发明名称 Color correction circuit and image display apparatus having same
摘要 Aspects of the invention can reduce the memory capacity constituting a lookup table while reducing the lower in color correction accuracy. A color correction circuit for correcting for color of an image to be displayed, in an image display apparatus, can include a two-dimensional lookup table. A color correction circuit section is for correcting for intensity level of at least one signal of three signals of a light-intensity signal, a first chrominance signal and a second chrominance signal that are to be inputted as an image signal representative of the image, by use of a correcting value stored in the two-dimensional lookup table, according to a combination in intensity level of the first and second chrominance signals. The two-dimensional lookup table can store, as the correcting value, correcting values corresponding respectively to combinations to be specified by an intensity level of the first chrominance signal and an intensity level of the second chrominance signal.
