Abstract
A method and apparatus for obtaining up to one depth measurement for each pixel. A image sensing array (ISA) captures a measurement of intensity on a surface. The intensity maps to depth. Accordingly, from a single pixel, or a group of pixels without regard to the intensity distribution among the pixels in the group, a depth measurement can be obtained independently of any and/or all data captured by other pixels in the array.
