Patent ID: 7245323

Claim:
An image sensing device operating in a still picture image mode and a moving picture image mode, comprising: a pixel area having a plurality of first photoelectric converters arranged in vertical and horizontal arrays to convert optical information into a first electric charge, and a first vertical transferring CCD to transfer the first electric charge from the plurality of first photoelectric converters towards the vertical direction; an optical black area having a plurality of second photoelectric converters arranged in vertical and horizontal arrays to output a second electric charge of optical black level, and a second vertical transferring CCD to transfer the second electric charge from the plurality of second photoelectric converters towards the vertical direction; a horizontal CCD for shifting the first and second electric charges transferred from the first and second vertical transferring CCDs; and a block portion for selectively blocking some of first electric charges outputted from a first area in the pixel area; and a delay means for delaying timing to transfer the second electric charge from the second vertical transferring CCD in the optical black area to the horizontal CCD by a predetermined time period, wherein the second electric charge is transferred immediately before the horizontal CCD transfers an electric charge from a second area in the pixel area excluding the first area, wherein the first and second electric charges are outputted without block operation of the block portion as picture image information and transferred to the horizontal CCD and the second electric charge from the second vertical transferring CCD is transferred to the horizontal CCD without delay operation of the delay means in the still picture image mode; and wherein the block portion selectively blocks the first electric charge in the moving picture image mode, and further wherein the second electric charge from the second vertical transferring CCD in the optical block area is transferred to the horizontal CCD by shifting timing of transferring the first electric charge from the first vertical transferring CCD in the pixel area towards the horizontal CCD and the second electric charge from the second vertical transferring CCD in the optical black area towards the horizontal CCD by the predetermined time period immediately before the some of electric charges from the second area in the pixel area excluding the first area is outputted in the moving picture image mode.
