Abstract

Hybrid imaging systems combine the advantages of silver halide (AgX) and digital photography. The use of cathode ray tubes (CRT) to expose photographic materials allows an interface between the technologies of AgX and digital photography. To optimize image quality, the parameters of the CRT should fit those of the photographic film. Computer-generated test images (density step wedges, color charts, edges, or sinusodial patterns) were written onto different films. A microdensitometer with a charge coupled device (CCD) camera was used to measure modulation transfer function (MTF) and Wiener spectrum for these test images. The color transformation was determined by spectrophotometric measurements. The effect of the CRT film recorder on modulation transfer, noise, and color reproduction is discussed.
