ENGINEERING CONSIDERATIONS IN AUTOMATIC EXPOSURE CONTROL

Abstract

Results are presented of theoretical and laboratory studies in the field of automatic exposure control into a document intended for use by the designer of such systems. The automatic exposure equation is developed upon the basis of photometric analysis and each term is examined analytically. Methods are presented for the analysis of film and sensor characteristics and guidelines for the design and evaluation of automatic exposure controls are given. In addition, the results of laboratory analysis of some controls are reported as well as some significant features of an advanced design. A laboratory light source for the analysis of automatic exposure controls was developed and a description of this device is included. The appendix contains a bibliography and list of applicable standards and specifications.
