3.2. ADC Process
(1) COMPONENT input ADC
1) Component Gain/Offset Adjustment
- Convert to Component in Input-source
- Signal equipment displays
Impress Resolution 480P
MODEL : 212 in Pattern Generator
(480p Mode, Y : 100%, Pb/Pr : 100%)
PATTERN : 08 in Pattern Generator
(MSPG-925 Series)
- Adjust by commanding AUTO_COLOR_ADJUST
(0xF1) 0x00 0x02 instruction.
2) Confirmation
- We confirm whether “0x8E” address of EEPROM
“0xB4” is “0xAA” or not.
- If “0x8E” address of EEPROM “0xB4” isn’t “0xAA”, we
adjust once more.
- We can confirm the ADC values from “0x00~0x05”
addresses in a page “0xB4”.
