DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for converting an image signal obtained from a color image or a monochrome image carried on a reflective original such as a photograph or a printed matter, a transparent original such as a negative film or a reversal film into a digital signal. The present invention relates to an image reproducing system for reproducing a visual image on a silver halide photographic light-sensitive material.

2. Description of the Related Art In recent years, image information recorded on a photographic film (hereinafter, referred to as a film) such as a negative film or a reversal film or a printed matter is photoelectrically read, and the read image is converted into a digital signal. 2. Description of the Related Art Development of a digital photo print system that performs image processing to form image information for recording, scans and exposes a photosensitive material such as photographic paper with recording light modulated according to the image information, and prints the image is progressing. Digital photo printers are free to edit images such as combining multiple images and splitting images, layout of printed images such as editing of characters and images, and various types of image processing such as color / density adjustment, scaling, and edge enhancement. The print can be freely edited and image-processed according to the purpose. In addition, in conventional printing using surface exposure, it is not possible to reproduce all image density information recorded on a film or the like due to the restriction of the reproducible density range of the photosensitive material. It is possible to output a print in which almost 100% of the reproduced image density information is reproduced. Such a digital photo printer basically includes a reading unit that reads an image recorded on a document such as a film, determines an exposure condition after performing image processing on the read image, and uses the photosensitive material according to the determined exposure condition. It is composed of image recording means for performing a developing process by scanning exposure and displaying the image on a monitor.

[0003]

In the conventional surface exposure method, high-speed printing is possible because no image reading time or image processing operation is performed. Therefore, when constructing the above-mentioned digital photo printer, it is an important issue to comprehensively improve the productivity in order to compensate for the portion of the surface exposure system inferior in high speed. In order to improve the productivity of digital photo printers, minimize the time from image reading to printing as much as possible, and then automate complicated image processing condition settings and the like, which were previously only possible for skilled workers. It is necessary to reduce the cost and loss of the system. Only by achieving these can high-quality prints be obtained cheaply. However, in the conventional technique, it is difficult to construct the above-mentioned system and obtain a high image quality higher than that of the surface exposure method after making the productivity equal to the surface exposure method. Accordingly, an object of the present invention is to provide an image reproducing system capable of obtaining a higher image quality than that of the surface exposure system while making the productivity of the digital photo printer equal to that of the surface exposure system.

[0004]

Means for Solving the Problems As a result of intensive studies by the present inventors, the following points have been found and high image quality can be achieved. In order to shorten the time from image reading to printing, it has been found that a system using a sensor or a CCD area sensor which does not need to move a document as an image reading means is advantageous. A CCD area sensor is, for example, a large number of 500 or more charge-coupled devices (CCs).
D) A series of sensors. By converting an image into a signal, image sharpening, graininess suppression, dodging (optimization of partial brightness correction), and other high-quality images that were impossible or extremely difficult with conventional surface exposure In conventional surface exposure such as gradation correction and color correction, the correction relying on humans has been substantially automated and productivity has been improved. Silver halide photographic light-sensitive materials are advantageous as high-quality and low-cost printing materials.In particular, silver halide photographic materials using silver chlorobromide emulsions with a high silver chloride content can produce more prints per unit time. Because it can be produced,
More preferred. The exposure to the output silver halide light-sensitive material is preferably a laser scanning exposure method in which the flare and color shift are small and the resolution does not change due to enlargement / reduction of the screen size.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail.
The input color negative photosensitive material used in the present invention may have 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 photosensitive layer is blue light, green light,
And a unit light-sensitive layer having color sensitivity to any of red light and a multilayer silver halide color photographic light-sensitive material. In general, the arrangement of the unit light-sensitive layers is, in order from the support side, a red light-sensitive layer, The color-sensitive layer and the blue color-sensitive layer are provided in this order.
However, depending on the purpose, the order of installation may be reversed, or the order of installation may be such that different photosensitive layers are sandwiched between layers of the same color sensitivity. A non-light-sensitive layer may be provided between the silver halide light-sensitive layers and as the uppermost layer and the lowermost layer.

As the color negative film for input used in the present invention, a conventionally known color negative film can be used. In particular, as described in the above item 6, it is preferable that the gradation is relatively soft and has a wide latitude. Such gradation is usually achieved by adjusting the sensitivity of a plurality of silver halide emulsions having different sensitivities, and by adjusting the coating amount of the silver halide emulsion or coupler. Further, in order to realize this gradation, Japanese Patent Laid-Open Publication No.
As disclosed in JP-A-4-93941 and JP-A-4-40446, at least two kinds of monodispersed silver halide emulsions having different average grain sizes are used in the same photosensitive layer.
Alternatively, it is preferably contained in all of the layers having the same color sensitivity. Similarly, to achieve this gradation, a method of mixing gradations by mixing several emulsions of the same grain size having different rhodium contents as disclosed in U.S. Pat. No. 4,301,242. Are also preferably used. Also, where
Other than rhodium, desensitizers described in Japanese Patent Application No. 8-8082, for example, metal ions of the seventh, eighth, and ninth groups of the fourth, fifth, and sixth cycles and prevention of fogging Agent,
Stabilizers, desensitizing dyes and the like can also be preferably used.

Preferably, the minimum density of the input color negative photosensitive material in the image after the development processing, that is, the density of the unexposed portion is 0.2 or less. More preferably, it is 0.1 or less. The image density after the development processing is measured by Macbeth densitometer status M. The density of the unexposed part is determined by coloring the support,
It is caused by colored couplers for masking, fogging by silver halide emulsions and dyes added for various purposes. In particular, when a color negative is photoelectrically read by a CCD area sensor, if the density of the unexposed portion is high, the S / N ratio of the obtained signal is deteriorated, and the quality of the finally obtained reproduced image may be deteriorated. It was revealed. This is the same for any of yellow, magenta, and cyan, but it has been found that the influence on the S / N ratio is particularly large when reading through a yellow image, that is, through a blue filter. Therefore, it can be said that the lower the minimum density of yellow, the more preferable.

Further, the gradations γR, γG, and γB of the input color light-sensitive material in the standard white light source exposure are all set to 0.
The color negative is preferably 35 or more and 0.90 or less. More preferably, it is 0.40 or more and 0.80 or less.
The gradient in the standard white light source is obtained as follows. First, when a standard white light source, for example, the light-sensitive material is a daylight-type light-sensitive material, wedge-exposure is performed on the undeveloped light-sensitive material for input with a light source having an energy distribution of 5,500 ° K of black body radiation, and a color negative is applied. Standard processing C4 for film
After performing the development processing according to 1, each about 483 nm,
Density is measured through red, green, and blue filters having transmission maxima at 547 nm and 689 nm, and the logarithm of the exposure is plotted on the horizontal axis and the fog is plotted on a grab that gives density on the vertical axis. The values giving a density of 0.8 and 1.0 are plotted, and these points are linearly approximated by the least squares method.
For the angle θ from the horizontal axis, tan θ is defined as γR, γ
G and γB. Further, for a photosensitive material that is not a daylight type (for example, a tungsten type photosensitive material), the gradation is obtained in the same manner as described above except that exposure is performed using a light source having an energy distribution of black body radiation of 3200 ° K.

When reading an image using a scanner,
Pressure fog on the image has a very significant effect on the final reproduced image. In particular, knick-shaped fogging that occurs when the film is folded before processing, and scratches and pressure fogging that occur during handling in laboratory equipment such as cameras, splicers, and processing equipment sometimes occur. It has been found that the damage to the final image is large. Various methods have been conventionally used to reduce this effect as much as possible, but it has been difficult to say that a sufficient effect has been obtained for an image reproduction system using a digital photo printer. Therefore, as a result of various studies, it was found that an effect was obtained when the amount of silver halide used was reduced to 3 g / m ² or less in terms of the coated silver amount.

Next, the tabular silver halide emulsion grains used in the input color photographic light-sensitive material will be described. Tabular silver halide emulsion grains (hereinafter referred to as "tabular grains")

When the input color photographic light-sensitive material is a color reversal light-sensitive material in particular, the tabular grains are preferably monodisperse having a coefficient of variation in particle size distribution of 20% or less. The variation coefficient referred to here is a value obtained by multiplying 100 by a value obtained by dividing the variation (standard deviation) of the projected area of the tabular grain by the circle equivalent diameter by the average value of the projected area of the average grain by the circle equivalent diameter. is there.

Among such silver halides, those having a silver bromide localized phase on the surface of silver chloride grains are particularly preferable since high sensitivity can be obtained and photographic performance can be stabilized. The silver halide emulsion contained in at least one photosensitive silver halide emulsion layer has a coefficient of variation of grain size distribution (standard deviation of grain size distribution divided by average grain size) of 15% or less. Preferably, a monodispersed emulsion of 10% or less is more preferred. It is preferable to use two or more of the above monodispersed emulsions in the same layer for the purpose of obtaining a wide latitude. At this time, the monodispersed emulsions preferably differ in average grain size by 15% or more, more preferably differ by 20 to 60%, and particularly preferably differ by 25 to 50%.

In order to make the image reproduction system of the present invention compact and inexpensive, it is preferable to use a second harmonic generation light source (SHG) combining a semiconductor laser or a solid-state laser with a nonlinear optical crystal. Particularly, in order to design an apparatus that is compact, inexpensive, and has a long life and high stability, it is preferable to use a semiconductor laser, and it is preferable to use a semiconductor laser as at least one of the exposure light sources.

When using such a scanning exposure light source,
The maximum wavelength of the spectral sensitivity of the output color photosensitive material can be arbitrarily set depending on the wavelength of the scanning exposure light source to be used. In a solid-state laser using a semiconductor laser as an excitation light source or an SHG light source obtained by combining a semiconductor laser and a nonlinear optical crystal, the laser oscillation wavelength can be halved, so that blue light and green light can be obtained. Therefore, the spectral sensitivity maximum of the photosensitive material can be provided in the usual three wavelength ranges of blue, green and red.

In particular, the activator treatment method is a preferred method from the viewpoint of environmental preservation because the processing solution does not contain a color developing agent, so that the treatment solution can be easily managed and handled, and the load of waste liquid treatment is small. In the activator processing method, a photosensitive material containing a color developing agent or its precursor is used. For example, Japanese Patent Application Nos. 7-63572 and 7-334.

An image forming method using an activator solution is preferably used.

Although desilvering is usually performed after the activator processing, desilvering processing is not required in the image amplification processing using a low-silver amount photosensitive material. Therefore, after the activator processing, washing or stabilization processing is performed. Simple processing is preferred. The processing materials and methods of the activator solution, desilvering solution, washing and stabilizing solution which can be used in the present invention are described in detail in Japanese Patent Application No. Hei.

A first frame memory unit 51, a second frame memory unit 52, and a third frame memory unit 53 for storing are provided. Here, a first line buffer 50a and a second line buffer
50b is configured to store the odd-numbered pixel data of each line of the image data in one line buffer and the even-numbered pixel data in the other line buffer alternately.

In the present embodiment, first, the first reading (hereinafter referred to as the first reading) by the image reading apparatus 1 is performed on one frame of a color image recorded on the film F or one color image recorded on one color print P. , Pre-reading), and conversion of the read image into digital image data. At this time, based on the image data obtained by the pre-reading, the image processing device 5 sets image reading conditions for the second reading (hereinafter, referred to as main reading) to be performed next. Then, based on the set reading conditions, reading of the color image, that is, main reading, is executed again, thereby generating digital image data to be subjected to image processing for reproduction. To perform such processing, the image processing device 5 stores the image data obtained by the pre-reading in the first frame memory unit 51, and stores the image data obtained by the main reading in the second frame memory unit 52, The third frame memory unit 53 is configured to store the information.

Before describing the other components shown in FIGS. 5 and 6, these frame memory units will be described in detail. FIG. 7 is a block diagram showing details of the first frame memory unit 51, the second frame memory unit 52, and the third frame memory unit 53. As shown in FIG. 7, the image processing apparatus 5 processes the image data generated by reading the color image by using a first frame memory unit 51,
The second frame memory unit 52 and the third frame memory unit 53 are R (red), G (green),
R data memory 51R, G data memory 51G, and B data memory 51 for storing image data corresponding to B (blue)
B, R data memory 52R, G data memory 52G and B
A data memory 52B, an R data memory 53R, a G data memory 53G and a B data memory 53B are provided.
As described above, the first frame memory unit 51
Stores image data obtained by pre-reading,
While the second and third frame memory units 52 store the image data that is actually read and stored, FIG. 7 shows that the image data obtained by prefetching is input from the input bus 63 to the first frame memory unit 51. The image data stored in the second frame memory unit 52 is output to the output bus 64.
The state output to is shown in FIG.

The configuration of the image processing apparatus 5 will be described again with reference to FIGS. The image processing device 5 includes a CPU 60 that controls the entire image processing device 5. C
PU60 is a CPU 26 that controls the transmission type image reading apparatus 10.
(FIG. 3) or CP for controlling the reflection type image reading device 30
U46 (FIG. 4) is communicable with a communication line (not shown) via a communication line (not shown).
It is configured to be able to communicate with U via a communication line (not shown). With this configuration, the CPU 60 changes the image reading conditions for performing the main reading of the color image based on the image data obtained by the pre-reading stored in the first frame memory unit 51, and further reads as necessary. It is possible to change image processing conditions for image processing to be performed on a subsequent image.

That is, based on the image data obtained by the pre-reading, the CPU 60 sets the image reading conditions for the main reading so that the dynamic range of the CCD area sensor 15 or the CCD line sensor 35 can be used efficiently at the time of the main reading. Is determined, and the reading control signal is transmitted to the CPU 26 of the transmission type image reading device 10 or the C of the reflection type image reading device 30.
Output to PU46. At this time, C of the transmission type image reading device 10
When this reading control signal is input, the PU 26 or the CPU 46 of the reflection type image reading device 30 determines the light amount adjusted by the light amount adjusting unit 12 or the light amount adjusting unit 34 and the accumulation time of the CCD area sensor 15 or the CCD line sensor 35. Control. At the same time, based on the obtained image data, the CPU 60 executes a first image processing means and a second image processing unit (to be described later) so that a color image having an optimum density, gradation and color tone can be reproduced on color paper. A control signal for changing an image processing condition such as an image processing parameter by the processing unit is output to the first image processing unit and the second image processing unit as needed. At this time, CP
The image reading conditions or image processing conditions determined by U60 are stored in the memory 66.

When the CPU 60 performs the above control, if the image reading condition or the image processing condition is held by the instruction of the operator, the CPU 60 does not determine the condition based on the pre-read image data as described above. And outputs various control signals based on the held conditions. When the operator sets various conditions using an input device such as a keyboard 69 and further instructs to hold these conditions, these conditions are stored in the memory 66, and thereafter, when the operator instructs to release the holding of these conditions, the The condition stored in the memory 66 becomes invalid. Therefore, CPU 60
In performing the above-described control, first, a condition stored in the memory 66 is referred to. If the condition is stored, the condition is followed.If the condition is not stored, the condition is determined based on the pre-read image data. To determine these conditions.
It is not always necessary to hold such conditions in large units such as image reading conditions or image processing conditions, and more detailed conditions such as storing or referring to the above conditions in the memory 66 when storing the above conditions are used. For example, the setting of the saturation may be maintained, and the sharpness may be set using an automatically determined condition.

The configuration of the image processing apparatus 5 in the range shown in FIG. 5 has been described above. Here, the image data generated in the image reading apparatus 1 is input to the image processing apparatus 5 through the interface 48, and the first The processing performed on the image data from the time when the image data is stored in the third frame memory unit will be described in detail.

As described above, the image data obtained by pre-reading is used exclusively for determining image reading conditions for main reading and image processing conditions in image processing after reading. Therefore, the image data obtained by pre-reading may have a smaller data amount than image data obtained for the purpose of performing image processing for reproduction, that is, image data obtained by main reading. In the present embodiment, as described below,
Based on the image data obtained by the pre-reading, the color image is reproduced on the CRT 68, and by observing the reproduced color image, the operator can set the image processing conditions or apply the conditions to the subsequent reproduction. It is configured to be able to hold as much as possible. Therefore, the amount of image data obtained by prefetching is
It is sufficient that the data amount is sufficient to reproduce a color image on the CRT 68. In the present embodiment, the data amount obtained by pre-reading is reduced and stored in the first frame memory unit 51.

More specifically, in the transmissive image reading apparatus 10, the CCD area sensor 15 transfers only the image data of the odd field or the even field at the time of the prefetch, and in the reflection image reading apparatus 30, Sometimes, the moving speed of the light source 31 and the mirror 32, that is, the sub-scanning speed, is doubled, so that the data amount of the image data to be read becomes half that in the case of the main reading. 1 is configured.

Further, the averaging means 49 of the image processing apparatus 5 adds and averages the values of two adjacent pixel data of the image data sent for each line to obtain one pixel data. Thus, the number of pixel data in each line of the image data is reduced to half. At the time of pre-reading, only one of the odd-line and even-line pixel data of the image data in which the number of pixel data has been reduced by half by the averaging operation means 49 is transferred to the first line buffer 50a and the second line buffer 50a. By alternately transferring the image data to the line buffer 50b, the number of lines of the image data is reduced to one.
/ 2. That is, one of the pixel data of the odd line and the even line is transferred to the first line buffer 50a and the second line buffer 50b, and the other is not transferred to the line buffers 50a and 50b. Decrease by ２. At this time, the odd-numbered pixel data of each line transferred to the line buffers 50a and 50b is stored in one of the first line buffer 50a and the second line buffer 50b, and the even-numbered pixel data of each line is stored in the first line buffer 50a and the second line buffer 50b. The data is stored in the other of the first line buffer 50a and the second line buffer 50b. Therefore, each of the line buffers 50a and 50b stores every other pixel data of the odd line or the even line.

Further, only the image data stored in one of the first line buffer 50a and the second line buffer 50b (that is, only every other pixel data) is stored in the first frame memory unit 51. By
The number of pixel data in each line is further reduced to １ ／. As a result, finally, the number of pixel data of the image data obtained by the prefetching is reduced to 1/16 and stored in the first frame memory unit 51.

At the time of prefetching, as described above,
Since the number of pixel data in the image data is reduced, the second image data for storing the image data obtained by the main reading is stored.
The frame memory unit 52 and the third frame memory unit 53 read a color image of one frame recorded on a film F such as a negative film or a reversal film or a color image recorded on one color print P. Although the first frame memory unit 51 has a capacity capable of storing the obtained image data, the second frame memory unit 52 and the third frame A memory unit much smaller than the memory unit 53 is used.

Next, as described above, an image processing apparatus for performing image processing on the image data stored in the second frame memory unit 52 and the third frame memory unit 53 as a result of the actual reading. 5 will be described.

The image processing apparatus 5 reproduces a color image on color paper with desired density, gradation and color tone from the image data stored in the second frame memory unit 52 and the third frame memory unit 53. Where possible, look-up tables and matrix operations
First to perform image processing such as gradation correction, color conversion, and density conversion

And a second image processing means 62 (FIG. 6) for performing image processing such as gradation correction, color conversion, density conversion, and the like by matrix operation. The outputs of the second frame memory unit 52 and the third frame memory unit 53 are connected to a selector 55,
55, the second frame memory unit 52 and the second
The image data stored in any one of the frame memory units 53 is selectively input to the first image processing means 61.

Color paper used in ordinary minilabs or the like, or special color paper suitable for high-illuminance short-time exposure unique to laser exposure May be used. As the magazine 91, a magazine used in an ordinary minilab, for example, a magazine described in Japanese Patent Application No. 4-317051 is used.

First, the density data stored as digital data is exposed in a pattern as shown in FIG. 11 for each of a plurality of density steps in a single color of each of the three colors cyan, magenta, and yellow, and in gray obtained by superimposing the three colors. After the development, the developed densities are automatically measured using a densitometer. Based on the difference between the target density and the measured density, the table storing the characteristics of the electric signal given to the modulator at the time of exposure is rewritten for the density data to be reproduced. As a result, it is possible to always stably reproduce an image without being affected by changes in the paper used, the device, the environment, and the like. The input device has a calibration function for keeping the characteristics constant independently of absorbing the characteristic fluctuation due to the replacement of the halogen lamp light source or the like in a constant state. As described above, by independently managing the input device and the output device, stable image reproduction can be always performed.

Next, the image processing according to the present invention will be described. Generally, in an image processing system that converts an image into a digital signal by an imaging device and outputs the digital signal, the sharpness of the image is deteriorated due to the limitation of the frequency characteristics of the input and output systems. Therefore, sharpness enhancement processing is performed before output. The sharpness enhancement processing is generally performed by enhancing image data in a high frequency band, such as unsharp mask processing. However, when the sharpness enhancement process is performed, there is a disadvantage that undesired information such as graininess in the same frequency region is also enhanced. For this reason, a method has been adopted in which the conventional sharpness enhancement is performed in a modest degree such that grain deterioration is not noticeable. Also,
In some cases, adaptive sharpness enhancement such as changing the degree of sharpness enhancement according to image information of a specific area is also performed, but the same is true in that the degree of sharpness enhancement cannot be increased much. Sharpness enhancement in the present invention is a revolutionary method that solves these disadvantages. As will be described in detail in the embodiments, a sharpness enhancement is performed while suppressing graininess by the following method (see Japanese Patent Application No. 7-021842). 1. Image separation is performed in the frequency band. Specifically, first,
Divide into low frequency components and high mid frequency components. 2. R, G, and B of the high-mid frequency component obtained in the above 1
Component, which is converted into one channel of the luminance component. 3. The high and medium frequency components including only the luminance information obtained in the above 2 are divided into high frequency components and medium frequency components. 4. The correlation between R, G, and B is obtained from the high-medium-frequency component obtained in 1 above, and a weighting factor for a granular area or an image signal area is obtained. 5. Finally, on the image of the one low-frequency component, the three high-frequency components and the four low-frequency components are subjected to strong / weak processing with reference to the RGB correlation of four, and the sharpness is enhanced while suppressing graininess. Get.

The image processing method will be described in more detail below. Also, an image processing apparatus performs image processing on image data obtained by an image reading device based on image processing conditions set automatically or manually by an image processing device, and reproduces the image data on a recording material by an image output device. In the system, the image processing apparatus includes means for holding the automatically set (auto set up) or manually set image processing conditions, thereby automatically changing the image processing conditions and manually changing the image processing conditions. By doing so, the set image processing conditions can be reused later. This greatly reduces the time required for setting conditions, improves work efficiency, and enables rapid reproduction of a large number of images under optimal image processing conditions. For details of the automatic setting means and the manual setting means, refer to Japanese Patent Application No. 8-15161.
No. When dodging processing is performed when processing photoelectrically read image information, it is preferable to use the method described in Japanese Patent Application No. 7-165965.

Are the frequency components when the gains M and H for multiplying the later-described intermediate and high frequency components distributed are set to 1.0, and the intermediate frequency components R _M , G _M , and B _M
Is intended to refer to the Nyquist frequency f _s / 2 1/3 frequency component as a distribution H _M with a peak near the output at the time of reproducing the processed data as a visible image, the low frequency components R _L , _GL , and _BL refer to components having a peak at 0 frequency and having a distribution _HL, and high-frequency components _RH ,
G _H and B _H are components having a peak at the output Nyquist frequency f _s / 2 and having a distribution H _H. In the present embodiment, the Nyquist frequency is
Nyquist frequency when recording at 300 dpi. Here, in FIG. 14, the sum of the frequency components is 1 at each frequency.

Next, a luminance component is extracted from the decomposed intermediate / high frequency components R _MH , G _MH , and B _MH . Extraction of the luminance component are those intermediate and high frequency components R _MH of the fine scanning data S _F, G _MH, components Y _MH of when converting the B _MH to YIQ provisions represent the luminance component of the data. Here, the conversion to the YIQ regulation is given by the following equation

[0075]

(Equation 2)

The above is performed.

The component I, which is a color component converted to the YIQ definition
For _MH and component Q _MH are those containing a roughness of color due to the film graininess, wherein the component I _MH and component Q _MH suppress roughness of color due to the film graininess at zero. Here, components I _MH and component Q _MH a color component in the case of ordinary images taken of an object that most no component has been found empirically. Therefore, the component I _MH and the component Q _MH are regarded as color roughness caused by the granularity of the film and are set to 0, whereby a good reproduced image in which the roughness is suppressed can be obtained.

Next, the component Y _MH is subjected to a filtering process by a 5 × 5 low-pass filter 22 in the gain processing section 21 as described below to obtain an intermediate frequency component Y _M of the component Y _MH .

[0079]

(Equation 3)

[0080] obtaining a high-frequency component Y _H of the components Y _MH by further subtracting the intermediate frequency components Y _M of component Y _MH.

Next, the gain M and the gain H obtained by the above-described auto-setup operation means 10 are multiplied by the components Y _M and Y _H , respectively, as shown in the following equation (1), and the processed components Y _M ′ and Y _H ′ is obtained, and the processed components Y _M ′ and Y _H ′ are combined to obtain a component Y _MH ′.

Y _MH ′ = gain M × Y _M + gain H × Y _H (1) (Y _M ′ = gain M × Y _M , Y _H ′ = gain H × Y _H ) where gain M and gain H is set in the auto setup calculation means 10 so that the gain M <the gain H. That is, roughness of the luminance component based on the film graininess is because it contains a relatively large amount to an intermediate frequency component, by setting a relatively low gain of the components Y _M, is capable of suppressing the graininess. Also, since the sharpness of the image depends on the higher frequency components of the luminance component, by relatively increasing the gain H of the high frequency components Y _H of the luminance component, which can be emphasized sharpness of processed image It is.

Here, in the auto setup calculation means 10, for example, when the color image 4 is under negative, the roughness caused by the film graininess is conspicuous, and
When the gradation is set to improve the gradation characteristics, the image becomes very poor in graininess, and therefore, the gain M is set to a considerably low value. And thereby, granularity can be suppressed strongly. Further, the optimum gain M and gain H are set depending on the print size. Further, as described above, when the user selects a desired menu from several sharpness enhancement processing menus, the gain M and the gain H according to the menu are stored as a table, and the menu is stored according to the menu selection. It is preferable that the optimum gain M and gain H can be selected in such a manner. This makes it possible to perform processing for each image or according to the user's preference.

The thus obtained component Y _MH '
The low frequency components R _L of the fine scanning data S _F described above, G _L, B _L and synthesizing the processed signals R ', G',
B 'is obtained. At this time, the above-mentioned component I _MH and component Q _MH
Is set to 0, the processed luminance component Y _MH ′
Is inversely converted to correspond to RGB data, RGB3
All the two data have the same value as the component Y _MH '. Therefore, even if the processed luminance component Y _MH ′ is not inversely transformed, the result of the synthesis is the same as the result of the inverse transformation. Therefore,
In order to simplify the processing, the processed luminance component Y _MH ′ is synthesized without being inverted.

Thereafter, the processed signals R ', G', B 'are input to the reproducing means 3 and reproduced by the printer 15 on the recording material 16 as a visible image.

In the image reproduced in this manner, the color components of the middle and high frequency components of the data including the roughness caused by the film grain are set to 0, and further, the luminance components of the middle and high frequency components are Since the gain _M of the intermediate frequency component Y _M is suppressed and the gain _H of the high frequency component Y _H is emphasized, an image is obtained in which sharpness is enhanced and roughness due to film graininess is suppressed.

Next, a second embodiment of the present invention will be described.

FIG. 15 is a block diagram for explaining details of the processing performed in the processing means 13 of the image processing apparatus according to the second embodiment of the present invention. As shown in FIG. 15, the processing means 13 of the image processing apparatus according to the second embodiment of the present invention
Is provided with a specific color extraction gain calculating means 23. In the specific color extraction gain calculating means 23, a specific color portion is extracted from the color image 4, and a gain M for multiplying the above-mentioned luminance component _YMH only for this portion is extracted.
And the value of the gain H are changed. The specific color extraction gain calculating means 23 performs the processing shown in FIG. That is, low frequency components of the fine scanning data _{S F R L, G L,} B performs processing for converting the YIQ defined for _L, more aforementioned five components by performing a filtering process by the low-pass filter 22 × 5 Y _L to obtain a low frequency component of the component I _L and component Q _L. here,
The components Y _L , I _L, and Q _{L of the} low frequency components R _L , G _L , and B _L are filtered by the low-pass filter for the following reason. That is, the low frequency components R _L, G _L, components B _L Y _L, the components I
Frequency characteristics of the _L and component Q _L, as shown in FIG. 6, component I _L and component Q _L is primarily a signal to a lower frequency band, component Y _L are those having components up to a high frequency band. And the high frequency band of the component Y _L (the shaded portion in FIG. 17)
Contains a relatively large amount of noise components. Therefore, in order to improve the accuracy of color extraction performed later by removing the noise component, filtering is performed by the low-pass filter 22 to remove the noise.

[0089] Then this way extracted components Y _L, I _L, of Q _L, the detection of a specific color using the components I _L and the component Q _L. In addition. In this embodiment, it is assumed that flesh color is detected. The horizontal axis The skin color detection, respectively the components Q _L and component I _L is the color components as shown in FIG. 7, in a QI plane on the vertical axis a predetermined range around the color to be hue angle theta (in Fig. A pixel having a signal value of (shaded area) and a signal value larger than a predetermined threshold value is detected as a skin color area. Here, the threshold value processing is mainly performed on a human face when skin color detection is performed, and the signal value of this part is considerably larger than other areas. Therefore, threshold processing is performed in order to prevent other skin-ish parts from being extracted and to easily detect the face area.

After the flesh color area is detected in this manner, the gain M and the gain H for the flesh color area are determined.
Is changed. In other words, as shown in FIG. 19 (a), a weighting function W (θ) for emphasizing the hue angle portion corresponding to the hatched portion shown in FIG. 18 is determined, and FIG. The gain M and the gain H are changed as shown in FIG. The gain M (θ) and the gain H (θ) at the hue angle θ are calculated by the following equation (2).
Shown in

Gain M (θ) = Gain Mh−W (θ) · (Gain Mh−Gain Ml) Gain H (θ) = Gain Hh−W (θ) · (Gain Hh−Gain Hl) (2) , Gain Mh, gain Hh: maximum value of gains M and H gain Ml, gain Hl: minimum value of gains M and H According to equation (2), as shown in FIG. The value of H is set smaller than the gains M and H of the other color regions.

After obtaining the gain M (θ) and the gain H (θ) in this manner, based on the gain M (θ) and the gain H (θ), the intermediate frequency component Y _M of the luminance component Y _MH described above is obtained. and multiplied by a gain in the high frequency components Y _H.
Then, the intermediate frequency component Y _M ′ multiplied by the gain and the high frequency component Y _H ′ are combined to obtain a processed luminance component Y _MH ′,
Further, the processed image signals R ', G', and B 'are obtained by combining the low-frequency components R _L , G _L , and B _L.

As described above, by detecting a specific color region from an image and changing the gain by which the specific color region is multiplied, it is possible to further suppress the roughness of a skin color region in which the roughness due to the film graininess is a concern. A higher quality reproduced image can be obtained.

In the above-described second embodiment of the present invention, the detection of a flesh-color area has been described. May be performed. In addition, the sky blue is a portion indicated by a shaded broken line in FIG. 18 on the QI plane.

Next, a third embodiment of the image processing apparatus according to the present invention will be described.

FIG. 20 is a block diagram for explaining details of the processing performed in the processing means 13 of the image processing apparatus according to the third embodiment of the present invention. As shown in FIG. 20, the processing means 13 of the image processing apparatus according to the third embodiment of the present invention
Is provided with a correlation value calculating means 30 for calculating a correlation value between the three colors RGB. In this correlation value calculation means 30, the intermediate and high frequency components of the fine scanning data S _F R _MH, G _MH, correlation values between each of the colors B _MH epsilon
Is calculated, and the value of the gain M is obtained by referring to the look-up table 31 based on the calculated ε. Hereinafter, calculation of the correlation value ε will be described in detail.

[0097] In general, a random variable X, the cross-correlation of Y _{is, E {(X-X m} ) · (Y-Y m)} X m, Y m: expressed as mean value, as shown in FIG. 21 3 Can be classified as follows. That is, as shown in FIG. 10 (a), E {( X-X m) · (Y-Y m)} = no correlation with X and Y in the case of 0, in FIG. 21 (b) As shown, E {(X−X _m ) · (Y−Y _m )}> 0, and when the absolute value is large, the correlation between X and Y is large, and as shown in FIG. In addition, E {(X−X _m ) · (Y−Y _m )} <0, and when the absolute value is large, the correlation between X and Y is large.

Assuming that the correlation values have such a relationship, the correlation values ε _RG , ε _GB , and ε _BR between the colors of the intermediate and high frequency components R _MH , G _MH , and B _MH are calculated by the following equation ( 3) Determined by.

[0099]

(Equation 4)

Where ε _RG : correlation value between _RG ε _GB : correlation value between _GB ε _BR : correlation value between _BR m: size of mask for finding correlation value (m = 1,
(About 2, 3, 4) Note that here, the intermediate and high frequency components R _MH , G _MH , and B _MH
When the average value is obtained, the average value becomes substantially 0, so that subtraction of the average value from each signal value can be omitted.

Here, the correlation value between the colors is obtained as follows. That is, as shown in FIG. 22, when the correlation value between the component R _MH and the component G _MH is obtained, the flat portion 33 having a large amount of noise due to the granularity of the film shows a random signal for each component. It is almost 0. Also, the edge part
In the case of 34, since a signal appears similarly for each component, the correlation value becomes a large value. Further, when the correlation value is negative as shown in FIG. 21 (c) described above, it is a correlation between the signals as shown in FIG. 23, and cannot be at the edge of the image signal. In this case, it is regarded as 0. Therefore, when each of the correlation values ε _RG , ε _GB , and ε _BR is smaller than a predetermined threshold value, the portion where the correlation value is obtained is a flat portion with a lot of noise due to granularity, and the correlation value is If the correlation value is larger than the predetermined threshold value, the part where the correlation value is obtained can be regarded as an edge part.

Next, in the above equation (3), m = 1
The details of the calculation of the correlation values ε _RG , ε _GB , and ε _{BR and} the calculation of the gain in the case of will be described. As shown in FIG. 24, first, correlation values of the components R _MH , G _MH , and B _MH are obtained.
In FIG. 24, referring to the table 36, the correlation value is set to 0 when the correlation values ε _RG , ε _GB , and ε _BR become negative. Intermediate and high frequency components R _MH, G _MH, components R _MH of B _MH, above formulas for the component G _MH, and component B _MH in (3) m
The correlation value between each signal when = 1 is given by the following equation:
Required by (4).

[0103]

(Equation 5)

Then, the correlation values ε _RG , ε _GB , and ε _BR obtained by the equation (4) are added by the following equation (5).

Ε = ε _RG + ε _GB + ε _BR (5) Then, from ε obtained in this way, FIG.
The value of the gain M according to the correlation value of each pixel is obtained with reference to a look-up table as shown in FIG. That is,
When the correlation value ε is smaller than a predetermined threshold value Th, the value of the gain M is reduced, and when the correlation value ε is larger than the threshold value Th, the value of the gain M is increased. Then, the gain M obtained in this manner is converted to the intermediate frequency component Y _M of the luminance component Y _MH of the above-described intermediate / high frequency components R _MH , G _MH , and B _MH.
And the intermediate frequency component Y multiplied by the gain M
_M and synthesize 'the gain H are high frequency components Y _H, which is multiplied by', and the low frequency components R _L of the fine scanning data S _F, G _L, B _L and synthesizing the processed image signals R ',
G 'and B' are obtained.

As described above, the correlation value ε of each color R, G, B between signals is calculated, and the value of the gain M is changed in accordance with the correlation value ε. Since the correlation value ε is small, the gain M is further reduced, and the roughness is further suppressed, so that a higher quality reproduced image can be obtained.

Hereinafter, a method of changing the gain according to the correlation value according to the present embodiment and a method of changing the gain according to the variance described in Japanese Patent Publication No. 3-502975 will be described in comparison.

The method described in Japanese Patent Application Laid-Open No. Hei 3-502975 obtains a local variance value plotted against the number of appearances of a flat portion, a texture, and an edge portion where there is much noise due to the film grain of an image, and obtains a blur mask. Processing equation S '= S
This is a method of setting a coefficient K in org + K · (Sorg−Sus) as a function of the local variance value. That is, in a normal image, local variance values of a flat portion, a texture, and an edge portion are as shown in FIG. Here, focusing only on the local variance value σ _N of the image signal of the flat portion, the values of the variances σ _Na , σ _Nb , and σ _Nc change according to the granularity of the film as shown in FIG. . That is, the peak value of the variance σ increases as the film grain size increases (in FIG. 27, σ _Na
Is the dispersion of a low-sensitivity film with small film granularity, σ _Nb is the dispersion of a medium-sensitivity film with medium film granularity, and σ _Nc is the dispersion of a high-sensitivity film with large film granularity. As described above, the variance value of the image signal changes due to the film granularity, and furthermore, depending on the film granularity, it is difficult to separate the dispersion of the flat portion from the dispersion of the texture, so that the gain setting becomes very complicated. .

On the other hand, the distribution of the correlation values is shown in FIG.
Is similar to the distribution of the variance
Value σ_NIs always 0 regardless of the film granularity.
That is, as shown in FIG.

In the third embodiment of the present invention described above, the gains M and H are changed based on the correlation value ε of the sum of the correlation values ε _RG , ε _GB and ε _BR between the colors. However, the correlation values ε _RG , ε _GB ,
The gains M and H may be changed based on any one or the sum of two correlation values of ε _BR . Thereby, the calculation of the correlation value can be simplified, and the scale of the processing device can be reduced.

However, if the gain processing is performed based only on the luminance component after the conversion to the YIQ basis, the roughness caused by the film graininess can be largely suppressed.

Conventional color reversal light-sensitive materials having a red-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer, a blue-sensitive silver halide emulsion layer and a non-light-sensitive intermediate layer can be used. It is desirable that at least one, preferably two, non-photosensitive intermediate layers exist between the color-sensitive layers. Further, each color-sensitive layer is preferably composed of three or more layers having different sensitivities. Hereinafter, the input photosensitive material used in the present invention will be described in detail. The photographic constituent layer of the light-sensitive material may contain a coupler, a DIR compound, a color mixing inhibitor and the like described below. The plurality of silver halide emulsion layers constituting each unit photosensitive layer are DE 1,121,470 or GB 923,045

Also, as described in JP-B-49-15495, the upper layer is the most sensitive silver halide emulsion layer, the middle layer is the silver halide emulsion layer of lower sensitivity, and the lower layer is more sensitive than the middle layer. An example is an arrangement in which a low silver halide emulsion layer is arranged and three layers of different sensitivities are sequentially reduced in sensitivity toward a support. Even when such three layers having different sensitivities are used, as described in JP-A-59-202464, the medium-sensitive emulsion layer / high The layers may be arranged in the order of a light-sensitive emulsion layer / a light-sensitive emulsion layer. In addition, a high-speed emulsion layer / low-speed emulsion layer / medium-speed emulsion layer, or a low-speed emulsion layer / medium-speed emulsion layer / high-speed emulsion layer may be arranged in this order.

The crystal structure may be uniform, the inside and the outside may be composed of different halogen compositions, or may have a layered structure. Silver halides having different compositions may be joined by epitaxial joining, or may be joined to a compound other than silver halide, such as, for example, silver rhodanate or lead oxide. Also, a mixture of particles of various crystal forms may be used. The above emulsion may be either a surface latent image type in which a latent image is mainly formed on the surface, an internal latent image type in which the latent image is formed inside the grains, or a type having a latent image on both the surface and the inside. It is necessary to be. Among the internal latent image types, core / shell type internal latent image type emulsions described in JP-A-63-264740 may be used.
This preparation method is described in JP-A-59-133542. The thickness of the shell of this emulsion varies depending on the development process, etc.

The term "silver halide particles having a fogged interior or surface" refers to silver halide grains that can be uniformly (non-imagewise) developed regardless of unexposed portions and exposed portions of the photosensitive material. ,
The preparation method is described in US Pat. No. 4,626,498, JP-A-59-214852. The silver halide forming the internal nucleus of the core / shell type silver halide grain having the inside of the grain fogged may have a different halogen composition. As the silver halide having the inside or surface of the grain fogged, any of silver chloride, silver chlorobromide, silver iodobromide and silver chloroiodobromide can be used.
