Pseudo-Color Processing of Electronic Photographs

摘要

The ability to use 'black-and-white' photographic information is limited by the observer's ability to distinguish shades of gray. This Memorandum describes a 'pseudo-color' process which enhances visual discrimination by keying measured light intensity in a photograph to color. Test data obtained from the camera system of the Mariner IV were processed as an example, and the resulting pseudo-color photograph is shown. (Author)
