1. A video camera system having an image stabilizing circuit, comprising: a charge coupled device for receiving light signals from objects, and for producing first image signals corresponding to the light signals; a first buffer for temporarily storing said first image signals; a motion detector for receiving said first image signals and for analyzing said first image signals with second image signals previously output from said charge coupled device. to detect motion between images represented by said first and said second image signals; image shifting means for shifting a frame of said first image signals stored in said first buffer according to an output of said motion detector, and producing a shifted frame comprising a shifted portion of said image signals and a remaining portion having no image; a second buffer for storing a previous image stored in said first buffer; and image adding means for adding said shifted portion of said image signals of said shifted frame and a part of said previous image stored in said second buffer, wherein said part of said previous image stored in said second buffer replaces said remaining portion of said shifted frame having no image, said image adding means outputting output image.
