IMAGE CAPTURING APPARATUS AND CONTROL METHOD THEREFOR |
摘要 |
An image capturing apparatus comprising: an image sensor configured to perform photoelectric conversion on light that enters via an imaging optical system and output an image signal; a focus detection unit configured to detect an in-focus position based on the image signal output from the image sensor; an edge detection unit configured to detect an edge angle and a number of edge of a subject included in an image based on the image signal output from the image sensor; and a correction unit configured to obtain a correction amount for the in-focus position based on the detected edge angle and the number of edge and correct the in-focus position detected by the focus detection unit based on the obtained correction amount. |
