Abstract: An image quality adjustment apparatus obtains correction data for correcting display unevenness of a display panel by capturing an image of the display panel using a camera, and includes a moire frequency control unit that performs a control to position the display panel and the camera at a predetermined relative angle with respect to each other, an unevenness measurement unit that measures the display unevenness of the display panel based on the image captured by the camera, and a correction data generation unit that generates the correction data based on the unevenness measured by the unevenness measurement unit. Arranging the panel and the camera at the predetermined relative angle shifts a spatial frequency component of a moire pattern occurring in the image captured by the camera out of a region where a spatial frequency component of the display unevenness is present, and removes an influence of the moire pattern.
