A first control unit, which controls the timing when a first image pickup unit starts exposure, obtains a second difference by subtracting a first difference from an exposure-output time of the first image pickup unit, and outputs a first control signal for delaying the timing when the first image pickup unit starts exposure, by the second difference. The exposure-output time is a time lag between when the image pickup unit starts exposure and when output of an image signal obtained by the exposure is started. The first difference is a difference between a timing at which the first image pickup unit started outputting a predetermined image signal and a timing at which a second image pickup unit started an exposure for obtaining an image signal that the second image pickup unit outputted immediately after the first image pickup unit started outputting the predetermined image signal. |
