Field Documentation

mask

uint32_t Rfe_PwlConfig::mask

16bit mask bit pattern, used to mask out any control information present in the data this field is used and will be configured even if pwl module is disabled, it gets applied first in the input pixels.

shift

uint32_t Rfe_PwlConfig::shift

3 bit configuration to perform a right shift (>>) from 0 to 7 bits, used to mask/remove out any control information present in the data this field is used and will be configured even if pwl module is disabled, it gets applied after application of mask.

offset

int32_t Rfe_PwlConfig::offset[RFE_MAX_COLOR_COMP]

DC Subtraction in S24 format Used for removing black level from input pixel this field is used and will be configured even if pwl module is disabled. It gets applied after PWL

gain

uint32_t Rfe_PwlConfig::gain[RFE_MAX_COLOR_COMP]

White balance gains for each color component Used after applying DC subtraction H3A receives DC subtracted (but not WB corrected) data

enable

uint32_t Rfe_PwlConfig::enable

Flag to enable/disable PWL, Used to uncompress sensor compressed pixel data using PWL The PWL block supports an input size from 8 - 16 bits and can support an output up to 24 bits.

uint32_t Rfe_PwlConfig::slopeShift

Slope value for shift, 7 bits are used

outClip

uint32_t Rfe_PwlConfig::outClip

Output Clip Value
