1. A control apparatus comprising:
at least one processor; and
a memory coupled to the at least one processor,
wherein the memory has instructions that, when executed by the processor, perform operations as:
an acquiring unit configured to acquire a position of an optical system based on an image signal; and
a predicting unit configured to predict an in-focus position of the optical system based on the position acquired by the acquiring unit,
wherein the acquiring unit acquires the position of the optical system by performing interpolation processing in a range equal to or wider than an interval between first accumulation center time for a first frame in the image signal and second accumulation center time for a second frame in the image signal.
