PROBLEM TO BE SOLVED: To provide a method capable of reducing the noise components of a signal outputted from an effective pixel sufficiently, by obtaining the difference of signals of the effective pixel and a reference pixel, and to provide a method of reducing the noise components of a signal outputted from an effective pixel sufficiently, by obtaining the difference of signals of the effective pixel and an optical black pixel.SOLUTION: A signal based on the difference between the optical signal of a first pixel of an effective pixel, and the reference signal of a second pixel of an effective pixel is obtained. By using this differential signal, the output signal from an imaging device is processed. |
