PPROBLEM TO BE SOLVED: To eliminate a noise signal component to be superimposed on image data caused by interference of various clock signals by miniaturizing an imaging apparatus. PSOLUTION: The periodical pattern of a beat noise to be superimposed on image data is predicted by using an imaging clock frequency and the number of clocks of a horizontal synchronizing signal from a frequency having the possibility of being interfered with from a driving frequency of a circuit. The periods of repeating an interference noise signal are averaged more than once from the result of the prediction for each of decided lines, and a random noise component is canceled to detect and cancel an interference noise signal component.
