CONTACT IMAGE SENSOR

摘要

The image sensor for reducing the wire bonding between a pixel bit and a driving unit in a image processing system comprises an optical sensing unit (30) for sensing an optical signal by a main scanning pulse from the driving unit (10) of the image processing system, a switching unit (40) switched according to the quantity of electric charge of the current detection signal from the unit (30) to transmit the current detection signal to a reader unit (20) of the image processing system and a reset unit (50) for bypassing the electric charge stored in the switching unit (40) by the main scanning pulse from the driving unit (10).
