Provided is a luminance measurement method that is able to accurately measure the luminance of each pixel even if pixel images of a display panel overlap each other on an imaging surface of a camera. In a correction data generation method according to the present invention, when pixels of a display panel 2 are imaged by a solid-state imaging camera 7, the pixels of the display panel 2 are turned on and imaged by the camera 7 such that pixel images do not overlap each other on an imaging surface of the camera 7, a central exposure factor that indicates the luminance of the central part of the pixel image as a percentage of the luminance of the entire pixel image is calculated on the basis of an output of a picture element that corresponds to the central part of the imaged pixel image, a peripheral exposure factor that indicates the luminance of the peripheral part of the pixel image as a percentage of the luminance of the entire pixel image is calculated on the basis of an output of picture elements that correspond to the peripheral part of the pixel image is calculated, all pixels of the display panel 2 are turned on and imaged by the camera 7, and the luminance of all the pixels of the display panel 2 is calculated based on this imaged image, the central exposure factor, and the peripheral exposure factor. |
