An image pickup apparatus has a solid-state image pickup device which outputs a charge signal according to a timing signal, a sampling unit which samples the charge signal in response to the timing signal, an A/D converting unit which converts a sample signal to a digital signal in response to the timing signal, and a timing unit which, in response to the number of first clocks in a horizontal period of the timing signal when a picture signal is outputted at a first frame rate (60 fps), generates a timing signal having the number of clocks in the horizontal period higher than the number of the first clocks, and supplies a timing signal based on the generated timing signal, the sampling unit, and the A/D converting unit in case of a second frame rate (50 fps) lower than first frame rate.
