Abstract

The invention relates to an apparatus for thermal development having a receiver for receiving an imagewise exposed thermal film, an accumulator for gathering the film, a drive for advancing the film from the receiver to the accumulator, a heater located between the receiver and the accumulator for developing the film as it passes between the receiver and the accumulator, a compound image scanner for scanning the film after it has been thermally developed, the scanner having a first light source and a first sensor placed for forming a first electronic record of the image formed on the developed thermal film by reflection, a second light source and a second sensor placed for forming a second electronic record of the image formed on the developed thermal film by an opposing reflection, and a third sensor and a third light source placed for forming a third electronic record of the image formed on the developed thermal film by transmission, and a lighttight container for the receiver and the heater.

Claims

1. A light sensitive silver halide color thermal film element comprising red, green, and blue light sensitive layer units wherein the layer units form reflective images of substantially similar color on thermal development or wherein the element is substantially free of color forming components, said element having incorporated therein light insensitive organic silver salts.

2. The light sensitive element according to claim 1 further comprising a pre-exposed calibration patch.

3. A light sensitive silver halide color film element comprising red, green, and blue light sensitive layer units wherein the layer units form reflective images of substantially similar color on development or wherein the element is substantially free of color forming components, said element having an incorporated developing agent, and wherein the element further comprises a pre-exposed calibration patch.

4. A image forming method comprising the step of thermally developing an imagewise exposed light sensitive silver halide color thermal film element comprising red, green, and blue light sensitive layer units, wherein the layer units form reflective images of substantially similar color on thermal development or wherein the element is substantially free of color forming components.
