The assist menu function includes display of an auxiliary frame for composition confirmation on the liquid crystal monitor and shooting according to shooting conditions based on the auxiliary frame. FIG. 2 shows a display example of the auxiliary frame. The auxiliary frame A in the shape of a person in FIG. 2 is displayed superimposed on a through image for composition confirmation described later. Note that shooting conditions related to the scene shooting function and the assist menu function are recorded in advance in a memory (not shown) of the control unit 13.

  The operation at the time of photographing of the electronic camera 1 having the above-described configuration will be described with reference to the flowcharts shown in FIGS. Note that a series of operations according to the flowcharts of FIGS. 3 and 4 is started when an instruction to perform photographing is given through the operation unit 16. Various selection operations related to the setting of the focus detection target area, the shooting scene function, and the assist menu function are performed in advance before the series of operations shown in the flowcharts of FIGS. 3 and 4 is started. And

  When execution of shooting is instructed via the operation unit 16, the control unit 13 detects this and captures a through image via the imaging unit 10 (step S1). The through image is an image obtained by preliminary imaging for composition confirmation. The through image is repeatedly imaged at regular time intervals. The obtained image is temporarily stored in a memory (not shown) in the control unit 13 and is erased when a predetermined time elapses.

  Next, the control part 13 acquires 1st imaging | photography information (step S2). The first shooting information is shooting information that can be acquired before actual shooting (hereinafter referred to as “main shooting”) among shooting information related to shooting. The first shooting information includes the through image obtained in step S1, the position of the set focus detection target area in the scene, and the above-described shooting scene and the type of assist menu.

Next, the control unit 13 performs red-eye detection based on the first shooting information acquired in step S2 (step S3). Here, the red-eye detection is to detect a portion where a red-eye phenomenon is predicted to occur due to the main imaging. In other words, the eye portion of the subject that is predicted to generate the red-eye phenomenon is detected based on the through image.
First, the control unit 13 detects the approximate position of the subject in the through image based on the set position of the focus detection target region, the type of the shooting scene, and the type of the assist menu. For example, when the position of the set focus detection target is in the center, it can be detected that the subject is located near the center of the through image. In addition, for example, when a portrait is selected as a shooting scene and an auxiliary frame from the right (see FIG. 2) is selected as an assist menu, it is detected that the subject is located at the right portion of the through image. it can.

Then, the control unit 13 performs motion detection and color component extraction around the detected position of the subject. Motion detection is performed by comparing two through-images that are subsequently captured and extracting different portions. By further performing such motion detection, the position of the subject in the through image can be detected more accurately.
Furthermore, by extracting the skin color component around the detected subject position, the face portion of the subject in the through image can be detected (hereinafter referred to as “face detection”). In such face detection, combining the positions of the auxiliary frames described above enables more accurate face detection of the subject.

  After performing face detection as described above, the control unit 13 detects the eye part of the subject in the through image. The eye part can be detected statistically if the face part is known. Further, by performing edge detection and the like together, the eye part can be detected more accurately. In this way, the eye part can be accurately detected by including the procedure of detecting the position of the subject in the through image, detecting the face part, and further detecting the eye part. In addition, if such a procedure is used, the eye part can be accurately detected even if the user who is the subject is blinking when the through image is captured.

  Next, the control unit 13 blinks the eye portion detected in step S3 and displays the through image captured in step S1 on the display unit 12 (step S4). And the message which alert | reports to a user that it is estimated that the red-eye phenomenon will generate | occur | produce in the blinking part is displayed. FIG. 5 shows a display example. A blinking point B in FIG. 5 is a portion detected by the red-eye detection described in step S3. Message C is a message for informing the user.

  Next, the control unit 13 determines whether or not the release button is half-pressed (step S5). The controller 13 repeats the operations of Steps S1 to S5 until the release button is half-pressed (Step S5 YES). In addition, about acquisition of the 1st imaging | photography information after the 2nd time (step S2) and red-eye detection (step S3), when it is the same as the last time, you may abbreviate | omit.

  On the other hand, when the release button is half-pressed (YES in step S5), the control unit 13 finishes capturing the through image and acquiring the first shooting information, and performs a shooting preparation operation (step S6). The shooting preparation operation includes focus adjustment based on the result of focus detection, determination of an exposure value according to photometric information by a sensor of the imaging unit 10, and the like. The focus detection result, exposure value, and the like are recorded in a memory (not shown) in the control unit 13 as shooting conditions determined by the shooting preparation operation.

Next, the control unit 13 determines whether or not the release button has been fully pressed (step S7).
The control unit 13 repeats the determination until the release button is fully pressed (YES in step S7), and when the release button is fully pressed, the process proceeds to step S8. When the release button is released in step S7, the control unit 13 returns to step S1 and resumes the capturing of the through image.

Next, the control unit 13 performs main imaging of an object image via the imaging unit 10 (step S8). The control unit 13 performs the main imaging according to the predetermined shooting conditions (for example, shooting conditions associated with the shooting scene) and the shooting conditions determined in the shooting preparation operation in step S6.
Next, the control part 13 acquires 2nd imaging | photography information (step S9). The second shooting information is shooting information that can be acquired after the main shooting among shooting information related to shooting. The second shooting information includes the shooting distance of the subject at the time of shooting, the focal length of the shooting lens, the presence / absence of flash emission, the light emission amount, and the shooting sensitivity.

  Next, the control unit 13 performs image processing via the image processing unit 11 (step S10). The control unit 13 performs white balance adjustment, color reproduction processing, gradation conversion processing, and the like via the image processing unit 11 on the image obtained by the main imaging in step S8. When the scene shooting function and the assist menu function are selected, image processing is performed according to the shooting conditions recorded in association with each shooting scene and assist menu.

  Next, the control unit 13 determines whether or not flash emission has been performed during the main imaging (step S11). The control unit 13 refers to the presence / absence of flash emission from the second shooting information acquired in step S9, and when flash emission is performed (YES in step S11), performs operations from step S12 to step S15 described later. On the other hand, when the flash emission is not performed (NO in step S11), the process proceeds to step S16.

When flash emission is performed during the main imaging (YES in step S11), the control unit 13 performs red-eye detection based on the second shooting information acquired in step S9 (step S12). Here, the red-eye detection is to detect a portion where a red-eye phenomenon occurs in an image obtained by the main imaging.
First, the control unit 13 refers to the result of red-eye detection performed in step S3, and detects the rough position of the subject in the image obtained by the main imaging. Then, the control unit 13 performs face detection around the detected position. When performing face detection, the control unit 13 first estimates the size of the face based on the shooting distance and the focal length. The relationship between the shooting distance and focal length and the size of the subject's face is recorded in advance in a memory (not shown) in the control unit 13. Then, face detection is performed using the estimated face size and skin color component as indices. Then, after detecting the face portion of the subject, the control unit 13 detects the eye portion of the subject as in step S3. As described above, similarly to the red-eye detection described in step S3, the position of the subject in the image obtained by the main imaging is detected, the face part is detected, and the eye part is further detected. , Can accurately detect the eye part.

  Next, the control unit 13 blinks the eye portion detected in step S12, and displays the image obtained by the main imaging in step S8 on the display unit 12 (step S13). Then, a message is displayed asking the user whether to perform red-eye reduction processing on the blinking image. A display example is shown in FIG. A blinking portion B in FIG. 6 is a portion detected by red-eye detection. Message D is a message for asking the user whether to perform red-eye reduction processing. By making such an inquiry, it is possible to allow the user to confirm a portion to be subjected to the red-eye reduction process.

And the control part 13 determines whether execution of the red-eye reduction process was instruct | indicated (step S14). An instruction to execute the red-eye reduction process is given via the operation unit 16. The control unit 13 repeats the operations from step S12 to step S14 until the execution of the red-eye reduction process is instructed (YES in step S14).
When the execution of the red-eye reduction process is instructed, the control unit 13 performs the red-eye reduction process via the image processing unit 11 (step S15).

  The image processing unit 11 performs a process of reducing the saturation of the image of the eye portion detected in step S12 among the images obtained by the main imaging. The degree of red-eye reduction processing may be determined based on the second shooting information. For example, it may be determined based on the shooting distance and the focal length. When the shooting distance and the focal length are short, the reflection of flash emission is large, so it is preferable to increase the degree of red-eye reduction processing. On the other hand, when the shooting distance and the focal length are long, there is little reflection of flash light emission, but rather there is a concern about a decrease in saturation, so it is preferable to reduce the degree of red-eye reduction processing. Further, it may be determined based on the flash emission amount. For example, when the amount of flash emission is large, the reflection of flash emission is large, so the degree of red-eye reduction processing is increased. When the amount of flash emission is small, reflection of flash emission is small, so the degree of red-eye reduction processing is low . Further, it may be determined based on the photographing sensitivity. Further, the degree of red-eye reduction processing may be determined by combining several types of shooting information.

Then, the control unit 13 performs interpolation / compression processing via the image processing unit 11 (step S16). In this way, by performing interpolation / compression after performing the red-eye reduction process, generation of false colors can be suppressed and image quality deterioration can be avoided.
Next, the control unit 13 records the image after the interpolation / compression processing in the recording unit 14 (step S17) and ends the series of operations.

  During the operations of Steps S1 to S4, the user performs various selection operations related to the setting of the focus detection target region, the scene shooting function, and the assist menu function via the operation unit 16. In the case of failure, the control unit 13 detects this and interrupts the operations of step S1 to step S4. And the setting and various selection operation | movement by a user are received, and the operation | movement from step S1 is restarted after that.

In addition, face detection is performed to detect the face portion of the subject in the image captured by the main imaging.
