Abstract
A unit group which is formed by pixel cell rows L1, L2, L1A, and L2A is divided into groups BG1 and BG2. The defocus amount calculating unit calculates a phase difference of the output signal group of the phase difference detecting pixel cells 51R with respect to the output signal group of the phase difference detecting pixel cells 51L for BG1, calculates a phase difference of the output signal group of the phase difference detecting pixel cells 51L with respect to the output signal group of the phase difference detecting pixel cells 51R for BG2, and calculates a defocus amount based on a difference between the two calculated phase differences. The driving unit performs exposure in the order of the pixel cell rows L1 and L2 for BG1 and performs exposure in the order of the pixel cell rows L2A and L1A for BG2.
