Claim 13:
14. The contrast enhancement device of claim 13, wherein each of the first region data and the second region data are transferred in parallel through a first channel and a second channel, and
wherein the process circuit includes:
a first channel process circuit which performs the contrast enhancement process on the first region data transferred through the first channel based on the first region contrast enhancement coefficient in a first period in which the first region data are transferred, and performs the contrast enhancement process on the second region data transferred through the first channel based on the second region contrast enhancement coefficient in a second period in which the second region data are transferred; and
a second channel process circuit which performs the contrast enhancement process on the first region data transferred through the second channel based on the first region contrast enhancement coefficient in the first period, and performs the contrast enhancement process on the second region data transferred through the second channel based on the second region contrast enhancement coefficient in the second period.
