APPARATUS AND METHOD FOR COMBINING IMAGES
First Claim
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 black-and-white components;
an image signal divider configured to divide the first image signal into a color signal and a brightness signal;
a brightness composer configured to combine the divided brightness signal of the first image signal with a brightness signal of the second image signal to generate a combined brightness signal; and
an image restoring unit configured to compose the combined brightness signal with the color signal of the first image signal to generate a color image.

Abstract
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.
