Abstract
Disclosed herein is an image transmission system including a plurality of cameras and a coaxial cable for transmitting image signals from the cameras, wherein: each of the cameras includes an imaging block configured to acquire an image signal by imaging an object, a coding block configured to compression-code the image signal through intra-frame compression and inter-frame compression so as to generate a coded signal, and a signal output block configured to output the coded signal onto the coaxial cable; and the camera of interest outputs the coded signal obtained through inter-frame compression onto the coaxial cable when another of the cameras outputs the coded signal obtained through intra-frame compression onto the coaxial cable.
