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.

Abstract: A luminance adjustment part includes a luminance determination part and a data compensation part. The luminance determination part may determine a control value for controlling luminance of a backlight assembly using linear image data that has a linear luminance profile and is generated by performing a de-gamma process on a first copy of input image data that has a nonlinear luminance profile. The compensation part may compensate pixel data that corresponds to pixels of a display panel using the control value, the pixel data being generated using a second copy of the input image data. Thus, color distortion of a displayed image as perceived by a viewer may be minimized when power consumption of a display apparatus that includes the display panel is decreased.
