Quick Focus

Quick Focus is designed to quickly locate the focus setting for an object in the field of view. This is accomplished with minimal processing of the image by analyzing a histogram of the image frame. Before performing the focus calibration, a value for shutter speed and gain is determined and then the calibration process will step through the focus range of the system, capturing the required number of image frames for each focal position. A histogram is performed on each image frame and the histogram results for each focus position are averaged. When this process is completed, the data is analyzed and the optimal focus position is determined.

Note: Quick Focus may not work well for all applications. It is not recommended for applications that use very small symbols.
