Patent ID: 7352395

Claim:
An image sensor, comprising: a storage means for storing a plurality of pixel data which is transmitted from a pixel array block; a switching means for delivering a first pixel data from the storage means in response to a first control signal RASS; a defect pixel repairing means which is controlled by the first, a second, a third, a fourth and a fifth control signals in order to receive surrounding pixel data having the first pixel data from the storage means and the first pixel data from the switching means and output a revised pixel data by using the first pixel data or the surrounding pixel data; and a image signal handling means for receiving the first pixel data outputted from the switching means or one of the first pixel data and the revised pixel data outputted from the defect pixel repairing means and operating an image process in order to improvement of the image sensor, wherein the switching means includes a first switching means controlled by the first control signal and an inverse first control signal in order to transmit the first pixel data to the image signal handling means and a second switching means controlled by the first control signal and the inverse first control signal in order to transmit the first pixel data to the defect pixel repairing means, wherein when the first control signal is a logical high, the first switching means is off and the second switching means is on.
