1. A system for determining characteristics of a target display panel, the system comprising: a plurality of filters including a first filter and a second filter, the first filter having a transmittance profile that matches a color matching function in a first wavelength range, the second filter having a transmittance profile that matches the color matching function in a second wavelength range higher than the first wavelength range; a plurality of image capturing devices including a first camera capturing a first image of a display panel via the first filter and a second camera capturing a second image of the display panel via the second filter; and a computing device operatively coupled to the plurality of image capturing devices to receive captured images including the first image and the second image from the plurality of image capturing devices, the computing device configured to determine at least one of tristimulus values for a location in the target display panel by at least: updating the first image to take into account at least a quantum efficiency of a sensor in the first image capturing device; updating the second image to take into account a quantum efficiency of a sensor in the second image capturing device; and adding a location value correlated with a brightness of the location as indicated in the updated first image and a location value correlated with a brightness of the location as indicated in the updated second image.
