摘要： By the present invention, on the basis of information read from a magnetic recording section of a negative film (Step 200), when it is judged that there are a plurality of negative images to be exposed by the same exposure amount (the judgment in Step 212 is affirmative), a film type is identified to determine the film base density thereof, and a predetermined reference density value is added to the film base density so as to obtain a density control amount which controls the density of a print image (Steps 216 through 220). Thereafter, a color balance mean value of a large number of negative images of the same type is detected and a weighted mean value of a color balance mean value among a plurality of negative images to be exposed and the detected color balance value to obtain a color control amount (Step 222). Then, a common exposure amount is computed from the thus obtained density control amount and the color control amount (Step 224) for exposing the negative images to be exposed by the same exposure amount onto a printing paper by the common exposure amount (Step 278).

摘要： A color copying apparatus for constantly obtaining a high-quality print irrespective of a change in film characteristics due to deterioration over time and the like is disclosed. A reference image recorded on the film is photometrically measured to determine film characteristic data. After logarithmically transformed values of photometric values of an original image on one film set in a printing position have been stored, normalizing conditions are determined on the basis of average image data, and a transformation formula or table for transformation between the film characteristic data and image data is generated in correspondence with a film type. Pixels are then selected from the original image set in the printing position, and a characteristic amount of the image is calculated and is made to correspond to print characteristic data by means of the transformation formula or table. An abnormal frame is then determined by using the film characteristic data and the characteristic amount of the image, and an exposure amount is determined by setting coefficients of an exposure calculating formula as a result of the determination, so as to effect exposure control.

摘要： Digital image signal data is applied to a film recorder to produce a pseudo-negative using high gamma transparency film as the negative. The image signal data is modified before application to the film recorder to insert signal values, positive for positive transparency film and negative for negative transparency film, such that upon photographic processing of the transparency film, a negative image is produced with a positive orange mask effect. The pseudo-negative is then used to produce multiple positive print images conventional negative-working print paper.

摘要： An improved method of producing positive photographic prints in hybrid photofinishing system employing a digital image printer to produce an intermediate negative image on a non-photographic medium wherein digital data used to print the negative includes code values simulating an orange mask effect in the negative. The improvement in the method involves a reduction in the orange mask values in the digital data so as to reduce the D-max values required for digitally printing the intermediate negative thereby reducing print cost and throughput time in the process. In a further improvement, the printer code values for pixels corresponding to full white in the final image are forced to values that print as black in the negative thereby eliminating the orange mask effect for these pixels and rendering improved rendition of full white areas in the final image print.
