SLASetADCParameters_t Struct Reference

Description

Set parameters of the video analog-to-digital converter for analog inputs and color parameters for color digital cameras.

typedef struct {
u8 brightness;
u8 contrast;
u8 saturation;
u8 hue;
u8 luma1;
u8 luma2;
u8 luma3;
u8 chroma1;
u8 chroma2;
u8 mode;
u8 cameraIndex;
u16 exposure;

For the IMX412 sensor, a lower noise image is achieved by increasing exposure time first then increasing analog gain before increasing digital gain to make a bright enough image. Long exposures may result in frame blur for high speed camera or scene motion, so you may need to reduce the exposure in some cases.

Byte Offset Name Description
4brightness0 = dark, 128 = default, 255 = bright
Also used in enhancement modes, see SLASetVideoEnhancementParameters_t
5contrast0 = minimum contrast, 128 = default, 255 = maximum
Also used in enhancement modes, see SLASetVideoEnhancementParameters_t
6saturationSome Color Cameras: Color saturation. 0 = no color, 128 = default, 255= maximum
For High Bit Depth Cameras: Controls the mix between spread based and extreme based auto-gain.
  0 -> 100% spread based auto gain, controlled by brightness and contrast (high contrast image, may be saturated in some areas)
  255 -> 100% extreme (min/max) based auto-gain (shows detail for very bright or dark objects)
  128 -> Even mix of spread and extreme auto-gain methods (default)
Also used in enhancement modes, see SLASetVideoEnhancementParameters_t
