Pixel structure of active pixel sensor (APS) with electronic shutter function

摘要

A pixel structure with an electronic shutter function using an active pixel sensor (APS) capable of overcoming a disadvantage of conventional pixel structures using the active pixel sensor that reset the pixels not in pixel units but in line units, and thus an electronic shutter cannot be provided, includes a plurality of pixels arrayed in a lattice pattern, a row selection decoder outputting a row selection signal to each pixel, a first line counter counting a number of lines of the pixels selected by the row selection decoder, a line reset selection decoder outputting a line reset signal to each pixel, a second line counter counting a number of lines of the pixel selected by the line reset selection decoder, a column reset selection decoder outputting a column reset signal to each pixel, a first pixel counter counting a number of the pixels selected by the column reset selection decoder, a pixel reading unit reading the pixels in pixel units, and a second pixel counter counting a number of the pixels which are read by the pixel reading unit.
