Abstract
An image pickup apparatus for performing dynamic assignment of an output image in a dynamic range according to a subject. An image pickup device picks up an image of a subject, a signal processing section generates a composite image having a relatively wider dynamic range than at least either of the dynamic ranges of a long-time exposure image picked up with a relatively long exposure time by the image pickup device and a short-time exposure image picked up with a relatively short exposure time by the image pickup device, by synthesizing the long-time exposure image and the short-time exposure image A, control section compresses the composite image and dynamically varies the assignment proportion of a high luminance dynamic range to a low-middle luminance dynamic range in a dynamic range of an output image to be outputted as a video signal.
