1. An imaging device, comprising:
- an imaging element that outputs an imaging result of an optical image formed on an imaging plane; and
an image processor that implements color adjustment for the imaging result using a three-dimensional look-up table;
wherein the image processor includes;
an input-side color space converter that converts a color space of the imaging result from the imaging element, and outputs a resultant imaging result as data to be processed using the three-dimensional look-up table, andan output-side color space converter that converts, using a reverse characteristic of a characteristic of the input-side color space converter, a color space of a processing result using the three-dimensional look-up table, and outputs a resultant imaging result.

Abstract
The present invention relates to an imaging device and a method of processing an imaging result in an imaging device, and is applied to e.g. an electronic still camera to thereby allow the camera to correct image quality readily and flexibly with avoiding the deterioration of the image quality effectively. In the present invention, a three-dimensional look-up table is provided and an imaging result (Y2, Cb2, Cr2) is corrected by use of the three-dimensional look-up table.

-
an imaging element that outputs an imaging result of an optical image formed on an imaging plane; and an image processor that implements color adjustment for the imaging result using a three-dimensional look-up table; wherein the image processor includes; an input-side color space converter that converts a color space of the imaging result from the imaging element, and outputs a resultant imaging result as data to be processed using the three-dimensional look-up table so that a density of grid points in the three-dimensional look-up table is high in an area requiring highly-accurate image quality correction, and an output-side color space converter that converts, using a reverse characteristic of a characteristic of the input-side color space converter, a color space of a processing result using the three-dimensional look-up table, and outputs a resultant imaging result. - View Dependent Claims (27, 28, 29, 30)
