Abstract
An image display apparatus adapted to display an image based on an image signal input includes: a color adjustment circuit adapted to perform one of a modification process and a correction process individually on a hue signal, a lightness signal, and a saturation signal included in first HLS signals as an image signal, and output the processed signals as second HLS signals.

An image display apparatus adapted to display an image based on an image signal input, comprising:
- a color adjustment circuit adapted to perform one of a modification process and a correction process individually on a hue signal, a lightness signal, and a saturation signal included in first HLS signals as an image signal, and output the processed signals as second HLS signals.
A method of controlling an image display apparatus, comprising:
- receiving input of image signal;
- converting first YUV signals composed of three signals of a luminance signal, a first chrominance signal, and a second chrominance signal included in the image signal input, into first HLS signals composed of three signals of a hue signal, a lightness signal, and a saturation signal;
- performing one of a modification process and a correction process individually on the hue signal, the lightness signal, and the saturation signal included in the first HLS signals;
- and
- outputting the respective signals on which one of the modification process and the correction process is performed as second HLS signals.
