BACKGROUND OF THE INVENTION
  The present invention, DeIt relates to digital cameras.
[0002]
[Prior art]
In a digital camera, a subject image is picked up by an image pickup device such as a CCD, converted into digital image data, and recorded in a memory in the camera or a detachable memory card. In recent years, digital cameras that can record sound in relation to a photographed subject image and reproduce the recorded sound are generally provided. With a digital camera having such a voice recording function and a voice playback function, voice recording can be performed on the image immediately after shooting the image, or an image that has already been shot and recorded on the memory card can be played back and recorded. Playback is in progress.
[0003]
When recording audio data in the memory card, the audio file of the data is recorded in association with the image file. When an image is played back on a display monitor provided in the digital camera, if there is an audio file associated with the image, a display indicating that sound is recorded on the monitor, for example, an icon such as a musical note is displayed together with the image. Is displayed.
[0004]
The image file recorded on the memory card can be deleted by operating a camera button or the like. In that case, in order to prevent inadvertent mistaken deletion of the image file, it is common to protect the image file so that it cannot be deleted. For example, if you set protection for a specific image file recorded on a memory card and delete all image files for the purpose of deleting other image files, only the protected image file will not be deleted. Will remain in the memory card.
[0005]
[Problems to be solved by the invention]
However, various settings made for the image file are not applied to the audio file associated with the image file. For this reason, if the protection setting is performed on a specific image file and the entire deletion operation is performed, the protected image file remains, but the sound file is deleted regardless of the protection setting of the image file. .
[0006]
  The purpose of the present invention is toAssociated with an image fileAudio fileIt is hard to generate trouble inTo provide a digital camera.
[0007]

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a digital camera according to the present invention. As shown in FIG. 1, the digital camera according to the present embodiment includes an imaging unit 1 having a CCD imaging device 10 as imaging means, a digital circuit unit 2 centered on a system LSI 20, and an audio circuit unit related to audio recording and reproduction. 3. An image reproduction circuit unit 4 and an operation unit 5 having various operation buttons are provided. In this digital camera, a memory card 6 is detachably provided as a recording device for storing image files and audio files.
[0009]
The CCD image pickup device 10 is an area-type image pickup device in which a plurality of pixels are two-dimensionally arranged, and a subject image is formed on the image pickup surface of the CCD image pickup device 10 by a shooting optical system (not shown). In this embodiment, a CCD type image sensor is described as an example of the image sensor, but a MOS type image sensor or the like may be used. The subject image is photoelectrically converted in the CCD image sensor 10, and an electrical signal corresponding to the subject image is input from the CCD image sensor 10 to the analog signal processing circuit 11.
[0010]
The analog signal processing circuit 11 includes an AGC (stationary gain control circuit), a CDS (correlated double sampling circuit), and the like, and performs analog signal processing such as gain adjustment and noise removal on the input image signal. The image signal subjected to the analog signal processing is converted into a digital signal by the A / D conversion circuit 12 and input to the system LSI 20 of the digital circuit unit 2. A TG (timing generator) circuit 13 outputs an operation timing signal to each of the CCD image pickup device 10, the analog signal processing circuit 11, and the A / D conversion circuit 12, and controls the operation timing therebetween.
[0011]
In the system LSI 20 of the digital circuit unit 2, digital signal processing such as image size change, white balance processing, gamma correction, and data compression processing are performed on the digital image data input from the A / D conversion circuit 12. The ROM 21 constituting the program memory stores programs relating to these processes and a control program for the entire camera. When a power switch (not shown) is turned on, the system LSI 20 executes the control program. The RAM 22 constituting the image memory is used as a buffer memory for temporary storage of image data input from the imaging unit 1, various image processing, and image compression / decompression processing. In addition, audio data recorded by the audio circuit unit 3 and audio data read from the memory card 6 for reproduction by the audio circuit unit 3 are also temporarily stored in the RAM 22.
[0012]
The input audio is converted into an analog audio signal by the microphone 30 of the audio circuit unit 3 and input to the audio processing LSI 31. The analog audio signal input to the audio processing LSI 31 is sampled at a predetermined frequency in the audio processing LSI 31 and converted into digital audio data. The digital audio data is sequentially captured by the system LSI 20 of the digital circuit unit 2 and temporarily stored in the RAM 22. Further, at the time of sound reproduction, sound is output from the speaker 32.
[0013]
The image reproduction circuit unit 4 is provided with a display monitor 40 for displaying a captured image and a reproduced image, and a monitor controller 41 for controlling drive of the display monitor 40. A menu screen for performing various settings is also displayed on the display monitor 40. As the display monitor 40, for example, a TFT-LCD or the like is used. The operation unit 5 is provided with a release button 51, a monitor button 52, a menu button 53, a recording / playback button 54, a setting / release button 55, and a multi selector 56. The multi selector 56 is a multi-function operation button having four arrow buttons 56a to 56d, and is used for display image switching, menu switching at the time of menu operation, item selection, and the like as will be described later.
[0014]
The release button 51 is an operation button for performing a photographing operation. The AF operation and the focus lock are performed by a half-press operation, and image data captured by the CCD image sensor 10 is captured by a full-press operation. The monitor button 52 is an operation button for instructing on / off (display / non-display) of the display monitor 40. When the monitor button 52 is pushed, the display monitor 40 is turned on to enter the display state, and the image of the last recorded file among the image files recorded in the memory card 6 is reproduced and displayed on the display monitor 40.
[0015]
Further, as will be described later, when there is no audio file associated with the image file, when the recording / playback button 54 is pressed, the audio circuit unit 3 performs audio recording, and when there is an audio file, recording / playback is performed. When the button 54 is pressed, sound reproduction by the sound circuit unit 3 is performed. The operation mode of the record / play button 54 may be such that recording / playback is started by the first push operation and recording / playback is stopped by the second push operation. The recording / playback operation may be performed only while the recording is continued. In the present embodiment, the former is called a hold type and the latter is called a non-hold type.
[0016]
<About shooting operation>
When the release button 51 is fully pressed, the image signal of the subject image picked up by the CCD image pickup device 10 is subjected to analog processing such as gain adjustment and noise removal in the analog signal processing circuit 11 and then A / D. The signal is converted into a digital signal by the conversion circuit 5. The digital image data input to the system LSI 20 is temporarily stored in the RAM 22. Thereafter, image data is read from the RAM 22 to the system LSI 20, subjected to image preprocessing such as white balance adjustment, contour enhancement, and gamma correction, and then stored in the RAM 22 again. The image data temporarily stored in the RAM 22 is then compressed into the memory card 6 or recorded without being compressed.
[0017]
<Recording / audio playback operation>
Next, recording to an image recorded in the memory card 6 and reproduction operation of audio data recorded in association with the image will be described with reference to the flowcharts of FIGS. 2 and 3 and the block diagram of FIG. The operation of the record / play button 54 will be described as a non-hold type in which a record / play operation is performed only while it is depressed.
[0018]
When the monitor button 52 is pressed in step S101, the process proceeds to step S102 to search for an image file recorded on the memory card 6. In step S103, it is determined whether there is an image file in the memory card 6. If it is determined that there is an image file, the process proceeds to step S104. If it is determined that there is no image file, a series of recording / playback operations is terminated. To do.
[0019]
In step S104, the last recorded image file in the memory card 6 is read, and the image is reproduced and displayed on the display monitor 40. At this time, if the data of the read image file is compressed data, the data is decompressed by the system LSI 20 of FIG. This image data is read again from the RAM 22, changed to an image size that matches the number of display pixels of the display monitor 40, and stored in the reproduction display area in the RAM 22. The reproduction display data stored in the reproduction display area is read into the system LSI 20, converted into an analog video signal such as RGB, and then displayed on the display monitor 40 as a photographing result.
[0020]
In step S104, when the audio file associated with the image displayed on the display monitor 40 is recorded in the memory card 6, the audio mark 42 is displayed on the display monitor 40 together with the image. 4A and 4B are diagrams showing display examples. FIG. 4A shows an image display when there is no audio file, and FIG. 4B shows an image display when there is an audio file. In FIG. 4B, an audio mark 42 indicating that there is an audio file associated with the image is displayed at the upper left of the screen.
[0021]
In step S105, the reproduction time is started. In step S106, it is determined whether or not a predetermined reproduction time has elapsed. If it is determined in step S106 that the predetermined reproduction time has elapsed, the process proceeds to step S107 to end the image reproduction on the display monitor 40, that is, the display monitor 40 is turned off and the series of operations is ended. On the other hand, if it is determined in step S106 that the time has not elapsed, the process proceeds to step S108.
[0022]
In step S108, it is determined whether or not the monitor button 52 has been pushed during image reproduction. If it is determined that the monitor button 52 has been pushed, the process proceeds to step S107. If it is determined that the monitor button 52 has not been pushed, the process proceeds to step S109 in FIG. In step S109, it is determined whether recording or audio playback is in progress. If it is determined in step S109 that recording / playback is in progress, the process proceeds to step S110. If it is determined that recording / playback is not in progress, the process proceeds to step S113. Note that “recording” means that the recording operation is performed from the time when the voice is captured by the microphone 30 until the voice data is stored in the RAM 22.
[0023]
When the process proceeds from step S109 to step S110, it is determined whether or not the recording limit time (recording limit) has been reached in step S110, or whether all the audio data has been reproduced (reproduction end). If it is determined in step S110 that the recording limit or playback has ended, the process proceeds to step S112. If it is determined that the recording limit or playback has not ended, the process proceeds to step S111.
[0024]
In a succeeding step S111, it is determined whether or not the recording / playback button 54 is released. If it is determined in step S111 that the recording has been canceled, the process proceeds to step S112 to stop recording / playback. If it is determined that the recording / playback has not been canceled, the process returns to step S109. If the operation mode of the record / play button 54 is the hold type, it is determined in step S111 whether the record / play button 54 has been pressed again.
[0025]
In step S113, it is determined whether or not the display image switching operation has been performed by operating the multi selector 56 of FIG. In a state where an image is being reproduced on the display monitor 40, the image is switched in the order of shooting every time the button 56b or 56d of the multi-selector 56 is pressed, and what is the order of shooting every time the button 56a or 56c is pressed. Images are switched in the reverse order. If it is determined in step S113 that there is no image switching, the process proceeds to step S114. If it is determined that image switching has been performed, the process returns to step S104, and the next or previous image data displayed on the display monitor 40 is stored in the memory card. 6, the image is reproduced and displayed on the display monitor 40.
[0026]
In step S114, it is determined whether or not there is an audio file associated with the displayed image. In the case of the image shown in FIG. 4B, it is determined that it exists, and the process proceeds to step S115, and FIG. In the case of the image shown in FIG. In step S115, it is determined whether or not reproduction is instructed by pressing the audio reproduction button 55. If it is determined in step S115 that the button has been pressed, the process proceeds to step S116 to start reproduction. If it is determined that the button has not been pressed, the process returns to step S106 in FIG.
[0027]
At the time of audio reproduction, the audio data recorded on the memory card 6 is once read into the RAM 22, and then the audio circuit unit 3 is operated in the reproduction mode, and the audio data on the RAM 22 is sequentially sent to the audio processing LSI 31. The digital audio signal is converted into an analog audio signal by the audio processing LSI 31 and reproduced by the speaker 32.
[0028]
On the other hand, if the process proceeds from step S114 to step S117, it is determined whether or not the record / play button 54 has been pressed. If it is determined in step S117 that the button has been pressed, the process proceeds to step S118 to start recording. During recording, the audio circuit unit 3 is operated in the recording mode, and an analog signal input from the microphone 30 is sampled at a predetermined sampling frequency by the audio processing LSI 31 and converted to digital data. The data is taken into the system LSI 20 and temporarily stored in the RAM 22 and then recorded in the memory card 6 in association with the image file.
[0029]
If it is determined in step S117 that the button has not been pressed, the process returns to step S106 in FIG. When the record / reproduction button 54 is not pressed, the image reproduction display is performed until a predetermined image reproduction time elapses or the monitor button 52 is pressed again. Note that when the recording or reproduction is started in steps S116 and S118, the time measurement of the image reproduction time may be restarted.
[0030]

[0032]
In step S203, it is determined whether or not the multi-selector 56 has been operated. If it is determined that the multi-selector 56 has been operated, the process proceeds to step S206. If it is determined that the multi-selector 56 has not been operated, the process proceeds to step S204. In step S204, it is determined whether or not a predetermined reproduction time has elapsed as in step S106. If it is determined in step S204 that the predetermined playback time has elapsed, the process proceeds to step 205, where the playback menu processing is ended, the display monitor 40 is turned off, and the series of processing ends. If it is determined in step S204 that the predetermined reproduction time has not elapsed, the process returns to step S203.
[0033]
On the other hand, when the process proceeds from step S203 to step S206, it is determined whether or not the buttons 56a and 56b of the multi-selector 56 are pressed in step S206. If it is determined in step S206 that the buttons 56a and 56b have been pressed, that is, if it is determined that a cursor movement operation has been performed, the process proceeds to step S210, the cursor 404 is moved up or down, and the process returns to step S203. If it is determined in step S206 that the buttons 56a and 56b are not pressed, the process proceeds to step S207.
[0034]
In step S207, it is determined whether or not the button 56c of the multi-selector 56 has been pressed. If it is determined that the button 56c has been pressed, the process proceeds to step S211. If it is determined that the button 56c has not been pressed, the process proceeds to step S208. When the process proceeds from step S207 to step S211, a menu switching screen on which menu items such as a playback menu, a shooting menu, a setup menu, and a custom setting menu are displayed on the display monitor 40, and switching to each menu is performed. Make it possible.
[0035]
When a menu item other than the playback menu is selected in this state, the processing of the playback menu in FIG. 5 is terminated and the processing is switched to the processing of the selected menu. Here, processing in the playback menu will be described, and description of other menu processing will be omitted. That is, if there is no switching operation to another menu in step S211, the process returns from step S211 to step S203.
[0036]
On the other hand, when the process proceeds from step S207 to step S208, it is determined whether or not the button 56d has been pressed in step S208, that is, whether or not the item for which the cursor 404 in FIG. judge. If it is determined in step S208 that the button 56d has been pressed, the process proceeds to step S212. If it is determined that the button 56d has not been pressed, the process proceeds to step S209. In step S209, it is determined whether or not the menu button 53 has been pressed. If it is determined that the menu button 53 has been pressed, the process proceeds to step S205. If it is determined that the menu button 53 has not been pressed, the process returns to step S203. On the other hand, when the process proceeds from step S208 to step 212, the setting process of the item selected by the cursor 404 in FIG. 6A is performed, and then the process returns to step S203.
[0037]
The item setting process in step S212 will be described below with respect to protection. FIG. 7 is a flowchart showing the protect item setting process. In step S301, image data for six frames is read from the memory card 6 and a thumbnail image for each image data is created. In step S302, the created thumbnail image is displayed as a thumbnail on the display monitor 40. FIG. 6B shows a thumbnail display 405, in which six frames A to F are displayed. In image B, an image selection cursor 406 is displayed.
[0038]
In step S303, the buttons 56a and 56b of the multi-selector 56 are operated, and the cursor 406 is moved to an image to be protected and an image is selected. In step S304, it is determined whether or not protection is set for the selected image. If it is determined in step S304 that protection is not set, the process proceeds to step S305. When the set / cancel button 55 is pressed in step S305, protection is set for the image file of the image selected by the cursor 405. For example, a read-only setting flag of the DOS system is set in the header of the image file.
[0039]
As shown in FIG. 6C, a protect mark 407 indicating that protection is set is displayed on the thumbnail image B of the display monitor 40. In step S306, it is determined whether an audio file associated with the selected image B is recorded in the memory card 6. If it is determined in step S306 that there is an audio file, the process proceeds to step S307, and the corresponding audio file is also protected. On the other hand, if it is determined in step S306 that there is no audio file, the process proceeds to step S311.
[0040]
On the other hand, if it is determined in step S304 that the protection setting has already been made, the process proceeds from step S304 to step S308. When the set / cancel button 55 is pressed in step S308, the protection of the image file of the image selected with the cursor 405 is cancelled. In step S309, it is determined whether or not an audio file associated with the selected image B is recorded in the memory card 6. If it is determined in step S309 that there is an audio file, the process advances to step S310 to cancel the protection of the corresponding audio file. On the other hand, if it is determined in step S309 that there is no audio file, the process proceeds to step S311.
[0041]
In step S311, it is determined whether or not the button 56c of the multi-selector 56 has been pressed. If it is determined in step S311 that the button 56c has been pressed, the process proceeds to step S312 to display the reproduction menu screen of FIG. 6A and end the series of protect item setting processing, and then to step S203 of FIG. Return. On the other hand, if it is determined in step S311 that the button 56c has not been pressed, the process returns to step S303. By repeating the processing from step S303 to step S311 in FIG. 7, it is possible to sequentially set and release protection for a plurality of images.
[0042]
FIG. 8A schematically shows an image file and an audio file recorded on the memory card 6. In FIG. 8A, “DSC 0001.JPG” to “DSC 0004.JPG” represent image files, and “SND 0001.WAV” to “SND 0003.WAV” represent audio files. The audio files “SND 0001.WAV”, “SND 0002.WAV”, “SND 0003.WAV” are associated with the image files “DSC 0001.JPG”, “DSC 0002.JPG”, “DSC 0003.JPG”, respectively. Yes.
[0043]
In FIG. 8 (a), the image files “DSC 0002.JPG” and “DSC 0003.JPG” and the sound files “SND 0002.WAV” and “SND 0003.WAV” associated with the image files are protected. Is set. In FIG. 8, the mark 601 indicated by “*” indicates that the file is protected. In the protect setting state as shown in FIG. 8A, if all deletion operations are performed for the purpose of deleting an image other than the protected image, the file “DSC 0002. Only “JPG”, “DSC 0001.JPG”, “SND 0002.WAV”, and “SND 0003.WAV” remain.
[0044]
Thus, in this embodiment, when protection is set for an image displayed on the display monitor 40, protection is set not only for the image file but also for the audio file associated with the image file. Therefore, it is possible to prevent the audio file associated with the image file to be saved from being inadvertently deleted. Also, when processing is performed by transferring image files and sound files in the memory card 6 to a personal computer or the like, the read-only setting of the DOS system is set not only for the image files but also for the sound files. Therefore, even when a file operation is performed on a device other than a digital camera, it is difficult to cause a problem that an audio file is accidentally deleted.
[0045]
In the embodiment described above, the protect setting has been described as an example. However, the present invention can be similarly applied to a non-display setting (a DOS file system non-display setting), a setting related to deletion, and the like. Further, when the same setting is made for the image file and the audio file, and the setting is changed / corrected, the same change / correction operation is performed for both files. For example, when canceling the setting with the above-described protect setting, a canceling operation similar to the canceling operation performed on the image file is also performed on the audio file.
[0046]
Further, when the image file and the audio file are recorded as independent files as shown in FIG. 8, the deletion setting (setting to allow overwriting of other data) is performed as described above for the deletion operation. You may make it correspond, and you may perform a substantial data deletion operation | movement to an image file and an audio | voice file. As another example of performing the same file operation in this way, there is transfer of an image file to an external device. In this case, the audio file associated with the image file is also automatically transferred. File operations such as file attribute setting and transfer as described above are performed by the system LSI 20.
