Abstract: Provided is a correction data generation method that can generate highly accurate correction data while suppressing the influence of photon shot noise. According to the correction data generation method of the present invention, test patterns are displayed on a liquid crystal panel (2) in units of specific gradation values, the displayed test patterns are captured by a camera (3) a plurality of times for each specific gradation value, and a summed image is generated for each specific gradation value by summing a plurality of captured images of the test patterns. Based on the summed image for each specific gradation value, correction data is generated for reducing unevenness in display of the liquid crystal panel (2) through correction of a signal input to the liquid crystal panel (2).
