Abstract

PROBLEM TO BE SOLVED: To obtain an easy photographic system to positive from positive by which processing can be executed at a store such as a mini-laboratory without increasing a space and a cost and which can be made compatible with an N/P system by converting an image to electrical image information in a process that the image of a direct positive type photographing material processed in common with a negative type photographing material is outputted to a print material. SOLUTION: The image information is previously converted to an electrical image signal based on a density value and converted to a digital signal by an A/D coversion part 18 through an amplifier 17. This information signal is transmitted to an image processor 5 through a log converter 20 after it is corrected 19 by a CCD function. According to the read density of a picture frame, the image information of the direct positive image is converted to the image on the prestage of the processor 5. Continuously, the image signal information of every picture frame is processed according to a control condition used in common for a direct positive film and a negative film. By the processor 5, the electrical processing of the image information converted to the digital signal is executed so as to correct image quality.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming method for obtaining a color print from a photographed silver halide color light-sensitive material and a developing apparatus used for the method. More specifically, the present invention relates to a color image forming system capable of obtaining a color print by developing a color negative film and a direct positive film with the same developing processor.

[0002]

2. Description of the Related Art The most widely used form of color photography at present is a so-called negative print, in which a color negative film that has been photographed is developed in a photo lab and the resulting film image is printed on photographic paper to obtain a color print. It is a paper system (hereinafter, referred to as an N / P system). This form is widely spread internationally, and is a system that is convenient and convenient for users to use with various services. However, in this system, the user's interest is of course in the print, and the processed negative film is often not used once printed. In addition, it is troublesome to extract a negative screen which is also necessary for reprinting so that it is difficult to see.

On the other hand, if the photographic material is of a positive type, the value of the material itself after development is increased, and even when a print is desired, a necessary screen can be easily extracted. However, a positive-to-positive system that obtains a positive image by reversing the color reversal film to obtain a positive image and print it on reverse color paper as desired, although existing, has another inconvenience. ing. In other words, color reversal development is performed for both photographic materials and positive materials, but color reversal development can be performed in large-scale laboratories due to the long processing time and complexity, but it is possible to use small-sized color laboratories called minilabs. This system is difficult to implement in a laboratory and is therefore inconvenient for ordinary users. In addition, it is difficult to have both a negative paper system and a color reversal / reversal paper system in a minilab in terms of space, cost, and productivity.

[0004] If a negative type photographic material and a positive type photographic material can be developed by the same developing machine, it is effective in at least the first stage, that is, the common development system of the photographic material. Japanese Patent Application Laid-Open No. 62-139548 proposes that a negative color light-sensitive material and a direct positive color light-sensitive material are processed by the same developing processor. However, this method requires light irradiation to directly invert the image of the positive-type photosensitive material, and the matching of the optimum halide composition in the developer for the negative type and the direct positive type is insufficient. There are disadvantages such as there. JP-A-2-50157, JP-A-2-5
No. 0158 and JP-A-2-64632 disclose a direct positive color photographic light-sensitive material using an internal latent image type silver halide emulsion and a negative type silver halide color photographic light-sensitive material with the same color developing solution. A technique for performing this is disclosed. These disclosures show that direct positive and negative working photographic materials can be processed with the same color developing solution using a specific processing ratio, a specific preservative, and a specific coupler. However, these are applied to an internal latent image type silver halide emulsion as a printing material, and it is extremely difficult to maintain and stabilize the performance of common processing of a photographic material having a large amount of silver coating material. Developing a direct positive photosensitive material and a negative photosensitive material for the purpose of photographing with the same developing processor is high in value, but is also a difficult task from a practical point of view.
If printing can be easily carried out from the developed direct positive type photographic material, the value of use is even greater, but no attempt has been disclosed yet.

[0005]

As described above, if a positive-positive system in which a photographic material is developed in a positive mold and a color positive print is obtained from the photographic material can be performed as easily as an N / P system, direct positing of a photographic film can be performed. Images are also available,
In addition to the fact that color prints were obtained and their utility value was high, they did not spread because of the complicated development processing and the already established N
This is because the system becomes independent from the / P system, and the service system using the positive-to-positive system is not yet fully established. Accordingly, it is an object of the present invention to provide a simple positive-to-positive photographic system that is compatible with an N / P system, does not increase space and cost, and can be processed at a store such as a minilab. .

[0006]

As a result of repeated studies, the inventors of the present invention have found that the object of the present invention is to output an image of a direct positive type photographic material subjected to common processing with a negative type photographic material to a print material. It has been found that it is effective to combine a means for converting an image into electrical image information, more preferably a digital image processing means, in the process, and based on this, the present invention has been achieved. That is, the present invention is as follows.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a direct positive color photographic material (hereinafter referred to as a direct positive film) having an internal latent image type silver halide emulsion which has not been previously fogged on a support, and to a support. A negative color photographic material having a surface latent image type silver halide emulsion layer (hereinafter referred to as a negative film) is processed by the same development processor, and the resulting image is printed on a color positive material to perform color printing. Image forming method. First, a direct positive photographic material having an internal latent image type silver halide emulsion layer which has not been previously fogged, that is, a direct positive film used in the present invention will be described.

The direct positive type photographic material includes a method of reversing using solarization, a method of reversing development by light intensification when light is irradiated by covering the inside of the particles in advance, and a method of the present invention. There is a method using an internal latent image which is not fogged by light, which is a target, but the former two methods have low sensitivity and are not suitable for the photographing purpose of the present invention. On the other hand, a silver halide grain having an internal latent image which has not been fogged in advance is
When irradiated with light, photoelectrons are captured inside and an internal latent image grows but is not developed.In an unexposed portion without light irradiation, a surface latent image grows and becomes developable, and photographing sensitivity is obtained. , Known as prior art. Therefore, in the present invention, a photosensitive material using a direct positive photographic emulsion composed of silver halide grains having an internal latent image which has not been previously covered is suitable as a high-sensitivity direct positive photosensitive material for photographing. This photosensitive material will be described in more detail later.

On the other hand, a negative type color photographic material having a surface latent image type silver halide emulsion which is subjected to development processing using a common development processor, that is, a negative film, is a commonly used color negative film for camera photography. When a photosensitive nucleus distributed on the surface is irradiated with light, a surface latent image having a high development efficiency is formed, so that the photographic photosensitive material can obtain a high sensitivity that can be photographed. As mentioned earlier, this photosensitive material has an internationally established system for undertaking development and print production anywhere in general color development laboratories in the market. Developing machines and developing recipes are also virtually universally shared. In spite of the fact, the surface latent image type photographic emulsion is referred to as a conventional emulsion conventionally produced with respect to the internal latent image type photographic emulsion. A crystal is formed in the usual way, and if it is chemically sensitized, a photosensitive nucleus is formed on the surface and a latent image can be formed on the surface when exposed, so it is a surface latent image type emulsion, and if the latent image is developed, it becomes a negative image. It is also a negative emulsion. A typical example of applying it to a color negative film is
The product names are a series of commercially available color negative films such as Fuji Color Negative Super G Series (manufactured by Fuji Photo Film Co., Ltd.) and Kodakala Gold Series (manufactured by Eastman Kodak Company, USA). Further details of the negative film will be supplemented later.

In the present invention, the developing method may be any of the color developing treatment formulas for color negative film processing, color paper processing, general use, and motion picture generally used in the market (provided that the fogging agent is treated). Except for processing for a color reversal film contained in a liquid), a developing method for processing a color negative film is particularly preferable. Among them, C which can be said to be the internationally common treatment prescription that is widely spread internationally
N16 series (general-purpose prescription of Fuji Photo Film Co., Ltd.), C4
Series 1 (U.S. Eastman Kodak general-purpose prescription), CN
K4 series (a general-purpose prescription of Konica Corporation) and similar treatments are convenient. The details of the development prescription will be described further below and will be shown in Examples, but the main point is that a p-phenylenediamine derivative is used as a color developing agent, and hydroxylamine or a derivative thereof and a sulfite are used as a preservative. Added as
This is a processing formulation comprising a developer having a pH of about 9.8 to 10.4, a buffing solution, a fixing solution, a washing or stabilizing bath. Among the p-phenylenediamine derivatives of a color developing agent, 3-methyl-4-methyldiphenylamine is used in terms of sensitivity and discrimination ability between an image area and a fog area.
Amino-N-ethyl-N- (β-hydroxyethyl)-
Aniline or a salt thereof and 3-methyl-4-amino-N-
Ethyl-N- (β-methylsulfoaminoethyl) -aniline or a salt thereof is preferred. This developing agent can be easily obtained because it is commonly used as a developing agent for color negative films for general photography in various parts of the world.

Further, in the present invention, a developing machine used in common for both a direct positive film and a negative film, apart from an image processing section described later, is capable of developing both photographic materials as far as the developing process is concerned. Any developing machine may be used as long as it can be developed. Two different photographic materials,
The technology for processing with a common developing machine is disclosed in Japanese Patent Application Laid-Open No. 60-1297.
No. 47, JP-A-60-129748, JP-A-61-1
No. 34759, JP-A-62-50828, etc., and these developing machines can be used in the present invention.
In the present invention, the developing step does not need to be specially modified for common processing, and may be a commercially available developing machine, and particularly preferably a developing machine usually used in the market for color negative development. Further, among them, a developing machine for a minilab is convenient.

In the present invention, there are the following methods for obtaining a print using a positive image directly obtained from a positive film. A method of making prints by directly converting positive film into electrical image information using positive / positive color positive materials. A method of directly reading image information of an image obtained on a positive film, converting the image information into digital information, performing image processing, and printing on a negative color print material, for example, color paper.

First, in the method (1), a print is created through conversion into electrical image information. The operation of converting an image into an electrical signal by reading the image with a scanner or the like is performed prior to output to a positive material. That is, it is only necessary that the printer has the function, and it is not necessary to have the image reading and conversion function in the developing device or the independent image processing device. Color positive materials that can be printed directly from a positive film by such a printer include a direct positive silver halide photosensitive material (for example, the same direct positive film used for photographing), a heat development type dye diffusion transfer method [for example, "Pictro Color ", a product of Fuji Photo Film Co., Ltd.], a dye diffusion transfer method (for example," Photorama ", a product of Fuji Photo Film Co., Ltd.), ink jet, dye sublimation type thermal transfer method, diazo color-copy method [for example," Thermoautochrome ", a product of Fuji Photo Film Co., Ltd.], and a commercially available dedicated printer can be used to obtain a print using them. In addition, a reversal color paper that performs reversal color development processing can be applied, but for that, a new development processing step is required, and the effects of the present invention are poor.

Next, in the first method, the negative / positive relationship is inverted by density conversion processing in the first stage of image processing, and the positive image obtained from the photographing material is printed on a negative type color paper or the like. Since a color print can be obtained by a developing processor for color printing, it is not necessary to newly prepare a developing machine for producing color prints, which is a particularly valuable method. This method can be further divided into two types according to a method of directly discriminating between a positive film and a negative film. One is directly from the density of the non-image part of the positive film,
Alternatively, identification is performed based on other information, and the other is identification based on the shape of the density distribution of pixels read for each screen frame. In either method, the film directly identified as a positive film is subjected to a density conversion process from a positive type to a negative type in the first stage of image processing,
The converted digital image information is subjected to an image processing operation common to negative and direct positive images.

In the present invention, it is most desirable to obtain a color print by printing each image of a direct positive film and a negative type color film obtained by processing with the same developing processor on the same kind of color printing material. This is possible because the image on the direct positive film is also image processed to be compatible with a printer for color positive materials by image processing. Particularly, the common color positive material is color photographic paper (also referred to as color paper; reversal color paper is not included), and in particular, when the same type of color photographic paper is used, the advantages of the present invention can be exerted, which is preferable. The same type refers to one having the same product name, and is the same type even if the manufacturing lot, gradation grade, surface type, and size are different.

Further, since the difference between a positive film and a negative film can be directly overcome by image processing, when both films are processed by a common development processor, the processing solution, the processing steps and the processing time of each step are all reduced. Can be common. Particularly preferable processing is a development processing which can be incorporated into an N / P system in which a service system of a development laboratory is established internationally, that is, the above-mentioned CN16 series, C
That is, common development processing is performed in general color negative processing such as 41 series. The color developing agent used in this processing is the aforementioned 3-methyl-4-amino-N-ethyl-N- (β-
Hydroxyethyl) aniline or a salt thereof.

The means for discriminating between a direct positive film and a negative film will be described in more detail. The following method is used for the identification means. The first method is: 1) reading the density of the non-image portion of the developed photographic material to determine whether the photographic material is a direct positive type or a negative type; If there is a mechanism (FIGS. 11 and 12) for performing an image conversion process from the positive type image information to the negative type image information, the subsequent image processing can be performed by the image processing unit 5 in common with the image of the negative film. In particular, this device 1) reads the density of the non-image portion and determines whether the film is a direct positive type or a negative type. 2) If the film is a direct positive type, the image information is sent to a mechanism for performing image conversion processing. Is input, then 3) image information is read for each screen frame and converted into electrical digital information, and 4) image processing is performed in accordance with image processing conditions through the above-described image conversion processing. An image forming apparatus having a mechanism for outputting image information subjected to image processing to a printer is preferable. The density reading of the non-image portion may be performed by any method. However, photoelectric density reading is preferable because it can be incorporated in an automation system, the size can be reduced, and an image information reading device for each screen can be used in many common parts. The non-image portion to be read can select between the screen frames, between the screen frame and the edge of the film, near the DX raster pattern code, and the like. In particular, it is preferable to read the density near the raster pattern code before the screen frame starts. Since the density of the non-image portion differs between the direct positive film and the negative film, it can be easily identified by measuring the density.

The second method is to read the image information of each frame screen of a direct positive film, which will be described later, and to read the frame screen for performing an image conversion process so that the image information can be output on a negative color photographic paper. In this method, a positive film or a negative film is directly identified from the difference in density distribution of each pixel, and if the film is a direct positive film, image information is sent to an image conversion processing portion. In this case, there is an advantage that the reading of the positive film or the negative film is directly performed while reading the image information of the frame screen.

The third method is a method of inputting support for whether or not to perform an image conversion operation for a positive film directly to the image processing unit by an operator's manual operation. It is desirable that the image forming apparatus is designed so that this operation can be performed as needed without performing this manual operation in normal work.

Regardless of which method is employed, the point of the present invention is that image conversion is performed on a direct positive film, and thereafter, image processing of each of the read images on the positive film and the negative film is performed. Proceed by a common processing unit. Therefore, the process, particularly the image reading, image processing, and output steps, will be mainly described.

Further, in the following description, even though the common terms "processing" of "development processing" and "image processing" are attached, there are two completely different operations. Are expressed separately from “development processing” and “image processing”.

FIG. 1 is a block diagram showing the development processing apparatus of the present invention and the flow of operations therein. The film is taken into the developing device from the left end of the diagram. First, the type of the film is read (0
1). This reading is for knowing the type of the film described in the perforation symbol for identification called DX code on the film, and the setting conditions of the image processing described later are directly determined by the “type” information between the positive film and the negative film. It is also possible to match any of the films. The selection of which condition to set can be made manually by the operator instead of this reading.

The film is transported through a series of processing tanks in the developing machine. The developing machine is preferably of a roller transport type. Even if the same developing machine and the same processing solution are used, if the process needs to be changed, the above-mentioned film reading (01) or the operator's selection operation (0
4) The process can be changed. In the process change, it is convenient to change the transport speed and directly select a bath time suitable for each of the positive-type and negative-type films. Each of the films is subjected to development processing including color development, bleaching, fixing, washing or stabilization in accordance with the selected development processing step, and then proceeds to the image information reading step (1).

In this step, the transmission density (reflection density in the case of a reflective support) is measured for each small area unit (usually called a pixel) constituting the image of the developed film, and the image information is read as the density for each pixel. Can be As a result of the reading, the image information has been converted into an electric image signal based on the density value, and is converted into a digital signal by an A / D (nalog / digital) converter 18 via an amplifier 17. This information signal is subjected to a CCD function correction 19 such as a correction of sensitivity variation and dark current for each pixel, and then a log converter 20.
And sent to the image processing apparatus 5. The identification reading of the positive film and the negative film may be directly performed at this stage, that is, it corresponds to the second method described above. The image information of the direct positive image is subjected to image conversion before the image processing apparatus 5 according to the reading density of the screen frame, and the image signal information for each screen frame is subsequently converted according to the control conditions common to the direct positive film and the negative film. It is processed. In the image processing device, electrical processing is applied to the image information converted into the digital signal to correct the image quality. The present invention is characterized in that the correction of the bias is performed by image processing as described later. The above image processing operation is performed by the method and the arithmetic unit disclosed in Japanese Patent Application Nos. 8-174022 and 8-182551 filed separately.

The image signal processed by the image processing device is output to the printer (8), and as a result, a normal positive image is obtained. The printer may be any printer that inputs an electrical image signal or a photoelectric image signal, but particularly preferred printers are color paper, instant photography, silver salt color printing such as a heat development type dye diffusion transfer method, ink jet, and sublimation type. It is a printer for each positive image such as thermal transfer, wax type thermal transfer, diazo color copy, and color electrophotography.

Negative-working color photographic materials having a surface latent image type silver halide emulsion The photographed color negative photographic materials used in the present invention are all general-purpose color negative films from various manufacturers generally sold in the market. A typical example is a support comprising at least one, usually 3 to 4, photosensitive layers comprising a plurality of silver halide emulsion layers having substantially the same color sensitivity but different sensitivities. Is a silver halide photographic light-sensitive material having The photosensitive layer is a unit photosensitive layer having color sensitivity to any of blue light, green light, and red light,
In a multilayer silver halide color photographic light-sensitive material, the arrangement of unit light-sensitive layers is generally arranged in the order of a red-sensitive layer, a green-sensitive layer, and a blue-sensitive layer from the support side. However, the order of installation may be reversed depending on the purpose, or the order of installation may be such that different photosensitive layers are sandwiched between the same color-sensitive layers. A non-light-sensitive layer may be provided between the silver halide light-sensitive layers and as the uppermost layer and the lowermost layer.

Next, several or more than ten tabular silver halide emulsions are usually used for color photographic materials. Tabular silver halide emulsion grains (hereinafter referred to as "tabular grains") have a value obtained by dividing the value of the average equivalent circle diameter by the square of the average thickness (the degree of tabularization) (JP-A-3-135335).

In addition, it is also a preferable embodiment to use a chelating agent such as 1-hydroxyethylidene-1,1-diphosphonic acid or ethylenediaminetetramethylenephosphonic acid, or a magnesium or bismuth compound.

A so-called rinsing liquid is also used as a washing liquid or a stabilizing liquid used after the desilvering treatment. The preferred pH of the washing step or the stabilizing step is 4 to 10, and more preferably 5 to 8. The temperature can be set variously depending on the use and characteristics of the photosensitive material, but is generally 20 ° C to 50 ° C, preferably 25 ° C to 45 ° C. Drying is performed following the washing and / or stabilizing step. From the viewpoint of reducing the amount of water carried into the image film, it is possible to speed up drying by absorbing water with a squeeze roller or cloth immediately after leaving the washing bath. As a means of improvement from the dryer side, as a matter of course, it is possible to speed up the drying by increasing the temperature or changing the shape of the spray nozzle to increase the drying air. Further, as described in Japanese Patent Application Laid-Open No. 3-157650, drying can be accelerated by adjusting the blowing angle of the drying air to the photosensitive material and removing the exhaust air.
