When a straight line is drawn between the exposure point corresponding to Dmin+0.1 density point of the density-to-logE characteristic curve of the photosensitive material and the exposure point higher by 1.8 logE than the first exposure point, the difference of density between the obtd. line and the characteristic curve is <=0.06 in the all color-sensitive recording layers in the exposure region. In each characteristic curve of the blue-sensitive emulsion layer exposed to blue light, the green-sensitive emulsion layer exposed to green light, and the red-sensitive emulsion layer exposed to red light shows that the straight line between the exposure point corresponding to Dmin+0.1 density and the the point higher by 1.8 logE than the first exposure point gives <=0.06 difference in density from the characteristic curve in that exposure region.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver halide color light-sensitive material, and more particularly to a digital film recorder which is excellent in color reproducibility, records original image data more faithfully, and further reduces flare. And a silver halide color light-sensitive material.

[0002]

2. Description of the Related Art In recent years, with the spread of personal computers and the increase in the density of recording media, there has been an increasing number of occasions in which images on a silver halide film are stored in a recording medium by a scanner or the like, processed, and output again to the silver halide film. . The method of use is to scan an image of an original color reversal film, a color negative film, or a reflection original with a scanner, store the image in a memory or a recording medium in a digital format, and electronically convert the image if necessary. Then, the scanned and changed stored image is converted into a digital film recorder (hereinafter, referred to as a digital film recorder).
It may be output by an output device and rewritten on a color reversal film or an output color negative film.

[0003] Color reversal films are often used for making slides for presentation as another application. Color negative films are often used to print post-cards by printing recorded negative images on photographic paper using a printer.

[0004] Output devices for these applications are film recorders that record images on an output film using precisely controlled light sources for red, green and blue exposure.

[0005] Generally, the light source of a film recorder is a cathode ray tube (CRT), but some film recorders are arc lamps that control output through a photoelectron tube, and there are numerous other light sources and methods in the industry. Is used.

An example of a commercially available film recorder is LFR (Lasergraphics Inc.).
Manufactured by Irvine, California, USA)
Opal (Management graphics)
Inc. Made by Minneapolis, Minneso
ta, USA), QCR (manufactured by Imapro Inc.);
Ottawa, Canada).

Currently, output devices record images on current color reversal or color negative films that are designed and optimized as standard camera photographic films. These films fall into two general classes: daylight exposure balance films and tungsten balance films. Therefore,
Many film recorders are designed to optimally write to one or both of these two classes.

When the output of the film recorder is output to a color film, particularly to a negative film, there is a possibility that the output film cannot be accurately reproduced so as to correspond to the original image data. Electronically scanning the original image,
Digitally save to memory or recording media and make electronic changes (color correction, image composition or text writing, etc.) as necessary, and then output them with a film recorder. There is a possibility that it cannot be reproduced.

[0009] This decrease in the reproducibility of the original image often occurs particularly during monochromatic exposure. In addition, the problem that the hue changes due to the difference in luminance also occurs.

[0010] These are due to several characteristics designed for standard camera photographic film (hereinafter abbreviated as "colored light-sensitive material" or simply "light-sensitive material") as the density recorded by a film recorder. Can be a factor in reducing the accuracy of For example, a curve of density vs. log E (hereinafter, “characteristic curve”) for each color-sensitive recording of a photosensitive material
), And the color enhancement effect in color recording other than white exposure (hereinafter referred to as the "inter-image effect").
It is.

In a photosensitive material having poor linearity, the hue is not constantly recorded with respect to a uniform change in luminance of a subject.
This applies not only to white exposure, but also to blue, green, or red. Similarly, in the case of a photosensitive material having a large inter-image effect, the hue is not uniformly recorded with respect to the luminance change of the original image.

Further, the output film has an output conversion table (Look-up-table, Look-up table, etc.) for adjusting to the output limit of the film recorder and the characteristics of the photosensitive material.
The LUT has a density balance that allows color development in a limited light intensity range and a density balance close to a state where an actual scene is captured by a standard camera.

What is different from a color negative film photographed by a camera is that as the light intensity of the exposed light increases, the CR
This is the generation of flare caused by the emission of the phosphor on the surface of the T tube reaching an unnecessary adjacent phosphor. This flare has a problem that it is significantly larger than actual scene shooting by a standard camera.

[0014]

<< Color Reproduction of Original Image Data >> In the above-mentioned Opal Plus digital film recorder, the step tablet for changing 8 bits (1 to 255) in 24 steps with respect to the sample 103 and the comparative sample 101 of the present invention is changed to red ( Image data created for each of R), green (G), and blue (B) was output.

The output negatives were each scanned by Nikon Cool Scan and stored as positive images. The input values (1-255) of each step of the image data for each of red, green, and blue obtained from both films are examined, and the deviation between the output film of the present invention and the comparative output film of the prior art is shown in FIG.
I put together.

From this table, it is clear that the sample 103 of the present invention has a smaller deviation and a higher reproducibility of the original image data than the comparative sample 101.

<< Reduction of Flare >> For the sample 104 and the comparative sample 101 of the present invention, LUTs were prepared for each output film using a commercially available Opal Plus digital film recorder using dedicated LUT preparation software. When creating an LUT, the LUT of the sample 104 of the present invention is used.
Exposure amount corresponding to the density of the blue-sensitive layer of the sample 104 of the present invention, wherein the maximum luminance is equal to the density of the blue-sensitive layer corresponding to -0.5 logE of the density-log E characteristic curve of the comparative sample 101. Set to. The LUT maximum luminance of the comparative film 101 was set to -0.5 logE.

The output image has 8 bits (1 to 255) as 2
A gray step tablet changing in four steps was arranged on half of the screen, and the other half was black (input value 0) to create a test image, which was output with an Opal Plus film writer.

The negative density of the non-image portion at a fixed distance from the step tablet was measured as the status M density, and the density change from D _min was compared. FIG. 4 shows the results.

From this table, it is clear that the sample 104 of the present invention has a smaller difference and a lower flare than the comparative sample 101.

3 (a), (b) and (c) show deviations of red, green and blue of output image data of a color photosensitive material sample 103 of the present invention and a comparative sample 101, respectively. The vertical axis represents the deviation between the input and output values (0 to 255) of the image data, and the horizontal axis represents the step tablet No. (1 to 24) are shown.

FIG. 4 is a curve showing a density change from _Dmin obtained from an LUT (output conversion table) created for each of the color photosensitive material sample 104 of the present invention and a comparative sample 101; The higher the concentration, the more flare. (A), (b), and (c) correspond to red, green, and blue, respectively.
