First Claim
Patent Images

1. A method of precomputing that reduces a number of computations required by a graphics pipeline, comprising:

  • capturing a first image of a plurality of images by a first image capturing device of a plurality of image capturing devices;

    capturing a second image of the plurality of images by a second image capturing device of the plurality of image capturing devices;

    defining a first image space for the first image that is a subset of the first image;

    defining a second image space for the second image that is a subset of the second image;

    capturing, by a respective image capturing device of the plurality of image capturing devices, a respective remaining image of each of the remaining plurality of images;

    defining a respective remaining image space for each of the respective remaining images that is a subset of that image;

    determining first valid pixels by analyzing pixels in the first image space for validity for processing of pixels captured by the first image capturing device;

    determining second valid pixels by analyzing pixels in the second image space for validity for processing of pixels captured by the second image capturing device;

    determining respective remaining valid pixels by analyzing pixels in each of the remaining respective image spaces for validity for processing of pixels captured by the respective image capturing devices;

    storing the first valid pixels, the second valid pixels and the respective remaining valid pixels as a valid pixel group; and

    once all valid pixels for all images spaces are determined and stored as the valid pixel group, receiving and processing, in a graphics pipeline, the valid pixel group thereby reducing the number of computations required.
