Abstract

A display device correction method includes: obtaining, in advance, first correction data for correcting a luminance signal; performing a first transform including applying an error diffusion method to the first correction data to transform the first correction data into second correction data; performing a second transform including thinning, via a predetermined thinning method, the second correction data by removing at least one but not all of the correction data components to transform the second correction data into third correction data; performing a third transform including interpolation, via a predetermined interpolation method, using pixel data components included in the third correction data, to transform the third correction data into fourth correction data; and correcting the luminance signal using the fourth correction data. In the first transform, based on the predetermined thinning method and interpolation method, the transform is performed such that the second correction data matches the fourth correction data.
