Abstract: An image processing method includes: receiving an input image signal (IIS); doubling the IIS into frames; determining a TGM mode to control an order in which gamma curves (GC) are to be applied to the doubled IIS, the GCs including first and second GCs; applying the GCs to the doubled IIS based on the TGM mode to generate a doubled, TGM-processed image signal (DTIS); correcting the DTIS to generate a corrected image signal (CIS); and dither-processing the CIS to generate an output image signal. The dither-processing of the CIS includes: performing dither-processing by sequentially applying dithering patterns (DP) of a first DP set to the CIS in association with first ones of the frames with respect to the first GC, and performing the dither-processing by sequentially applying DPs of a second DP set to the CIS in association with second ones of the frames with respect to the second GC.
