Abstract:
An unevenness correction system according to the present invention includes a panel drive circuit provided with a gamma correction circuit that performs gamma correction on an image signal input to an input interface, a gamma correction information acquisition circuit that acquires a gamma correction signal obtained through gamma correction as gamma correction information, an unevenness correction circuit that performs an unevenness correction on the gamma correction signal based on correction data, and an output interface that externally outputs the gamma correction information, and an unevenness correction apparatus provided with a pattern generator that outputs the image signal of a predetermined image to the input interface, and a control unit that generates correction data based on gamma correction information of each individual display panel input to and read by a gamma correction information reading unit from the output interface regarding the output image signal.

Claim (Index 1):
An unevenness correction system comprising a panel drive circuit and an unevenness correction apparatus,\n the panel drive circuit including:\n an image signal input unit to which an image signal is input; \n a gamma correction means configured to perform a gamma correction on the image signal input to the image signal input unit or an image processing signal obtained through image processing performed on the image signal input to the image signal input unit, such that a resultant signal has a predetermined gamma characteristic; \n a gamma correction information acquisition means configured to read a gamma correction signal obtained through the gamma correction by the gamma correction means, and acquire, as gamma correction information, the gamma correction signal or a result of comparing the gamma correction signal with the image signal input to the image signal input unit; \n an unevenness correction means configured to perform an unevenness correction on the gamma correction signal, based on correction data for reducing unevenness of a display panel; \n a D/A conversion means configured to perform a D/A conversion on an unevenness correction signal obtained through the unevenness correction by the unevenness correction means, and output a resultant signal to the display panel; and \n a gamma correction information output unit configured to externally output the gamma correction information acquired by the gamma correction information acquisition means, and \n the unevenness correction apparatus including:\n an image signal output unit connected to the panel drive circuit, and configured to output the image signal of a predetermined image as an original image signal to the image signal input unit; \n a gamma correction information input unit to which the gamma correction information output by the gamma correction information output unit is input regarding the original image signal; and\n a correction data generation means configured to generate the correction data based on the gamma correction information input to the gamma correction information input unit.
