IMAGE SENSOR

摘要

PURPOSE: An image sensor is provided to prepare an error correction and sampling unit connected in thermal units of a plurality of cyclic analog-digital converters(CADC), thereby performing error correction and a sampling operation at low speed. CONSTITUTION: A plurality of pixels(210) of the same thermal is connected to a plurality of CADCs. A plurality of CADCs converts a reset level and a signal level outputted from one of a plurality to pixels into M(N-1) bit. An error correction and sampling unit(230) is connected to a plurality of CADCs in a thermal unit. [Reference numerals] (AA,BB,CC,DD) Error correction and sampling unit
