Imaging apparatus and image playing apparatus having a control device that determines whether an image plane is within a range
Abstract:
An imaging apparatus includes: a light receiving device having a micro lens array in which a plurality of micro lenses are arrayed two-dimensionally, and a plurality of photoelectric conversion elements that are provided for the plurality of micro lenses, and that outputs a plurality of photoreception signals that are obtained by receiving optical flux from an optical system via the micro lenses; a detection device that, based on the photoreception signals, detects an amount of displacement between an image plane obtained from the optical system and an image plane obtained from the light receiving device; a focal point adjustment device that performs focal point adjustment on the optical system based on the displacement amount; and a control device that, when an image plane that corresponds to the displacement amount is contained within an image plane range within which it is possible to create an image that is based on the photoreception signal, creates an image of the image plane that corresponds to the displacement amount based on a photoreception signal which is selected in accordance with the displacement amount from among the plurality of photoreception signals, and then displays this image.
