Abstract
An image-signal transmission system comprising an imaging device, a transmitter, and a determination block, is provided. The imaging device outputs first pixel signals at a first frequency. The first pixel signals vary according to the amount of light received by pixels. A plurality of the pixels are arranged in two dimensions on a light-receiving surface of the imaging device. The transmitter transmits the first pixel signal copies separately, several times at a second frequency. The second frequency is two or more times higher than the first frequency. The determination block receives the first pixel signal copies from the transmitter. The determination block determines whether noise is mixed into the received first pixel signals by comparing the first pixel signal copies.
