Image transmission system and image transmission method

摘要

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.

1. An image transmission system, comprising:
a coaxial cable; and a plurality of cameras, each of said plurality of cameras including:
an imaging circuit that acquires an image signal by imaging an object,a coding circuit that generates a coded signal by compression-coding said image signal through one of intra-frame compression or inter-frame compression,a signal output circuit that outputs said coded signal onto said coaxial cable, and a synchronous signal generation circuit of a first camera of said plurality of cameras generates a synchronous signal that is transmitted to a second camera of the plurality of cameras, wherein said second camera outputs said coded signal, obtained through intra-frame compression, onto said coaxial cable after a predetermined time period following receipt of said synchronous signal from said first camera.
