Fig. 3.2.2 Scaling filter

Note: For scaling down, for both horizontal and vertical processing, MTL001 provides three methods: Pass

mode, Duplicate mode, and Bilinear mode.

3.2.2 Gain/Brightness Control

MTL001 provides Gain and Brightness control to adjust the contrast and brightness of output color by

programming the gain and brightness coefficients. This adjustment is applied to RGB colors individually.

Auto-white balance can be achieved by using this function.

3.2.3 Gamma Correction

Gamma Correction is used to compensate the non-linearity of LCD display panel. MTL001 contains an 8/10-

bit Gamma table to fix this phenomenon. The 10-bit Gamma Table performs a better output quality, and is

commonly used together with dithering function. A traditional 8-bit Gamma correction table can also be used.

3.2.4 Color Dithering

MTL001 supports true color (8 bits per color) or high color (6 bits per color) display.

In the latter case, users can turn on dithering function to avoid artificial contour due to truncation. The

dithering function works in two modes:

¨ Static dithering: Dithering coefficient is fixed.

¨ Temporal dithering: Dithering coefficient is time dependent.
