Field Documentation

NvMediaBool NvMediaISPStatsLacSettingsV4::enable

Holds a Boolean that enables LAC statistics.

Definition at line 413 of file nvmedia_isp.h.

float NvMediaISPStatsLacSettingsV4::hdrLong

Used to determine the long exposure pixels.

Definition at line 466 of file nvmedia_isp.h.

NvMediaISPHdrMode NvMediaISPStatsLacSettingsV4::hdrMode[NVMEDIA_ISP_LAC_ROI_NUM]

HDR mode for each ROI.

If ROI is not enabled just use the first value in the array and ignore others.

Definition at line 456 of file nvmedia_isp.h.

unsigned char NvMediaISPStatsLacSettingsV4::hdrSampleMap[NVMEDIA_ISP_HDR_SAMPLE_MAP_NUM]

HDR interleave pattern Example: 1 1 1 1 1 1 0 0 1 1 0 0 1 1 1 1 OR 1 1 0 0 OR 1 1 0 0 0 0 0 0 1 1 0 0 0 0 1 1 0 0 0 0 1 1 0 0 0 0 1 1.

Definition at line 450 of file nvmedia_isp.h.

float NvMediaISPStatsLacSettingsV4::hdrShort

Used to determine the long exposure pixels.

Definition at line 461 of file nvmedia_isp.h.

NvMediaISPPixelFormat NvMediaISPStatsLacSettingsV4::pixelFormat

Indicates if pixels are in Bayer format or triplets (YUV / RGB+Y)

Definition at line 419 of file nvmedia_isp.h.

NvMediaISPRangeFloat NvMediaISPStatsLacSettingsV4::range[NVMEDIA_ISP_COLOR_COMPONENT_NUM]

The range of each color component to be used in the calculation of the average.

Range [-0.5, 1.5) for RGBY, [-1.0, 1.0) for UV

Definition at line 435 of file nvmedia_isp.h.

float NvMediaISPStatsLacSettingsV4::rgbToYGain[NVMEDIA_ISP_COLOR_COMPONENT_NUM]

rgbToYGain range [0, 1.0)

Definition at line 429 of file nvmedia_isp.h.

float NvMediaISPStatsLacSettingsV4::rgbToYOffset[NVMEDIA_ISP_COLOR_COMPONENT_NUM]

Use NVMEDIA_ISP_COLOR_COMPONENT_[R|G|B] for the indices.

This will be used to convert RGB to Y when LAC is gathered on RGB. Y = sum of (X + rgbToYOffset[X]) * rgbToYGain[X]) over X = {R, G, B}
rgbToYOffset range [-1.0, 1.0)

Definition at line 426 of file nvmedia_isp.h.

NvMediaBool NvMediaISPStatsLacSettingsV4::ROIEnable[NVMEDIA_ISP_LAC_ROI_NUM]

Enables each ROI region.

Definition at line 416 of file nvmedia_isp.h.

NvMediaISPStatsWindows NvMediaISPStatsLacSettingsV4::windows[NVMEDIA_ISP_LAC_ROI_NUM]

Windows for LAC calculation for each ROI.

Definition at line 440 of file nvmedia_isp.h.
