| uint32_t Rfe_WdrConfig::enable |
Flag to enable or bypass WDR Merge block TRUE: enables WDR merge block, in this case it expects two exposure inputs. FALSE: bypassed WDR Merge block, short exposure input will pass to the output.
| uint32_t Rfe_WdrConfig::useShortExpForWgtCalc |
Flag to make use of Short Exposure for the Weight calculation TRUE: Use Short exposure for weight calculcation FALSE: Use long exposure for weight calculation Refer to specs for more details

The gain at index 2 is applied to even pixel on odd line. The gain at index 3 is applied to odd pixel on odd line. only 13 bits are used
| uint32_t Rfe_WdrConfig::swb[RFE_MAX_COLOR_COMP] |
White balance gain for Short exposure input pixels The gain at index 0 is applied to even pixel on even line. The gain at index 1 is applied to odd pixel on even line. The gain at index 2 is applied to even pixel on odd line. The gain at index 3 is applied to odd pixel on odd line. only 13 bits are used
