Abstract
Abstract An automatic portraiture printer control system includes a camera system which exposes a frame of a photosensitive medium to an image. At generally the time of exposure, the camera system stores image information associated with each frame exposed in machine readable form. A printer control system analyzes the exposed frame to determine image color density values on a point-by-point basis. The printer control system reads the stored image information and determines proper printing parameters based upon the image information and the image color density values. The image is printed on photographic print paper based upon the printing parameters.
