Abstract:
1. An image-pickup apparatus comprising: an image-pickup element including a plurality of image-pickup pixels configured to photoelectrically convert light from an image-pickup lens and to generate an image of an object, and a plurality of focus detection pixels each configured to receive light which has passed through an area of a part of an exit pupil of the image-pickup lens; a flicker correction value generator configured to generate a flicker correction value for correcting a flicker in an image signal output from the image-pickup pixels; and a flicker corrector configured to correct a flicker in a focus detection signal output from the focus detection pixels based on the flicker correction value, wherein the flicker correction value generator generates a first flicker correction value for each color of the image-pickup pixels including color filters and a second flicker correction value based on the first flicker correction value and a characteristic of a filter included in the focus detection pixels, and wherein the flicker corrector corrects the flicker in the focus detection signal output from the focus detection pixels by using the second flicker correction value.
