Abstract
The present invention discloses a method and structure for accelerating image-sensing speed in a CCD image-sensing device. According to the present invention, specific shift-control electrodes (G2j−1 and G2j) are biased to serve as a block unit. After the CCD image-sensing device serially shifts out the charge packets actually corresponding to the image of a sensed object, the CCD image-sensing device can repeat the operation for image sensing without first shifting out the remaining or undesired charge packets, thereby accelerating image-sensing speed.
