AI Technical Summary

Technical Problem

In the prior art, it is necessary to manually draw test images and externally connect test boxes, which makes the test cumbersome and time-consuming, and it is impossible to directly output the test images to display the screen to deduce the sub-pixel rearrangement rules of the display screen.

Method used

A test method is provided, by obtaining at least one column of subpixels as the first image data of the test column, generating the second image data according to the target vertical resolution, and outputting it to a display screen for display, thereby realizing the subpixel rearrangement rules of the display screen without the need for an external test box.

Benefits of technology

This method does not require manual generation of test images and external test boxes, and directly receives and processes image data to the display screen for display, which significantly saves test time and testing costs.

Abstract

The invention relates to the field of image processing, and provides a test method and device, a chip and a storage medium, and the method comprises the steps: obtaining first image data with at least one column of sub-pixels as a test column; wherein the brightness of the sub-pixels in the test column is different from the brightness of the sub-pixels in the non-test column; obtaining a target vertical resolution; generating second image data with the same target vertical resolution according to the first image data; wherein the number and the column number of the test columns in the second image data are the same as those of the first image data; and outputting the second image data to a display screen for displaying. According to the method, the first image data can be directly received, the second image data is generated and displayed on the display screen, a test chart and an external test box do not need to be manually generated to test the display screen, and the test time and the test cost are saved.
