Image capturing apparatus and image processing method

摘要

An image capturing apparatus includes an image capturing unit and an image processing unit. The image capturing unit captures a subject by an image sensor including focus detection pixels. The image processing unit includes a correction range determination unit configured to determine a range of a correction coefficient based on an optical condition of a photographing optical system, and a correction coefficient calculation unit configured to calculate the correction coefficient based on pixel data of a pixel positioned near the focus detection pixel, and a pixel correction unit configured to correct the pixel data of the focus detection pixel based on the correction coefficient and the range.

1. An image capturing apparatus comprising:
an image capturing unit configured to capture a subject by an image sensor in which focus detection pixels for performing focus detection are arranged at positions of some image capturing pixels, and output image capturing data; and an image processing unit configured to correct, by a correction coefficient, pixel data output from the focus detection pixels, out of the image capturing data, the image processing unit including: a correction range determination unit configured to determine, as a correction range, a range of the correction coefficient based on an optical condition of a photographing optical system configured to form an image on the image sensor; a correction coefficient calculation unit configured to calculate the correction coefficient based on pixel data of a pixel positioned near the focus detection pixel; and a pixel correction unit configured to correct the pixel data of the focus detection pixel based on the correction coefficient and the correction range.
