Claim:
1. An imaging device, comprising: a plurality of microlenses disposed in an imaging microlens area and configured to form two-dimensional images; a state detector disposed on a periphery of the imaging microlens area and configured to, on an image forming surface of the microlenses, generate images having a smaller diameter than images formed by the microlenses; and a main lens configured to guide light coming from a subject to a solid-state image sensing device, wherein a microlens array is disposed between the main lens and an image sensor, and the state detector is disposed apart from the microlens array, the image sensor configured to receive light coming from the microlens array, convert the received light into an electrical signal on a pixel-by-pixel basis, and output the electrical signals; and a corrector that calculates, using an image coming from the state detector, a correction coefficient to be used in correcting central coordinates of each of the plurality of microlenses.
