Fig. 3.2.2 Scaling filter
Note: For scaling down, for both horizontal and vertical processing, MTL003 provides three methods: Pass
mode, Duplicate mode, and Bilinear mode.
3.2.2 Gain/Brightness Control
MTL003 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. MTL003 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
MTL003 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.
