The signal generator supplies the display panel with a signal for causing that display panel to output an image. The imager captures an output image. The imager is able to resolve an area smaller than the individual pixel sizes of a plurality of pixels. The controller is equipped with an instructing unit, an image acquirer, a high-pass filter, and a correction data generator. The instructing unit outputs instructions for supplying a signal value shared across the entire surface of the display panel to the signal generator. The image acquirer acquires output image data from the imager. The high-pass filter computes high-pass data by applying high-pass filtering to the output image data. The correction data generator outputs an image correction table corresponding to the high-pass data. ## Claims ### Claim 1 An image correction data generating system for a display panel that uses glass comprising: a signal generating means that includes a plurality of pixels and supplies the display panel that uses glass with a signal for outputting an image on that display panel;
