摘要:
A contact type image sensor device comprises a plurality of photodiodes connected in a matrix, and an equal number of blocking diodes. A capacity ratio of a photo electric part constituting the photodiodes to a diode part constituting the blocking diode is in the range of 2:1 to 30:1. Dynamic range, magnitude of the signal current, light sensitivity and after image characteristics of the image sensor are improved according to the invention.
