IMAGING DEVICE AND SHADING CORRECTION METHOD

摘要

An image pick apparatus includes: an imaging element that includes a first pixel group and a second pixel group that respectively photo-electrically converts luminous fluxes that pass through different areas of a single imaging optical system, generates a first image formed by an output value of the first pixel group and a second image formed by an output value of the second pixel group, and is built therein with a pixel addition unit that adds a pixel value of the first pixel group and a pixel value of the second pixel group to generate a two-dimensional image; and an image processing section that matches a shading shape of the first image and a shading shape of the second image with a shading shape of the two-dimensional image by calculating correction coefficients stored in a memory for the output values of the first pixel group and the second pixel group.

1. An imaging device comprising:
a single imaging optical system; an imaging element that includes a first pixel group and a second pixel group that respectively photo-electrically convert luminous fluxes that pass through different areas of the imaging optical system, and generates a first image that is formed by an output value of the first pixel group and a second image that is formed by an output value of the second pixel group; and shading correction unit for making a shading shape of the first image obtained by correcting the output value of the first pixel group and a shading shape of the second image obtained by correcting the output value of the second pixel group close to a shading shape of an addition image obtained by adding the output value of the first pixel group and the output value of the second pixel group.
