Abstract
When digital image sensors are used to capture images or videos, captured colors will have obvious differences from the colors observed by human vision. This phenomenon results from the distinctions of response curves between digital image sensors and human vision so color restoration is an essential step when images are captured by digital image sensors. In real time image systems, such as digital still cameras or video camcorders, accurate color restoration is an arduous task because of highly changeable environmental illumination. This paper introduces a color restoration method to dynamically reproduce image colors. Our proposed method employs a two‐step restoration procedure. White balance of captured images is the first step and is followed by image color correction in the second step. Our method is capable of accurate color restoration through empirical analysis and performs very fast due to low computation complexity.
