Weighted normalized automatic white balancing
Granted: September 6, 2022
Patent Number:
11436704
In order to more accurately white balance an image, weightings can be determined for pixels of an image when computing an illuminant color value of the image and/or a scene.

Patent Number:
11328112
In order to expedite testing (such as silicon chip testing), a test pattern that indicates a timing, order, and frequency (e.g., speed) of signals sent during the test may be divided into different portions. Also, a frequency at which each portion of the test pattern is to be run is determined. Each portion is run at a frequency that can be supported by only that portion. As a result, the slowest portion of the test pattern only limits the frequency at which its portion is run, while…
