In a machine vision system utilizing computer processing of image data, an imaging module incorporates the image sensor as well as pre-processing circuitry, for example, for performing a background subtraction and/or a gradient calculation. The pre-processing circuitry may also compress the image information. The host computer receives the pre-processed image data and performs all other calculations necessary to complete the machine vision application, for example, to determine one or more wheel alignment parameters of a subject vehicle. In a disclosed example useful for wheel alignment, the module also includes illumination elements, and the module circuitry provides associated camera control. The background subtraction, gradient calculation and associated compression require simpler, less expensive circuitry than for typical image pre-processing boards. Yet, the pre-processing at the imaging module substantially reduces the processing burden on the host computer when compared to machine vision implementations using direct streaming of image data to the host computer.

In a system for visualizing a stereoscopic image by displaying separate video images for the left and right eyes, sub-picture data (GRD) is created for the left eye and displayed superimposed on left-eye video data (VDD) as a left-eye sub-picture without change. The right-eye sub-picture (106) is displayed by shifting the horizontal positions at which the sub-picture data created for the left eye is displayed by prescribed widths. For example, the sub picture may include a plurality of objects (GRD-1, GRD-2, . . . , GRD-N); shift widths (108, 110) of the horizontal positions of the left and right ends of the objects are individually set and stored in the sub-picture data for displaying the objects for the right eye. A sub-picture superimposed on a stereoscopic video image can thereby be rendered in the depth direction, and the data size of the sub-picture and the amount of computation required for its display can be reduced.
