Vision Basics - Mode A Binary Image Depending on the tool and operation you select, ACE Sight processes either in binary mode or greyscale mode. The processing mode is selected by ACE Sight and, in most cases, you do not have to be concerned with which type of processing is taking place. In many cases, however, you have to set threshold values for binary processing or the edge strength value for grey- scale processing. This discussion gives you an idea of how to set those values. Sample Vision Matrix shows a magnified section of the array of pixels that might be returned by a camera. In each pixel of the matrix is the greyscale value the camera has registered from the field of view.
