Abstract
An image sensor system for sensing an image of an object includes a plurality of image sensor arrays. Each array comprises photoelectric converting elements arranged to receive the object image and accumulation cells coupled to each photoelectric converting element for accumulating charges produced from the photoelectric converting element. A buffer memory cells are coupled respectively to the accumulation cells for temporarily storing the accumulated charges shifted from the accumulation cells in response to the completion of the charge accumulation in each array. A shift register is provided to receive accumulated charges from the buffer memory cells in every one of the arrays after all the arrays complete the charge accumulation. The accumulated charges stored in the shift register are then sequentially outputted.
