Abstract
The present disclosure relates to an arithmetic device that reduces a scale of an arithmetic processing unit which performs an arithmetic process between frames in a sensor. A frame memory stores pixel data of a frame that transitions in time sequence. An inter-frame arithmetic processing unit implements a predetermined arithmetic by column parallel in a row unit on the pixel data of a current frame and the pixel data of a past frame stored in the frame memory and updates the pixel data of the past frame stored in the frame memory on the basis of a result of the predetermined arithmetic.
