Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic image information recording apparatus, and more particularly to a photographic image information recording apparatus used in a digital photographic image processing system which is a new generation film photographic image processing system.

[0002]

2. Description of the Related Art In current film photo processing systems,
The user takes the filmed film to the DPE store,
Take the film to a large-scale laboratory (film development, image printing place) at the DPE store, develop the film, print the image on photographic paper, etc., and print it with the developed film to the user via the DPE store. It is a system that returns photos taken. In recent years, as minilabs have become smaller, some minilabs have been installed in DPE stores.

In this type of minilab, film (negative,
(Including positive) is developed with a film processor, and the developed film is optically stretched with a minilab printer,
Processing such as printing is performed, and then processing for developing the image on the photographic paper is performed by the minilab processor. Since all of the above minilab film photographic systems are processed in an analog manner, there are naturally limits to processing such as color balance adjustment, density adjustment, and color conversion.

Therefore, a system for converting image information recorded on a developed film into digital image data and digitally processing the image has been developed.
Once the analog image information has been converted into digital image data, data processing becomes possible even if a CPU is used, so there is a great potential for development of a digital photographic image processing system. If the image-processed data is returned to an analog image signal using a D / A converter, a good image can be printed on recording paper, photographic paper, or the like.

In recent years, a digital photographic image processing system (hereinafter simply referred to as a photo CD system) using a CD (compact disc) as a memory has been developed. This photo CD system uses a CD-R as an image information storage medium, and when the user takes a film of a photographed film, it returns a film image recorded on a CD. After that, the user can save this CD and print the image on the recording paper with the photo CD system when necessary. The number of frames that can be recorded on Photo CD is 100
The number of sheets is about 24, and four frame images can be recorded on a 24 shot film. Since this type of Photo CD system digitally performs an intermediate image processing step, it can meet a variety of user requests.

In addition, in recent years, there has been developed a film capable of recording not only a DX code but also various photographing information such as photographing environment information. This new film is
It has a magnetic recording layer, and various information is digitally recorded on this magnetic recording layer. This film is contained in a film cartridge 10 as shown in FIG.
With the film in the film cartridge 10,
The film which is mounted on the camera and photographed is rewound into the film cartridge 10 again. Then, when the film cartridge 10 is brought to the developing place, the developed film is returned to the user in a state of being housed in the cartridge together with the printed photograph. In FIG. 8, 1 is a take-up spool for winding a film, 2 is a film drawing port, and 3 is a film. The film 3 may be negative or positive.

[0007]

In the photo CD system described above, since the CD-R is used as the image information storage medium, it is possible to write and read once.
There is a problem that it cannot be rewritten. Further, there is a problem that the device is large and the cost is high. Therefore, the applicant of the present invention uses a rewritable image information storage medium,
We have developed a new digital photographic image processing system with low cost and good operability.

In the case of the new type of film mentioned above,
When shooting a subject with a camera, not only the shooting date but also flash shooting, backlight compensation, exposure compensation, etc. are recorded for each frame. However, when the film is image-processed and written in the rewritable image information storage medium, the image processing with the color balance of the entire film is performed, so that the color correction and the brightness correction according to the shooting condition of each frame cannot be performed. It wasn't done. For this reason,
The print image created was not an image that was well-balanced in color according to the shooting conditions for each frame, or was the image intended by the photographer.

The present invention has been made in view of the above problems, and is a photographic image information recording apparatus capable of recording a frame image having a color balance for each frame or a color intended by a photographer. Is intended to provide.

When the content read by the photographing information reading means is the backlight photographing information, the image correcting means changes the γ characteristic curve for the frame image in which the backlight photographing information is recorded. It is preferable to make a correction in order to obtain an image in which the backlight portion is brightened.

Further, when the content read by the photographing information reading means is the exposure correction information, the image correcting means corrects the brightness of the frame image in which the exposure correction information is recorded. However, it is preferable for obtaining the image intended by the photographer.

[0015]

FIG. 2 is a flow chart showing the operation of the first embodiment of the present invention. (1) Pre-scan mode The developed film cartridge 10 or the bare film 3 (negative or positive) may be mounted on the film mounting portion 20 and pre-scanned for one film, and the memory portion 3
3 (S1). The details are as follows.

The image information recorded on the film 3 is read by the CCD in the film scanner section 31. In this case, it is not necessary to provide channels according to the type of film, and all channels are read. When reading with the CCD, the pixels of the CCD are decimated and read, or integrated to reduce the number of pixels and read when compared with the main scan. In the pre-scan, the read photographic image data is not written in the MD 50 but is used for determining the characteristics of the film, adjusting the color balance, index printing, etc., and the pixel density need not be so high. For example, the pixel density during the main scan is 2048 × 30 per screen.
When the number of pixels is 72 pixels, 1 per screen in prescan
Read with a density of about 28 × 192 pixels. in this way,
By thinning and reading, the time required for image processing can be shortened.

The determination as to whether the film is negative or positive is made by a discriminator (not shown) provided in the CCD reading section, and the inside of the image processing section 32 is determined according to the type of negative and positive. Conversion characteristics of one-dimensional LUT and 3 of color correction unit 35
Although it is necessary to change the conversion characteristic of the dimension LUT 35a, the case of a negative film will be described below.

The photographic image data read by the CCD of the film scanner unit 31 is converted into digital photographic image data for each of R, G and B by an A / D converter. The converted digital photographic image data is transferred to the subsequent image processing unit 32.
After receiving the predetermined image processing, the memory unit 33 is sequentially operated.
It is stored in the main memory inside. Hereinafter, the overall control unit 40
Performs the following processing on the photographic image data for one film stored in the memory unit 33.

Frame Position Discrimination The overall control unit 40 performs frame position discrimination processing on the photographic image data stored in the memory unit 33 (S2). When the film is pre-scanned, the entire film is stored in the memory unit 33. Therefore, it is necessary to determine the frame position. In the case of the film used in this embodiment, since the perforations are always provided at the boundaries between the frames, the perforation detection unit (not shown)
This makes it easy to determine the frame position. Alternatively, in the image information read by the film scanner unit 31, the perforation unit has data that can be clearly discriminated from the other regions, so that it is possible to discriminate between frames by image processing.

Discrimination of Panorama / Normal Image Type Next, the overall control unit 40 performs a discrimination process between a panoramic image and a normal image (S3). The overall control unit 40 determines the panorama / normal image using a predetermined determination algorithm.

When the processes of and are completed, the overall control unit 40 next reads the prescan image stored in the memory unit 33, transfers it to the video memory in the CRT control unit 38, and displays it on the CRT 39 (S4). . Then, it is checked whether or not the frame position of the displayed image is OK (S5). At this time, the image displayed on the CRT 39 is an image in which the boundaries between frames determined by the normal process are shown. The operator is CRT3
When the position displayed on 9 is incorrect, the operation unit 4
The frame position correction work is performed from 1 (S6).

When the frame position is displayed correctly,
The overall control unit 40 creates a histogram for each frame (S7). Next, it is checked whether or not there is a flash for each frame image (S8). Information about whether or not a flash is provided for each frame is notified to the overall control unit 40 in advance by the output of the photographing information reading unit 22. When the film is pre-scanned, the shooting information for each frame is read by the overall control unit 40 and stored in the internal memory together with the frame number. Therefore, the overall control unit 40 uses the memory unit 33.
The shooting information of the frame images sequentially read from can be recognized.

When there is flash photographing, a histogram is created for all frames with flash photographing corresponding to the flash photographing (S9), representative brightness point extraction for each frame (S10), color of the entire film with flash. A process such as balance extraction (S11) is performed, and R is set so that an image with optimum characteristics can be obtained based on the process result.
One-dimensional LUT for prescan of the GB → YMC conversion unit 34
The gradation curve is written in (S12). By this processing, it becomes possible to obtain an optimum image in which the characteristics of the film are corrected for all frame images with flash.

The same applies to the processing when there is no flash photography. That is, a histogram is created for the entire frame without flash photography (S9 '), representative brightness point extraction for each frame (S10'), color balance extraction of the entire film without flash (S11 '), etc. are performed. A gradation curve is written in the pre-scanning one-dimensional LUT of the RGB → YMC conversion unit 34 so that an image having optimum characteristics can be obtained based on the processing result (S12 ′). By this processing, it becomes possible to obtain an optimum image in which the characteristics of the film are corrected for all frame images without flash.

After the gradation curve is written in the pre-scan scan one-dimensional LUT, the pre-scan image stored in the memory section 33 is passed through this one-dimensional LUT to display the CRT.
It is stored in the video memory in the control unit 38. C
The prescan image having the corrected characteristic is displayed on the RT 39 (S13). Here, the operator is CR
The display image at T39 is checked to check whether the color, brightness, etc. are optimum (S14). R if not optimal
In the GB → YMC conversion section 34, the operator corrects the color and brightness in the operation section 41 so that the image display of the CRT 39 becomes the optimum color (S15). This correction operation is a process of changing the curve of the one-dimensional LUT.

In the correction process described above, Y, M, C of the subtractive color system
Since the correction is based on the characteristics, there is an effect that the operator can easily operate. When the correction processing is completed, this characteristic is now analyzed by the one-dimensional LUT for the main scan (image processing unit 3
Give feedback to 32a) in 2. That is, the corrected gradation curve is written in the one-dimensional LUT for the main scan (S16). FIG. 3 is a diagram showing a configuration example of the one-dimensional LUT 32a. One-dimensional LUT 60 for flash photography
And a one-dimensional LUT 61 for normal shooting.

As shown in FIG. 4, the developed film is composed of a frame (◯) with flash photographing and a normal photographing frame (×). Here, an example of taking every 24 shots is shown.
Therefore, when performing image processing, the one-dimensional LUT 60 at the time of flash shooting is used in the case of flash shooting frames.
In the case of a normal shooting frame, a one-dimensional LUT 61 during normal shooting
To use. The prescan operation is completed by the above processing.

If necessary, all the frames of the film image optimized by the above processing can be displayed on the CRT 39, the frame images can be confirmed, and then the frames can be written in the MD 50 for index printing. The index image stored in the MD50 is exposed to photographic paper using a separately prepared photosensitive device (for example, a CRT printer), and then developed and fixed by a minilab processor (not shown) to create an index print. By attaching this to the surface of the MD 50 in which the frame image data is written or the protective case (jewel case) of the MD 50, the user can confirm what kind of image is shown in which frame, which is convenient. Good.

(2) Main scan mode In the main scan, the film image is formed using all the pixels (for example, 2048 × 3072 pixels) of the CCD (S
17). R, photoelectrically converted by the film scanner unit 31,
The G and B analog image signals are digital photographic image data (for example, 11) for each R, G and B by the subsequent A / D converter.
Bit) and sent to the image processing unit 32. In the one-dimensional LUT 32a in the image processing unit 32, optimum gradation conversion curves determined by prescan are separately stored for flash photography and for normal photography (see FIG. 3). The frame image taken by flash passes through the one-dimensional LUT 60 at the time of flash shooting, and the frame image taken by normal shooting passes through the one-dimensional LUT 61 at the time of normal shooting. The distribution control is performed by the overall control unit 40. Therefore, the digital photographic image data obtained by the main scan is the one-dimensional LU.
Due to T32a, optimum image conversion processing is performed for each of flash photography and normal photography.
The film photographic image data obtained by the main scan is temporarily stored in the main memory in the memory unit 33 (S1).
8).

The film photographic image data once stored in the main memory is read out frame by frame and RGB → YMC
The conversion unit 34 is passed through and enters the color correction unit 35. The three-dimensional LUT 35a of the color correction unit 35 is a three-dimensional LUT for converting the characteristics of the input image data, and the photographic image data not stored in the LUT is interpolated and output by a predetermined method. From this 3D LUT, R,
The G, B image data is output as new R, G, B image data. The output of the three-dimensional LUT is the selector 36
Is stored in the video memory in the CRT control unit 38 via the and displayed on the CRT 39. The operator can see the optimum image for each frame.

(3) Writing of photographic image data to MD The output of the color correction section 35 enters the MD processing section 42 through the selector 36, and is subjected to JPEG format image compression and J
The photographic image data is compressed according to the PEG standard.
Next, the compressed photographic image data enters the internal MD drive, and the MD drive writes the photographic image data in the MD 50 (S19). In this way, the photographic image data subjected to the optimum color correction for each frame is sequentially written in the MD 50. As described above, according to the present invention, it is possible to record a frame image having a color balance for each frame or a color intended by the photographer. Further, according to the first embodiment shown in FIG. 2, when the content read by the shooting information reading unit 22 is the flash shooting information, for the frame image in which the flash shooting information is recorded,
By performing color correction, it is possible to obtain an image with a well-balanced color.

FIG. 5 is a flow chart showing the operation of the second embodiment of the present invention. This embodiment shows a processing flow when the shooting information is backlight shooting. In the case of backlight shooting, the image near the center of the frame becomes dark. In this embodiment, therefore, correction is performed to brighten the image near the center of the frame. In FIG. 5, step S15
The operation up to this point is the same as that of the first embodiment shown in FIG.

After writing the gradation curve in the one-dimensional LUT 32a for the main scan (S15), the overall control unit 40 carries out the main scan of the film 3 (S16). The frame image data obtained by the main scan is sequentially stored in the main memory of the memory unit 33 (S17).

On the other hand, the information as to whether or not the backlight is photographed for each frame is notified to the overall control unit 40 in advance by the output of the photographing information reading unit 22. When the film is pre-scanned, the shooting information for each frame is read by the overall control unit 40 and stored in the internal memory together with the frame number.
Therefore, the overall control unit 40 can recognize the shooting information of the frame images that are sequentially read from the memory unit 33.

The overall control unit 40 reads out the frame images one by one from the memory unit 33 and checks whether or not the frame is a backlit frame (S18). In the case of a backlit frame, correction is performed to brighten the vicinity of the center of the image (S19). Specifically, the curve of the three-dimensional LUT 35a of the color correction unit 35 is corrected to raise the brightness near the center of the image. Memory part 3
The frame image data read from 3 is RGB → YMC
The conversion unit 34 is passed through to enter the three-dimensional LUT 35a, and the R, G, and B are respectively corrected to be brightened by the three-dimensional LUT 35a. 3 if not a backlit frame
The curve of the dimensional LUT 35a remains unchanged. In this way, the frame image data for which color correction has been completed enters the MD processing unit 42 via the selector 36 and is written in the MD 50 (S20). According to the second embodiment, it is possible to obtain an image in which the backlight portion is brightened by performing a correction for brightening the vicinity of the center of the image captured by backlighting. An image that is not backlit is written in the MD 50 with its color corrected accordingly.

In the above-described embodiment, the case where the correction is performed to brighten the image near the center of the backlit frame image is taken as an example, but the present invention is not limited to this. When performing γ correction on an image, it is also possible to make an image darkened by backlighting bright by changing the γ characteristic curve.

FIG. 6 is an explanatory diagram of the γ characteristic curve. In the figure, the horizontal axis is the light amount and the vertical axis is the signal level. f1 indicates a normal correction characteristic. In the case of backlight, the area near the center of the image appears dark. Therefore, as shown by the characteristic f2, if the conversion is performed so as to raise the dark part of the image, the backlit part can be made brighter. This γ conversion unit is
It can be provided at an appropriate place in the block diagram shown in FIG. For example, it can be provided in the RGB → YMC conversion unit 34 and the color correction unit 35. Even in this case, it is possible to obtain an image in which the backlight portion is brightened.

FIG. 7 is a flow chart showing the operation of the third embodiment of the present invention. This embodiment shows a processing flow when the shooting information is an exposure correction frame. Even in the case of an exposure-corrected frame image, if it is recorded on the MD 50 after being subjected to color correction of the entire film, the image when printed will be linked with the image correction characteristics of the entire film, and will not be the image intended by the photographer. . Therefore, the frame for which the exposure has been corrected is corrected so that the image has the brightness as intended by the photographer.

In FIG. 7, the operation up to step S15 is the same as that of the first embodiment shown in FIG. 2, and therefore its explanation is omitted. After the gradation curve is written in the main scan one-dimensional LUT 32a (S15), the overall control unit 40 performs the main scan of the film 3 (S16). The frame image data obtained by the main scan is sequentially stored in the main memory of the memory unit 33 (S17).

On the other hand, the information as to whether or not the exposure is corrected for each frame is notified to the overall control unit 40 in advance by the output of the photographing information reading unit 22. When the film is pre-scanned, the shooting information for each frame is read by the overall control unit 40 and stored in the internal memory together with the frame number. Therefore, the overall control unit 40 uses the memory unit 33.
It is possible to recognize the shooting information of the frame images to be sequentially read from.

The overall control unit 40 reads out the frame images one by one from the memory unit 33 and checks whether the frame is an exposure correction frame (S18). In the case of an exposure correction frame, the overall control unit 40 performs brightness correction that matches the exposure correction of the frame (S19). Specifically, the curve of the three-dimensional LUT 35a of the color correction unit 35 is corrected so that the desired brightness can be obtained. The frame image data read out from the memory unit 33 passes through the RGB → YMC conversion unit 34 through and enters the three-dimensional LUT 35a, and the R, G, and B respectively have the brightness desired by the photographer in the three-dimensional LUT 35a. Brightness correction is added so that If it is not the exposure correction frame, the curve of the three-dimensional LUT 35a is left as it is.
In this way, the frame image data after color correction is
The MD processing unit 42 is entered through the selector 36, and the MD 50
(S20). According to the third embodiment, the image intended by the photographer can be obtained for the image of the exposure correction frame. An image which is not an exposure correction frame is written in the MD 50 in a state where the color is corrected as it is.
