Description

  The present invention relates to an image conversion system.

  In an image recording / reproducing apparatus such as a digital still camera (DSC), a captured image is converted into electrical image data, and the converted image data is recorded on a recording medium such as an IC memory card or a floppy disk (FD). The image data can be transmitted via a communication line. On the receiving side, image data received via the communication line is reproduced using a similar image recording / reproducing apparatus.

  In such a system, since an IC card used as a recording medium has a common shape and electrical specifications, it can be used in a system using various image recording / reproducing apparatuses. Various data management systems (OS) including image data differ depending on the employed image recording / reproducing apparatus, but generally a system that reproduces image data obtained by a digital still camera on a personal computer or the like is common. .

FIG. 19 shows a configuration diagram and an explanatory diagram of this conventional system.
Camera image data obtained by the camera is recorded on an IC memory card. Image data is read from the IC memory card via a card interface on the personal computer side, stored, converted into personal computer (PC) data by performing conversion processing determined for each personal computer system, and used as a personal computer image. Conversely, when using the computer image data obtained on the personal computer side on the camera side, the personal computer image is converted into camera image data suitable for the camera and recorded on the IC memory card. Play back on the monitor.

  As described above, the camera (DSC) image of the digital still camera centering on the video signal system and the personal computer (PC) image of the personal computer are different in basic configuration. For example, as shown in FIG. Aspect ratio and interlace are different. In FIG. 20, regarding the pixel structure, the DSC image is 768 × 480 (frame mode), 768 × 240 (field mode), and the like, and the PC image is 640 × 480, 640 × 400, 1024 × 768, and the like. Regarding the image signal, the DSC image is a Y / C signal, while the PC image is an RGB signal. The DSC image has an aspect ratio of 4: 3 and screen scanning is interlaced, whereas the PC image has an aspect ratio of 1: 1 and screen scanning is non-interlaced.

  As described above, in the conventional system, the image data obtained by the digital still camera cannot be efficiently displayed at the transmission destinations having different display forms. In this system, the present application proposes a system that can cope with a display mode that is reasonably necessary.

In order to solve the above-described problems, an image conversion system according to the present invention includes:

In addition, a camera that transmits via a transmission means;
An image conversion device capable of converting the first image data into second image data, wherein the first image data transmitted from the camera is converted based on the data. While it is possible to generate second image data corresponding to the display form in the image conversion apparatus that is the transmission destination, the camera receives the image data corresponding to the display form in the apparatus input to the image conversion apparatus. An image conversion device that performs conversion processing to image data corresponding to a display form, and that can transmit the image data to the camera after the conversion processing ends;
An image conversion system.

  In the image conversion system according to the present invention, image data is generated on the camera side, and the image data itself transmitted from the camera is converted to an image conversion device such as a personal computer that converts the image data. When data for conversion to image data corresponding to the display mode of the personal computer is transmitted from the camera to the personal computer in combination with the image data itself, the image conversion processing on the personal computer side can be performed smoothly. In addition, even image data input to a personal computer and corresponding to the display mode of the personal computer can be converted into the camera display mode and transmitted to the camera so as to be compatible with the camera display mode.

In addition, the display program is recorded on the recording medium together with the image data, thereby enabling immediate display on the receiving side (other device side). The display program is a program that decompresses and displays an image when the image data is compressed, and can add information (name, age, ID number, etc.) to the image. As described with reference to FIG. 20, the conversion program is a conversion program necessary for displaying an image in a display system having an image structure different from the image structure recorded on the recording side. For example, an NTSC image file is converted into an RGB file. It is a program to convert to. Also, in the format of the recording medium, the format itself is adapted to the management system (OS) on the receiving side, the image data is recorded in a standard form, and the image data is converted so that it can be adapted to each management system with the transfer software. good.

  The IC memory card has a structure as shown in FIG. 7, conforms to a standard such as JEIDA, and is divided into a nonvolatile memory (EEPROM) and a common memory (SRAM) area. Device information (TUPLE) such as device type, capacity, and speed is stored in the nonvolatile memory. The common memory has management information such as version (Ver. 4.0), block length, initialization date, other attribute information (TUPLE) such as manufacturer individual information, manufacturer name, BPB, FAT, directory, etc. (BOOT, FAT, DIR) recording area, image file (ROOT), audio file (ROOT), image file (SUB1), audio file (SUB1), control file subdirectory, recording data for recording program file (DATA-) FILE) recording area (data area) and the like.

  FIG. 8 shows a structure diagram of a data area of an IC card used in a digital still camera. As shown in FIG. 8A, the data area shown in FIG. 7 includes a program file, a control file, and a subdirectory in addition to an image file and an audio file. The root directory is configured as shown in FIG.

  The camera according to the present embodiment can employ the same configuration as that shown in FIGS. 3 and 4, and image data, program data, and the like are transmitted to the communication line via the serial communication IF 20.

  FIG. 9 shows a card formatting procedure in this embodiment. This format is basically the same as the format shown in FIG. 4, except that the management system (OS) selection in step S2 in FIG. 4 is the OS selection (step S2 ′) on the transfer side in this embodiment. . The configuration of the personal computer on the receiving side in this embodiment is the same as in FIG.

  As shown in FIG. 10, the processing on the reception side (personal computer side) performs communication preparation processing such as modem setting and communication speed setting when the personal computer side is in the transmission mode (step S31) and reaches the communication OK state. (Step S32), the transmission side (camera side) is instructed to start transfer (step S33), and the received image data is recorded in the main memory (step S34). Subsequently, it is determined whether or not the communication has been normally completed (step S35). If the communication has not been completed, the process returns to step S32. If the communication has been completed, the data is converted to a file (step S36). The data is stored in a hard disk (HDD), floppy disk (FD), magneto-optical disk (MO) or the like (step S37).

  An example of the structure of each file is shown in FIG. The image file is composed of a file header and an image data body. The image data body has a recording area for DSC specifications, version, image data recognition information, comments, and the like, and a compressed image data recording area as shown in the figure. Similarly, the audio file and the control file include a file header and an audio data body or control data body. The audio data body has a DSC specification, a version, audio data recognition information, a comment recording area, and a compressed audio data (such as ADPCM) recording area. The control data body has a DSC specification, version and comment recording area, and a control data (SEND INFO. Telephone number, MS-DOS, etc.) recording area. The display process on the personal computer side in this embodiment is the same as the process shown in FIG.

  The file conversion on the camera side and personal computer side in this embodiment is performed as shown in FIG. 12, for example. On the camera side, the image file F1 and the display program file F2 are combined and transmitted as one file F. On the personal computer side, the received file F is divided to obtain the image file F1 and the display program file F2. Perform file conversion.

Next, still another embodiment of the present invention will be described.
In this embodiment, when the recorded image data is transmitted to another device, a plurality of images to be transmitted can be designated by a normal key operation.

  In the conventional system as described above, the selective transmission of the image file from the camera side is performed by transmitting the image being reproduced as one image (file) by a key operation or as a management information file such as a control file. A plurality of images are specified, and a plurality of images (a plurality of files) are continuously transmitted. However, it is difficult to specify a plurality of files by key operation because the number of keys is small in an apparatus such as a camera that is preferably originally downsized.

  In this embodiment, even a small device such as a camera with a small number of keys can easily specify a plurality of images and perform continuous image transmission. Multiple image designation is managed by.

FIG. 13 is a flowchart showing the operation processing procedure of this embodiment.
In the transmission mode in which a plurality of images are designated and transmitted from the camera side, it is determined whether or not the right arrow switch 14D is operated after the reproduction operation (step S41) (step S42). Is reproduced (step S44), and if not operated, it is determined whether or not the left arrow switch 14C is operated (step S43). Here, if operated, the previous image is reproduced (step S45), and if not operated, it is determined whether the trigger 1 switch 14A is ON (step S46). If the trigger 1 switch 14A is not ON, the process returns to the process of step S42. If it is ON, the entry NO. Is acquired (step S47), and the entry NO. Is stored (step S48). Subsequently, it is determined whether or not the trigger 2 switch 14B is ON (step S49). If it is not ON, the process returns to step S42, and if it is ON, a transmission process is performed (step S50), and the process is terminated.

  14 and 15 show flowcharts of processing procedures of the image transmission side device and the reception side device.

  14 and 15, on the image transmission side (see FIG. 14), when it is first recognized that the modem is connected (step S51), it waits for the communication switch 14F to turn on (step S52). A “communication request” command is transmitted to the image receiving side (step S53). On the other hand, the image receiving side (see FIG. 15) similarly recognizes the modem connection (step S71), waits for confirmation of reception of the “communication request” command from the image transmitting side (step S72), and It is determined whether or not the reception operation can be normally performed (OK) (step S73). This determination is based on whether a memory card is inserted in the receiving device (for example, a camera), whether the memory card is not protected, whether the memory card has sufficient free space, or whether the memory card is formatted. Or the like. If it is not OK in step S73, an NG command is transmitted (step S75), and the process proceeds to step S92.

  If it is determined in step S73 that it is OK, an “OK” command is transmitted to the image transmission side (step S74), and a telephone mark and a record “REC” are displayed on the LCD 18 shown in FIG. 1 (step S76).

  When the image transmission side confirms the reception of the “OK” command (step S54), the LCD of the camera is turned on to display a telephone mark and reproduction “PLAY” (step S55). Here, the user selects an image to be transmitted using the left arrow switch 14C or the right arrow switch 14D. If it is determined that the “OK” command has not been received, the process proceeds to step S64.

  Next, a “data transmission START” command is transmitted to the image receiving side (step S56). When the image receiving side receives the “data transmission START” command (step S77), it determines whether or not the size of the transmission image data file is larger than the receiving side memory card free space (OK) (step S78). If it is determined that it is not OK, an “NG” command is transmitted (step S80), and the process proceeds to step S92. If it is determined to be OK, an “OK” command is transmitted to the image transmission side.

  The image transmission side confirms reception of this “OK” command (step S57). If not received, the process proceeds to step S64. When reception is confirmed, data is transmitted and the LCD blinks (telephone). The mark blinks) (step S58), and a "data transmission end" command is transmitted (step S59). On the image receiving side, reception of the “end data transmission” command is confirmed (step S83), and if not received, the process returns to step S81.

  On the image transmission side, after sending a “data transmission end” command to the image reception side in step S59, the reception of the “retransmission request” command from the image reception side is confirmed (step S60). The process returns to step S56. In step S60, if the “retransmission request” command has not been received, the reception of the “OK” command is confirmed (step S61). If not received, the process proceeds to step S64. Is turned on (step S62), it is determined that the communication switch 14F is “OFF”. If not “OFF”, the process returns to step S56, and if “OFF”, the “communication end” command is received. (Step S64).

  On the image receiving side, reception of the “communication end” command is confirmed (step S92). If not received, the process returns to step S77. If reception is confirmed, an “OK” command is transmitted to the image transmitting side ( Step S93), the LCD is turned off (Step S94), and the process is terminated.

  The reception on the image transmission side of the “OK” command transmitted in step S93 is confirmed (step S65). If not received, the process returns to step S64. When the reception is confirmed, the LCD is turned off. (Step S66), the process ends.

  On the other hand, on the image receiving side, when the “data transmission end” command transmitted from the image transmitting side in step S59 is received, the received image is reproduced (step S84), and the left arrow switch 14C is pressed because the user requests retransmission. It is determined whether or not an operation has been performed (step S85). Here, if the switch is operated, the “re-transmission request” command is transmitted (step S86), and the process returns to step S77. If the switch is not operated, the trigger 2 switch is in the “ON” state. Is determined (step S87). When the trigger 2 switch is in the ON state, if reception is confirmed, it is determined whether or not there is a sufficient free space (OK) even after data recording on the receiving side memory card (step S88). If it is not OK, an “NG” command is transmitted (step S91), and the process proceeds to step S92. If it is OK, an “OK” command is transmitted to the image transmitting side (step S89). When the trigger 2 switch is not “ON”, it is determined whether or not the right arrow switch 14C has been operated (ON) (step S85). If not, the process returns to step S85. Is deleted (step S96), the process proceeds to step S88.

  Another embodiment of the present invention achieves the same object as the embodiment shown in FIGS. 13 to 15, and manages the designation of a plurality of images by recording a designated file name of DOS management in a control file. By doing so, it is possible to designate a plurality of images without displaying file names on the camera, and to easily and continuously transmit images.

  FIG. 16 is a flowchart for explaining the operation processing procedure of the present embodiment, and shows the program transmission setting processing procedure.

  After entering the transmission mode and starting the reproduction operation (step S101), it is determined whether or not the program mode (DRIVE-P mode) is entered by continuing to press the DRIVE switch 14I for 3 seconds (3S) (step S102). If it is not the program mode, the transmission mode is entered as it is, and if it is the program mode, the setting mode is set (step S103), and it is determined whether or not the right arrow switch 14D is operated (step S104). If it is operated, the next image is reproduced (step S106). If not operated, it is next determined whether or not the left arrow switch 14C is operated (step S105). If it is operated, the previous image is reproduced (step S107). If not operated, it is determined whether the trigger 1 switch 14A is ON as it is. If it is determined that it is not ON, the process returns to step S104, and if it is determined that it is ON, the file name of the image being reproduced is acquired (step S109). Thereafter, it is determined whether or not the trigger 2 switch 14B is ON (step S110). If not ON, the process returns to step S104. If ON, the file name is recorded in the control file (step S111). Enter transmission mode.

  FIG. 17 shows a program transmission processing procedure. First, similarly to FIG. 16, it is determined whether or not the DRIVE-P switch is in the ON (pressed) state for 3 seconds (step S121). The process proceeds to the setting process of FIG. Otherwise, the control file is read (step S122), the file name of the set image is acquired (step S123), and the reproduction operation is performed (step S124). Subsequently, after waiting for the trigger 2 switch 14B to be turned on (step S125), transmission processing is performed (step S126) and the reproduction mode is entered.

  FIG. 18 is a flow chart showing still another embodiment of the present invention. The designation of a plurality of images is made as a directory entry NO. FIG. 4 shows an operation process in which a plurality of images can be specified without recording the file name on the camera by recording and managing in a control file.

  The processing procedure of the first half of the present embodiment is the same as the processing procedure shown in FIG. 16, and when it is determined that the trigger 2 switch 14B is ON, the entry NO. Is recorded in the control file (step S131), and the transmission mode is entered.
