Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention performs a pre-scan and a main scan by relatively moving a line sensor for reading a frame image of a developed photographic film and the photographic film. In the main scan, the frame image is read at a low resolution for the purpose of printing, and in the main scan, the frame image is read in a high resolution, and image processing required for image data finally obtained by the main scan is performed. The present invention relates to a photographic film image processing apparatus that outputs print data by performing a printing process.
[0002]
[Prior art]
The function of a general photographic film image processing device is to read a frame image of a developed negative film, convert it to digital data, subject it to predetermined image processing, and then expose it to a photographic photosensitive material such as photographic paper using a digital exposure device. It is to be. At this time, a line sensor is used to convert the information of the frame image into digital data, and image data can be captured by relatively moving the negative film and the line sensor. In this case, reading (scanning) of the frame image by the line sensor is performed twice: a low-resolution pre-scan and a high-resolution main scan.
[0003]
The frame image read in the pre-scan is displayed on the monitor, and the operator looks at the displayed frame image and inputs color / density correction information as needed so that an appropriate print finish is obtained. Such a process is called a pre-judge work process. The main scan is for acquiring high-resolution image data used as print data, and the high-resolution image data acquired in this main scan is subjected to image processing based on correction information input in the pre-judge process, Output as print data.
[0004]
[Problems to be solved by the invention]
Such a photographic film image processing apparatus is disclosed, for example, in Japanese Patent Application Laid-Open No. 2001-42460, in which a digital exposure apparatus is used when correction information for all frame images has been input in a pre-judge work process. The main scan is performed to acquire high-resolution image data used as the exposure data of the image data. In the pre-scan, the entire length of an image of the negative film is read at a time, whereas in the main scan, the frame image is read in units of one frame. In addition, the scanning speed in the sub-scanning direction is considerably slow, and it takes time from the completion of the pre-judgement operation to the start of printing, and this time is a hindrance to the reduction of the overall processing speed.
[0005]
In order to solve such a problem, for example, in Japanese Patent Application Laid-Open No. H11-215305, the main scan is performed before the pre-judgment operation for all frame images is completed, that is, when the pre-judgment operation for a predetermined number of frame images is completed. Is configured to start. However, even in this improvement, if it takes time to prejudge a predetermined number of frame images, the start of the main scan is also delayed by that much, which causes a reduction in the overall processing speed.
[0006]
In print services such as attraction venues, print processing is required as soon as possible, so even a slight reduction in processing speed cannot be ignored. In view of such circumstances, an object of the present invention is to provide a photographic film image processing apparatus having high processing efficiency, which eliminates wasted time in film image processing from pre-scanning to pre-judgement work, main scanning, and print creation. It is to be.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, a photographic film image processing apparatus for processing an image of each frame recorded on a photographic film according to the present invention includes a line sensor that scans in a main scanning direction along a transverse direction of the photographic film; A sub-scanning movement mechanism for relatively moving the image sensor and the line sensor in a sub-scanning direction along the longitudinal direction of the photographic film, and frame image data of frames included in the photographic film by the first relative movement by the sub-scanning movement mechanism And a main scan mode for acquiring image data of frames included in the photographic film at a higher resolution than the prescan mode by the second relative movement by the sub-scanning movement mechanism. Unit and a monitor image displaying a frame image based on the image data acquired in the pre-scan mode. A pre-judge control unit for controlling a pre-judgment step of inputting attribute data to the displayed frame image, and print data obtained by image-processing the main scan image data corresponding to the frame image for which the attribute data has been input. An image data processing unit for converting the image data into a frame image. The reading control unit reads a frame image of the photographic film in the main scan mode in parallel with a pre-judge process by the pre-judge control unit.
[0008]
In this configuration, after the pre-scan is completed, the main scan is performed together with the pre-judge process. In other words, in some cases, a full scan of the print target frame image is performed prior to input of attribute data such as input of a correction command to the print target frame image and input of the number of prints in the pre-judge process, so that a time-consuming main scan can be totally processed. Time-consuming situations are avoided as much as possible. In other words, in the present invention, if the pre-judge work is completed and the pre-scan is completed anyway, even if the pre-judge work is not completed, even if the pre-judge work has not been completed, Then, the main scan is performed.
[0009]
2. Description of the Related Art When a frame image of a photographic film is read by a scanner and digital printing is performed using the obtained image data, a method of changing the reading magnification of the scanner according to the print size has conventionally been adopted. That is, when the print size is small, the resolution required for printing may be small, so that a frame image is formed on a part of the linear sensor, the sub-scanning speed is correspondingly increased, and conversely, the print size is large. In this case, since the resolution required for printing is large, a frame image is formed on most of the linear sensor, and the sub-scanning speed is reduced correspondingly. The adjustment of the image size of the frame image on the linear sensor is performed by a plurality of optical lens units or a zoom lens unit that can be switched by a turret. Since a plurality of frame images included in one photographic film (in other words, one order) are not always printed in the same print size, in the related art, a main scan is performed after a print size is input.
[0010]
On the other hand, in the present invention, since the main scan is performed in parallel with the pre-judge process, the reading magnification is not adjusted according to the print size. Instead, in a preferred embodiment of the present invention, an optical lens unit capable of forming a film image at a selectable magnification with respect to a line sensor is provided, and in the main scan mode, the optical lens unit is a pre-press. The magnification is set to be commonly used for a plurality of print sizes that can be input as one of the attribute data during the judge work. In other words, when a print order is received from a photographic film, the types of print sizes included in the order (that is, in one order), for example, L size and 2L size, are known, and these types of prints are known. An optical lens unit, usually a zoom lens unit, is set to a magnification that can cover the size. Since the resolution for the 2L size is naturally larger than the resolution for the L size, the conversion for lowering the resolution to an appropriate level may be performed when printing the L size.
Even if the main scan is performed independently of the pre-judge process, the size of the image data acquired by the main scan can be several to several tens of megabytes (sometimes more than one hundred megabytes). Providing a memory for storing the image data of one frame image should be avoided in view of cost. For this reason, in a preferred embodiment of the present invention, a main scan storage memory for temporarily storing the frame image data acquired by the main scan until the image data is converted into print data is provided. The image data is continuously obtained until the main scan storage memory is full.
[0011]
In a photographic film image processing apparatus according to the present invention configured to be able to perform a main scan following a prescan, the prescanned photographic film must be prepared for the main scan as quickly as possible. In consideration of this point, in the configuration in which the pre-scanned photographic film is rewound and then the main scan is performed, the rewound time is a waste time. For this reason, in a preferred embodiment of the present invention, the sub-scanning moving mechanism of the film scanner conveys the photographic film along one conveying line, and the first relative movement for the pre-scan is performed on the conveying line. The second relative movement for the main scan is performed by the backward transport of the photographic film on the transport line. This saves the rewind time before the main scan.
[0012]
Other features and advantages according to the present invention will become apparent from the following description of embodiments with reference to the drawings.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is an external view of an example of a photographic film image processing apparatus according to the present invention. In this example, the photographic film image processing apparatus performs exposure processing and development on a silver halide photographic paper P (hereinafter, referred to as photographic paper P). A print station 1B as a photographic printer for performing processing and an operation for generating and transferring print data used in the print station 1B based on frame image data read from a photographic film (hereinafter simply referred to as a film) F Station 1A. This photographic film image processing apparatus is also referred to as a digital minilab. As can be clearly understood from FIG. 2, the print station 1B transfers the roll-shaped photographic paper P stored in two photographic paper magazines 11 to the inside of the print station 1B. And the paper P cut in this manner is exposed to light by the exposure processing section 12, and the photographic paper P after the exposure is subjected to a developing process having a plurality of developing tanks. It is sent to the unit 13 for development. The photographic papers, that is, the photographic prints P sent to the sorter 15 from the horizontal conveyor 14 at the upper portion of the apparatus after the drying are accumulated in a state where they are sorted on a plurality of trays 15a of the sorter 15 in order units.
[0014]
The exposure processing unit 12 performs exposure of light rays of three primary colors of R (red), G (green), and B (blue) while sending photographic paper P based on print data sent from the operation station 1A. (Not shown) so that the photographic paper P is conveyed in the sub-scanning direction during exposure, and is exposed in a line along the main scanning direction in synchronization with the conveyance speed. Note that, as the exposure head, a fluorescent beam method, a laser beam method, a liquid crystal shutter method, a DMD method, or a FOCRT method can be adopted according to the exposure specification. The developing section 13 has a transport system having a number of pressure rollers (not shown) so as to continuously send the exposed photographic paper P to a plurality of developing tanks.
[0015]
The operation station 1A includes a film scanner 2 for acquiring frame image (photographed image) data from a photographic film F at an upper position of a desk-shaped console provided with an operation table 16, and a CRT display (hereinafter simply referred to as a monitor) for displaying various information. 17). Further, on the operation table 16, a keyboard 18a and a mouse 18b functioning as an operation input unit 18 of the photographic film image processing apparatus are arranged. A general-purpose computer (hereinafter simply referred to as a personal computer) serving as a controller for processing image data read from the photographic film F through the film scanner 2, generating print data, and controlling the print station 1B is provided below the operation table 16. 4) is provided.
[0016]
As shown schematically in FIGS. 2 and 3, the film scanner 2 includes a light source 20 located above a driving roller type film transport line configured as a sub-scanning moving mechanism 30, and a film transport line A zoom lens unit 22 as an optical lens unit positioned below a slit 21 extending in a direction orthogonal to the lower side, and a CCD that photoelectrically converts transmitted light of a film F formed by the zoom lens unit 22. The linear type sensor unit 23 is provided. The sensor unit 23 is connected to the controller 4, and the digital image data photoelectrically converted by the sensor unit 23 is taken into the controller 4.
[0017]
When reading the frame image from the developed film F, while the film F set at the end of the film transport line of the sub-scanning moving mechanism 30 is transported, the sensor unit 23 synchronizes with the transport and transmits the film transmitted light. Is separated into R (red), G (green), and B (blue) one line at a time along the main scanning direction, and then photoelectrically converted, and each of R (red), G (green), and B (blue) is separated. Frame image data composed of luminance data is transferred to the controller 4. The film scanner 2 reads one film continuously at a low resolution in the pre-scan mode. The prescan image data is cut out for each frame image based on the density difference to become prejudgment image data. The main scan performed after the frame position information obtained at the time of the cutout is used as the frame position data. Sometimes used. Depending on the subject, there is almost no density difference between the photographing screen area and the non-photographing screen area, and the frame image edge may not be detected mechanically.In this case, the operator may input frame position data by visual judgment. It is possible.
[0018]
In the high-resolution main scan mode, scanning by the sensor unit 23 is started at the front edge of each frame image based on the above-described frame position data, and scanning is stopped at the rear edge. The image data is sequentially taken into the personal computer 4. Even in the same main scan mode, the resolution of the acquired image data differs depending on the target print size, so that the imaging magnification of the frame image on the sensor unit 23 of the zoom lens unit and the conveyance of the sub-scanning movement mechanism 30 It is necessary to adjust the (scanning) speed.
[0019]
In order to obtain relatively low-resolution scan image data (main scan image data) suitable for a small print size, the magnification of the zoom lens unit 22 is set low (see FIG. 3A) and the sub-scanning movement mechanism In order to set the transport speed of the zoom lens unit 30 at a high speed and obtain relatively high-resolution scan image data (main scan image data) suitable for a large print size, the magnification of the zoom lens unit 22 is set to a relatively high value ( The transport speed of the sub-scanning movement mechanism 30 is set to be slow. For example, when outputting an L or 2L size print, a resolution of about 16 BASE (2048 × 3072; 18.9 Mbytes) is required, the magnification of the zoom lens unit 22 is approximately equal, and the transport speed is approximately 20 mm / sec. In the case of outputting with a print size of about four cuts, a resolution of about 64 BASE (4096 x 6144; 75.5 megabytes) is required, the magnification of the zoom lens unit 22 is about twice, and the transport speed is about 5 mm / sec. .
[0020]
The personal computer 4 used as the controller 4 of this photographic film image processing apparatus has a CPU as a core member, and a functional unit for performing various processes on the transferred photographic image data is hardware or software or the same. As shown in FIG. 4, as a functional unit particularly related to the present invention, the zoom lens unit 22 and the sub-scanning moving mechanism 30 are controlled to perform the pre-scan mode and the main scan. A film scanner controller 40 serving as a reading controller for driving the film scanner 2 in the mode, a buffer memory 45 for temporarily storing image data transferred from the film scanner 2, and each frame included in the film F to be processed. Attach attribute data such as image processing commands and number of prints to the image as needed A rejudge management unit 41, an operation input processing unit 42 for allocating operation commands such as an image processing command corresponding to an operation input signal from the operation input unit 18, and a video control unit for displaying an image of a shooting frame to be corrected on the monitor 17 during prejudgment. 43, an image processing unit 50 that performs various image processing on the high-resolution image data captured in the main scan mode, and prints the final high-resolution image data processed by the image processing unit 50 to the print specifications of the print station 1B. And a print data generation unit 44 that converts the print data into print data in accordance with the print data.
[0021]
The pre-judge management unit 41 generates frame position data indicating a frame position from low-resolution image data (pre-scan image data) captured in the pre-scan mode in consideration of a density difference, and uses the frame position data. A pre-judge image processing unit 41a for generating pre-judge image data in frame image units from pre-scan image data covering the entire film, using simulated image data corresponding to a print output image expected from the pre-judge image data Simulated image generating unit 41b which generates the color output characteristics of the monitor 17 and the exposure processing unit 12 while referring to the device characteristic table stored therein, and sets each frame image through the operation input processing unit 42 at the time of pre-judgment. Manages image processing commands or image processing command sequences Image processing command string management unit 41c is provided that.
[0022]
The image processing unit 50 includes a first image processing unit 51 that performs pre-processing such as image rotation, γ correction, and resolution conversion on the high-resolution image data captured in the main scan mode, and a color tone correction and filtering (for blurring and A second image processing unit 52 that performs various photo retouching processes such as sharpness and trimming is included. The resolution conversion is used to set the image data of the frame image that has been main-scanned at a resolution different from the optimum resolution for a predetermined print size to the optimum resolution for print output. This is because, in the photographic film image processing apparatus of this embodiment, all frame images included in one film F are set at a common magnification setting even if print outputs of different print sizes are included. This is for performing the main scan at the resolution.
[0023]
FIGS. 5 and 6 show a processing procedure in the photographic film image processing apparatus when a frame image of the developed film F is printed, and FIG. 7 shows a flow of image data at that time.
First, necessary information such as the number of prints and the print size is input from the contents of the print order received from the customer (# 10). A control channel defining various control parameters of the photographic film image processing apparatus is set based on the input print order information (# 20). The control parameters included in the control channel include the maker and type of photographic paper to be used, the print size of a photographic print to be created, and the like. The film F to be processed is fed into the sub-scanning movement mechanism 30 of the film scanner 2 to perform pre-scan (# 30). In the pre-scan, all the frame images included in the film F are continuously transferred at a low resolution (for example, 256 × 384 pixels) while the film F is transferred in one direction of the transfer line formed in the sub-scanning moving mechanism 30. It is read (# 40). When the prescan is completed, the main scan is performed while the film F is transported in the reverse direction (# 50). The main scan is intermittently read at a high resolution (for example, 2048 × 3072 pixels) in frame image units (# 50). Since the capacity of image data per one frame image acquired in the main scan becomes considerably large, it is necessary to check the freeness of the buffer memory 45 while performing the check.
[0024]
The procedure of the main scan will be described in detail with reference to FIG.
First, it is checked whether or not one order, that is, a plurality of print sizes of the photographic prints P to be printed from one film F is included (# 51). The zoom lens unit 22 of the film scanner 2 is set to a certain magnification (# 52a), and if there are a plurality of types, the zoom lens unit 22 of the film scanner 2 is set to a magnification having a common resolution that can be adapted to all of the print sizes. (# 52b). Next, the first frame image is captured while transporting the film F in the direction opposite to the direction of the prescan (# 53). When resolution conversion is necessary for the captured frame image data, the first image processing unit 51 performs the resolution conversion together with other preprocessing (# 54, # 55). When the frame image data is preprocessed, a request is made to the second image processing unit 52 for image processing based on an image processing command set at the time of the pre-judge work described later (# 56). Next, it is checked whether or not there is still a frame image to be main-scanned (# 57). If there is no main image, the main scan is completed, but if there is, there is room to store main-scan frame image data in the buffer memory 45. It is checked whether or not there is sufficient space in the buffer memory 45 (# 58), and a main scan for the next frame image is performed (jump to # 53).
[0025]
As is apparent from FIG. 5, what is important for the present invention is that the above-described main scanning step is started substantially simultaneously with the start of the preparation of the pre-judge image data used for the pre-judge operation.
[0026]
The pre-judge image data is obtained by cutting out an area corresponding to each frame image from the pre-scan image data based on a density difference from a peripheral region and a known frame image size. When the pre-judge image data is obtained, the pre-judge image is displayed on the monitor 17 and a well-known pre-judge operation is performed, and a correction processing command is set as necessary (# 60). . The image processing based on the correction processing command set in the pre-judge work as part of the print processing is performed by the image processing unit 50 on the corresponding high-resolution frame image data obtained in the main scan, and the image processing is completed. The frame image data is converted into print data and sent to the print station 1B, where a photographic print P is created (# 70).
[0027]
Again, what is important for the processing procedure in this photographic film image processing apparatus is that the film scanner controller 40 performs the pre-judge process including the pre-judge image generation by the pre-judge controller and the pre-judge operation by the operator. This is to read the frame image of the film F in the scan mode, which can be clearly understood from the time chart shown in FIG. In this time chart, circled numbers indicate frame image numbers, and the main scan of the first two frame images is continuously performed together with the pre-judge process. This is because the buffer memory 45 has a capacity to store two main scan frame image data.
[0028]
Next, how a frame image or frame image data is processed by each component of the photographic film image processing apparatus will be described with reference to FIG.
When the film F is set on the film scanner 2, one film is continuously scanned at a low resolution over its length (pre-scan), and sent out to the buffer memory 45 (# 101). The low-resolution image data temporarily stored in the buffer memory 45 is subjected to necessary pre-processing such as gamma conversion and image rotation by the first image processing unit 51 of the image processing unit 50, and is transferred to the pre-judge management unit 41 ( # 102). The pre-judge image processing unit 41a determines a frame position from the low-resolution image data transferred to the main memory, cuts out image data corresponding to each photographed frame, and sets it as pre-judge image data (# 103).
[0029]
Further, the pre-judge image data is converted into simulated image data by performing a predetermined process by a simulated image generation unit 41b. The print color characteristics determined by the exposure head and the type of photographic paper used in the processing unit 12, the monitor color characteristics of the monitor 17 used for displaying the simulated image, and the like are read from the device color characteristic table, and the simulation is performed. The image is referred to in the image generation process (# 104).
[0030]
When the simulated image data is sent to the video control unit 43 (# 105), the simulated image is displayed on the monitor 17 (# 106). In the pre-judgment operation, the operator operates a predetermined operation key or a mouse 18b on the keyboard 18a as the operation input unit 18 as needed while watching the photographing frame to be processed as the simulated image (# 107). An image processing command is generated by the operation of the operation input processing unit 42 and sent to the pre-judge management unit 41. The pre-judge management unit 41 corrects the simulated image data by giving the received image processing command to the simulated image generation unit 41b, whereby the simulated image displayed on the monitor 17 is adjusted as requested by the operator. (# 108). When the pre-judgment operation for the processing target shooting frame displayed on the monitor 17 is completed in this way, the image processing command applied to this shooting frame is temporarily held by the image processing command sequence management unit 41c. (# 109). Note that the image processing command sequence including the image processing commands includes image processing commands related to image correction that are automatically set in addition to the image processing commands input by the operator's operation. At this point, the photo print process of the photographed frame for which the pre-judgment has been completed starts.
[0031]
The pre-judgment operation is performed in various forms. Here, a typical example will be briefly described with reference to FIG.
On this monitor screen, simulated images 70 for six photographed frames are displayed, and a numeral indicating a frame number for specifying a corresponding photographed frame is displayed in a frame area 71 on the upper side of each simulated image 70, In the correction information frame 72 on the side, a character "Y" corresponding to yellow, a character "M" corresponding to magenta, a character "C" corresponding to cyan, and a character "D" to indicate density correction information Is displayed, and a numerical value indicating the number of prints is displayed in the lower print number frame 73. When a plurality of simulated images 70 are displayed in this manner, the simulated images are in a selected state by giving a noticeable hue to the selection frame 74 surrounding one of the simulated images 70. It clearly states that: In the lower area of the monitor screen, there are arranged a frame 75 indicating the order number and the type of image media, and buttons 76 for ending the pre-judgement of the currently displayed shot frame and displaying the next shot frame to be prejudged.
[0032]
When the simulated image 70 is displayed on the monitor 17 as described above, for example, when the yellow key is operated as the operation key set on the keyboard 18a, the correction corresponding to the selected simulated image 70 is performed. The display of highlighting the character "Y" in the information frame 72, the display of inverting the character, and the display of blinking are performed so that the operator recognizes that the yellow component is selected as the correction target, and in this state, the plus is added. When the key is pressed, an image processing command for gradually increasing the yellow component by the number of times the key is pressed is generated by the image processing command sequence management unit 41c and given to the simulated image generation unit 41b. When image processing is performed and the minus key is pressed in the same way, the yellow component is reduced stepwise by the number of times the button is pressed. It is processed made to the process to return to the state before correction when pressed neutral key is performed. Filtering processing such as blurring and sharpness is similarly performed by operating the set operation key.
[0033]
In the case of the trimming process, one simulated image 70 to be processed is displayed on a monitor screen (not shown) in order to perform accurate trimming, and the trimming cursor is operated by the mouse 18b. An image area to be printed in a shooting frame is set. The trimming data is also managed and stored as one of the image processing commands by the image processing command sequence management unit 41c.
[0034]
By the main scan performed in parallel with the pre-judge process, high-resolution image data in units of frame images is sequentially captured in the buffer memory 45 (# 110), and necessary gamma conversion, image rotation, and resolution are performed by the first image processing unit 51. Preprocessing such as conversion is performed (# 111). When the input of attribute data such as the number of prints and color correction for the frame image corresponding to the high-resolution image data temporarily stored in the buffer memory 45 has been completed, the second image processing unit 52 sets the image processing command sequence management unit 41c. Receives the corresponding image processing command (column) from the printer (# 112), performs image processing based on the image processing command, and provides the processed high-resolution image data to the print data generation unit 44 (# 113).
[0035]
The print data generating unit 44 converts the received image-processed high-resolution image data into print data of a specification used in the print station 1B, and transfers the print data to the exposure processing unit 12 of the print station 1B to create a photographic print. Is performed (# 114).
[0036]
In the above-described embodiment, the frame image data of the frame included in the film F is obtained by the relative movement in the first direction by the sub-scanning movement mechanism 30 at the time of the pre-scan, ie, the forward movement, and at the time of the main scan. Although the image data of the frame included in the photographic film was obtained by the second relative movement by the mechanism, that is, the backward movement, the film was rewound at the time of the main scan, and was again moved in the first relative movement, that is, the forward movement. A configuration for acquiring data may be adopted.
Further, a silver halide printer for producing a photographic print by exposing and developing photographic paper P is taken as the print station 1B, but an ink jet printer, a thermal transfer printer, or a sublimation printer may be employed.
