1. For use with a sensor system that includes first sensors to acquire from a scene z-depth values and brightness data values at a first resolution, each of said first sensors occupying a first sensor area, and second sensors to acquire from said scene RGB data values at a higher second resolution, each of said second sensors occupying a second sensor area, said first and second sensors acquiring data values substantially simultaneously, a method to combine data values acquired by said first sensors with data values acquired by said second sensors such that an RGBZ image may be rendered whose resolution is higher than said first resolution, the method including the following steps: (a) dynamically correlating data values acquired by said first sensors and data values acquired by said second sensors such that depth data computed for a higher resolution pixel are affected by data values from said second sensors; and (b) up-sampling and increasing resolution of data values acquired by said first sensors such that an RGBZ model may be rendered from data values so up-sampled and increased in resolution, resolution of said RGBZ model exceeding said first resolution of said first sensors.
