Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a print, in which a main part such as a person's face is cut off halfway, for example, an original image such as an image photographed on a film. If so, it relates to a printing system that relieves the main part from being included in the print properly.

[0002]

2. Description of the Related Art Conventionally, printing of an image photographed on a photographic film (hereinafter referred to as a film) such as a negative film or a reversal film onto a photosensitive material is performed by directly exposing the photosensitive material to a surface by projecting an image of the film. It has been done by exposure. On the other hand, a digital print system that photoelectrically reads, for example, image information photographed on a film, converts this into digital data, performs various image processings, and digitally exposes a photosensitive material has been put into practical use. Have been.

The above-described digital print system basically controls and manages the operations of an image reading apparatus such as a scanner for reading image data recorded on an original such as a transparent original or a reflective original, and the entire digital print system. An image processing device that performs various image processing on input image data,
In addition, an image recording apparatus including a printer for digitally exposing the photosensitive material in accordance with the image data after image processing, a processor for developing the exposed photosensitive material, and the like are provided.

In a digital print system, a document image is first read by a scanner. The read image data is converted into digital data, and in the image processing device,
Image processing conditions (exposure conditions) are determined from the image data, and various image processes are performed. In the printer, the photosensitive material is scanned and exposed according to the image data after the image processing, and a latent image is recorded. Then, the processor performs development processing according to the photosensitive material, and reproduces the image photographed on the film. This is the finished print.

According to the digital print system, the exposure time is short, and quick exposure can be performed.
In addition, since the image information of the finished print can be stored on a recording medium such as a magneto-optical disk, it is not necessary to re-read the film, for example, and operations such as additional printing are quick and easy. In addition, there is an advantage that editing such as image synthesis and image division, image processing such as color / density adjustment, etc. can be freely performed, and a finished print subjected to editing and image processing can be output freely according to the application. .

When looking at the finished print, especially in a panoramic print or the like, a main part such as the face of the subject may be cut off in the middle. This may be caused by, for example, a shooting error by the photographer, or a case where the scene viewed through the viewfinder of the camera is not correctly exposed to the film. In such a case, a compromise is conventionally made by determining that the photographing error has occurred. However, in practice, the main part is often properly photographed on the film.

For example, in the case of panoramic photographing, only the viewfinder itself is set to a panoramic size, or depending on the camera, only a part of the viewfinder is designated as a panoramic size, and the photographing size on film is limited. It doesn't change, so most of the film, including the main parts, is properly shot.

[0008]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the prior art. In the finished print, even if the main part is cut off halfway, the object is photographed on a film, for example.

It extends in the main scanning direction corresponding to the slit 40 a of the mask 40. The projection light of the film F is separated into three primary colors of RGB by the image sensor 34 and read photoelectrically.

In the scanner 12, the amount of the reading light emitted from the light source 22 is adjusted by a variable aperture 24,
After being uniformly diffused in the plane direction of the film F by the diffusion box 28, the light is incident on the film F transported in the sub-scanning direction by the transport roller pairs 41a and 41b through the slit 40a of the mask 40 in the carrier 30. As a result, the film F is two-dimensionally slit-scanned by the slit 40a extending in the main scanning direction.

When the reading light passes through the film F, the projection light carrying the image photographed on the film F becomes
An image is formed on the light receiving surface of the image sensor 34 by the image forming lens 32, separated into three primary colors of RGB by the image sensor 34, and read photoelectrically. Image sensor 3

The scanner 12 first performs a pre-scan for reading an image photographed on the film F at a low resolution, and then performs a main scan for reading at a high resolution. Although described in detail later, in the image processing device 14,
Image processing conditions are set from the image data obtained by the pre-scan, and the image data of the main scan is subjected to image processing using the image processing conditions. Here, the difference between the pre-scan and the main scan is only that the resolution of the read image is different.

As shown in FIG. 2A, the magnetic heads 42 and 42 for reading information recorded on the magnetic recording medium of the APS film F and recording necessary information are provided on the carrier 30. Are located.

FIG. 3 is a schematic view showing an embodiment of the APS film. As shown in FIG. 3, the APS film F has a predetermined area on the leading end side of the top frame G1 in the drawing direction (the direction of arrow A in the drawing) from the cartridge 46, an area corresponding to each frame G, and A transparent magnetic recording medium S extending in the longitudinal direction (sub-scanning direction) is formed near the both ends in the width direction (main scanning direction) of a predetermined area further rearward than the last frame (not shown). ing.

On the magnetic recording medium S1 at the front (rear) end of the film F, information on the entire film F, such as the cartridge ID, film type, sensitivity, and development date, is magnetically recorded. In S2, information at the time of shooting for each frame, such as shooting date and time, presence or absence of strobe light emission at the time of shooting, title, shooting size or shooting format, and positional information of main parts, are recorded. Basically, camera-related information is recorded on one side in the width direction of the magnetic recording medium S, and laboratory-related information is recorded on the other side.

In the case of a new photographic system, the information at the time of photographing is magnetically recorded on the magnetic recording medium S of the film F, optically recorded at a predetermined position on the film F, or mounted on the cartridge 46. It is preferable to electrically record the data in an IC memory (not shown). In the case of a conventional photographic system, it is preferable to optically record information at the time of shooting at a predetermined position on the film. When an image file is used as the original image data, it is preferable to record information at the time of shooting in the image file.

The magnetic head 42 reads information recorded on the magnetic recording medium S2 of a frame to be read and supplies the information to the image processing device 14. In addition, various kinds of information as described above are written to and read from the magnetic recording medium S of the film F by, for example, a camera, a developing device of the film F, the carrier 30, and the like. Reference numeral P in the figure is a perforation hole for transporting (sending and rewinding) the film F at the time of photographing, for example.

Furthermore, not only APS film but also ordinary 135 size film, DX code, extended DX code,
A bar code such as an FNS code is recorded. A code reader 44 for optically reading these bar codes is arranged between the magnetic head 42 and the mask 40 of the carrier 30. The code reader 44
Are arranged not only on the APS carrier 30 but also on a normal carrier.

In the printing system of the present invention, the scanner is not limited to the slit scanning type, but may be a type that uses surface exposure, which reads the entire surface of one frame image at a time. In this case, for example, an area CCD sensor is used, and a means for inserting each of the RGB color filters is provided between the light source and the film F.
Reading an image by the sensor is sequentially performed by each of the RGB color filters, and the image photographed on the film is sequentially decomposed into three primary colors.

In addition to scanners that read reflective originals, imaging devices such as digital still cameras and digital video cameras, computer communications such as the Internet and local area networks, MO
A recording medium such as a disc (medium recording / reading means) is exemplified.

As described above, the digital signal output from the scanner 12 is output to the image processing device 14 (hereinafter, referred to as the processing device 14). Here, FIG. 4 shows a block diagram of an embodiment of the processing device 14. The illustrated processing apparatus 14 includes a data processing unit 48, a Log converter 50, a prescan (frame) memory 52, a main scan (frame) memory 54, a prescan processing unit 56, a main scan processing unit 58, and condition setting. It has a part 60.

For the sake of simplicity, FIG. 4 shows only parts related to image processing. However, the processing unit 14 includes an input unit 18 and a display unit 20 such as a personal computer. And a control unit that controls and manages the entire print system 10 including the processing device 14 via the printer.

Each of the RGB digital signals supplied from the scanner 12 to the processing device 14 is first processed by a data processing unit 48.
, Predetermined data processing such as dark time correction, defective pixel correction, shading correction, etc., is performed, and is log-converted by the Log converter 50 into density data. The data is stored in the scan memory 52, and in the case of a main scan, is stored in the main scan memory 54 as main scan data.

The pre-scan data stored in the pre-scan memory 52 is sent to a pre-scan processing section 56,
The main scan data stored in the main scan memory 54 is read out by the main scan processing unit 58 and processed.
In the processing device 14, the pre-scan processing unit 56 has an image data processing unit 62 and an image data conversion unit 64, and the main scan processing unit 58 has an image data processing unit 66 and an image data conversion unit 68.

Here, the processing unit 62 of the pre-scan processing unit 56 and the processing unit 66 of the main scan processing unit 58
A part that performs predetermined image processing on an image (image data) read by the scanner 12 in accordance with processing conditions set by a condition setting unit 60 described later.
In 6, the same processing is basically performed except that the resolution is different. The image processing in the two processing units 62 and 66 is not particularly limited, and various known image processing can be applied.

The image processing includes, for example, gray balance adjustment, gradation correction, density (brightness) adjustment, and matrix (MTX) using an LUT (look-up table).
Using a low-pass filter, an adder, an LUT, an MTX, or the like, or using an averaging process, an interpolation operation, or the like in which these are appropriately combined. Examples include electronic scaling processing, dodging processing (compression / expansion of density dynamic range), and sharpness (sharpening) processing.

On the other hand, the image data conversion unit 64
The image data processed by the display unit 2 is thinned out as necessary, for example, by using a 3D (three-dimensional) -LUT or the like, and
The image data is converted into image data for display according to 0 and supplied to the display unit 20. Similarly, the image data conversion unit 68 includes a processing unit 66
Is converted into image data for image recording by the image recording device 16 using a 3D-LUT or the like and supplied to the image recording device 16.

Subsequently, in the processing device 14, the condition setting section 60 sets various processing conditions in the pre-scan processing section 56 and the main scan processing section 58, read conditions of the main scan, and the like. , A key correction unit 74 and a parameter integration unit 76. In the condition setting unit 60, first, the setup unit 72 includes a main part extraction unit (hereinafter, referred to as an extraction unit) 72A and a setting unit 7
2B.

In the setup section 72, first, the extraction section 72A executes various main portion extraction processing on the pre-scan data image, and extracts the main face, eyes, hair, etc. of a person from the pre-scan data image. Based on the extraction result of the main part and the information at the time of shooting, such as the shooting size or shooting format, it is detected whether or not the main part is cut off in the print size corresponding to the shooting size, for example. If it is cut, change the print size or print area so that it does not cut.

For example, in the case of APS, as shown in FIG. 5, three photographing sizes of C type, H type and P type are prepared. At the time of photographing, the image is photographed on the entire surface of the film, that is, always in the H type, but at the time of printing, only the image in the photographing size area is printed. The photographer can freely determine the photographing size at the time of photographing, and the photographing information such as the photographing size is recorded on the magnetic recording medium S2 of the film F of the APS shown in FIG.

As shown in FIG. 6, in the case of APS, the print system 10 of the present invention reads magnetic information recorded on a film magnetic recording medium such as the magnetic head 42 shown in FIG. 2A. Means, for example, means for determining information at the time of shooting such as a shooting size or a shooting format, main part extracting means for extracting a main part such as a face area of a subject from an original image, and extraction of information and main part at the time of shooting There is a change means for changing the print size or print area of the original image based on the result.

In the print system 10 of the present invention, FIG.
As shown in FIG. 1, first, information at the time of shooting, such as a shooting size or a shooting format, is read from magnetic data recorded on the magnetic recording medium S of the film F, and the shooting size, that is, the print size is C type, H type or P type. After determining which of the above, read the image data to extract the main part such as the face area, etc., based on this extraction result, if the face is cut off at the determined shooting size, change the print size or print area And print.

For example, as shown in FIG. 7A, when the photographing size is of the P type, and based on the result of the extraction, it is detected that the P size causes an out of face, the occurrence of this out of face is determined. In order to prevent this, in the present invention, as shown in FIG. 7B, the size of the finished print is not changed to the C type or H type, or the size of the finished print is not changed. ),
The print area is shifted upward in the figure.

Although not shown in FIG. 6,
After changing the print size or the print area, it is preferable to provide a determination unit for determining whether or not the main part such as the face fits within the print size by the change. In this case, after the print size or print area is changed, if the main part does not fit within the print size properly, the print size or print area may be changed again, or the main part may be fit within the print size. May not be determined.

In an ordinary printing system, an area to be printed in an image photographed on a film is fixedly determined according to, for example, a photographing size. For this reason, in spite of the fact that the main part is properly photographed in the film, the main part may be cut off in the print, but in the present invention, the main part is detected from the image and the main part is detected. Since the print size and the print area are changed so as not to cut the part, failure photographing in which the main part is cut can be reduced as much as possible.

It is to be noted that there are two modes, a photographing size priority (photographing format priority) and a main part extraction result priority, and these modes may be switched and used according to, for example, an order or a use.

In the above embodiment, the case of APS has been described as an example, but the present invention can be applied to a conventional photographic system. In the case of a conventional photographic system, information at the time of photographing, such as a photographing size or a photographing format, is not recorded as magnetic information on the film. Therefore, information at the time of photographing may be optically recorded on the film, or a keyboard may be used. Information at the time of shooting may be separately input from the mouse 18a or the mouse 18b. In the illustrated example, an example of shifting upward is shown. However, the shifting may be performed not only in one-dimensional direction but also in two-dimensional directions such as up, down, left, and right in accordance with the position of the main part.

Although there is no particular limitation on the main part extraction method executed in the present invention, the extraction unit 72A in the illustrated example includes, for example, face extraction by extracting skin color / circle shape, and face extraction / circle shape extraction. Face extraction, face extraction by torso / circle shape extraction, face extraction by eye (internal face structure) / circle shape extraction, face extraction by hair part extraction / circle shape extraction, background extraction. The method for extracting these main parts is described in detail in Japanese Patent Application Laid-Open No. 8-184925 and the like.

For example, in the skin color / circular shape extraction, a face region is extracted by performing skin color extraction and circular shape extraction.
That is, the hue and saturation of each pixel are found from pre-scan data (thinning can be performed if necessary), and a pixel area (skin color area) that can be estimated as a skin color of human skin is extracted. Is generally an elliptical shape, an (elliptical) circular shape presumed to be a human face is extracted from the extracted skin color region, and this is used as a face region candidate.

In the face contour / circle shape extraction, a face region is extracted by performing face contour extraction and circular shape extraction by edge extraction. Similarly, torso / circular shape extraction is torso contour extraction and circular shape extraction by edge extraction, eye / circle shape extraction is human eye extraction and circular shape extraction, and hair / circle shape extraction is edge extraction The extraction of the human hair and the extraction of the circular shape are performed to extract the face region. In addition, background extraction
A background portion other than a person is extracted by using contour extraction to obtain auxiliary information such as face extraction.

In the present invention, for example,

9-101579, 9-138470, 9-
Various known main part extraction methods disclosed in respective publications such as 138471 can also be used.

The extraction section 72A basically performs all of the above-described main part extraction, and extracts a main part such as a face region based on the result.

On the other hand, the setting section 72B prepares a density histogram from the pre-scan data and calculates image features such as average density, highlight (lowest density), shadow (highest density), and reads the main scan. Determine the conditions. The setting unit 72B is a LUT that performs gray balance adjustment, gradation correction, density adjustment, and the like in accordance with the main part of the image extracted by the extraction unit 72A, and further according to an instruction from an operator performed as needed. , An MTX operation formula, calculation of a sharpness correction coefficient, etc.
Further, various image processing conditions in the main scan processing unit 58 are set.

Subsequently, in the condition setting section 60, the key correction section 74 includes keys for adjusting the density (brightness), color, contrast, sharpness, saturation, etc. preset on the keyboard 18a, the mouse 18b, and the like. The amount of adjustment of the image processing condition is calculated in accordance with various instructions and the like input from the input unit 18 of the above, and is supplied to the parameter integration unit 76.

The parameter integrating section 76 includes a setting section 7
2B, and receives the image processing conditions set by the pre-scan processing unit 56 and the main scan processing unit 5.
The image processing condition set for each part is corrected (adjusted) or reset according to the adjustment amount calculated by the key correction unit 74.

Hereinafter, the operation of the printing system 10 will be briefly described. When the start of the print production of the film F is instructed, first, the scanner 12 starts a pre-scan, and the image photographed on the film F is decomposed into RGB, photoelectrically read and converted into a digital signal.
The RGB digital signals output from the scanner 12 are supplied to the processing device 14, subjected to predetermined data processing, and stored in the pre-scan memory 52.

In the case of APS, the magnetic recording medium S
The information at the time of photographing, such as the photographing size, is read out, and a bar code such as a DX code is read by the code reader 44, and necessary information is sent to a predetermined portion. Thereafter, the prescan data is read from the prescan memory 52, and the extraction unit 72A and the setting unit 72B of the setup unit 72 of the condition setting unit 60, and

Here, verification is performed by the operator as necessary. The pre-scan data is subjected to image processing in the processing unit 62, converted into image data for display in the image data conversion unit 64, and converted as a simulation image into the display unit 2.
0 is displayed. The operator sees the image displayed on the display unit 20, confirms (verifies) the processing result, and uses the adjustment keys and the like set on the keyboard 18a as necessary to adjust the color, density, gradation, and the like. To adjust.

The input of this adjustment is supplied to the key correction section 74. The key correction unit 74 calculates the correction amount of the image processing condition according to the adjustment input, and this is calculated by the parameter integration unit 7.

When the operator determines that the image of this frame is proper (OK), the operator instructs the start of printing using the keyboard 18a, the mouse 18b, or the like. As a result, the image processing conditions are determined, the reading conditions for the main scan are set in the scanner 12, and the main scan is started. If the verification is not performed, the image processing conditions are determined when the setting of the image processing conditions in the main scan processing unit 58 by the parameter integration unit 76 is completed, and the main scan is started.
