Image display device, correction data generation method, and image correction device and method, as well as image correction system

[0047]On the following pages, an image display device, correction data generation method and an image correction device and method as well as an image correction system of the invention are described in detail with reference to preferred embodiments shown in the accompanying drawings.

[0048]FIG. 1 is a conceptual diagram of an embodiment for showing the configuration of an image correction system of the invention. An image correction system 10 shown in FIG. 1 serves to generate correction data for correcting brightness unevenness of an input image inputted to a liquid crystal display 12 and correct the brightness unevenness of the input image using the generated correction data, and is constituted of a camera 14, a control device 16, a correction data calculator 26 and an image correction device 18.

[0049]The camera 14 images a pattern image displayed on the liquid crystal display 12 to generate image data of the captured image.

[0050]The camera 14 may be used to manually image a pattern
