ii) Edge Enhancement

The MTL007 uses a 5x1 Sharpening filter and a 5x1 Smoothing filter to improve edge effect. The coefficients of

latter are fixed, but the other are programmable with eight steps.

iii) Gain/Brightness Control

The MTL007 provides Gain and Brightness control to adjust the contrast and brightness of output color by

programming gain and brightness coefficients. This adjustment is applied to RGB colors individually. Auto-white

balance is possible by using this function.

iv) Gamma Correction

Gamma Correction is used to compensate the non-linearity of LCD display panel. The MTL007 contains an 8-bit

Gamma table to fix this phenomenon.

v) Color Dithering

The MTL007 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. For dithering, it

supports two methods:

Static dithering: Dithering coefficient is fixed.

Temporal dithering: Dithering coefficient will change by time.
