Field Documentation

uint8_t NvMediaISPStatsFlickerBandSettingsV5::bandCount

Count of flicker band samples to collect per frame.

Definition at line 781 of file nvmedia_isp.h.

NvMediaISPSize NvMediaISPStatsFlickerBandSettingsV5::bandSize

Size of a single band.

This must be chosen so that

• Both width and height are even and >= 2
• Total number of accumulated pixels must be <= 2^18

Definition at line 793 of file nvmedia_isp.h.

NvMediaISPRangeFloat NvMediaISPStatsFlickerBandSettingsV5::chromaRange

Definition at line 804 of file nvmedia_isp.h.

NvMediaISPColorChannel NvMediaISPStatsFlickerBandSettingsV5::chSelect

Select the channel that is used for calculating the stats The "Luminance" channel is calculated as follows.

• In case of CFA input data, it is set to average of pixels in a single CFA block, so the value will be 0.25*R + 0.5*G + 0.25*B
• In case of RGB data it is set to 0.25*R + 0.625*G + 0.125*B
• In case of YUV data, the Y channel is used directly

Definition at line 771 of file nvmedia_isp.h.

NvMediaBool NvMediaISPStatsFlickerBandSettingsV5::enable

Enable the flicker band stats unit.

Definition at line 760 of file nvmedia_isp.h.

NvMediaISPPoint NvMediaISPStatsFlickerBandSettingsV5::offset

Offset of the first band top line (and first pixel in a line for all bands)

Definition at line 786 of file nvmedia_isp.h.

NvMediaIsp5RadialMask NvMediaISPStatsFlickerBandSettingsV5::radialMask

Elliptical mask for selecting pixels included if radialMaskEnable is set to true.

Definition at line 809 of file nvmedia_isp.h.

NvMediaBool NvMediaISPStatsFlickerBandSettingsV5::radialMaskEnable

Enable the elliptical mask for disabling pixels outside area of interest.

Definition at line 776 of file nvmedia_isp.h.

NvMediaISPRangeFloat NvMediaISPStatsFlickerBandSettingsV5::range

Select the range of pixel values to include when calculating the FB statistics In merged multi-exposure HDR image each exposure might have different characteristics (exposure time and timing) that affect FB stats; by setting these limits so that only pixels fro a single exposure are included accuracy of FB stats can be significantly improved.
