Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a novel processing member for developing a silver halide photographic light-sensitive material, an image forming method using the same, and a digital image information producing method.

[0002]

2. Description of the Related Art A silver halide photographic light-sensitive material (hereinafter, also simply referred to as a photographic light-sensitive material, a light-sensitive material or a light-sensitive material) is used for other light-sensitive materials because of its high sensitivity and excellent gradation. Because they have very superior properties, they are widely used today. In particular, silver halide color photographic light-sensitive materials are very excellent recording materials for recording, appreciating and preserving image information because they are inexpensive, have good image quality, and have excellent image storability. It is recognized by the market.

On the other hand, with the spread of personal computers (PCs) in recent years, there has been a strong demand for obtaining high-quality digital images simply, quickly and inexpensively. A digital camera can easily take a digital image and easily take image information into a personal computer and enjoy it. However, since the number of pixels is small, the image quality is poor and is not satisfactory. Digital cameras with a large number of pixels are also commercially available, mainly for business use, but are expensive and could not be a means for general users to obtain digital images at low cost.

In some cases, digital image information is obtained by taking a picture using a silver halide photographic light-sensitive material and reading a negative film or color paper using a scanner. When a photographic photosensitive material and a scanner are used, a relatively high-quality digital image can be obtained, and the system can be said to be an excellent system in that image assets accumulated as conventional photographs can be utilized.

[0005] In this case, the development processing is usually performed with a small variation in the conditions of the development processing under sufficient control by an administrator or a person who operates the development processing apparatus. The reason why it is required to minimize the fluctuation of the condition for the management of the development processing condition is that a large fluctuation of the condition leads to a fluctuation of the read signal. However, recently, for the convenience of users, there is an increasing demand for installing a developing apparatus in a place where the processing conditions are hardly frequently managed, such as a convenience store or a store or a street which is not directly related to the photographic industry. .

[0006] On the other hand, there is an increasing demand for simplification of a processing system for photographic light-sensitive materials.

[0007] With respect to such a request,
No. 12 and No. 6-167775, after color development, perform simple processing without going through the process of removing silver such as bleaching and fixing, and perform reading multiple times using reflected light and transmitted light using a scanner etc. Discloses a method for obtaining image information. In addition, as a processing system,
No. 0-326001 discloses a method in which an image is read by a scanner or the like to produce digital image information without going through a process of removing silver such as bleaching and fixing after color development. A color hard copy can be obtained using various digital output devices based on the image information obtained here. This method is epoch-making in that it reduces the amount of processing solution for photographic light-sensitive materials.However, if the management of the color developing solution is insufficient, fluctuations in image quality cannot be avoided, and uniform image quality can be maintained. In order to obtain the temperature, complicated temperature control of the developer was required.

Further, the present inventors have studied and found that WO
In the development by spraying or coating of a developer as described in JP-A-98 / 19216, the development does not proceed sufficiently because the amount of the developer is the maximum swelling amount of the photosensitive material, and further spraying or coating is required a plurality of times. It has been found that unevenness occurs in the resulting image. Furthermore, in the method of obtaining image information using reflected light, it is difficult to obtain sufficiently differentiated reflected light by liquid processing, and color information is degraded.

[0009] In order to solve this problem, Japanese Patent Application 2000
No. 144509 discloses a technique of performing dry development using a developing sheet containing a monochrome developing agent. The inventors of the present invention have studied and found that it is surely free from complicated solution management and that images can be obtained simply and quickly. However, since the image quality is not sufficient, further improvement in image quality is desired.

[0010]

A fourth aspect of the present invention is characterized in that the silver halide photographic light-sensitive material is a filter silver halide photographic light-sensitive material (hereinafter, also referred to as a filter light-sensitive material). The Journal of Filter Material
Imaging Technology Volume
e10 Number 1 (1984) using a monochrome emulsion as the image recording emulsion layer,
A photosensitive material using a color filter coated with a yellow, green, and cyan stripe color filter array pattern can be used. Further, a positive film using red, green, and blue as a stripe color filter is also known. As the pattern of the filter layer of the present invention, any of a stripe shape and a mosaic shape may be used. The color filter array may be a stripe color filter array in which a set of red, green, blue, and green line patterns is added as a set of red, green, and blue lines followed by a green line. In this case, the number of green lines is twice as large as the number of red and blue lines, and the repetition width of green stripes is reduced. It is possible to bring about an effect.

In the present invention, a photosensitive material comprising a stripe or mosaic color separation color filter array layer from the subject side, and then a photosensitive layer having color sensitivity to the entire visible light can be used. In this case, the color separation color filter array layer can employ various configurations to separate subject information into three primary colors of RGB, such as yellow, green, magenta, and cyan, or yellow, green, and cyan. Alternatively, there is a method of arranging filters of yellow, magenta, cyan, and the like in a mosaic pattern or a stripe, or a method of arranging filters of three colors of red, green, and blue in a mosaic or stripe.

Examples of the method of arranging the filters in a mosaic form include a lattice arrangement method represented by a Bayer arrangement and an arrangement in which triangles, hexagons, and circles are spread. The arrangement of each color may be regular or completely random.

For the production of this color filter, various known methods can be used. Typical color filter manufacturing methods include a pigment dispersion method in which a photosensitive resin layer in which a pigment is dispersed is formed on a substrate, and a monochromatic pattern is formed by patterning the photosensitive resin layer. A method of applying a conductive polymer material, patterning it into a desired shape by a photolithography process, immersing the obtained pattern in a dyeing bath to obtain a colored pattern, dispersing a pigment in a thermosetting resin, A printing method in which R, G, and B are separately applied by repeating printing three times, and then a resin is thermally cured to form a colored layer;
There is an inkjet method in which a coloring liquid containing a dye is discharged onto a light-transmitting substrate by an inkjet method, and each coloring liquid is dried to form a colored pixel portion.

As a method for producing a color filter having a random arrangement, a method described in Japanese Patent Application No. 10-326017 can be used.

When the color information recording layer comprises a stripe or mosaic color separation color filter array layer and a photosensitive layer having color sensitivity to the entire visible light, the color information recording layer covers the entire visible light. In the photosensitive layer having color sensitivity, it is preferable to adopt a mode in which an image that blocks the entire visible light region is formed. The image that blocks the entire visible light region here is not limited as long as it has a function of forming a substantially black image, but in the present invention, the dye reacts with the oxidized form of the developing agent to form a dye. It is preferable to form a black image by using a plurality of types of couplers.

Further, in the present invention, from the object side,
A halogen comprising a stripe or mosaic color separation color filter layer, and then a photosensitive layer which has color sensitivity to the entire visible light and forms a black image corresponding to a latent image after development processing. After obtaining image information corresponding to a scanned black image from a silver halide color photographic material excluding a color separation color filter, an RGB digital color image produced from the color separation image is converted into Lab or L image.
An image forming method for producing a digital color image by converting the L component information to image information corresponding to a black image after converting the uv signal into a uv signal is preferably used.

The total content of gelatin in the silver halide photographic light-sensitive material and the processing member according to claim 5 of the present invention.
The aqueous medium amount Wt given to t is 0.2 <Wt / G
It is characterized in that t <0.8. Preferably, 0.4 <Wt / Gt <0.7. This is because when the amount of the aqueous medium to be applied is small, the developed film and / or
Or the amount of the water-soluble compound supplied from the developing sheet is not sufficient and the development becomes inactive, and the concentration of the water-soluble compound becomes dilute if the amount of the aqueous medium is too large. By becoming inactive.

According to a seventh aspect of the present invention, desilvering is performed after development. In the desilvering treatment, a known silver halide solvent can be used in combination. For example, thiosulfates such as sodium thiosulfate and ammonium thiosulfate, thiocyanates such as potassium thiocyanate and ammonium thiocyanate, and JP-B-47-11386.

In the eighth or ninth aspect of the present invention, reading with an image sensor means reading at the time when the developing process is completed and reading with the photosensitive material developed during the developing process. There are cases.
In particular, when reading is performed during the developing process, the photosensitive material in the course of development is read by an image sensor, or the developed photosensitive material is taken out and read by the image sensor.
It refers to repeating reading, development, reading, and the like.
The development progress state of the photosensitive material to be read may be an initial development state or an over-development state. It is preferable that the image is read by the image sensor a plurality of times.

In this case, "reading by the image sensor a plurality of times" means reading the image by the image sensor twice or more at different development times while the film is being developed (FIG. 1 shows the heating development-reading process). An explanatory diagram is shown). The reading is preferably performed in the early stage of development, the middle stage of development, and the late stage of development (end of development), and the reading may be performed in the overdevelopment period. The reading may be performed during the heat development, or may be temporarily taken out during the heat development and then performed again after the reading. In repeated reading, infrared light is preferably used as reading light in order to prevent printout due to reading of a film, and when reading with visible light, it is preferable that reading is the last of a plurality of readings.

The infrared light used in the present invention refers to light in a wavelength region where the color film is not substantially exposed, and specifically refers to light in a wavelength region of 730 nm or more, preferably 850 nm or more. Since the infrared light used in the present invention does not expose the film, even if the reading is repeatedly performed during the development, the development progress of the film is not affected.

In the present invention, the image sensor is a scanner, a CCD, or the like. The scanner is a device that optically scans a photosensitive material and converts the optical density of reflection or transmission into image information. When scanning, it is common to move the optical part of the scanner in a direction different from the direction of movement of the photosensitive material to scan the required area of the photosensitive material, and it is recommended that the photosensitive material be fixed. Alternatively, only the optical part of the scanner may be moved, or only the photosensitive material may be moved to fix the optical part of the scanner. Alternatively, a combination of these may be used. Also C
Using a CD is also a preferable method in that image information can be read at high speed.

Light sources for reading signal information include tungsten lamps, fluorescent lamps, light emitting diodes, laser beams, and the like.
Tungsten lamps are preferred because they can be used without particular limitation and are inexpensive. In addition, it has stability and high brightness,
Using a laser beam (coherent light source) is also one of the preferable methods because it is hardly affected by scattering.

When reading the image information of the photosensitive member,
It is preferable to measure the amount of reflected light or transmitted light by irradiating the entire surface with infrared light or light in a wavelength region in which at least three dyes can be absorbed or by slit scanning. In this case, the use of diffused light is more preferable than the use of parallel light because information such as a film matting agent and scratches can be removed.

When infrared light is used as a scanner reading light source, it is preferable to read the amount of light using reflected light and transmitted light.
Image information on a photosensitive material can be obtained by a method such as double film scanning described in JP-A-133112 and JP-A-6-167775.

Here, the double film scanning means scanning the film with reflected light and transmitted light from both sides of the film. This scanning is particularly performed on the film of the present invention which is undergoing the heat development processing and has a milky white emulsion. This system provides a means for developing a color film into black and white, and constructing color information obtained by analyzing the black and white image information.

FIG. 2 is an explanatory diagram showing an example of a double film processing system used for reading according to the present invention. On a transparent film substrate 201, three layers (red photosensitive layer 200, green photosensitive layer 21) sensitive to red light, green light and blue light, respectively.
0, blue photosensitive layer 220). In normal color development, a layer sensitive to blue develops a yellow dye, a layer sensitive to green develops a magenta dye, and a layer sensitive to red develops a cyan dye.

During or during development, these layers are milky white. The developed silver particles formed in the upper layer, ie, the blue photosensitive layer 220, can be seen from the front surface (emulsion side) 202 of the film by reflected light 204, but cannot be seen from the back surface (substrate side) of the film due to the milky emulsion. .
Similarly, the developed silver particles of the lower layer, that is, the red photosensitive layer 900 can be seen from the back surface of the film by the reflected light 205 but not from the front surface (emulsion side) 202. The developed silver particles of the intermediate layer, that is, the green photosensitive layer 210 are reflected light 206 from the front surface.
Alternatively, it is hardly visible due to the reflected light 207 from the rear surface. However, they can be detected together with the particles in other layers according to the transmitted light 208,209. By sensing the light reflected from the front and back surfaces and the light that has passed through the film, each pixel in the film gets three measurement numbers that can be solved for three colors. That is, when the transmission density is T, the front reflection density is R _f , and the back reflection density R _r is measured, the blue photosensitive layer, the green photosensitive layer,
The absorption based on developed silver to produce each red-sensitive layer D _B, D _G, When D _R, they are related via the matrix A as shown in Equation 1.

[0096]

(Equation 1)

[0097] Therefore, by obtaining the inverse matrix A-1, the measured values T, R _f, D _B from R _r, D _G, can be determined D _R.

Although this technique can be applied to ordinary color films on the market, special photographic films may be prepared for this purpose.

In the reading of the present invention, FIGS.
The reading device shown in FIG. 5 can be used. FIG. 3-
FIG. 5 shows an example of a reading device used in reading of the present invention.

FIG. 3 shows a pair of line sensors (307, 308, or 3) sandwiching the color negative film 301.
09) and a line sensor (304, 305, or 30)
6) using a plurality of pairs. This figure shows an example in which a plurality of sensors are arranged on one side, but the number of sensors arranged on one side may be one. FIG.
The pair of area sensors 413 and 414 forming a pair with the color negative film 401 interposed therebetween as shown in FIG.
One method is preferably used.

Here, as described above, in order to perform scanning and reading with transmitted light and reflected light (front and back surfaces) using infrared light, the infrared light source 310 arranged on the front surface of the film and the infrared light source 310 on the back surface are used. It is necessary to alternately turn on / off the arranged infrared light source 311. Scanning and reading by the sensor is performed in synchronization with the turning on / off.

As shown in FIG. 5, the color negative film 5
01 and a rotatable cylindrical structure “transparent transport member” 5 which contributes to the transport stability of the color negative film.
15 and the image input medium (504) are also preferably used. The state of the color negative film (for example, “warpage” or “distortion”) is obtained by reading the image input medium on the surface 516 where the “transparent conveying member” 515 contacts the color negative film 501.
To reduce the effect of

It is preferable that a semiconductor image sensor (for example, an area CCD or a CCD line sensor) is used for the light receiving section. As mentioned above, one of the preferred embodiments of the present invention is to repeatedly read the film during or after development with an image sensor. It is preferable to read a film in a state of shallow development, a suitable development point, and an over-development state.

An ordinary color film is composed of three photosensitive layer units sensitive to light in the blue, green and red regions. Each photosensitive layer unit is not composed of a single emulsion layer, but is composed of two or more emulsion layers such as a high-speed emulsion layer and a low-speed emulsion layer, and a middle-speed emulsion layer. In each emulsion layer, silver halide grains having different sizes are used, and the larger the sensitivity, the larger the grain.

It is known that the developing speed of silver halide varies depending on its grain size. Normally, the smaller particles have a higher developing speed, and the larger particles have a lower developing speed. Thus, the slow emulsion layers are usually developed faster than the fast emulsion layers. Therefore, when the development time is short, image information recorded in the low-sensitivity emulsion layer can be obtained, and as the development time increases, the image information in the high-sensitivity emulsion layer is mixed.
In the overdeveloped state, image information recorded mainly in the high-sensitivity layer can be read.

In the repetitive reading in the reading of the present invention, the image recorded on the color film is scanned to read the image information of the high sensitivity layer and the low sensitivity layer, and the signal value (SH) of the high sensitivity layer in each pixel is read. ) And the signal value (SL) of the low-sensitivity layer. When SL is strong, SL is used. When SL is smaller than the usable range, SH is used. When SL is weak but within the usable range, SL and SH are weighted and averaged. Get the value. The signal values thus obtained are gamma corrected to linearize and match their density curves.

The signal value and the image density, and further, the exposure amount are obtained by performing the above operation on the exposed film of which the image density obtained when performing the original color development is known and obtaining SL and SH. You can take correspondence with.
In this way, the image read by the image sensor is repeatedly performed during the development, and the image recorded on the color film can be properly reproduced.

In this image reading method, visible light or non-visible light may be used. However, since light irradiation is performed during development, it is preferable to use light having a wavelength at which the silver halide grains are not sensitive, for example, infrared light.
Either color development or black-and-white development can be used for development, but when reading is performed using infrared light, color development is not necessary, and silver development may be performed. It is preferable that the generated developed silver particles have high covering power, and it is preferable to use black and white development.

The image information thus obtained can be viewed using various image display devices. As the image display device, an arbitrary device such as a color or monochrome CRT, a liquid crystal display, a plasma light emitting display, and an EL display is used.

According to the present invention, an image can be formed on another recording material by outputting a read image information signal.
As a material to be output, various hard copy devices are used in addition to the silver halide photosensitive material. For example, inkjet method,
Various methods such as a sublimation type thermal transfer method, an electrophotographic method, a cycolor method, a thermoautochrome method, a method of exposing to a silver halide color paper, and a silver halide heat developing method are used. The effect of the present invention is sufficiently exhibited by any of the methods.

Further, in the digital image information producing method of the present invention, the digital image information produced as described above can be output as a file to a predetermined recording medium. Specifically, it is delivered to a customer who requests development by outputting a file to mobile media such as MO or ZIP, or digital image information is stored as a file on a hard disk of a server computer such as a photo shop, and a request from a customer who requests development is received. It is possible to cope with a service form such as outputting according to an order.

The main object of the present invention is to take in image information obtained by development as digital image information. However, according to the conventional method, photographed information is converted to a print material such as color paper in an analog manner. Optical exposure can also be used. (Light-sensitive material) The silver halide photographic light-sensitive material according to the present invention has a color development method by color development with a coupler, a color development method by oxidizing a leuco dye, a color development layer having a color filter layer and a silver halide layer. Any method, such as a method of obtaining a color image without performing the above, can be used. In particular, a method of performing color development with a coupler to form a color is preferably used.

The silver halide color photographic light-sensitive material according to the present invention comprises a red-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer and a blue-sensitive silver halide emulsion layer capable of recording red, green and blue light. It is preferable to have an emulsion layer.

An image obtained by the repeated processing of the liquid bath processing and the reading cannot obtain sufficient reflected light, so that color separation is poor and color reproducibility is deteriorated. Further, since the toner is applied to the developer a plurality of times, unevenness occurs in the image. The same was true for the developer spray.
