Abstract
A device, system, and method are provided for processing an output of a color camera, such that the color camera may be used to measure color uniformity and resolution of an optical system. The processing includes converting an output of the color camera into an XYZ color space using a conversion matrix. The conversion matrix is generated by capturing color images and colorimeter measurements of three different wavelength ranges of light. The processing also includes overcoming the deBayering effect of the color camera to measure a resolution of the optical system using an optical test target displayed by the optical system. The optical test target has a uniform appearance along a direction of homogeneity. The resolution is determined based on a one-dimension image generated by performing a mathematical operation along the direction of homogeneity.
