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 reproducing a color image vividly and faithfully on a display. Further, the present invention relates to an image forming apparatus (display apparatus) which does not require color adjustment by a human and can always obtain 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. Above all, a well-known method of adjusting the color balance in a color print developed based on the principle of Evans' research that the color of the entire screen becomes gray when the colors of the entire screen are mixed is well known.

The problem of color balance has been largely solved by the Evans method, but is still insufficient. In this method, a standard negative is used, and color correction is performed for the density difference between the negative density to be printed and the standard negative (for example, an exposure determination formula in Japanese Patent Application Laid-Open No. 64-77041 can be used). However, this method is characterized by a high statistically acceptable rate for various subjects.For example, if there is a vivid primary color in a part of the screen, the entire screen is affected by the color. The color may be slightly dyed with the complementary color of the primary color, thereby deteriorating the quality of the image. For example, the face of a person wearing red clothes may be finished in cyan, or the road may become magenta when photographing a green fence (color feria by color correction). This tendency can be achieved, for example, by masking or DIR to enable more vivid color reproduction.
It becomes remarkable as the layering effect by the coupler is increased.

In addition, differences in color temperature of the light source at the time of photographing, differences in photographing light quality such as photographing under a light source having an improper energy distribution such as a fluorescent lamp and a mercury lamp, aging due to heat and humidity of the photosensitive material, development conditions It is known that a shift in color reproducibility is caused by fluctuations in color reproduction. However, such a shift in color reproducibility cannot be sufficiently solved only by applying the statistical principle as described above.

[0005] Therefore, in order to prevent these, a so-called verification work is performed in which a human observes a film screen in advance to predict whether color feria has occurred and corrects in advance. There is a difference in technology, causing problems such as a change in color upon reprinting. That is,
Even if you shoot the same scene, the color tone will differ depending on the color developing station that develops, or if you print the color negative film that has been developed and printed once again to the same color developing station, you will not be able to obtain the same color print. The problem of color reproducibility, which is most important in image quality, has not yet been solved. This is because there is no guarantee that the technology developed will be obtained on-site, i.e., with the print finish normally obtained in a color lab. In other words, the effect of the technology can be obtained if humans pay close attention and repeat the color adjustment many times to the best finish, but the effect may not be obtained with the automatic color printer of unmanned driving is there. Many devices and methods have been developed to automatically perform human verification using a machine, but they have not been sufficiently satisfactory.

Before the Evans method was adopted, in order to adjust color balance in color printing, a fixed standard patch was printed on the last part of the negative film before development processing, and each density was measured. In some cases, a method of compensating for fluctuations in film speed and film sensitivity balance has been adopted. However, this method does not include the quality of photographing light, and performing only such a correction is ineffective and has a problem. On the other hand, a method has been proposed in which an illumination light source is projected between photographed frames by a camera and the portion is printed in a fixed color (for example, Japanese Patent Laid-Open No. 52-133).
No. 33). However, the reflected light is not illumination light, but reflected light of the subject, and the reflected light is light obtained by multiplying the spectral reflectance of the subject by the illumination light, and it is inevitable to make erroneous correction.

Further, in recent years, a method has been disclosed in which the exposure amount is determined based on an image portion or a photometry point of a specific color in a film image (for example, JP-A-52-156624, JP-A-53-1233).
No. 0, JP-B-56-15492, JP-B-59-29847, JP-A-59-29847
220780, JP-A-61-198144, etc.). In these methods, many ideas and complicated methods are employed to find a specific color, for example, a gray subject in a film image. However, in an image in which the photographing light quality and film characteristics differ from those of daylight, the color of the subject or the light source cannot be distinguished, and it is difficult to find a gray portion from the image. I have a problem that I cannot get a print.

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 JP-A-62-298291 and JP-A-63-48541. However, these methods are manually adjusted by trial and error, or are adjusted in color according to the amount of exposure of the negative film, and have the same problems as described above.

Further, there is a method of minimizing the color correction by the above-mentioned Evans method in order to eliminate the color fear. In this case, however, the color of the photograph is greatly changed due to the difference in light quality at the time of photographing as described above. Can not be prevented, likewise the secular change due to heat and humidity of the photosensitive material,
It is not possible to prevent the color from going out of order due to fluctuations in the development conditions.

On the other hand, in a color light-sensitive material, in order to increase the fidelity of saturation and hue, a method of newly providing a donor layer having a multilayer effect which approximately achieves a negative portion of a color matching function (Japanese Patent Laid-Open No. 61-1986) No. 34541), a method of approximating the negative part of the color matching function by the donor layer of the multilayer effect, and bringing the spectral sensitivity distribution close to the positive part of the color matching function (Japanese Patent Application Laid-Open No. 62-16448) is known. In addition, the spectral sensitivity of the blue, green, and red-sensitive silver halide emulsion layers is provided in order to provide a photographic light-sensitive material whose color reproducibility is faithful and color reproducibility does not significantly change under photographing conditions with various light sources. A method of limiting the distribution to a certain range by selecting and combining a spectral sensitizing dye and a filter dye (US Pat.
672,898), with the aim of providing a color photographic material having a small change in color reproducibility due to a change in the color temperature of a light source at the time of shooting and having high chroma color reproducibility, the spectral analysis of blue, green, and red-sensitive silver halide emulsion layers. A method in which the width of the maximum sensitivity of the distribution is defined and a diffusible DIR compound is contained (Japanese Patent Application Laid-Open No. 59-131937)
), With the aim of providing a color photographic light-sensitive material in which the color reproducibility due to the change in the color temperature of the light source at the time of photographing is small, and the primary colors and intermediate colors are reproduced faithfully, the spectral sensitivity distribution of each emulsion layer and A method of defining the magnitude of the interlayer effect (Japanese Patent Application Laid-Open No. Sho 64-19346) is known.

[0011]

However, a pass rate which can be sufficiently satisfied even when a normal photographic printing operation is performed using a known color photographic light-sensitive material which is said to have little color reproducibility and / or light source dependence. Could not obtain a color print.

Therefore, the color reproducibility shifts due to the difference in the light source, the color reproducibility shifts 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 fluctuation. It is desired to develop a color image forming method capable of correcting the shift and the like better overall and improving the pass rate of the obtained color image.

In particular, no system has yet been developed which is capable of correcting these color reproducibility deviations unattended and reproducing with a pass rate of almost 100%. To achieve a completely unmanned system, the question of whether this pass rate is 100 percent or not is very important.

[0014] In recent years, color processing is being carried out at a photographic material store with a small apparatus called a mini-lab, and the number of cases is increasing. However, even if there is a dedicated worker, color balance adjustment requires a high level of experience and skill. Therefore, the pass rate has not reached 100%. Over-the-counter processing has the advantage that customers can receive color prints quickly, but in addition to the problem of inadequate pass rates, productivity per employee is lower compared to large-scale processing performed in large color development laboratories However, there is a problem that the cost of color printing increases. If a method was developed that could achieve 100% pass rate color prints unattended, labor costs would be eliminated and the cost of color prints would be reduced, so this effect would be immeasurable. Therefore, there is a further need for a color image forming method capable of achieving a completely unmanned system in which the pass rate of the obtained color image can be reproduced at 100%.

[0015] The same problem as described above also exists in the formation of a color image directly displayed on a CRT from a color negative film. Therefore, the present invention always forms a color image with good color reproduction with a fixed finish even in such a color image formation. It is to provide a way to do it.

A further object of the present invention is to form a color image with good color reproducibility at a constant finish without the need for human color adjustment in the formation of a color image directly displayed on a CRT from the color negative film. To provide an image forming apparatus.

[0017]

Means for Solving the Problems These problems are described in (1)
Saturation reproduction of the color reproduction in a color image forming method of photographing and developing using a color photographing material having a red-sensitive, green-sensitive, and blue-sensitive silver halide emulsion layer on a support and reproducing it on a color display The index is 70% or higher, the Bizecki index is 10 or lower, and some or all of the off-screen material is almost the same as before or after shooting.
A color image forming method characterized in that a standard gray image recorded at the time is recorded, a condition is selected on the display such that the recorded image becomes gray, and a photographed image is reproduced on the display under these conditions. .

(2) A standard photographic material having a red-sensitive, green-sensitive and blue-sensitive silver halide emulsion layer on a support, which is recorded on a part or all of the outside of the photographic screen of a color photographic material before or almost simultaneously with the photographing A display device characterized by selecting a condition under which a gray image becomes gray, and reproducing a photographed image on the display under this condition. It is solved by.

That is, according to 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 by forming a color image with no color correction, the above-described shift in color reproducibility, in particular, shift in color reproducibility due to a difference in light source and shift in color reproducibility due to color feria can be eliminated. In other words, it can be seen that setting the above-described color image forming system enables a color print having a sufficiently satisfactory color reproducibility to be obtained at a high pass rate even when photographing various kinds of light sources and / or various kinds of subjects. It was issued.

The saturation reproduction index is preferably at least 75%, particularly preferably at least 80%, and the Bizecky index is preferably at most 8, particularly preferably at most 5. Blue if the saturation reproduction index is 70% or less,
Not only does the color reproduction of primary colors such as green and red deteriorate, but also the reproduction of skin color, which is the most important color for color photography, becomes extremely poor, deteriorating the image quality.

When the Bizecki index exceeds 10, the type of illumination light source, in particular, HID lamps such as various fluorescent lamps, metal halide lamps, high-pressure sodium lamps, high-pressure mercury lamps, etc., which have been developed in response to diversifying needs in recent years, are used. The fidelity of color reproduction when photographing a subject is significantly impaired. Further, even in sunlight, the influence of the color temperature due to the sunshine, shade, photographing time, etc. becomes remarkable.

The term "saturation reproduction index" used here means that 18 colors of the Macbeth color chart are photographed with a standard white light source and appropriate exposure, and then reproduced on the print material according to the standard processing specified for the print material, and reproduced with the original. Is reproduced on the a * b * plane, and the ratio of the reproduced area surrounded by 18 colors to the original area is displayed as a percentage.
The closer this value is to 100%, the better the saturation reproduction.

The Bizecky index referred to here is JISZ87
Photographed a neutral color object having the spectral energy distribution of 12 metasomers of Bizecki shown in 19, printed the 12 colors with the gray color as the center, and reproduced the 12 colors on the a * b * plane. Reproduce and represent the standard deviation of 12 colors.

[0024]

(Equation 1)

The two indices when a color image is formed on a display are similarly defined based on the colors reproduced on the display.

When the color image forming system is set so that the chroma reproduction index and the Bizecki index defined above satisfy both of the above values, the reason why the sunlight, fluorescent lamp, mercury lamp, incandescent lamp,
It is not always clear whether photographs taken with various illuminations such as strobe light can be obtained with excellent color reproducibility and a high pass rate. However, in the present invention, the value of the color correction coefficient _Cj in the color image forming system is reduced to about 0.8 in the related art because the light source dependence is small.
The value can be reduced from 1.0 to 0.0 to 0.5, and thereby the occurrence of color feria can be completely eliminated.

A method for satisfying both the value of the saturation reproduction index and the value of the Bizecki index has been intensively studied. It has been found that a method that satisfies both conditions cannot be obtained unless at least two or more of the following techniques 1) to 3) are combined.

1) A technique for defining the spectral sensitivity distribution of each photosensitive layer of a color photographic light-sensitive material and the magnitude of the interlayer suppression effect between the respective photosensitive layers in 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)

[0030] a is, and the magnitude of the interlayer _{effect, -0.15 ≦ D B / D R} ≦ + 0.20 -0.70 ≦ D G / D R ≦ 0.00 -0.50 ≦ D B / D _G ≦ 0.000−0.10 ≦ 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 a blue-sensitive layer from the red-sensitive layer, D _G / D _R
Green-sensitive layer from the red-sensitive layer, D _B / D _G is a blue-sensitive layer from the green-sensitive layer, D _R / D _G is the red-sensitive layer from the green-sensitive layer, D _G / D _B is green-sensitive layer from the blue-sensitive layer , D _R / D _B is the representative of the respective sizes of the interlayer effect on the red-sensitive layer) from the blue-sensitive layer.

The details are described in JP-A-64-19346. The interlayer effect here is obtained as follows. For example, the interlayer effect (D _R / D _G ) from the green-sensitive layer to the red-sensitive layer is obtained by first providing stepwise exposure with green light (Fuji Filter: BPN-55) and then red light (Fuji Filter: SC). In the characteristic curve obtained by uniformly exposing at (−60), the fog density and the magenta density difference (Δy) between the density at the exposure Q which is 1.5 times larger than the exposure P at which the exposure is given by logE are given. 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 It is a measure of the degree. 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 interlayer suppression effect is effective, and the interlayer suppression effect is represented by a negative value. When Δx is a positive value, the interlayer suppression effect is not effective (has become cloudy), and the magnitude is represented by a positive value. Here, the spectral sensitivity distribution of the blue-sensitive layer, the green-sensitive layer, and the red-sensitive layer can be obtained, for example, by appropriately combining spectral sensitizing dyes having the structural formulas shown below.

In order to achieve the interlayer effect, it is effective to include the diffusible DIR compound in only one of the blue-sensitive layer, the green-sensitive layer, and the red-sensitive layer, but it is necessary to obtain better color reproduction. It is preferable to contain it in 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.

A certain color-sensitive layer may be divided into two or more layers, and one or more of the layers may contain a diffusible DIR compound, and the remaining layers may not. 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 suppression effect, a method of appropriately changing the iodine content of the emulsion or adding a colored coupler to mask unnecessary absorption of a coloring dye may be used. A method of intentionally mixing a coloring dye different from the color sensitivity to increase the color turbidity and offset the interlayer suppression effect may be used.

The compound capable of releasing a diffusible development inhibitor or a precursor of a diffusible development inhibitor upon coupling with a color developing agent used herein is represented by the following formula (I). It is described in.

Or Y, Y represents a group capable of binding to the coupling position of the coupler component J and leaving by the reaction with the oxidized color developing agent, and a development inhibitor having a high diffusibility or a compound capable of releasing the development inhibitor. )

2) In a color photographic light-sensitive material, a donor layer having a multilayer effect which approximately achieves the negative portion of the color matching function is newly provided, and more preferably, both the spectral sensitivity distribution and the positive portion of the color matching function are made closer. Technology, 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 has a wavelength in the range of 500 nm to 600 nm. centroid wavelength of size distribution of the interlayer effect receiving from the layer of (lambda _-R) and 500nm <λ _-R ≦ 560nm, and λ _G -λ _{- R} ≧ 5nm
And more preferably, the distribution S of the magnitude of the multilayer effect.

It is assumed that For details, see JP-A-61-3454.
No. 1 and No. 62-160448.

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 multilayer effect received from another layer in the range of nm to 600 nm can be obtained as follows.

(1) First, a red filter that transmits a specific wavelength or more or an interference filter that transmits only a specific wavelength so that a red-sensitive layer that emits cyan at a wavelength of 600 nm or more is exposed and other layers are not exposed. Is applied to uniformly expose the red-sensitive layer that develops cyan to an appropriate value. (2) Next, when a spectral exposure is applied, the blue-sensitive layer and the green-sensitive layer act on the fogged emulsion by a layering effect of development suppression to give an inverted image. (3) From this inverted image, a spectral sensitivity distribution S _-R (λ) as an inverted photosensitive material is obtained. (4) Calculate the center-of-gravity wavelength (λ- _R ) of the multilayer effect by the following equation.

[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. In the same manner, an appropriate interference filter is selected, and a blue-sensitive layer and a green-sensitive layer are previously covered with the light to give an energy spectrum light, so that S _-B (λ) and S _-G (λ)
A distribution can be obtained.

In order to obtain these spectral sensitivity distributions, known techniques, for example, selection of an appropriate sensitizing dye, or a fixed dye such as a yellow filter, an ultraviolet absorbing filter, or an ultraviolet absorbing filter, or a diffusible dye may be used. Further, in order to correct the distortion of the spectral sensitivity distribution due to the light absorption of the upper layer, the spectral sensitivity distribution of a layer having the same color sensitivity (for example, a red sensitive layer) and a different sensitivity may be slightly changed. Masking couplers, DIR compounds,
What is necessary is just to select suitably the addition amount and addition layer of an adsorptive antifoggant. In addition, a layer structure which is easily affected by the layering effect, for example, a method of lowering the silver / coupler ratio or using a coupler having a low coloring property may be employed.

3) A coupler having a wide color reproduction range and low side absorption is used as color paper. For example, there is a pyrazoloazole type magenta coupler. Among these pyrazoloazole type couplers, imidazo [1,2-b] described in U.S. Pat. Pyrazoles are preferred,
The pyrazolo [1,5-
b] [1,2,4] triazole is particularly preferred. In addition, a pyrazolotriazole coupler in which a branched alkyl group is directly linked to the 2, 3 or 6-position of the pyrazolotriazole ring as described in JP-A-61-65245, as described in JP-A-61-65246 Pyrazoloazole couplers containing a sulfonamide group in the molecule, pyrazolotriazole couplers having an alkoxyphenylsulfonamide ballast group as described in JP-A-61-147254, and European Patent Publication No. 226,849, 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, cyan couplers having little side absorption may be used. Specifically, JP-A-63-264753 and JP-A-64-552 may be used.
Nos., No. 64-554, No. 64-555, No. 64-556, etc. can be used. Further, a short-wavelength yellow coupler can also 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 found that 1) to
With only one of the techniques of 3), the saturation reproduction index and the Bizecky index cannot both be set to values according to the present invention, and these are combined to form a spectral sensitivity distribution for satisfying the above condition. It was found that the direction and magnitude of the layering effect, the spectral sensitivity distribution of the donor layer, and the magnitude of the layering effect from the donor layer were obtained by precise experiments. In a color image forming system that satisfies both the saturation reproduction index and the Bizecky index, when one of the above conditions is operated, at least one of the two indices may not be satisfied immediately. Cannot be determined independently. However, those skilled in the art can easily set each condition in the above technology so as to satisfy both the above indices. If the two indices are set so as to satisfy the above values, for example, if the above techniques are appropriately combined to set a color photographing material and a color print material which satisfy the above indices, the photographing conditions can be adjusted without color correction. A color image with good color reproducibility can be formed with a fixed finish without depending on the image quality.

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 Bizecki index is 10 or less and the influence of the light source variation (color temperature, light source type) on the photographed image is very small, the photographed image of the photographed material is measured, and the measured image is measured. By determining the exposure with no correction 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 burned by a reference exposure device in the camera at the time of manufacturing or photographing, the image is measured to obtain a difference in manufacturing lot characteristics and film. It is possible to obtain a gray subject which is affected by fluctuations in the performance of development and changes in film characteristics due to aging until film development in the same manner as a photographed image. By calculating the color filter density based on the reference image density (red, green, and blue density) outside the shooting screen, the color reproducibility shift due to aging due to heat and humidity of the photosensitive material, and the color reproducibility due to development fluctuation The displacement can be automatically corrected. Here, the exposure amount can be obtained based on the photographing screen density.

As described above, if the image of the reference color is printed at the time of production, the image after development represents the reference color indicated by the characteristics of the film including the film development and the aging until the development.

By faithfully reproducing this reference image on a color print material or on a display as a reference color, proper color adjustment becomes very simple and color adjustment can be automated. With proper color adjustment, the obtained color image can always be reproduced vividly and faithfully. In particular, this method makes it possible to obtain a color image with a pass rate of 100% for color reproduction and to achieve a completely unmanned system. It should be noted that when the performance variation and performance change of the film are small, it is natural that the reference image 12b does not need to be burned.

[0054] The above variation is printed try to reference image (patch) 12b in advance the color balance value with the value corresponding to the density difference between the set printer criteria image (patch) F _J (described later of the film ( It can be corrected by correcting F _J ) in equation 4). The set reference image density may be stored in a memory by measuring a numerical value or a supplied reference film when setting printer conditions. The reference image density may be a common value for one film. Therefore, it may be burned into the top or last of the film.

As another method, the reference film density D
_JN(D in equation (4) below)_JN) Shows the darkness of the reference image 12b.
Use degrees. In this case, the reference image 12b is gray or many frames.

The quasi image 12b is printed in gray. In this case,
The image 12b has a color density corresponding to a gray object in the photographed image.
As a result, the photographed image is also appropriately printed.

As another method, another method for determining the exposure amount based on the measured value of the reference image 12b is disclosed in Japanese Patent Application Laid-Open No. 61-198144.
The method described in JP-A-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.
In this method, gray is easily and accurately determined, a complicated mechanism and operation are not required unlike a conventional printer, and the color balance of a print obtained is good. The above describes the method of the present invention for favorably determining the color balance of a color film.

Next, in the method of controlling print density in the present invention, a further preferred embodiment of the present invention will be described. The control of the density is not sufficient only by the printing exposure control based on the reference image 12b. This is because the density of the object shifted due to the intensity of illumination light on the object or the exposure condition of the camera, especially the main object, is not constant.

However, in a camera having a high-precision exposure mechanism, the exposure to the main subject is constant, and therefore, the density of the main subject, for example, the face of a person is constant. In this case, a predetermined print density can be obtained by giving a fixed printing exposure amount. Such a method is effective in a camera in which the exposure amount for the main subject pair is always determined by combining the autofocus mechanism.

In many general 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 varies greatly. Many of the main subjects (about 80%) are people. By extracting the skin and face of a person and determining the amount of exposure for printing, an image including the person can be printed with high quality and high yield. Conventionally, a face or skin cannot be accurately extracted from a film image due to film, illumination light, and other factors of variation. Since the film of the present invention has the reference image 12b and has little dependence on the light source, it is possible to extract the flesh color with higher precision than before. Fluctuations in film characteristics, which have conventionally been the cause of misperception, can be prevented from measuring the reference image 12b. In addition, since the light source dependence is small, it is possible to largely prevent misunderstanding in different light sources other than daylight and in light source color temperature changes such as morning and evening and cloudy weather.

Examples of the method of determining the exposure amount using such flesh color are disclosed in JP-A-52-156624, JP-A-52-156625, and JP-A-52-156625.
-No. 145620 is known. For subjects other than the skin, the print quality has a wide allowable range, and only a non-skin-colored image is extracted to determine an exposure amount such that the entire screen can be properly printed, so that a higher pass rate can be obtained.
With such a method of the present invention, a print acceptance rate close to 100% can be achieved.

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

The reading of the reference image may be performed by a dedicated reading device different from the photographed image. When the reference image is imprinted on the top or last of the film, a special reading device is not required, and control may be performed so that only the image frame is not printed. When there is a reference image corresponding to each frame, the static scanner uses a film carrier as shown in Fig. 6 to enable simultaneous measurement of parts other than the photographed image part, and separates the photometric value for each area to perform the arithmetic processing. What should I do? 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 further ensure the effects of the present invention, it is preferable that the photographic material used here has little variation in processes other than the color printing process. Specifically, by the time change from the production of the photosensitive material to the development processing, or by the time change from the exposure of the photosensitive material to the development processing,
Alternatively, it is preferable that the performance does not change due to a change in time from the production of the processing solution for the photosensitive material to the development processing.

The unmanned very high rate of the present invention, for example, 10%
It provides a system that can obtain color images with a pass rate of 0 percent, thereby enabling a system that can obtain color prints at stores, such as with vending machines. Thus, if the development process is rapid, the prints can be returned immediately, thus increasing the effectiveness of this system.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In a color image forming method according to the present invention,
A specific example of a method of recording a standard gray image on a part or all of the color photographing material outside the photographing screen and reproducing the photographed image on which the gray image is recorded on a display will be described. The method of reproducing the photographed 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 tube 111, and then illuminates the color negative film 12 of the present invention from behind. As shown in FIG. 1, a color negative image composed of a photographed image 12a and a reference image 12b on the color negative film 12 is taken by a color TV camera 113, and a red video signal R, a green video signal G, a blue video Converted to signal B. These video signals are converted by the γ correction circuit 114 into γ
After the correction, the image is converted into a positive image by a negative / positive conversion circuit 115 and sent to an amplification circuit 116. This amplification circuit 116
The amplification factor is adjusted based on the film image density calculated by the CPU 26. The video signal amplified for each color by the amplifier circuit 116 is added to the memory color signal by the adders 117 to 119, and then sent to the driver 120. This driver
120 drives the color CRT 121 to display on the display surface of the CRT 121 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.

A CPU 126 and a ROM are connected to a system bus 125.
127, a RAM 128, an I / O port 129, and a 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. An amplification circuit 116 is connected to the I / O port 129, and adjusts the amplification factor of each color according to the exposure amount calculated by the CPU 126.

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

The CRT controller 130 has a color T
An address signal is created from the synchronization signal from the V camera 113 and sent to the video RAMs 137a to 137c. The memory color data is sent to shift registers 141a to 141c provided for each color. Each of the shift registers 141a to 141c has eight output terminals, and frame data on a plurality of scanning lines is written. As for the frame data of each color, eight bits forming one pixel are output in parallel, sent to 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, added to the video signals of the respective colors, and image synthesis is performed.

Next, the operation of the above embodiment will be described. First, the CPU 126 reads out the standard size and memory color data from the ROM 127 and stores them in 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 photographed, and video signals of each color are generated. The video signal undergoes γ correction, negative / positive conversion, and brightness adjustment processing in accordance with the amount of exposure for printing, and is then sent to the driver 120 via addition circuits 117 to 119. The driver 120 drives the color CRT 121 to display a positive color negative image on the CRT 121.

The CRT controller 130 generates an address signal from the synchronizing signal of the color TV camera 113, reads out the gray data stored in the memory color video RAMs 137a to 137c using the address signal, and reads the gray data.
Send to 1a-141c. The shift registers 141a to 141c have 8
The bit signals are read out in parallel, and are read out by the D / A converter 14.
Send to 2a ~ 142c. The analog-converted frame signal is sent to adders 117 to 119 to be synthesized.

As shown in FIG. 3, the color CRT 121 displays a positive image in which the reference image is simultaneously fitted along with the memory color gray. By observing the positive image, it is determined whether or not the color of the memory image, for example, the gray image 145 matches the color of the displayed reference image (gray) 146 of the film. If they do not match, the user operates the keyboard 131 to input the two images so that the color densities match. When the correction data is input, the CPU 126 calculates the amplification factor of the amplification circuit 116 for each color in accordance with the correction data, and sends it to the amplification circuit 116. The amplification 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 change. In this way, the color negative display reference image 146 is matched with the color density of the memory color 145.
By matching these two images, the positive image (display image) of the captured image is properly displayed. The memory color 145 may be displayed so as to surround the display image, or may be displayed outside the display image or a part inside the display image, preferably in a small area where the color evaluation can be performed in contact with the display reference image 146. .

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

A video RAM forming the memory color 145
The amplification factor of the amplifier circuit 116 may be automatically adjusted so that the data matches the photographed video signal of the reference image 12b on the film. 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 the automatic adjustment, the keyboard 131 may be operated so as to match the taste of the color and density. Also, memory color 145
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 match 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. Need to be kept. The color of the memory color 145 and the color of the reference image 146 may be any color as long as they are constant. However, a color in which the difference is visually recognizable, that is, gray or flesh color is preferable.

The display image itself can be used for viewing a color film, and there is no need to adjust the display image for each film frame. In addition, 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 of a negative film in a photographic printing apparatus.

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

If the light receiver 52 is constituted by a scanner, The red, green, and blue densities (or values proportional to the densities) are obtained for each point of the reference image 12b and the photographed image 12a, and the arithmetic average of these values is used to calculate the average densities of red, green, and blue, respectively. I do. The obtained average density D _JN of the reference image 12b is stored in the memory 63, and the average density D _J of red, green, and blue of the photographed image 12a is also stored in the memory unit 63.

At 23, the three color light components are adjusted. The printing light whose light quality has been adjusted by the color filters 21 to 23 is sufficiently mixed in the diffusion box 24 and then illuminates the negative film from below. The light transmitted through the color negative film 19 passes through the printing lens 25 and the shutter.
After 26, the exposure position is reached.

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 a stock chamber 34 for storing the exposed color paper 19. This stock room contains rollers
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 unit 37 includes a color developing tank 38, a bleach-fixing tank 39, and three washing tanks 40 to 42. A series of color papers 19 are transported by a number of transport rollers at a constant speed and sequentially immersed in each processing tank, whereby color development, bleach-fixing, and washing are performed. A drying drum 46 and a cutter 47 are disposed on the right side of the photographic development processing section 37. The photographic-developed color paper 19 is subjected to a drying process, and then separated by a cutter 47 into individual frames. (Not shown).

FIG. 5 shows a control system. The negative carrier 18 includes a plate 50 and a mask 51, and holds the color negative film 12 therebetween during printing. In order to measure the three-color density of the color negative film 12, a photodetector 52 is provided. The image is read immediately before photographic printing, and a photographed image 12a and a 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 light receiver 52 is an A / D converter
After being converted into digital signals by 56, they are sent to a logarithmic converter 57. The logarithmic converter 57 converts the input signal into an approximate density signal by performing logarithmic conversion. The data converted to the density signal is sent to the computer 60. This computer 60 has an I / O port 61, a CPU 6
2. It is composed of a memory 63, and performs control of a filter adjusting section 67 and a shutter driving section 68 in addition to taking in density data and calculating an exposure amount.

An example of the calculation of the exposure amount will be described 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 color paper and an automatic color photographic printing machine. D _JI : Exposure correction amount based on image content D _JN : Reference film density D _JI : For exposure control of i-film frame 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) Under slope control coefficient when D _JI −D _JN <0 Over slope when D _JI −D _JN ≧ 0 Control coefficient

II. Photographing and Printing [II-1] Using the samples 101 to 109, a mannequin doll arranged in front of a wallpaper having the same reflection spectrum as white of the Macbeth color checker using a standard white light source as a standard light source was used. After photographing with an appropriate exposure for 1/50 second and performing the development processing shown in Table 1, a color filter was selected for each film so that the print was closest to the original.
Here, Fujicolor Super FA Paper (manufactured by Fuji Photo Film Co., Ltd.) was used as a printing material. Under these conditions, the samples 101 to 109 were photographed under the respective photographing conditions (4 ×
(4 × 2 = 32 conditions), printing was performed using the same filters selected for each of the above films, and only the print time was changed, and each film was evaluated. Here, the color correction coefficient C _j was set to 0.0. Table 4 shows the results.

[0153]

[Table 3]

[0154]

[Table 4]

The pass rates shown in Table 4 are based on the visual judgment of 10 amateur panelists regarding the photographs. "Fail" refers to the level at which amateur photographers do not endure observation and request reprinting for DPE acceptance. Therefore, a pass rate of 100% means that the amateur photographer has taken a snapshot of the person and is at a level where all prints can be received. From Table 4, it was clear that the pass rate of the comparative example was lower than that of 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 the color filters are optimally selected, a film photographed under any light source can be printed under the same filter conditions, and an unmanned printer can be manufactured. From the above, the effect of the reference example is clear.

[II-2] Using the samples 101 to 109, each subject (four conditions) shown in Condition 2 of Table 3 was photographed with each illumination light (four conditions) shown in Condition 1 of Table 3, and was taken off-screen. Is exposed by a C light source so that the development density of the green-sensitive layer becomes fog +0.5, and after the development treatment shown in Table 1, color is applied so that the exposed portion outside the screen becomes 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 described above. Table 5 shows the results.

[0158]

[Table 5]

Table 5 shows that the comparative examples other than the reference example were unacceptable in any of the light sources, making it impossible to make a completely unmanned system.
On the other hand, for the film of the reference example, if the color filter is selected so that the exposed part outside the screen is gray, the film shot under any light source can be printed under the same filter conditions, making it possible to make an unmanned printer . From the above, the effect of the reference example is clear.

[II-3] As in [II-2], samples 101 to 1
Table 3 for each illumination light (4 conditions) shown in Condition 1 of Table 3 using 09
The film obtained by photographing each subject (4 conditions) shown in Condition 2 above and exposing the film to the outside of the screen with a 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, six each were produced. These films were printed according to the following printing conditions.

(Storage conditions) a: Repetition of [II-2] (corresponding to almost ideal storage and development processing of the film) b: The film after photographing was stored in an environment of 50 ° C. and 80% for one week. Developing, same as a. C: Film after shooting is stored in an environment of 50 ° C. 20% for one week, and developing, same as a in the following. D; Film before shooting is stored in a 50 ° C. 80% environment for one week and shooting. And e is the same as a except that the developing temperature is lowered by 3 ° C. f; is the same as a except that the developing temperature is raised by 3 ° C.

(Printing conditions) Method 1; all of a to f are printed with the same filter as a. Method 2; a color filter is selected such that each of a to f becomes gray on the exposed portion outside the screen, and printing methods 1 and 2 are used. Table 6 shows the obtained results.

[0163]

[Table 6]

From Table 6, it can be seen that, according to the reference example, when both the saturation reproduction index and the Bizecki index are satisfied, the pass rate of the obtained print is surely increased (method 1). Furthermore, if the method of selecting the color filter that prints the exposed portion of the screen outside in gray and printing the image portion from Method 2 is applied, the performance changes before and after the film is shot, or the development conditions fluctuate. It can be seen that even when the photographic performance changes, a print with a pass rate of 100% can be obtained, and the effect of the reference example is clear. In particular, an unmanned printer can be achieved with a passing rate of 100%.

According to the same principle, the observed reproduced image is CR
It is clear that even with a display such as T, satisfactory color reproduction can be obtained by reproducing the photographic material in the range of the reference example such that the exposed portion outside the screen becomes gray.

REFERENCE EXAMPLE 2 Films obtained under the same developed conditions a to f as in Reference Example 1 were automatically printed by the following method.

Method I: Automatic color printer FAP3500
(FUJI FILM) for high-collection printing Method II; automatic color printer (same as above) for low-word collection printing Method III; each of the films obtained in a to f is grayed off the exposed area outside the screen Table 7 shows the above results.

[0168]

[Table 7]

In the method I, the frame of the person arranged in front of the white wallpaper has an acceptable finish under each of the conditions a to f. However, the frame of the person arranged in front of the blue, green, and red wallpapers is acceptable. Faces are yellow, magenta, and cyan, respectively.
A pass rate of 0% was not possible. In the 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 obvious. Method
In III, the finish was acceptable for all the frames under each of the conditions a to f, and the pass rate was 100%.

As described above, according to the reference example, good results can be obtained. In particular, according to the method III, a print with a pass rate of 100% can be obtained. Is also possible.

Example 1 A film obtained under the same developed storage conditions of a to f as in Reference Example 1 was used for Champion 23VE (Fuji Film
V-Accs of Minilab Printer Processor Co., Ltd.)
Displayed on the monitor. The memory color data was set so that the outer periphery became a reference gray. A gray image created outside the film screen was displayed on the V-Acs monitor, the color was adjusted by the operation unit so as to be the same color as the outer peripheral portion of the display image on the monitor, and then the film image was displayed under the conditions. 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, the results were insufficient with a photograph of a fluorescent lamp or the like, and the effect of the present invention was clear.

[0172]

According to the present invention, the deviation in color reproducibility due to the difference in light source, the deviation in color reproducibility due to color feria, etc. are better corrected overall and the pass rate of the obtained color image is further improved. be able to. Further, according to the present invention, the pass rate of the obtained color image can be reproduced at 100%, particularly by using the method of recording the reference image outside the photographing screen, and a complete 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 with good color reproducibility at a constant finish without the need for human color adjustment.
