Abstract
An image pickup apparatus capable of capturing a still image while a high sharpness is being maintained and a reduction in image quality due to the existence of a focus detecting pixel is being suppressed. An image pickup device includes an image pickup pixel group and a focus detecting pixel group. A calculation unit calculates a singular value in the signal values of pixels existing around the focus detecting pixel group. An adjustment unit adjusts a gain of signal values in the focus detecting pixel group. A correction unit corrects an image data corresponding to the position of the focus detecting pixel group based on the signal values in the image pickup pixel group. A determination unit determines the amount of adjusting the gain of signal values in the focus detecting pixel group and the amount of correction based on the results calculated by the calculation unit.
