image shown in FIG. 10B is displayed as a thumbnail, at this time, the still image extracted from the position t33 is displayed in the area A3 (other areas). The still images of A1, A3 and A4 are not changed).

  Thereafter, each time the skip-up key is operated, the still image extraction position in the moving image signal T3 is moved backward by 30 seconds. In addition, when a different area (for example, area A2) is instructed by operating other numeric keys and then the skip-up key is operated, each time the skip-up key is operated, it is displayed in the corresponding area. The still image extraction position is moved backward by 30 seconds.

  In the first to fourth embodiments, when the skip-up key is operated, the amount of movement by which the extraction position is moved backward can be changed by the user in the initial setting (this is the case). The description of the procedure for the change is omitted). The change amount step is 15 seconds equal to the commercial reference length because the commercial reference length is 15 seconds. Therefore, the user can change the amount of movement of the extraction position from 30 seconds to 45 seconds or 60 seconds according to his / her preference.

  Note that the present invention is not limited to the above-described embodiment, and the case where the number of areas where still images are displayed is four has been described. However, other numbers, for example, six or eight are used. It can be similarly applied to.

  In addition, the case where the recording medium of the video signal is a DVD has been described, but the same applies to a configuration in which a memory element such as a flash memory is used as a recording medium or a configuration in which a hard disk drive is used as a recording medium Can be applied to.
