In the illustrated example of the photo printer 10, a cartridge of a new photo system (Advanced Photo System) or a 135 size negative (or reversal) is used.
Depending on the type and size of film such as film, the form of 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, and the carrier can be replaced. Thereby, it can respond to various films and processes. When reading an image photographed on a 135-size negative film or a film of an IX240 cartridge of a new photograph system, each frame to be printed is sequentially transported to a predetermined reading position by a carrier and photographed on these frames. Images are read sequentially. A magnetic head that reads information recorded on a magnetic recording medium formed on a film of the new photo system and records the information is arranged on a carrier corresponding to the cartridge of the new photo system. The information recorded on the magnetic recording medium of the film is read by the carrier and sent from the main body of the scanner 12 to a necessary portion such as the image processing device 14 or the information from the image processing device 14 is transmitted from the main body of the scanner 12.

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, and is photoelectrically read by the CCD sensor 34. The output signal is amplified by the amplifier 36 and sent to the image processing device 14. CCD sensor 34

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 by R, G and B.
And read out. Here, the photo printer 10 normally performs a pre-scan for reading an image at a low resolution in order to determine image processing conditions and the like, before reading an image for printing a print P (main scan). Therefore, at this time, a total of six image readings are performed for one frame.

Each part is connected via a PU or the like (CPU bus).

First, the R, G, and B output signals output from the scanner 12 are first sent to the data conversion unit 38.
A / D (analog / digital) conversion and Log conversion are performed to obtain digital image data (input image data).
Next, in the data processing section 54, predetermined processing such as DC offset correction, dark time correction, shading correction and the like is performed.
0, the main scan image data is stored in the main scan memory 42.
Are respectively stored (stored). The pre-scan (image) data and the main scan (image) data are basically the same data except that the pixel density and the signal level are different. In the illustrated example, since the aperture value of the variable aperture 24 at the time of the main scan is set based on the prescan data, the two data have different signal levels.

The pre-scan data stored in the pre-scan memory 40 is processed in the pre-scan image processing section 44, and the main scan data stored in the main scan memory 42 is processed in the main scan image processing section 46. The pre-scan image processing unit 44 includes the image processing unit 5
0 and a signal processing unit 52. On the other hand, the main scan image processing unit 46 includes an image processing unit 60 and a signal processing unit 62.

Are portions that perform predetermined image processing on an image (image data) read by the scanner 12 in accordance with an image processing condition set by a condition setting unit 48 described later in detail. Both perform basically the same processing except that the pixel densities of the image data to be processed are different.

The image processing in the processing sections 50 and 60 includes basic processing such as gray balance adjustment (color balance adjustment), contrast correction (gradation processing), and brightness correction, as well as image state ( Image data read by the scanner 12), geometric distortion correction, density unevenness correction (peripheral light amount correction), sharpness (sharpening) processing, dodging processing, special Finishing (cross filter processing, soft focus finishing, black and white finishing, sepia finishing, etc.), emphasis / blur processing, face area processing (density,
(Skin color, emphasis / blur, etc.), red-eye correction, partial shape and color processing / correction of eyes, hair, lips, etc. One or more of processing, electronic scaling processing in combining images (different images and characters) and characters, trimming, and the like are exemplified.

Each of these corrections may be performed by a known method, and is performed by appropriately combining image processing operation, processing using an LUT (look-up table), matrix operation, processing using a filter, and the like. For example, gray balance adjustment, brightness correction, and contrast correction can be used for highlight (lowest density), shadow (highest density),
A method using a correction (adjustment) table created according to an image feature amount such as an average density is exemplified. Note that these correction tables are usually created for each of R, G, and B colors. Further, the gray balance adjustment LUT and the gradation correction LUT may be created by accumulating image data of one film F. In the sharpness processing, an image obtained by averaging the original image (first averaged image) and an image obtained by further averaging the first averaged image are created, and a difference between the two is multiplied by a sharpness correction coefficient to obtain an image. A method of adding the first averaged image to the obtained image is exemplified. In the dodging process, a blurred image (data) is generated by a filtering process using a luminance signal obtained by converting image data, an IIR filter, or the like, and an LUT or an arithmetic expression is created using the blurred image. A method of compressing / expanding a high-density area and a low-density area using processed image data to compress / extend the dynamic range of the original image while maintaining the intermediate gradation, thereby giving a dodging effect. (Examples of JP-A 9-1
8704 and 9-182093, Japanese Patent Application No. 9
-207941). The geometric distortion correction and the peripheral light amount correction are mainly for correcting the image distortion and the light amount decrease in the peripheral portion of the image when photographed by an inexpensive camera such as a film with a lens. Since the displacement of the pixel position and the decrease in the amount of light due to this distortion can be represented by a functional expression, a method of creating this functional expression and correcting the pixel position so that each pixel is at an appropriate position using this functional expression, and A method of performing density correction for the peripheral light amount reduction is exemplified. This function formula is usually created for each of R, G, and B colors. Further, as a method of correcting the scratch on the film, a method of designating an unnecessary area such as a scratch by a monitor test and replacing the image data of the unnecessary area with the background image data around the unnecessary area is exemplified. (See Japanese Patent Application No. 9-69366).

The signal processing unit 52 of the prescan image processing unit 44 converts the image data processed by the processing unit 50 into
This is a part that is converted using an LUT or the like to make image data corresponding to display on the display 20. On the other hand, the signal processing unit 62 of the main scan image processing unit 46 is
Image data (output image data) processed by
A part that converts the image data into image data corresponding to image recording by the printer 16 and supplies the image data to the printer 16. As will be described in detail later, the printer 16 scans and exposes a photosensitive material (photographic paper) with a light beam modulated according to the image data to form a latent image, performs a predetermined developing process, and outputs the print. . Processing conditions such as an image data conversion table set in the signal processing unit 62 may be stored as image processing conditions.

Processing unit 5 of prescan image processing unit 44
0 and image processing and image processing conditions to be performed by the processing unit 60 of the main scan image processing unit 46 are set by the condition setting unit 48. The condition setting unit 48 includes an image processing condition setting unit 64, an identification information acquisition unit 66, a key correction unit 70, and a parameter integration unit 72. Further, the parameter integrating unit 72 stores identification information for identifying each frame of the film F on which a print has been previously prepared (usually at the time of simultaneous printing) and information on image processing of the frame in association with each other. Storage means 68 is connected.

The image processing condition setting unit 64 (hereinafter, setting unit 6)
4) according to the pre-scanned image, or the main part (region) extracted from the pre-scanned image, the instruction from the operator, and the like.
Using the image processing information stored in the storage unit 68, the image processing conditions for the display and output images in the processing units 50 and 60 are set and supplied to the parameter integration unit 72. Specifically, the setting unit 64 generates a density histogram from the pre-scan data, average density, highlight (lowest density) and shadow (highest density), LATD (large area transmission density), the maximum value and the minimum value of the histogram.

There is no particular limitation on the method of extracting the main part.
For example, a method of extracting the main part from the continuity of the image (color, shape, etc.) and a method of cutting out the main part using the mouse 18b or the like are exemplified. In addition, a known main part extraction algorithm may be used.
Patent Literature 1, a plurality of different main part extraction methods such as a method of extracting a specific color, a method of extracting a specific shape pattern, and a method of removing a region estimated to correspond to the background are weighted in advance. The main part is extracted by each extraction method, the extracted main part is weighted by the determined weight, the main part is determined and extracted according to the result, and other methods are disclosed in JP-A-4-346333. 5-158
No. 164, No. 5-165120, No. 6-160993
Nos. 8,184,925, 9-101579, 9-138471, etc., can be suitably used.

The key correction section 70 calculates the adjustment amount of the image processing condition in accordance with instructions such as color adjustment, density adjustment, and contrast (gradation) adjustment input from the keyboard 18a or the mouse 18b of the operation system 18. , And a parameter integration unit 72. For example, when a color adjustment is input from the operation system 18, a correction amount according to the input is calculated by the key correction unit 70, and a gray balance adjustment table is calculated by the parameter integration unit 72 in accordance with the correction amount. Is corrected, and when there is an input of density adjustment, the brightness correction table is similarly adjusted. When there is input of contrast adjustment, the contrast correction table is similarly adjusted.

The parameter integration section 72 receives the image processing conditions set by the setting section 64 and sends the supplied image processing conditions to the processing section 50 of the pre-scan image processing section 44 and the processing section 60 of the main scan image processing section 46. The image processing conditions set for each part are adjusted according to the adjustment amount calculated by the key correction unit 70 and the like. In addition, the parameter integration unit 72 determines the identification information of each frame acquired by the identification information acquisition unit 66 during simultaneous printing (or when there is no instruction for reprinting), and performs image processing of this frame. Is transmitted to the storage means 68, and at the time of reprinting, the information of the image processing of the frame is read out from the storage means 68 in accordance with the identification information acquired by the identification information acquisition section 66.

The identification information acquisition section 66 is a section for acquiring identification information for identifying a frame to be printed at the time of printing, and sending the identification information to the parameter integration section 72. In order to identify each frame of the film F, a means for determining the main body of the film F and information on the frame number of each frame of the film are required. The identification information is, for example, identification information (identification) of the main body of the film F. Number, identification ID, identification code, etc.) and a frame number. The identification information may be unique to the frame, that is, the print (the image) to be output, regardless of the film. Identification information acquisition unit 66
Obtains the identification information by various methods according to the type of film, the management system of the laboratory, and the like at the time of previous printing and reprinting.

For example, when the film F is a film (cartridge) of the above-mentioned new photographic system, the ID number of the cartridge and the frame number of each frame are recorded as magnetic information on the magnetic recording medium of the film. Using the ID number of the cartridge as the identification number of the film, the identification information acquisition unit 66 reads the magnetic information read and transferred by the scanner 12 (the carrier attached to the scanner 12),
Obtain the identification information of the frame to be printed. Since the ID number of the cartridge is usually written on the cartridge, the operator looks at the ID number and inputs the ID number and the frame number of the cartridge requested to be reprinted using the keyboard 18a or the like. Is also good.

In cases other than the new photographic system, at the time of simultaneous printing (development of the film F and creation of the print), etc., the date and time of printing, the customer, the developing machine that developed the film, the DX code and the extended DX code Of the film F according to the information of the film F
(Outside the image area) or recorded in a bag or case storing the film F, and the identification information acquisition section is input by the operator by using the keyboard 18a or the like by the operator to input the identification information of the film F during simultaneous printing or reprinting. 66 may obtain the identification information. The identification information is not directly written on the film F, the bag, or the like, but may be affixed with a label recording the identification information, or a bar code indicating the identification information of the film F may be affixed, The identification information of the film F may be read by a barcode reader. Further, the identification information of the film F, a bar code indicating the identification information, or the like may be optically recorded on the film F before development, and may be converted into a visible image by development. At this time, when the film F returned to the customer is cut into negative pieces such as 4 to 6 frames, it is preferable to record identification information and the like for each negative piece. These methods can also be used in the new photo system, and the determined identification information may be magnetically recorded and used instead of the cartridge ID.

The identification information may be recorded on the back side of the print together with the back print (reverse print) usually recorded on the print, or may be recorded inside or outside the image area of the print. Alternatively, the identification information of each frame may be recorded on the index print. The identification information may be converted into a barcode as in the previous example. In the case of a new photo system, a cartridge ID or a frame number recorded on an index print may be used as identification information. At this time, the operator inputs the identification information of the film F using the keyboard 18a or a barcode reader at the time of simultaneous printing or reprinting, so that the identification information acquiring unit 66 may acquire the identification information. .

The determination of the identification information (including the barcode) and the assignment to the film F or the like may be automatically performed. For example, when the film F is mounted on the scanner 12 (carrier), the identification information is automatically determined by the processing device 14 and the identification information acquisition unit 6
6 and a means for creating and attaching a label in which identification information is described is provided, and the label is attached to the film F that has been read (printed). Also,
When developing the film F, the control unit of the film developing machine (film processor) automatically determines the identification information and optically prints the identification information on an area other than the image area of the film F (for example, an unused area at the leading end or end). Alternatively, a label preparation and sticking means is provided, and a label containing identification information is stuck to the film after development.

Further, when the identification information is given to the film or the like in a state where the information can be read optically, the scanner 12 (carrier) or the like automatically performs the optical printing at the time of simultaneous printing or reprinting. The reading may be performed, and the identification information income unit 66 may automatically acquire the identification information. In addition, this reading may use bar code reading means such as a DX code usually arranged on the carrier.

In addition, a lab contractor (lab store) stores a customer ID
If the date of simultaneous print request, the number of processed data, and the like are managed, the main body of the film F can be specified from these combinations.

Alternatively, in a (digital) photo printer, image data of an image can be stored as a file on a recording medium such as a floppy disk.
This image file name may be used as identification information.

In any case, since the frame number is recorded in each frame when the film is manufactured,
You can use it, or instead of the frame number,
A barcode, a DX code, an extended DX code, or the like, which is optically recorded on the film F, may be used. The identification information acquisition unit 66 reads the barcode recorded on the film F by counting the scanner 12 (carrier). The frame number may be obtained by input from the operator.

The storage means 68 stores the above-described identification information of the frame of the film F and information of image processing of this frame in association with each other. The image processing information to be stored is information on image processing for reproducing the same image processing as that of the previous print at the time of reprinting, and includes, for example, the type of image processing performed, the order of image processing, and the image processing conditions. Alternatively, it is a parameter or related data for reproducing this.

As the image processing conditions or parameters and related data for reproducing the same, various types of information that can reproduce the preceding image processing (conditions) according to the image processing to be performed,
Specifically, the LUT created for the image processing, the processing equation, the coefficient applied to the predetermined image processing equation, the information of the image-processed area, the synthesized image or character data file, etc. Is exemplified.

More specifically, for example, for the gray balance adjustment, the brightness correction and the contrast correction, as described above, an LUT for correcting these is created, and this LUT
The correction and adjustment are performed according to the LUT
(For each color of R, G and B) is stored. Note that, as described above, the gray balance adjustment LUT and the gradation correction LU
When T is created from image data for one film F, this may be stored as information common to all frames of the target film F. In the sharpness processing, the above-described sharpness correction coefficient is stored. Also in the dodging process, the LUT and the processing operation are set, the image data is processed, and the dynamic range is compressed / processed using the image data obtained by the processing. Therefore, the LUT or the processing operation is stored. In the geometric distortion correction and the peripheral light amount correction, since a correction is performed by creating a function formula indicating a pixel position shift and a decrease in the light amount, the function formula is stored. When a function formula is created for each color, each is stored. Further, since this function formula is the same for all the frames of one film F, it may be stored as information of the film F. Alternatively, instead of these functional expressions, a correction (two-dimensional) table indicating a pixel position shift or a decrease in light amount may be created and stored. When the scratch on the film is corrected, the position of the specified scratch and the background pixel data replaced with the scratch (part of it)
Is stored. Furthermore, when images and characters such as characters and other images are combined, the file name and combining position of the combined characters and images are modified when the face area is processed or partially modified. Area and color / density and shape correction data, the aspect ratio is changed when the aspect ratio is changed, the scaling factor is set when the trimming is performed, and Parameters according to the processing,
Remember each.

Further, as described above, the processing device 14 extracts the main area such as the face area as necessary and sets the image processing conditions. Therefore, when the processing apparatus 14 corrects only the face area, for example, And the like, information on the face area is also stored.

The storage means 68 for storing identification information and image processing information is not particularly limited, and various means can be used. For example, when the film F is of a new photographic system, a magnetic recording medium formed on the film F may be used as the storage unit 68. However, since the storage capacity of the magnetic recording medium formed on the film F is limited, it is necessary to consider that a large amount of information cannot be stored when utilizing this. Further, a recording medium such as a floppy disk, a magneto-optical recording medium, or an IC card may be used as the storage means 68. In this case, the recording medium is delivered to the customer together with the print, and the recording medium is supplied from the customer together with the film F at the time of reprinting, and is read by a drive or the like connected to the photo printer 10. If your lab has a customer database,
This database may be used as the storage means 68. In addition,
If such information is permanently stored, the amount of information becomes enormous. Therefore, it is preferable that the storage be performed for a predetermined period determined as appropriate. For example, since a reprint request is generally made within one month from simultaneous printing, the storage period may be about one month after simultaneous printing. Alternatively, the processing device 14 or a personal computer owned by a lab operator is connected to a LAN or a WAN (Wide Area Network).
When a request for reprinting of the film F is received by connecting to a communication means such as a computer communication network such as that described above, the information of image processing is obtained by accessing a database of another lab vendor that has performed the previous printing. Alternatively, a personal computer owned by the customer may be used as the storage unit 68 to store identification information and image processing information at the time of simultaneous printing or the like, and may be accessed at the time of reprinting to obtain image processing information. .

As described above, when an image or character such as a character or another image is synthesized, if the image or character data (hereinafter referred to as reference data) is unique to the customer, The reference data itself may be recorded on a recording medium to be passed to the customer or on the customer's personal computer. Alternatively, when the amount of information of the reference data is larger than a predetermined amount, the reference data itself is stored in a database of a laboratory for a certain period of time, and the file name of the reference data and information of an access destination are recorded on a recording medium or the like which is passed to a customer. May be. Furthermore, when the reference data is general-purpose such as when the reference data is quoted from a specific pattern or some database, the file name of the reference data and the information of the access destination are provided to the customer. The information may be recorded on a recording medium to be passed.

As described above, when print image data is stored as a file on a recording medium such as a floppy disk, identification information and image processing information may be added as data attached to the image file.

As described above, the image data processed by the processing device 14 is sent to the printer 16. FIG. 3 shows a schematic diagram of the printer 16. The printer 16 includes a driver 80, an exposure unit 82, and a development unit 84. The printer 16 modulates, for example, a pulse width of the light beam L in accordance with the image data sent from the processing unit 14, and
Is exposed.

The image data from the processing device 14 is sent to the driver 80. The driver 80 converts the image data sent from the processing device 14 (signal processing unit 62) into a drive signal of the pulse width modulation of the AOM 86 corresponding to the recorded image (exposure amount), and drives each AOM 86. .

The exposure section 82 scans and exposes the photosensitive material A by light beam scanning and records the image of the image data on the photosensitive material A. As shown conceptually in FIG. A light source 88R for emitting a light beam in a narrow band corresponding to the exposure of the R photosensitive layer formed in the above, a light source 88G corresponding to the exposure of the G photosensitive layer, and a light source corresponding to the exposure of the B photosensitive layer 88B light source for each light beam,
AOMs 86R, 86G and 86B for modulating the light beams emitted from each light source in accordance with the recorded image, a polygon mirror 90 as an optical deflector, and an fθ lens 92
And a sub-scanning conveyance unit for the photosensitive material A.

The light beams emitted from the light sources 88 (88R, 88G, 88B) and traveling at different angles from each other are respectively AOM 86 (86R, 86G,
86B). Each AOM 86 has a driver 80
R, G, and B drive signals corresponding to the recorded image, that is, the image data supplied from the image processing device 74 are transferred, and modulate the incident light beam according to the recorded image.

Each light beam modulated by the AOM 86 is incident on substantially the same point of the polygon mirror 90, reflected, deflected in the main scanning direction (the direction of the arrow x in the drawing), and then by the fθ lens 92 at a predetermined scanning position. It is adjusted so as to form an image with a predetermined beam shape at z, and enters the photosensitive material A. The exposure unit 82 may be provided with a light beam shaping unit and a surface tilt correction optical system as necessary.

On the other hand, the photosensitive material A is long and is loaded at a predetermined position in a state of being wound into a roll and formed into a magazine. Such a photosensitive material A is pulled out by a draw-out roller, cut by a cutter into a predetermined length corresponding to one print, and is transported by a pair of transport rollers 94a and 94b constituting a sub-scanning means arranged with a scanning position z therebetween. While being held at the scanning position z, the sheet is transported in the sub-scanning direction (the direction of the arrow y in the drawing) orthogonal to the main scanning direction. Also,
On the way, necessary information is backprinted. As this back print, the frame, that is, print (image)
May be recorded as described above. Since the light beam is deflected in the main scanning direction, the entire surface of the photosensitive material A transported in the sub-scanning direction is two-dimensionally scanned and exposed by the light beam, and the photosensitive material A is applied to the processing apparatus 1.
4 is recorded with the image (latent image) of the image data transferred from.

The exposed photosensitive material A is then conveyed to the developing section 84 by the pair of conveying rollers 96, where it is subjected to a developing process to be a finished print P. Here, for example, if the photosensitive material A is a silver salt photosensitive material, the developing unit 84 includes a color developing tank 98, a bleach-fixing tank 100, and washing tanks 102a and 102.
b, 102c and 102d, a drying section, a cutter (not shown), and the like. The photosensitive material A is processed in each processing tank, dried, and output as a print P.

Hereinafter, the printing system of the present invention will be described in more detail by describing the operation of the photo printer 10.

First, an example of so-called simultaneous printing will be described. At the time of simultaneous printing, a carrier corresponding to the film F is mounted at a predetermined position of the scanner 12 and the film F is set at a predetermined position of the carrier.
The first frame, usually the frame of frame number 1, is conveyed to a predetermined reading position by the carrier.

Here, when the film F to be read (printed) is a film of a new photographic system, the magnetic information recorded on the film F is read by the carrier when the film F is transported. Then, necessary information is sent to the processing device 14, and the cartridge ID number is sent to the identification information acquisition unit 66 as the identification number of the film F. On the other hand, in the case of a normal 135-size negative film or the like, as an example, before mounting the film F on a carrier, an identification number for an operator to identify the film F main body according to a date, a customer, or the like, for example. And determine
The label on which the identification number is described is stuck outside the image area of the film F, and the set identification number is input by the keyboard 18a. With this input, the identification number of the film F to be used for print creation is sent to the identification information acquisition unit 66. As described above, the determination of the identification number, the assignment to the film F, the reading, and the transfer to the identification information acquisition unit 66 may be automatically performed as described above.

Thereafter, the scanner 1 determines the light amount of the light source 22, the open value of the variable aperture 24, the rising of the CCD sensor 34, and the like.
When it is confirmed that 2 is in the predetermined state, reading is started. In other words, the reading light emitted from the light source 22, adjusted by the variable aperture 24 and the color filter plate 26, and diffused by the diffusion box 28
Projection light that enters and transmits the frame and carries an image captured on this frame is transmitted by the imaging lens unit 32 to the CC.
An image is formed on the D sensor 34, photoelectrically converted, amplified by the amplifier 36, and sent to the processing device 14.

As described above, in the scanner 12,
By performing such image reading three times by sequentially inserting the respective color filters of the color filter plate 26, the film F
Are sequentially decomposed into three primary colors of R, G and B. Further, prior to the main scan for obtaining an output image, a pre-scan for reading the image at a low pixel density is performed, and thus a total of six readings are performed for one frame, as described above. .

When the image reading of the first frame is completed, the carrier transports the film F by one frame, the second frame is transported to the reading position, and the pre-scan and the main scan are performed in the same manner to read the image. Then, the image data is sent to the processing device 14, and then the third frame is conveyed and read in the same manner. Thereafter, similarly, the image of each frame is sequentially read, and the image data is sent to the processing device 14. Can be In addition to the image data, information on the frame number of the read image, that is, the frame number of the read image (image data) is also sent to the processing device 14 (identification information acquisition unit 66). . The frame number may be determined by the read count from the first frame, or may be determined by reading a bar code recorded on the film F. When the film F is a new photographic system, It can also be determined from magnetic information.

The image data output from the scanner 12 is A / D-converted and Log-converted by the data converter 38 into digital image data, and then subjected to predetermined processing such as offset correction in the data processor 54. The pre-scan data of R, G and B are sequentially transferred and stored in the pre-scan memory 40, and similarly, the main scan data is transferred and stored in the main scan memory 42.

When the pre-scan data is stored in the pre-scan memory 40, the setting section 64 reads out the pre-scan data, creates a histogram and calculates the image feature amount, as described above, and furthermore, performs the operation of the main part such as the face. Extraction is performed, and based on the result, the reading conditions of the main scan such as the aperture value of the variable aperture 24 are set, and the image processing to be executed is selected.
The order is determined, and image processing conditions for each image processing are set. The set image processing conditions are sent to the parameter integration unit 72 and set in the processing unit 50 of the pre-scan image processing unit 44 and the processing unit 60 of the main scan image processing unit 46. The main scan is performed after the reading conditions are set, and the R, G, and B main scan data are sequentially transferred and stored in the main scan memory 42.

When the image processing conditions are set in the processing unit 50, the pre-scan data is read from the pre-scan memory 40, and the processing unit 50 performs image processing according to the set image processing conditions. This image data is then supplied to the signal processing unit 52 and converted into image data according to the display on the display 20, and the prescan image is displayed on the display 20.

The operator confirms (verifies) the image, that is, the processing result, by viewing the display on the display 20, and adjusts the color / density, gradation, etc., using the keyboard 18a and the mouse 18b as necessary. And processing such as synthesis processing and partial correction. The adjustment signal is sent to the key correction unit 70
The key correction unit 70 calculates the correction amount of the image processing condition according to the input, and sends it to the parameter integration unit 72. The parameter integration unit 72 corrects the image processing conditions set in the processing unit 50 and the processing unit 60 as described above, according to the correction amount sent. Therefore, the image displayed on the display 20 changes according to the input by the operator.

When the operator determines that the image displayed on the display 20 is proper (OK), the operator instructs the start of printing using the keyboard 18a or the like. As a result, the image processing conditions are determined, the main scan data is read from the main scan memory 42, processed in the processing unit 60 of the main scan image processing unit 46 under the determined conditions, and the printer 16 The image data is converted into image data corresponding to the image recording by the printer 16 and sent to the driver 80 of the printer 16. At the same time, the parameter integration unit 72
Receives the frame number and the film identification number, that is, the identification information of the frame, from the identification information acquisition unit 66, and information of the image processing corresponding to the determined image processing condition, specifically,
Image processing information such as image processing to be executed and its order, image processing parameters and LUTs, image processing application range data, information on related image data, and the like, and frame identification information are associated with each other, and both are stored in the storage unit 68 To be stored.

In this example, although the verification is performed by the operator, the verification is not performed, and the image processing conditions set by the setting unit 64 are processed by the parameter integration unit 72 by the processing unit 60.
The image processing conditions may be settled at the time of setting, and similarly, the start of printing and the transfer of the image processing information and the frame identification information to the storage unit 68 may be performed. It is preferable that the presence or absence of such a test can be selected as a mode.

The image data is transferred to the driver 80 of the printer 16.
Is sent to the AO by the driver 80 as described above.
The light beam modulated by driving the M86 and deflected in the main scanning direction by the polygon mirror 90 is cut into a predetermined length corresponding to the print, and the photosensitive material A conveyed in the sub-scanning direction by the conveying roller pair 94 is two-dimensionally moved. A latent image is formed by scanning exposure, and the exposed photosensitive material A is subjected to processing such as color development, bleach-fixing, washing with water, and drying in the developing section 16 and output as a print P.

In the printing system of the present invention, the information stored in the storage means 68 is not limited to the information of the image processing at the time of the simultaneous printing. When reprinting is requested by requesting a new print, or when reprinting a frame for which image processing information is not stored, the image processing conditions determined at this time should be saved as image processing information for the previous print. You may. In the following description, the simultaneous printing is described as the preceding printing.

On the other hand, in the photo printer 10, reprinting is basically performed as follows. When the operator inputs an instruction to reprint,
Scanner 1 for the carrier corresponding to the requested film F
2, the film F is mounted on the carrier, and a frame to be reprinted is designated using the keyboard 18a or the like. Thereby, the carrier transports the film F, and the frame to be reprinted is transported to the reading position.

Here, when the film F is a film of the new photographic system, the carrier reads the magnetic information recorded on the magnetic recording medium of the film F by this conveyance, and the necessary information is sent to the processor 14. The identification information acquiring unit 66 acquires the identification information of the frame to be reprinted, that is, the identification number of the film F (the ID number of the cartridge) and the frame number of the frame transported to the reading position. On the other hand, when the film F is a normal 135-size negative film or the like, the operator looks at the description of the film F and the attached label as described above, and inputs the information using the keyboard 18a or the like. The identification information acquisition section 66 acquires the identification number of the film, and acquires the frame number according to the instruction of the frame to be reprinted by the operator. Alternatively, as described above, the acquisition of the identification numbers of the film F by automatically reading the identification numbers of the labels or the reading of the frame numbers by reading the barcodes of the film may be performed by the identification information acquisition unit 66 to automate the acquisition. It is possible.

Next, as in the case of simultaneous printing, after the scanner 12 is confirmed to be in the predetermined state, reading is started, pre-scan and main scan are performed, and image data is sequentially stored in the pre-scan memory. And sent to the main scan memory and stored. On the other hand, the parameter integration unit 72 receives the identification information of the frame to be reprinted from the identification information acquisition unit 66, reads out the image processing information corresponding to this identification information from the storage unit 68, and
Send to The setting unit 64 determines the reading conditions of the main scan in the same manner as described above, and uses the information of the image processing read from the storage unit 68 to set the image processing to be performed and the order of the image processing to be the same as in the case of simultaneous printing. Determined, and, if necessary, by using the pre-scan image data, reproduce the image processing conditions of the image processing performed at the time of simultaneous printing,
This is set in the parameter integration unit 72. Further, when there is related data such as a combination of characters and images, the parameter integration unit 72 accesses the corresponding image data file and acquires necessary data.

The parameter integration section 72 sets the image processing conditions (or related data) in the processing section 60 of the main scan image processing section 46. In the case of reprinting, basically, the image processing conditions are determined by this, the main scan data is read from the main scan memory 42, processed by the processing unit 60 under the determined conditions, and processed by the signal processing unit 62. Are converted by the driver 80 of the printer 16.
The print P is output in the same manner. In this case, it is not always necessary to display the pre-scanned image on the display 20. Further, the image processing conditions may be corrected as necessary, such as receiving an instruction to correct the image at the time of requesting the reprint, or the verification may be performed similarly to the simultaneous printing. Here, the image reproduced by this reprint is an image that has been subjected to the same image processing and the same image processing conditions as in the simultaneous printing,
This is an image in which the color and density suitably match the image of the simultaneous printing. In addition, since the image processing conditions are set using the information of the image processing of the previous print, when reprinting,
It is possible to quickly set image processing conditions. Especially,
LU for gray balance adjustment and gradation correction during simultaneous printing
When T is created using the accumulated image data of one film F, it is necessary to read the image of one film F again in the conventional method. Although the work is extremely laborious and time-consuming because of the division, according to the present invention, this can be omitted, and the work time and labor of the work can be largely saved. Further, at the time of reprinting, extraction of a main part such as a face can be omitted, which is also advantageous in this respect.

In the above example, only the information of the image processing is stored in the storage means 68. However, the present invention is not limited to this, and various other information may be stored in the frame. The image processing information may be stored in the storage unit 68 together with the image processing information in association with the identification information, and the image processing may be performed using the information.
This makes it possible to more reliably create a reprint in which an image of the same color and density as the image of the simultaneous (previous) print is reproduced.

For example, in the photo printer 10, the scanner 12 uses the CCD sensor 34 to project the light projected on the film.
The image of each frame photographed on the film is read by photoelectric conversion. Here, the light amount of the light source 22 and the sensitivity of the CCD sensor 34 are not always constant,
It changes over time. Therefore, for example, even if an image of the same frame is read by the same device in simultaneous printing and reprinting, the image data output from the scanner 12 may not always match. Scanner 1
2 has a machine difference, and when reading is performed by different scanners 12 for simultaneous printing and reprinting,
Even if the image of the same frame is read, the output image data may not always match.

Therefore, in the print system of the present invention, the image feature amount of the input image data (pre-scan data and / or main scan data) is stored in the storage means 68 together with the information on the image processing for simultaneous printing. The image feature amount calculated at the time of reprinting may be compared with the image feature amount of the simultaneous printing, and image processing may be performed after correcting the image data of the main scan with reference to the image feature amount.

Specifically, as described above, the setting unit 64
Calculates an image feature amount from a pre-scan image in order to set image processing conditions and the like. In this embodiment, the image feature amount calculated at the time of simultaneous printing, for example, the average value of image density, highlight and shadow, histogram shape (for example, density value of maximum value and minimum value), and image are divided into blocks. The histogram shape etc. of each block,
Preferably, each of R, G and B is stored in the storage means 68 together with the information of the image processing described above. At the time of reprinting, the image feature amount calculated at the time of simultaneous printing is read together with the image processing information, and the image feature amount calculated from the prescan data for reprinting is compared. A correction condition is set such that the feature amount matches the image feature amount of simultaneous printing. As this correction, for example, an overall density shift and correction using a gradation correction curve (LUT) are exemplified. As aforementioned,
When the image processing conditions for reprinting are determined, the actual scan data (input image data) from the actual scan memory 42
Is read out, and the main scan data is corrected according to the correction conditions before the processing by the processing unit 60. Thereafter, the processing unit 60 performs image processing.

Further, at least one of input image data, a reduced image of the input image data, image data having a reduced resolution (space and / or density) of the input image, data obtained by compressing (encoding) the input image data, and the like. May be stored in the storage unit 68 together with the information of the image processing described above. In this embodiment, the stored pre-scan data and the like may be used for setting correction conditions for matching the main scan data at the time of simultaneous printing and at the time of reprinting in the same manner as the above-described image feature amount. For example, the image feature amount is calculated from the stored image data (or the compressed and decoded image data). Alternatively, when the main scan data is stored, the main scan reading at the time of reprinting is not performed, and when the reprint instruction and the identification information of the frame are obtained, the main scan data at the time of simultaneous printing is obtained from the storage unit 68. Alternatively, image processing conditions may be read out, image processing conditions may be set, and image data for output may be created by processing the read-out main scan data during simultaneous printing using the conditions. In addition, the compressed main scan data is decoded, or the reduced main scan data is enlarged, or the resolution of the reduced main scan data is converted (increased) to obtain the same as the main scan data itself. May be performed.

In the above example, the image feature values before the image processing are stored, and the image processing is performed after the correction so that the image feature values in the simultaneous printing and the reprinting coincide with each other. In addition, the present invention also stores the image feature amount of the image (image data) processed by the processing unit 60 in the storage unit 68 together with the information of the image processing at the time of simultaneous printing, The image feature amount of the image processed in step 60 is calculated, and the same correction is performed on the image data processed in the processing unit 60 so that the image feature amount in simultaneous printing and reprinting coincides with each other. You may.
Similarly to the input image data described above, the image data (hereinafter, referred to as output image data) itself, the reduced image of the output image data, the output image The storage means 68 may store low-resolution image data of data, compressed data of output image data, and the like. Reprints using these can be created by referring to the above-described image features and input image data.

According to these aspects, deviation of image data due to the state of the scanner 12 and the like are also preferably corrected,
More reliably, a reprint in which an image of the same color and density as the image of the simultaneous printing is reproduced can be created.
Therefore, such processing is unnecessary if the machine difference between the scanners 12 during simultaneous printing and reprinting can be ignored. Alternatively, reading conditions for simultaneous printing may be stored, and correction conditions for main scan data for correcting machine differences of the scanner 12 may be set based on the reading conditions for main scanning set during reprinting.

In the print system of the present invention, when input image data and output image data (or their compressed data) are stored, a film F (from a digital camera or the like) is used by using these image data. If the print is created, a reprint may be created without using the image data storage medium).

As a preferred example, the following embodiments are exemplified. In this embodiment, when creating a simultaneous print,
The input image data and image processing information are stored in the storage unit 68 in association with the frame identification information. The input image data to be stored may be only the main scan data, or may further store pre-scan data. The printer 16 records this identification information as a back print.

At the time of reprinting, the operator looks at the back of the print requested to be reprinted and inputs the recorded identification information using the keyboard 18a or the like. The processing device 14 obtains the identification information by this, and stores the identification information.
And reads out input image data and image processing information corresponding to the input identification information. Processing unit 14
Reproduces the image processing at the time of simultaneous printing from the information of the image processing in the same manner as described above. Here, if the customer gives an instruction to correct the image (so-called reprint), the operator adjusts the color and density of the image according to the instruction to correct the image processing conditions. In addition, when there is pre-scan data, the image is displayed on the display 20, or when there is no pre-scan data, the actual scan data is thinned out and displayed for verification, and image processing conditions are set. It may be corrected.

When the image processing conditions are reproduced, or the correction of the image processing conditions by the customer's request or verification is completed, and the setting of the image processing conditions to the predetermined part is completed (determination of the image processing conditions), the processing device 14 Processes the read main scan data of the input image data under the image processing conditions, and outputs the processed data to the printer 16 as image data corresponding to image recording by the printer 16. The printer 16 creates a reprint using the image data. Also at this time, identification information may be recorded as a back print.

In this example, both the information of the image processing and the input image data are stored in the storage means 68. However, in the case of simultaneous printing, it is possible to store only the input image data without storing the information of the image processing. Good. In this mode, at the time of reprinting, image processing conditions are set in the same manner as in simultaneous printing, using input image data (pre-scan data or thinned-out main scan data) read out according to the identification information. In accordance with the above, the image is corrected or verified in accordance with the instruction of the customer, the image processing conditions are determined, and the input image data of the main scan is processed under the determined image processing conditions.
The image data is output to the printer 16 as image data corresponding to image recording by the printer 16, and reprinted.
In this case, if the version of the image processing software is different or if image correction by the operator is performed during simultaneous printing, the image may be different between reprinting and simultaneous printing.

As another preferred mode, output image data may be stored. That is, at the time of simultaneous printing, the output image data and the identification information of the frame are stored in the storage unit 68 in association with each other. Note that the output image data to be stored may basically be only the main scan data.
Similarly, the printer 16 records the identification information on the print as a back print.

At the time of reprinting, the operator looks at the back of the print to be reprinted and inputs identification information using the keyboard 18a or the like. The processing device 14 acquires the identification information, searches the storage unit 68, and reads out the output image data corresponding to the input identification information. The processing device 14 processes the output image data in the signal processing unit 62, and outputs the image data to the printer 16 as image data corresponding to image recording by the printer 16. When the customer instructs to correct the image, the operator corrects the image processing conditions according to the correction instruction in the same manner as described above. If necessary, the main scan data may be thinned out and displayed on the display 20 to perform the verification. In addition, when prescan data is provided, the test may be performed using the prescan data. The printer 16 creates a reprint using the image data. Also at this time, identification information may be recorded as a back print.

In the above example, the identification information is recorded in the back print of the print, and the identification information is input at the time of reprinting by using this, and the processing device 14 acquires the identification information. Using the items described in the index print as the identification information, the reprint instruction and the identification information may be input using the index print instead of the print. In addition to the print and the index print, the identification information of the print to be reprinted verbally or by a memo by the requester of the reprint may be found, and may be input using the keyboard 18a or the like.

As is clear from the above description,
The above examples include various types of devices such as an image reading apparatus that does not have a film F, reads an image of a reflective original, an imaging device such as a digital camera or a digital video camera, a communication unit such as a LAN, and a medium such as a memory card or an MO. The present invention can also be suitably applied to reprinting of a print using image data from an image data supply source.

In the photo printer 10, the photosensitive material A is exposed in the printer 16 by a light beam modulated in accordance with the image data output from the image processing section 14, and the exposed photosensitive material A is subjected to predetermined development. The print P is output after the processing. Therefore, even if the image data output by the image processing unit 14 is the same, the color / density of the output image will be different if the light beam output and wavelength of the printer 16, the development processing temperature, the concentration of the processing liquid, and the like change. . However, these conditions fluctuate over time or within a day. As a result, even if the same image data is output from the processing device 14 in simultaneous printing and reprinting, the color of the output image of the print P is not changed. / The concentration may be different.

Therefore, in the print system of the present invention, the machine difference of the printer 16 may be corrected using the image feature amount of the image reproduced in the simultaneous printing. That is, when outputting a simultaneous print, the print image (density) is measured, the image feature amount is calculated in the same manner as in the above-described example, and this is stored together with the above-described image processing information in the storage unit 68. To memorize it. Then, at the time of reprinting, the image feature amount of the simultaneous printing is read, and at the time of reprinting, the output image data from the image processing unit 14 (the image data processed by the signal processing unit 62 or the processing unit 60). The image of the print output from the printer 16 is predicted from the image data processed in (1), and the image feature amount (hereinafter, referred to as an expected image feature amount) is calculated. Next, the two image feature values are compared, a correction condition is set such that the expected image feature value matches the image feature value of the simultaneous printing, and the output image data is processed under the correction condition. Output to 80. Also,
The print measurement image data, its compressed data, reduced image data, and resolution reduction data may be stored and used in the same manner as the main scan data.

Therefore, according to this embodiment, the printer 16
Regardless of the state, the reprint in which the image of the same color and density as the image of the simultaneous printing is reproduced can be created more reliably. Such a process is unnecessary if the difference between the printers 16 during simultaneous printing and reprinting can be ignored. Alternatively, the state of the printer 16 at the time of simultaneous printing may be stored, and a correction condition for correcting a machine difference of the printer 16 may be set.

In this embodiment, as a correction method for matching the expected image feature with the image feature of simultaneous printing,
Similar to the above-described embodiment, examples include a shift in image density and a correction using a gradation correction curve. In a normal printer, the relationship between the supplied image data and the density of the print image can be grasped to some extent as the output characteristics of the printer. The output print P image may be predicted. Regarding this aspect, reference can be made to Japanese Patent Application No. 8-238176 by the present applicant.

In the above example, the applied image processing, image processing conditions, and the like are stored as image processing information.
Using this, the image processing at the time of simultaneous printing was reproduced and reprinted, but the present invention also uses various data as information for image processing, and the same image as that of simultaneous printing is used. The reproduced reprint can be output. For example, the difference between the input image data and the output image data at the time of simultaneous printing is preferably compressed as information for image processing and stored in the storage unit 68, and the difference is stored in the storage unit 68 at the time of reprinting. Read from 68,
The difference may be added to the image data read by the scanner 12 and processed by the data processing unit 54, and the difference may be output to the printer 16 as output image data.

When the image on the film F is read by the scanner 12, a reading area on the film is defined by a mask formed on a carrier or the like. Here, naturally, the size of the mask is smaller than the image size of each frame shot on the film, so if the image position with respect to the mask is shifted between simultaneous printing and reprinting, the reproduced image will be different. . Also, when performing trimming in which a part of an image is cut out, enlarged, and reproduced, if the image position with respect to the mask is shifted between simultaneous printing and reprinting, the reproduced image will be different. Therefore, in the printing system of the present invention, in order to correct the positional deviation of the input image data between the simultaneous printing and the reprinting, the position reference data is recorded together with the image processing information, and is used at the time of the reprinting. (See Japanese Patent Application No. 9-69366).

In the above example, the extraction of the main part area and the setting of the image processing conditions are performed using the pre-scan data. However, the present invention is not limited to this. These operations may be performed. However, extraction of a main part, setting of image processing conditions, and the like need not be performed using image data having a high pixel density, and the calculation time increases in proportion to the number of pixels. Therefore, considering efficiency etc.,
These operations are preferably performed using prescan data. Further, in the above example, the pre-scan is performed and the condition setting and the like are performed using the pre-scan data. However, the present invention is not limited to this, and the scanner 12 performs only the main scan and performs the main scan. The data may be thinned out to obtain low-pixel-density image data such as pre-scan data, and the main part may be extracted and image processing conditions may be set using this data.

As described above, the print system of the present invention not only outputs a print reproducing the image photographed on the film F, but also obtains an image pickup device such as a digital camera or a digital video camera, a floppy disk, or a photo CD. It is also possible to receive image data from an image data supply source such as a recording medium and output a print that reproduces the image.According to the present invention, even in such print creation, simultaneous printing and reprinting can be performed. At times, it is possible to output a print in which the color and density of the reproduced image match. Also in this case, the information of the image processing is the same as that of the image output of the film F, and various methods exemplified for the film F can be used for the identification information of the frame. Furthermore, as the identification information of the frame,
The signal output from the device can also be used.

As described above, when outputting a print reproducing the image supplied from the image data supply source, the processed image data may be returned to the customer together with the print, but the image data supplied from the customer may be provided. Returning the image data without processing (original) has the following advantages. That is, the content of the image processing (for example, blur processing,
Depending on the character / image composition, it may not be possible to return the processed image data to the original image data. Therefore, when reprinting, reproduce the image processing (including changes) for the original image. However, it is possible to respond to a later request from a customer for a change in image processing. Also, like images of characters and talent,
Since the result of synthesizing a copyrighted image becomes a problem if it is distributed as image data, it is preferable to limit only prints.

The print system of the present invention can be suitably used not only for a digital photo printer as shown in FIG. 1, but also for a conventional direct exposure (analog exposure) photo printer. As is well known, a direct-exposure photo printer forms an image on a photosensitive material by projecting light of an image photographed on a film, and exposes (prints) the photosensitive material with the projected light.
After forming a latent image, a predetermined development process is performed to obtain a print reproducing the image photographed on the film. Here, when exposing the photosensitive material with the projection light of the film, appropriate color filters of C (cyan), M (magenta) and Y (yellow) are provided in the optical path in order to reproduce an image suitable for printing. Then, the color of the image is adjusted by inserting the amount, and the density of the image is adjusted by adjusting the projection light amount by the aperture.
The insertion amount of each filter and the adjustment amount of the aperture are, for example,
The image photographed on the film is photoelectrically read to obtain image data (input image data), and the image characteristic amount such as LATD, highlight and shadow of the image is calculated and determined using the image characteristic amount.

When the print system of the present invention is used in a direct exposure photo printer, the amount of insertion of each filter and the amount of adjustment of the aperture at the time of simultaneous printing are stored in storage means as image processing information. At the time of reprinting, the information of this image processing is read out according to the frame identification information acquired in the same manner as in the above-described example, and the same exposure conditions as those for simultaneous printing are reproduced. I do. Alternatively, similarly to the above-described digital photo printer, input image data (itself, reduced image, compressed data, resolution reduction data), photometric data of the created print (itself, reduced image, compression data, resolution reduction data) and the like are stored. This may be used at the time of reprinting.

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