Register Description
1. Contrast Adjustment (8-Bits)
The Contrast adustment is made by controlling simultaneously the gain of three internal variable gain amplifiers
through the I
2
C bus interface.
The Contrast adjustment allows you to cover a typical range of 38 dB.
2. Sub Contrast Adjustments (8-Bits
×
3)
These Adustments are used to adjust the gain of each channel controlled by the I
2
C bus. The Sub Contrast
adjustment allows you to cover a typical range of 12 dB.
