NvMediaISPStatsLTMSettingsV5 Struct Reference

Detailed Description

Defines the settings to use for Local tone mapping statistics for ISP version 5.

Local tone mapping parameters depend on statistics gathered from previous frames by the LTM sub block. It provides a global tone histogram with 128 bins and local average statistics for configurable 8x8 windows. Both of these support rectangular and elliptical masks to block certain image areas from statistics gathering.

Field Documentation

NvMediaBool NvMediaISPStatsLTMSettingsV5::enable

Enable local tonemapping stats.

Definition at line 1058 of file nvmedia_isp.h.

uint16_t NvMediaISPStatsLTMSettingsV5::localAvgWndHeight

Height of local average statistics window in pixels.

Value must be even. See LocalAvgWidth documentation for recommendations on selecting value

Definition at line 1084 of file nvmedia_isp.h.

uint16_t NvMediaISPStatsLTMSettingsV5::localAvgWndWidth

Width of local average statistics window in pixels.

Value must be even. Value should be selected so that the 8x8 grid of windows covers whole active image area, i.e. that 8 x StatsLocalAvgWndWidth >= image width. Also, the window should be roughly rectangular.

Radial mask used to restrict statistics calculation.

Definition at line 1070 of file nvmedia_isp.h.

NvMediaBool NvMediaISPStatsLTMSettingsV5::radialMaskEnable

Enable radial mask to restrict image area used for statistics.
