Abstract
An image capture apparatus includes a photoelectric conversion unit, an acquisition unit, a first amplification unit, a second amplification unit, and an amplification factor control unit. The photoelectric conversion unit is configured to convert an optical image into an image signal. The acquisition unit is configured to acquire a value related to a correct exposure on a basis of the image signal converted from the optical image by the photoelectric conversion unit. The first amplification unit is configured to amplify the image signal with a first amplification factor. The second amplification unit is configured to amplify the image signal with a second amplification factor. The amplification factor control unit is configured to change the first amplification factor or the second amplification factor based on the value related to the correct exposure.
