Abstract:
A method for detecting a mura of a virtual image in a near-eye display (110, 410, NED) and a method for demura are provided. The method for detecting a mura includes acquiring the virtual image rendered in the near-eye display (110, 410, NED); extracting a mura feature (320) of the virtual image according to a mura type; and evaluating a mura degree of the virtual image based on the mura type. The method for demura includes acquiring a mura feature (320) of a first virtual image rendered in the near-eye display (110, 410, NED); calculating a compensation factor based on the mura feature (320); and adjusting a gray scale value of the near- eye display (110, 410, NED) based on the compensation factor to obtain a second virtual image.
