A signal processing apparatus for obtaining a correlation between an A-image signal and a B-image signal which are output from an image pickup unit to be input and calculating a defocus amount includes: a near-in-focus detection unit for detecting a pixel signal in an in-focus state between the A- and B-image signals; and a correlation operation unit for operating a correlation between the A- and B-image signals, wherein the correlation operation unit has a mode for excluding the detected pixel signal in the in-focus state from a subject of the correlation operation in accordance with a detection result of the near-in-focus detection unit. |
