Abstract
An image signal providing apparatus includes a signal separator which separates an inputted image signal into an upper bit and a lower bit, an upper bit image quality processor which performs image quality processing regarding an upper bit image signal, a compositor which combines the image-quality-processed upper bit image signal with a lower bit image signal and outputs the result, and a controller which controls the compositor to combine the image-quality-processed upper bit image signal with the lower bit image signal per area of the image signal based on image parameters regarding the image signal.
