Field Documentation

uint32_t NvMediaISPStatsLTMMeasurementV5::histogram[NVMEDIA_ISP5_LTM_HIST_BIN_COUNT]

Count of pixels with tone falling into each histogram bin.

Definition at line 1096 of file nvmedia_isp.h.

float_t NvMediaISPStatsLTMMeasurementV5::localAverageTone[NVMEDIA_ISP5_LTM_AVG_WIN_COUNT][NVMEDIA_ISP5_LTM_AVG_WIN_COUNT]

Average tone in local average window.

The tone values are computed by converting YUV input to tone, taking logarithm from the value and normalizing it so that dynamic range is mapped to range [0.0 .. 1.0]. See NvMediaISPStatsLocalToneMapV5 for parameters that control this process.

If no pixels contributed to a windows (either because the windows was out of image boundaries, or it was completely excluded by rectangular or elliptical masks) this value is set to zero.

uint32_t NvMediaISPStatsLTMMeasurementV5::nonMaskedPixelCount[NVMEDIA_ISP5_LTM_AVG_WIN_COUNT][NVMEDIA_ISP5_LTM_AVG_WIN_COUNT]

Number of pixels in each local average window that contributed to statistics.
