ABSTRACT:
An image pickup device includes a decision circuit for comparing a signal amount stored in each pixel of a solid-state image pickup element with a predetermined signal amount which is set in advance, thereby deciding which of the two signal amounts is larger, a time measuring circuit for measuring a time required for the signal amount stored in each pixel to reach the predetermined signal amount, and an operating circuit for operating the stored signal of the pixel whose stored signal amount is found to be larger than the predetermined signal amount by the decision circuit, on the basis of the time information obtained from the time measuring circuit.
