IMAGE PICKUP ELEMENT, RADIATION DETECTOR AND METHOD FOR CONTROLLING IMAGE PICKUP ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a technique achieving extremely short-time exposure in an image pickup element.SOLUTION: A photoelectric conversion element converts light into electric charges to be accumulated. A floating diffusion layer generates voltage corresponding to an amount of the electric charges transferred from the photoelectric conversion element. A floating diffusion layer reset transistor initializes the generated voltage. A conversion section performs conversion processing for converting the voltage into a digital signal. A photoelectric conversion element reset transistor initializes an amount of the electric charges having been accumulated in the photoelectric conversion element at a predetermined timing after the voltage has been initialized. A transfer transistor performs transfer from the photoelectric conversion element to the floating diffusion layer when an exposure time shorter than a time required for the conversion processing has elapsed from the predetermined timing.
