Claim:
1. An image pickup apparatus comprising: an image pickup device that generates an image data by performing photoelectric conversion of object light by a plurality of pixels, and sequentially reads pixel values of the generated image data; a mechanical shutter that controls an exposure time of the image data generated by the image pickup device by controlling shielding and passing of the object light; an image pickup control section that controls, when the mechanical shutter is used, sequential reading of the pixel values from the image pickup device after the exposure time elapses and the object light is shielded, and controls, when an electronic shutter is used, sequential resetting of the pixels of the image pickup device and sequential reading of the pixel values from the pixels for which the exposure time elapses; a gain multiplying section that amplifies the pixel values of the pixels of the image data with a gain which is uniform irrespective of magnitude of the pixel values; and a control section that controls which of the mechanical shutter and the electronic shutter is to be used, and sets the gain to have different values in accordance with which of the mechanical shutter and the electronic shutter is to be used.
