DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple and quick color image forming method using a photographed silver halide photosensitive material, and to a method for reading a color image and converting it into digital image information easily. More specifically, the present invention relates to an image forming method capable of accurately reading image information having excellent sharpness in a short time and converting the digital image information into digital image information to be used.

2. Description of the Related Art In the color photographic market, a so-called color film or color film is obtained in which a photographed color light-sensitive material (hereinafter also referred to as a color film) is developed in a photo lab and the obtained image is printed on photographic paper to obtain a color print. Paper systems are usually used. Recent trends in the color photography market include (1) decentralization of development sites, that is, collecting and developing color films from stores such as photo shops,
From a conventional centralized large-scale photo lab (large lab) that passes completed color prints to customers via photo shops, to a store lab (mini-lab) that develops customer's film at stores and delivers color prints on the spot Due to the trend of decentralization and (2) the spread of digital photographic images, that is, the emergence of digital minilabs that handle photographic images digitally, electronic recording of film images and printing from electronically recorded digital image sources The spread of services is becoming remarkable. However, with regard to the above (1), it is a fact that the time taken from receiving a color film from a customer to handing over a completed print has been significantly reduced due to the decentralization of development sites by the minilab, but it still takes about 30 minutes. Among them, film development requires 10
It currently takes more than a minute. In addition, since the developing solution is used, maintenance is troublesome and there is little room for simplification. Regarding the above (2), the digitizing service of film information takes time (for example, several days), and the service base is limited. For this reason, the extremely rapid and simple operation, which cannot be achieved with the current color film and paper systems, and the digital image processing of color images obtained by developing color films, have enabled the conversion to various image media. There is a need for a system that can be deployed quickly and easily.

In order to meet this need, international applications WO 98/19216 and WO 98/25399 develop a color film in black and white, scan an obtained image with reflected light and transmitted light, and read a color image from each image information. A method for constructing an image is disclosed. In this method, since the color film is brought into contact with the developing solution while being conveyed, and the scanning is sequentially performed as it is, there are disadvantages that the image reading accuracy is insufficient, the noise of the image information is large, the processing time is long, and the processing fluctuation is required. Is also big.

On the other hand, JP-A-6-266066 and JP-A-6-266066 disclose
Japanese Patent No. 295035 discloses an improved method for improving reading accuracy by providing a reflective layer in a color film. However, the implementation of the disclosed method is disadvantageous in that general-purpose films available on the market cannot be applied, and the disclosed measurement method has large light scattering at the time of measurement, making it difficult to perform accurate reading.

[0005] As described above, it is simple and quick and can handle digital handling of image information.
At present, a color image forming system having the same image quality as general-purpose color prints such as saturation and wide latitude has been demanded from the market, but has not sufficiently responded to the demand.

[0006]

According to the prior art, which reads the image information of a developed film photoelectrically, when reading the image information, the absorption of the intermediate layer in the photosensitive material becomes a background and the reading accuracy is reduced. Lowering the resolution, the colloidal silver particles give noises, deteriorating the resolution, lowering the discrimination of image information, increasing the image density, making it difficult to read the image, However, even if one of them could be solved, it was difficult to solve all of them, which hindered practical application. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an image forming method capable of accurately reading image information having excellent sharpness from a photographed color film in a short time, converting the read image information into digital image information, and using the converted image information.

[0007]

Means for Solving the Problems The present inventors have intensively pursued the possibility of solving the above-mentioned problems by a combination of a photosensitive material technique and an image reading method, and as a result, achieve the object of the invention by the following methods. I was able to. That is, the present invention is as follows.

[0008] 1. A developed silver halide color light-sensitive material having at least one intermediate layer containing an infrared absorbing dye is subjected to development processing, and the first image information is photoelectrically read from the obtained image using reflected light, and transmitted. A color image reading method for photoelectrically reading second image information using light and converting the read first and second image information into electrical blue, green, and red digital image information.

[0009] 2. 2. The color image reading method according to the above item 1, wherein the color light-sensitive material has an antihalation layer containing a decolorable antihalation dye.

[0010] 3. 3. The color image reading method according to the above 1 or 2, further comprising subjecting the electrical blue, green, and red digital image information obtained by converting the first and second image information to image processing. .

4. The first image information includes two types of image information: image information recorded on a back side photosensitive layer read from the back side of the photosensitive material, and image information recorded on the front side photosensitive layer read from the front side of the photosensitive material. 4. The method for reading a color image according to any one of the above items 1 to 3, wherein

5. The color image reading method according to any one of claims 1 to 4, wherein the reading light of the first image information is infrared light.

6. It reads photoelectric image information using reflected light from the image of the developed silver halide color photographic light-sensitive material and photoelectric image information using transmitted light, and converts both read information into digital image information. A silver halide color photographic light-sensitive material comprising at least one intermediate layer containing an infrared absorbing dye at a transmission density of at least 0.05.

7. The support had at least one silver halide emulsion layer, at least one intermediate layer containing an infrared absorbing dye having a transmission density of at least 0.5, and an antihalation layer containing a decolorable dye. Characteristic silver halide color photographic material.

The features of the method of the present invention are as follows. (1) First, a developed silver halide color light-sensitive material is subjected to a development process to form an image on each of the three light-sensitive layers (R, G, and B light-sensitive layers). (2) Subsequently, an image information reading device such as an image scanner photoelectrically reads an image element of an image of both or at least one of the photosensitive layers on the front surface side and the back surface side of the photosensitive material with reflected light to obtain an electrical image. Information (referred to as first image information), and an image element of an image of a photosensitive layer, such as an intermediate photosensitive layer (usually, a G photosensitive layer), which has not been read by reflected light, is photoelectrically read by transmitted light to obtain electrical information. Obtaining image information (called second image information), (3)
Then, in an image forming method for obtaining electric blue, green, and red digital image information by performing arithmetic processing on image information read by reflected light and transmitted light, an infrared absorbing dye is contained in an intermediate layer of a photosensitive material to be applied. Thus, the above-mentioned problem has been solved.

A method in which a color film is subjected to development processing, an image is read from the image, and the subsequent processing step is not performed, has a remarkable effect in simplifying the development processing of the color film and reducing the required time. . On the other hand, when the image information is read photoelectrically at the stage of completion of the developing process, accurate reading is performed due to the remaining colloidal silver fine particles, overlapping of the image information of other layers, light scattering by the developed silver, and the like. This makes it difficult to reduce image quality factors such as resolving power, color turbidity, and color reproducibility. The method of the present invention using a color film containing an infrared dye in the intermediate layer leaves the image layer on the reading side more than the intermediate layer and works to eliminate noise on the back side, so that the quality of the read image is improved. The object of the present invention is to solve both the simplicity and speed of image access and the securing of image quality.

Further, when this color film contains an infrared dye in the intermediate layer and a decolorizable dye which decolors in the development process instead of the black silver fine particles in the antihalation layer, the transmitted light Of the second image information can be read without the adverse effect of the anti-halation layer having a high transmission density, so that the reading sensitivity and accuracy of the second image information can be improved, and the object of the invention is further exhibited. Can be done. In addition, functions that depend on the infrared absorption ability of the antihalation layer, such as detection of a color film in a developing machine and adjustment of film frame feed in a camera, which will be described later, are prevented by the intermediate layer containing an infrared absorbing dye, so that trouble is avoided. .

According to the image forming method of the present invention, not only an image can be obtained simply and quickly, but also the obtained digital image information is further subjected to image processing to improve the quality of the digital image information. Image forming method. With the addition of image processing, output to various color prints such as silver halide color print, ink jet, color thermal transfer, etc., storage in various image recording media such as light, magnetism, and semiconductor devices, and use of images between them Can be more effectively performed.

Combinations of first and second image information reading devices and image layers to be read to prevent image information from interlacing between image layers and to accurately extract image information from each image layer; How to combine the absorption wavelength of the absorbing dye with the reading light, and the details of preferred embodiments of the antihalation layer containing the decolorable dye will be described later.

[0020]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described in detail below, but before that, some explanations of terms used in the present invention will be added. As a measure of the effect of the color image forming method of the present invention, since it is commercially available but needs to be compared with the image quality of color prints,
The concept of "standard development" is used, and the development normally used in the color photographic market is called "standard development". That is, in the color photographic market, development processing is carried out using a development processing method which is substantially universal so that each lab can accept the products (color photosensitive materials) of each company (for example, the color negative film formulation is CN16).
(Prescribed prescription by Fuji Photo Film Co., Ltd.), C41 (prescribed prescription by Eastman Kodak Company, USA), CNK4
(Konica's designated prescription is almost common). This is the content of the standard development.

In general, the “development process” includes a broad sense of “development process”, which refers to a series of processes for developing a photographed photosensitive material, fixing an image, and obtaining a stable image, and a development process therein. In the present invention, “development processing” refers to the latter, that is, “development processing” in a narrow sense in principle. The term "development processing" in a broad sense is described as "development processing of a color film", but when it is clear from the context, the "development processing" in a broad sense may also be referred to as "development processing". Further, in the following description, "development processing"
And "image processing", two "processing" with different contents
Are referred to as “processing”, and where there is a possibility of causing confusion, they are expressed separately from “development processing” and “image processing”.

Now, with the above as a preamble, a specific description of the present invention will be made in the following order. 1. 1. Process flow and preferred embodiment of the image forming method of the present invention 2. Intermediate layer containing infrared absorbing dye 3. Antihalation layer containing decolorable dye Development processing 5. 5. Read image Color light-sensitive material used in the present invention and related supplementary explanations

1. First, the outline of the flow of the method of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram schematically showing the flow of the steps of the method of the present invention. In FIG. 1, the image forming apparatus includes:
The developing unit 111 includes a developing unit 111 that performs a developing process, a first image information reading unit 112 that uses reflected light, a second image information reading unit 114 that uses transmitted light, and an image processing unit 120 that processes the read image information. First image information reading unit 1
12, only one is shown in the figure, but one may be provided on each of the front side and the back side of the film. The color film F is loaded into the image forming apparatus and subjected to development processing in the development processing unit 111, and images are formed on the front side, the back side, and the three intermediate photosensitive layers sandwiched therebetween. In FIG. 1, a hopper coating development in which the developing solution D is supplied onto the film by a coating method (indicated by hatching) is illustrated.
Various developing methods can be used as described later.
Next, the first image information reading unit 112 photoelectrically reads the image elements constituting the image by a reflected light type image scanner (not shown) to obtain first image information. The first image information may be both the image layer on the front side and the image layer on the back side of the film, or may be either one of the information. In the latter case, the image layer not read as the first image information is read by the next transmitted light. After reading the first image information, the color film F photoelectrically converts the image of the photosensitive layer that has not been subjected to the first reading by the transmitted light type image scanner (not shown) in the second image information reading unit 114. It is read and second image information is obtained. In FIG.
The arrangement is such that the first image information reading unit 112 using the reflected light is performed before the second image information reading unit 114 using the transmitted light, but this order can be changed. The obtained first and second image information is transmitted to the image processing unit 120 in the form of a time-series electric signal, and is converted into a digital signal so that image processing can be performed.
It is converted to green and red digital image information. Note that the first and second terms regarding image information reading are convenient terms for each image information reading using reflected light and transmitted light, and there is no special meaning between one and two,
Either image reading may be performed first.

In the present invention, reading by reflected light can be applied to the front and back image layers. The infrared absorption effect of the intermediate layer removes background noise when reading an image with reflected light, so that the image layer on the front side and the image layer on the back side of the photosensitive material are each improved in image discrimination when reading with reflected light. This is also convenient for separating and extracting image information to be read by transmitted light of the image of the intermediate layer sandwiched between the two image layers, so that highly accurate image information can be obtained. The effect of performing this processing for reading the first image information under the condition that the reading accuracy of the reflected light is high is particularly effective in relieving the image quality of an overexposed image, which tends to occur when shooting with a fixed exposure camera.

In the present invention, infrared light can be used for reading the first image information by the reflected light. Since the infrared dye in the intermediate layer eliminates noise inside the intermediate layer, the effect of selectively extracting information of the image layer on the front side can be effectively exhibited, which is preferable. The present invention provides an intermediate layer containing an infrared dye in both the lower photosensitive layer of the blue-sensitive photosensitive layer and the upper photosensitive layer of the red-sensitive photosensitive layer, the blue photosensitive layer on the front side of the photosensitive material and the red photosensitive layer on the back side of the photosensitive material Can be read in a noise-free state to improve the reading accuracy.

According to the present invention, the spectral spectrum region of the infrared ray for reading the first image information and the absorption wavelength region of the infrared absorbing dye in the intermediate layer are overlapped to reduce the background noise at the time of reading the image. Reading may be performed under high spectral conditions.

When the color film containing an infrared dye in the intermediate layer further contains a decolorizable dye in the antihalation layer, the transmission and transmission of the first image information by the reflected light are improved in addition to the improvement of the sensitivity and accuracy. The reading sensitivity and accuracy of the second image information by light can also be improved, and the object of the invention can be further exhibited. The antihalation layer contains black colloidal silver fine particles, which are usually black (neutral color) and has high light absorption, and has the function of removing halation light. It has a function to respond to the infrared sensor for adjusting the film frame advance. However, it is necessary to remove this colloidal silver in the desilvering step after the developing step. When the present invention is applied to a color film containing black colloidal silver fine particles in the antihalation layer, the second image information is read in a form in which the high transmission density of the antihalation layer is superimposed, so that the reading sensitivity and reading accuracy are limited. Is done.

A color film in which the colloidal silver fine particles in the anhalation layer are replaced with a decolorizable dye having a property of losing light absorption ability during the development process is also known in recent years. Originally, the purpose is to reduce the load of the desilvering process and to shorten the desilvering time. When the above-described image reading of the present invention is applied to the color film having the anhalation layer, the sensitivity of the second image information reading by transmitted light is improved. Although the accuracy can be improved, there is a problem in that the ability to detect the photosensitive material in the developing machine and the function of adjusting the film feed in the camera are reduced.

However, when a color film containing an infrared dye in the intermediate layer and a decolorizable dye in the antihalation layer is applied to the image forming method of the present invention, the second image information read out by the transmitted light can be obtained. At the time of reading, the image information is not superimposed on the transmission density of the antihalation layer, and for reading of the first image information by reflected light, as described above, the intermediate layer containing the infrared dye has the quality of the read image. Therefore, both the first image information and the second image information can be read with high accuracy, and the digital image information converted from the read image also has high quality. In addition, the above-described problems of deterioration of the photosensitive material detection capability of the developing machine and the function of adjusting the film piece feed in the camera are not accompanied.

In the present invention, black and white development may be used. When the effect of the present invention is a black-and-white image in which the image is composed of silver, the discrimination of the image is improved by removing the reflective silver image of the surface layer and the background noise due to light absorption, thereby improving the accuracy. be able to. With black and white development,
Since advantages such as shortening of development time, prevention of developer contamination, and simplification of developer management can be obtained, it is possible to achieve both improvement of image quality and simplicity and quickness of image forming operation. Further, as an embodiment in which infrared light is also used as the reading light for the second image information, when light having a longer wavelength region than the light absorption region of the infrared dye in the intermediate layer is used as the reading light for the second image information, the absorption of the infrared dye is reduced. The reading accuracy can be improved, and the reading speed can be increased. In order to exhibit the effect, it is preferable that the absorption maximum of the reading light and the infrared dye of the intermediate layer be apart from each other by 20 to 400 nm. When two or more types of infrared absorbing dyes are used, it is desirable that the above relationship be satisfied for each dye. If both maximal wavelengths are closer than 20 nm, the absorption regions overlap,
If the distance is more than 400 nm, the sensitivity of the reading device is reduced, so that the reading sensitivity is lowered and the accuracy is deteriorated.

In order for the color light-sensitive material to exhibit the above effects, the infrared dye added to the intermediate layer has an absorbance in the light absorption region of 0.05 or more, preferably 0.2 or more, and 4.0 or less. , Preferably 2.0 or less, and from the standpoint of ensuring resolution, etc., the thinner the intermediate layer is, the better it is. Therefore, the requirement of the intermediate layer that satisfies both requirements is that the molecular absorption coefficient is At least 1 × 10 ³ cm ² /
at least 0.05m
A silver halide color photographic light-sensitive material having an intermediate layer containing mole / m ² , and a preferable infrared absorbing dye is
The molecular extinction coefficient is 2 × 10 ^{4 to} 5 × 10 ⁷ cm ² / mol
e, and the coating amount in the intermediate layer is 0.2 to 5.0 mmo.
le / m ² . A dye having a higher molecular extinction coefficient can require a smaller amount of the dye applied to give the same concentration. If the absorbance of the infrared absorbing dye exceeds the above range, the sensitivity is lowered. If the absorbance is less than this range, the effect of the invention cannot be obtained.

The electrical digital image information read and converted by the above steps can then be applied to any color image forming means to obtain a color image. Color image forming means includes color printing using color photographic paper, ink jet, thermal dye transfer, recording of images on magnetic recording media and optical recording media in the form of disks and tapes, and the like. Any known means capable of conversion can be used, and it is an excellent feature of the present invention that the digital image information and the print image can be freely converted. In the image forming method of the present invention, the color film is only required to be subjected to a development process as a development process, and if it is a conventional general-purpose process, a subsequent process such as desilvering or a stabilizing bath is performed following the development process. There is no need for it, and therefore the processing steps for color films are extremely simple and fast, satisfying the objects of the present invention.

Further, according to the present invention, since an image is obtained in the form of digital image information, it is not necessary to save the color film after development. After image reading is completed, desilvering processing such as bleaching and fixing processing or bleach-fixing processing and stabilizing bath processing are performed, and a long-term storable developed film similar to a color film obtained by standard development processing can be obtained. it can. There are various combinations of reading the first image information using the reflected light and reading the second image information using the transmitted light, and a preferable form can be selected according to the purpose.

In the present invention, the infrared absorbing dye is used in the form of solid fine particles. In order to obtain solid fine particles, a known disperser can be used. Examples of the dispersing machine include a ball mill, a vibrating ball mill, a planetary ball mill, a sand mill, a colloid mill, a jet mill and a roller mill. The disperser is disclosed in JP-A-52-92716.
And International Patent Publication No. 88/077944. Vertical or horizontal media dispersers are preferred. Dispersion may be performed in the presence of a suitable medium (eg, water, alcohol). It is preferable to use a surfactant for dispersion. As the surfactant for dispersion, an anionic surfactant (described in JP-A-52-92716 and International Patent Publication No. 88/074794) is preferably used. If necessary, an anionic polymer, a nonionic surfactant or a cationic surfactant or a cationic surfactant may be used. The method for dispersing the infrared dye and the material such as the surfactant used for the dispersion are substantially the same as the dispersing method and the material for the decolorable dye described in the following section (3.). explain.

After dissolving the infrared absorbing dye in a suitable solvent, the poor solvent may be added to obtain fine powder. Also in this case, the above-mentioned surfactant for dispersion may be used. Alternatively, dissolve by adjusting the pH, then p
By changing H, microcrystals of the dye may be obtained. When a lake dye is used, (D) of the above formula (II) at an appropriate pH value
Dissolving a dye such as corresponds to -A _n, then the formula (I
Fine crystals of the lake dye may be precipitated by adding a water-soluble salt of a cation corresponding to Y in I). For more details on the method of dispersing the above-mentioned infrared absorbing dye and the material such as a surfactant used for dispersion, the method for dispersing the decolorable dye described in the next page (Section 3.) and the material for dispersing are substantially the same. Therefore, duplicate description is avoided here.

The infrared absorbing dye is added to a silver halide emulsion layer or a non-photosensitive hydrophilic colloid layer of a silver halide photographic material. The non-photosensitive hydrophilic colloid layer includes a back layer, a protective layer and a subbing layer (of a support).
It is preferably added to the back layer or the protective layer, more preferably to the protective layer. An infrared absorbing dye may be used in combination with another dye. For other dyes,
It is described on page 17 of JP-A-2-103536.
As the hydrophilic colloid used in the silver halide emulsion layer or the hydrophilic colloid layer, gelatin is most preferable. Lime-treated gelatin, acid-treated gelatin, oxygen-treated gelatin, gelatin derivatives and modified gelatin are used. Lime-treated gelatin and acid-treated gelatin are preferred. For other available hydrophilic colloids, see JP-A-6-67338.
On page 18 of this publication.

In the present invention, by using fine (crystal) particle dispersions of the dyes represented by the above general formulas (I) and (II), the dissociation with the conventionally known dissociated anionic dye is prevented. A hydrophilic polymer having a charge of m is coexisted in the same layer as a mordant, and a so-called mordant method for fixing dye molecules or a dispersion or latex of oil-soluble dyes dispersed in water or a gelatin solution in fine particles using a high-boiling organic solvent is used. In the method using a dispersion, there is an adverse effect such as desensitization on photographic properties due to diffusion of the dye to another layer due to insufficient fixation of the dye, and a residual color after development processing due to insufficient decolorization. The problem that unnecessary absorption remains as color and surface quality is reduced is improved.

3. Antihalation layer containing a decolorizable antihalation dye Next, a decolorizable antihalation layer which is preferably used in an antihalation layer of a color light-sensitive material to which the present invention is applied and has a remarkable effect on the object of the present invention. The halation dye will be described. A dye effective as an antihalation dye is such that when used as an antihalation layer, the antihalation layer has a thickness of 400 to 700 n.
m has a minimum absorbance of 0.2 or more in a wavelength range of m,
In addition, the dye can have a ratio of the highest absorbance to the lowest absorbance of 5 or less. Preferred dyes are from 420 to 470
nm, 530 to 570 nm and 610 to 640 nm
Is a dye having an absorbance in the wavelength range of 0.3 or more, more preferably 0.5 or more.
Particularly preferred are dyes which provide an absorbance in the range of approximately 0.7 to 1.1 over the wavelength range from 420 to 640 nm. The decolorizable antihalation dye is
It is a dye that decomposes and decolors in color developers such as color developers and various black-and-white developers, and the decolorization of the dye by the developer depends on the alkali, hydroxylamine, and sulfurous acid contained in the developer. This occurs when a dye reacts with a treatment liquid component such as ions to decompose and discolor the dye, or effluent, or to lose part or all of the absorbance due to both. Dyes that can be used as decolorizable antihalation dyes are dyes that have a decomposition rate of 50% or more based on extraction and quantification during the development reaction of a photosensitive material using the dye for the antihalation layer. The preferable decomposition rate is preferably 70% or more, more preferably 90% or more from the viewpoint of color reproducibility. When measuring the decomposition rate of the dye, the dye was dissolved and extracted to prepare a calibration curve, the remaining amount of the dye was determined by HPLC, and the decomposition rate was determined according to the following equation.

Decomposition rate = (residual amount of dye after development processing) / amount of dye extracted before development processing)

The dyes may be used in combination of two or more dyes in order to satisfy the requirements of the light absorption characteristics. The dye referred to in the present invention may be an organic compound or an inorganic compound irrespective of its structure, but is preferably an organic compound in that the decomposition reaction in a developer is relatively fast. An organic compound such as an organic dye and an inorganic compound such as colloidal silver can be used in combination within the scope of the present invention.

When a light-sensitive material prepared using a dye which is not decomposed by a developing solution is color-developed and an image is read without bleaching, these dyes are not sufficiently decomposed. However, it has been found that there is a problem in reading image information. In particular, it has been found that the remaining yellow coloring is a major obstacle to reading image information formed by the yellow coloring coupler.

The processing solution used in the present invention is not particularly limited. However, it is more preferable to supply the processing solution with an amount of the processing solution that can permeate the photosensitive material so that no waste liquid is generated. The method of supplying the processing liquid to the photosensitive material is not particularly limited, but it is preferable to perform spraying or coating development.

The structure of the dye used in the present invention is not particularly limited as long as it has the decomposability according to the present invention.

4. Development Processing Development processing is performed regardless of the processing method, its method, and conditions.
For example, any known method and method such as immersion development, coating development, and spray development can be used. Above all, a method in which only a processing solution that can permeate the photosensitive material and is supplied to the photosensitive material for processing is preferable because no waste liquid is generated. As a method for supplying a small amount of liquid, there is a method in which a photosensitive material is immersed in a processing liquid, and then an excess processing liquid is removed with a squeeze roller. This method is disclosed in JP-A-9-15.
Preferred are the methods described in JP-A Nos. 819, 9-15820 and 9-15822. There is no particular limitation on the method of supplying the treatment liquid, but it is preferable to apply a coating treatment or a spray treatment.

This method utilizes the fact that image information recorded on the photosensitive layer on the front side and the back side of the photosensitive material has high reading accuracy with reflected light. It is also advantageous that the developing solution is highly active, stable, and relatively easy to maintain.

In the above-mentioned reading system, a developing process is carried out with a color developer. In this case, the sensor for reading the second image information is adjusted according to the color image (normal magenta) recorded on the intermediate photosensitive layer, and the image information of the intermediate photosensitive layer image can be selectively extracted. The separation between them is improved, and image characteristics with high saturation can be obtained.

Or, a method in which image information is obtained by reading from the other of the back side photosensitive layer and the image recorded in the intermediate photosensitive layer. By using the color developer, the reflected light reading sensor can be adjusted to each color image, and the separation between image information is advantageous.

In the case where reading of the first image information or the second image information is image information of a plurality of photosensitive layers, the same image reading device may be used repeatedly.
In addition, reading may be performed using a dedicated image reading device.

Images of the film F at different positions (for example, positions shifted by one frame) may be read. That is, the irradiation positions of the light sources 11 and 81 are made different, and the focal positions of the CCD area sensors 15 and 85 are made different so as to image the film F having different irradiation positions.

Further, the wavelengths of the light sources 11 and 81 may be made different from each other so that the CCD area sensors 15 and 85 respond to the wavelength of the corresponding light source. In this case, CC

The frame image (two-dimensional) can be read electrically. Although the description has been mainly focused on the area CCD, the area CCD can be replaced with a line CCD instead of the area CCD. When a line CCD is used, the film F need not be transported at the image frame pitch, but may be transported continuously. The line CCD has a function of accumulating electric charges in accordance with light received by the line pixels, in which a plurality of pixels for detecting light are linearly arranged along the width direction of the film F. (1D) is read electrically.

The first and second image information reading units 112,
Light sources applicable in 114 include tungsten, fluorescent lamps, light emitting diodes, laser light,
In particular, an infrared light source (wavelength: 800 nm to 1200 nm,
(850 nm to 1100 nm) is preferred. This is because the film of the present invention has an intermediate layer having an infrared-absorbing dye, and when reading image information by reflected light, background noise is removed by the infrared-absorbing action, so that image identification accuracy is improved. When reading image information with transmitted light, setting the wavelength of the light source to a longer wavelength region than the light absorption region of the infrared absorbing dye can eliminate infrared dye absorption, improving image reading accuracy. I do.

The first and second image information reading units 112,
The first and second image information read at 114 are input to the image generator 60.

FIG. 4 shows the structure of the image generating section 60, which includes memories 61 and 62 for storing first image information, a memory 63 for storing second image information,
The linear conversion unit 64 that weights the red, green, and blue image information included in the blue image information and the second image information with a predetermined coefficient by a known linear conversion, performs an addition process based on the weighted result, and outputs red, green, An adder 65 is provided for separately deriving blue monochromatic image information. The digital image data of each color obtained by the image generation unit 60 is output to the digital image processing unit 70.

FIG. 5 shows a schematic configuration of the digital image processing section 70. The digital image processing unit 70 is capable of inputting image data obtained by photographing with a digital camera 71 or the like. The digital image processing unit 70 is capable of inputting image data obtained by reading a transparent original, a reflective original, or the like with a scanner 72, or a computer or the like. Thereafter, the floppy disk drive 73, the MO drive or the CD drive 74 is stored in the recording medium.
And image data (image file data) input through communication via the modem 75 and the like.

The digital image processing unit 70 stores the input digital image data in the memory 76, and performs image processing such as various corrections in the color gradation processing unit 77, the hyper processing unit 78, the hyper sharpness processing unit 79, and the like. Then, the image data is output to a printer (not shown) as image data for recording. Even if the image quality of the original image developed by this image operation or the read image is inferior, the image correction of gradation and saturation is performed. The digital image processing unit 70 stores the image data on which the digital image processing has been performed as image file data in a storage medium (for example, FD, MO, CD) and outputs the same to the outside, or to the outside via a communication line. It is also possible to output.

Further, a keyboard 70K is used as an input device.
And a monitor 70M. While viewing the display on the monitor 70M, an image can be captured by the key operation of the keyboard 70K and various image processing can be performed.

The above-described image reading is performed when the first image information reading unit 112 reads the image from the front and back sides twice and the second image information reading unit 114 reads the image from the film F by reading once. explained. This method can be applied not only to the image reading of the black-and-white developed film described above but also to both the color-developed films.

However, especially when reading an image on a color-developed film, the second image information reading section 114
In, by controlling the wavelength of the light source 31 so as to obtain the density information of the photosensitive layer of a desired color, a color image recorded on the intermediate layer can be selectively extracted. further,
When reading an image of a color-developed film, the wavelength of the light source 31 is controlled so as to obtain image information on one of the front and back sides of the film by one reflection reading and obtain density information of a photosensitive layer of a desired color. Thus, the image information of the other side of the film and the intermediate layer may be obtained by two transmission readings.

In this case, the first image information reading section 112
In the case where the image information carried by the red photosensitive layer on the support side of the film F is read, the second image information reading unit 114 firstly reads the image information carried by the blue photosensitive layer located on the front side. The second time, the wavelength of the light source is set so as to read the image information carried on the intermediate green photosensitive layer.
Accordingly, the first image information includes red image information, and the second image information includes blue and green image information. Alternatively, when the first image information reading unit 112 reads the image information carried by the blue photosensitive layer on the front side of the film F, the first image information reading unit 114 is located on the support side for the first time. The wavelength of the light source is set so as to read the image information carried on the red photosensitive layer, and the second time the wavelength of the light source is set so as to read the image information carried on the middle green photosensitive layer. Accordingly, the first image information includes blue image information, and the second image information includes red and green image information.

Further, as described in JP-A-56-25738 and JP-A-62-63936, the layers can be arranged in the order of blue-sensitive layer / GL / RL / GH / RH from the side farthest from the support.

As described in JP-B-49-15495, the upper layer is a silver halide emulsion layer having the highest sensitivity, the middle layer is a silver halide emulsion layer having a lower sensitivity, and the lower layer is a layer having a higher sensitivity than the middle layer. An example is an arrangement in which a silver halide emulsion layer having a low sensitivity is arranged, and an arrangement is formed of three layers having different sensitivities in which the sensitivities are sequentially decreased toward the support. Even when such a three-layer structure having different photosensitivity is used,
As described in JP-A-59-202464, in the same color-sensitive layer, the layers may be arranged in the order of medium-speed emulsion layer / high-speed emulsion layer / low-speed emulsion layer from the side away from the support. Others
High-speed emulsion layers / low-speed emulsion layers / medium-speed emulsion layers, or low-speed emulsion layers / medium-speed emulsion layers / high-speed emulsion layers may be arranged in this order. The arrangement may be changed as described above even in the case of four or more layers. Further, the intermediate layer containing an infrared absorbing dye is preferably provided between the blue photosensitive layer group and the green photosensitive layer group or between the green photosensitive layer group and the red photosensitive layer group, or both, but is not limited thereto.

[0298] 4. Method of photographic property test The following three tests were performed to evaluate photographic properties. (1) Image Sharpness and Shading Property The image sharpness test was performed by an MTF frequency response characteristic test method for rectangular waves based on the JIS method. At that time, the response characteristic values at frequencies of 40 lines / mm and 8 lines / mm were used as a measure of sharpness. (2) Sensory evaluation Each test film was exposed to a standard C light source described in ISO5800 (sensitivity measurement method for color negative film) under standard illumination, underexposure of 1/2 and overexposure of 4 times the standard. At three levels of exposure, a person was snap photographed against a gray wall and developed under the above-mentioned development processing conditions to produce a negative film of an image for evaluation. A print of a color image for evaluation was obtained from the negative image thus obtained. The total image quality is emphasized with emphasis on the color saturation and gradation of the color print for evaluation.
People were scored by the following five-point scale, and evaluated by the average score.

Very poor and unacceptable. ... 1 point Slightly inferior and unacceptable. ······ 2 points Relatively inferior, but acceptable. ··· 3 points Relatively excellent and preferable.・ ・ ・ ・ ・ 4 points Very good. ... 5 points

[0300] 5. Test results The test results are shown in Table 3.

[0301]

[Table 3]

As can be seen from Table 3, Sample 101 of Comparative Example containing no infrared absorbing dye had low image sharpness and unsatisfactory sensory evaluation of image quality, but residual silver fine particles were observed in the developed sample. This is considered to be the effect. On the other hand, Samples 102 to 111 using the infrared absorbing dyes listed as exemplary compounds gave better results than Comparative Examples over all evaluation items, and had satisfactory image quality especially in the sensory evaluation. The sample 112 using the known infrared absorbing dye (a) having an absorption wavelength shorter than the preferable range of application to the present invention (730 nm) is the sample 102 to
Samples 113 and 114 using known infrared-absorbing dyes (e) or (f), whose resolution is slightly inferior to that of 111, and whose dye remaining ratio is lower than the preferred range of application to the present invention.
Also, the resolution was slightly inferior to Samples 102 to 111, and the sensory evaluation was slightly lower due to color turbidity, etc., but none of the samples had better functionality and resolution than Sample 101 to which no infrared absorbing dye was added. Sex evaluation was obtained. Further, when these are compared with a standard development sample of Sample 101 shown as a reference example considered to be representative of the average quality in the market, the method according to the present embodiment can be performed even though the latter step of the development processing is omitted. While maintaining or rather improving the image quality,
Moreover, it was shown that simplicity and quickness, which were the objects of the present invention, were achieved.

[Embodiment 2] The color development processing step in Example 1 was replaced with the following black-and-white development processing step, and the wavelength of the reading light for the second reading was changed from 1100 to 1
The test of Example 1 was repeated without any changes, except that an interference filter of a chromium vapor-deposited film having a transmission band at 180 nm was used. The specifications of the processing and reading process and the prescription are as follows. (Processing process) Step Processing time Processing temperature Replenishment amount * Tank capacity Black-and-white development 60 seconds 38.0 ° C 10 ml 10.3 L Rinse (water bath) 13 seconds 38.0 ° C 10 ml 3.6 L Transfer via reservoir First image information reading reservoir Via second image information reading

[Black-and-white developer] [Tank solution] Nitrilo-N, N, N-trimethylenephosphonic acid / 5 sodium salt 1.5 g Diethylenetriaminepentaacetic acid / 5 sodium salt 2.0 g Sodium sulfite 30 g Hydroquinone potassium monosulfonate 20 g Potassium carbonate 15 g Potassium bicarbonate 12 g 1-Phenyl-4-methyl-4-hydroxymethyl-3-pyrazolidone 1.5 g Potassium bromide 2.5 g Potassium thiocyanate 1.2 g Potassium iodide 2.0 mg Diethylene glycol 13 g Add water 1000 ml pH 9.60 pH was adjusted with sulfuric acid or potassium hydroxide. Table 4 shows the test results. Table 4 shows that image quality almost equal to that of Example 1 was obtained despite black-and-white development. Therefore, when black-and-white development is applied to the color image forming method of the present invention, there are advantages such as easy management of the developer, less occurrence of development stains, shorter development time, and the like. It was shown to be no worse.

[0305]

[Table 4]

Example 3 For the sample 102, the color development in Example 1 was performed by reading the first image information only for the red photosensitive layer (cyan image layer), and the blue photosensitive layer (yellow image layer) The image was read by transmitted light using an image reading device provided with the device. A color print with little color turbidity was obtained, and the sensory evaluation of the practical skill was almost the same as in Example 1.

Example 4 In the sample 102 of Example 1, instead of adding black colloidal silver to the first layer and the second layer, Exemplified Dye III-3 was added to the first layer in an amount of 0.2 mmol / m ² ,
Sample 115 was prepared in the same manner as Sample 102, except that Exemplified Dye III-3 was added to the second layer at a concentration of 0.1 mmol / m ² . Table 5 shows the results of evaluation of this sample by performing tests in the same manner as in Example 1. Table 5
Are the results of the samples of the present invention. In addition to using the infrared absorbing dye-containing intermediate layer, the sample 115 using the antihalation layer in which the black colloidal silver fine particles were replaced with a decolorable dye was black. For sample 102 using an antihalation layer containing colloidal silver fine particles, the image sharpness was improved, and the visual evaluation showed that the image quality was clearly improved over a wide exposure range from the under-exposed area to the over-exposed area. I have.

[0308]

[Table 5]

[0309]

After the photographed color film is developed, image information is read by reflected light and transmitted light.
In the image forming method of obtaining digital image information of red, blue and green based on both read information, sharpness and color saturation are obtained by using a photographic color photosensitive material containing an infrared absorbing dye in an intermediate layer. It is possible to accurately read image information having excellent image quality such as degree in a short time and convert it into digital image information. According to the image forming method of the present invention, since an image is obtained in the form of digital image information, it can be developed not only for color printing but also for various image media such as electronic image means. In addition, the use of a decolorizable dye in the antihalation layer further improves image quality such as sharpness and saturation, and adversely affects the ability to detect photosensitive materials in a developing machine and adjust the frame advance without a camera. Has no effect.
