Description

The present invention relates to an imaging equipment, relates to an imaging equipment capable particular format of the mounted recording medium.

  In recent years, electronic devices that can use removable recording media such as digital cameras have increased. In the case of a digital camera, a configuration in which a captured image or recorded sound is recorded on a recording medium as a data file is generally used. For this reason, when the installed recording medium runs out of free space, it is necessary to erase the already recorded data file in order to perform recording using the recording medium. There are usually provided a method of selectively erasing and a method of collectively erasing, and a function of formatting (initializing) a recording medium as a means for erasing all files at once is installed.

  Formatting is a process that cannot usually be undone, and if executed incorrectly, all files are lost, so it is common to prompt for confirmation or warning during execution. For example, in Non-Patent Document 1, in the format function installed in a digital camera, the data size currently in use is written together with the total capacity of the recording medium, and when the format is executed, the displayed amount of data is deleted. It has been shown to call attention to.

“Canon Digital Camera PowerShot A95 Camera User's Guide”, 2004, p.20

  In the above-described technology, the user can understand the data size currently in use on the recording medium. For example, a device that can generate different types of data files such as still images, moving images, and audio, such as a digital camera. However, information for each file type could not be obtained.

  There are devices having a plurality of browse modes corresponding to file types, such as a mode for browsing images such as still images and moving images, and a mode for browsing only audio. When formatting a recording medium in such a device, the user cannot know the data amount and the number of files of the type of file browsed only in a mode different from the current mode. For example, in a device having an image browsing mode and an audio browsing mode, when formatting a recording medium during the image browsing mode, the recording medium is formatted without knowing the total number of audio files. That is, all files including the audio file are deleted without knowing the data amount and the number of files of the audio file.

The present invention has been made to solve such a problem, and in an imaging apparatus capable of formatting a mounted recording medium, the present invention is to present more detailed information to the user before formatting. The purpose is to make it possible.

This object is a recording medium is removable, an imaging apparatus capable of formatting the loaded recording medium, among the files recorded on the loaded recording medium, the total number of files in the first type First detection means for detecting the first detection means, second detection means for detecting the total number of files of the second type among files recorded on the recording medium, and first detection means detected by the first detection means . Storage means for storing the total number of files of the second type and the total number of files of the second type detected by the second detection means, and a menu screen for formatting before executing the formatting process of the recording medium. a display means for displaying, in menu screen the total number of first type of file and the second type of the files stored in the storage means, together with information indicating the type of file Display means possess for the first detection means detects the total number of files of the type first power source in response to it is turned on the imaging apparatus, the second detection means, the menu display means This is achieved by an imaging device that detects the total number of files of the second type when displaying a screen .

With such a configuration, according to the present invention, in an imaging apparatus capable of formatting a mounted recording medium, it becomes possible to present more detailed information to the user before the formatting is executed.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing a configuration example of a digital camera as an embodiment of an imaging apparatus according to the present invention.
In FIG. 1, a digital camera 100 includes an optical system 21 including a photographing lens, an imaging unit 22 that converts an optical image into an electric signal, and an A / D converter 23 that converts an analog signal into a digital signal. The A / D converter 23 is used when converting an analog signal output from the imaging unit 22 and an analog signal output from the audio control unit 11 into a digital signal.

  The timing generation circuit 12 supplies a clock signal and a control signal to the imaging unit 22, the audio control unit 11, the A / D converter 23, and the D / A converter 13. The timing generation circuit 12 is controlled by the memory control circuit 15 and the system control unit 17. The image processing circuit 24 performs predetermined pixel interpolation processing and color conversion processing on the data from the A / D converter 23 or the data from the memory control circuit 15.

  In the image processing circuit 24, the system control unit 17 performs calculations for performing TTL (through-the-lens) AF (autofocus) processing, AE (automatic exposure) processing, and EF (flash preflash) processing. Processing is performed on the captured image data. Further, the image processing circuit 24 performs predetermined arithmetic processing using the captured image data, and also performs TTL AWB (auto white balance) processing based on the obtained arithmetic result.

The output data of the A / D converter 23 is written into the memory 32 via both the image processing circuit 24 and the memory control circuit 15 or only the memory control circuit 15.
The memory 32 is provided to store captured still image data and moving image data, and a file header when an image file is configured from these data, and stores a predetermined number of still images and a predetermined time of moving images. With sufficient storage capacity.

The compression / decompression circuit 16 compresses / decompresses still image / moving image data using a compression encoding method using adaptive discrete cosine transform (ADCT) or the like. The compression / decompression circuit 16 reads the captured image stored in the memory 32 using the shutter 25 as a trigger, performs compression processing, and writes the processed data in the memory 32.
Further, the compressed image read into the memory 32 from the recording unit 19 or the like is read and decompressed, and the processed data is written into the memory 32.

The image data written in the memory 32 by the compression / decompression circuit 16 is converted into a data file in the file unit 20 of the system control unit 17 and recorded on the recording medium 200 via the interface 18.
The memory 32 is also used as an image display memory. The display image data written in the memory 32 is displayed on the image display unit 14 including an LCD or the like via the D / A converter 13.

  The audio signal output from the microphone 10 is converted into a digital signal by the A / D conversion unit 23 via the audio control unit 11 configured by an amplifier or the like, and then stored in the memory 32 by the memory control unit 15.

  The audio data stored in the memory 32 is converted into a data file in the file unit 20 of the system control unit 17 and recorded on the recording medium 200 via the interface 18. On the other hand, the audio file recorded on the recording medium 200 is read into the memory 32 and then converted into an analog signal via the D / A converter 13. Then, the signal controlled by the sound control unit 11 is generated by the speaker 39.

  The system control unit 17 is, for example, a CPU, and controls the entire digital camera 100 by executing a control program recorded in a ROM or memory 31 (not shown). The memory 31 is a memory that stores constants, variables, programs, and the like for operation of the system control unit 17.

  The operation unit 25 is provided as an input means for the user to input an instruction to the digital camera 100, and includes an erase button, a menu button, a SET (select / execute) button, four direction keys arranged in a cross, and the like. Composed.

  When the menu button is pressed, a menu screen on which various settings can be made is displayed on the image display unit 14. The user can make various settings intuitively by moving, selecting, and setting the menu screen displayed on the image display unit 14 using the direction keys and the SET button.

  The shutter button 26 has, for example, a switch that is turned on in a half-pressed state and a switch that is turned on in a fully-pressed state, and is used as a trigger for starting AF and AE processing and a trigger for starting shooting.

  The mode switch 27 is a switch for the user to switch the operation mode of the digital camera 100 (system control unit 17) among a shooting mode, an image playback mode, an audio recording / playback mode, and the like.

  The power supply control unit 30 includes a battery detection circuit, a DC-DC converter, a switch circuit that switches blocks to be energized, and the like. The power supply control unit 30 detects the presence / absence of a battery, the type of battery, and the remaining battery level, controls the DC-DC converter based on the detection result and an instruction from the system control unit 17, and requires a necessary voltage. It supplies to each part including a recording part 19 for a period.

  The power source 28 includes a primary battery such as an alkaline battery or a lithium battery, a secondary battery such as a NiCd battery, a NiMH battery, or a Li battery, an AC adapter, and the like, and is attached to the digital camera 100 via connectors 33 and 34.

  The interface 18 is a camera side interface with a recording medium 200 such as a memory card or a hard disk. The recording medium 200 is connected to the camera 100 via connectors 35 and 36. Reference numeral 35 denotes a connector for connecting to a recording medium such as a memory card or a hard disk, and the recording medium attachment / detachment detection unit 38 detects whether the recording medium 200 is attached to the connector 35.

  The recording medium 200 includes a memory card, a hard disk, and the like. The recording medium 200 includes a recording unit 19 composed of a semiconductor memory, a magnetic disk, and the like, an interface 37 with the camera 100, and a connector 36 that fits with the connector 35 on the camera side.

  FIG. 2 is a diagram illustrating an example of a data structure when the digital camera 100 according to the present embodiment records various data on the recording medium 200. The digital camera 100 of this embodiment records a data file according to a hierarchical directory structure. The image data is stored under the IMAGE directory 201 directly under the ROOT directory 220. A directory number and a file number are assigned to directories below the IMAGE directory 201 based on a unique number counted up for each shooting.

  For example, directory numbers are issued sequentially from 100, and a 100 IMAGE directory 202 is created based on the directory numbers. In the 100IMAGE directory 202, an image file having a file name assigned with a file number that is further counted up from 1 is recorded.

  For example, the name is IMG_0001. JPG (203) and IMG_0002. A file called JPG (204) is generated and recorded at the time of shooting. One IMAGE directory stores up to 100 image files. For example, in the 100 IMAGE directory 202, IMG — 0100. Up to JPG (205) is stored. For the 101st and subsequent shots, a 101IMAGE directory 206 is newly created, and IMG — 0101. A new file 207 called JPG is created. Similar to the 100 IMAGE directory 202, the 101 IMAGE directory 206 also generates and records image files having names using numbers that increase by one (208, 209, 210).

On the other hand, the sound data is recorded in a SOUND directory 211 that is different from the image immediately below the ROOT directory 220.
Similarly to the image data directory and file, the directory name and file name for storing the audio data are also generated using names including numbers that are incremented by one.

  Here, it is assumed that names are generated using numbers that are incremented by 1 from 100 for the SOUND directory and 1 (0001) for the audio data file. Therefore, first, a 100 SOUND directory 212 is created, and a file having a name including 0001, 0002,... Is generated and recorded in the directory every time voice recording is performed. For example, the audio file name is SDR_0001. WAV (213), SDR_0002. WAV (214).

● <Initial operation>
An initial operation of the digital camera 100 to which the recording medium 200 having the file configuration shown in FIG. 2 is mounted will be described with reference to the flowchart of FIG. This process is performed when main power is turned on such as battery replacement or when the storage medium 200 is attached.

First, the system control unit 17 initializes flags, control variables, and the like in the memory 31 (S601).
The system control unit 17 detects the set position of the mode change switch 27, and if the mode change switch 27 is set to power OFF (S603), the power control unit 30 shuts off unnecessary power for each part of the digital camera 100. After performing a predetermined end process such as (S604), the process returns to S603.

  If the mode changeover switch 27 is not in the power OFF mode (S603), the system control unit 17 causes the power supply control unit 30 to determine whether the remaining capacity and operation status of the power supply 28 configured by a battery or the like are problematic in the operation of the digital camera 100. It is determined whether or not there is a problem (S605). If there is a problem, a predetermined warning is displayed using the image display unit 14 (S606), and the process returns to S603.

  If there is no problem with the power supply 28 (S605), the system control unit 17 determines whether the operation state of the recording medium 200 has a problem with the operation of the digital camera 100, particularly with respect to the recording / reproducing operation of the image data with respect to the recording medium. If there is a problem (S607), a predetermined warning display is performed using the image display unit 14 (S606), and the process returns to S603.

  If there is no problem in the operation state of the recording medium 200 (S607), the file management unit 29 obtains the total number of image files recorded in the image directory (IMGAE directory) 201 or less recorded in the recording medium 200. (S608). The acquisition processing of the total number of image files will be described in detail later.

  After acquiring the total number of image files, the system control unit 17 determines the position of the mode changeover switch 27 again. In the case of the shooting mode, the system control unit 17 shifts to the shooting mode (S611). In the case of the voice mode, the mode changes to the voice mode (S612). When transitioning to the voice mode, the process of obtaining the total number of voice files is performed thereafter (S613).

● <Image file total number acquisition processing>
Next, the image file total number acquisition processing performed in S608 of FIG. 6 will be described using the flowchart shown in FIG.
This process is performed by the file management unit 29 as a file total number detecting unit. The file management unit 29 scans the entry of the ROOT directory 220 of the recording medium 200 (S701). If the IMAGE directory 201 is not found there (S702), the process ends.

  If the IMAGE directory 201 exists as a result of the entry scan of the ROOT directory 220 (S701), the entry of the IMAGE directory 201 is scanned (S703). If no file entry is found as a result of this entry scan (S704), the process ends.

  If a file entry exists in the IMAGE directory 201 (S704), if the entry is not a directory, or if the directory is not in a format (numerical value + “IMAGE”) as in 100IMAGE (202) (S705), an entry scan of the IMAGE directory Return to (S703).

  If it is determined in S705 that the target file entry is an image storage directory having a predetermined format, the entry of that directory, for example, the 100IMAGE (202) directory is scanned (S706). As a result, when there is no file entry (S707), the process returns to the entry scan process (S703) of the IMAGE directory 201.

  If there is an entry in S707, in S708, the target entry is a file and the file name is a format for an image file, such as IMG — 0001. It is confirmed whether it is like JPG (203). If the file name matches the image file format, it is recognized as an image file, and the number of image files is incremented (S709). The number of image files is stored in the memory 31 (S710), and the process returns to the entry scan process of the 100IMAGE directory 202 (S706).

The entry is not a file or the file name is, for example, IMG — 0001. If the format is not JPG (203) (S708), the process returns to the entry scan process (S706) of the 100IMAGE directory 202. In this way, for example, the entry scan in the 100IMAGE directory 202 is repeated until there are no more entries.
Finally, when all entries in the IMAGE directory 201 are scanned, there are no more entries (S704), and this process is terminated.

The audio file total number acquisition process (S613) executed when the digital camera 100 transitions to the audio mode can also be acquired in the same manner as the image file total number.
That is, as described above, the audio file is stored under the SOUND directory 211 that exists in parallel with the IMAGE directory 201 under the ROOT directory 220. Therefore, in the above-described flowchart for acquiring the total number of image files, the total number of audio files can be acquired by changing the entry scanning directory and the file name determination condition (file name format) for audio files. is there.

  The total number of acquired audio files is stored in the memory 31 by the file management unit 29 in the same manner as the total number of image files.

● <Recording medium format menu screen generation process>
Next, an operation when the digital camera 100 displays the format menu screen of the recording medium 200 in the shooting mode S611 or the playback mode S610 will be described with reference to FIGS.

FIG. 4 is a diagram showing an example of screen processing in response to an operation of a format processing screen displayed by the digital camera and menu buttons, direction keys, and SET buttons included in the operation unit.
When the menu button of the operation unit 25 is pressed, the system control unit 17 creates menu display data in the memory 32 and displays the data on the image display unit 14. A screen 400 in FIG. 4 shows an example of an initial menu screen displayed by pressing a menu button.

  On such a menu screen, the user can display an individual menu by selecting a desired item using the up and down keys of the direction key and pressing the SET button. Here, when “card initialization” is selected and the SET button is pressed, the system control unit 17 creates an initialization menu screen 450 and displays it on the image display unit 14.

FIG. 3 is a flowchart for explaining processing performed by the system control unit 17 when displaying the format menu screen of the recording medium.
The system control unit 17 acquires management information from a predetermined area of the recording medium 200, and acquires the total capacity of the recording medium 200 from the management information (S309). Further, the free capacity of the recording medium 200 is acquired from the management information (S310). Then, the free space acquired in S310 is subtracted from the total capacity acquired in S309 to calculate the usage amount of the recording medium (S311). If the usage amount is included as management information, the usage amount may be acquired directly from the management information.

  Subsequently, the number of image files stored in the memory 31 is acquired (S301), and it is determined whether or not the number of audio files has been acquired with reference to the memory 31 (S302). If the number of audio files has not been acquired, the recording medium 200 is scanned as described above to acquire the total number of audio files (S303), and the acquired value is stored in the memory 31 (S304).

  In step S <b> 305, the system control unit 17 acquires the total number of audio files stored in the memory 31. A format menu screen is created using each piece of information thus obtained and displayed on the image display unit 14 (S306).

  Thus, in this embodiment, the total number of audio files is acquired only when necessary, such as when creating a format menu screen or in the audio mode. For this reason, the activation process and the subsequent operation in the shooting mode S611 and the reproduction mode S610, which are normal applications, are not delayed by the acquisition of the number of audio files. Further, since the total number of files once acquired is stored in the memory 31, it is not necessary to scan the directory of the recording medium 200 unless the number of files changes. Therefore, from this point as well, it is possible to suppress the occurrence of operation delay due to the file number acquisition.

FIG. 4 shows an example of the format menu screen 450 in the present embodiment.
In the format menu screen 450, 401 is the total capacity of the recording medium 200, 406 is the current usage of the recording medium 200, 407 is the total capacity and a status bar that visually represents the current usage, and 404 is an image file. 405 indicates the total number of images, 402 indicates an icon indicating an audio file, and 403 indicates the total number of audio files.

  As described above, the icons 402 and 404 as information indicating the file type and the corresponding file total number 403 and 405 are displayed side by side, thereby clearly grasping the association between the file type existing in the recording medium 200 and the total number. it can. For this reason, when the format process is executed, it is possible to call the user's attention about what type of data file is deleted and how much.

  In the format menu screen 450, the “cancel” button is selected by default to prevent erroneous execution designation. When the right direction key 409 is pressed in this state, the system control unit 17 moves the selection state (focus) from the “cancel” button to the “OK” button (screen 410). When the SET button 429 is pressed in the state of the screen 410, a formatting operation for writing management area initialization data to the recording medium is started.

  At this time, the system control unit 17 creates a screen 430 including a progress bar 431 indicating the progress of the formatting process and displays it on the screen display unit 14. At this time, the state of the progress bar 431 is sequentially updated as the processing progresses.

  When the formatting operation for the recording medium 200 is completed, the system control unit displays the upper menu 400 again to notify the completion of the formatting operation.

  When the up direction key 419 is pressed on the format menu screen 450, the system control unit 17 moves the focus to the total number of audio files (screen 420). Also, triangular icons are displayed on the left and right of the total number of audio files, and the user is notified that the total number of audio files to be deleted can be changed with the left and right direction keys.

  Further, the system control unit 17 displays an ID 421 in which a directory number (“100” of 100 SOUND) matching the number of audio files and a file number (“0050”) are combined with a hyphen.

  Further, a guidance 422 indicating “SET playback” is displayed below the number, and a display informing the user that when the SET button is pressed in this state, a file whose name is ID indicated by 421 is played back. I do.

  When the SET button 439 is pressed in this state, the file currently indicated by the ID 421 is read from the recording medium 200 into the memory 32, and the audio signal analog-converted by the D / A converter 13 is controlled by the audio control circuit 11 and the speaker. 39 is pronounced (screen 440).

  While the audio file corresponding to the ID 421 is being reproduced, the guidance below the audio file number display 403 is “SET stop” 441 to notify the user that the audio reproduction operation can be stopped with the SET button. When the SET button is pressed in this state, the audio reproduction is stopped.

  In this way, by using the total number of audio files 403 displayed on the format menu screen 450 and further realizing the reproduction operation of the files stored in the recording medium 200, the data to be erased is confirmed before the format execution. It becomes possible.

● <Total file update processing>
Next, update processing of the total number of files accompanying the file operation processing in the digital camera 100 activated in either the shooting mode S611 or the playback mode S610 will be described with reference to the flowchart of FIG.

  This process is executed when the system control unit 17 executes file generation and deletion. The system control unit 17 detects that the delete button included in the operation unit 25 is pressed (or presses the SET button that instructs execution of deletion), and deletes the designated image file or detects that the shutter button 26 is fully pressed. Then, shoot and create a new image file. Then, when image generation or deletion is executed, this is notified to the file management unit 29 as an event.

  First, the file management unit 29 serving as a file total number updating unit monitors an event (S501), and upon receiving a new image creation event notification (S502), reads an image counter (for example, the total number of image files stored in the memory 31 in advance). The value of the set variable is incremented by 1 (S503). Then, the total number of image files held in the memory 31 is updated with the value of the image counter (S504).

  When an image deletion notification is received (S506), the image counter is decremented by 1 (S505), and the total number of image files held in the memory 31 is updated with the value of the image counter (S504).

  Similarly, when a new audio file creation event is detected (S507), the audio counter is incremented by 1 (S508), and the total number of audio files held in the memory 31 is updated with the value of the audio counter (S510). . When the audio file is deleted (S511), the audio counter is decremented by 1 (S509), and the total number of audio files held in the memory 31 is updated with the value of the audio counter (S510).

When the event handler of the file management unit 29 receives a stop command from the system control unit 17 (S512), the operation ends.
As described above, according to the present embodiment, since the number of files existing in the recording medium is presented to the user for each type, the user can set the number of files to be erased by the format execution before the format execution and You can know for each file type.

  In addition, the total number acquisition process for each file type recorded in the recording medium 200 is performed only once per file type and stored, and thereafter, the number of files is updated by detecting operations such as new creation or deletion of the target file. . As a result, even when the total number for each current file type is required when the format menu screen 450 is generated, it is not necessary to rescan the recording medium 200 each time. Therefore, it becomes possible to provide the user with more detailed information than before without impairing the operability of the digital camera 100.
