Field Documentation

NvMediaBool NvMediaISPStatsHistogramSettingsV4::enable

Holds a Boolean that enables historgram statistics.

Definition at line 270 of file nvmedia_isp.h.

NvMediaISPHdrMode NvMediaISPStatsHistogramSettingsV4::hdrMode

HDR mode.

Definition at line 325 of file nvmedia_isp.h.

unsigned char NvMediaISPStatsHistogramSettingsV4::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 320 of file nvmedia_isp.h.

unsigned char NvMediaISPStatsHistogramSettingsV4::knee[NVMEDIA_ISP_HIST_RANGE_CFG_NUM]

This is the co-effcients for the curve that defines the mapping of input pixel range to the bins.

The curve between two knee points are linearly interpolated. Knee[-1] = 0 and Knee[7] = 255(The total number of bins - 1).

Definition at line 300 of file nvmedia_isp.h.

float NvMediaISPStatsHistogramSettingsV4::offset

Offset to be applied to the input data prior to performing the bin mapping operation.

Definition at line 305 of file nvmedia_isp.h.

NvMediaISPPixelFormat NvMediaISPStatsHistogramSettingsV4::pixelFormat

Holds the pixel format on which a client wants this instance to operate.

Definition at line 273 of file nvmedia_isp.h.

unsigned char NvMediaISPStatsHistogramSettingsV4::range[NVMEDIA_ISP_HIST_RANGE_CFG_NUM]

Range of the pixel values to be considered for each zone.

The whole pixel range is divided in to 8 zones. Value 0-2 and 13-15 should not be used. The valid values and the correponding log 2 range is specified below.

3 : Range = 8
4 : Range = 16
5 : Range = 32
6 : Range = 64
7 : Range = 128
8 : Range = 256
9 : Range = 512
10 : Range = 1024
11 : Range = 2048
12 : Range = 4096

Definition at line 293 of file nvmedia_isp.h.

NvMediaRect NvMediaISPStatsHistogramSettingsV4::window

Window to construct the histogram.

Definition at line 308 of file nvmedia_isp.h.
