Imaging apparatus

An imaging apparatus comprising:

• an AF evaluation value calculation unit configured to calculate an AF evaluation value by integrating, in a single frame period, a focus differential signal value obtained from a focus differential signal generated by obtaining a high frequency component of a luminance signal included in an image signal obtained by photoelectric conversion of a subject image formed by a focus lens through an imaging device and time-differentiating the obtained luminance signal;
• and
• a control unit configured to control a position of the focus lens to maximize the AF evaluation value based on the AF evaluation value inputted from the AF evaluation value calculation unit,
• wherein the AF evaluation value calculation unit includes:
• a high luminance region determination unit configured to extract a feature of each pixel value and determine whether or not the feature is a backlight scene in a dark place;
• and
• a band determination unit configured to determine a band of a contour component of a subject,
• wherein in the band determination unit, when the high luminance region determination unit determines the feature is a backlight scene in a dark place, a focus differential signal value on a low luminance region side in a contour component formed by a boundary between a high luminance region and a low luminance region due to backlighting is excluded from an object for the integration, and the AF evaluation value is calculated using only a focus differential signal value on the high luminance region side in the contour component of the subject to be focused as an object for the integration.
