Abstract: A display calibration system includes: a display section subject to calibration; a correction data outputting section configured to perform a calibration process to determine, for each of the pixels of the display section, correction data for non-uniformity correction; and a first storage section configured to store reference data to be used in the calibration process. The reference data represents, for individual color patches of a first predetermined number, correspondences between RGB values and reference values. The correction data outputting section obtains, on a basis of the reference data and the measurement values of the color patches of a second predetermined number that is less than the first predetermined number, the pieces of correction data with respect to RGB values of the individual color patches of the predetermined second number. With this arrangement, it is possible to shorten a processing time of the calibration process.
