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.

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.
