It is to be noted that the pixel signal from the pixel 10 (1, 1) and the pixel signal from the pixel 10 (3, 1) may be read out and combined at the second vertical signal line VL2 and the pixel signal from the pixel 10 (2, 1) at the central position may be read out to the first vertical signal line VL1 in the second control mode, instead. In such a case, the arithmetic unit 51 will add together and average a combined pixel signal output on the second vertical signal line VL2 and the pixel signal from the pixel 10 at the center, output on the first vertical signal line VL1.
In addition, the pixels 10 in the embodiment described above each include two selection units, i.e., the first selection unit 16 and the second selection unit 17, so as to enable adjustment of the number of pixels arranged along the column direction to be designated as combination-target pixels, their positions and the ratio of weight applied thereto. However, provided that the number of pixels arranged along the column direction to be designated as combination-target pixels is three and that the positions of these pixels are fixed, no pixel signal will be read out from the pixel 10 (1, 1) or the pixel 10 (3, 1) to, for instance, the second vertical signal line VL2, and accordingly, a pixel structure that does not include a second selection unit 17 may be adopted for the pixel 10 (1, 1) and the pixel 10 (3, 1).
