The arithmetic unit 50b executes an arithmetic operation so as to add together the pixel signal from the pixel 10 (2, 2) located at the center position, the combined pixel signal derived from the pixels 10 (1, 1) and 10 (3, 1), the combined pixel signal derived from the pixels 10 (2, 1) and 10 (2, 3), the combined pixel signal derived from the pixels 10 (1, 2) and 10 (3, 2) and the combined pixel signal derived from the pixels 10 (1, 3) and 10 (3, 3). The arithmetic unit 50b outputs a sum pixel signal thus generated through the output terminal 63 of the amplification unit 60. Through these measures, a pixel signal with a weight applied to the pixel signal from the pixel 10 located at the central position can be obtained by combining signals from a plurality of pixels 10 disposed consecutively along the column direction and along the row direction in the present embodiment.
In addition to advantageous effects similar to those of the first embodiment, the following advantageous effects are achieved through the embodiment described above.
