摘要： Subjects are detected in a captured image and a main subject is selected from the detected subjects. Focusing areas are set up that correspond to the detected subjects and focus detection is performed in the focusing areas that have been set up. When providing in-focus indication representing focus detection results, focus detection results associated with the particular focusing area among the focusing areas that corresponds to the main subject are displayed in a manner different from focus detection results associated with those focusing areas within the depth of field that correspond to subjects other than the main subject.

摘要： A low-frequency region of an output target image is specified. Luminance correction is performed with the target amount decided in advance for a pixel, among pixels included in the target image, which is included in the low-frequency region and has a luminance value equal to or smaller than a predetermined value, and the target image after the correction is output. Then, an effective correction amount is obtained based on the luminance distribution of the target image before the correction and the luminance distribution of the target image after the correction, which has been corrected with the target amount decided in advance. A luminance correction target amount for the next correction target image is decided based on the luminance distribution of the target image and the ratio of the effective correction amount to the target amount decided in advance.
