Abstract
Disclosed are an image processing method, apparatus, system and a display device, which can be allowed to perform correction processing on the grayscale of each of the pixels, without any limitation on the shape of the display panel, and have relatively high flexibility. In addition, because the pre-created correction data table has the pixel position, the marker and the correction data contained herein, the correction data are correction data integrated from displaying correction data and edge correction data if the pixel position belongs to the preset edge portion and the correction data are the displaying correction data if the pixel position is other than that belonging to the edge portion, the displaying correction data and the correction data integrated from the displaying correction data and the edge correction data are contained in the correction data table, so that the logic resource occupied in the system can be effectively reduced.
