Optical systems for high-resolution digital still cameras
Norbert Schuster · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1999
Starting from the minimum pixel number 1 k X 1.3 k for the high resolution digital photography, the camera development is dominated by the progress of matrices. Basic relations for the lens adaptation to actual detector developments are presented. Resolution losses by color interpolation and by optical ow pass filters in the one shot photography are quantified by special MTFs. Relations for he admissible blue circle, defining the depth of field in the digital photography, are deducted. Consequences of the lens adaptation to matrix properties are presented by several examples. Further developments in the semiprofessional digital still photography with nonchangeable lenses, in the digital use of classic SLR-cameras and in the professional digital still photography with bellows cameras are presented. New viewfinder concepts are discussed.
