Abstract
In a solid state imaging device in which two signals on two horizontal scanning lines are read out simultaneously for easy image enhancement, the two signals read from the two horizontal scanning lines are subtracted from each other while they are added together, and the difference signal is added to the sum signal so as to produce a video signal subject to the image enhancement. As a solid state image sensor, a MOS type image sensor as well as a CCD, CID or CC type image sensor may be used.
