Color-image reproduction apparatus
First Claim
1. A color-image reproduction apparatus for reproducing a color image on the basis of digital image data which are obtained through detection of an image by visible light detection elements capable of detecting primary colors of visible light and an infrared detection element capable of detecting electromagnetic waves including infrared rays, and in which data representing each pixel are composed of a plurality of frequency band components, the apparatus comprising:
- visible-image extraction means for extracting visible image data from the image data;
infrared-containing-image extraction means for extracting infrared-containing image data from the image data;
brightness-information extraction means for extracting brightness information from the visible image data or infrared-containing image data;
infrared-component removal means for removing an infrared component from the visible image data;
color-information extraction means for extracting color information from the visible image data from which the infrared component has been removed; and
quasi-color-image generation means for combining the brightness information and the color information so as to generate a quasi color image.

Abstract
A color-image reproduction apparatus reproduces a color image on the basis of digital image data which are obtained through detection of an image by visible light detection elements and an infrared detection element. Visible image data are extracted from the image data, and infrared-containing image data are extracted from the image data. Brightness information is extracted from the visible image data or infrared-containing image data. An infrared component is removed from the visible image data. Color information is extracted from the visible image data from which the infrared component has been removed. The brightness information and the color information are combined so as to generate a quasi color image.
