Field Documentation

float* NvMediaISPStatsLacMeasurementV4::average[NVMEDIA_ISP_LAC_ROI_NUM][NVMEDIA_ISP_COLOR_COMPONENT_NUM]

For Bayer, use NVMEDIA_ISP_COLOR_COMPONENT_[TL|TR|BL|BR] for the indices.

For YUV, use NVMEDIA_ISP_COLOR_COMPONENT_[Y|U|V]. For RGB, use NVMEDIA_ISP_COLOR_COMPONENT_[R|G|B]. Data could be negative

unsigned int* NvMediaISPStatsLacMeasurementV4::numPixels[NVMEDIA_ISP_LAC_ROI_NUM][NVMEDIA_ISP_COLOR_COMPONENT_NUM]

Holds the number of pixels per ROI per component.

Definition at line 520 of file nvmedia_isp.h.

unsigned int NvMediaISPStatsLacMeasurementV4::numWindows[NVMEDIA_ISP_LAC_ROI_NUM]

Holds the number of windows in LAC stats.

When the client calls NvIspGetStats(), NumWindows is the size of each array that the pAverage[ROI_ID][COLOR_COMPONENT] and pNumPixels[ROI_ID][COLOR_COMPONENT] pointers point to. It must be >= (NumWindowsH * NumWindowsV) in NvIspStatsLacSettings used to setup LAC. If a particular ROI is disabled ignore the measurement values corresponding to that particlar ROI. Reading values for disabled ROI will give you undefined stats values.

The LAC data will be stored in row-major order.

unsigned int NvMediaISPStatsLacMeasurementV4::numWindowsH[NVMEDIA_ISP_LAC_ROI_NUM]

Holds the number of windows in the horizontal direction.

Definition at line 506 of file nvmedia_isp.h.

unsigned int NvMediaISPStatsLacMeasurementV4::numWindowsV[NVMEDIA_ISP_LAC_ROI_NUM]

Holds the number of windows in the vertical direction.

Definition at line 509 of file nvmedia_isp.h.

NvMediaBool NvMediaISPStatsLacMeasurementV4::ROIEnable[NVMEDIA_ISP_LAC_ROI_NUM]

Holds a Boolean that specifies to ignore the stats value if a ROI is not enabled.

If using the values for disabled ROI, it will cause undefined behavior.

Definition at line 479 of file nvmedia_isp.h.

NvMediaISPPoint NvMediaISPStatsLacMeasurementV4::startOffset[NVMEDIA_ISP_LAC_ROI_NUM]

Holds the position of the top-left pixel in the top-left window.

Definition at line 484 of file nvmedia_isp.h.

NvMediaISPSize NvMediaISPStatsLacMeasurementV4::windowSize[NVMEDIA_ISP_LAC_ROI_NUM]

Holds the size of each window.

Definition at line 489 of file nvmedia_isp.h.
