Abstract
In apparatus and method for generating a video signal using an LMS cone signal and an apparatus and method for restoring a video signal, a lightness signal and a chrominance signal may be generated using the LMS cone signal generated from an input image. Therefore, the generated chrominance signal may include only lightness information while the chrominance signal includes only chrominance information.
