Abstract
An image sensor includes a plurality of pixels and includes a photodiode configured to operate in both modes of a linear mode for linearly responding to a light incident amount and a photo-voltaic mode for logarithmically responding to the light incident amount, a source follower circuit configured to output a signal voltage according to a signal generated according to an output of the photodiode, an AD converter configured to convert the signal voltage output from the source follower circuit into digital signal data, a frame memory configured to store signal data of one frame, and a conversion function configured to generate, from signal data of a current frame and signal data of a previous frame, an optical signal relating to the light incident amount.
