Abstract:
1. A correction circuit for correcting pixel signals, comprising: a first memory for storing signals obtained by executing decimation process to a plurality of pixel signals sequentially inputted as pixel signals corresponding to a plurality of peripheral pixels positioned in the vicinity of a predetermined pixel on a predetermined screen; a calculating circuit for calculating a correction value based on an output from the first memory; a second memory for adjusting a timing of output of the correction value so as to correct a pixel signal which is for forming the predetermined pixel on a screen after the predetermined screen and which does not pass through the first memory, by the correction value corresponding to the predetermined screen; and an operating circuit for operating to correct the pixel signal which is for forming the predetermined pixel on a screen after the predetermined screen and which does not pass through the first memory, by the correction value corresponding to the predetermined screen, wherein the correction value has a value corresponding to a suppressing amount for which an influence on display gradation of the predetermined pixel by the plurality of peripheral pixels is suppressed, and wherein the suppressing is caused by a shielding member possessed by a display panel for displaying images by pixel signal.
