Claim One:
1. A computing device comprising: an image source configured to perform a first spatial dithering operation to generate first spatially dithered image data; and an electronic display communicatively coupled to the image source, wherein the electronic display is configured to: receive the first spatially dithered image data from the image source; determine a first refresh rate with which to display an image by comparing a local histogram and an artifact histogram, wherein the local histogram describes a first pixel grayscale distribution of the first spatially dithered image data associated with a portion of the image and the artifact histogram describes a second pixel grayscale distribution of image data expected to cause a perceivable artifact when a second spatial dithering operation is performed; and when the first refresh rate is less than a threshold refresh rate of the electronic display, perform the second spatial dithering operation on the first spatially dithered image data without performing a temporal dithering operation to generate second spatially dithered image data and display the image based at least in part on the second spatially dithered image data.
