Patent ID: 7667676

Claim:
An image signal processing device used in an electro-optical device, comprising: a plurality of pixel electrodes electrically connected to a plurality of scanning lines and a plurality of data lines through switching elements provided at intersections of the plurality of scanning lines and the plurality of data lines; a counter electrode opposite to the plurality of pixel electrodes, with an electro-optical material interposed therebetween; a scanning line driving circuit to sequentially select the plurality of scanning lines; and a data line driving circuit to sample an image signal supplied through an image signal line based on a sampling signal defined by an enable signal supplied from an enable signal line that is provided in common to the plurality of data lines and to supply the sampled signal to each data line, the image signal processing device including: a specifying device to specify a correction amount of the image signal supplied to each data line based on a position of the data line with respect to an extending direction of the enable signal line; and a correcting device to correct the image signal based on the correction amount specified by the specifying device to supply the corrected image signal to the image signal line.
