PIXEL, PIXEL ARRAY, IMAGE SENSOR INCLUDING THE SAME AND METHOD FOR OPERATING THE IMAGE SENSOR

摘要

Disclosed are a pixel, a pixel array, an image sensor and a method for operating the image sensor. The pixel includes a photo-electro conversion unit; a first charge storage unit for storing charges converted by the photo-electro conversion unit; a first switching unit for transferring the charges from the photo-electro conversion unit to the first charge storage unit; a second charge storage unit for storing the charges converted by the photo-electro conversion unit; a second switching unit for transferring the charges from the photo-electro conversion unit to the second charge storage unit; a third switching unit for connecting the second charge storage unit with the first charge storage unit; and an output unit for outputting information about quantity of the charges stored in the first and second charge storage units. The light having the high intensity of illumination or the low intensity of illumination is sensed in the wide range.
