Image correction data generating system, image correction data generating method, and image correction data generating program for display panel using unpolished glass

A method of generating image correction data for a display panel using glass that uses an image correction data generating system which includes

• 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,
• an imager that images an output image displayed on the display panel, and
• a controller means connected to the signal generating means and the imager means,
• wherein the imager means identifies the direction of stripe unevenness of glass used in the display panel, is able to resolve an area smaller than the individual pixel sizes of the plurality of pixels of the display panel, and to be set to increase the resolution of the imager in the direction orthogonal to the direction of the stripe uneveness, the image correction data generating method comprising the controller executing:
• a step for outputting instructions for supplying a signal value shared across the entire surface of the display panel to the signal generating means;
• a step for acquiring output image data from the imager means;
• a step for computing high-pass data by applying high-pass filtering to the output image data;
• and
• a step for outputting an image correction table corresponding to the high-pass data.
