An imaging element with rolling shutter drive has pixels (51R, 51L) that each receive one or the other of a pair of light bundles passing through an aperture area for an imaging lens. The pixels (51R) are disposed on a first line arranged in the X direction, and the pixels (51L) are disposed on a second line in the X direction, alternating in the Y direction. A control unit uses a signal group (31) from the pixels (51R) on a line (L1) in FIG. 2 , a signal group (32) from the pixels (51L) on a line (L2), and a signal group (33) from pixels (51R) on a line (L3) to control imaging lens focus on the basis of the phase difference information found from the amount of phase difference between the signal groups (31 and 32) and the amount of phase difference between the signal groups (32 and 33). |
