Abstract
Official abstract text for this publication.
Provided are an image composition apparatus for composing color images with black-and-white images including infrared components, and an image composition method thereof. The image composition method includes generating a first image signal with color information and a second image signal including infrared components without color information, dividing the first image signal into a brightness signal and a color signal, composing the brightness signal of the first image signal with a brightness signal of the second image signal to generate a composed brightness signal, and composing the composed brightness signal with the color signal of the first image signal to generate a color image.
First claim
Opening claim text (preview).
What is claimed is: 1. An image composition apparatus comprising: an image acquiring unit configured to acquire incident light and generate a first image signal with color information and a second image signal comprising a wider band than the first image signal and including infrared components and black-and-white components where the black-and-white components are generated based on a combination of color signals from the color information of the first image signal; an image si…
