Abstract

PROBLEM TO BE SOLVED: To eliminate the need of color adjustment operation by a person and to always form a color picture with constant finish and excellent color reproduction by setting the chroma reproduction index of the color reproduction to be equal to or over a specified percentage and setting the Wyszecki index to be equal to or under a specified value. SOLUTION: On a color CRT 121, a positive picture in which a reference picture is simultaneously fit by the side of a gray picture being a memory color is displayed. Then, it is compared and examined whether the memory color, for example, the gray picture and the color of the displayed reference image (gray) of a film are matched with each other or not. When they are not matched, a keyboard 131 is operated to be inputted so that the color density of two pictures are matched with each other. At this time, the chroma reproduction index of the color reproduction is set to be >=70% and the Wyszecki index is set to be <=10. When the chroma reproduction index of the color reproduction is <=70%, not only the reproduction of a primary color but also the reproduction of a skin color become worse. Besides, images quality is deteriorated. When, the Wyszecki index is over 10, the faithfullness of the color reproduction when an illuminated object is photographed is impaired.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color image forming method capable of vividly and faithfully reproducing a color image on a display. Further, the present invention relates to an image forming apparatus (display apparatus) that does not require human color adjustment and always obtains a fixed finish.

[0002]

2. Description of the Related Art Various techniques have been studied and developed for the purpose of making color photographs vivid and faithful. Among them, a method of adjusting color balance in a color print, which is developed based on the principle by Evans's research that the color of the entire screen becomes gray when mixed, is well known.

The Evans method has largely solved the problem of color balance, but is still insufficient. In this method, a standard negative is used, and color correction is performed on the density difference between the negative density to be printed and the standard negative (for example, the exposure amount determination formula in JP-A-64-77041 can be used). However, since this method is characterized by a high statistically acceptable rate for various subjects, for example, if there is a bright primary color in a part of the screen, the entire screen will be affected by that color. In some cases, the color of the complementary color of the primary color is faintly dyed, and the quality of the image is deteriorated. For example, the face of a person dressed in red may be finished in cyan, or the road may become magenta when shooting a green fence (color ferria by color correction). This tendency is due to, for example, masking or DIR to enable more vivid color reproduction.
It becomes more remarkable as the multilayer effect by the coupler is increased.

Further, the difference in color temperature of the light source at the time of photographing, the difference in quality of photographing light such as photographing under a light source having an illegal energy distribution such as a fluorescent lamp or a mercury lamp, the aged change due to heat and humidity of the photosensitive material, and the developing condition It is known that the deviation of the color reproducibility is caused by the variation of the above. However, such a deviation of the color reproducibility cannot be sufficiently solved only by applying the above statistical principle.

Therefore, in order to prevent these problems, so-called verification work is carried out, in which a human observes the film screen in advance and predicts the occurrence of color ferria and corrects it in advance. There is a difference in technology, causing problems such as color changes when reprinting. That is,
Even if you shoot the same scene, the color tone will differ depending on the color developing station where you develop, or you will not be able to obtain the same color print even if you request the color negative film once developed and printed again to the same color developing station, etc. The problem of color reproducibility, which is the most important in image quality, has not been solved yet. This is because it does not guarantee that the technology developed will be available on-site, that is, with the print finish normally obtained in color laboratories. In other words, if a person pays close attention and repeats color adjustment many times to achieve the best finish, the effect of that technology can be obtained, but there are cases where the effect is not obtained with an unattended automatic color printer. is there. Many devices and methods have been developed that allow humans to perform automatic tests using machines, but they are not yet fully satisfactory.

Before the Evans method was adopted, in order to adjust the color balance in color printing, a standard patch was printed on the last portion of the negative film before the development processing, each density was measured, and the development processing was performed. In some cases, a method to correct the fluctuation of the film and the sensitivity balance of the film was adopted. However, this method does not include photographing light quality, and if only such correction is performed, the effectiveness is low and there is a problem. On the other hand, a method has been proposed in which an illumination light source is imprinted between shooting frames with a camera and printing is performed so that the part has a constant color (for example, Japanese Patent Laid-Open No. 52-133).
No. 33). However, the reflected light is not the illumination light but the reflected light of the subject, and the reflected light is the light obtained by multiplying the spectral reflectance of the subject and the illumination light, and it is inevitable to make an incorrect correction.

Further, in recent years, a method of determining the exposure amount based on an image portion or a photometric point of a specific color in a film image has been disclosed (for example, JP-A-52-156624 and JP-A-53-1233).
No. 0, JP-B-56-15492, JP-B-59-29847, JP-A-59-
220780, JP-A-61-198144, etc.). In these methods, a lot of ingenuity and complicated methods are adopted in order to find a specific color, for example, gray object in a film image. However, it is difficult to find the gray portion in the image because it is difficult to distinguish between the color of the subject and the light source in an image with different shooting light quality and film characteristics different from daylight, and therefore it is not always possible to obtain a high quality image. I have a problem that I cannot get prints.

On the other hand, as a method of displaying a film image on a display, Japanese Patent Publication No. 40-6021, Japanese Patent Publication No. 42-25220,
JP-A-53-46731, JP-A-56-62243, JP-A-56-83733
And Japanese Patent Application Laid-Open No. 62-298291 and Japanese Patent Application Laid-Open No. 63-48541. However, these are adjusted manually by trial and error, or the color is adjusted according to the printing exposure amount of the negative film, which has the same problem as described above.

There is a method of reducing the color correction by the above Evans's method as much as possible in order to eliminate the color ferria, but in this case, the color of the photograph is greatly changed due to the difference in the light quality at the time of photographing as described above. It is not possible to prevent this, as well as aging due to heat and humidity of the sensitive material,
It is also impossible to prevent the color from being changed due to a change in developing conditions.

On the other hand, in a color light-sensitive material, a method of newly providing a donor layer having a multi-layer effect for approximately achieving a negative portion of a color matching function for the purpose of increasing the saturation and hue fidelity (JP-A-61- 34541), and a method of approximating the negative part of the color matching function by a donor layer of the multi-layer effect and bringing the spectral sensitivity distribution and the positive part of the color matching function closer to each other (JP-A-62-16448). In addition, for the purpose of providing a photographic light-sensitive material which has faithful color reproducibility and whose color reproducibility does not change significantly under shooting conditions under various light sources, the spectral sensitivity of blue, green and red-sensitive silver halide emulsion layers. A method of limiting the distribution to a certain range by selecting and combining a spectral sensitizing dye and a filter dye (US Pat. No. 3,
No. 672,898), for the purpose of providing a color photographic material which has a small change in color reproducibility due to a change in color temperature of a light source at the time of photographing and has high color reproducibility, spectral analysis of blue-, green-, and red-sensitive silver halide emulsion layers. A method of defining the range of maximum sensitivity of distribution and incorporating a diffusible DIR compound (JP-A-59-131937).
No.), there is little change in color reproducibility due to changes in the color temperature of the light source at the time of shooting, and in order to provide a color photographic light-sensitive material in which high saturation and primary colors and intermediate colors are faithfully reproduced, the spectral sensitivity distribution of each emulsion layer and A method for defining the magnitude of the interlayer effect (Japanese Patent Laid-Open No. 64-19346) is known.

[0011]

However, even if a conventional photographic printing operation is carried out using the known color photographic light-sensitive materials which are said to have little color reproducibility and / or light source dependence, a pass rate which is sufficiently satisfactory. Couldn't get a color print.

Therefore, the color reproducibility shift due to the difference in the light source, the color reproducibility shift due to the color feria, the color reproducibility shift due to the aging of the photosensitive material due to heat and humidity, and the color reproducibility due to the development variation. It is desired to develop a color image forming method capable of comprehensively correcting misalignment and the like and further improving the pass rate of the obtained color image.

In particular, no system has yet been developed which can correct these color reproducibility deviations unattended and reproduce with a pass rate of almost 100%. In achieving a completely unmanned system, the question of whether or not the pass rate is 100% is very important.

In recent years, color processing has been increasing in small machines called minilabs, which are often performed at photographic material stores, but color balance adjustment requires advanced experience and skill even if there are dedicated workers. Therefore, the pass rate has not reached 100%. Although in-store processing has the advantage that customers can receive color prints quickly, in addition to the problem of insufficient acceptance rate, productivity per employee is lower than that of large-scale processing performed in a large color laboratory. However, there is a problem that the cost of color printing increases. If an unmanned method capable of obtaining a 100% pass rate color print is developed, labor costs will be eliminated, and the cost of color print will be reduced, so this effect is immeasurable. Therefore, it is further desired to develop a color image forming method capable of attaining a complete unmanned system capable of reproducing the obtained color image with a pass rate of 100%.

The same problems as described above also exist in color image formation in which a color negative film is directly displayed on a CRT. Therefore, the present invention always forms a color image with good color reproduction even in such a color image formation. To provide a way to do.

A further object of the present invention is to form a color image which is displayed on a CRT directly from the color negative film and does not require human color adjustment and always has a constant finish and good color reproduction. Image forming apparatus.

[0017]

[Means for Solving the Problems] These problems are as follows: (1) A color photographic material having a red-sensitive, green-sensitive, and blue-sensitive silver halide emulsion layer on a support is used for photographing, development processing, and color display. In the color image forming method reproduced above, the saturation reproduction index of the color reproduction is 70% or more, the Bizecky index is 10 or less, and a standard gray image is displayed on part or all of the outside of the screen of the photographic material. A color image forming method, which is characterized by selecting conditions under which the recorded image is grayed out on the display and reproducing the photographed image on the display under this condition.

(2) A standard photographic material recorded on a part or all of the outside of the photographing screen of a color photographic material having a red-sensitive, green-sensitive and blue-sensitive silver halide emulsion layer on a support before or almost at the same time as the photographing. A display device characterized by selecting a condition that makes a gray image gray and reproducing the captured image on the display under this condition. Will be solved in.

That is, in the present invention, first, in a color film / photo printing apparatus / color printing system, when the saturation reproduction index and the Bizecky index as defined below are set to 70% or more and 10 or less, respectively, It has been found that the color reproducibility deviation, especially the color reproducibility deviation due to the difference in the light source, and the color reproducibility deviation due to the color ferria can be eliminated by forming the color image by the no-color collection. In other words, it has been found that, by setting the color image forming system, a color print having a sufficiently satisfactory color reproducibility can be obtained with a high pass rate even when shooting various light sources and / or various subjects. It was issued.

The saturation reproduction index is preferably 75% or more, particularly preferably 80% or more, and the Bizecky index is preferably 8 or less, particularly preferably 5 or less. Blue when the saturation reproduction index is 70% or less,
Not only the color reproduction of the primary colors such as green and red is deteriorated, but also the reproduction of the skin color, which is the most important color for color photography, is extremely deteriorated and the image quality is deteriorated.

When the Bizecky index exceeds 10, the type of illumination light source, in particular, various fluorescent lamps, metal halide lamps, high pressure sodium lamps, HID lamps such as high pressure mercury lamps, which have been developed in response to diversification of needs in recent years, are used for illumination. The fidelity of color reproduction when a captured subject is photographed is significantly impaired. Even in sunlight, the influence of color temperature due to the sun, shade, shooting time, etc. becomes significant.

The saturation reproduction index referred to here is that the 18 colors on the Macbeth color chart were photographed with a standard white light source and proper exposure, and then reproduced on the print material according to the standard process specified for the print material, and reproduced as the original. Is reproduced on the a * b * plane, and the ratio of the area surrounded by the reproduced 18 colors to the original area is displayed in percentage.
The closer to 100%, the better the saturation reproduction.

The Bizecky index referred to here is JISZ87.
A neutral color object having the spectral energy distribution of 12 types of Bizeckey's metamers shown in 19 was photographed, 12 colors were printed so as to center on gray, and the 12 reproduced colors were printed on the a * b * plane. Reproduce and represent the standard deviation of 12 colors.

[0024]

[Equation 1]

Further, both indexes in the case of forming a color image on the display are similarly defined based on the color reproduced on the display.

When the color image forming system is set so that the saturation reproduction index and the Visecky index defined above both satisfy the above values, the reason why the sunlight, fluorescent lamp, mercury lamp, incandescent lamp,
It is not always clear whether photographs taken under various lighting such as strobe light can be obtained with excellent color reproducibility and a high pass rate. However, in the present invention, since the light source dependency is small, the value of the color correction coefficient C _j in the color image forming system is about 0.8, which is the conventional value.
It is possible to reduce it to about 1.0 to 0.0 to 0.5, and by doing so, it is possible to completely eliminate the occurrence of color ferria.

As a result of earnest studies, a method for satisfying both the values of the saturation reproduction index and the Bizeckey index was derived. It has been found that a method satisfying both of them can be obtained only by combining at least two of the following techniques 1) to 3).

1) A technique for defining the spectral sensitivity distribution of each light-sensitive layer of a color photographic light-sensitive material and the magnitude of the inter-layer suppressing effect between the light-sensitive layers within a specific range, that is, a blue-sensitive silver halide emulsion. In the spectral sensitivity distribution S _B (λ) of the layer,

[0029]

[Equation 2]

And the magnitude of the interlayer effect is -0.15≤D _B / D _R ≤ + 0.20 -0.70 ≤D _G / D _R ≤0.00 -0.50 ≤D _B / D _G ≤ 0.00 -0.10 ≤ D _R / D _G ≤ -0.10 -0.45 ≤ D _G / D _B ≤-0.05 -0.05 -D _R / D _B ≤ +0.35 (However, D _B / D _R is the red-sensitive layer to the blue-sensitive layer, D _G / D _R
Is a red-sensitive layer to a green-sensitive layer, D _B / D _G is a green-sensitive layer to a blue-sensitive layer, D _R / D _G is a green-sensitive layer to a red-sensitive layer, and D _G / D _B is a blue-sensitive layer to a green-sensitive layer. , D _R / D _B respectively represent the magnitude of the interlayer effect from the blue-sensitive layer to the red-sensitive layer).

The details are described in JP-A-64-19346, and the interlayer effect here is determined as follows. For example, the interlayer effect (D _R / D _G ) from the green-sensitive layer to the red-sensitive layer is first exposed stepwise by green light (Fuji Filter: BPN-55) and then by red light (Fuji Filter: SC). -60), the characteristic curve obtained by uniform exposure is expressed as the magenta density difference (Δy) between the fog density and the density at the exposure amount Q which is 1.5 larger by the log E from the exposure amount P which gives this. obtains the cyan density difference between the cyan density ([Delta] x) in the cyan density and exposure amount Q in the exposure amount P, and [Delta] x / [Delta] y, an interlayer effect from the green-sensitive layer to the red-sensitive layer (D _R / D _G) size Let's use it as a measure. The interlayer effect from the blue-sensitive layer to the red-sensitive layer can be similarly determined using blue light (Fuji Filter: BPN45).

When Δx is a negative value, the inter-layer suppressing effect is effective, and the inter-layer suppressing effect is represented by a negative value. When Δx is a positive value, the inter-layer suppression effect is not effective (cloudy), and its magnitude is represented by a positive value. Here, the spectral sensitivity distributions of the blue-sensitive layer, the green-sensitive layer and the red-sensitive layer can be obtained, for example, by appropriately combining and using spectral sensitizing dyes having the structural formulas shown below.

Regarding the achievement of the inter-layer effect, the diffusible DIR compound may be contained in only one of the blue-sensitive layer, the green-sensitive layer and the red-sensitive layer, but it is effective to obtain better color reproduction. It is preferable to contain two or more layers. In addition, if a leaving group is released due to a substantial coupling reaction with an oxidized color developing agent diffused from another layer during color development, it does not contain silver halide by itself or exhibit color sensitivity. You may make it contain in the layer which does not have.

It is also possible that a certain color-sensitive layer is divided into two or more layers, one or more layers of which contain the diffusible DIR compound and the other layers do not contain. At this time, the sensitivities of the plurality of layers may be different from each other, such as a so-called high-sensitivity layer and a low-sensitivity layer, and the color sensitivities may not be completely the same. .

Further, in order to arbitrarily change the degree of the interlayer inhibition effect, the iodine content of the emulsion may be appropriately changed, or a method may be used in which a colored coupler is added to mask unnecessary absorption of the color forming dye. A method may be used in which a color-developing dye having a different color sensitivity is intentionally mixed to increase color turbidity and cancel the interlayer suppression effect.

The compound that releases a diffusible development inhibitor or a diffusive development inhibitor precursor upon coupling with a color developing agent used herein is represented by the following formula (I), and specifically, it is described in the above publication. It is described in.

Or 2 represents Y, which represents a group capable of releasing a development inhibitor having a large diffusivity or a development inhibitor which is a group which is bonded to the coupling position of the coupler component J and is released by the reaction with the oxidation product of the color developing agent. )

2) In the color photographic light-sensitive material, a donor layer having a multi-layer effect which approximately achieves the negative portion of the color matching function is newly provided, and more preferably, the spectral sensitivity distribution and the positive portion of the color matching function are brought close to each other. That is, the center of gravity sensitivity wavelength (λ _G ) of the spectral sensitivity distribution of the green-sensitive layer is 520 nm ≤ λ _G ≤ 580 nm, and at least one cyan-sensitive red-sensitive silver halide emulsion layer is in the range of 500 nm to 600 nm. The centroid wavelength (λ _-R ) of the distribution of the magnitude of the stacking effect received from the layer is set to 500 nm <λ _-R ≤ 560 nm, and λ _G -λ _{- R} ≥ 5 nm
And more preferably the distribution S of the magnitude of the stacking effect.

Here, the red-sensitive silver halide emulsion layer is 500
The center-of-gravity wavelength λ _-R of the wavelength distribution of the magnitude of the stacking effect received from other layers in the range of nm to 600 nm can be obtained as follows.

(1) First, a red filter that transmits a specific wavelength or longer, or an interference filter that transmits only a specific wavelength so that the red-sensitive layer that develops cyan at a wavelength of 600 nm or longer is exposed and the other layers are not exposed. Is used to uniformly expose the red-sensitive layer that develops cyan to an appropriate value. (2) Then, when spectral exposure is applied, a multilayer effect of development suppression works from the blue-sensitive layer and the green-sensitive layer to give a reversal image. (3) From this inverted image, the spectral sensitivity distribution S _−R (λ) as the inverted photosensitive material is obtained. (4) Calculate the center-of-gravity wavelength (λ _-R ) of the multilayer effect using the following formula.

[0044]

(Equation 4)

S _G (λ) is a spectral sensitivity distribution curve of the green-sensitive layer, and S _G (λ) at a specific λ is obtained as a relative value. Similarly, by selecting an appropriate interference filter and covering the blue-sensitive layer and the green-sensitive layer in advance to give equal energy spectrum light, S _-B (λ), S _-G (λ)
The distribution can be obtained.

In order to obtain these spectral sensitivity distributions, known techniques, for example, selection of an appropriate sensitizing dye and fixed dyes or diffusible dyes such as yellow filters, ultraviolet absorbing filters, and ultraviolet absorbing filters may be used. Further, in order to correct the distortion of the spectral sensitivity distribution due to the absorption of light in the upper layer, the spectral sensitivity distributions of layers having the same color sensitivity (for example, the red sensitive layer) and different sensitivities may be slightly changed. Masking coupler, DIR compound,
The amount of the adsorptive antifoggant and the addition layer may be appropriately selected. In addition, a layer structure that is susceptible to the multilayer effect, for example, by lowering the silver / coupler ratio or using a low color-forming coupler, may be devised.

3) As the color paper, a coupler having a wide color reproduction range and little secondary absorption is used. For example, there is a pyrazoloazole-based magenta coupler, and among these pyrazoloazole-based couplers, imidazo [1,2-b] described in U.S. Pat.No. 4,500,630 in terms of low yellow sub-absorption of a coloring dye and light fastness. Pyrazoles are preferred,
Pyrazolo [1,5-as described in U.S. Pat. No. 4,540,654
b] [1,2,4] triazole is particularly preferred. In addition, a pyrazolotriazole coupler in which a branched alkyl group as described in JP-A-61-65245 is directly bonded to the 2, 3 or 6-position of a pyrazolotriazole ring, as described in JP-A-61-65246 , A pyrazoloazole coupler containing a sulfonamide group in the molecule, a pyrazolotriazole coupler having an alkoxyphenyl sulfonamide ballast group as described in JP-A-61-147254, and European Patent (Publication) No. 226,849 and It is preferable to use a pyrazolotriazole coupler having an alkoxy group or an aryloxy group at the 6-position as described in JP-A-294,785.

Further, a cyan coupler having a small amount of secondary absorption may be used. Specifically, it is specifically disclosed in JP-A-63-264753 and 64-552.
Nos. 64-554, 64-555, 64-556 and the like can be used. Also, a short-wavelength yellow coupler can be used. Specifically,
Those described in 63-123047 and 63-231451 can also be used.

As a result of various studies, the present inventor has described above 1) to
It is not possible to set both the saturation reproduction index and the Bizeckey index to the values according to the present invention by only one of the techniques of 3), and by combining these, the shape of the spectral sensitivity distribution for satisfying the above conditions is further formed. It was found that the direction and magnitude of the stacking effect, the spectral sensitivity distribution of the donor layer, and the magnitude of the stacking effect from the donor layer can be obtained by precise experiments. In a color image forming system that satisfies both the saturation reproduction index and the Vizeckey index, if one of the above conditions is moved, at least one of the two indices may not immediately be satisfied, and the two conditions may not meet each other. Since they are related to each other, it is not possible to determine each independently. However, those skilled in the art can easily set each condition in the above technique so as to satisfy the above-mentioned index together. If the two indexes are set so as to satisfy the above values, for example, by appropriately combining the above techniques and setting the color photographic material and the color print material that satisfy the above indexes, the photographic conditions can be obtained without color correction. It is possible to form a color image with good color reproducibility without depending on a certain finish.

Next, the determination of the exposure amount in the present invention will be described. In the color image forming method of the present invention, since the Bizecky index is 10 or less and the influence of the light source fluctuation (color temperature, light source type) on the photographed image is very small, the photographed screen of the photographed material was measured, and the measured image was measured. By determining the exposure without collection based on the density, a color image can be obtained with a high pass rate.

Further, since a reference image (patch) 12b as shown in FIG. 2 is printed by the reference exposure device in the camera at the time of manufacturing or photographing, the difference in the production lot characteristic, the film by measuring the image It is possible to obtain a gray object that is affected by fluctuations in development performance, fluctuations in film characteristics due to aging until film development, and the like in the same manner as a photographed image. By obtaining the color filter density based on the standard image density (red, green, blue density) outside the shooting screen, the color reproducibility shift due to the heat and humidity of the photosensitive material due to aging, and the color reproducibility due to development fluctuation The deviation can be automatically corrected. Here, the exposure amount can be obtained based on the photographing screen density.

As described above, when the image of the reference color at the time of manufacture is printed, the above-mentioned image after development represents the reference color indicated by the characteristics of the film including the film development and the time until development.

By reproducing the reference image faithfully as the reference color on the color print material or on the display, proper color adjustment becomes very simple, and the color adjustment can be automated. With proper color adjustment, the obtained color image is always vivid and faithfully reproduced. In particular, with this method, a color image can be obtained with a pass rate of 100% in color reproduction, and a completely unattended system can be achieved. It should be noted that it is not necessary to print the reference image 12b when there is little variation in performance of the film or change in performance.

The above variation is a value corresponding to the density difference between the reference image (patch) 12b of the film to be printed and the reference image (patch) preset in the printer, and the color balance value F _J (described later It can be corrected by modifying F _J ). The reference image density that has been set may be stored in a memory by measuring the value or a reference film supplied when setting printer conditions. This reference image density may be a common value for each film. Therefore, it may be baked on the top or the last of the film.

Alternatively, the standard film density D
_JN(D in equation (4) below_JN) Is the darkness of the reference image 12b.
Use degrees. In this case, the reference image 12b is gray or a large number of frames
With an average color density of. For example, a gray image will turn gray
Color balance value F _JMust be set
The reference image of the film to be printed by

You. As a result, the base of the film to be printed is
The quasi-image 12b is printed in gray. In this case, the reference image
Image 12b also has a color density equivalent to the gray subject in the captured image.
Therefore, the captured image is also properly printed.

As yet another method, another exposure amount determining method based on the measured value of the reference image 12b is disclosed in JP-A-61-198144,
The method disclosed in Japanese Patent No. 61-223731 can be applied.

The gray (positive image) reference image 12b according to the present invention is used as a reference for selecting a measurement point used for exposure control.
By this method, the gray color can be easily and accurately determined, the complicated mechanism and operation unlike the conventional printers are not required, and the color balance of the obtained print is good. The above describes the method of the present invention for favorably determining the color balance of a color film.

Next, a more preferred embodiment of the present invention in the method for controlling the print density in the present invention will be described. The control of the darkness is insufficient only by the printing exposure control by the reference image 12b. This is because the subject, especially the main subject, that has been moved due to the intensity of illumination light on the subject and the exposure conditions of the camera does not have a constant density.

However, in a camera having a highly accurate exposure mechanism, the exposure to the main subject is constant, and therefore the face density of the main subject, for example, a person is constant. In this case, a predetermined print density can be obtained by giving a constant printing exposure amount. Such a method is effective in a camera in which an autofocus mechanism is combined to always determine the exposure amount for the main object part.

In many ordinary cameras, the exposure amount is not properly determined for the main subject. For this reason, the main subject density (for example, skin density) in the film image greatly varies. Most of the main subjects (about 80%) are people. By extracting the skin and face of a person and determining the printing exposure amount, it is possible to print an image including a person with high quality and high yield. Conventionally, the face and skin cannot be accurately extracted from the film image due to the film, illumination light, and other factors of variation. Since the film of the present invention has the reference image 12b and has little light source dependence, the skin color can be extracted with higher accuracy than before. Fluctuations in film characteristics, which have been the cause of erroneous recognition, can be prevented from the measurement of the reference image 12b. Further, since the light source dependency is small, it is possible to largely prevent misidentification due to a different light source other than daylight or a change in light source color temperature such as morning and evening or cloudy weather.

As an example of a method of determining an exposure amount using such a skin color, Japanese Patent Application Laid-Open Nos. 52-156624, 52-156625, and 53
-The 145620 publication etc. are known. A subject other than the skin has a wide print quality allowable range, and by extracting only an image having no skin color and determining the exposure amount so that the entire screen can be printed properly, a higher pass rate can be obtained.
By such a method of the present invention, a print pass rate close to 100% can be achieved.

The photometric unit applicable to the present invention may be a stationary scanner with an area sensor such as a CCD, a line sensor for scanning while driving the film, a scanner with a rotating disc having holes, a flying spot scanner or a laser scanner. Good.

The reference image may be read by a dedicated reading device other than the picked-up image. When the reference image is printed on the top or last of the film, no special reading device is required, and it is sufficient to control not to print only that image frame. If there is a reference image corresponding to each frame, the static scanner can use a film carrier as shown in FIG. 6 to simultaneously measure other than the photographed image portion, and calculate the photometric value separately for each area. You can do it. Such a film is convenient when a piece film cut into four or six frames or a plurality of film frames such as reorders and large stretches are selected and printed.

In order to make the effect of the present invention more certain, it is preferable that the photosensitive material used here has less variation in the steps other than the color printing step.

It is preferable that the automatic processing printing apparatus used here judges in advance whether the loaded film can be developed without problems, and if there is a problem, it can be returned to the state before the loading and returned to the customer. It is preferable that the automatic processing printer used here has a short time until a print is completed after one film is loaded,
It is preferable that the next print comes out without delay even when continuously input. It is preferable that the automatic processing printing apparatus used here rubs the surface of the photosensitive material during handling and does not cause scratches. For that purpose, it is preferable to process and print the film without moving it.

EXAMPLES In a color image forming method according to the present invention,
A method of recording a standard gray image on a part or all of the outside of the photographing screen of the color photographing material and reproducing the photographed image on which the gray image is recorded on the display will be specifically described as an example. The method of reproducing the captured image on the display is not limited to this embodiment.

FIG. 1 shows a display device for displaying the color negative film of the present invention. White light source 11
The illumination light emitted from 0 is sufficiently diffused by the diffusion cylinder 111, and then the color negative film 12 of the present invention is illuminated from behind. The color negative film 12 is composed of a photographed image 12a and a reference image 12b, and the color negative image shown in FIG. 1 is picked up by a color TV camera 113, and a red video signal R, a green video signal G, and a blue video signal are taken. Converted to signal B. These video signals are converted to γ by the γ correction circuit 114.
After being corrected, it is converted into a positive image by the negative / positive conversion circuit 115 and sent to the amplification circuit 116. This amplifier circuit 116
, The amplification factor is adjusted based on the film image density calculated by the CPU 26. The video signals amplified for each color by the amplifier circuit 116 are added to the memory color signals by the adders 117 to 119 and then sent to the driver 120. This driver
The drive unit 120 drives the color CRT 121 to display a composite image in which a positive image is fitted in a memory color frame or a composite image in which a memory color is arranged near the positive image on the display surface of the CRT 121.

The system bus 125 has a CPU 126 and a ROM.
127, RAM128, I / O port 129, and CRT controller 130 are connected. A keyboard 131 is connected to the I / O port 129.
The 131 is provided with keys for inputting various operation commands. Further, an amplification circuit 116 is connected to the I / O port 129, and the amplification factor of each color is adjusted according to the printing exposure amount calculated by the CPU 126.

Red video RAM 137a, green video R
The AM 137b and the blue video RAM 137c store memory color data of color components forming, for example, gray. In this memory color data, 8 bits are applied to one pixel, whereby 256-step gradation can be expressed for each color.

The CRT controller 130 has a color T
An address signal is created from the sync signal from the V camera 113 and sent to the video RAMs 137a-137c. The memory color data is sent to the shift registers 141a to 141c provided for each color. Each of the shift registers 141a to 141c has eight output terminals, and frame data to be placed on a plurality of scanning lines is written therein. The frame data of each color is output in parallel with 8 bits forming one pixel, sent to the D / A converters 142a to 142c provided for each color, and converted into analog signals. The analog signals of the respective colors are sent to the adders 117 to 119 described above, respectively, and are added to the video signals of the respective colors to perform image synthesis.

Next, the operation of the above embodiment will be described. First, the CPU 126 reads the standard size and memory color data from the ROM 127, and uses this to read each video RAM 13
Write to 7a-137c. On the other hand, the color TV camera 113
A color negative image 12 illuminated with white light is captured and video signals of each color are generated. This video signal is subjected to .gamma. Correction, negative / positive conversion, and brightness adjustment processing according to the printing exposure amount, and then sent to the driver 120 via the addition circuits 117-119. The driver 120 drives the color CRT 121 to display a positive color negative image on the CRT 121.

The CRT controller 130 creates an address signal from the synchronizing signal of the color TV camera 113, reads gray data stored in the memory color video RAMs 137a to 137c with this address signal, and shifts it to the shift register 14
Send to 1a to 141c. The shift registers 141a to 141c have eight
Bit signals are read in parallel and this is read by the D / A converter 14
Send to 2a-142c. The analog-converted frame signal is sent to adders 117 to 119 to be subjected to image synthesis.

As shown in FIG. 3, the color CRT 121 displays a positive image in which the reference image is simultaneously fitted in parallel with the memory color gray. By observing this positive image, it is compared and examined whether the color of the memory, for example, a gray image 145, and the color of the reference image (gray) 146 of the displayed film match. If they do not match, the keyboard 131 is operated to input so that the color densities of the two images match. When this correction data is input, the CPU 126 calculates the amplification factor of the amplification circuit 116 for each color according to the correction data and sends it to the amplification circuit 116. The amplifier circuit 116 amplifies the video signal of each color with a new amplification factor, so that the color and brightness of the color negative image displayed on the color CRT 121 changes. In this way, the color negative display reference image 146 is made to match the color density of the memory color 145.
The positive image (display image) of the captured image is properly displayed due to the match between the two images. The memory color 145 may be displayed so as to surround the display image, or may be displayed on the outside of the display image or a part of the inside of the display image, preferably in contact with the display reference image 146 in a small area capable of color evaluation. .

When the reference image 12b is not burned adjacent to the photographed image 12a of each frame, the reference image 12b is picked up and its image signal is A / D converted, and the data is converted to another video R.
The memory is stored in AM (not displayed). When the captured image 12a is displayed, the data may be read from the video RAM (not displayed), D / A converted, combined with the memory color 145, and the reference image 146 displayed at a predetermined location.

A video RAM which also forms the memory color 145
The amplification factor of the amplifier circuit 116 may be automatically adjusted so that the data and the captured video signal of the reference image 12b on the film match. In this case, it is not always necessary to display the memory color 145 and the reference image 146 on the display. The memory color 145 and the reference image 146 may be displayed on the display, and after automatic adjustment, the keyboard 131 may be operated to match the color or density preference. Also, memory color 145
If is not displayed, the memory color data may be stored in the ROM 127 instead of the video RAMs 137a to 137c.

When the color densities of the memory color 145 and the reference image 146 are matched on the display, the color densities of the memory color 145 and the reference image 12b on the film are determined in advance so that the display image is properly displayed. I need to put it. The colors of the memory color 145 and the reference image 146 may be any colors as long as they are constant, but a color in which the difference can be visually recognized well, that is, gray or flesh color is preferable.

The display image itself can be used for viewing a color film, and it is not necessary to adjust the display image for each film frame. Also, a film frame can be selected at the time of printing and a composition for trimming can be determined. Furthermore, it can be effectively used for determining the exposure amount in a photographic printing apparatus for negative films.

As a reference example, a method of recording a reference image on a part or all of the outside of the photographing screen of the color photographing material and printing the reference image on the color print material will be specifically described.

When the light receiver 52 is a scanner, , Red, green, and blue densities (or values proportional to the densities) are calculated for each point of the reference image 12b and the captured image 12a, and the average densities of red, green, and blue are respectively calculated by arithmetically averaging these. To do. The obtained average density D _JN of the reference image 12b is stored in the memory 63, and the red, green, and blue average density D _{J of} the captured image 12a is also stored in the memory unit 63.

The keyboard 30 is provided with an alphabetic character key for inputting standard exposure condition data and a print key for starting printing. The calculation unit 87 uses the data stored in each storage unit described above to calculate the exposure amount for each color from the following equation.

A lamp 20 is provided to illuminate these negative films, and the light emitted from the lamp 20 is a cyan filter 21, a magenta filter 22, and a yellow filter.
At 23, the three-color light components are adjusted. The baking light whose light quality is adjusted by the color filters 21 to 23 is sufficiently mixed in the diffusion box 24, and then the negative film is illuminated from below. The light transmitted through the color negative film 19 is printed by the printing lens 25 and the shutter.
The exposure position is reached after 26.

On the right side of the exposure position, a cutter 32 for cutting the exposed color paper 19 into a predetermined length or more when desired and a pair of rollers 33 are arranged. The roller pair 33 feeds the exposed color paper 19 to the stock chamber 34 in which it is stocked. This stock room has a roller pair
35 and 36 are arranged to form two loops. On the right side of the stock chamber 34, a photographic development processing section 37 is formed. The photographic development processing section 37 is composed of a color developing tank 38, a bleach-fixing tank 39, and three water washing tanks 40 to 42. A series of color papers 19 are transported at a constant speed by a large number of transport rollers and sequentially dipped in the respective processing tanks, whereby color development, bleach-fixing and water washing are performed. A drying drum 46 and a cutter 47 are arranged on the right side of the photo developing processing unit 37. After the color paper 19 which has been photo developed is dried, the color paper 19 is separated by the cutter 47 into individual frames and a sorter (see FIG. (Not shown) etc.

FIG. 5 shows a control system. The negative carrier 18 is composed of a plate 50 and a mask 51, and holds the color negative film 12 between them during printing. In order to measure the three color densities of the color negative film 12, a light receiver 52 is provided, and an image is read immediately before printing a photograph, and the photographed image 12a and the reference image are read.
The 12b three-color signal is output as a time series signal. The light receiver 52 includes a red sensor 53, a green sensor 54, and a blue sensor 55.

The input signal of the photodetector 52 is an A / D converter.
After being converted into digital signals at 56, they are sent to a logarithmic converter 57. This logarithmic converter 57 converts the input signal into an approximate concentration signal by logarithmically converting it. The data converted into the density signal is sent to the computer 60. This computer 60 has an I / O port 61, a CPU 6
2. It comprises a memory 63 and controls the filter adjusting section 67 and the shutter driving section 68, etc., in addition to taking in density data and calculating the exposure amount.

An example of the calculation of the exposure amount is shown below. log E _JI = C _J · S _J (D _JI −D _JN ) + F _J + d _JI (4) where, E _JI : exposure amount F _J : color balance value, for printing the reference film at a predetermined color density It is a constant and is determined by the color paper and automatic color photoprinting device. D _JI : Exposure correction amount based on the image content D _JN : Reference film density D _JI : i film frame exposure control C _J : Color correction coefficient J: R, One of G and B I: Film frame S _J : Slope control coefficient (= 0.5 to 2.0) D _JI −D _JN Under slope control coefficient D _JI −D _JN ≧ 0 Over slope Control coefficient

II. Photographing and Printing [II-1] Using the samples 101 to 109, using a standard white light source as a standard light source, a mannequin doll placed in front of a wallpaper having the same reflection spectrum as white of Macbeth Color Checker After taking an image with proper exposure for 1/50 second and performing the developing treatment shown in Table 1, a color filter was selected for each film so that the print was closest to the original.
Here, Fuji Color Super FA Paper (manufactured by Fuji Photo Film Co., Ltd.) was used as the printing material. Under these conditions, Samples 101 to 109 are shown in Table 3 under respective shooting conditions (4
4 × 2 = 32 conditions) were photographed, the same filters as those selected for each of the above films were used, and only the printing time was changed for printing, and each evaluation was performed. Here, the color correction coefficient C _j is 0.0. The results are shown in Table 4.

[0153]

[Table 3]

[0154]

[Table 4]

The pass rate shown in Table 4 is based on the visual judgment of 10 amateur panelists regarding photographs. "Failure" refers to the level at which an amateur photographer does not endure observation and requests DPE acceptance for reprinting. Therefore, a pass rate of 100% means that amateur photographers can take snapshots of people and receive all prints. From Table 4, it was revealed that the comparative example had a poor pass rate as compared with the reference example, the print was unacceptable with any light source, and it was impossible to make a completely unmanned system.

On the other hand, according to the reference example, if a color filter is optimally selected, a film taken under any light source can be printed under the same filter condition, and an unmanned printer can be manufactured. From the above, the effect of the reference example is clear.

[II-2] Using Samples 101 to 109, each subject (4 conditions) shown in Condition 2 of Table 3 was photographed with each illumination light (4 conditions) shown in Condition 1 of Table 3, and outside the screen. After exposure to the green light-sensitive layer with a fog density of +0.5 using the C light source, and performing the development process shown in Table 1, the color was changed so that the exposed area outside the screen became gray for each film. A filter was selected, and then each screen was printed by changing only the exposure illuminance and evaluated in the same manner as above. The results are shown in Table 5.

[0158]

[Table 5]

From Table 5, it was revealed that the comparative examples other than the reference example gave unacceptable prints with any light source, and it was impossible to make a completely unattended system.
On the other hand, in the film of the reference example, if the color filter is selected so that the exposed part outside the screen becomes gray, the film taken under any light source can be printed under the same filter condition, and it is possible to make an unmanned printer. . From the above, the effect of the reference example is clear.

[II-3] Samples 101 to 1 as in [II-2]
Using 09, each illumination light (4 conditions) shown in condition 1 of table 3
Each of the subjects (4 conditions) shown in Condition 2 is photographed, and the film exposed to the outside of the screen by the C light source so that the development density of the green-sensitive layer becomes fog +0.5 is stored under the following storage conditions a to f. Below, 6 each were produced. These films were printed according to the following printing conditions.

(Storage Conditions) a: Repeating [II-2] (corresponding to almost ideal storage and development of the film) b: Storage of the film after photography in an environment of 50 ° C. and 80% for 1 week Develop, same as a below c; Film after shooting is stored in 50 ° C 20% environment for 1 week, developed, same as a below d: Film before shooting is stored in 50 ° C 80% environment for 1 week, and then taken Same as a below; same as a except that the developing temperature was lowered by 3 ° C f; same as a except that the developing temperature was raised by 3 ° C

(Printing conditions) Method 1; All of a to f are printed with the same filter as a. Method 2; Each of a to f is selected by a color filter so that an exposed portion outside the screen becomes gray. The obtained results are shown in Table 6.

[0163]

[Table 6]

From Table 6, it can be seen that, according to the reference example, when both the saturation reproduction index and the Bizeckey index are satisfied, the pass rate of the obtained print is surely increased (method 1). Further, by applying the method of printing the image portion by selecting a color filter for printing the exposed portion outside the screen in gray from Method 2, the performance changes before or after the film is photographed, or the developing condition changes. Then, it was found that a print with a pass rate of 100% can be obtained even when the photographic performance changes, and the effect of the reference example is clear. In particular, an unmanned printer can be achieved with a pass rate of 100%.

By the same principle, the reproduced image to be observed is CR.
Even with a display such as T, it is apparent that satisfactory color reproduction can be achieved by reproducing the photographic material in the range of the reference example so that the exposed portion outside the screen becomes gray.

Reference Example 2 Each film obtained under the same conditions a to f as developed as in Reference Example 1 was automatically printed by the method described below.

Method I: Automatic color printer FAP3500
(FUJI FILM) for high-correction printing method II; automatic color printer (same as above) for low-ward correction printing method III; for each of the films obtained in a to f, the exposed area outside the screen becomes gray. Table 7 shows the above results.

[0168]

[Table 7]

In the method I, the frames of the person placed in front of the white wallpaper were acceptable under the conditions a to f, but the images of the persons placed in front of the blue, green and red wallpapers were Faces finished in yellow, magenta and cyan colors respectively
A pass rate of 0% was impossible. In Method II, the variation in color reproduction between the films under each of the conditions a to f is still large, but according to the present invention, the increase in the pass rate is clear. Method
In III, all the frames were acceptable under each of the conditions a to f, and the pass rate was 100%.

From the above, it is shown that good results can be obtained according to the reference example, and in particular, according to Method III, a print with a pass rate of 100% can be obtained, and the achievement of a completely unattended system. Is also possible.

Example 1 The film obtained under the same developing conditions as a to f as in Reference Example 1 was used as a champion 23VE (Fuji Film).
V-Accs of Mini Lab Printer Processor Co., Ltd.
Displayed on the monitor. The memory color data was set so that the outer peripheral portion became the standard gray. After the gray image created outside the film screen was displayed on the V-Accs monitor and the color was adjusted by the operation unit so that it became the same color as the outer peripheral portion of the display image on the monitor, the film image was displayed under that condition. As a result, it was confirmed that all the film images of the present invention can be displayed with an appropriate color density. In the comparative example, a photograph of a fluorescent lamp or the like resulted in insufficient results, and the effect of the present invention was clear.

[0172]

According to the present invention, the color reproducibility deviation due to the difference in the light source, the color reproducibility deviation due to the color ferria, etc. are better corrected comprehensively to further improve the pass rate of the obtained color image. be able to. Further, according to the present invention, by using the method of recording the reference image especially outside the photographing screen, the pass rate of the obtained color image can be reproduced at 100%, and a completely unmanned system can be achieved.

Further, according to the present invention, it is possible to obtain an image forming apparatus for forming a color image having a constant finish and good color reproduction without requiring human color adjustment.
