Specifically, it is realized by a wired / wireless communication device such as a modem or a wireless LAN card, a connection terminal of a communication cable, and a driver circuit thereof. In FIG. 1, the communication terminal 1019 corresponds to this.

  The CPU 10 reads the various programs and data stored in the ROM 30 and the storage medium 72, and performs arithmetic processing while using the RAM 20 as a temporary storage area, thereby controlling the functional blocks and integrating the digital camera 1000. To control.

  FIG. 3A is a diagram showing an example of the configuration of the storage area of the RAM 20 in the present embodiment. As shown in the figure, in the RAM 20 in this embodiment, a user identifier storage area 21R for storing a user identification result based on a physical feature amount, and a retouch processing data storage for storing image processing data at the time of the retouch processing. Region 22R.

  FIGS. 3B and 3C are diagrams illustrating an example of information stored in the ROM 30 in the present embodiment. As shown in FIG. 4B, the ROM 30 in the present embodiment includes a system program 31, a user identification program 32, a shooting tendency storage control program 33, a shooting tendency display control program 34, a script editing program 35, A retouch control program 36, a retouch program group 37, script information 38, and a priority setting TBL 39 are stored.

  The system program 31 is a program for realizing basic functions as a digital camera. The CPU 10 reads and executes the system program 31 to, for example, start processing for performing various initial settings, hardware inspection and loading of necessary programs, white balance and various shooting mode setting processing, exposure measurement, and the like. Processing, shutter speed and aperture control processing according to exposure measurement results, AF control processing, image data creation processing of an image taken when the shutter is released, image storage processing in the storage medium 72, The management process of the image memorize | stored in the storage medium 72, the reproduction | regeneration display process of the image memorize | stored in the storage medium 72, the display control process of various menu screens, a built-in clock function, etc. can be performed.

  The user identification program 32 is a program for causing the CPU 10 to realize a function of identifying a user from the physical feature amount detected by the physical feature detection unit 18. In the present embodiment, a fingerprint pattern of a finger that the user presses the shutter is detected and identified by comparing with a pattern registered in advance. The identification method can be appropriately realized using a conventional identification technique.

The shooting tendency storage control program 33 is a program for causing the CPU 10 to realize a function of storing information related to the shooting tendency of the user in the storage medium 72 every time shooting is performed. Specifically, a control value acquisition program 331 is included.
The control value acquisition program 331 has a function of acquiring each control value such as an aperture value, shutter speed, subject distance, and substantial focal length from the photographing unit 12 in the CPU 10 and acquiring a shaking amount as a control value from the shaking amount detection unit 16. This is a program to be realized.

  The shooting tendency display control program 34 calculates information about the user's shooting tendency (control value in this embodiment) cumulatively stored in the storage medium 72 in the CPU 10 and performs statistical processing on each item. And the function of controlling the display of the statistical feature value on the display unit 40 is realized. The statistical feature value referred to here is, for example, an average value, a maximum value, a minimum value, a maximum frequency value, or a frequency value or a ratio for each predetermined band.

The script editing program 35 causes the CPU 10 to realize a function of editing a script and automatically translating it into a machine language. A script is a simple program that can be easily executed by automating the conversion to machine language.
A plurality of types of scripts are stored in advance in the script information 38, and a simple program can be created by the user editing the types and execution order of the scripts. Specifically, it can be realized by a known script language. In this embodiment, the user has a function of setting a name that is an identifier and a priority of execution in a program newly created by the user (hereinafter referred to as “additional program” as appropriate), and the additional program is a retouching program. It can be used in the same manner as the retouch program included in the group 37.

  The retouch control program 36 is a program for causing the CPU 10 to read out and execute a retouch program stored in the retouch program group 37 and realize various image processing functions.

  The retouch program group 37 stores in advance a plurality of retouch programs for causing the CPU 10 to execute various retouch processes in association with the names of the retouch programs and program codes. For example, as shown in FIG. 3C, a contrast correction program for sharpening the brightness, a whiteout correction program for correcting so-called “whiteout” in which the highlight portion is white, and daylight such as morning and evening A color temperature correction program for correcting the color balance of an image photographed under different color temperatures, and a defocus correction program for correcting the blur of the main subject by edge enhancement processing are stored. Needless to say, the programs stored in the retouch program group 37 may be set as appropriate.

  The priority setting TBL 39 is a condition for setting a priority for each retouching program stored in the retouching program group 37 on the basis of information on shooting tendency for each user (in this embodiment, a statistical feature value of a control value). And a point value added to the priority of the retouch program are stored in association with each other.

  FIG. 4 is a diagram illustrating an example of a data configuration of the priority setting TBL 39 in the present embodiment. As shown in the figure, the priority setting TBL 39 is a feature value condition 39 a, a target program ID 39 b indicating a retouch program to be processed for increasing the priority, and an addition added to increase the priority of the retouch program. The point value 39c is stored in association with each other. In the present embodiment, for each of the conditions 39a, it is determined whether or not the statistical feature value satisfies the condition. If it is determined that the condition is satisfied, an additional point is added to the priority of the photo retouching program indicated by the target program ID 39b. The value 39c is added. Therefore, the total value of the priorities indicates the fitness corresponding to the user's photographing tendency.

  Specifically, for example, when the first stage of the TBL satisfies the condition of “the peak value (unit: sec) of shutter speed frequency distribution is smaller than“ 1/60 seconds ”” (39a-1), It can be determined that the condition tends to cause blurring on the screen. Since an image taken under such shooting conditions often has an unclear outline, it is determined that it is appropriate to execute the outline enhancement program, and “2” points are added to the priority of the program. It is shown that. Further, the same condition further indicates that it is appropriate to execute a defocus correction program in order to make the subject appear more clearly, and “1” points are added to the priority of the program.

  FIG. 5 is a diagram showing an example of the configuration of the storage area of the storage medium 72 in the present embodiment. As shown in FIG. 6A, the storage medium 72 in the present embodiment includes a captured image storage area 721R for storing image data of an image captured by the capturing unit 12, and information regarding the capturing tendency for each user. It has an imaging tendency information storage area 722R for storing, and an additional program storage area 723R.

  Shooting tendency information 722 stored in the shooting tendency information storage area 722R includes, for example, as shown in FIG. 5B, a user identifier 722a, physical feature information 722b of the user, and each control value 722c for each shooting. The statistical feature value 722d for each item of the control value and the priority setting value 722e set in the retouch program are stored in association with each other. The physical feature information 722b is information serving as a reference for identifying the user in comparison with the detection result of the physical feature detection unit 18. For example, in this embodiment, fingerprint pattern information is stored.

  The statistical feature value 722d appropriately stores an average value, a peak value of a frequency distribution, a frequency ratio, and the like corresponding to each control value item. For example, for the “shutter speed” item 722c-2, an average value and a peak value are stored. In the “flash” item 722c-5, the ratio of using the flash and the average value of the subject distance when used are stored. For the item “722c-6” of “shake amount”, a flag indicating “shake shake” is stored when the shake amount detected by the shake amount detection unit 16 satisfies a predetermined reference condition. Alternatively, a specific swing direction, amplitude / period at that time, and the like may be stored. It should be noted that the control value item is not limited to the example shown in FIG.

  The priority setting value 722e stores the total value of points set with reference to the priority setting TBL39 in association with each retouch program. In other words, the priority point stored here indicates a degree suitable for correcting the problem of the image that the corresponding photo retouching program is predicted to arise from the user's shooting style.

  The additional program storage area 723R stores the name (identifier) of the additional program newly created by the user by editing the script, the specified priority, and the execution code executable by the CPU 10 in association with each other. For example, when the user desires to execute the program before other retouching programs, the specified priority may be set higher than the priority point total that can be set in the retouching program.

[Description of process flow]
Next, the flow of processing will be described.
FIG. 6 is a flowchart for explaining the flow of processing in the present embodiment. The processing described here is realized by the CPU 10 reading and executing the system program 31, the user identification program 32, the shooting tendency storage control program 33, the shooting tendency display control program 34, the script editing program 35, and the retouch control program 36. Is done.

  First, when the user presses the power switch 1018 and the power is turned on, the activation process is executed, and the CPU 10 reads the system program 31 from the ROM 20 and activates the digital camera 1000 (step S2).

  Next, the CPU 10 reads the user identification program 32 and executes a user identification process (step S4). Specifically, when the user touches the shutter button 1010, the fingerprint detection sensor 1022 detects the user's fingerprint pattern. The CPU 10 identifies the user by comparing the detected fingerprint pattern with the physical feature information 722b of the shooting tendency information 722. As a result of the identification, a copy of the user identifier 722a is stored in the user identifier storage area 21R of the RAM 20 so that the user who is currently using the digital camera 1000 can always be confirmed. The shooting tendency information 722 to be processed in the following processing corresponds to the user identifier stored in the user identifier storage area 21R.

  When the user identification processing is completed, the digital camera can be used, and various function settings and functions can be called by operating predetermined input keys 1016.

  As one of the function setting calls, when the user performs a function setting operation related to the automatic execution of image processing (step S6; YES), the CPU 10 switches a flag indicating whether or not to execute the automatic image processing. And stored in the RAM 20 (step S8). The automatic execution of image processing referred to here is a setting as to whether or not to automatically execute retouch processing on a captured image in accordance with the user's shooting tendency.

  As one of the function setting calls, when the user performs an operation for creating an additional program (step S10; YES), the CPU 10 reads the script editing program 35 and executes an additional program creation process (step S12). .

  FIG. 7 is a flowchart for explaining the flow of additional program creation processing in the present embodiment. First, the CPU 10 executes script list editing (step S70). Specifically, in the same manner as in the conventional script language list editing, for example, a script option is displayed in a menu and the user selects it to create a list in which a plurality of scripts are arranged in the execution order.

  Next, the edited / created script list is automatically translated into a machine language, and an execution code of a new additional program is generated (step S72). Then, according to the operation by the user, the identifier of the additional program and the specified priority are input (step S74), and the input identifier, the specified priority and the execution code are associated with each other and stored in the additional program storage area 723R. (Step S76), the additional program creation process is terminated.

  In FIG. 6, when the shutter button 1010 is pressed by the user and the shutter is released (step S14; YES), the photographing process is executed in the same manner as a conventional digital camera to photograph an image (step S40). That is, the potential obtained for each pixel is read from the image sensing unit 121 and one piece of image data is generated.

  Next, the captured image data is stored in the memory card 1012 (step S42). The CPU 10 reads and executes the control value acquisition program 331, acquires each control value at the time of shooting from the shooting unit 12 and the shake amount detection unit 16, and stores it in the shooting tendency information 722 (step S44). Then, a preview of the photographed image is displayed on the display 1008 for a predetermined time (for example, 2 seconds) (step S46).

  While the preview is displayed on the display 1008, the CPU 10 recalculates and updates the statistical feature value 722d of each item including the control value newly stored in step S44 (step S48).

  Then, referring to the priority setting TBL39 (step S50), the priority is set for each retouching program based on the updated statistical feature value 722d (step S52). Specifically, for each condition 39a of the priority setting TBL39, it is determined whether or not the statistical feature value 722d of the shooting tendency information 722 satisfies the condition. When it is determined that the condition is satisfied, the additional point value 39c is added to the priority of the priority setting value 722e corresponding to the retouch program of the target program ID 39b. That is, steps S44 to S52 correspond to processing for storing information related to the user's photographing tendency in the present embodiment.

  If the user performs a shooting tendency display operation after shooting (step S16; YES), the CPU 10 displays the statistical feature value 722d of the control value on the display 1008 (step S18).

  When the flag indicating “Yes / No” for automatic execution of image processing stored in the RAM 20 is set to “Yes” for automatic execution (step S20; YES), the CPU 10 prioritizes the shooting tendency information 722. Referring to the degree setting value 722e, a retouch program and an additional program whose priority exceeds a predetermined reference value, or a predetermined number of retouch programs and additional programs from the higher priority are selected (step S22), and the selected program is read. And retouching the most recently captured image (step S24), and rewriting the image data of the image stored in the storage medium 72 with the image data after the image processing (step S36).

  When the image processing setting flag is set to “not execute” automatically (step S20; NO), and the user performs a call operation of a predetermined image processing function (step S26; YES), the CPU 10 tends to shoot. The priority setting value 722e of the information 722 is referred to, and the identifier (name) of the retouching program and the additional program is displayed on the display 1008 in a menu in order of priority (step S28).

  When the user selects a program from the menu display (step S30), the CPU 10 reads and executes the selected program, performs image processing on the most recently captured image, and displays the result on the display 1008 (step S32). . When the user views the image after image processing and determines that the result is good and performs a save operation (step S34; YES), the CPU 10 uses the image data of the image stored in the storage medium 72 as the image after image processing. Data is rewritten (step S36).

[Description of display screen example]
8 and 9 are diagrams showing examples of screens in the present embodiment.
FIG. 8A corresponds to step S46 and shows a screen on which a photographed image 3a is displayed as a preview. In addition, on the same screen, a file name 3b assigned to the image data and a menu 3c capable of calling various functions corresponding to the input key 1016 are displayed. For example, when the input key 1016 corresponding to the “setting” menu is pressed, various setting menus such as image data file format selection and white balance selection are called up in the same manner as in a conventional digital camera. The function can be set.

When the input key 1016 corresponding to the “shooting trend” menu is pressed (step S16; corresponding to YES), the CPU 10 sets the control value stored in the shooting tendency information 722 as shown in FIG. 8B, for example. The statistical feature value 722d of each item is displayed. In the case of the figure, each control value item is selectably displayed on the menu display M1, and when an item is selected with a direction key or the like, the statistical feature value 722d of the selected item is displayed on the feature value display unit M2. . The user can grasp his / her own photographing tendency by viewing this display.
The feature value display unit M2 is not limited to displaying specific numerical values of the statistical feature value 722d, and the control value graph M3 stored in the shooting tendency information 722 and the tendency are expressed in words. You may display text. The “text expressing the tendency in words” is, for example, “if you tend to use telephoto well” when the first peak of the focal length is 125 mm. Such text is stored in the ROM 30 in the form of text TBL in advance and referred to as appropriate.

  When the input key 1016 corresponding to the “retouch” menu is pressed, the CPU 10 displays a menu display M5 in which a function related to retouch can be selected, for example, as shown in FIG. For example, if “manual retouch” is selected (corresponding to step S26; YES), for example, as shown in FIG. 9A, the CPU 10 can select the name (identifier) of the retouch program and the additional program. The menu display M6 is displayed (corresponding to step S28).

  In the menu display M6, the names of the retouching program and the additional program are displayed in the order of priority based on the shooting tendency of the user. Therefore, even when there are a plurality of types of retouching programs, a program that is considered highly necessary is displayed. Easy to select. In particular, it is convenient for a novice user who is unfamiliar with retouching, because appropriate programs are arranged in the order derived from his / her own shooting tendency, even if the name alone does not know what effect can be obtained. Furthermore, only the names of programs whose priorities exceed a predetermined reference value are displayed, or the names of programs exceeding a predetermined reference value are displayed in a different display form, so that the program names are displayed in priority order. Alternatively, the user may easily select a necessary and sufficient program.

  When the input key 1016 corresponding to the “execute” menu is pressed after selecting a program on the screen of FIG. 9A (corresponding to step S30), the CPU 10 reads and executes the selected retouch program, For example, as shown in FIG. 9B, photo retouching may be performed on the image to display the retouched image 3d (corresponding to step S32). When the input key 1016 corresponding to the “Save” menu is pressed (corresponding to YES in Step S34), the retouched image is saved. Therefore, the user can check his / her own shooting tendency and can easily execute photo retouching suitable for his / her own shooting tendency.

  For example, when the automatic execution of image processing is set to “Yes” (corresponding to YES in step S20), the retouch program is automatically executed after the preview screen shown in FIG. ) Is displayed. As shown in the figure, the menu 3c provides “OK” and “Cancel” for the user to select whether or not to perform image processing. When “OK” is selected, the automatically executed retouching is saved, When “Cancel” is selected, automatic execution of image processing may be canceled.

  Through the above processing, the user can confirm information related to his / her own shooting tendency and can easily perform retouching according to the shooting tendency.

[Second Embodiment]
Next, as a second embodiment of the present invention, an example in which information relating to a user's photographing tendency is stored based on the result of image analysis of color information of a photographed image, and retouching according to the photographing tendency is easily realized. Show. The present embodiment can be basically realized by the same configuration as that of the first embodiment, and the same components are given the same reference numerals as those of the first embodiment, and description thereof will be omitted as appropriate.

  FIG. 10 is a diagram illustrating an example of information stored in the ROM 30 in the present embodiment. As shown in the figure, the ROM 30 in the present embodiment includes an image analysis program 332 in the photographing tendency storage control program 33.

  The image analysis program 332 is a program for causing the CPU 10 to realize a function of analyzing the color information of the captured image. In the present embodiment, a function for calculating the luminance distribution for each primary color and the luminance distribution for the total luminance, and a function for calculating the area ratio of pixels of a specific primary color system by comparing the luminance distributions for each primary color are realized.

FIG. 11 is a diagram illustrating an example of a data configuration of the shooting tendency information 722-2 in the present embodiment. As shown in the figure, in the present embodiment, the luminance distribution of each primary color component of R (red), G (green), and B (blue) and the luminance distribution that combines the primary color components for each captured image. The total luminance distribution is stored in the photographing tendency information 722-2 as the analysis result 722f, and the statistical feature value 722g corresponding to each item of the analysis result is stored.
Specific examples of the statistical feature value 722g include, for example, an average area ratio occupied by pixels of the primary color (that is, pixels displayed as red if red), and a peak value of the luminance frequency of the primary color. There is. Of course, it may be set as appropriate. The primary color components here are not limited to RGB, but may include C (cyan), M (magenta), and Y (yellow) as components, and are set according to the specifications of the color filter to be used. Is appropriate.

FIG. 12 is a diagram illustrating an example of a data configuration of the priority setting TBL 39-2 in the present embodiment. As shown in the figure, in the present embodiment, the feature value condition 39a includes a condition related to image color information.
Specifically, for example, when the condition 39a is “the average area ratio of the specific primary color system exceeds 40%” (39a-3), the user tends to photograph the subject of the color of the specific primary color system. It is determined that it is appropriate to execute the specific primary color information bit appropriate distribution program. For example, when the color information of the specific color of the image data has only an information width of 12 bits with respect to an output width of 30 bits of an image sensor such as a CCD, the program stores the color information of the primary color system. The information bits are optimized so that the intermediate component is more importantly included in the 12 bits.
Further, in the case of the condition “only the histogram of the specific primary color system has a peak at high brightness” (39a-4), the user tends to take a photograph of a subject with a bright color of the specific primary color system. Judge that it is appropriate to run a saturation enhancement program. For example, when the red luminance peak is higher in luminance than the other primary colors, the program executes a process of relatively increasing the saturation of red.
In addition, on the condition that the total luminance distribution is shifted to the high luminance side, a program that adjusts the histogram and executes the process of averaging the lightness distribution of the image may be associated.

  FIG. 13 is a flowchart for explaining the flow of processing in the present embodiment. As shown in the figure, the processing flow in the present embodiment is basically the same as in the first embodiment. A characteristic step in the present embodiment is a series of processes when the shutter is released (step S14; applicable after YES branch).

While displaying the preview of the image captured in step S46, the CPU 10 reads and executes the image analysis program 332, executes image processing of the image, and analyzes the analysis result of the imaging tendency information 722-2. The result is stored in the result 722f (step S60).
Then, the CPU 10 recalculates and updates the statistical feature values 722d and 722g of each item including the control value newly stored in step S44 and the analysis result newly stored in step S60 (step S48). ).

  FIG. 14 is a diagram illustrating an example of a screen in the present embodiment. FIG. 6A corresponds to step S46, and shows a screen on which a photographed image 3a is displayed as a preview. In addition, the file name 3b assigned to the image data and a menu 3c that can be called in response to the input key 1016 are displayed on the screen.

When the input key 1016 corresponding to the “shooting tendency” menu is pressed (step S16; corresponding to YES), the CPU 10 displays a menu display M7, for example, as shown in FIG. In addition, as a result of the image analysis, items relating to each primary color component and total luminance (“total luminance”, “red”, “green”, “blue”) are displayed in a selectable manner.
For example, when “green” is selected, the statistical feature value 722g of the selected item is displayed on the feature value display unit M2. The user can grasp the tendency of the color of the subject that he / she likes to shoot by looking at this display. The feature value display unit M2 is not limited to displaying specific numerical values of the statistical feature value 722g, but may be a histogram of the primary color system M8 or a text expressing the tendency in words. The “text expressing the tendency in words” is, for example, “If you have a peak with high brightness compared to other primary color components, you tend to prefer bright red subjects”. Such text is prepared in advance so as to correspond to the value of the feature value, for example, stored in the ROM 30 in the form of text TBL, and is referred to as appropriate.

  In this embodiment, as shown in FIG. 6C, the retouch program and the additional program are displayed on the menu display M6 so that a retouch program for correcting the saturation and lightness of the color of the captured image can be selected. (Corresponding to step S28).

  Therefore, the user can confirm the tendency of the subject that he / she likes, and can easily perform photo retouching suitable for his / her photographing tendency. For example, users who prefer to take pictures of the blue sky and the blue sea can easily adjust the color to suit their preferences, such as processing to increase the saturation of blue and processing to make the intermediate colors of blue more rich. realizable.

As shown in the figure, the digital camera 1002 basically has the same components as the digital camera 1000 of the first embodiment. In particular, it includes a position information acquisition unit 17 and a shooting direction detection unit 19.

  The position information acquisition unit 17 is realized by, for example, a receiver that receives a signal from a GPS satellite or a communication device that communicates with a mobile phone or a PHS base station, and outputs the received signal to the CPU 10. In FIG. 15, the position information sensor 1034 corresponds to this. The CPU 10 calculates latitude and longitude as geographical position information of the digital camera 1002 from the signal from the GPS satellite output from the position information acquisition unit 17 and the signal from the base station.

  The shooting direction detection unit 19 is realized by, for example, an acceleration sensor, a tilt sensor, and a geomagnetic sensor, acquires information on the horizontal direction component and the vertical direction component of the shooting direction, and outputs the information to the CPU 10. In FIG. 15, the orientation sensor 1032 and the orientation sensor 1036 for detecting the orientation from the geomagnetism correspond to this. The CPU 10 calculates the direction and the elevation angle in the shooting direction Vp from the change in acceleration based on the azimuth output from the shooting direction detection unit 19.

  The communication unit 50 in this embodiment corresponds to the wireless communication device 1030 in FIG.

  FIG. 17 is a diagram illustrating an example of information stored in the ROM 30 according to the present embodiment. As shown in the figure, the ROM 30 in this embodiment includes a shooting tendency storage control program 33, a shooting direction calculation program 333, a geographical position information acquisition program 334, and a subject information acquisition program 335. Moreover, priority setting TBL39-3 and camera ID39-4 are memorize | stored.

The shooting direction calculation program 333 causes the CPU 10 to realize a function of calculating the azimuth and the elevation angle indicating the direction of the shooting lens of the digital camera 1002 from the output signal from the shooting direction detection unit 19.
The geographical position information acquisition program 334 causes the CPU 10 to acquire position information from a GPS satellite, a base station of a mobile phone, or the like by the position information acquisition unit 17 and calculate a latitude and longitude.
The subject information acquisition program 335 sends the camera ID 39-4, the angle of view, the shooting direction, and the subject distance in association with each other by the communication unit 50, and sends the subject returned from the landmark building 64 or temple 96. Realize the function to receive information.

FIG. 18 is a diagram illustrating an example of a data configuration of the shooting tendency information 722-3 in the present embodiment. As shown in the figure, in this embodiment, the subject information acquisition program 335 is executed to store the acquired subject information 722h and the statistical feature value 722j for each item of the subject information 722h.
The subject information 722h includes, for example, a subject name, a subject type, a subject background, and weather. The “type of subject” is, for example, a linear modern architecture mainly made of concrete or the like, or a historical building using a lot of wood or the like. “Subject background” is, for example, other modern architecture, mountains, plants, sky, sea, or the like. The statistical feature value 722j stores the frequency (ratio) of each of these elements.

FIG. 19 is a diagram illustrating an example of priority setting TBL39-3 in the present embodiment. As shown in the figure, in the present embodiment, the condition 39a for the feature value includes a condition related to subject information. Specifically, for example, when the condition 39a is “contemporary architecture exceeds 40% as a subject to be photographed” (39a-5), the user tends to photograph subjects with many geometric straight lines, and the contour line It is determined that it is appropriate to execute the enhancement program and the contrast enhancement program. For example, the contour line emphasis program emphasizes a linear portion of a subject such as a building or a bridge, and makes the subject's features more prominent.
Also, when the condition 39a is “historical building exceeds 40% as a subject to be photographed” (39a-6), there is a tendency that the user prefers to photograph a subject with a tasteful color tone that has passed through the years, and an intermediate information bit. It is determined that it is appropriate to execute the intermediate color gamut information bit appropriate distribution program that distributes more of the image. The program is, for example, a program for making the characteristics of the subject more prominent by correcting so that the color passing through the years is expressed with rich gradation.
In addition, on the condition that the total luminance distribution is shifted to the high luminance side, the histogram may be adjusted, and a program for executing processing for averaging the lightness distribution of the image may be associated.

  16, the subject information servers 94a and 96a include a CPU 910, a RAM 920, a ROM 930, a communication unit 950, and a storage medium reading unit 970 that can read and write data from the storage medium 972, and are connected by a bus 980. Servers of the same configuration. In particular, the RAM 920 has a subject information storage area 922R, and stores subject information of the building 94 and the temple 96.

The CPU 910 reads and executes a program stored in the ROM 930 or the storage medium 972, and controls the subject information servers 94a and 96a in an integrated manner using the RAM 920 as a temporary storage means for the program and data.
The communication unit 950 corresponds to the wireless communication devices 94b and 96b in FIG.

[Description of process flow]
FIG. 20 is a flowchart for explaining the flow of processing in the digital camera 1002 according to this embodiment.
The flow of processing in the digital camera 1002 in this embodiment is basically the same as the processing in the digital camera 1000 of the first embodiment. A characteristic step is an image tendency storage process in a series of processes when the shutter is released (step S64).

  FIG. 21 is a flowchart for explaining the flow of the image tendency storage process in the present embodiment. The flow on the left of FIG. The flow on the right side of the figure shows processing in the subject information servers 94a and 96a, and wireless communication via the communication line 2 is indicated by broken line arrows.

  As shown in the figure, first, in the digital camera 1002, the CPU 10 reads out and executes the control value acquisition program 331 in the same manner as in the first embodiment, and receives the control values from the imaging unit 12 and the shake amount detection unit 16, respectively. It is acquired and stored in the shooting tendency information 722-3 (step S42).

  Next, the shooting direction calculation program 333 is read and executed, and the shooting direction is calculated based on the output signal from the shooting direction detection unit 19 (step S82). Specifically, based on the azimuth output from the azimuth sensor 1036, the shooting direction (azimuth and elevation angle) is calculated from the tilt amount and acceleration change output from the attitude sensor 1032. Then, the geographical position information acquisition program 334 is read and executed to calculate the latitude and longitude of the digital camera 1002 from the output signal from the position information acquisition unit 17 (step S84).

  When the shooting direction and the geographical position information are obtained, the CPU 10 associates the camera ID, the actual focal length, the shooting direction, the geographical position information, the subject distance, and the aperture value with each other to communicate with each other. 50 is transmitted by radio (step S86).

  The subject information servers 94a and 96a receive information wirelessly transmitted from the digital camera 1002 (step S100), and the real focal length, shooting direction, geographical position information and subject distance included in the information, and the subject information server 94a. , 96a is compared with information such as the geographical position information and size of the landmark, and it is determined whether or not the landmark is the main subject (step S102). Specifically, the landmark exists within the range of the angle of view obtained from the shooting direction and the actual focal length from the geographical position information of the digital camera 1002, and the actual focal length, the aperture value, and the subject It is determined from the distance whether or not the landmark is in focus.

  If it is determined that the landmark is the subject (step S104; YES), background information is selected (step S106). Specifically, the background of the landmark included in the range of the angle of view obtained from the shooting direction and the actual focal length is selected starting from the location indicated by the geographical position information of the digital camera 1002.

Then, the camera ID included in the information received from the digital camera 1002 and the subject information (including information related to the background selected in step S106) are associated with each other and transmitted wirelessly from the wireless communication devices 94b and 96b. (Step S108).
In the case of FIG. 15, since the digital camera 1002 has the building 94 as a subject, the subject information server 94a determines that the building 94 is a subject and transmits subject information of the building 94. On the other hand, the subject information server 96a of the temple 96 determines that the temple 96 is not a subject, and does not transmit subject information of the temple 96.

  When the digital camera 1002 receives the subject information from the subject information servers 94a and 96a within a predetermined time after transmitting the shooting information (step S88; YES), the camera ID associated with the subject information is itself. It is determined whether or not the ID matches. If they match (step S90; YES), it is determined that the subject information is sent to the subject, and the received subject information is stored in the subject information 722h of the shooting tendency information 722-3 (step S92). The image tendency storage process in the embodiment is terminated.

  In FIG. 20, if the image trend storage process is completed, the statistical feature value is calculated while the captured image is displayed as a preview, as in the first embodiment, and the calculated statistical feature value is displayed. The priority is set for the retouching program based on (Steps S46 to S52). Hereinafter, the processing flow is the same as that of the first embodiment, and a description thereof will be omitted.

  FIG. 22 is a diagram illustrating an example of a screen in the present embodiment. FIG. 11A corresponds to step S46 in FIG. 20, and shows a screen on which a photographed image 3a is displayed as a preview. In addition, the file name 3b assigned to the image data and a menu 3c that can be called in response to the input key 1016 are displayed on the screen.

  When the input key 1016 corresponding to the “shooting tendency” menu is pressed (corresponding to step S26 in FIG. 20; YES), the CPU 10 displays a menu display M9, for example, as shown in FIG. Items (“subject type” items) are displayed so as to be selectable. For example, when “subject type” is selected, a statistical feature value 722j regarding the subject type is displayed on the feature value display unit M2. The user can grasp the type of subject that he / she likes to shoot by looking at this display.

  In this embodiment, as shown in FIG. 5C, the retouch program and the additional program are displayed on the menu display M10 so that a retouch program for correcting the feature of the photographed subject can be selected more clearly. (Corresponding to step S28 in FIG. 20).

  Therefore, the user can confirm what kind of subject he / she likes, and can easily execute an appropriate photo retouching to draw the characteristics of the subject to be preferred. For example, in the case of a user who captures a large amount of urban scenery, the proportion of contemporary architecture as a subject increases, and a sharper image with edges and contrast enhanced can be obtained.

  As described above, the embodiments to which the present invention is applied have been described. However, the application of the present invention is not limited to these embodiments, and components may be added, changed, or omitted as appropriate without departing from the spirit of the invention. I do not care.

  For example, the identification of the user is performed by the fingerprint pattern, but the identification may be performed by the iris pattern or the voice pattern of the user's pupil, for example. For example, in the former case, an image sensor for photographing the user's pupil is provided in the viewfinder 1002, and a glow pattern is acquired. Then, the user is identified by comparing with the glow pattern registered in the physical feature information 722b of the photographing tendency 722. The glow pattern comparison algorithm can be realized by appropriately applying known techniques. In the latter case, the digital cameras 1000 and 1002 are provided with a sound collecting device such as a microphone to collect sound such as a user's name. Then, the user is identified by comparing with the pronunciation pattern of the user's name registered in the physical feature information 722b of the photographing tendency 722. The voice pattern comparison algorithm can be realized by appropriately applying a known technique.
