System for detecting executable computer image quality

Abstract

The invention relates to a computer-executable image quality detection system, which includes: a zoom symmetry test unit for testing the image zoom symmetry characteristics of an image signal; a brightness test unit for testing the brightness and chroma of an image signal Separation characteristics; distortion test unit, testing the dynamic movement characteristics of video signals; color scale test unit, testing the color purity and distinct characteristics of video signals; brightness compensation test unit, testing gamma compensation characteristics of video signals; and high and low frequency test units, testing The high-frequency and low-frequency signal presentation characteristics of the image signal can simplify and shorten the R&D test procedures and time for production personnel by executing each test unit at the same time.

Description

technical field [0001] The invention relates to a computer-executable detection system, in particular to a computer-executable image quality detection system. Background technique [0002] At present, most instrument manufacturers will provide image quality test patterns (patterns), but the patterns can only test and analyze a single image quality, and the test functions provided are limited. Therefore, in display products (such as LCD TVs or plasma TVs, etc.) etc.) It takes a long time to test during the development and production process. [0003] In the image quality inspection system of the prior art, such as Taiwan Patent Publication No. 554292, this patent discloses a method for detecting a reference position of a resolution test chart, which includes the following steps: using an image capture The device obtains an image containing a maximum dark portion in a resolution test chart; calculates the length of the maximum dark portion in the image; then divides the image...

However, the above method can only test the resolution, but cannot provide other image quality test functions

[0004] Another example is Taiwan Patent Publication No. I220689, which discloses a detection system and method for a display device, which is used with a display. The display includes a plurality of pixels, and each pixel includes a plurality of sub-pixels. The detection system mainly includes: a graphic generation device for displaying a specific pattern or color on the display; a photoelectric sensing image capture device for capturing the pattern displayed on the display into an image and outputting it; and an image processing system To process the image output by the photoelectric sensing image capture device to identify the abnormal pixels of the display; wherein the graphic generation device can control the display to sequentially generate sequence graphics of pixel subgroups, and the pixel subgroups generate different images at different times. Graphics, each pixel in each pixel subgroup of each graphic at each time only drives a certain pixel bright spot in the pixel, but the above method can only detect whether the pixels in the display are normal and flawless, It cannot provide other image quality test functions

[0005] It can be seen that the above-mentioned existing image quality detection system obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.

In order to solve the problems existing in the image quality inspection system, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general products do not have a suitable structure to solve the above problems. Obviously, it is a problem that relevant industry players are eager to solve.
