Abstract
An electronic camera includes an image sensor. The image sensor has an imaging surface irradiated with an optical image of an object scene through a focus lens and repeatedly generates an object scene image. A CPU executes an AF process for adjusting a distance from the focus lens to the imaging surface to a distance corresponding to a focal point, based on the object scene image generated by the image sensor. However, the CPU has a high-luminance excluding function for excluding from a target to be noticed of the AF process a partial image having a luminance exceeding 'TH1' out of the object scene image generated by the image sensor. The CPU determines whether or not a partial image having a luminance exceeding 'TH2' larger than “TH1” exists on the object scene image generated by the image sensor, and turns on the high-luminance excluding function when a determination result is affirmative and turns off the high-luminance excluding function when the determination result is negative.
