Description

Upon receiving the aperture control command from the system controller 129, the lens controller 107 controls the aperture drive mechanism 105 that drives the aperture 102 via the aperture drive control unit 106, and the aperture 102 according to the drive amount received by the aperture control command. To control.

Next, a functional configuration example and operation of the camera DSP 126 will be described using the block diagram of FIG.
The image signal read from the image sensor 112 is amplified by the CDS / AGC circuit 115 as described above, converted into a digital image signal by the A / D converter 116 , and input to the camera DSP 126 via the selector 121.

In step S <b> 502, the system controller 129 determines whether the final focus distance can be determined according to a predetermined condition (for example, priority is given to a close focus distance) from the focus distance detected in each AF frame of interest. If there is only one AF frame of interest, the focus distance detected there is set as the final focus distance. If it is determined that the final focus distance can be determined, the system controller 129 proceeds to S503, and if it is determined that the final focus distance cannot be determined, the process returns to S501 and repeats the processing from the focus scan again.

In this case, in step S507, the system controller 129 estimates the body area from the position of the face area from the face detection result, and the focus detection that overlaps with the body area where the detected focus distance exists within the depth of field. The presence or absence of an area is also detected. If there is a focus detection area that overlaps with the face area and / or the body area in which the detected focus distance exists within the depth of field, the system controller 129 determines in S508 that all of the focus detection areas overlap with the face area. In-focus display is performed on the focus detection area. Note that if there is a focus detection area that overlaps with the body area where the detected focus distance is within the depth of field, the focus detection area is also displayed in focus.
