Image sensor driving device with noise reduction circuits |
摘要 |
Image signals of an original is obtained from a plurality of image sensors and are successively supplied to an output terminal. A switching element is provided for resetting the previous image signal, which adversely causes to produce noises. An image sensor driving device according to the invention is to cancel the noises by the provision of a noise accumulating circuit and a subtracting circuit for subtracting the noises as accumulated in the noise accumulating circuit from the image signal on which the noises are superimposed.
