The strip of originals is transported through an evaluating station where the originals are evaluated with respect to density, color, copiability, or the like. Information indicative of the results of these evaluations is manually entered upon a strip-shaped first information carrier in spatial coordination with the originals of the strip. Thereafter, at another location, the information on the first information carrier is transferred to a second information carrier. The strip of evaluated originals is then transported to a copying apparatus and there copied in accordance with the information on the second information carrier. The strip of originals itself can be utilized as the second information carrier.

Method and apparatus for evaluating and processing a strip of originals

An exposure control for use in photographic color printing apparatus has transducers which are sensitized in the additive primary colors and scan discrete areas of an original to transmit appropriate signals to integrator circuits which, in turn, transmit signals for regulation of the ratio of primary colors in printing light. The transducers further transmit signals to circuits which determine the presence of one or more areas of predominant color in an original and modify the signals which are transmitted to the integrators, either by weakening the intensity or by preventing the transmission of corresponding transducer signals. Detection of areas of predominant color can result in generation of signals which are used to contribute to determination of the total amount of printing light.

Automatic color printing apparatus

Groups of several successive film frames of an exposed and developed photographic film are examined seriatim at an inspecting station which is located ahead of an encoding station or immediately ahead of the copying station in a photographic copying machine. An attendant examines the frames of a group at the inspecting station and actuates one or more buttons on a control panel in order to produce signals which are indicative of necessary adjustment of exposure controls for copying of certain frames. The buttons are actuated subsequent to depression of selected connecting knobs which form a row along the group of frames at the inspecting station and whose mutual spacing is less than the length of a frame; this insures that at least one knob is in register with each frame of a group at the inspecting station. The depression of a knob insures that the buttons on the control panel can transmit signals to the corresponding stage of a shift register. The stored signals are advanced through successive stages of the shift register, and the last stage transmits the signals to the encoding mechanism at the encoding station or directly to the exposure controls of the copying machine, always simultaneously with arrival of the corresponding film frame at the encoding or copying station.

Apparatus for processing developed photographic films prior to copying

The density of neighboring portions of each of a plurality of successive originals is monitored. An original is copied only if the original is comprised of at least one pair of monitored neighboring portions differing from each other in density by an amount exceeding a reference value.
