Embodiment

[0030] The television image quality processing demonstration method of the embodiment of the present invention comprises the following specific steps:

[0031] Step 1. Turn on the demo mode and enter the demo mode state.

[0032] Step 2. The system sets parameters such as brightness, contrast and chromaticity to the standard state, and enters the normal screen.

[0033] Step 3. Turn off sharpness, noise reduction, dynamic depth of field and color space processing step by step in the normal screen, so that the screen displays the original black and white image.

[0034] Step 4. Call the special GAMMA curve to make the screen display a black and white reverse color picture.

[0035] Step 5. Turn on the sharpness and noise reduction processing, and at the same time turn off the low-pass filter channel in the sharpness and noise reduction processing, so that the screen dynamically displays the image after the image contour processing.

[0036] Step 6. Set the sharpness and noise...

Abstract

The invention relates to a digital television technology. To solve the problems that the demonstration is incomprehensive and multiple demonstration scenes need to be increased in the existing television picture quality demonstration, the invention provides a television picture quality processing demonstration method. The technical solution can be summarized as: opening a demonstration mode, demonstrating, by a system, the processing processes and effects of relevant parameters of definition, de-noising, dynamic depth of field, color space and the like in PQ (Picture Quality) processing, and finally prompting demonstration completion. The method has the advantages that special and comprehensive television picture quality processing is demonstrated to a user at one time, and the method is applicable to digital televisions.

Description

technical field [0001] The invention relates to digital television technology, in particular to digital television picture quality processing technology. Background technique [0002] At present, the phenomenon of homogeneity of TV product functions is prominent, and various manufacturers pay more attention to the special functions of TV audio and picture quality. With the development of screen display and signal processing technology, they continue to promote their own new technology features. focus. [0003] Due to the relatively subjective factors in the evaluation of image quality, in order to show the characteristics of the image quality in the product, each manufacturer has developed the function of product image quality demonstration. Currently, there are two methods for image quality demonstration processing, one is to display different image quality processing effects through split-screen presentation, and the other is to demonstrate by adding image quality process...
