  Hereinafter, an embodiment when the present invention is applied to a digital camera will be described with reference to the drawings.

  FIG. 1 is a diagram showing an external configuration of the digital camera. FIG. 1A is a diagram mainly showing a front configuration, and FIG. 1B is a diagram showing mainly a rear configuration.

  In this digital camera 10, a photographing lens 2 and an optical viewfinder 3 are disposed on the front surface of a substantially short thin plate-like body, and a shutter key 4 and a power key 5 are disposed on the upper surface.

  The photographing lens 2 is, for example, a short focus lens or a zoom lens, the optical finder 3 is a viewing window for confirming a subject, penetrates the camera body, is paired with the optical finder 9, and the power key 5 is The shutter key 4 functions as a key for instructing the release in the shooting mode, while functioning as a key for setting / execution in the menu selection or the like. To do.

  Further, a mode switch (SW) 6, a menu key 7, a cross key 8, an optical viewfinder 9, and a display unit 11 are arranged on the back of the digital camera 10.

  The mode switch 6 is constituted by, for example, a slide switch, and switches between a photographing mode “R”, a reproduction mode “P”, and a schedule data management mode “S”. The menu key 7 is operated when various menus are selected.

  The cross key 8 is a key used for selecting a character when operating various menus, for example, when moving a cursor, or when inputting characters for recording schedule data or inputting a folder name.

  The optical finder 9 is a viewing window for confirming a subject with an object that is paired with the optical finder 3, and the display unit 11 is composed of a color liquid crystal panel with a backlight, and is monitored as an electronic finder in the photographing mode. In the reproduction mode, the selected image is reproduced and displayed, and the captured image data is managed, while in the schedule data management mode, the recorded schedule data is displayed.

  Although not shown, a memory card slot with a lid is provided on the lower surface of the body, and a memory card as a recording medium of the digital camera 10 is detachably mounted.

  FIG. 2 is a block diagram showing the circuit configuration, and 10 is a digital camera. The digital camera 10 can be set by switching between a shooting mode, a playback mode, and a schedule management mode as a basic mode. In the monitoring state in the shooting mode, the focus position and the aperture position are set by driving the motor (M) 21. The CCD 23, which is an image sensor disposed behind the photographing optical axis of the lens optical system 22 to be moved, is scanned and driven by a timing generator (TG) 24 and a vertical driver 25, and corresponds to an optical image formed at regular intervals. A photoelectric conversion output for one frame is output.

  The photoelectric conversion output is appropriately gain-adjusted for each RGB primary color component in the state of an analog value signal, then sampled and held by a sample hold circuit (S / H) 26, and digital data by an A / D converter 27. And output to the color process circuit 28.

  The color process circuit 28 performs color process processing including pixel interpolation processing and γ correction processing on the digital data of the image sent from the A / D converter 27, and outputs a digital luminance signal Y and color difference signals Cb, Cr. And output to a DMA (Direct Memory Access) controller 29.

  The DMA controller 29 once uses the luminance signal Y and the color difference signals Cb and Cr output from the color process circuit 28 by using the composite synchronization signal, the memory write enable signal, and the clock signal from the color process circuit 28 once. And is DMA-transferred and output to a DRAM 31 used as a buffer memory via a DRAM interface (I / F) 30.

  The control unit 32 is composed of a CPU, a ROM storing an operation program, a RAM as a work memory, and the like in order to control the operation of the entire digital camera 10, and DMA the luminance and color difference signals to the DRAM 31. After the transfer is completed, the luminance and color difference signals are read from the DRAM 31 via the DRAM interface 30 and written to the VRAM 34 via the VRAM controller 33.

  The digital video encoder 35 periodically reads the luminance and color difference signals from the VRAM 34 via the VRAM controller 33, generates a video signal based on these data, and outputs the video signal to the display unit 11.

  The display unit 11 includes, for example, a color liquid crystal display panel with a backlight and a driving circuit thereof, and is fixedly disposed on the back side of the main body of the digital camera 10, and a monitor display unit (electronic finder) in the shooting mode. By performing display based on the video signal from the digital video encoder 35, an image based on the image information captured from the VRAM controller 33 by imaging with the CCD 23 at that time is displayed.

  In this way, with the display unit 11 displaying the current image as a monitor image in real time, the shutter key 4 in the plurality of keys constituting the key input unit 36 is operated at the timing at which still image shooting is desired. Then, a trigger signal is generated.

  In response to this trigger signal, the control unit 32 immediately stops the path from the CCD 23 to the DRAM 31 after the DMA transfer to the DRAM 31 of the luminance and color difference signals for one frame captured from the CCD 23 at that time, and records and saves them. Transition to the state.

  In this recording and storage state, the control unit 32 outputs the luminance and color difference signals for one frame written in the DRAM 31 through the DRAM interface 30 to each of Y, Cb, and Cr components of 8 pixels by 8 pixels. A unit called a basic block is read out and written into a JPEG (Joint Photographic Coding Experts Group) circuit 37. The JPEG circuit 37 uses an ADCT (Adaptive Discrete Cosine Transform), an entropy coding system. Data compression is performed by such processing.

  The obtained code data is read out from the JPEG circuit 37 as a data file of one frame, and is written in a flash memory 38 enclosing a flash memory which is a non-volatile memory that is detachably mounted as a recording medium of the digital camera 10. .

  The flash memory 38 is managed by the control unit 32 in a hierarchical file system, and the data is managed so that the data exists in a folder having an arbitrary name as viewed from the user of the apparatus. The

  Then, along with the compression processing of the luminance and color difference signals for one frame and the completion of writing all the compressed data to the flash memory 38, the control unit 32 activates the path from the CCD 23 to the DRAM 31 again.

  In the playback mode, the control unit 32 selectively reads out the image data recorded on the memory card 38, and the JPEG circuit 37 compresses the image data that has been compressed by a procedure completely opposite to the procedure of data compression in the shooting mode. The decompressed image data is stored in the VRAM 34 via the VRAM controller 33, and then periodically read out from the VRAM 34. A video signal is generated based on the image data and reproduced and output on the display unit 11. .

  Note that a key input unit 36 and an RTC 39 are further connected to the control unit 32.

  In addition to the shutter key 4 and the power key 5 described above, the key input unit 36 is a mode switching key for switching between a shooting mode (REC) mode and a playback (PLAY) mode, which are basic modes, and a schedule data management mode for recording and managing schedule data. 6. Menu key 7 for displaying various menu items, selection of images and various detailed modes, specification of menu selection items, selection of characters to be input from a character selection table displayed for character input, etc. The cross key 8 and the like for instructing the up, down, left, and right directions are configured, and signals accompanying the key operations are directly sent to the control unit 32.

  An RTC (Real Time Clock) 39 provides date and time data to the control unit 32 more. This is used as a time stamp in the hierarchical file system or to provide the photographing time to the control unit 32 when the photographed image is written in the flash memory 38.

  In the schedule management mode, the control unit 32 inputs schedule data using the key input unit 36 and stores it in the schedule data storage unit 40.

  FIG. 3 shows an example of character input using the key input unit 36. A character selection table shown in FIG. 3A is displayed on the display unit 11. This character selection table displays characters that can be input in a table format, and the selected characters are displayed in black and white. When inputting black and white reversed characters as a part of a desired character string, the shutter key 4 is pressed.

  When selecting a character other than the selected black / white inverted character, as shown in FIG. 3B, press the cross key 8 corresponding to the direction in which the black / white inverted character is to be moved to move the black / white inversion. When the black / white reversal moves to the desired character, the shutter key 4 is pressed again to input the character. This series of operations is performed to input a desired character string.

  FIG. 4 shows an example of the contents stored in the schedule data storage unit. As shown in FIG. 4, the schedule data is divided into items of “date”, “start time”, “end time”, “subject”, “content”, and “classification”, and each item is set as one set of schedule data. Store in the unit 40. “Date” is the date on which the schedule exists. “Start time” and “End time” are the scheduled start and end times of the schedule, “Subject” is the title of the scheduled schedule, and “Content” is the part that stores information related to the scheduled schedule “Category” is an item used when managing the types of schedules separately. The schedule data is used for schedule management by storing a schedule that exists in the future or the past.

  Next, the operation of the above embodiment will be described.

<Schedule management>
FIG. 5 shows processing contents based on an operation program executed mainly by the control unit 32 in a state where the schedule management mode is selected as the basic mode.

  The user enters the schedule data management mode “S” with the mode switch 6 in advance (step A1), and the device user inputs the date, start time, and end time into the digital camera from the key input of the key input unit 36. Perform (Step A1). Regarding the time, it is possible to memorize even by inputting only the start time. The contents input in step S1 are temporarily stored in the DRAM 31 via the DRAM I / F 30 (step A2).

  Next, a subject is input (step A3). This inputs a character string that briefly represents the contents of the schedule. The contents input in step S3 are temporarily stored in the DRAM 31 via the DRAM I / F 30 (step A4).

  Next, the contents of the schedule are input by the apparatus user (step A5). This is a character string that represents the details of the schedule. The contents input in step S5 are temporarily stored in the DRAM 31 via the DRAM I / F 30 (step A6).

  Next, a schedule classification is input by the apparatus user (step A7). This is an item to be input to classify a plurality of schedule data, such as “business” for a schedule related to work and “personal” for a schedule related to personal contents. The contents input in step S7 are temporarily stored in the DRAM 31 via the DRAM I / F 30 (step A8).

  Next, the data temporarily stored in the DRAM 31 is stored in the flash memory 38 as one schedule data (step A9). Thereafter, this process is terminated.

<Create new folder>
This is a process for creating a folder, which is a data management method using a hierarchical file system for storing and managing image data in advance by a user of the digital camera.

  FIG. 6 shows the processing contents mainly based on the operation program executed by the control unit 32.

  By switching the mode switch 6 by the apparatus user in advance, the playback mode is entered (step B1), and a folder creation screen (not shown) is displayed on the display unit 11.

  Next, when the captured image is stored in the flash memory 38, it has management information separately from the position in the flash memory 38 that is actually stored, and hierarchical data at an arbitrary position as viewed from the apparatus user. A folder that is a data storage location for management is created (step B2).

  The apparatus user inputs a part or all of the subject stored in step A3 as a folder name using the key input unit 36 in the folder created in step B2 (step B3).

  The control unit 32 determines whether to continue to create a folder (step B4). If a plurality of folders are to be continuously created, the operations of steps B2 to B4 are repeated to create a plurality of arbitrary folders. .

  After a desired number of folders are created, a folder for storing captured images that does not correspond to a folder to be classified is created as a result of comparison in the above-mentioned created folder by classification and storage of shooting data (step B5). .

<Comparison classification after shooting>
FIG. 7 shows processing contents based mainly on an operation program executed by the control unit 32 in a state where the photographing mode is selected as the basic mode.

  A switching operation is previously performed by the device user with the mode switch 6 to enter the photographing mode. (Step C1).

  When the shutter key 4 is operated, this is determined in step C2, and a transition is made to a state in which the data file of one frame read out from the JPEG circuit 37 is immediately stored in the flash memory 38. (Step C3).

  At this time, the RTC 39 can be referred to for the date and time when the shutter key is pressed in step C2 (step C4).

  Next, it is determined whether or not schedule data having the same date as the date obtained in step C4 is stored in the schedule data registered in step A9 (step C5). If schedule data of the same date is stored, whether the schedule data of the date and time that is the time between the start time and the end time is stored in the next applicable schedule A determination is made (step C6).

  If it is determined in step C6 that the corresponding schedule data is stored, the subject of the corresponding schedule data is stored in the flash memory 38 as a part of the file name of the photographed image (step C7). Thereafter, it is determined whether the folder created in step B3 including the subject of the schedule data in C7 is stored (step C8). If the corresponding folder is stored, the captured image is stored in the management information so as to be managed in the corresponding folder (step C9).

  On the other hand, if it is determined in step C5 or step C6 that the corresponding schedule data is not stored, a character string predetermined by the digital camera 10, for example, a character string unique to the digital camera 10 such as CIMG2005050410.jpg A number indicating the shooting date and a character string generally used to indicate the type of file called an extension are added and stored in the flash memory 38. Next, the management information is stored so as to be managed without the uncategorized folder created in step B5 (step C11).

  If it is determined in step C8 that the corresponding folder is not stored, the management information is stored so as to be managed without the uncategorized folder created in step B5 (step C11).

  FIG. 8 is a diagram for explaining an example of the present invention. In this example, the schedule data is managed in the digital camera, but the schedule management may be performed by another device such as a PDA or a mobile phone.

  Assume that schedule data as shown in FIG. 4 is stored in advance in the schedule data storage unit. In addition, a folder (D1) having a name to which the subject of the schedule that the user of the digital camera 10 will perform, such as “conference”, “tennis”, and “snowboard”, is created in advance. deep.

  Next, the digital camera 10 performs photographing (D4). It is assumed that when photographing is performed, the date and time is referred to from the RTC 39 in the digital camera 10 and “Dec. 11, 2005, 14:45” (D2) is obtained. Of the date / time data obtained from the RTC 39, a comparison is made as to whether there is the corresponding schedule data on the date part December 11, 2005. In this case, there is schedule data with the subject “strategy meeting”.

  Next, it is compared whether the time 14:45 obtained from the RTC 39 is between the “start time” and “end time” of the schedule data. In this case, 14:45 is between 10:00 and 15:00, so when storing the shooting data in the flash memory 38, the character string “strategy meeting” of the subject schedule data is added as the file name. And stored as “strategy meeting 1211.jpg” (D3). Reference numeral 1211 denotes a number indicating the date, and “.jpg” is generally called an extension, and is a character string used to represent the type of file.

  Next, a comparison is made as to whether a folder with a character string that matches the character string of the subject “strategy meeting” corresponding to the previous one is stored. In this case, since the folder “conference” corresponds, the photographed image data named “strategic conference 1211.jpg” previously stored in the flash memory 38 is assumed to be in the folder “conference”. Store in the management information (D5).

  Similarly, since the shooting data taken at 12:30 on December 12, 2005 corresponds to the schedule data “tennis match” on December 12, 2005, 10:00:00 to 15:00, “tennis match 1212.jpg” And stored in the management information of the management system as being in the folder name “tennis”.

  In this way, schedule data and a folder for file management are created in advance. When image shooting is instructed by operating the shutter key 4, the shooting date / time is acquired from the RTC 39, the shooting date / time is compared with the date / time of the schedule data stored in the schedule data storage unit 40, and Is stored in the flash memory 38 as the file name of the image shooting data, and a comparison is made as to whether a folder including the subject of the schedule data is stored. When a folder is stored, the image shooting data is put in the folder.

  Therefore, it is possible to search for desired photographed image data, for example, when reproducing photographed image data by inferring from the situation of photographing.

  In the above embodiment, the subject of the schedule data is stored as the name of the shooting data, and the folder name is stored in the management information as being in the folder including the subject. However, the present invention is not limited to this. You may memorize | store as additional data of imaging | photography data.

  That is, as shown in FIG. 9, it is assumed that schedule data as shown in FIG. 4 is stored in the schedule data storage unit in advance. In addition, a folder (E1) having a name of the classification name of the schedule that the user of the digital camera 10 will perform, such as “business” and “personal”, is created in advance.

  Next, the digital camera 10 performs photographing (E2). Suppose that the date and time is referred to from the RTC 39 in the digital camera 10 and “December 11, 2005, 14:45” (E3) is obtained when shooting is performed. Of the date / time data obtained from the RTC 39, a comparison is made as to whether there is the corresponding schedule data on the date part December 11, 2005. In this case, schedule data with the subject “strategy meeting” and the classification “business” exists. Next, a comparison is made as to whether the time 14:45 obtained from the RTC 39 is between the “start time” and “end time” of the schedule data. In this case, 14:45 is between 10:00 and 15:00, so when storing the shooting data in the flash memory 38, the character string “strategy meeting” of the subject schedule data is added as the file name. “Strategy meeting 1211.jpg” and additional data such as EXIF is stored as “business” (E4).

  Next, a comparison is made as to whether a folder with a character string that matches the character string of the category name “business” that corresponds to the previous folder is stored. In this case, since the folder “business” corresponds, the photographed image data named “strategy meeting 1211.jpg” previously stored in the flash memory 38 is assumed to be in the folder “meeting”. Store in the management information (E5).

  Similarly, since the shooting data taken at 12:30 on December 12, 2005 corresponds to the schedule data “tennis match” on December 12, 2005, 10:00:00 to 15:00, “tennis match 1212.jpg” Is added to the flash memory 38 and stored in the management information of the management system as being in the folder name “personal”.

  For this reason, since the captured image data can be managed with a larger classification, it is easy to search for desired captured image data when reproducing the captured image data.

  In the above-described embodiment, the folder is classified. However, the present invention is not limited to this, and a management method in which related information is added and stored in the management information when the captured image data is stored in the flash memory 38 is also possible.

  In the above embodiment, the captured image data is used. However, the present invention is not limited to this, and the image acquisition method is a method of downloading from the Internet and storing it in a storage device, copying or pasting an image from a memory connected to a PC. It is also possible to perform it at the timing of acquiring image data stored in another storage device.

  Note that the date comparison is performed in step C5 and the time comparison is performed in step C6. However, the date comparison and the time comparison may be performed in one step.
