    • In a method of driving a solid-state image sensor having an effective pixel area formed of a plurality of pixels in an array having M pixels in the vertical direction and N pixels in the horizontal direction, a scanning pixel area formed of m pixels in the vertical direction and n pixels in the horizontal direction (where M>m, N.gtoreq.n) is established within the effective pixel area, and charges stored in the pixels in the scanning pixel area are transferred by vertical CCDs driven by a first scanning pulse to a horizontal CCD and the charges transferred to the horizontal CCD are transferred by the horizontal CCD driven by a second scanning pulse to an output portion of the horizontal CCD. Further, while the driving of the horizontal CCD is stopped, the vertical CCDs are driven by a third scanning pulse having a higher frequency than the frequency of the first scanning pulse so that charges stored in the pixels in the effective pixel area outside the scanning pixel area are transferred at high speed to the horizontal CCD of which driving is stopped. The charges transferred from the vertical CCDs to the horizontal CCD at high speed are swept out of the horizontal CCD.
    • 在驱动具有在垂直方向上具有M个像素的阵列中的多个像素形成的有效像素区域和水平方向上的N个像素的固态图像传感器的方法中,在 在有效像素区域内建立水平方向(其中M> m,N> / = n)的垂直方向和n个像素,并且存储在扫描像素区域中的像素中的电荷通过由第一扫描驱动的垂直CCD传送 脉冲到水平CCD,并且转移到水平CCD的电荷被由第二扫描脉冲驱动的水平CCD传送到水平CCD的输出部分。 此外,当水平CCD的驱动停止时,垂直CCD由具有比第一扫描脉冲的频率更高的频率的第三扫描脉冲驱动,使得存储在扫描像素之外的有效像素区域中的像素中的电荷 区域以高速传送到停止驾驶的水平CCD。 从垂直CCD传输到水平CCD的电荷高速扫描出水平CCD。
