Abstract:
A sensing pixel structure for generating a sensed image with uniform resolution is applied in a light sensor. The sensing pixel structure includes a plurality of first sensing pixels and a plurality of second sensing pixels. The location of the plurality of first sensing pixels corresponds to a center region of a lens. Each of the plurality of first sensing pixels has a first pixel area. The location of the plurality of second sensing pixels corresponds to the peripheral region of the lens. Each of the plurality of second sensing pixels has a second pixel area. The first pixel area is larger than the second pixel area, so that number of the sensing pixels corresponding to the peripheral region of the lens is larger than that corresponding to the center region of the lens. Therefore, the light sensor generates the sensed image with uniform resolution.
