发明名称 IMAGE CAPTURING APPARATUS AND CONTROL METHOD THEREOF
摘要 <p>The image capturing apparatus (10) includes an image sensor 16 photoelectrically converting an object image formed by an image taking optical system (62), first and second photoelectric conversion elements provided in the image sensor or a focus detection element and photoelectrically converting paired focus detecting images formed by light fluxes passing through pupil areas of the image taking optical system, a filter processor (20) performing an image signal restoration process using a filter on first and second image signals obtained from the first and second photoelectric conversion elements, and a focus detector (20, 40) detecting a focus state based on a phase difference between the first and second image signals after the image signal restoration process. The filter processor calculates a contrast direction in which the object image has contrast, by using an output from the image sensor, and changes the filter depending on the contrast direction.</p>
