GENERATION OF SUBPIXEL VALUES AND LIGHT SOURCE CONTROL VALUES FOR DIGITAL IMAGE PROCESSING, AND IMAGE PROCESSING CIRCUIT FOR PERFORMING THE GENERATION

摘要

PURPOSE: A generation of subpixel values and light source control values for digital image processing, and an image processing circuit for performing the generation are provided to dynamically the output power of a backlight unit by encoding a light source control value into the subpixel values. CONSTITUTION: A DBLC system(110) reduces power consumption. The DLBC system dynamically controls the output power of a backlight unit(140). An image processing circuit(170) generates a BL signal which controls the backlight unit. A development system(210) encodes a BL signal into sub pixel values.
