Abstract: An image display system includes a camera part and an image display part. The image display part includes a user analyzer, a gamma corrector, a gamma voltage generator, and a display panel. The camera part takes a picture of a user and generates a user image signal. The user analyzer calculates the user's viewing direction based on the user image signal. The gamma corrector generates a correction gamma value based on the viewing direction. The gamma voltage generator generates a gamma voltage based on the correction gamma value, and the display panel displays an image corresponding to the gamma voltage. Accordingly, the image display system provides the image having an optimized gamma curve to the user in real time even without a separate input from the user.

Abstract translation: 图像显示系统包括相机部分和图像显示部分。 图像显示部分包括用户分析器，伽马校正器，伽玛电压发生器和显示面板。 相机部分拍摄用户的照片并产生用户图像信号。 用户分析器基于用户图像信号计算用户的观看方向。 伽马校正器基于观察方向生成校正伽马值。 伽马电压发生器基于校正伽马值产生伽马电压，并且显示面板显示对应于伽马电压的图像。 因此，图像显示系统即使没有来自用户的单独输入，也可以实时地向用户提供具有优化的伽马曲线的图像。

Abstract: A display apparatus includes a display panel to display an image, a first frame counter to count a first number of frames during a first duration and to be reset when the first number reaches a first reference number, a second frame counter to count a second number of the frames during a second duration and to be reset when the second number reaches a second reference number, wherein the second duration occurs after and is shorter than the first duration, a level counter to hold a count value at a first count value during the first duration, to change the count value when the first frame counter is reset, and to change the count value when the second frame counter is reset, and a common voltage generator to control a level of a common voltage to correspond to the count value and to output the common voltage.
