An image capturing apparatus obtains the ratio of light quantities of predetermined wavelengths contained in a light beam having passed through a focus detection region where focus detection is to be performed. When the light beam is eclipsed due to the imaging optical system, the image capturing apparatus obtains new correction coefficients obtained by calculating, in accordance with the ratio, eclipse correction coefficients determined in advance for the respective predetermined wavelengths. Then, the image capturing apparatus corrects outputs respectively from the pair of light receiving element arrays using the new correction coefficients, and performs focus detection using the corrected outputs from the pair of light receiving element arrays. |
