Abstract
A display apparatus includes a plurality of pixels disposed in a matrix pattern, each of the pixels emitting light, an acquisition unit for acquiring degradation characteristics of an emission luminance of each pixel from a video signal or a signal output from the pixel, and a detection unit for detecting a boundary of pixels showing different degradation characteristics of the plurality of pixels based on the degradation characteristics acquired by the acquisition unit. A calculation unit calculates a correction amount of the video signal to the pixels in a periphery of the boundary such that the emission luminance is gently varied in the periphery of the boundary when the plurality of pixels in the periphery of the boundary detected by the detection unit are caused to emit light with a same video signal. In addition, a correction unit corrects the video signal based on the calculated correction amount, and a video image is displayed by the plurality of pixels based on the corrected video signal.
