APPARATUS, METHOD, AND COMPUTER-READABLE MEDIUM FOR IMAGE PROCESSING USING VARIABLE-PRECISION SHADING: abstract simplified (17715807)

• This abstract for appeared for patent application number 17715807 Titled 'APPARATUS, METHOD, AND COMPUTER-READABLE MEDIUM FOR IMAGE PROCESSING USING VARIABLE-PRECISION SHADING'

Simplified Explanation

The abstract describes a method used in computer graphics to shade a group of pixels in a specific way. The method involves shading some pixels with a higher level of detail (first precision) and others with a lower level of detail (second precision). An error value is calculated to measure the difference between the two levels of precision. If the error value is above a certain threshold, additional pixels in the group are shaded with the higher precision. If the error value is below the threshold, those additional pixels are shaded with the lower precision.

Original Abstract Submitted

There is described a method of shading a group of pixels in a fragment shader in a raster graphics pipeline. At least one first pilot pixel of the group of pixels is shaded under a first precision. At least one second pilot pixel of the group of pixels is shaded under a second precision. An error value representing a difference between the first and second pilot pixels is calculated. At least one other pixel of the group of pixels is shaded under the first precision if the error value is greater than an error threshold. The at least one other pixel is shaded under the second precision if the error value is smaller than the error threshold.
