摘要

PROBLEM TO BE SOLVED: To provide a pixel design and a pixel reading mechanism of an image sensor capable of temporally accurate scanning of the light signal by a lowpass filter.;SOLUTION: A pixel unit 102 includes a multiplexer unit 110 configured to generate at least one first multiplexer signal 118 and a second multiplexer signal 120 different therefrom, and a memory device 112 having at least one first memory unit 114 performing intermediate preservation of the temporally limited integration value of the first multiplexer signal 118, and a second memory unit 116 performing intermediate preservation of the temporally limited integration value of the second multiplexer signal 120. The pixel unit 102 allows for temporally overlapping scanning of the first multiplexer signal 118 and second multiplexer signal 120.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
