Member Function Documentation
◆ DW_DEPRECATED()
| float64_t luminanceCalibrationFactor dwImageSensorStatistics::DW_DEPRECATED | ( | "This structure variable is deprecated and will be removed in the next major release. Please use the new variable in luminanceCalibrationMatrix in this struct" | ) |
(note: parameter to be deprecated starting 6.0.7.0) Holds a luminance calibration factor ( K / f^2 ) for luminance calibrated sensors.
Definition:
N = K * (t*S / (f^2)) * L N: pixel value (e.g. RGGB channel average value) K: calibration constant t: sensor exposure time in seconds (if number of exposures > 1, use long exposure time value) S: sensor gain (if number of exposures > 1, use long exposure gain value) f: aperture number (f-stop) L: Luminance
Let luminanceCalibrationFactor = K / (f^2) = N / (t*S*L)

Holds the values of active sensor temperatures in degrees Celsius.
Valid only if DW_IMAGE_FLAGS_SENSOR_TEMPERATURE is enabled. Indexes are in the range [0, numTemperatures - 1]. These values are obtained from the mapped registers of image sensor by NvSIPL and the detailed implemetation is depending on the camera module and camera driver.
