The SET key 6 is a key that is pressed when the item displayed by the cursor key 5 is selected and set. The SET key 6 can also be used as a confirmation key.

  Although not shown on the side, a USB (Universal Serial Bus) terminal connection used when connecting to an external device such as a personal computer or a modem and a USB cable is provided, and a fixed lens 12 described later is provided on the front side. (See FIG. 2).

  FIG. 2 is a block configuration diagram showing an outline of the electrical configuration of the digital camera 1. The digital camera 1 includes a CCD (Charge Coupled Device) 17 that constitutes an imaging unit together with a fixed lens 12 and the like, and has an image processing function such as converting an image captured by the CCD 17 into a JPEG (Joint Photographic Experts Group) format. MPU (Micro Processing Unit) 19 is mainly configured.

  On the light receiving surface of the CCD 17, an optical image of the subject is formed through the fixed lens 12, the focus lens 20 and the diaphragm 21. The focus lens 20 is held by a drive mechanism 22 composed of an AF motor or the like, and moves forward and backward on the optical axis when a drive signal output from the AF driver 23 is supplied to the drive mechanism 22 by a control signal from the MPU 19. Perform focusing operation. The diaphragm 21 is driven by a drive signal generated by the diaphragm drive unit 24 based on a control signal from the MPU 19, and adjusts the light quantity of the subject image incident on the CCD 17.

  The MPU 19 is connected with a TG (Timing Generator) 25 that generates a timing signal, and a V driver 26 (vertical driver) drives the CCD 17 based on the timing signal generated by the TG 25. An analog imaging signal corresponding to the luminance of the image is output and sent to the unit circuit 18. The unit circuit 18 is amplified and adjusted by a CDS (Correllated Double Sampling) that holds the imaging signal output from the CCD 17, a gain adjustment amplifier (AGC) that is an analog amplifier that is supplied with the imaging signal from the CDS, and a gain adjustment amplifier. The A / D converter (AD) that converts the captured image signal into image data, and the output signal of the CCD 17 is sampled with the black level matched and sent to the MPU 19 as a digital signal.

  The sent digital signal (imaging signal) is temporarily stored in a DRAM (Dynamic Random Access Memory) 27 and subjected to various image processing by the MPU 19, and finally is a compressed video signal as a flash memory ( FLASH) 28. The stored video signal is read by the MPU 19 as necessary, and is generated into a digital video signal or an analog video signal through processing such as expansion processing, addition of a luminance signal and a color signal.

  Further, the MPU 19 is connected to an MROM (Mask Read Only Memory) 29, a power supply circuit 30, an operation key unit 31 including various switches and keys shown in FIG. 1, and the liquid crystal monitor 4. The MROM 29 is a program ROM in which an operation program or the like of the MPU 19 shown in a flowchart described later is recorded.

  The MROM 29 has 11 types of shutter speed, aperture, EV (Exposure Value) shift, sensitivity, filter, exposure mode, WB (White Balance), color enhancement, sharpness, saturation, and contrast. A plurality of manually settable parameter values are stored for the shooting parameters (see the top view in FIG. 3), and a combination of an aperture value (F) corresponding to an appropriate exposure value (EV) at the time of shooting and a shutter speed. Program AE data and the like constituting a program diagram showing are also stored.

  The MPU 19 controls each part of the digital camera 1 by operating the built-in RAM as a working memory according to the operation program, and according to the program diagram, the charge accumulation time of the CCD 17, the degree of opening of the diaphragm 21, The gain of the gain adjustment amplifier (AGC) of the unit circuit 18 is set. The charge accumulation time set by the MPU 19 is supplied as a shutter pulse to the V driver 26 via the TG 25, and the charge accumulation time, that is, the exposure time is controlled by the V driver 26 driving the CCD 17 according to this. That is, the CCD 17 functions as an electronic shutter. The operation program stored in the MROM 29 includes a program related to autofocus control. Based on the program, the MPU 19 drives the focus lens 20 to perform focusing (autofocus).

  In the photographing mode, the liquid crystal monitor 4 displays sequentially captured images as a through image, and displays a manual photographed image, a model image, advice, and the like described later. In the reproduction mode, video based on the analog video signal generated from the image data recorded in the flash memory 28 is displayed.

  The MROM 29 stores the best shot table 231 shown in FIGS. 3 and 4 together with the program and data.

  The best shot table 231 includes digital cameras set in advance corresponding to 24 types of scenes “person and landscape 1”, “person and landscape 2”, “up”, and “food” that can be selected by the user. This is setting data indicating one shooting condition. This setting data includes parameters corresponding to the parameters (shooting parameters) that can be set in the above-described manual shooting mode, and includes shutter speed, aperture, EV shift, sensitivity, filter, exposure mode, WB (white balance), and color enhancement. , Sharpness, saturation, contrast, and the like, which are composed of parameters indicating the control contents of 11 types of control items that can be controlled by the digital camera 1. In the setting data, “auto” means that the shutter speed, aperture, and WB (white balance) values are determined based on the program AE data and corresponding data stored in advance in the MROM 29.

  In the present embodiment having the above configuration, when the power switch is turned on and the photographing mode is set, the MPU 19 executes the processing shown in the flowchart of FIG. 3 according to the program stored in the MROM 29. That is, the MPU 19 determines whether or not the manual shooting mode is set (step S1). If the manual shooting mode is not set and the auto shooting mode is set, automatic shooting processing is executed (step S16). At this time, if any shooting scene is selected from the best shot table 231 in advance, parameters corresponding to the selected shooting scene are automatically set, and shooting processing is executed.

  When the manual shooting mode is set, the above-described various shooting parameters are set according to the manual operation by the operation of the menu key 2, the cursor key 5, and the SET key 6 (step S2). Then, it is determined whether or not the shutter key 8 is pressed (step S3), and the setting of various shooting parameters according to the manual operation is repeated until the shutter key 8 is pressed. If the shutter key 8 is pressed, shooting processing is executed with the set shooting parameters, and image data obtained thereby is recorded in the flash memory 28 (step S4).

  Further, it is determined whether or not the advice mode is set in advance (step S5). If the advice mode is not set, the process according to this flowchart is ended. Therefore, when the advice mode is not set in the manual shooting mode, the processes of steps S6 to S15 are not executed, and the shooting process is performed with the manually set shooting parameters each time the shutter key 8 is simply pressed. The image data is recorded in the flash memory 28.

  If the advice mode is set, it is determined whether or not there is pre-selection of the shooting scene (step S6). In other words, it is determined in advance whether the user has selected any shooting scene from the best shot table 231. If any shooting scene has not been selected from the best shot table 231 in advance, composition analysis, brightness distribution, face of the shot image (image based on the image data recorded in the flash memory 28 in step S4) From the information such as the detection result and the motion detection result, the shooting scene of the image is automatically determined (step S7).

  In the automatic determination based on the composition analysis in the process of step S7, the composition of the photographed image is analyzed and the composition similar to the composition of the photographed image is taken from the 24 types of photographing scenes stored in the best shot table 231. A scene is searched (first search). In the automatic determination based on the brightness distribution, the brightness distribution of the photographed image is analyzed, and the brightness distribution similar to the brightness distribution of the photographed image is picked up from 24 kinds of photographing scenes stored in the best shot table 231. A scene is searched (second search).

  In the automatic determination based on the face detection result, the number of faces in the photographed image is detected, and the number of faces similar to the number of faces is photographed from the 24 types of photographing scenes stored in the best shot table 231. A scene is searched (third search). In the automatic determination based on the motion detection result, the movement of the subject in the captured image (subject blurring) is detected, and the subject movement similar to the subject movement from the 24 types of shooting scenes stored in the best shot table 231 is detected. (4th search).

  Eventually, any one shooting scene is specified from 24 types of shooting scenes based on such a plurality of searches. That is, when one shooting scene can be specified by any one of the first to fourth searches, only the search is performed, and when one shooting scene cannot be specified by one search, The identification is performed by appropriately combining the first to fourth searches. Further, even if all the first to fourth searches are combined, one shooting scene cannot be specified, and when there are a plurality of specified shooting scenes, a shooting scene with a smaller number is specified from among them.

  That is, in the automatic determination in step S7, one shooting scene is finally determined.

  Next, the shooting parameters of the shooting scene pre-selected or automatically determined from the best shot table 231 are specified. In other words, when there is a pre-selection of the shooting scene (step S6; YES), the shooting parameters of the shooting scene pre-selected from the best shot table 231 are specified. Therefore, for example, when “Flower Up” in shooting scene No. 7 is preselected, shutter speed = auto, aperture = auto, EV shift = 0, sensitivity = standard, filter = × (none), exposure mode = P (open), WB = auto, color enhancement = x (none), sharpness = standard, saturation = <high>, and contrast = standard.

  If there is no pre-selection of the shooting scene (step S6; NO), the shooting parameters of the shooting scene automatically determined from the best shot table 231 in step S7 are specified. Therefore, for example, when “flowing water” of the shooting scene 20 is automatically determined, shutter speed = 1/2 (second), aperture = throttle, EV shift = 0, sensitivity = standard, filter = × (none) In this case, the shooting parameters such as exposure mode = M, WB = auto, color enhancement = × (none), sharpness = <software>, saturation = standard, and contrast = standard are specified.

  Next, it is determined whether or not a correction mode by image processing is set (step S9). When the correction mode by image processing is not set, the image is re-photographed with the photographing parameters specified in step S8, an exemplary image is created, and stored in the DRAM 27 (step S10). As a result, it is possible to obtain a model image that is the same subject and composition as the photographed image but has different photographing parameters and is suitable as a comparison target of the photographed image. That is, since the interval between the shooting at step S4 and the shooting at step S10 is short, it is possible to shoot with substantially the same subject and composition even if camera shake or the like occurs.

  If the correction mode by image processing is set, the image data photographed and recorded in step S4 is read from the flash memory 28 into the DRAM 27 without re-photographing, and this image data is specified in step S8. An exemplary image is created by performing image processing that provides an effect equivalent to the obtained shooting parameter (step S11).

  Here, the image processing that can obtain the same effect as the shooting parameter specified in step S8 means that the image based on the image data shot and recorded in step S4 is shot and recorded with the shooting parameter specified in step S8. If it is performed, this is a process of correcting the image to the closest approximation to the image that would have been obtained.

  That is, as described above, for example, when “flowing water” in the shooting scene 20 is automatically determined, shutter speed = 1/2, aperture = narrowing, EV shift = 0, sensitivity = standard, filter = × (none), Eleven types of shooting parameters are specified: exposure mode = M, WB = auto, color enhancement = × (none), sharpness = <software>, saturation = standard, and contrast = standard.

  On the other hand, a manually shot image is different from the specified shooting parameters in part or all of these 11 types of shooting parameters, that is, at least a part. Accordingly, in step S11, a difference between the shooting parameter at the time of manual shooting and the specified shooting parameter is obtained from these 11 types of shooting parameters, and correction processing is performed on the shot image to fill this difference.

  Specifically, the image blur is corrected according to the difference in shutter speed, the image brightness is corrected according to the difference in aperture, EV shift, sensitivity, and exposure mode, and the WB is corrected according to the difference in WB. Depending on the difference in color enhancement, a specific color is reduced or enhanced, sharpness is corrected according to the sharpness difference, saturation is corrected according to the saturation difference, and contrast is adjusted according to the contrast difference. Correct.

  Therefore, without performing the re-shooting in the step S10, it is possible to obtain a model image suitable as a comparison target of the shot image that has the same subject and composition as the shot image but has different shooting parameters.

  Note that, in exceptional cases, 11 types of shooting parameters of a manually shot image may be exactly the same as the specified shooting parameters. In this case, it is assumed that the photographed image is created as it is as a model image without being corrected in step S11.

  Thereafter, the manually photographed image and the model image created in step S10 or step S11 are displayed on the liquid crystal monitor 4 (step S12). Accordingly, as shown in FIG. 6, for example, a manually photographed image 161 and a model image 162 that are images of “flowing water” and manually photographed are displayed.

  At this time, a character string “Please select an image that you think is better than the above images” is also displayed below the manually-captured image 161 and the model image 162. However, there is no display that suggests which is the manual photographed image 161 and the model image 162. Therefore, the user cannot know which of the images displayed in parallel is the manually captured image 161 and the model image 162.

  Next, it is determined whether the model image 162 has been selected from the images displayed in parallel (step S13). Then, when the model image 162 is selected from the images displayed in parallel, the difference between the shooting parameters specified in step S8 and the manual shooting parameters set in step S2 with respect to the 11 types of shooting parameters. Is detected (step S14). That is, regarding the shutter speed, aperture, EV shift, sensitivity, filter, exposure mode, WB, color enhancement, sharpness, saturation, and contrast, the difference between the shooting parameters at the time of manual shooting and the specified shooting parameters can be obtained. .

  Subsequently, advice display regarding the imaging parameter having the largest difference is performed, and the model image 162 is enlarged and displayed (step S15). If the difference in shutter speed is the largest among the 11 types of parameters as a result of the processing in step S15, for example, as shown in FIG. 7, “the selected image is a model image. In order to take a picture, an advice display 163 consisting of a character string “Please lower the shutter speed.” Is displayed, and the model image 162 is enlarged.

  At this time, the advice display 163 is teaching information relating to a difference between the shooting parameters of the model image 162 selected by the user according to his / her preference and the shooting parameters actually set by the user. Therefore, by setting the shooting parameters according to the advice made up of the teaching information and shooting again, it is possible to retake the image of the user's favorite.

  In addition, it is possible to reflect the user's subjectivity such as evaluation and preference regarding the image on the advice display 163. Therefore, the user can obtain advice for photographing an image reflecting his / her own subjectivity, such as his / her own evaluation and preference, and thus the user can photograph an image reflecting his / her own subjectivity. A learning effect can be obtained.

  In addition, in the present embodiment, since the advice regarding the photographing parameters having a large difference is displayed, the user can learn the parameter setting for photographing his / her favorite image more effectively.

  In addition, since the model image 162 selected by the user is displayed in an enlarged manner, by observing the model image 162 displayed in an enlarged manner while viewing the advice display 163, the understanding level of the suggestion by the advice can be increased.

  In this embodiment, among the plural types (11 types) of shooting parameters, advice on the shooting parameter having the largest difference is displayed. However, the difference between the plurality of types of shooting parameters or all of the shooting parameters is displayed. You may make it display the advice regarding. In this way, the user can learn parameter settings for manually photographing his / her favorite image in detail.

  In the present embodiment, only one model image 162 is displayed. However, a plurality of model images having different shooting parameters may be displayed together with the manually shot image 161. In this way, when the user selects one of the model images, the user's preference can be analyzed in more detail, and the user can set the details of parameter setting for manually shooting his / her favorite image. Can learn.

  In the embodiment, the advice is displayed on the liquid crystal monitor 4. However, a sound emitting function such as a speaker of the digital camera 1 may be provided, and the advice may be performed by voice.

  In step S15, the advice regarding the shooting parameter having the largest difference is displayed. However, priority is given to the shooting parameter, and the shooting parameter having the highest priority is set regardless of the difference. If there is a difference, an advice display regarding the imaging parameter may be performed. Thereby, the user can effectively learn parameter setting for manually photographing his / her favorite image.

  Further, in step S12, the user can select a favorite image without prejudice by not performing a display that suggests which is the manual photographed image 161 and the model image 162. You may make it perform the display which suggests whether it is the manual picked-up image 161 and the model image 162. FIG.

  In step S15, the advice regarding the shooting parameter is displayed. However, it is also possible to simply display the notification indicating whether the user has selected the manual captured image or the model image.

  Furthermore, in the present embodiment, eleven types of shooting parameters are shown, but the shooting parameters are not limited to these, and may be smaller or a single shooting parameter. Conversely, 11 or more types of imaging parameters may be used.
