### Camera Advanced Parameters

##### Gain and Offset

Gain and Offset are the operations that are applied to the incoming video signal.

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.

Precautions for Correct Use: The SXGA sensor has only 5 levels of gain: 0, .25, .5, .75, and 1.

##### Trigger / Trigger Polarity / Torigger Delay

Refer to Trigger section.

##### Lighting mode

Refer to Lighting Option section.

##### Acquire Options

Acquire options allow you to select what to do when performing calibration.

Capture Laser Target: Focus, exposure time, and gain are automatically adjusted during calibration.

Lock Focus during Calibration: Exposure time and gain are automatically adjusted while focus is locked during calibration.

Lock Gain during Calibration: Focus and exposure time are automatically adjusted while the calibration is performed, while the gain remains fixed.

Lock Exposure during Calibration: Focus and gain are automatically adjusted while the exposure time is fixed during calibration.

##### Sensor Mode

Sensor mode allows you to change how images are acquired in order to increase capture rate (Zooming) or improve the signal-to-noise ratio (Binning).

Zooming provides a quarter-resolution centered partial-scan image. This image has a smaller field of view than the default full-scan image.

Binning provides a quarter-resolution full-scan image with the same field of view and capture rate as a full-scan image. The reduction in total pixels reduces image resolution.

Precautions for Correct Use: Zooming and Binning functionality is available for SXGA cameras only.

##### Color Channel

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.
