Measurement technique for the characterization of electronic still picture cameras

Electronic still picture camera systems, mostly using CCD sensors, are ever more widely used both in the photographic world and in professional measuring technique. It is therefore necessary to develop adequate measuring facilities for the characterization and quality control of high-end measuring or imaging systems. in this presentation, a versatile measuring set-up for electronic still picture cameras is described. Several standards are being developed for the characterization of electronic still picture cameras that, among other things, define the methods for measuring the spatial frequency response (SFR) using a test charr and the modulation transfer function (MTF). Exemplary results are shown for the measurement of SFR and MTF of black-and-white and colour CCD still cameras and the two properties are compared to one another.
