Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera for forming a high-quality image by performing image processing of a photographed image by the camera using related information for image processing recorded by the camera at the time of photographing or the like. And an image forming system.

[0002]

2. Description of the Related Art Conventionally, printing an image photographed on a photographic film (hereinafter simply referred to as a film) such as a negative film or a reversal film onto a photosensitive material (photographic paper) involves projecting the image of the film onto the photosensitive material. The so-called direct exposure (analog exposure), in which the photosensitive material is exposed on the surface, is the mainstream.
On the other hand, in recent years, a printing apparatus using digital exposure, that is, an image recorded on a film is photoelectrically read, and the read image is converted into a digital signal. 2. Description of the Related Art Digital photo printers have been put to practical use in which a photosensitive material is scanned and exposed with recording light modulated in accordance with the image data to record an image (latent image) and print the image (finished).

[0003] In a digital photo printer, the exposure conditions at the time of printing can be determined by image data processing using an image as digital image data, so that image skipping and crushing caused by backlight, strobe photography, and the like can be corrected, and sharpness can be reduced. By suitably performing (sharpening) processing, correcting color or density feria, etc., it is possible to obtain high-quality prints that cannot be obtained by conventional direct exposure. Further, synthesis of a plurality of images, image division, and synthesis of characters can also be performed by image data processing, and a print that has been freely edited / processed according to the intended use can be output. Moreover,
According to the digital photo printer, not only can an image be output as a print (photo), but also image data can be directly output to a recording medium and used for various purposes other than a photo.

[0004] Such a digital photo printer basically includes a scanner (image reading device) for photoelectrically reading an image recorded on a film, and image data (exposure conditions) for processing the read image and outputting the image. An image input device having an image processing device, a printer (image recording device) for scanning and exposing a photosensitive material in accordance with image data output from the image input device to record a latent image, and an exposed photosensitive material And an image output device having a processor (developing device) that performs a development process on the image to produce a print.

[0005] Incidentally, as a cause of image quality deterioration when an image photographed on a film is reproduced on a print, there is a so-called aberration caused by the lens performance of a camera. For example, even with one lens, R (red) light, G (green) light
Since the refractive index is different between light and B (blue) light, the so-called chromatic aberration of magnification occurs, in which the R, G, and B lights shift the image formation position on the film even at the same position in the scene, and the film is photographed on the film. When an image is reproduced, a color shift occurs in the obtained image. Also, in order to obtain a proper captured image,
A plane perpendicular to the optical axis needs to be imaged correspondingly on the image plane, but with a normal lens, the image plane shifts in the optical axis direction, distorting the formed image, When a so-called distortion is generated and an image photographed on a film is reproduced, the obtained image is distorted. In addition, image quality deterioration is also caused by a decrease in the amount of peripheral light, which causes the image to be darker in the periphery than in the optical axis, depending on the performance of the lens, and a focus blur caused by a difference in focus position in the film surface direction. Is the cause.

[0006] As described above, various methods have been proposed in the past to correct image quality deterioration of a photographed image due to the performance of a lens and obtain a high-quality image (print). For example, Japanese Unexamined Patent Publication No. Hei 6-237376 discloses a method of recording image quality deterioration information, which is specific to a camera body and a lens, which is a cause of deterioration of a photograph, on a photographic film, reads the information at the time of printing, and based on this information, A deteriorated image restoration system that performs a restoration process is disclosed. Also, JP-A-4-3422
No. 41 discloses a peripheral distortion state of a photographing screen based on photographing angle-of-view information and subject distance information, records the peripheral distortion information on a photographic film, and corrects the peripheral distortion using the peripheral distortion information at the time of printing. There is disclosed a camera that does this.

Japanese Patent Application Laid-Open No. 9-281613 discloses a photographic processing apparatus and a photographic processing method in which information on a camera, a lens, and the like is recorded on a photographic film, and the quality of an image is corrected by using this information during printing. Is disclosed. Further, in Japanese Patent Application Laid-Open No. H11-231465, a new barcode is provided in addition to a DX barcode, an extended DX barcode, and the like which are conventionally recorded on a film. A print system is disclosed in which lens characteristic data and the like are recorded on a photographic film, and magnification and chromatic aberration and distortion are corrected using the photographic film to output a high-quality image without color shift and distortion. .

[0008]

However, each of the conventional methods for correcting image quality deterioration uses information (mainly, lens information) indicating the cause of image deterioration recorded on a film at the time of photographing at the camera side. Based on this information, the printing system reads the information, and based on this information, uses the correction information corresponding to the information stored in a database or the like on the system side,
Since the image quality degradation is corrected, every time a new product is released, information on the product must be accumulated, and there is a problem that the amount of information to be stored becomes enormous.

As shown in (b), the correction is set and stored in advance in the image forming system (internal memory 56) as a pattern in which all the corrections are set. In FIG. 6A, for example, in the camera 1-1, two types of wide angle (W1, W2) are used.
2), standard (N), and two types of telephoto (T1, T2) are used as common correction patterns for the vertical and horizontal directions of the screen, and patterns 1 to 5 are respectively set. Selected and specified from inside.
The camera 1-2 is also common in vertical and horizontal directions, and a common correction pattern (pattern 1) is set for two types of wide angles, and a common correction pattern (pattern 4) is also set for two types of telephoto. . Also, the camera 1-3
In each of the three types of focal lengths of the wide angle W, the standard N, and the telephoto T, patterns are set separately in the vertical and horizontal directions.

Further, according to the focal length and the contents of correction,
When selecting and designating correction patterns separately, see FIG.
As shown in (a), a correction pattern is set for each focal length and correction content, and a pattern is selected and designated from among them. For example, in the camera 2-1, for the wide angle W, the magnification chromatic aberration correction and the distortion aberration correction are performed in the pattern b.
1, the peripheral light amount correction is set as a pattern k2, and the sharpness correction is set as a pattern s3.
With respect to -2, for telephoto T, pattern b1 is set for magnification chromatic aberration correction and distortion correction, pattern k2 is set for peripheral light amount correction, and pattern s3 is set for sharpness correction. These patterns are
As shown in FIG. 7B, the image forming system is set in advance for each correction. In developing a camera, it is preferable to design a lens in consideration of image quality deterioration correction information of the image forming system. Thereby, it is possible to select and record from the image quality deterioration correction information prepared in advance in the image forming system.

In any case, on the image forming system side, typical correction information is stored in advance as described above for several patterns, and the correction information of the pattern selected and designated by the camera side and the photographing information are stored. The correction processing is performed according to the distance from the center of the optical axis at the time, and output as print or image data. It is preferable that the image forming system prepares the image deterioration correction information for every photographing condition.
Here, shooting conditions include aperture information, focal length information,
Strobe information and the like can be mentioned. The image quality deterioration correction information (lens correction information) includes magnification chromatic aberration correction,
Image quality deterioration correction information for performing image quality deterioration correction processing such as distortion aberration correction, vignetting correction, blur correction (sharpness correction), or wide-angle distortion correction. The correction formula itself, a correction coefficient, a temporary correction coefficient, or the like may be used. In particular, in the case of a temporary correction coefficient, recalculation is performed based on image processing conditions such as shooting conditions and print size, and correction processing is performed using the result.

Further, in the case of the correction formula, it is more preferable that the order of the correction formula can be increased depending on photographing conditions such as a focal length (wide angle W, standard N, telephoto T) for each camera. This is because, in general, a complex aberration requires a larger order. For example, a compact camera may have a higher order than a film with a lens. This is because the lens of the film with the lens is basically a single focal point and therefore has a good feature and can be corrected with a small order of about the third order. Further, in the case of the wide angle W and the telephoto T, it is preferable that the order is higher than the standard N. This is because wide-angle and telephoto modes have larger aberrations than the standard.

In correcting chromatic aberration of magnification, R, G
The chromatic aberration of magnification is corrected by converting the image magnifications of R and B with reference to the three primary colors of B and B, usually G, and matching the R and B images with the G image. As described above, one parameter for each of R and B may be separately prepared for the two colors R and B other than G as the reference colors, or one parameter for R, B and two colors other than the reference color G. One parameter may be used instead. However, when one parameter is used instead, the signs are reversed.

The blur correction is basically a sharpness correction, and it is preferable that the gains of R, G, and B in the sharpness processing can be controlled and changed independently. It is further preferable that the gain can be changed depending on the location in the image. For example, an image is divided into blocks, and the gain is changed for each block. Alternatively, the sharpness intensity may be changed according to the distance from the center of the image, the standard intensity may be set at the center, and the gain may be increased toward the end.

In the above-described example, magnification chromatic aberration correction information, distortion aberration correction information, and the like represented by a correction formula, a correction coefficient, and the like for performing image quality deterioration correction processing are used as image quality deterioration related information.
Vignetting correction information and blur correction (sharpness correction)
Although information or image quality deterioration correction information (lens correction information) such as wide-angle distortion correction information is used, the present invention is not limited to this. Apart from image quality deterioration correction information or in addition to image quality deterioration correction information, image quality deterioration The information itself, that is, chromatic aberration of magnification information, distortion information, peripheral dimming information and blurring (focus blurring) information, image quality deterioration information (lens information) such as wide-angle distortion information itself, for example, the intensity of these various image quality deteriorations (and (Pixel position) or a pattern may be used.
In order to correct the image quality deterioration using the image quality deterioration information (lens information) on the image forming system side, it is necessary to correct the image quality deterioration according to the above-described various image quality deterioration strengths (and pixel positions) and patterns. It is preferable that the image forming system stores the correction formula and the correction coefficient for performing the processing.

When the photographer specifies image quality deterioration related information (including image quality deterioration information) represented by the image quality deterioration correction information at the time of photographing with the camera 1, the image forming system side outputs an image (print or image). It may be possible to set whether or not to perform image quality deterioration correction processing on (data). Further, the setting may be linked to the shooting mode. In the case of a film camera, this information is recorded optically as a bar code, for example, at the end of the film as described above, magnetically recorded on a magnetic recording portion of the film, or a film with an IC. In the case of a cartridge, the recording is performed by a method such as electrical recording on the IC. In the case of a digital camera, the image data is recorded by being attached to image data, recorded in a header of the image data, or embedded in the image data by a method such as a digital watermark. Also, information is recorded on a film camera, such as a film, a patrone, a film cartridge, a film cartridge with an IC, and on a digital camera, a smart media, a compact flash (registered trademark), or a PC card. , Memory stick, multimedia card and / or internal memory,
Various (image data) recording media such as a hard disk are applicable.

The timing of recording such information on a film or a recording medium by a camera is most commonly at the time of photographing or before or after photographing, but is not limited to this. May be loaded or taken out of the camera. In the case of a film with a lens, image quality deterioration correction information (lens correction information) may be optically recorded on the film in advance with a barcode at the time of film production. Optical recordings may be made on rod codes at the beginning and end of the film, which are freely available to the film maker. Alternatively, the magnetic layer of the APS film may be magnetically recorded in advance, or if the film is a lens-equipped film using an IC-equipped film cartridge, the image quality deterioration correction information may be electrically stored in the cartridge in advance during film production. You can also keep a record.

In the case of a digital camera, it is possible to specify a correction pattern including whether or not to perform image quality deterioration correction while reproducing a photographed image after photographing and checking the image for each frame. When ordering from the laboratory, the order may be recorded on an order sheet (customer card) or the like. Alternatively, the image quality deterioration correction information may be specified and ordered via a communication network such as the Internet. In addition, all the frames of the APS film are usually photographed by a single camera, but some APS cameras have a midway exchange (MRC) function.
When a single APS film is shot by a different camera using the midway exchange function of the APS camera, the above information is recorded before and after the midway exchange. Also,
In the case of a camera such as a compact camera, a film with a lens, a twin-lens reflex camera and a digital still camera which cannot exchange lenses, a film or a recording medium is used.
It is preferable that image quality deterioration related information such as image quality deterioration information and image quality deterioration correction information designated according to the camera is automatically recorded when the camera is loaded into or taken out of the camera.

On the camera side, in addition to the above-described image quality deterioration correction information, among the focal length information, aperture information, lens type identification information, manufacturer identification information, camera type identification information, flash information, image quality deterioration identification information, etc. At least one piece of information may be recorded in the same manner. For example, when strobe information such as strobe on / off information and strobe light distribution characteristics is recorded, strobe light distribution correction can be performed in the same manner as peripheral dimming correction. Note that the image quality deterioration identification information is identification information indicating various predetermined image quality deterioration levels. Also, the manufacturer identification information (maker code,
When the URL is recorded, as shown in FIG. 8, the image processing apparatus 14 of the image forming system obtains this information and sends it to the maker's server 90 via a communication network such as the Internet. The user accesses or refers to or downloads the image quality deterioration correction information, and performs correction processing using the information. Specifically, when making corrections with reference to the image quality deterioration correction information, the referred image quality deterioration correction information is not stored in the image forming apparatus side, but accesses the maker's server 90 every time to execute the image quality deterioration correction information. You need to refer to When the image quality deterioration correction information is downloaded and corrected, if the downloaded image quality deterioration correction information is stored in the image forming apparatus, the next time image data captured by the same camera is processed, The correction can be performed using the stored image quality deterioration correction information, and it is not necessary to access the maker side each time. Of course, even when the image quality deterioration correction information is downloaded, the information may be stored in the maker's server 90 every time without storing the information. The server 90 of the manufacturer may be accessed using at least one of the camera identification information and the lens identification information in addition to the manufacturer identification information. As a result, strictly matched lens correction information can be obtained, and higher quality correction processing can be performed. As described above, if there is the maker identification information or the camera identification information and the lens identification information, the image quality deterioration correction information can be obtained from the maker and the correction can be performed without the image quality deterioration correction information.

As a result, each camera manufacturer only needs to support the lens correction information of the camera of the manufacturer itself, so that the burden is reduced and the services unique to the manufacturer (contents, templates, advertisements, etc.) are correspondingly reduced. , Quality information, etc.) can be added. In the case where quality information is added and a factor that can be corrected by image processing is added to the quality information, a higher quality image can be obtained by performing image processing and correcting. Here, the content is an extra print or a movie, and the template is
This is a service such as combining a character or character suitable for a shooting frame with a template. Also, as advertising,
In the case of print output, new products and services may be printed on the front and back of the print or in the margins of the index print, and in the case of image data output, these contents may be output to a file. .

In the lab, when receiving an order for printing or the like,
For example, if the order is a film order, the scanner 12 first scans the film to read an image. The image data read by the scanner 12 is sent to the image processing device 14, and the pre-scan data is stored in the pre-scan memory 60 and the main scan data is stored in the main scan memory 62, as described above. The image quality deterioration correction information recorded as a barcode at the end of the film F is read by the barcode reader 38 together with the photographing information, and is read by the CPU 54 via the CPU bus 80.
Sent to Accordingly, from the image quality deterioration correction information stored in the internal memory 56 in advance by the system, information corresponding to the image quality deterioration correction information read from the film F is read by the CPU 54 and supplied to the aberration correction unit 76. You.

When the image quality deterioration correction information is designated by the customer card at the time of ordering, the operator inputs the image quality deterioration correction information from the keyboard 18a or the like. Also,
At the same time, the photographing information read by the barcode reader 38 is sent to the image processing condition setting unit 82 of the condition setting unit 68. The image processing conditions are set in the condition setting section 68, whereby the image processing is performed on the main scan data, output as a finished print from the printer 16, or sent to the external memory 19, from which a predetermined recording medium is stored. Is output as image data.

As described above, the CPU 54 compares the image quality deterioration correction information on the camera side obtained from the film F with the image quality deterioration correction information previously stored in the internal memory 56 on the image forming system side to correspond. In this case, the number of correction patterns supported by the image forming system is different from the number of correction patterns that can be specified by the camera. In such a case, the following measures are taken.

First, when the number of correction patterns held on the image forming system side is larger than that on the camera side, FIG.
As shown in (1), on the image forming system side, pattern A specified on the camera side corresponds to pattern 1 on the system side, and pattern B on the camera side corresponds to pattern 3 on the system side. Just do it. When the number of correction patterns that can be specified on the camera side is larger than the number of correction patterns held on the image forming system side, as shown in FIG.
A pattern A on the system side is assigned to the closest one prepared by the system side. However, in this case, the performance is considered to be slightly reduced. Therefore, in this case, as shown in FIG. 11, an interpolation operation is performed by using the image quality deterioration correction information of the correction pattern already existing in the image forming system to calculate a new correction pattern. This gives a reasonably good performance.
At this time, the timing at which the interpolation calculation is performed is performed when the CPU 54 refers to the correction pattern stored in the internal memory 56 and there is no corresponding correction pattern.

The aberration corrector 76 corrects the chromatic aberration of magnification and the distortion of the image photographed on the film F by the image processing using the image quality deterioration correction information and the position information of the image. This makes it possible to stably output a print in which a high-quality image without color shift or distortion is reproduced. Hereinafter, processing in the aberration correction unit 76 will be described. The aberration corrector 76 uses the image quality deterioration correction information and the pixel position of the image data to determine the amount of deviation of the R and B pixel positions from the reference color (G) due to the chromatic aberration of magnification,
From the shift amount of the pixel position of the reference color caused by the distortion,
An appropriate position for each pixel is calculated, and using the calculated information on the appropriate position of each pixel, image data of each pixel is interpolated to perform electronic scaling of the image. That is, by calculating the amount of deviation of the pixel position due to chromatic aberration of magnification and distortion, it is possible to detect where each pixel should be originally located, and perform interpolation calculation of image data according to the appropriate position. Performs electronic scaling. Thereby, the correction of the distortion and the chromatic aberration of magnification and the electronic scaling process can be performed by one interpolation calculation.

The aberration correction section 76 has a coordinate conversion processing section and an enlargement / reduction processing section for implementing the above processing method. When the image data is supplied, the coordinate transformation processing unit uses the image quality deterioration correction information to shift the deviation amounts Δr and Δb due to chromatic aberration of magnification with respect to the G image data ig at the pixel positions ir and ib of the R and B image data.
, And the shift amount D of the G input image data ig due to distortion is calculated. Next, the pixel position ir of the R image data in which the chromatic aberration of magnification and the distortion have been corrected is calculated by adding Δr and D to each pixel position ir of the R input image data. Position ib
, The pixel position ib of the image data of B in which the chromatic aberration of magnification and the distortion have been corrected is calculated by adding
Is added to each pixel position ig of the input image data of
The pixel position ib of the image data of B whose magnification chromatic aberration and distortion have been corrected is calculated. In this calculation, the chromatic aberration of magnification of the R image and the B image is corrected based on the G image, all the images are aligned with the G image, and the entire distortion is calculated using the shift amount D due to the distortion of the G image. The aberration is corrected, and the pixel position of each of the R, G, and B images in which the chromatic aberration of magnification and the distortion are corrected is calculated.

Next, in the enlargement / reduction processing section, the pixel positions ir and ig in which the chromatic aberration of magnification and the distortion have been corrected.
By performing an interpolation process (N-fold interpolation) of image data according to the enlargement / reduction magnification using, and ib, magnification of the image is performed, magnification chromatic aberration and distortion are corrected, and electronic magnification is changed. It is output as processed image data. Note that when the distortion is corrected, the image in the reproduction area may be lost, that is, so-called vignetting may occur. Therefore, when the distortion is corrected, the correction is 0.1 to 5% lower than usual.
It is preferable to perform the electronic scaling process (interpolation) at a relatively high scaling factor. Further, the electronic magnification at that time may be set variously in accordance with the image quality deterioration correction information. Also, the amount of distortion is
Since the image may be different vertically and horizontally, the magnification of the electronic scaling process may be changed vertically and horizontally. In such a case, aberration correction processing such as lateral chromatic aberration and distortion may be performed vertically and horizontally simultaneously, that is, as two-dimensional processing, or separately vertically and horizontally, that is, as one-dimensional processing.

These correction processes are performed in accordance with the specified correction pattern. In the above example, both the distortion and the chromatic aberration of magnification are corrected as a preferable mode. However, it is specified that only one of them is performed. May be. Also in this case, instead of separately performing the aberration correction and the electronic zooming process, similarly to the above-described method, a proper position in which the shift amount due to the aberration is corrected is calculated, and information on the proper position is calculated. It is preferable to perform electronic scaling by interpolating the image data using. Furthermore, not only distortion and chromatic aberration of magnification,
Correction processing for vignetting, blurring, and wide-angle distortion caused by the lens may be performed. The image data subjected to the aberration correction is subjected to other necessary image processing such as sharpness processing and dodging processing in a block 75, and is sent to an image data conversion unit 78. Here, the sharpness processing is performed after performing the aberration correction, but the aberration correction may be performed after performing the sharpness processing. However, in terms of image quality, it is more advantageous to perform the sharpness processing after performing the aberration correction as in the present embodiment. As described above, such image deterioration correction processing may be performed as two-dimensional processing simultaneously in the vertical and horizontal directions, or may be performed as one-dimensional processing separately in the vertical and horizontal directions. The correction processing is performed based on the designated image quality deterioration correction information. However, fine adjustment may be performed according to an instruction of an operator or the like, so that the processing effect can be further enhanced.

The image data converter 78 converts the image data into image data according to the image recording by the printer 16 and sends the image data to the printer 16. The printer 16 exposes the photosensitive material (printing paper) according to the image data to record a latent image, and performs a developing process according to the photosensitive material (finished).
Output as a print. Further, if necessary, the image data after the image processing including the processing such as aberration correction is output to the external memory 19 as it is, and from there, various recording media such as a smart media, a compact flash, a PC card, a memory stick, a multimedia card, etc. May be output.

As described above in detail, according to the present embodiment, basically, a typical correction pattern is held in advance in the image forming system, and the camera selects and designates from among the correction patterns. In addition, if the camera side does not have the specified one on the system side, the closest one is substituted or the interpolation information is calculated from the closest one to calculate the correction information. In addition, since only the representative image quality deterioration correction information needs to be stored, the storage capacity can be reduced. Also, the information to be recorded on the camera side can be, for example, a pattern number, and thus can be reduced. Further, when a camera is developed, optimal correction can be obtained by designing a lens based on image quality deterioration correction information (lens correction information) of a representative correction pattern prepared in advance in the present system. Further, by combining the photographing means (camera) and the image forming system in this manner, an even higher quality image can be obtained, and the attraction of the camera increases.

Although the camera and the image forming system of the present invention have been described in detail above, the present invention is not limited to the above examples, and various improvements and changes can be made without departing from the gist of the present invention. Of course, you may.

[0076]

As described above, according to the present invention, it is possible to cope with an enormous number of cameras released one after another and to store only typical image quality deterioration correction information on the system side. By doing so, the storage capacity can be reduced, and the information recorded on the camera side can be reduced.
