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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electronic camera that adjusts the distance from an optical lens to an imaging surface","description":"An electronic camera includes an image sensor.
