Abstract
An image-capturing device includes: a plurality of microlenses arranged in a two-dimensional manner; a plurality of photodetectors arranged to correspond to the plurality of microlenses; an image synthesizing part that synthesizes an image at an optional image plane of a photographic optical system, based on signals from the plurality of photodetectors; and an image processing part that removes signals of other pixels from signals of pixels constituting the image synthesized in the image synthesizing part.
Claims7
An image-capturing device, comprising:
- a plurality of microlenses arranged in a two-dimensional manner;
- a plurality of photodetectors arranged to correspond to the plurality of microlenses;
- an image synthesizing part that synthesizes an image at an optional image plane of a photographic optical system, based on signals from the plurality of photodetectors;
- and
- an image processing part that removes signals of other pixels from signals of pixels constituting the image synthesized in the image synthesizing part.

An image-capturing device, comprising:
- a plurality of microlenses arranged in a two-dimensional manner so that a light flux passing through a photographic optical system is incident thereon;
- a plurality of photodetectors arranged behind the plurality of microlenses to correspond to each of the plurality of microlenses;
- an image synthesizing part that synthesizes image data of an image at an optional image plane of the photographic optical system, based on outputs of the plurality of photodetectors corresponding to each of the plurality of microlenses;
- a Fourier transforming part that performs a Fourier transform on the image data synthesized in the image synthesizing part;
- an operating unit that effectively divides a result of the Fourier transform in the Fourier transforming part, by a Fourier image of a point spread function representing an optical divergence of the light flux incident on the plurality of microlenses;
- and
- an inverse Fourier transforming part that performs an inverse Fourier transform on a result of the division in the operating unit to create target image data.
