Claims
- 1. A method of driving a solid-state image sensor having an effective pixel area constituted by M.times.N pixels disposed in a matrix array having M pixels in the vertical direction and N pixels in the horizontal direction, wherein a scanning pixel area constituted by m pixels in the vertical direction and n pixels in the horizontal direction (where M>m, N.gtoreq.n) is established within said effective pixel area, and wherein charges stored in the pixels in said scanning pixel area are transferred by vertical CCDs driven with a first scanning pulse to a horizontal CCD and the charges transferred to said horizontal CCD are transferred by said horizontal CCD driven with a second scanning pulse to an output portion of said horizontal CCD, said method comprising the steps of:
- stopping the driving of said horizontal CCD;
- driving said vertical CCDs with a third scanning pulse having a higher frequency than the frequency of said first scanning pulse so that charges stored in the pixels in said effective pixel area which are outside said scanning pixel area are transferred at high speed to said horizontal CCD while the driving of said horizontal CCD is stopped; and
- driving said horizontal CCD with said second scanning pulse so that the charges transferred from the pixels in said effective pixel area which are outside said scanning pixel area to said horizontal CCD are transferred to said output portion of said horizontal CCD.
- 2. A method according to claim 1, wherein said output portion of said horizontal CCD is held in a reset state for a predetermined period so that the charges transferred from the pixels in said effective pixel area which are outside said scanning pixel area to said horizontal CCD are swept out.
