Quantitative smear test method, device, storage medium and system

Abstract

The invention discloses a method, device, storage medium and system for quantitative tailing testing. The method includes: controlling the display screen under test to display a dynamic picture at a fixed display frequency; the dynamic picture includes N frames of pictures arranged in time sequence ; The pixel point of each frame picture is shifted by M pixel coordinates at the same angle with respect to the same pixel point of the previous frame picture; Control the luminance tester to sample the trailing monitoring preset in the tested display screen with the sampling frequency H The brightness of the position; according to the brightness sampled each time, calculate the brightness change value corresponding to the brightness; according to the brightness change value calculated during the period when the tested display screen completes the display of a dynamic picture, the statistics are in the visible range The number of brightness change values ​​within; according to the counted number and the sampling frequency, calculate the trailing time for a dynamic picture display to be completed. The invention quantifies the smear specification of the subjective judgment, realizes quantitative measurement of the smear problem and improves the accuracy of the smear evaluation result.

Description

Technical field[0001]The present invention belongs to the field of display of the display screen, and is specifically involved in quantization of tail tested test methods, devices, storage media, and systems.Background technique[0002]In general, if there is a turning phenomenon when the display is displayed, the tail length is too long, it will seriously affect the display of the display image, so the length of the display is often used in the performance of the display display. As an indicator of the performance of the display. When performing performance assessments for the display, you need to measure the display of the moving image of the moving image. In the prior art, the moving image displayed by the display display is mainly used to determine whether the display has a trailing phenomenon, or by observing whether the detected display has a tailing phenomenon and the length of the tail time by comparative standard prototype.[0003]In the prior art, there is a problem: the dynam...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, there are the following problems: it is subjective to judge the dynamic picture displayed on the display screen with the naked eyes of the human body, and the results of the evaluation vary from person to person, so that the accuracy of the evaluation results is not high, and the judgment process cannot be reproduced and repeated
