Summary:
The Carlson Company has introduced two devices which employ the technique of histogram picture analysis. One device is designed for the analysis of reflection originals where the information is used to control black-and-white halftone exposures. The second is designed for the analysis of transmission or reflection color originals where the information is used for pre-scan analysis. The technique employed by these devices has the ability to evaluate the tonal quality of the original. From this information, the system is able to derive the tone reproduction curve best suited for optimum reproduction. Identification of highlights and shadow densities and correction for keyness of the subject are thus determined automatically.

The complete system is described and illustrated.
