Abstract
Systems and methods for measuring characteristics of an electronic visual display are disclosed herein. A method configured in accordance with embodiments of the present technology for measuring an electronic visual display can include, for example, analyzing a region of interest (“ROI”) in an image taken of at least a portion of the electronic visual display. The method determines a center and bounds of the ROI that are, in general, floating point values rather than whole pixel locations. The method then samples whole imaging device pixels and/or fractional imaging device pixels within the bounds of the ROI and determines whether the pixels and/or fractional pixels fall within, outside, or partially within the ROI. Depending on the position of the pixels and/or fractional pixels relative to the ROI, the pixels and/or fractional pixels can be weighted and/or summed to determine an overall image characteristic for the ROI.
