The EMVA 1288 Standard offers a unified method for the objective measurement and analysis of specification parameters for image sensors, particularly those used in the computer vision industry. Models for both linear and non-linear sensor responses are presented in the version 4.0 release of the standard, and are applied in the characterization of a commercial DSLR camera sensor. From image capture to analysis, this paper details the equipment, methodologies, and analyses used in the implementation of the latest standard in a controlled lab setting, serving as both a proof of concept and an evaluation of the presentation and comprehensibility of the standard from a user perspective. Measurements and analyses are made to quantify linearity, sensitivity, noise, nonuniformity, and dark current of the chosen sensor, according to the methods laid out in the EMVA 1288 standard. This paper details the realistic implementation of these processes in a controlled lab environment and discusses potential flaws and difficulties in the standard, as well as complications introduced by nonideal experimental variables.
