DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital photo printer and the like, which photoelectrically reads an image photographed on a film, performs predetermined image processing, and outputs the image data as image data for recording. It belongs to the technical field of image reading devices.

[0002]

2. Description of the Related Art At present, an image photographed on a photographic film (hereinafter referred to as a film) such as a negative film or a reversal film is printed on a photosensitive material (photographic paper) by projecting an image of the film onto the photosensitive material. The exposure is performed by so-called direct exposure of a photosensitive material.

On the other hand, in recent years, a printing apparatus using digital exposure, that is, an image recorded on a film is photoelectrically read, the read image is converted into a digital signal, and then various image processing is performed. 2. Description of the Related Art Digital photo printers have been put to practical use for recording and printing an image (latent image) by scanning and exposing a photosensitive material with recording light modulated according to the image data.

[0004] In a digital photo printer, a film is read photoelectrically, gradation correction is performed by image (signal) processing, and exposure conditions are determined. Therefore, it is possible to freely perform editing of a print image such as synthesis of a plurality of images by image processing and image division, and various image processing such as color / density adjustment and contour enhancement. Can be output. Further, the image data of the print image can be supplied to a computer or the like, and can be stored in a recording medium such as a floppy disk. Further, according to the digital photo printer, it is possible to output a print with better image quality, which is excellent in resolution, color / density reproducibility, etc., as compared with the conventional direct exposure print.

[0005] Such a digital photo printer basically includes a scanner that photoelectrically reads an image recorded on a film and uses the image data to process (image processing) the image data to determine exposure conditions. An image reading device (input device) including an image processing device for generating image data for scanning, and a printer (output device) for scanning and exposing a photosensitive material in accordance with the image data for recording, performing development processing, and outputting as a print It is composed of

In a scanner, reading light emitted from a light source is incident on a film to obtain projection light carrying an image photographed on the film, and the projection light is transmitted to an image sensor such as a CCD sensor by an imaging lens. The image is read by forming an image and performing photoelectric conversion, and after performing various types of image processing as necessary, the image is sent to the image processing apparatus as image data (image data signal) of the film. In a scanner, an image of each frame photographed on the film is sequentially read one by one by feeding the film by a carrier mounted on the scanner. The image processing apparatus sets image processing conditions from the obtained image data, performs image processing according to the set conditions on the image data, and sends the processed image data to the printer as processed recording image data (exposure conditions). In a printer, for example, if the apparatus uses light beam scanning exposure, the light beam is modulated in accordance with image data sent from the image processing apparatus, and the light beam is deflected in the main scanning direction and the main scanning direction. The photosensitive material is conveyed in a sub-scanning direction perpendicular to the direction, so that the photosensitive material is exposed (burned) by a light beam carrying an image to form a latent image, and then subjected to a development process or the like according to the photosensitive material. Prints (photos) in which images shot on film are reproduced
And

[0007]

In the image reading of such a digital photo printer, usually, a pre-scan for roughly reading an image photographed on a film and a main scan for obtaining image data for recording are performed twice. Is performed, image processing conditions are determined from the pre-scan image data, the main scan image data is processed in accordance with the image processing conditions, and output to the printer as recording image data. Also, in a conventional direct exposure photo printer, an image photographed on a film is read by an image sensor prior to printing of the photosensitive material, and from this image data, the insertion amount of the color filter at the time of exposure and the aperture value of the light amount are determined. Etc. are determined.

However, in such image reading, the characteristic value (base density) of the negative film is prosperous in the image data, and an appropriate image processing condition (exposure condition) corresponding to the image photographed on the film is determined. In some cases, the resulting print may be unsuitable. Therefore, in a direct-exposure photo printer, images of a plurality of frames, for example, all frames are read by an image sensor before printing, and a negative characteristic value is calculated from image data of all frames, and the negative characteristic value and the negative characteristic value are calculated. After determining the exposure conditions for each frame using the image information for each frame,
We are burning. By using this method, it is possible to eliminate the influence of the characteristic value of the negative film on the produced print, and to output a stable and proper print.

However, in this method, it is necessary to send a negative film by a carrier and perform pre-scanning of all frames, and then return the negative film to the first frame or reversely feed it to perform a main scan (printing). Yes, that is, it is necessary to send the film twice by the carrier (two passes), so that it takes a long time to create a print and the efficiency is reduced.

An object of the present invention is a digital image reading apparatus which photoelectrically reads an image photographed on a film, performs predetermined image processing, and outputs the image data as recording image data. An object of the present invention is to provide an image reading apparatus capable of performing quick and highly efficient image reading despite performing a prosperous image processing by determining a film characteristic value from data.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an image reading apparatus according to the present invention will be described in detail based on a preferred embodiment shown in the accompanying drawings.

FIG. 1 is a block diagram showing an example of a digital photo printer using the image reading apparatus of the present invention. The digital photo printer (hereinafter, referred to as a photo printer 10) shown in FIG. 1 basically includes a scanner 12 that photoelectrically reads an image captured on a film F, and image data (image information) that the scanner 12 has read. Image processing apparatus 14 which performs image processing on the image to obtain image data for recording
(Hereinafter, referred to as a processing device 14), a printer (image recording device) 16 that exposes the photosensitive material with a light beam modulated according to the image data processed by the processing device 14, develops the material, and outputs it as a print. Is configured. The image reading device (input device) of the present invention includes a scanner 12 and a processing device 14. The processing device 14 includes an operation system 18 having a keyboard 18a and a mouse 18b for inputting (setting) various conditions, selecting and instructing processing, and instructions for color / density correction, and the like. The display 20 is connected to display an image read in the above, various operation instructions, a setting / registration screen for various conditions, and the like.

The scanner 12 is a device that photoelectrically reads an image photographed on a film F or the like one frame at a time.
And a variable aperture 24 for adjusting the amount of reading light according to the image photographed on the film F;
R, G for separating into three primary colors (green) and B (blue)
And a color filter plate 26 having three color filters of B and rotating to apply an arbitrary color filter to the optical path, and a diffusion box 28 for making the reading light incident on the film F uniform in the surface direction of the film F. , An imaging lens unit 32, and an area sensor C for reading one frame image of the film.
It has a CD sensor 34 and an amplifier (amplifier) 36.

The scanner 1 of the photo printer 10 shown in FIG.
2 includes a new photo system (AdvancedPhoto System) and 1
Depending on the type and size of the film such as a negative film of 35 size, the form of the film such as strips and slides, the type of processing such as trimming, etc., a dedicated carrier that can be attached to the main body of the scanner 12 is prepared. By changing the carrier, it is possible to cope with various films and processes. The film F is fed frame by frame by a carrier, and each frame (image) is sequentially conveyed to a predetermined reading position. In the scanner 12, in this manner,
The image of each frame photographed on the film F is sequentially read one by one.

In such a scanner 12, the reading light emitted from the light source 22, the light amount is adjusted by the variable diaphragm 24, the color is adjusted by passing through the color filter plate 26, and the reading light diffused by the diffusion box 28 is applied to the film F. Incident,
By transmitting the light, projection light carrying an image of the frame captured on the film F is obtained. The projection light of the film F is transmitted to the CCD sensor 34 by the imaging lens unit 32.
An image is formed on the light-receiving surface of the CCD, and is photoelectrically read by the CCD sensor 34. The output signal is amplified by the amplifier 36 and sent to the processing device 14. The CCD sensor 34 is, for example, an area CCD sensor having 1380 × 920 pixels. Further, in the illustrated device, the CCD sensor 34 is configured to be two-dimensionally movable in the pixel array direction by an amount corresponding to a half pixel, whereby the number of read pixels can be apparently increased to four times. Can be.

In the scanner 12, such an image reading is performed three times by sequentially inserting the respective color filters of the color filter plate 26, so that one frame of image is read out by R, G and B.
And read out. Further, in the scanner 12 of the image reading apparatus of the present invention, such image reading is performed continuously for a predetermined plurality of frames, for example, six frames.

Here, the image recorded on the film F, especially on the negative film, is not always proper, and there are many underexposure (under) and overexposure (over) frames. There is a large difference in concentration.
In order to read an image having such a density difference under the same conditions, the reading conditions are set so that the CCD sensor 34 has sensitivity even at the highest possible density in all images and the output is not saturated even at the lowest density. S / N of reading because it is necessary
The ratio and the gradation resolution are greatly reduced. Therefore, in the image reading apparatus of the present invention, prior to image reading for obtaining image data for recording (hereinafter referred to as image reading for output), pre-reading for coarsely reading an image is performed, and image reading for output is performed. It is preferable to optimize the reading conditions for image reading, for example, the reading light amount (light source light amount and aperture amount), the accumulation time of the CCD sensor, and the like according to each frame. In the illustrated example of the photo printer 10, the variable aperture 24
The aperture value and / or the storage time of the CCD sensor 34 are determined and adjusted to optimize the image reading conditions for output for each frame.

The pre-reading for setting the reading conditions may be performed by the CCD sensor 34 prior to reading the output image. Note that unlike prescan for determining image processing conditions, high precision and resolution are not required for pre-reading for determining reading conditions.
The resolution (space and gradation) of the sensor 34 may be reduced. Alternatively, another sensor for pre-reading may be provided. As described above, since high precision is not required for pre-reading, image reading for output may be performed using a different sensor from image reading for output.
Also, the sensor is not required to have such high accuracy and resolution. The pre-reading sensor may be arranged, for example, before the above-described carrier reading position (upstream in the frame feed direction of the film F for reading), or at a position outside the optical path of the projection light. The pre-reading may be performed by arranging the optical sensor at a position optically equivalent to the sensor 34 and providing an optical path changing mirror that can be inserted between the CCD sensor 34 and the imaging lens unit 32. As will be clear from the following description, in the present invention, even if pre-reading is performed, the transport of the film F by the carrier only needs to be performed once (one pass), so that the working time is not significantly affected.

As described above, the output signal (image data) from the scanner 12 is output to the processing device 14. FIG.
As shown in the figure, the processing device 14 includes the A / D converter 3
8, Log converter 40, image memory 42, display means 4
4. It has an image processing condition setting device 46 (hereinafter, referred to as a setting device 46) and an image data processing device 48 (hereinafter, referred to as a data processing device 48). Although FIG. 2 shows only parts related to image processing, the processing device 14 also performs operations and controls of the entire photo printer 10, and the processing device 14 includes components other than the illustrated portions. Also, a CPU that controls and manages the entire photo printer 10, a memory that stores information necessary for the operation of the entire photo printer 10, a means for determining the aperture value of the variable aperture 24 and the accumulation time of the CCD sensor 34, and the like. The operation system 18 and the display 20 are arranged, and are connected to each part via the CPU or the like (CPU bus). Such a processing device 14
Usually, it consists of a computer and a workstation.

Each output signal (image data) of R, G, and B output from the scanner 12 is converted into digital image data by an A / D converter 38, and output by a Log converter 40.
The data is g-converted and stored (stored) in the image memory 42.
An image reading apparatus according to the present invention is an apparatus that continuously reads an image of a plurality of frames, calculates a characteristic value of the film F from the image data, and sets an image processing condition in consideration of the characteristic value. The memory 42 is a frame memory for storing image data corresponding to a plurality of frames, for example, six frames. That is, in the photo printer 10, the film F
Are read continuously for six frames and sequentially stored in the image memory 42. Note that, between the A / D converter 38 and the image memory 42, various corrections such as DC offset correction, darkness correction, and shading correction may be performed on the image data as needed.

In the image reading apparatus of the present invention, the number of frames to be read continuously is not particularly limited. Therefore, if the capacity of the image memory 42 is sufficient, all the frames of the film F may be read continuously, or if the setting value of the film F by the setting device 46 described later can be appropriately determined. Alternatively, reading may be continuously performed every two frames. Normally, in order to properly determine the characteristic value of the film F, image data of at least about 6 frames is required. Therefore, it is preferable that the number of frames to be continuously read is larger than that.

The setting device 46 thins out and reads out the image data of the six frames stored in the image memory 42 sequentially or all at once, creates a density histogram for each frame,
Calculation of image feature values such as average density, maximum density (shadow), minimum density (highlight), LATD (large area transmission density), etc. is performed. decide. Further, image processing conditions for each frame are calculated from the characteristic values of the film F and the image feature amount of each frame, or color / density adjustment by an operator in a later-described test, and the display means 44 and data processing are performed. The setting is made in the device 48.

The characteristic values of the film F are as follows.
The gradation balance among R, G, and B is exemplified. Various known methods can be used for calculating the gradation balance. For example, the relationship between R, G, and B of the film F is determined by the least square method using the highlight and shadow of the image of each frame. Examples include an approximation method and a method using an average density. Note that it is preferable to store the highlight, shadow, and average density of the image of each frame in order to determine underexposure or overexposure. Further, the characteristic value of the film F may be determined independently for every six frames (continuous reading units) that are continuously read, or the characteristic value of the film F and the image data of the new six frames may be used. May be used to update the characteristic values. Alternatively, the data required to determine the characteristic values of the film calculated up to that time may be stored, and every time six frames are read, the characteristic values of the film F may be obtained from all the data having the data. The value may be determined.

The data processing device 48 includes an LUT (not shown)
(Look-up table) and the like. The image data of each frame is sequentially read from the image memory 42, and predetermined image processing is performed in accordance with the image processing conditions set by the setting device 46, for example, Density correction, color balance correction, gradation correction (correction of underexposure and overexposure), electronic scaling (enlargement / reduction of image by image processing), compression and / or expansion of dynamic range while maintaining intermediate gradation ( The image data is subjected to a dodging effect by image processing, a sharpness (sharpening) process, and the like, and output to the printer 16 as image data for recording. Note that the image data for recording is output to a drive of various storage media such as a floppy disk or an MO (magneto-optical recording medium) connected or built in the processing device 14 or the like, and stored in the storage medium. Good. When performing image verification, the display means 44 thins out and reads out image data of each frame from the image memory 42, performs image processing similar to that performed by the data processing device 48, and displays the image data on the display 20.

Hereinafter, the operation of the scanner 12 and the processing device 14 will be described, and the image reading apparatus of the present invention will be described in more detail. When creating a print in the photo printer 10, the operator sets a carrier corresponding to the film F to be an original on the scanner 12, and
A necessary instruction is performed using the mouse 18b or the like. On the other hand,
The photo printer 10 includes the light amount of the light source 22 of the scanner 12 and the like.
After confirming that is in a predetermined state, the operator
The film F is set at a predetermined position of the scanner 12 (carrier), whereby the carrier F is moved to the first position by the carrier.
The frame is conveyed to a predetermined reading position.

When the reading start is instructed, as described above,
Prior to reading an image for output, pre-reading is performed. At the time of pre-reading, the aperture value of the variable aperture 24 and the accumulation time of the CCD sensor 34 are in an initial state set in the scanner 12 according to the type of the film F. The read light emitted from the light source 22 is adjusted in light amount by the variable aperture 24, is dimmed by a filter of the color filter plate 26 inserted in the optical path L, for example, a G filter, and enters the first frame of the film F. Projection light that passes through and carries the image (G image) captured on this frame is obtained. This projection light is transmitted to the imaging lens unit 3
2, an image is formed in the effective pixel area of the CCD sensor 34, the G image of the film F is read, amplified by the amplifier 36, sent to the processing device 14, and A / D converted by the A / D converter 38.
/ D conversion, converted by the Log converter 40, and stored in the image memory 42. When reading of the G image is completed,
Similarly, for example, a B image and then an R image are read and sequentially stored in the image memory 42.

This image data is read out by means for determining the aperture value and the storage time of the CCD sensor 34, which are arranged in the processing device 14, to determine the image reading conditions for output, and to adjust the variable aperture 24. Is performed. When the adjustment of the variable aperture 24 and the like are completed, an image for output is read.
The image reading for output is performed in the same manner as the aperture value of the variable aperture 24, the accumulation time and the resolution of the CCD sensor 34, etc.
Basically, it is performed in the same manner as the pre-reading, and the G, B, and R images of the first frame of the film F are sequentially read and sent to the processing device 14. The image data of the G image, the B image, and the R image obtained by reading the image for output are similarly A / D-converted by the A / D converter 38,
0, and are sequentially stored in the image memory 42, and the image reading of the first frame is completed.

When the image reading of the first frame is completed, the carrier transports one frame of the film F in the scanner 12, and the second frame is transported to the reading position. (Output image reading) is performed and stored in the image memory 42. Hereinafter, similarly, image reading is performed up to the sixth frame, and image data for the six frames is stored in the image memory 42. In addition, continuous image reading
The order is not limited to the order of frame numbers, but may be the order of instructions from the operator.

In parallel with the image reading, the setting device 46
Sequentially converts the image data stored in the image memory 42 into
The data is read out by thinning out, and a density histogram is created for each frame, an image feature amount is calculated, and the like. After completing the calculation of the image feature amounts of all six frames, the setting device 46 determines the characteristic value of the film F from the image feature amounts of six frames. In this example, the highlight and shadow of the six frames are used, and the least square method is used. Thus, the gradation balance between R, G, and B is determined as the characteristic value of the film F. Note that the highlight, shadow, and average density of the image of each frame are stored in order to determine underexposure and overexposure. Next, from the determined characteristic value of the film F and the image feature amount of each frame,
Image processing conditions for each frame are determined from the first frame. The following method is exemplified as a method for determining the image processing conditions. The color balance (gradation balance between R, G, B) correction is performed for the R, G, B of the film F determined as the characteristic value.
The weight of the tone balance is determined by using the tone balance between the frames and the highlight and shadow of the frame, and the final tone balance is determined by using the weight. The underexposure is determined based on a rule that the highlight of the frame is almost the lowest among the six frames and the histogram distribution of the frame is closer to the highlight side.
On the other hand, the overexposure is similarly determined based on the rule that the shadow of the frame is almost the highest among the six frames and the histogram distribution of the frame is closer to the shadow side. Further, the density correction condition is determined based on the average density of each frame.

When image verification is not performed (work mode in which monitor verification is not performed), the setting device 46 sequentially sets the determined image processing conditions in the data processing device 48. Specifically, the color balance correction condition and the density correction condition are set by the setting device 46 as an LUT in the data processing device 48. If underexposure or overexposure is determined, an LUT for correcting the non-linear shape of the foot (high-density portion) or shoulder (constant-density portion) of the film F is provided by the setting device 46 to the data. It is set in the processing device 48. In parallel with the setting of the image processing conditions by the setting device 46, the data processing device 48 sequentially stores the image data of the frames for which the image processing conditions have been set in the image memory 4.
2 and performs correction according to the set image processing conditions, and outputs the image data to the printer 16 as image data for recording.

On the other hand, when performing the image verification (operation mode for performing the monitor verification), the setting device 46 determines the image processing conditions of all the frames and displays the image processing conditions on the display means 4.
4 and the data processor 48. Next, the display unit 44 thins out and reads out image data of all frames from the image memory 42, processes the image data in accordance with the set image processing conditions, and displays images of six frames on the display 20. The display of the image on the display 20 is not limited to all frames, but may be one frame at a time. By displaying a plurality of frames in this manner, comparison with the previous and next frames can be performed, and the verification work can be easily performed. There is an advantage.

The operator looks at the image displayed on the display 20 and performs a test for each frame, and adjusts the gradation and color / density of the image using the operation system 18 as necessary. In accordance with this adjustment, the image processing conditions set in the display unit 44 and the data processing device 48 are corrected, and the image displayed on the display 20 also changes. When the operator determines that the image is appropriate (test OK) and issues an output instruction, the data processing device 48 sequentially reads out the image data from the image memory 42, performs the same image processing as before, and performs recording. Is output to the printer 16 as image data. Note that the output instruction may be performed for all images at once,
The test may be sequentially performed for each frame according to the end of the test.

When the image processing of six frames is completed in this way, the scanner 12 operates in the same manner as the above-described image reading.
Image reading of the next six frames (the seventh to twelfth frames in this example) is started. Alternatively, the image reading may be started when one frame of image is read from the image memory 42, that is, when the image memory 42 is opened.

As described above, according to the image reading apparatus of the present invention, in order to stably record a higher quality image, the characteristic value of the film F is determined from the image data of a plurality of frames.
Despite determining the image processing conditions taking that into account,
The scanner 12 can perform image reading by one-pass film transport, and can perform a quicker and more efficient operation. Further, even if the pre-reading for determining the reading conditions is performed, a high resolution and accuracy are not required for the pre-reading, so that an increase in the reading time is small.

As described above, the image data for recording processed by the data processing device 48 is basically transmitted to the printer 16.
Is output to The printer 16 includes, for example, a light source that emits a light beam corresponding to each of the R, G, and B exposures according to the spectral sensitivity characteristics of the photosensitive material, a light beam modulation unit such as an AOM (acousto-optic modulator), and a polygon mirror. Optical deflectors, etc.
a processing device 14 (data processing device 48) having a known light beam scanning exposure having an fθ lens or the like;
Modulates the light beam according to the image data sent from
The light beam is deflected in the main scanning direction and the photosensitive material is conveyed in a sub-scanning direction orthogonal to the main scanning direction, thereby exposing (burning) the photosensitive material with the light beam carrying an image to form a latent image. Then, the film is subjected to a development process or the like according to the photosensitive material, and the image photographed on the film is output as a reproduced print (photograph).

Although the image reading apparatus of the present invention has been described in detail above, the present invention is not limited to the above embodiment, and various improvements and modifications may be made without departing from the gist of the present invention. Of course.
