Abstract
The present invention provides an image processing circuit for use in an electrooptic device having a plurality of scanning lines, a plurality of data lines, switching elements which are respectively disposed in correspondence with intersections between the scanning lines and the data lines, and pixel electrodes which are electrically coupled to the corresponding switching elements. The image processing circuit includes a delay circuit that delays externally supplied image data by a unit time so as to output delayed image data, first correction-data generation circuit that generates correction data on the basis of data which has been obtained by averaging a difference between the image data and the delayed image data every unit time, second correction-data generation circuit that generates second correction data on the basis of data which has been obtained by averaging a difference between the image data and predetermined reference data every unit time, correction circuit that generates corrected image data by correcting the delayed image data on the basis of the first correction data and the second correction data, and a phase expansion circuit which divides the corrected image da…
