The space thermal environments of a space camera is introduced. The effects of this environments on image sensor's dimension stability and imaging quality are analyzed. On the basis of the equation of thermal balance, by the way of computer numerical simulation, remote image sensor's thermal design is performed. The analytical results indicate that its temperature distributing is improved greatly by those adopted ways and meets the need of optical design on the whole.
