Abstract
An image processing circuit having a delay unit U1 that delays image data Da and outputs image data as image data Db. The delay time of the delay units U1 is equivalent to the unit time of phase-rendered image signals VID1 through VID6. Upon a first difference circuit 31 subtracting image data Db from image data Da, and thus generating first difference image data Ds1, a first coefficient circuit 32 multiplies the first difference image data Ds1 by a first coefficient K1 and generates first correction data Dh1. Corrected image data Dout is generated by adding the image data Da and the first correction data Dh1. Therefore, ghosting is removed in the event of sequentially selecting blocks of batched multiple data lines to make display.
