DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for easily and quickly obtaining a color image from a photographed silver halide color light-sensitive material. More specifically, the present invention relates to a color image forming method and apparatus capable of maintaining the latitude of a photographed silver halide color photosensitive material and obtaining an image having excellent chroma.

[0002]

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. As a result, the time and simplicity that cannot be obtained with the current color film / paper system, and in addition, the mutual conversion between the color image obtained by developing the color film and the digitized image information is quick and simple. The realization of a system that can be performed easily is desired.

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 scanning is sequentially performed as it is, there is a problem that image reading accuracy is insufficient and noise of image information is large. In addition, processing time is required, and the fluctuation of processing performance is large.

On the other hand, JP-A-6-266166 and JP-A-6-266166
Japanese Patent No. 295035 discloses an improved method for improving reading accuracy by providing a reflective layer in a color film. However, the practice of the disclosed method is not practical because of the drawback that ordinary films on the market cannot be applied. In addition, JP-A-9-146647 and JP-A-9-202031 disclose,
A method for obtaining digital image information by scanning and reading from an image obtained by heating and developing a film containing a developing agent is disclosed. Although this method has been solved in terms of rapid and simplified development processing, it does not solve the drawback that a general-purpose film cannot be applied as in the above-mentioned U.S. Patent.

On the other hand, JP-A-11-52528 discloses a method of obtaining digital image information by scanning and reading an image without performing bleaching after color development. This method has a rapid and simplified development process and can be applied to a general-purpose film, and the above-mentioned drawbacks on both sides are improved. However, in recent years, fixed-exposure cameras such as film with a lens (that is, "photographing" and the like) have become widespread, and the number of cameras that do not control exposure over a wide exposure area to be photographed has increased. Therefore, at present, it is necessary to maintain a wide latitude that allows a color film to cover a wider photographing area. Is not supported.

[0006] As described above, it is simple and quick, and can cope with digital handling of image information.
At present, a color image forming system having the same image quality as ordinary color prints such as saturation and wide latitude has been demanded from the market, but has not sufficiently responded to the demand.

[0007]

The features of the method of the present invention described in the above items 1 to 9 are as follows. (1) First, a photographed silver halide color light-sensitive material is subjected to a development process so that each light-sensitive layer (R, G, B light-sensitive layer) is developed. ) To form an image, respectively, and (2) Then, the image elements of the image of one or more photosensitive layers are photoelectrically read by an image scanner to reflect reflected light to obtain electrical image information (referred to as first image information). After that, the image elements of the image of one or more photosensitive layers including another photosensitive layer are photoelectrically read to reflect the light to obtain electrical image information (referred to as second image information). Next, in an image forming method for obtaining electrical blue, green and red digital image information by arithmetically processing the obtained first and second image information, a reading operation of the first image information and a second image information Heat and dry the developed photosensitive material in the middle of It is.

In a color light-sensitive material, when it is wet with a processing solution or the like, a dispersion of minute oil droplets containing a coupler is dispersed in the light-sensitive layer. Since the reflection is large, the discrimination between the non-image part and the image part is improved when reading with reflected light, and accurate image reading becomes possible. When the color photosensitive material is dried, the light scattering disappears and the transparency of the non-image area increases.
The discriminability between the non-image part and the image part when reading with transmitted light is enhanced. The present invention is characterized in that image reading accuracy is enhanced by skillfully utilizing the change in optical properties of the image layer (photosensitive layer) due to dryness and humidity.

That is, both or at least one of the front side and the back side is read as the first image information under the condition that the reading accuracy of the reflected light is high, and then the photosensitive material is heated and dried to increase the transparency, and then the transmitted light is read. Read the image of at least the intermediate photosensitive layer as a second image information under high accuracy conditions, and convert it by arithmetic processing to obtain electrical blue, green, red digital image information,
The effect of this method, which combines the dryness and wetness of the photosensitive layer and the reading method, appears in the improvement of the reading accuracy of image information, the improvement of image saturation, and the speeding up of the process. In addition, since the reading accuracy is maintained over a wide exposure range, the effect of relieving the image quality of an overexposed image, which is likely to occur when shooting with a fixed-exposure camera / film such as "photographing," is particularly significant.

There is no particular limitation on the color light-sensitive material to which the present invention can be applied. However, the light-sensitive material having a polyester support so that the heat drying after reading the first image information is enhanced so that it can withstand rapid drying sufficiently. It is preferred that

The electrical blue, green, and red digital image information obtained by the color image forming method of the present invention can be output to any image means such as color print, ink jet, magnetic or optical recording means. In particular, when the digital image information is further subjected to image processing to improve image quality characteristics and to perform image processing such as image modification, and then applying the image-processed digital image information to the image output means, The effect can be particularly exhibited.

The image information can be read by a scanning method using a line sensor arranged at right angles to the conveying direction while conveying the photosensitive material, or a reading method using an area sensor that simultaneously reads the entire image frame. In the latter case, a device having a reservoir in the transport portion is used so that transport of the film in the read portion can be temporarily stopped during image reading. In addition, by providing a reservoir, for example, the magenta dye image formed on the intermediate photosensitive layer and the cyan dye image formed on the red photosensitive layer on the support side are each read by changing the color sensitivity of the sensor and using one image reading device. Can also be read.

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. In the following description of the image forming method of the present invention, the development usually used in the color photographic market with respect to the development used in the present invention is referred to as a standard development. In the color photographic market, each photo lab receives the products (color photosensitive materials) of each company and develops them using a substantially common developing method. For example, color negative film formulations are CN16 series (designated by Fuji Photo Film Co., Ltd.), C41 series (designated by Eastman Kodak Company, USA), and CNK4 series (Konica Corporation)
Designated prescription). These are considered to be international standard processes even though the process names (product names) are different. 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 of the image forming method of the present invention Development processing 3. Heat drying 4. Image reading 5. 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, a film processing and image reading unit 110 includes a developing unit 111, a first image information reading unit 112 using reflected light, and a heating / drying unit 113.
And a second image information reading unit 114 using transmitted light. The color film F is loaded into the image forming apparatus and transported to the film processing and image reading unit 110, where the development processing is performed in the development processing unit 111, and the respective photosensitive layers (R, R,
(G, B photosensitive layers). Next, in the first image information reading unit 112, a reflected light type image scanner (not shown) photoelectrically reads an image element of at least one of the images on the front side and the back side photosensitive layer to obtain first image information. After the reading of the first image information, the color film F is dried in the heating and drying unit 113 to make the non-image part transparent, thereby reducing the transmission density. In the color film F in which the image contrast of the transmission density is improved by making the non-image portion transparent, the image of the remaining photosensitive layer is photoelectrically read by the transmitted light type image scanner (not shown) in the second image information reading portion 114. To obtain second image information. The obtained first and second image information is in the form of a time-series electric signal,
After being transmitted to the image processing unit 120 and converted into a digital signal so that image processing can be performed, it is converted into electrical blue, green, and red digital image information. The electrical digital image information obtained by the above steps can then be applied to any color image forming means to obtain a color image.

Examples of the color image forming means include color printing using color photographic paper, ink jet, thermal dye transfer, time-series electrical image signals such as images recorded on magnetic recording media in the form of disks and tapes and optical recording media. Any known means that can convert a digital print image into an image can be used, and it is an excellent feature of the present invention that the digital print image can be converted freely. 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.

In 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 stored 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. The details will be described later.

2. 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.

As the coating treatment, a known method such as a coating and developing method such as gravure coating or reverse coating can be applied, but a sheet processing in which the photosensitive material is substantially impregnated through a medium carrying a processing liquid is preferable. one of. As this method, a method described in Japanese Patent Publication No. 2655337 can be exemplified. As the medium for supporting the treatment liquid, felt, woven fabric, metal having slits or pores, or the like can be used. Among them, Japanese Patent Application Laid-Open No. Hei 8-290088,
The method of applying a treatment liquid using a sponge or the like described in JP-A-8-290087 and JP-A-9-138493 is preferable. Other coating treatment methods include a roller coating method and an earbar coating method described in JP-A-59-18153, a method of applying water using a water-absorbing member described in JP-A-59-18354, or a method of applying water. Kaisho 63-
144,354, 63-144,355, 62
-38,460, JP-A-3-210,555, etc., or water.

In the application process, it is often advantageous to impart viscosity to the processing solution in that a required amount of the processing solution can be supplied to the photosensitive material, and in that sense, the viscosity process is a preferred embodiment. As the viscous agent for imparting viscosity to the treatment liquid, an organic or inorganic polymer material that can be dissolved in the treatment liquid is used. Preferred viscosity-imparting agents include hydroxycellulose, cellulose acetate phthalate, water-soluble cellulose derivatives such as carboxyethylcellulose, starch and dextrin, alginic acid, peptin, various natural polymers such as polysaccharides, galactose, sucrose, sugars such as glucose, and polyvinyl. Examples include water-soluble synthetic polymers such as alcohol, polyacrylate, polymethacrylate, butyl methacrylate, and copolymers thereof.

The spray processing, ie, the spray processing, is a method of performing processing by spraying a processing solution onto a photosensitive material.
An advantage is that it is easy to adjust the spray amount of the processing liquid to an amount that can substantially penetrate the photosensitive material. Regardless of the method and method of spraying the processing liquid, the number and shape of the nozzles, the spraying may be performed while moving a single movable nozzle, or may be performed using a plurality of fixed nozzles. Also,
The spray may be performed while the photosensitive material is fixed and the nozzle is moved, or the spray may be performed while the nozzle is fixed and the photosensitive material is moved. Among them, a plurality of nozzle holes for injecting a processing liquid described in JP-A-8-123001, JP-A-9-160208, and JP-A-9-179272 have a plurality of nozzle holes which are arranged at regular intervals in a conveying direction of a photosensitive material or a processing member. A method in which the processing liquid is sprayed by a processing liquid applicator having nozzles arranged linearly along the intersecting direction and an actuator for displacing the nozzles toward a photosensitive material or a processing member on a transport path is particularly preferable. .

Next, the structure of the developer will be described. For the development, either black-and-white development or color development can be used, and a preferred developer can be selected according to the purpose. Since the black-and-white developer has a high developing activity, the developing time can be further reduced, and the color noise of the color image can be increased by suppressing the fog of the non-image area to reduce the image noise. And the developing solution is stable, the processing stain is small, and the management of the solution is easy. On the other hand, when a color developer is selected, an image can be read with a color image, and an image with little color mixture and high saturation can be obtained.

In order to make the distribution of microwaves on the surface of the color film uniform, irradiation is preferably performed while rotating or moving the color film and / or the oscillation source, and the color film is sequentially irradiated by arranging a plurality of oscillation sources. It is also preferable to adopt a method in which the sheet is transported while receiving.

Examples of actual heating and drying are shown below, but the form of heating and drying used in the present invention is not limited to these examples. FIG. 2 is a schematic structural view showing an example in which air drying with hot air and contact heating and drying with a heat roller are combined. The heating and drying unit 180 includes (1) a contact heating unit including opposing rollers 124 and 125 having heat rollers 124A and 125A on one side and an opposing roller 126 for conveyance, and (2) a slit-shaped opening 121 for blowing hot air. The belt conveyor 12 is driven by a motor (not shown).
8, a belt conveyor 128 driven counterclockwise in FIG. 2, a tension roller 191 for applying tension to the belt, and a roller 13 for driving the belt conveyor 128
1. A blow drying unit including a linear portion 128A located above the first portion 1 and serving as a transport portion for transporting the film F, pore slits 162 and 163 for taking in outside air, and a hot air heating portion 165 having a built-in air heater (not shown). 193
Consists of To describe the operation in the drying unit that combines this blast drying and contact heating drying with a heat roller,
The color film from which the first image reading unit 112 has read the image by the reflected light is sent to the heating / drying unit 180 and is subjected to contact heating by the heat rollers 124A and 125A. And carried into the blow-drying chamber 193. In the blast drying section, the slits 162 and 163
Is blown into the outside air, heated to a predetermined temperature in the warm air heating chamber 165, and blows out through a blower tube (not shown) in close contact with the upper surface 128A of the belt conveyer. (Shown) to blow hot air toward the color film on the belt conveyor. The color film, which has been dried by receiving the contact heating and the hot air blowing, and has a non-image portion made transparent, exits the drying portion 180 via the opposing roller 164 and is sent to the second image information reading portion 114. In the hot air drying unit 193, a part of the hot air injected from the nozzle outlet indicated by the dashed line at the tip of the arrow A is exhausted from the roller 164 mounting portion opened diagonally upward, and most of the hot air heating chamber Returning to 165, it is mixed with fresh air (outside air), circulated by heating.

In the example of the combined drying apparatus of the contact heating method and the hot air blowing method shown in FIG. 2 described above, quick drying can be performed as compared with the drying using only the hot air or only the contact heating. It is considered that rapid drying is possible because the drying resistance of the film is efficiently eliminated throughout the constant rate drying period and the decreasing rate drying period. The air flow is for removing the film to make it in a turbulent flow state. The larger the air amount is, the thinner the film is, the more the heat transfer effect is achieved, and effective constant-rate drying is performed. Therefore, the effect is obtained when the mass velocity is 1000 kg / m ² · hr or more, preferably 1100 kg / m ² · hr or more, and more preferably 1200 kg / m ² · hr or more. It is preferable that the upper limit be 4000 kg / m ² · hr or less due to restrictions on the device. In this case, the mass velocity is used in a commonly used meaning. That is, the density of hot air (k
g / m ² ), the opening ratio of the blowing nozzle (the ratio of the unit area of the heat receiving surface to the sum of the opening areas of the nozzles or slits provided therein), the wind speed (m / sec), and the time / second conversion coefficient (3600 sec) / Hr). In this case, the heat receiving area indicates an area facing the color film of the blow drying unit, that is, an area equal to the film. Further, the heat roller temperature is preferably 40 to 120 ° C, more preferably 50 to 100 ° C. In the blast drying, since the mass speed is dominant in the drying and the influence of the temperature is small, a wide range of temperature from room temperature to 150 ° C. can be selected, but the preferable blast temperature is 40 to 120 ° C., more preferably. 50 to 100 ° C.

FIG. 3 is a schematic structural view of another heating system using both infrared radiation heating and heat roller contact heating.
The color film F, for which the first image reading unit 112 has finished reading the image with the reflected light, is provided with a plurality of heat rollers 1.
The film F passes through the drying unit 18 because the pair of rollers of the heat roller 144 also functions as a transport roller.
The contact heating is performed while being conveyed upward in the casing of No. 0. Further, radiation heating is applied by the infrared lamp 188 and the reflector 189 disposed so as to surround the lamp. The drying unit 180 is connected to the heating unit 18 by the shielding plate 186.
7 and a conditioning chamber 190. A shielding plate (not shown) is provided at an entrance of the heating unit 187 to which the film F is transported, and a shielding plate 1 is provided at an upper end of the heating unit 187.
86 suppresses the dissipation of heat in the heating section. Further, a temperature sensor 184 is arranged at the entrance of the heating unit 187, and an exit temperature sensor 185 is arranged at the exit.

In the condition adjusting chamber 190 above the upper shielding plate 186 of the heating unit 187, warm air is blown from the drying air nozzle 160 and blown out at right angles to the film F, and the state of the dried photosensitive material is changed. Make adjustments. A part of the warm air blown out from the drying air nozzle 160 is guided into the heating unit 187 via a blowing port (not shown), and the heating unit 1
87 is dehumidified. The warm air blown out from the drying air nozzle 160 is supplied by sucking outside air outside the apparatus from an outside air introduction hole (not shown) provided in a casing of the drying unit 187.

In the heating section 187, an inlet temperature sensor 184 and an outlet temperature sensor 18 for detecting the temperature in the heating section 187 are located on the upstream side and the entrance side of the center of the film F in the transport direction.
5 are provided. These two temperature sensors (for example,
Thermistors, thermocouples, etc. 184 and 185 are connected to a control device (not shown), and the control device controls the outputs of the heat roller 144 and the infrared lamp 188 so as to keep the temperature of the heating section 187 at a set temperature.

Next, the operation in the drying apparatus of this embodiment will be described. The film that has passed through the first image reading unit 112 is
The sheet is conveyed to the heating section 187 located on the entrance side of the drying section 187 by the conveying roller pair. In the heating unit 187, the film F is subjected to contact heating while being transported upward by the heat roller pair 144 also serving as a transport roller. The heating temperature of the entrance-side heat roller pair is preferably set to be higher than the heating temperature of the downstream-side heat roller pair.

When the film F is heated by the heater, the film F is heated by contact with the heat roller as described above, and is also heated by irradiating the film F with heat (infrared rays) generated by the infrared lamp heater 188. Heat drying is performed by radiation. Thereafter, the film F is transported to the conditioning chamber 190 above the shielding plate 186, and the film F is sent from the drying air nozzle 160 in the chamber.
After the state is adjusted by the warm air blown toward the second image reading unit 114, the sheet is conveyed to the second image reading unit 114.

The above process is described in terms of water removal.
The film F conveyed to the drying unit 187 receives contact heating from the heat roller 144 and radiation heating of an infrared lamp, and evaporates moisture adhering to the surface. Drying section 18
In the first half of 7, most of the heat supplied to the film F by heat is taken away as latent heat of evaporation, and the surface temperature of the film F is kept constant at a temperature lower than the temperature of the heat roller. After that, the film F is transported to the latter half of the heating section. At this stage, the amount of heat to be supplied is larger than the latent heat taken by the evaporated water, so that the surface temperature of the film F rises (rate-down drying). The infrared lamp increases the internal temperature of the photosensitive layer to promote the diffusion of water, and delays the transition to the reduced-rate drying in which the evaporation rate is reduced, so that efficient drying is performed.

In this embodiment, the film F can be dried quickly and efficiently. In addition, since heating is performed at high temperature for a short time, there is no increase in the unit consumption of energy consumption, and there is no increase in noise or cost.

The development processing was performed by black-and-white development, and the first image information was recorded on the back side photosensitive layer obtained by reading from the back side and the image information recorded on the front side photosensitive layer obtained from the front side of the photosensitive material. A method in which two types of image information, that is, image information contained in all photosensitive layers, are simultaneously read as transmitted image light as second image information. 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 method, a method in which development processing is performed using 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. The developing process performed on the photosensitive material is a color developing process, the first image information is one of the front side or the back side photosensitive layer of the photosensitive material, and the second image information is the front side or the back side of the photosensitive material. A system in which image information is obtained by reading the other of the photosensitive layers and the image recorded on the intermediate photosensitive layer. An advantage is the separability between image information by using the color developer described above. When 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, or a dedicated image reading device may be used. May be performed.

This is a photosensitive material having at least one photosensitive layer provided on a support. A typical example is a silver halide photographic light-sensitive material having at least one light-sensitive layer comprising a plurality of silver halide emulsion layers having substantially the same color sensitivity but different sensitivities on a support. It is. The light-sensitive layer is a unit light-sensitive 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 the unit light-sensitive layers is generally A red-sensitive layer, a green-sensitive layer, and a blue-sensitive layer are provided in this order from the support side.

Further, a reservoir and a first image information reading unit, a heating and drying unit, and then a reservoir and a second image information reading unit are arranged in this order on the transport path, and the transport path is a film that has been read from the second image information reading unit. Was changed so that the path for discharging the wastewater and the path for returning the wastewater to the desilvering processing tank of the development processing apparatus could be selected.

Therefore, the flow of the color film in this device is as follows. That is, after the color film is developed in the developing tank, the development is stopped in the coating tank for the stop solution, sent out from the coating tank by the transport mechanism, and reaches the first image information reading unit via the reservoir. Then, the first image information is read. After this reading, the color film reaches the heating and drying unit by the transport mechanism and is dried. The dried color film reaches the second image information reading unit via the reservoir along the transport path, and the second image information is read by the transmitted light.

The heating and drying section is provided with a combined drying apparatus for infrared drying and contact electric heating drying using a heat roller as shown in FIG. 3, and the temperature sensor 185 shown in FIG.
° C. At this time, the drying time is 7 seconds in the heating chamber 187 and 10 seconds in the passing through the conditioning chamber 190, which is rapid drying for a total of 17 seconds.

The color film which has been read in these two ways may be discarded in the method of the present invention. However, in addition to obtaining an image in the form of digital image information or a color print in which the information is output, development is performed. In this experimental apparatus, the original stabilizing baths (1) and (2) are further replaced with a bleach-fixing bath and filled with a bleach-fixing solution. Is filled with a stabilizer. Therefore, it is possible to desilver the film after image reading in a bleach-fixing tank, stabilize the image in a stabilizing bath, pass through the drying unit, and obtain a developed film with the same image date as that processed in a color lab in the market. it can.

[Table 4]

As can be seen from Table 4, in the negative of Comparative Example-1 which was dried by performing only the developing treatment, the image in the image area and the image in the non-image area could be recognized both visually with reflected light and transmitted light. However, the non-image portion was high in density and lacked in discriminability. Almost no image was obtained by color printing. In Comparative Example-2 in which the first and second readings were performed without drying and image processing was performed, improvement was observed, but the image quality was still extremely insufficient, and was particularly remarkable in a super-exposed area of +6 stops. Met. Example 1 of the present invention in which image processing was performed by reading the second image information after performing the heating and drying was shown to have image quality almost equal to or higher than that of the reference example of the standard processing. Moreover, the processing of Example 1 of the present invention has a short number of steps and is superior in simplicity and quickness as compared with the standard processing.
In addition, there is an economical advantage that no processing agent for desilvering or stabilizing bath is required.

Each sample was evaluated for image quality in the same manner as in Example-1.
The test results are shown in Table 5.

[0295]

[Table 5]

As shown in Table 5, the sample of Inventive Example-2 had the same sufficient image quality as the Reference Example described above in Table 4, and Comparative Example-3 was a very unsatisfactory evaluation result. Inventive Example-1 using the color developer shown in Table 4 and Table 5
From the comparison of Inventive Example-2 using the black-and-white developer, the use of the black-and-white developer gave a good evaluation reflecting the fact that the development processing was quicker and the obtained image quality was less fogged. I have. In addition, a long-term experiment showed that the stability of the developer was high despite the low replenishment rate.

Example 3 Inventive Example-3 In Inventive Example-2, the color film after the first image reading was taken out, the heating and drying unit was switched to a commercially available microwave oven, and high-frequency heating was performed for 10, 20, A test was performed in the same manner as in Example 2 of the present invention, except that three levels of 30 seconds were performed, and the second image was read again by being placed on the transport path.
The results were evaluated. In addition, cotton was supplied at the corner of the electromagnetic wave irradiation chamber to prevent empty burning. When the heating time was 10 seconds, the surface of the color film was dry. Also, 10
There was no sign of overdrying on the surface of the color film with a drying time of 30 seconds, and there was little increase in curl. That is, the additional advantage that the tolerance to the fluctuation of the drying load is large was recognized. The color print obtained in this test is
Any of the drying times of 10 to 30 seconds is substantially the same as Example 2 of the invention

[0298]

According to the present invention, after the processed color film is developed, the image information is read by the reflected light, the image information is read by the transmitted light after the film is heated and dried, and red, blue, and green are read based on both the read information. 2) The method of the present invention for obtaining digital image information makes it possible to speed up the development processing step, and has excellent saturation and gradation as compared with a known method of reading an image without heating and drying. Quality images can be obtained. Further, as an additional advantage, the processing step is only a developing and rinsing step, and no processing agent for desilvering or stabilizing bath is required, which contributes to resource saving and environmental load reduction.
