Abstract
The present application discloses a mura detecting method, device and readable storage medium. The method includes obtaining an area of a target test image obtained from an original image signal where mura exists to serve as a target test area; processing the target test area to obtain a grayscale distribution; obtaining a brightness gradient distribution based on the grayscale distribution; calculating a SEMU value based on the brightness gradient distribution; and obtaining a location corresponding to the mura area based on the SEMU value. It realizes objective measurement and evaluation of halo phenomenon.
