Abstract
In an image pickup apparatus having an image pickup unit, a color difference signal, which is generated from signals obtained from the visible light pixels and including the near-infrared light region, and a color difference signal, which is generated by removing the signals of the near-infrared light region, are combined, at a combination ratio that is in accordance with a saturation degree of the signal components of the visible light region, and then outputted. In this way, the hue can be reproduced with colors close to colors viewed by a person. A similar processing may be performed for the brightness signals. If the color difference signal generated by removing the signals of the near-infrared light region exhibits, for example, a negative value, then the signals of the near-infrared light region may be added again.
