Patent ID: 7277128

Claim:
An image-sensing device having a plurality of output channels comprising: a pixel area having a plurality of photoelectric converters to convert an optical image into an electric charge and a plurality of first vertical CCDs to transfer the electric charge vertically; a horizontal optical black area having a plurality of photoelectric converters to produce an electric charge in an optical black level and a plurality of second vertical CCDs to vertically transfer the electric charge disposed on the left and right borders of the pixel area; a horizontal shift area having left and right horizontal CCDs to horizontally shift the electric charge transferred from the plurality of first vertical CCDs provided on both sides of a border dividing the whole pixel area into two pixel areas and the plurality of second vertical CCDs provided in the horizontal optical black area toward the border; a vertical adder for adding a reference signal to the plurality of first and second vertical CCDs provided at a top side of the image-sensing device confronting the horizontal shift area across the pixel area and the horizontal optical black area; and an adjusting portion for adjusting a level of electric charge outputted from the left and right horizontal CCDs, wherein the pixel area and the horizontal optical black area are divided into a left channel for transferring an electric charge to the left horizontal CCD and a right channel for transferring an electric charge to the right horizontal CCD, respectively, and wherein the adjusting portion adjusts a level of electric charge from the left and right channels by using the reference signal outputted from the plurality of second vertical CCDs in the horizontal optical black area when a smear is detected from outputs of the left and right channels.
