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.

Abstract: Systems and methods for measuring spatial and angular performance of a visual display are disclosed herein. In one particular embodiment, for example, a method for measuring spatial and angular performance of a flat panel visual display includes capturing a plurality of image measurements from a visual display at a plurality of different view angles. The method also includes selecting one or more points of interest on the visual display, and calculating tristimulus values (X, Y, Z) for each point of interest at each of the plurality of view angles. The method further includes generating a view angle performance plot for the one or more selected points of interest.

Abstract: Methods and apparatuses for determining a color calibration for different spectral light inputs in an imaging apparatus measurement are disclosed herein. In one embodiment, for example, a method for determining a color calibration for different spectral light inputs in an imaging apparatus measurement can include creating a reference color calibration and a reference luminance scaling calibration for each of a plurality of colors. The method can also include measuring a reference gray value R, G, B for each color in an image measurement of the light source. The method can further include calculating an R, G, B gray value for a first pixel in each of three filtered image measurements. The method can then include calculating pixel ratio values from each of the three first pixel gray values and comparing the reference gray values to the pixel ratio values to determine which one or more reference gray values are closest to the pixel ratio values.
