【発明の名称】ダイナミックレンジの広い映像を受信中の液晶ディスプレイにおけるコントラスト制御の方法、およびそのための装置

Document Type and Number:

Japanese Patent JP2001523846

Kind Code:

A

Abstract:

An apparatus and method for controlling contrast for a liquid crystal display ("LCD"), especially active-matrix LCDs, while receiving large dynamic range video data to be displayed to the user by the LCD. Contrast settings of the LCD correspond to a single look-up table from a set of different and multiple look-up tables rather than using the contrast setting of the LCD to select different voltage values from a single look-up table. The values of the reference voltages of the LCD are varied so that all shades of gray are available with each contrast selection resulting in a high image quality and a high contrast.
