Abstract
A mura evaluation apparatusincludes: a mura detection unitthat acquires multiple images of a display mura present in a display area of a display device by scanning the display area while moving along a spherical surface with a preset radius; and an information processing apparatusthat generates a three-dimensional mura figure from the multiple images acquired by the mura detection unit, by associating a feature value of the display mura in each of the images with a position where the image is acquired, and generates a mura superimposed image in which the three-dimensional mura figure viewed from a designated observation angle is superimposed.
