A removable memory card 110 is mounted in a card slot (not shown). A battery 109 is loaded in a battery folder (not shown).

  The projector 10 reads out image data (image file) taken by the electronic camera from the memory card 110 or the hard disk drive (HDD) 103, and projects a reproduced image based on the image data on the projector unit 6 or a liquid crystal display. Or display on the display 12. The projector 10 can project (or display) a reproduced image based on image data supplied from an external device via the external interface (I / F) 104 in addition to the image data stored in the projector 10. It is. The projector 10 further copies the reproduction data and saves it in the hard disk drive (HDD) 103, or creates and saves management information for the reproduction data.

  The CPU 101 reproduces information by the projector 10 by sending a control signal to each part of the projector 10 by performing a predetermined calculation using a signal input from each part of the projector 10 based on the control program. Control the operation. The control program is stored in a nonvolatile memory (not shown) in the CPU 101.

  The memory 102 is used as a working memory for the CPU 101. The operation member 11 includes a plurality of operation members including a main switch, a display device changeover switch, a source changeover switch, a cross key, and the like. The operation member 11 sends an operation signal corresponding to the operation content to the CPU 101.

  The memory card 110 is configured by a nonvolatile memory such as a flash memory. The memory card 110 can write, save, and read video data and audio data according to instructions from the CPU 101. A hard disk drive (HDD) 103 is a recording device having a larger capacity than the memory card 110. A hard disk drive (HDD) 103 can write, save, and read data such as video data and audio data according to instructions from the CPU 101.

  An external interface (I / F) 104 converts a video signal transmitted from an external device such as a video camera into image data, and sends the converted image data to the CPU 101. Also, the external interface (I / F) 104 converts a signal transmitted from the external device into audio data to be played back by the speaker 107, and sends the converted audio data to the CPU 101.

  The liquid crystal display 12 reproduces and displays information such as images and texts according to instructions from the CPU 101. The text information is an operating state of the projector 10, an operation menu, and the like. When the CPU 101 instructs the liquid crystal display 12 to perform reproduction display, reproduction data corresponding to the display resolution of the liquid crystal display 12 (eg, horizontal 320 × vertical 200 pixels) is generated using the image data, and the generated data is It is sent to the liquid crystal display 12. The stereo speaker 107 reproduces sound based on sound data output from the CPU 101.

  The battery 109 is constituted by a rechargeable secondary battery, and supplies power to each part in the projector 10. The power supply circuit 108 includes a charging circuit and a voltage detection circuit. The power supply circuit 108 converts the voltage of the battery 109 into a voltage required for each part in the projector 10, and in addition, when the voltage of the battery 109 is low and the remaining capacity is reduced, AC / The battery 109 is charged with a charging current supplied via the DC adapter 13.

  The proximity sensor 111 is arranged side by side with the opening on a surface of the housing of the projector 10 having the opening of the projector unit 6. The proximity sensor 111 includes an LED that emits infrared light and a photodiode that receives infrared light, and transmits a detection signal to the CPU 101 when the infrared light received is at a predetermined level or higher.

  When the housing of the projector 10 is placed with the opening surface of the projector unit 6 down, or when the opening surface is too close to another object such as a screen, infrared light emitted from the LED is emitted. Reflected by the mounting surface or object and received by the photodiode.

(Projector part)
The projector unit 6 reproduces and projects information such as images and texts according to instructions from the CPU 101. The projector unit 6 includes a projection lens 61, a liquid crystal panel 62, an LED light source 63, a projection control circuit 64, and a lens driving circuit 65. The projection control circuit 64 supplies a drive current to the LED light source 63 in accordance with a projection command output from the CPU 101. The LED light source 63 illuminates the liquid crystal panel 62 with brightness according to the supplied current.

  When the CPU 101 instructs the projector unit 6 to perform reproduction projection, reproduction data corresponding to the display resolution of the liquid crystal panel 62 (corresponding to the projection resolution of the projector unit 6, eg, 640 × 400 pixels) using the image data. And the generated data is sent to the projector unit 6. The projection control circuit 64 generates a liquid crystal panel drive signal in accordance with the reproduction data sent from the CPU 101, and drives the liquid crystal panel 62 with the generated drive signal. Specifically, a voltage corresponding to the reproduction data is applied to the liquid crystal layer for each pixel. In the liquid crystal layer to which a voltage is applied, the arrangement of liquid crystal molecules changes, and the light transmittance of the liquid crystal layer changes. In this manner, the liquid crystal panel 62 generates an optical image by modulating the light from the LED light source 63 according to the reproduction data.

  The projection lens 61 projects the light image emitted from the liquid crystal panel 62 onto a screen or the like. Based on the offset adjustment signal output from the projection control circuit 64, the lens driving circuit 65 drives the projection lens 61 to advance and retract in a direction orthogonal to the optical axis. Further, the lens driving circuit 65 drives the focus lens (not shown) constituting the projection lens 61 to advance and retreat in the optical axis direction based on the focus adjustment signal output from the projection control circuit 64. The lens driving circuit 65 further drives a zoom lens (not shown) constituting the projection lens 61 forward and backward in the optical axis direction based on the zoom adjustment signal output from the projection control circuit 64. The offset adjustment amount, the focus adjustment amount, and the zoom adjustment amount are instructed from the CPU 101 to the projection control circuit 64.

(Projected image offset)
By shifting the projection lens 61 in a direction perpendicular to the optical axis, the emission direction of the light beam emitted from the projector unit 6 changes, and the projection image is offset. In addition to shifting the projection lens 61, the projection image may be offset by shifting the liquid crystal panel 62 and the LED light source 63 in the direction perpendicular to the optical axis. That is, the offset of the projected image can be realized by changing the relative positional relationship between the projection lens 61 and the liquid crystal panel 62 in a direction perpendicular to the optical axis.

(Keystone correction of projected image)
When a part of the projection lens 61, the liquid crystal panel 62, and the LED light source 63 is shifted in a direction perpendicular to the optical axis, keystone correction is performed on the data to be projected according to the shift amount. Since the projection image changes to a trapezoidal shape only by giving the offset to the projection image, the CPU 101 performs electrical keystone correction by image processing to correct the projection image from a trapezoidal shape to a rectangular shape. An initial correction value for correcting the projected image into a rectangular shape is stored in the memory in the CPU 101 in advance. The CPU 101 reads an initial correction value corresponding to the offset adjustment amount, performs keystone correction processing on the image data to be projected based on the read initial correction value on the memory 102, and controls projection of the image data after the keystone correction processing. Send to circuit 64.

(Focus adjustment of projected image)
By shifting the focus lens that constitutes the projection lens 61 in the optical axis direction, the projector unit 6 adjusts the focus of the projected image. When performing focus adjustment, the CPU 101 sends a focus adjustment signal to the projection control circuit 64 in accordance with an operation signal from the operation member 11.

(Zoom adjustment of projected image)
The projector unit 6 performs zoom adjustment of the projected image by shifting the zoom lens constituting the projection lens 61 in the optical axis direction. The CPU 101 sends a zoom adjustment signal to the projection control circuit 64 in accordance with the operation signal from the operation member 11.

(Safety device)
When the detection signal is input from the proximity sensor 111, the CPU 101 prohibits projection by the projector unit 6. When projection is prohibited, at least illumination by the LED light source 63 is turned off.

(Display device switching)
Whether the CPU 101 reproduces an image on the projector unit 6, reproduces an image on the liquid crystal display 12, displays on an external TV monitor, or displays on an external HD monitor is set by a display device changeover switch. Whenever a display device switching operation signal is input from the display device switch constituting the operation member 11, the CPU 101 selects a display device for image reproduction from “projector unit 6” → “liquid crystal display 12” → “TV monitor” → The screen is cyclically switched in the order of “HD monitor” → “projector unit 6”.

  When projecting from the projector unit 6, the CPU 101 sends a projection command to the projector unit 6. When displaying on the liquid crystal display 12, the CPU 101 sends a display command to the liquid crystal display 12. When displaying on the TV monitor, for example, the CPU 101 generates a video signal corresponding to 525 scanning lines, and outputs the generated signal from the TV output terminal 105. When displaying on the HD monitor, for example, the CPU 101 generates a video signal corresponding to 1125 scanning lines, and outputs the generated signal from the HD output terminal 106.

(Source switching)
Which content image is to be reproduced by the CPU 101 is set by a source changeover switch. Each time the CPU 101 receives a source switching operation signal from a source switching switch that constitutes the operation member 11, the content of the image to be reproduced is sent to the source 1. → Source 2. → Source 3. → Source 1. Switch cyclically in this order, and change the input source of image data. However, if the memory card 110 is not attached to the projector 10, the source 1. To skip. If no external device is connected to the external interface (I / F) 104, the source 3. To skip.

Source 1. 1. Reproduced image source based on data read from the memory card 110 2. Reproduced image source based on data read from the hard disk drive device (HDD) 103 Reproduced image by data input from external interface (I / F) 104

  The CPU 101 uses the source 1. Or source 2. When the image corresponding to is reproduced, the image data with the newest recording date and time (the last recorded image data taken) is read sequentially from the memory card 110 (or the hard disk drive device 103). The read data is used not only to generate reproduction data to be sent to the projector unit 6 or the liquid crystal display 12, but also to generate a video signal to be output to an external TV monitor (or HD monitor).

According to the first embodiment described above, the following operational effects can be obtained.
(1) Since any one of display data, projection data, and video signal with different resolutions is generated selectively according to the set display device, the projector unit 6 and the liquid crystal display The CPU 101 can be shared as reproduction data generating means between the device 12, the external TV monitor and the HD monitor, and the cost can be reduced. In addition, since it is not necessary to simultaneously generate data (video signals) having a plurality of resolutions, the burden on the CPU 101 is reduced, and a reproduced image is displayed (projected) at a comfortable speed without using a CPU for high-speed processing. be able to.

(2) Since the reproduction data (or video signal) with the resolution corresponding to the display device is generated in real time at the time of image reproduction, the display data, the projection data, and the video signal with different resolutions are generated in advance to generate a hard disk. It may not be stored in a storage device such as the drive device (HDD) 103. Thereby, the used capacity of the storage device can be saved.

(3) Since projection by the projector unit 6 is prohibited when a detection signal is input from the proximity sensor 111, useless projection operation can be prevented and power consumption and heat generation can be suppressed.

(Modification 1)
Instead of the proximity sensor 111, a mechanical switch may be provided. In this case, the microswitch is disposed on the surface of the projector 10 housing having the opening of the projector unit 6. The micro switch outputs a detection signal to the CPU 101 when the casing of the projector 10 is placed with the opening surface of the projector unit 6 facing down, or when the opening surface is in contact with another object.

(Second embodiment)
The switching of the display device may be configured to be set on the “menu screen” instead of the operation signal from the display device switching switch. In this case, menu setting performed on the projector 10 will be described.

  The projector 10 displays a “display device setting menu” screen on the liquid crystal display 12 when a menu key constituting the operation member 11 is pressed. FIG. 3 is a diagram illustrating a “display device setting menu” screen. In FIG. 3, four items “1. LCD”, “2. Projector projection”, “3. TV output”, and “4. HD output” are displayed.

  In this state, when the screen operation cursor key (cross key) constituting the operation member 11 is operated downward, the projector 10 moves the cursor position downward, and when the cross key is operated upward. The projector 10 moves the cursor position upward. An operation signal in the vertical direction by the cross key displayed on the menu screen corresponds to an item selection instruction. In the example of FIG. 3, the cursor is placed on the item “2. Projector projection”. Note that the item on which the cursor is placed on the “display device setting menu” screen that is first activated in response to the pressing operation of the menu key indicates the display device set at that time.

  In conjunction with the item selection instruction, the projector 10 displays the item number at which the cursor is placed in the “output destination” box indicating the display device (“2” in the example of FIG. 3). The projector 10 displays a check box “OK” when the cross key 11 constituting the operation member 11 is operated leftward, and displays a “display device setting menu” screen when the menu key is further pressed. At the same time, the display device corresponding to the number displayed in the “output destination” box is determined. In other words, the setting of the display device is changed to the projector unit 6.

  The projector 10 displays a check box “cancel” when the cross key 11 constituting the operation member 11 is operated in the right direction, and further displays it in the “output destination” box when the menu key is pressed. Regardless of the number, the setting contents before the menu screen display are restored, and the display of the “display device setting menu” screen is terminated. In this case, the setting of the display device is not changed.

  According to the second embodiment described above, since the switching of the display device can be set on the “menu screen”, the switching state of the display device can be notified to the user. That is, the user can confirm the setting state of the display device from the menu screen displayed on the liquid crystal display 12.

(Modification 2)
A cable connection detection switch may be provided in each of the TV output terminal 105 and the HD output terminal 106 so that a video signal is output to the output terminal that detects the cable connection. In this case, the CPU 101 detects a cable connection to the TV output terminal 105 regardless of whether the display device is switched to the projector unit 6 or the liquid crystal display 12 by the display device changeover switch or the “display device setting menu”. Instead of generating projection data for the projector unit 6 (or display data for the liquid crystal display 12), a video signal corresponding to 525 scanning lines is generated, and this video signal is output from the TV output terminal 105. To do.

  In addition, when the CPU 101 detects the cable connection to the HD output terminal 106, it replaces the generation of the projection data for the projector unit 6 (or the display data for the liquid crystal display 12) and the video corresponding to 1125 scanning lines. A signal is generated, and this video signal is output from the HD output terminal 106.

  When cable connection to both the TV output terminal 105 and the HD output terminal 106 is detected, a video signal corresponding to 1125 scanning lines with high resolution is generated, and this video signal is output from the HD output terminal 106. .

(Modification 3)
The number of scanning lines of the video signal generated when the cable connection to both the TV output terminal 105 and the HD output terminal 106 is detected may be configured to be selectable without being limited to a higher resolution. The selection operation is preferably performed on the “menu screen”.

(Third embodiment)
The projector 10 of the third embodiment reads the management information of the reproduction data from the memory card 110 or the hard disk drive device (HDD) 103, and switches the display device based on this management information. The reproduction data management information is configured to be able to designate a display device for image reproduction for each file in which image data is stored.

  FIG. 4 is a diagram for explaining a management file in which management information of reproduction data is recorded. The management file is provided separately from the image file and is stored in the hard disk drive (HDD) 103 or the memory card 110. In FIG. 4, for each image file “file id = 1”, “file id = 2”,..., The output destination (display device) of the reproduced image based on the data in the image file is shown. According to FIG. 4, the file name “file id = 1” is “image.jpg”, and the output destination (display device) of the reproduced image based on the data in this image file is “projector”, that is, the projector unit 6. is there.

  When the CPU 101 is instructed to reproduce an image based on the data recorded in the image file with the file name “image.jpg”, the CPU 101 refers to the management file and outputs an output destination (in this example, a projector). A projection command is sent to part 6). The CPU 101 further reads out image data from the file with the file name “image.jpg”, generates projection data using this data, and sends the generated data to the projector unit 6.

According to the third embodiment described above, the following operational effects can be obtained.
(1) A management file for recording management information of reproduction data is provided, and an output destination (display device) of a reproduction image based on data in the image file can be set for each image file. For example, the output destination (display device) for an image file that you do not want to show to others is the liquid crystal display 12, and the output destination (display device) for the image file that you want to show to others is the projector unit 6. 10 can select a display device that automatically reproduces an image.

(2) Since the management file is provided separately from the image file, the output destination (display device) for all the image files can be designated by one management file, so that management is easy.

(Modification 4)
Information indicating the output destination (display device) of the reproduced image may be included in the name of the image file. For example, when an instruction is given to reproduce an image based on the data recorded in the image file name “proj_out.jpg”, the CPU 101 issues a projection command to the output destination (the projector unit 6 in this example) indicated by the file name. Send. The CPU 101 further reads out image data from the file with the file name “proj_out.jpg”, generates projection data using this data, and sends the generated data to the projector unit 6.

(Fourth embodiment)
The reproduction data management information according to the fourth embodiment is configured to be able to designate a display device for image reproduction for each folder in which image files are stored.

  FIG. 5 is a diagram for explaining a management file in which management information of reproduction data is recorded. The management file is provided separately from the image file and is stored in the hard disk drive (HDD) 103 or the memory card 110. In FIG. 5, for each folder “folder id = 1”, “folder id = 2”,..., The output destination (display device) of the reproduced image by the image file in the folder is shown. According to FIG. 5, the folder name of “folder id = 1” is “image”, and the output destination (display device) of the reproduction image by the data in all the image files stored in this folder is “projector”. That is, the projector unit 6.

  When the CPU 101 is instructed to reproduce an image based on the data of the image file recorded in the folder with the folder name “image”, the CPU 101 refers to the management file and outputs an output destination defined in the management file (in this example, A projection command is sent to the projector unit 6). The CPU 101 further reads out image data from the designated image file, generates projection data using this data, and sends the generated data to the projector unit 6.

  According to the fourth embodiment described above, the management file for recording the management information of the reproduction data is provided, and the output destination (display device) of the reproduction image based on the data in the image file is set for each folder storing the image file. Configured to be configurable. By storing the image file in a different folder according to the output destination (display device) of the reproduced image, it is easy for the user to handle and manage.

(Modification 5)
In the management file for recording the management information of the playback data, the output destination (display device) of the playback image based on the data in the image file may be set for each recording medium storing the image file. By storing the image file in a different recording medium depending on the output destination (display device) of the reproduced image, it is easy for the user to handle and manage.

(Modification 6)
Information indicating the output destination (display device) of the reproduced image may be included in the folder name. For example, when an instruction is given to reproduce an image based on the image file data recorded in the folder name “proj_out”, the CPU 101 issues a projection command to the output destination (the projector unit 6 in this example) indicated by the folder name. Send. The CPU 101 further reads out image data from the designated image file, generates projection data using this data, and sends the generated data to the projector unit 6.

(Fifth embodiment)
In the above embodiment, an example in which an image is reproduced on one display device among a plurality of display devices has been described. However, an image is reproduced on two display devices among the plurality of display devices, and no image is reproduced on any display device ( That is, image reproduction may be prohibited). In this case, as in the third embodiment, it is preferable to record the output destination (display device) of image reproduction for each image file in the management file.

  FIG. 6 is a diagram illustrating a menu screen for setting a display device that outputs a reproduction image. The projector 10 displays the setting menu screen of FIG. 6 on the liquid crystal display 12 when a menu key constituting the operation member 11 is pressed. According to FIG. 6, check boxes for “LCD” and “projector” are provided for each image file. When the check box is checked, the projector 10 controls to display a reproduced image by the corresponding image file on the corresponding display device.

  The check boxes for the image files with the file names “DSCN0001.JPG”, “DSCN0003.JPG”, and “DSCN0007.JPG” are checked only on the “LCD” side. In this case, the output destination (display device) of the reproduced image based on the data in each image file is the liquid crystal display 12 and is controlled so as not to project from the projector unit 6.

  In the check boxes of the image files with the file names “DSCN0002.JPG”, “DSCN0004.JPG”, “DSCN0005.JPG”, and “DSCN0008.JPG”, “LCD” and “Projector” are respectively checked. In this case, the output destination (display device) of the reproduced image based on the data in each image file is controlled as both the liquid crystal display 12 and the projector unit 6.

  In the check box of the image file with the file name “DSCN0006.JPG”, neither “LCD” nor “Projector” is checked. In this case, the reproduction image based on the data in the image file is controlled not to be displayed (projected) on the liquid crystal display 12 or the projector unit 6.

  The check boxes for the image files with the file names “DSCN0009.JPG” and “DSCN0010.JPG” are checked only on the “projector” side. In this case, the output destination (display device) of the reproduced image based on the data in the image file is the projector unit 6 and is controlled not to be displayed on the liquid crystal display 12.

  The next file with the file name “DSCN0010.JPG” is displayed when the cursor key (cross key) for operating the screen constituting the operation member 11 is operated downward with the file “DSCN0010.JPG” selected. The When the check box “OK” is selected by the pointer operation member constituting the operation member 11 and the determination key is further pressed, the projector 10 ends the display of the “display device setting menu” screen and displays the reproduced image. The output destination (display device) is determined as the display device whose check box is checked. When the check box “cancel” is selected by the pointer operation member constituting the operation member 11 and the determination key is further pressed, the projector 10 ends the display of the “display device setting menu” screen and Regardless of what is checked, the previous settings are retained.

  The projector 10 records management information describing the output destination (display device) of the reproduced image for each image file determined as described above in the memory card 110 or the hard disk drive device (HDD) 103. Note that the initial state before the setting is changed in the setting menu is that the check box on the “LCD” side is checked and the check box on the “projector” side is blank (unchecked) for all image files.

  A flow of reproduction processing executed by the CPU 101 when the projector 10 performs image reproduction will be described with reference to a flowchart of FIG. When an operation signal instructing the start of information reproduction is input from the operation member 11, the CPU 101 starts the process of FIG.

  In step S61 in FIG. 7, the CPU 101 reads an image file from the memory card 110 or the hard disk drive (HDD) 103, develops image data in the file in the memory 102, and proceeds to step S62. The image file is read from a folder designated in advance in the memory card 110 or the hard disk drive (HDD) 103.

  The projector 10 is configured to be able to select a single frame reproduction method for displaying (projecting) one image on one screen and a list reproduction method for displaying (projecting) a plurality of images on one screen by an operation signal from the operation member 11. ing. In this embodiment, a list reproduction method will be described as an example. In the list reproduction method, nine image files are read in order to display, for example, nine frames of images on one screen.

  In step S62, the CPU 101 determines whether the LCD is on. When the on operation signal is input from the LCD switch (not shown) constituting the operation member 11, the CPU 101 makes an affirmative decision in step S62 and proceeds to step S63, and the on operation signal is input from the LCD switch (not shown). If not, a negative determination is made in step S62, and the process proceeds to step S75. The CPU 101 operates the liquid crystal display 12 when an affirmative determination is made in step S62, and does not operate the liquid crystal display 12 when a negative determination is made in step S62.

  In step S63, the CPU 101 determines whether or not the PJ is on. When an on operation signal is input from a projector switch (not shown) constituting the operation member 11, the CPU 101 makes an affirmative decision in step S63 and proceeds to step S64, and an on operation signal is input from the projector switch (not shown). If not, a negative determination is made in step S63, and the process proceeds to step S72. The CPU 101 operates the projector unit 6 when the determination in step S63 is affirmative, and does not operate the projector unit 6 when the determination is negative in step S63.

  In step S64, the CPU 101 acquires the setting content for PJ, and proceeds to step S65. Specifically, the management information described above is read, and the check contents of the “projector” check box regarding the image file read in step S61 are acquired.

  In step S65, the CPU 101 acquires the setting content for the LCD and proceeds to step S66. Specifically, the management information described above is read out, and the check contents of the “LCD” check box regarding the image file read out in step S61 are acquired.

  In step S66, the CPU 101 determines whether there is a PJ check. If the “projector” check box is checked for the image file read in step S61, the CPU 101 makes an affirmative decision in step S66 and proceeds to step S67. If the “projector” check box is not checked, A negative determination is made in step S66 and the process proceeds to step S70.

  In step S67, the CPU 101 causes the projector unit 6 to project a reproduced image based on an image file in which the “projector” check box is checked among the image files developed in the memory 102, and the process proceeds to step S68. In the case of the single frame playback method, a playback image is projected from the projector unit 6 frame by frame.

  In step S68, the CPU 101 determines whether there is an LCD check. The CPU 101 makes an affirmative decision in step S68 when the “LCD” check box is checked for the image file projected in step S67, and proceeds to step S69. If the “LCD” check box is not checked, A negative determination is made in step S68 and the process proceeds to step S79.

  In step S69, the CPU 101 causes the liquid crystal display 12 to display a reproduced image based on the image file in which the “LCD” check box is checked among the image files projected in step S67, and then the process proceeds to step S70. FIG. 8 is a diagram illustrating a list display screen displayed on the liquid crystal display 12 when all the check boxes are checked for all the image files read out in step S61. The CPU 101 generates display data for list display on the memory 102 and sends the generated display data to the liquid crystal display 12. In the case of the single-frame playback method, data for displaying a playback image using the single-frame image file read in step S 61 is generated, and the generated display data is sent to the liquid crystal display 12.

  FIG. 9 is a diagram illustrating a list display screen projected from the projector unit 6 in step S67 when the check box is checked as illustrated in FIG. 6 for the image file read in step S61. According to FIG. 9, only the playback image of the image file whose “projector” check box is checked is projected, and the existence of an image file whose “projector” check box is not checked is hidden on the projection screen. . If the “projector” check box is checked for all the image files read in step S61, the projector unit 6 projects a list display screen similar to FIG.

  In step S79, the CPU 101 causes the liquid crystal display 12 to display a playback image based on the image file developed in the memory 102 for the image file whose “LCD” check box is checked, and the “LCD” check box is checked. For a non-displayed image file, a mark indicating non-display (non-playback) setting (for example, x in a square) is displayed on the liquid crystal display 12 and the process proceeds to step S70.

  FIG. 10 is a diagram illustrating a list display screen displayed on the liquid crystal display 12 in step S79 when the check box is checked as illustrated in FIG. 6 for the image file read in step S61. According to FIG. 10, the existence of only the image file whose “projector” check box is checked is clarified, and only the playback image of the image file whose “LCD” check box is checked is displayed. A mark indicating non-display setting is displayed for an image file in which the “LCD” check box is not checked. In the case of the single frame playback method, if the “LCD” check box is not checked for the single frame image file read in step S61, a mark indicating non-display setting is displayed on the liquid crystal display 12.

  In step S70, the CPU 101 determines whether an image switching instruction has been issued. When an operation signal for instructing switching of an image to be reproduced and displayed (projected) to a reproduced image based on another image file is input from the operation member 11, the CPU 101 makes an affirmative decision in step S70 and returns to step S61. When the operation signal for instructing switching of the reproduced image is not input from the operation member 11, the CPU 101 makes a negative determination in step S70 and proceeds to step S71.

  In step S71, the CPU 101 determines whether or not an instruction to switch to another mode (for example, the first embodiment) has been given. When an operation signal for instructing switching to another mode is input from the operation member 11, the CPU 101 makes a positive determination in step S <b> 71, ends the process of FIG. 7, and starts the process of the other mode. When the operation signal instructing switching to another mode is not input from the operation member 11, the CPU 101 makes a negative determination in step S71 and returns to step S62.

  In step S72, the CPU 101 acquires the setting content for LCD and proceeds to step S73. Specifically, the management information described above is read out, and the check contents of the “LCD” check box regarding the image file read out in step S61 are acquired.

  In step S73, the CPU 101 determines whether there is an LCD check. The CPU 101 makes an affirmative decision in step S73 if the “LCD” check box is checked for the image file read in step S61, and proceeds to step S74. If the “LCD” check box is not checked, A negative determination is made in step S73 and the process proceeds to step S80.

  In step S74, the CPU 101 causes the liquid crystal display 12 to display a reproduced image based on the image file in which the “LCD” check box is checked among the image files developed in the memory 102, and the process proceeds to step S70. In step S80, the CPU 101 causes the liquid crystal display 12 to display a playback image based on the image file developed in the memory 102 for the image file in which the “LCD” check box is checked, and the “LCD” check box is checked. For a non-displayed image file, a mark indicating non-display setting (for example, x in a square) is displayed on the liquid crystal display 12, and the process proceeds to step S70.

  FIG. 11 is a diagram illustrating a list display screen displayed on the liquid crystal display 12 in step S80 when the check box is checked as illustrated in FIG. 6 for the image file read in step S61. According to FIG. 11, the existence of all the image files read in step S61 is clarified, and only the reproduced images of the image files whose “LCD” check box is checked are displayed, and the “LCD” check box is displayed. A mark indicating non-display setting is displayed for an image file for which is not checked. In the case of the single frame playback method, if the “LCD” check box is not checked for the single frame image file read in step S61, a mark indicating non-display setting is displayed on the liquid crystal display 12.

  In step S75, the CPU 101 determines whether the PJ is on. When an on operation signal is input from a projector switch (not shown) constituting the operation member 11, the CPU 101 makes an affirmative decision in step S75 and proceeds to step S76, and an on operation signal is input from the projector switch (not shown). If not, a negative determination is made in step S75, and the process proceeds to step S71.

  In step S76, the CPU 101 acquires the setting content for PJ, and proceeds to step S77. Specifically, the management information described above is read, and the check contents of the “projector” check box regarding the image file read in step S61 are acquired.

  In step S77, the CPU 101 determines whether or not there is a PJ check. If the “projector” check box is checked for the image file read in step S61, the CPU 101 makes an affirmative decision in step S77 and proceeds to step S78. If the “projector” check box is not checked, A negative determination is made in step S77, and the process proceeds to step S70.

  In step S78, the CPU 101 causes the projector unit 6 to project a reproduced image based on an image file in which the “projector” check box is checked among the image files developed in the memory 102, and the process proceeds to step S70. When the check box is checked as illustrated in FIG. 6 for the image file read out in step S61, the list display screen projected from the projector unit 6 in step S78 is the same as that in FIG. In the case of the single frame reproduction method, a reproduction image by the single frame image file read out in step S61 is projected from the projector unit 6.

According to the fifth embodiment described above, the following operational effects can be obtained.
(1) Of the four types of output destinations of the playback image output by the projector 10, the mode of outputting to the LCD and the projector, the mode of outputting to the LCD or the projector, and the mode of not outputting to the LCD or the projector can be switched. Therefore, the options for image reproduction can be expanded as compared with the case of always outputting to one output destination. The resolution of the liquid crystal display 12 and the resolution of the projector unit 6 may be the same (for example, horizontal 640 × 400 pixels).

(2) When the liquid crystal display 12 is activated and the projector unit 6 is deactivated, a reproduction image by an image file whose “LCD” check box is checked among the image files read in step S61 is displayed on the liquid crystal display. A mark indicating non-display setting is displayed on the liquid crystal display 12 for the image file in which the “LCD” check box is not checked (steps S73, S74, S80). By displaying the mark indicating the non-display setting, it is possible to notify the user of the projector 10 that there is an image file that is not displayed (reproduced).

(3) When the liquid crystal display 12 is deactivated by operating the projector unit 6, the reproduced image by the image file whose “projector” check box is checked among the image files read in step S 61 is displayed. Projection is started from 6 and information indicating the existence of the image file is not included in the projection content for the image file for which the “projector” check box is not checked (steps S77 and S78). By not projecting the mark indicating the non-display setting, there is no possibility that the observer of the projected image may have suspicion about the mark.

(4) When both the projector unit 6 and the liquid crystal display 12 are operated, only the image file in which the “projector” check box is checked among the image files read in step S61 is displayed. In this case, the playback image is projected from the image file to be displayed from the projector unit 6, and information indicating the presence of the image file is not included in the projection content for the image file that is not the display target (steps S 66 and S 67). One liquid crystal display 12 displays a playback image based on an image file in which the “LCD” check box is checked among the image files to be displayed, and an image file in which the “LCD” check box is not checked. Displayed a mark indicating the non-display setting (steps S68, S69, S79). By projecting (displaying) a common image file on the projection screen of the projector unit 6 and the display screen of the liquid crystal display 12, the correspondence relationship is easily understood by the user of the projector 10. Further, since the mark indicating the non-display setting is not projected on the projection screen of the projector unit 6, there is no possibility that the observer of the projected image may be suspicious of the mark.

(Modification 7)
In the fifth embodiment, in the case of list display and single frame display, the example in which the output destination (display device) of the reproduced image is determined according to whether or not the check box is checked has been described. In addition to the list display and the single frame display, the present invention may be applied to a slide show display.

(Modification 8)
In addition, a configuration in which a playback image output destination (display device) is determined depending on whether a check box is checked is applied to a list display and a single frame display, and to a slide show display. The method and the method applied in any case may be configured to be selectable by an operation signal from the operation member 11. The initial state in this case applies only to the slide show display for the “LCD” check box, and applies to the slide show display, list display, and single frame display for the “projector” check box. It is preferable to make it.

(Modification 9)
When only the image file whose “projector” check box is checked is to be displayed as in the case where the screen illustrated in FIG. 10 is displayed on the liquid crystal display 12 (when the existence of the image file is notified). If any one of the operation for deleting the image file of all frames, the operation for deleting the folder including the image file, and the operation for reformatting the memory card 110 or the hard disk drive device (HDD) 103 is performed, the liquid crystal display 12 is made to display a warning. For example, by displaying the message “There are image files that are not displayed on the LCD screen. Are these image files allowed to be lost?”, It is possible to prevent the image files from being accidentally lost.

(Modification 10)
Instead of the modification 9, when only the image file whose “projector” check box is checked is to be displayed (when notifying the existence of the image file), an operation of deleting the image files of all frames, Both the operation for deleting the folder including the image file and the operation for reformatting the memory card 110 or the hard disk drive device (HDD) 103 may be prohibited (invalidated).

(Modification 11)
The number of frames displayed in one screen in the list reproduction method is not limited to the nine frames described above, and may be four frames or 16 frames.

(Modification 12)
For image files in which the “LCD” check box is not checked, a mark indicating the non-display setting (for example, “X” in a square) is displayed on the liquid crystal display 12. When the number of frames is equal to or greater than a predetermined number (when the display size per frame is equal to or smaller than the predetermined size), the image of the frame may be reproduced and displayed without displaying the non-display setting mark. This is because if the display image size is reduced to some extent, even if the display image is viewed, its contents cannot be understood.

(Modification 13)
The example in which the check box is checked / unchecked has been described in the setting menu. However, the check box may be configured to be changeable even in a list display or a single frame display. In this case, the CPU 101 displays a check box next to the file name of the playback image being displayed when a predetermined password is input in the state of list display and single frame display, for example. Control to check / uncheck the check box.

(Modification 14)
Although an example in which check boxes are provided for “LCD” and “projector” has been described, a check box may also be provided for “TV output” and “HD output”. Also in this case, as in the fifth embodiment, since the “LCD” is exclusively observed by the user of the projector 10, the presence of an image file that is not displayed (reproduced) is also included in the display content. “HD output” is observed by a large number of observers in the same manner as “projector”, and therefore, an image file that is not displayed (reproduced) is excluded from display contents so that the existence of the image file is not known.

  Although the projector 10 has been described as an example of an electronic device including a plurality of image reproducing means, the present invention can also be applied to a mobile phone with a projector, a camera with a projector, a television with a projector, a radio with a projector, and the like.

  The above description is merely an example, and is not limited to the configuration of the above embodiment.
