Exposure control system for continuous tone electrophotographic film |
摘要 |
An exposure control system which permits accurate reproduction of optical density levels on a final image is characterized by a dynamically corrected look-up table. The look-up table is used to calculate each desired exposure intensity level for each image pixel on the basis of data obtained during the exposure and development of an immediately preceding image.
