Camera parameters can be used to set up image acquisition.
When connected to a smart camera, adjust camera-specific settings such as Exposure, Gain, Focus, Trigger, and Lighting Options.
When using the Emulator, select your image file location on the PC and use the Camera Definition menu to select which smart camera and resolution to emulate.
Gain is a multiplier. Gain varies between 0 and 1, where 0 is no gain, and 1 is full gain.
Offset is an addition or subtraction. Offset is between -255 and 255.
A high gain may be used to enhance the signal-to-noise ratio, and then a negative offset applied to re-center the signal at an intermediate gray level of 128.
Note: The SXGA sensor has only 5 levels of gain: 0, .25, .5, .75, and 1.
Important: If you are using a color camera, the Advanced Parameters dialogs will display a Color Channel dropdown menu at the top of the dialog as shown in the example below. Luminance is the default Color Channel value.
