    • A color reproduction correcting system and method, and a video display device and method can reproduce original color by considering signal source and display device. Each signal source information and each display device information can be stored. The signal source and the display device, which are currently used (e.g., corrected), can be determined, for example, by a user selection. In one embodiment, the signal provided from a transmission side can be inverse gamma-corrected based on a corresponding signal source, and a colorimetric error of the inverse gamma-corrected signal is preferably corrected using corresponding signal source information and display device information. The corrected colorimetric error signal can be gamma-corrected based on a corresponding display device and then can be displayed on the corresponding display device.
    • 色彩再现校正系统和方法以及视频显示装置和方法可以通过考虑信号源和显示装置来再现原始颜色。 可以存储每个信号源信息和每个显示设备信息。 当前使用(例如,校正)的信号源和显示装置可以例如通过用户选择来确定。 在一个实施例中,从发送侧提供的信号可以基于对应的信号源进行反伽马校正,并且优选地使用相应的信号源信息和显示设备信息来校正反伽马校正信号的比色误差。 校正的比色误差信号可以基于相应的显示装置进行伽马校正,然后可以显示在相应的显示装置上。

    • Disclosed is an apparatus for correcting sound for a video display appliance and a method thereof that senses the change of the sound characteristics of the video display appliance and performs an automatic sound correction according to the change of the sound characteristics. The apparatus includes a key input unit for inputting a user's command, a sound sensing unit for sensing bass/middle/treble ranges of sound output through the speaker, a memory for storing reference sound levels of the bass/middle/treble ranges of the sound preset according to installation environment characteristics of the video display appliance, and a control unit for comparing the sound levels of the bass/middle/treble ranges of the sound sensed through the sound sensing unit with the reference sound levels of the bass/middle/treble ranges of the sound, correcting sound characteristics according to a result of comparison, and feeding the corrected sound characteristics back to the audio signal processing unit.
