Abstract
An image sensing device operates in a first and a second picture image mode. The image sensing device includes a pixel area having a first vertical transferring CCD to transfer a first electric charge converted from an optical image and a second vertical transferring CCD to transfer a second electric charge of optical black level respectively. The image sensing device includes a block portion for selectively blocking the first and second electric charge, wherein the first and second electric charges are outputted without block operation of the block portion and transferred to the horizontal CCD in the first picture image mode and wherein the block portion selectively blocks the first electric charge, and the first electric charge unblocked and the second electric charge are transferred to the horizontal CCD at different timing in a second picture image mode.
