Embodiment Construction

[0023] Preferred embodiments of the present invention are described in detail below.

[0024] Such as Figure 4 As shown, the present invention provides a method for improving the quality level of displayed images based on human visual characteristics, which is used in LCD TVs, and includes the following steps.

[0025] A1. Measure the brightness value of the brightest field.

[0026] In step A1, a luminance measuring instrument may be used to measure the luminance value of the brightest field. Use a luminance measuring instrument to measure the luminance value of the brightest field, and calculate the luminance value of each level according to the above method, for example, adjust the luminance of each level in sequence on the screen of 20 gray scales to the value of the register of the image brightness parameter, so that To meet the brightness requirements of each level is to complete the adjustment of the brightness level of the image quality based on the visual character...

Abstract

The method comprises: a1) measuring the brightness value of the brightness field with the highest brightness; a2) setting the stage numbers for the grey scales; setting the brightness value of each stage; wherein, the brightness of each stage comprises at least a two-stage increase sequence segment at its front half part; a4) according to the brightness value of each stage, setting the value of parameter register of each brightness stage. The invention can adapt the visual characteristic of human eyes to make subdivision for the grey level in dark scene so as to deeply render the details in the dark scene.

Description

technical field [0001] The present invention relates to image display of a display device, in particular to a method for improving the quality level of a displayed image based on human visual characteristics. Background technique [0002] At present, in common display devices, including televisions, computers, mobile phone monitors and other products, the display characteristics of images are almost all designed in equal proportions from bright field to dark field, and these gray levels are completely equal. The interval is designed so that the change of the image seen by people through TV and other display devices from black to gray to white is a gradual linear change. [0003] The prior art adopts a method of equalizing division from dark field to bright field when adjusting the brightness level of a display device, such as figure 1 shown. In the design of existing display devices, such as LCD TVs, most of them adjust the display effect of the entire image to different b...
