Abstract

An image sensor comprising a matrix of solid-state light sensor elements each representing a unit pixel, which is capable of reading out sensor signals from respective pixels in a time series by sequentially selecting pixels on a line-by-line basis and sequentially selecting pixels in a selected line, wherein each pixel line is divided into a plurality of blocks with each block composed of the same specified number of pixels and a first scanning means sequentially reads pixel sensor signals on the block-by-block basis starting from the first block and a second scanning means reads pixel sensor signals of the readout block. The image sensor thus constructed can achieve high speed scanning of respective pixels with a minimal increase in power consumption.
