Problems solved by technology

[0011] Therefore, in the conventional technology, although the method of performing white balance is used separately for audio-visual AV signals and personal computer PC signals, there is a problem of performing white balance twice at this time.

Abstract

The present invention is image signal processing equipment and method for processing and displaying several image signals processed in different paths. The processing includes the following stages: the first stage of standardizing the image signals processed in different paths; and the second stage of performing white balance regulation with any one of the standardized image signals as reference. Thus, the picture-in-picture or double picture has the same chroma feeling and the consumer required chroma-temperature characteristic.

Description

technical field [0001] The present invention relates to an image display device, in particular to an image signal standardization method and device. Background technique [0002] Generally, flat panel display devices such as a liquid crystal display panel LCD and a plasma display panel PDP display not only audio-visual AV signals but also personal computer PC signal images. However, since the audiovisual AV signal and the personal computer PC signal are displayed through different paths, the white balance states of the audiovisual AV signal and the personal computer PC signal are different. [0003] Referring to the configuration diagram of a conventional image signal processing device shown in FIG. 1 , further details will be described. [0004] A personal computer PC signal is input to the analog-to-digital converter 102 of the image signal processing device 100 . The analog-to-digital converter 102 converts the PC signal and supplies it to the scaler 112 . [0005] The...
