Dead pixel detection method, electronic equipment and apparatus thereof

Abstract

The invention discloses a dead pixel detection method, electronic equipment and an apparatus thereof. The method comprises the following steps of acquiring a pixel value of a first pixel point to be detected, and a first pixel value and a second pixel value of at least two pixel points corresponding to the first pixel point to be detected; determining differential values of the pixel value of the first pixel point to be detected and the first pixel value, and the pixel value of the first pixel point to be detected and the second pixel value, and based on a relation of the differential values and a first preset threshold scope, determining whether the first pixel point to be detected is a dead pixel. Simply speaking, in an embodiment of the invention, through relations of the pixel value of the first pixel point to be detected and the pixel values of other two pixel points, whether the first pixel point to be detected is consistent with other two pixel points is determined so that a simple algorithm is used to accurately calculate whether pixel values between the adjacent pixel points are consistent and then whether the first pixel point to be detected is the dead pixel is finally determined.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to a dead point detection method, electronic equipment and a device. Background technique [0002] With the development of electronic technology, there are more and more portable electronic devices, such as mobile phones, tablet computers and other portable electronic devices. [0003] These electronic devices generally have a display screen, and when the display screen is used, it will perform dead point detection. The bad point here refers to a bad circuit due to process or design reasons, resulting in bad pixels, or due to temperature. Or due to aging and other reasons, there are dead pixels whose positions and strengths are not fixed. [0004] However, the accuracy of the current dead pixel detection method for the display screen is relatively low. Contents of the invention [0005] The embodiments of the present invention provide a dead pixel detection method,...
