DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of a digital image reading apparatus that photoelectrically reads a document image, performs predetermined image processing, and outputs it as image data for recording.

[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 such as photographic paper by projecting light of the film onto the photosensitive material. The exposure is performed by so-called direct (analog) exposure in which the photosensitive material is surface-exposed with the projection light.

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 A digital photo printer that scans and exposes a photosensitive material with recording light modulated according to the image data, records an image (latent image), develops the image, and outputs it as a print (photograph) is used as image data for recording. It was put to practical use.

In a digital photo printer, a film is read photoelectrically, and color density correction is performed by signal processing to determine exposure conditions. Therefore, the operator does not need to determine the exposure conditions and adjust the filters and the like at the time of exposure.
Also, since the exposure time is constant according to the image size,
Efficient work can be performed. Moreover, it is possible to freely perform editing of a print image such as synthesis of a plurality of images, image division, etc., and various kinds of image processing such as color / density adjustment and contour emphasis, and output a print processed freely according to a use. be able to. In addition, since a print image is basically handled as image data, it is possible to supply not only a print output but also image data to a computer or the like, and further save the image data on a recording medium such as a floppy disk. You can keep it. Further, according to the digital photo printer, it is possible to output a print in which a higher quality image is reproduced in terms of resolution, color / density reproducibility, and the like as compared with the conventional direct exposure print.

[0005] Such a digital photo printer basically comprises a scanner (image reading device), an image processing device, and an image recording device (printer). The scanner obtains projection light carrying the captured image by inputting the reading light to the film, forms the projection light on an image sensor such as a CCD sensor, and photoelectrically converts the projection light into an image. The image is read frame by frame and sent to the image processing device as film image data (image data signal). The image processing apparatus sequentially receives the image data sent from the scanner, performs predetermined image processing, and sends the image data to a printer as output image data (exposure conditions) for image recording. The printer receives the image data output from the image processing apparatus, and for example, if the apparatus uses light beam scanning exposure, modulates the light beam according to the image data sent from the image processing apparatus and modulates the light beam in the main scanning direction. The photosensitive material (printing paper) is conveyed in a sub-scanning direction orthogonal to the main scanning direction, and is scanned and exposed (printed) by a light beam to form a latent image. Then, the image photographed on the film is output as a reproduced print.

In the case of performing additional printing or the like, image reading of all frames photographed on a film is rarely performed, and the frames requested to be additionally printed by a customer (a print requester) are sequentially read by a scanner. To perform image reading. For example, when the operator sets a film on the scanner, inputs a frame to be reprinted, and then issues an instruction to start printing, the scanner sequentially transports the frame for which reprinting has been instructed to a predetermined reading position, Image reading is performed sequentially.

However, these instructions may be incorrectly input for the frame to be read as long as the operator gives the instruction. In addition, the operator may set the film by himself or may set the wrong frame at the reading position. is there. In this case, after the image reading by the scanner is started, the device that continuously processes the image data read by the scanner with the image processing device and outputs the image data for recording, even when the image of the wrong frame is read, Since predetermined image processing is performed and output as image data for recording, unnecessary image data is output, or unnecessary output of prints and waste of working time cannot be avoided.

FIG. 1 is a block diagram showing an example of a digital photo printer using the image reading apparatus of the present invention. Digital photo printer 10 (hereinafter, photo printer 10)
) Photoelectrically reads an image photographed on a film such as a strip F in which a large number of images are photographed on a long film or a slide in which a reversal film is held on a frame, and this image is read. Is generated to produce a print P. Such a photo printer 10 includes a scanner 12 that is a reading device that photoelectrically reads an image photographed on a film, performs predetermined image processing on image data of the film read by the scanner 12, and outputs the image data for output. A control device 14 that outputs the image data and manages and controls the entire photo printer 10, and scans and exposes the photosensitive material A with a light beam modulated according to the image data output from the control device 14 to perform a development process. And a printer 16 which is a recording device that outputs the print P as a print P. Here, the scanner 12 and the control device 1
Reference numeral 4 denotes an input device, which constitutes the image reading apparatus of the present invention.

FIG. 2A is a schematic diagram of the scanner 12. The scanner 12 basically includes an optical frame 18, a light source unit 20, a carrier base 22, an imaging unit 24, a CCD sensor 26 as an area sensor, and a carrier base 2.
2 has various carriers such as a film carrier 28 which can be freely attached. In the scanner 12, the film is conveyed in the direction indicated by the arrow x by the film carrier 28 or the like mounted on the carrier base 22, each frame is sequentially stopped at the reading position Z, and light from the light source unit 20 is irradiated on the film. Then, the projection light carrying the image photographed on the film is obtained, and the projection light is
The image formed on the film 6 is photoelectrically converted by the CCD sensor 26 to obtain an image signal, whereby the image photographed on the film is read two-dimensionally as image data.

The light source unit 20 forms reading light for reading an image photographed on a film by separating the image into three primary colors of R (red), G (green) and B (blue), and entering the film. And the carrier base 22 of the optical frame 18
, A light source 30, a variable aperture 32, a color filter plate 34, and a diffusion box 36. As the light source 30, various known light sources that can emit a sufficient amount of reading light for image reading by the CCD sensor 26 can be used, and examples thereof include a halogen lamp, a xenon lamp, and a mercury lamp.

The variable stop 32 adjusts the amount of light from the light source 30. In the illustrated example, the variable stop 32 has a logarithmic curve drawn at the light-shielding portion and has two different amounts of light passing therethrough in a direction perpendicular to the optical axis L. By using an ND filter and coming into contact with and separating from each other in a direction perpendicular to the optical axis L, the amount of light from the light source 30 to the film is adjusted. The color filter plate 34 is
a disk-shaped member rotatable about a
It has three color filters of R, G filter 36G and B filter 36B, and a nest (neutral) 36N where nothing is arranged. By rotating, each color filter is inserted into the optical path at the time of image reading, and the film is inserted. The image photographed in the above is separated into three primary colors of R, G and B, and a hole 36N is inserted into the optical path when adjusting the frame position of the film F described later (position adjustment mode). The diffusion box 36 emits light from the light source 30, the amount of light is adjusted by the variable diaphragm 32, diffuses the reading light passing through the color filter, and changes the amount of reading light incident on the film to the optical axis L.
This is to make the surface orthogonal to the surface uniform without unevenness.

Above the light source section 20, a carrier base 2 is provided.
2 are arranged. The carrier base 22 is a part that mounts a carrier such as a film carrier 28 on the upper surface and holds the carrier at a predetermined position, and is fixed vertically to the optical frame 18. An opening (not shown) for passing light from the light source unit 20 is formed in a portion corresponding to the optical axis L in the carrier base 22. The opening is set so that the light from the light source unit 20 is sufficiently irradiated on the entire surface of the maximum image plane size (size) of the film that can be read by the CCD sensor 26.

On the upper surface of the carrier base 22, an arrow y perpendicular to an arrow x direction which is a direction from the near side to the optical frame 12 in the drawing, that is, a direction in which the film or the like is conveyed.
In the direction, guide rails 38 and 38 are formed, while
Grooves 40 and 40 are formed on the bottom surface of the carrier such as the film carrier 28 to engage with the guide rails 38. Each of the film carriers 28 and the like engages the grooves 40 with the guide rail 38 of the carrier base 22 and pushes in the direction of the arrow y until the end face abuts on the optical frame 18, whereby the directions of the arrows x and y Is defined, and is positioned and placed at a predetermined position on the carrier base 22, and conversely, can be removed from the carrier base 22 by pulling out. The means for mounting the carrier at a predetermined position on the carrier base 22 is not particularly limited to this method.

The film carrier 28 conveys a long film on which a large number of images have been photographed, so-called strips (sleeve) F, in the longitudinal direction thereof, and transfers each image (frame) photographed on the strips to the optical axis. L, that is, a reading position Z corresponding to the opening of the carrier base 22.
Are sequentially transported to be read. A guide groove 42 is formed on the upper surface of the film carrier 28 so as to extend from one end to the other in a transport direction indicated by an arrow x and at a position intersecting the optical axis L. The guide groove 42 is a groove having substantially the same width as the film. When the film is inserted into the guide groove 42, the film is conveyed with the longitudinal direction coinciding with the x direction. It is transported to the upper reading position Z. Therefore, the depth of the guide groove 42 is set so that the image surface (that is, the emulsion surface) of the film is at a predetermined position in the optical axis L direction (the depth of focus direction).

Further, at the reading position Z of the film carrier 28, an opening through which light from the light source unit 20 passes is formed. This opening is connected to the CC
It also serves as a mask for determining the size of the film image read by the D sensor 26. The opening formed in the film carrier 28 may have a size corresponding to the opening of the carrier base 22 so that a mask corresponding to films of various sizes can be exchanged to be mounted on the film carrier 28.

In the guide groove 42, a transport means 44 for the strips F, a pressure bonding unit 46, and a screen detection sensor 48 are arranged from upstream to downstream in the x direction. The transport means 44 is composed of a motor 44a and a transport roller 44b, and transports the strips F intermittently in the direction of the arrow x. The frame detection is performed by a screen detection sensor 48 for detecting a captured image or DX code. Stops when it has arrived at the reading position Z, and restarts the transport of the strips F when receiving a signal indicating the end of reading from the control device 14, and transports the next frame to the reading position Z. Crimping unit 4
Numeral 6 is used to rotate the pressing member 46b having an opening through which the projection light of the strips F passes around the rotation shaft 46a to press and release the strips F. By pressing the strips F (frames) into the guide grooves 42, the curl of the strips F is corrected, and the entire image is held at a predetermined position in the optical axis L direction.

On the upper surface of the film carrier 28,
A position adjusting means 50 for transporting the strips F one by one according to the fine adjustment of the position of the frame (image) at the reading position Z or the judgment of the operator is arranged. In the illustrated example, as shown in FIG. 2B, the position adjusting means 50 includes a fine adjustment key 50a for slightly moving the strips F in the direction of the arrow x, and slightly moving the strips F in the direction opposite to the direction of the arrow x. A fine adjustment key 50b, a frame advance key 50c for moving the strips F by one frame in the arrow x direction, and a frame return key 50d for moving the strips F by one frame in the direction opposite to the arrow x direction. When each key is pressed by an operator or the like, the transport means 44 is driven in accordance with the key to perform fine adjustment of the frame position at the reading position Z, frame advance, and the like.

The carrier used in the image forming apparatus 10 of the present invention is not limited to the film carrier 28 described above.
Various carriers can be used as long as an opening for transmitting light from the light source unit 20 is formed at the reading position and a groove for engaging with the guide rail 38 is formed. For example, a slide carrier that sequentially transports the slides supplied by the operator to the reading position, a new photo system (Advanced
(Photo System) cartridge is loaded, and a carrier for a new photo system that sequentially transports each frame of film to the reading position, a manual carrier for the operator to fix the film in a predetermined position, and an operator places the film at an arbitrary position. It may be a trimming carrier or the like that performs reading by scanning. In addition, an automatic carrier such as a slide carrier or a carrier for a new photographic system, which automatically conveys each frame of a film to a reading position, has the same adjusting means as the position adjusting means 50 of the film carrier 28. Is provided.

On the upper part of the optical frame 18, an image forming section 24 for forming an image of the projection light such as a film on the CCD sensor 26 is arranged. The imaging unit 24 includes a zoom lens unit 52 that enlarges / reduces projection light by a known zoom mechanism.
And a focus adjustment lens unit 54 for performing focus adjustment by a known means, and is vertically mounted on a surface plate 56 fixed to the optical frame 18.

In normal reading, the zoom lens unit 52 changes the optical magnification in accordance with the size of the original film, for example, if the film is a 135-size film, to reduce the size of the projection light. The maximum size that can be received by the CCD sensor 26 (ie, the size in which the required image area is inscribed on the light receiving surface of the CCD sensor 26)
To form an image on the CCD sensor 26. Further, when performing so-called trimming, in which an arbitrary position of an image photographed on a film is cut out and reproduced on a print P, a magnification is set to, for example, 0.4 to
By changing to 0.8, an image can be formed on the CCD sensor 26. On the other hand, if necessary, the focus adjustment lens unit 54 may be configured to use a TTL (Through The Lens) method.
Automatic focus adjustment (autofocus: AF) using the contrast of the image read by the CD sensor 26

Projection light from a film such as a film is imaged on a CCD sensor 26 by an image forming unit 24, read photoelectrically, and sent to the control unit 14. The imaging unit 24
A shutter used for dark current correction may be disposed between the CCD sensor 26 and the CCD sensor 26. In the scanner 12 that performs two-dimensional image reading, the CCD sensor 26 is an area sensor, for example, a CCD sensor having 1380 × 920 pixels. In the illustrated example, a CCD is used.
The sensor 26 is configured to be movable in the x direction and the y direction by an amount corresponding to a half pixel, whereby the number of read pixels can be apparently increased up to four times.

In the scanner 12, the image is read three times by sequentially inserting the three color filters of R, G and B of the color filter plate 34, so that one frame of image taken on a film such as a film can be read. The image is read after being separated into three primary colors of R, G and B. In the illustrated example, prior to a main scan for obtaining image data for recording to be output to the printer 16, a press for reading an image at a low resolution in order to determine an aperture value of the variable aperture 32, set image processing conditions, and the like. A can is performed. That is, the scanner 12 performs image reading (output of image data) six times in total per frame. When the image reading of one frame is completed, the carrier (or operator) feeds the film F, and the frame to be read next is conveyed to a predetermined reading position (frame feeding).

Also, a predetermined unit (1
Various instructions such as a frame (reading frame) for creating a print P in the case of additional printing and the number of prints of each frame with respect to (sorting) minutes are provided by, for example, the scanner 12 for this sorting.
Prior to the reading by the operator, the operator inputs using a keyboard 64, a mouse 66, and the like of the control device 14, which will be described later. The scanner 12 (carrier) responds to this instruction,
The film F is fed frame by frame, and the image reading of the frame instructed to be read is sequentially performed. It should be noted that the image reading is performed only once for a frame for forming a plurality of prints P.

The image data read by the CCD sensor 26 is amplified by an amplifier (Amplifier), converted into a digital signal by an A / D converter, and log-converted by a log-conversion look-up table (above, not shown). ) And sent to the control device 14.

The controller 14 sets (sets up) various image processing conditions from the image data obtained by the pre-scan, performs image processing on the image data of the main scan in accordance with the image processing conditions, and The pre-scan memory 58, the main scan memory 60, and the image processing device 6 serve as output image data for image recording.
And 2. The control device 14 controls and manages the entire photo printer 10 in addition to the image processing. The control device 14 instructs (sets) various conditions and processes, prints, number of prints, color / density correction, and the like. A keyboard 64 (see FIG. 3) for inputting instructions and a mouse 6

FIG. 1 mainly shows parts related to image processing. The control unit 14 also includes a CPU for controlling the overall operation of the photo printer 10 and various instructions and management, and a photo printer. A memory for storing data necessary for operating the entire apparatus 10, a means for determining an aperture value of the variable aperture 20 in the main scan, and the like are arranged. The keyboard 64, the mouse 66, the display 68, the scanner 12, the printer 16 and the like are connected to the CPU.
(CPU bus) for transferring image data, control signals, and the like.

The pre-scan memory 58 and the main scan memory 60 are memories for storing image data.
The pre-scan image data is stored in the pre-scan memory 58.
The main scan image data is sent to the main scan memory 60 and stored (stored).
Note that the control device 14 may perform various corrections such as DC offset correction, darkness correction, and shading correction on the image data as needed before storing the image data in both memories.

The image processing device 62 is configured by combining a CPU, a memory, various image processing circuits, and the like, and displays image data read by a CCD sensor on a display 68, sets image processing conditions, The image data of the main scan is subjected to image processing or the like, and is output to the printer 16 or the like as image data for recording.

Hereinafter, the configuration of the image reading apparatus of the present invention will be described in more detail together with the operation of the scanner 12 and the control device 14.

The scanner 12 and the controller 14 are in the position adjustment mode when the next frame to be read by the carrier 28 is conveyed to the reading position Z and image reading is started. That is, in the scanner 12, the hole 34 </ b> N of the color filter plate 34 is inserted in the optical path, and the reading light emitted from the light source 30 and adjusted in light amount by the variable aperture 32 (for example, set to the basic open value of the apparatus). Is
The light is incident on the strip F while being white, and the projected light is imaged on the light receiving surface of the CCD sensor 26 by the image forming unit 24.

In the position adjustment mode, the electronic shutter of the CCD sensor 26 is in an open state, and continuously outputs read image data (output signals). The image data is amplified, converted into a digital signal, log-converted, and sent to the pre-scan memory 58 as described above. The image processing device 62 includes a pre-scan memory 58
Is continuously read, and the image is displayed on the display 68. Here, since the reading light is white and the image data is continuously output from the CCD sensor 26, the display 68 displays a monochrome image of the image photographed on the frame at the reading position Z of the strips F. It is displayed in real time. That is, the scanner 12 is like a monochrome digital video camera.

The operator looks at the image displayed on the display 68 and, if necessary,
The position of the frame (image) at the reading position Z is adjusted using the position adjusting means 50 (frame position adjustment). As described above, since the scanner 12 is configured as a monochrome digital video camera, the image displayed on the display 68 moves according to the frame position adjustment. When it is determined that the frame position is appropriate, the operator operates the start key (START / ENT) of the keyboard 64 shown in detail in FIG.
ER) Press 64a.

When the start key 64a is pressed, the position adjustment mode ends, and pre-scan starts. When the pre-scan starts, the color filter plate 34 rotates,
For example, a G filter 34G is inserted into the optical path, the light amount is adjusted by the variable aperture 32, the light is adjusted by the G filter 34G, the light enters the first frame of the film F, is transmitted, and the image (G image ) Is obtained. This projection light is imaged on the CCD sensor 26 by the imaging unit 24, the G image of the film F is read, and sent to the pre-scan memory 58 and stored in the same manner as above.
When the reading of the G image is completed, the color filter plate 34 rotates, for example, a B filter 34B is inserted into the optical path to read the B image in the same manner, then the R image is read, and the pre-scan memory 58 is sequentially read. And the pre-scan ends.

When the pre-scan image data is stored in the pre-scan memory 58, the image processing device 62 reads out the pre-scan image data, creates a density histogram, calculates an image feature amount, and the like. The reading conditions in the main scan, such as the open value, are set, and image processing conditions such as color / density correction, electronic magnification, dynamic range processing conditions, and sharpness (sharpening processing) are set. Next, the image processing device 62 processes the prescanned image data according to the set image processing conditions, and displays the processed data on the display 68. On the other hand, when the reading conditions are set, the scanner 12 adjusts the variable aperture 32 and the like,
The main scan is performed in the same manner as the pre-scan described above, and similarly, the image data of the R, G, and B main scans of the images captured on the strips F are sequentially stored in the main scan memory 60.

The operator looks at the image displayed on the display 68 to perform verification, and adjusts the color / density of the image as necessary using the keyboard 64, the mouse 66, and the like. The previously set image processing conditions are corrected according to the adjustment by the operator, and the image displayed on the display 68 also changes. If it is determined that the image is appropriate (test OK), the operator re-enters the keyboard 6
4 start key 64a is pressed.

When the start key 64a is pressed, the image processing conditions are determined, and the image processing device 62 reads out the main scan image data from the main scan memory 60, and according to the determined image processing conditions, the image processing device 62 reads out the image data. After performing predetermined image processing such as color / density correction, magnification processing (electronic enlargement / reduction processing), dynamic range compression / expansion (imparting dodging effect by image processing), and sharpness, image recording by the printer 16 is performed. Is output to the driver 70 of the printer 16 as image data. When the start key 64a is pressed, the scanner 12 and the controller 14 enter the position adjustment mode, and the carrier 28 transports the next frame to be read to the reading position Z.

That is, the scanner 12 and the control device 1
In No. 4, in one sort of strips F or the like, "frame advance → position adjustment mode (frame position adjustment) → depression of start key 64a → prescan (main scan) → display on display 68 → verification → start key 64a Press → transfer of image data → frame advance ”routine is repeatedly performed.

Here, in the scanner 12 and the control device 14 according to the image reading apparatus of the present invention, the first start key 64a is pressed after the first start key 64a is pressed.
During the pressing, the scan cancellation of the keyboard 64 (SCA
N CANCEL) When any key of the key 64b or the position adjusting means 50 of the carrier 28 is pressed, the control device 14
Stops the image reading (pre-scan and main scan) at that time, and causes the scanner 12 and the control device 14 to
The position adjustment mode is a state in which reading is started.
That is, it is possible to cancel the scan performed on the frame, stop outputting the image data, and perform frame advance to read another frame (create a print) and readjust the frame position. With such a configuration, the image reading can be canceled by a simple operation. For example, even when an incorrect image is read at the time of additional printing or the like, extra image reading or unnecessary image data can be performed. Output can be prevented, and efficient work can be performed.

The photo printer 10 (scanner 12)
In addition, in the control device 14), in addition to the work mode in which the frame position can be adjusted by entering the above-described position adjustment mode, the image reading is automatically performed after the frame advance without entering the position adjustment mode, and the verification is performed. After start key 64a
Is pressed to output image data to the printer 16 (the start key 64a is depressed once), no operator operation is required, and after reading an image captured on a film, the image is output to the printer 16. A work mode in which the photo printer 10 automatically outputs data (without pressing the start key 64a) is also set, and the mode is selected before film reading is started. Regardless of which work mode is selected, the scan cancel key 64b or the position adjusting
When any one of the keys 0 is pressed, the scanner 12 and the controller 14 enter the position adjustment mode, and enter the operation mode in which the operation has been described in detail.

As described above, the image data output from the image processing device 62 (control device 14) is output to the printer 16. FIG. 4 is a schematic diagram of the printer 16. The printer 16 includes a driver 70, an exposure unit 72, and a developing unit 74. The image data output from the image processing device 14 is sent to the driver 70. The driver 70 D / A converts the image data into analog image data, and modulates the light beam according to the analog image data by using the acousto-optic modulator (A) of the exposure unit 72.

Each light beam emitted from each light source 78 and traveling at a different angle from each other is
The light enters M76. To each AOM 76, R, G, and B drive signals corresponding to a recorded image from the driver 70, that is, image data supplied from the image processing device 14, are transferred, and the incident light beam is changed according to the recorded image. Modulate.

Each light beam modulated by the AOM 76 enters the polygon mirror 80 at substantially the same point, is reflected, is deflected in the main scanning direction (the direction indicated by the arrow x in the drawing), and is then moved by the fθ lens 82 to 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 72 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. The photosensitive material A is pulled out by a pull-out roller (not shown), and is held in the scanning position z while being held at the scanning position z by a pair of conveying rollers 84a and 84b constituting a sub-scanning unit disposed with the scanning position z interposed therebetween. Are conveyed in the sub-scanning direction (the direction of the arrow y in the figure) orthogonal to. Since the light beam is deflected in the main scanning direction, the entire surface of the photosensitive material A conveyed in the sub-scanning direction is two-dimensionally scanned and exposed by the light beam and transferred from the image processing device 14 to the photosensitive material A. An image (latent image) of the image data is recorded.

The exposed photosensitive material A is then carried into the developing section 74 by the pair of conveying rollers 86, where it is subjected to a developing process to be a print P. Here, for example, if the photosensitive material A is a silver salt photosensitive material, the developing unit 74 is provided in the color developing tank 8.
8, comprising a bleach-fixing tank 90, washing tanks 92a, 92b, 92c and 92d, a drying unit and a cutter (not shown), and the like. , Is cut into a predetermined length corresponding to one print by a cutter, and is output as a print P.

In the image reading apparatus of the present invention,
A drive for recording and reading data on a magnetic recording medium such as a floppy disk or a recording medium such as an MO (optical timing recording medium) is connected to the control device 14 and processed by the image processing device 62 (or unprocessed). ) Image data may be output to these recording media.

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.

[0052]

As described above in detail, according to the image reading apparatus of the present invention, reading can be stopped even if an image (frame) to be read at the time of additional printing is erroneously read. Efficient work can be performed by preventing image reading and image data output.
