The authors have newly developed measuring methods to assess and characterize color reproduction of digital still cameras and digital video cameras which capture color images and output corresponding color information in red, green, blue digital image data, the proposed new methods incorporate spectral responsivity characteristics measurements and other characteristics measurements. They are made possible by using newly developed test charts with a dark box and a spectral light source. The proposed set up for the measurements is specially effective to eliminate the influence of automatic functions commonly equipped in digital cameras for low-end consumer use. In this paper, arrangement of measurement equipment, definition of test charts, and raw data handling are described together with worked examples.© (1998) COPYRIGHT SPIE--The International Society for Optical Engineering.
