The addition of these registers enables multiple use cases, not all of which are valid.
Table 6-63 highlights some possible use cases and the following MMR settings.
Name | Cfg_1.en16bitmode |
LutEn (Legacy LUT) |
Dcmpd En | Cmpd En | Linear BitWidth | CCM | Comments | |
---|---|---|---|---|---|---|---|---|
0 |
Legacy | 0 | Valid | 0 | 0 | 12 | Valid | Legacy mode but can use an optional CCM |
1 | Basic 16 bit | 1 | 0 | 0 | 0 | 16 | Valid | Enhanced mode which can use a 16 bit CFA, however no companding /decompanding. A CCM may be used. In this usecase the data is shifted down to 12 bits after CCM by the logic automatically |
2 | Basic 16 bit – inverse tone map (Visual) | 1 | 0 | 1 | 0 | 16 | Valid | Similar mode as basic 16 bit, however cmpnding LUT is used to apply an inverse gamma. CCM may be optionally used. This mode is similar to enhanced legacy visual mode but utilizes the new 16 bit CFA |
3 | 20 Bit RCCB analytics | 1 | 0 | 1 | 1 | 20 | RCB -> RGB | This is 20 bit RCCB mode. The decompanding LUT maps to 20 bit, linear CCM converts RCB to RGB and then a LOG curve is applied with companding LUT |
4 | 24 Bit RCCB analytics | 1 | 0 | 1 | 1 | 24 | RCB -> RGB | This is 20 bit RCCB mode. The decompanding LUT maps to 24 bit, linear CCM converts RCB to RGB and then a LOG curve is applied with companding LUT |
