Display and displaying method

Provided is a display device, including a first gamma correcting section which divides a first color signal that configures a given video image signal into N regions in accordance with a size, which then carries out gamma correction by using a first coefficient specific to a first color signal which...

Zusammenfassung:Provided is a display device, including a first gamma correcting section which divides a first color signal that configures a given video image signal into N regions in accordance with a size, which then carries out gamma correction by using a first coefficient specific to a first color signal which is different depending on each region, and which outputs a first correction signal, a second gamma correcting section which divides a second color signal which is different from the first color signal that configures the video image signal into N regions in accordance with a size, which then carries out gamma correction by using a second coefficient specific to the second color signal which is different from the first coefficient depending on each region, and which outputs a second correction signal, a generating section which generates drive signals having amplitude values which are different from each other depending on each of the N regions in response to the first and second correction signals from the first and second gamma correcting sections, and a display section which displays an image in response to the drive signal from the generating section, wherein gradation property of a color video image signal, in particular, of that of a low region, is improved.
