Dynamsoft.DWT.EnumDWT_CameraControlProperty

Label Value Description
CCP_PAN 0 Specify the pan in degrees. Values range from –180 to +180. By default, it's 0. Positive values are clockwise from the origin (the camera rotates clockwise when viewed from above), and negative values are counterclockwise from the origin.
CCP_TILT 1 Specify the tilt in degrees. Values range from –180 to +180. By default, it's 0. Positive values point the imaging plane up, and negative values point the imaging plane down.
CCP_ROLL 2 Specify the roll in degrees. Values range from –180 to +180. By default, it's 0. Positive values cause a clockwise rotation of the camera along the image-viewing axis, and negative values cause a counterclockwise rotation of the camera.
CCP_ZOOM 3 Specify the zoom in millimeters. Values range from 10 to 600, and the default is specific to the device.
CCP_EXPOSURE 4 Specify the exposure in log base 2 seconds. In other words, for values less than zero, the exposure time is 1/2^n seconds, and for values zero or above, the exposure time is 2^n seconds. For example: -3 means 1/8 second, -2 means 1/4 second, 0 means 1 second, 2 means 4 seconds, etc.
CCP_IRIS 5 Specify the iris in units of fstop* 10.
CCP_FOCUS 6 Specify the focus in millimeters which is the distance to the optimally focused target. The range and default value are specific to the device.

Dynamsoft.DWT.EnumDWT_VideoProperty

Label Value Description
VP_BRIGHTNESS 0 Specify the brightness. For NTSC, the value is expressed in IRE units * 100. For non-NTSC sources, the units are arbitrary, with zero representing blanking and 10, 000 representing pure white. Values range from –10, 000 to 10, 000.
VP_CONTRAST 1 Specify the contrast which is expressed as the gain factor * 100. Values range from zero to 10, 000.
VP_HUE 2 Specify the hue which is expressed in degrees * 100. Values range from -180, 000 to 180, 000 (-180 to +180 degrees).
VP_SATURATION 3 Specify the saturation. Values range from 0 to 10, 000.
VP_SHARPNESS 4 Specify the sharpness. Values range from 0 to 100.
VP_GAMMA 5 Specify the gamma which is expressed as gamma * 100. Values range from 1 to 500.
VP_COLORENABLE 6 Specify the color-enable setting. It's either 0 (off) or 1 (on).
VP_WHITEBALANCE 7 Specify the white balance, as a color temperature in degrees Kelvin. The range of values depends on the device.
VP_BACKLIGHTCOMPENSATION 8 Specify the backlight compensation setting. It's either 0 (off) or 1 (on).
VP_GAIN 9 Specify the gain adjustment. Zero is normal. Positive values are brighter and negative values are darker. The range of values depends on the device.
