The gm5060 Gamma Correction LUT may typically be programmed with an inverse function to
compensate for the gamma effect.
4.12.2 Moiré Cancellation
The “moire” effect occurs as a result of resampling (scaling) the input image to a different
display resolution. The effect occurs independantly of the scaler implementation. The effect
typically is most noticeable in regions of high switching and generally more objectionable when
realizing complex scaling ratios (eg. 800 pixels scaled to 1024 represents a scaling ratio of 32/25
and a more noticeable effect than 1024 pixels scaled to 1280 with a scaling ratio of 5/4).
By utilizing both the input and gamma LUTs, the moire effect can be reduced or eliminated.
This proprietary method is handled by G-Wizard software available from Genesis Microchip.
