  • Patent number: 10891706
    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.

    Abstract: A system and method for driving a solid-state image pickup device including a pixel array unit including unit pixels. Each unit pixel includes a photoelectric converter, column signal lines and a number of analog-digital converting units. The unit pixels are selectively controlled in units of rows. Analog signals output from the unit pixels in a row selected by the selective control though the column signal lines are converted to digital signals via the analog-digital converting units. The digital signals are added among a number of unit pixels via the analog-digital converting units. The added digital signals from the analog-digital converting units are read. Each unit pixel in the pixel array unit is selectively controlled in units of arbitrary rows, the analog-distal converting units being operable to performing the converting in a (a) normal-frame-rate mode and a (b) high-frame-rate mode in response to control signals.
