Claim One:
1. A computing device, comprising: an image source configured to generate spatially dithered image data corresponding to an image frame; and a controller communicatively coupled to the image source, wherein the controller is configured to: determine a first window in the image frame corresponding to a first portion of the spatially dithered image data; determine a first local histogram based at least in part on the first portion of the spatially dithered image data, wherein the first local histogram is configured to indicate a first grayscale distribution in the first window; determine a refresh rate with which to display the image frame based at least in part on a first overlap between the first local histogram and a first artifact histogram, wherein the first artifact histogram is configured to indicate a second grayscale distribution expected to cause perceivable artifacts; and instruct an electronic display to display the image frame using the refresh rate.
