Description

  The present invention relates to a printed material production system and a printed material production method for producing a printed material on which a face image is printed.

  2. Description of the Related Art Conventionally, there is known a box-type photography apparatus for taking an identification photograph or the like to be attached to a license, passport, resume, or the like. The photographic device reduces (resizes) the photographed face image by changing the magnification, and prints and outputs photographs of various sizes according to the application. The photographic device is provided with a monitor for displaying a face image, and the face image to be printed can be confirmed in advance.

  Recently, as a value-added function especially for women, a photographic apparatus having a “skin-beautifying process” function that reduces a fine unevenness of the face (skin) and a rough feeling and processes it into a smooth texture is known.

  In skin-beautifying treatment, for example, while maintaining the sharpness of the contours of the face and the contours of hair, eyes, nose, mouth, etc., it is possible to remove and reduce spots and wrinkles on the skin of the face, and to reduce unevenness. Then, a smoothing process that makes it look smooth is performed (see, for example, Patent Documents 1 and 2).

  Conventionally, a skin beautification process is performed on a face image with a large data size captured by a photographing device, and then a resize process is performed for printing or monitor display. However, there is a problem that it takes time to perform skin beautification on a face image having a large image data size.

  Further, when the photograph size to be printed is reduced, the expressive power (descriptive property) of the fine parts is lowered, and this brings about the same effect as the skin beautification process. As in the prior art, when the image after the skin beautification process is resized, the skin beautifying effect suitable for the photo size cannot be obtained. Moreover, the display resolution of the monitor screen is low, and it is difficult to visually confirm the skin beautifying effect.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows a schematic configuration of a print production system according to the present embodiment. The printed matter production system includes a photographing device 2 for photographing the face of the subject P and generating face image data, an arithmetic control device 1 for performing image processing on the face image data, and a printed matter (photograph). A printer 5 for printing and a strobe 6 for irradiating the subject P with light when the photographing apparatus 2 photographs the face of the subject P are provided. The photographing apparatus 2 is a digital camera, for example, and includes a lens, a shutter, a CMOS sensor, an A / D converter, and the like. When the photographing device 2 photographs the face of the person P, the CMOS sensor receives photographing light converged by the lens through a shutter and photoelectrically converts an optical image formed on the light receiving surface. And output as an image signal. The A / D converter A / D converts the image signal output from the CMOS sensor to generate face image data. The photographing device 2 outputs the face image data to the arithmetic control device 1.

  The print production system includes a touch panel (instruction receiving unit and display unit) 3 that receives various instructions from the photographed person P and displays a preview image.

  The touch panel 3 displays an operation button, and when the operation button is pressed, receives an operation instruction corresponding to the operation button. For example, the touch panel 3 receives from the user (photographer P) an instruction for an image size (photo size) that the printer 5 prints on a printed material. The photo size corresponds to, for example, a driver's license, passport, visa, and the like. Also, the photo size may be customized. The touch panel 3 can accept a print start instruction for the printer 5 from the user.

  Further, the print production system is provided with a billing unit (not shown) for accepting money paid by the photographed person P as the price of the print, or paying out change.

  The arithmetic control device 1 is connected to the photographing device 2, the touch panel 3, the printer 5, the strobe 6, and the accounting unit, and controls each unit and transfers data.

  FIG. 2 shows a hardware configuration of the arithmetic control device 1. The arithmetic control device 1 includes a CPU (central processing unit) 11, a main memory 12, a disk device 13, and an input / output unit 14. Each part of the arithmetic and control unit 1 is connected via a bus 15.

  The disk device 13 stores an image processing program 16 executed by the CPU 11. Further, the disk device 13 stores a table 17 that defines the processing content corresponding to each of the skin beautifying processes in a plurality of processing modes. The skin beautification process will be described later. The disk device 13 is, for example, a hard disk drive. The image processing program 16 may be stored not in the disk device 13 but in a ROM or a magnetic tape (both not shown).

  The CPU 11 loads the image processing program 16 in the disk device 13 into the main memory 12 and executes the image processing program 16. At this time, the table 17 in the disk device 13 may be loaded into the main memory 12.

  As the image processing program 16 is executed, an area for storing the face image data, the preview image data, and the print image data is secured on the main memory 12. The preview image data is image data displayed as a preview image on the touch panel 3, and the print image data is image data printed by the printer 5.

  FIG. 3 shows a functional block diagram realized by the CPU 11 executing the image processing program 16. By executing the image processing program 16, a resizing unit 21, a selecting unit 22, a first image processing unit 23, and a second image processing unit 24 are realized.

  The resizing unit 21 reduces the face image data generated by the photographing device 2 to a size corresponding to the size of a photograph to be printed by the printer 5, and generates image data for printing. For example, the image can be reduced by evenly thinning out vertical and horizontal pixels. The photo size printed by the printer 5 is instructed via the touch panel 3.

  Further, the resizing unit 21 reduces the face image data received from the photographing apparatus 2 to a size corresponding to the preview display on the touch panel 3, and generates preview image data. The display size on the touch panel 3 may be determined in advance, or may be instructed via the touch panel 3.

  In general, since the size of the face image data generated by the photographing apparatus 2 is larger than the print size and the preview size, the resizing unit 21 often performs a reduction process, but may perform an enlargement process. For example, an image can be enlarged by interpolating pixels.

  The first image processing unit 23 performs image processing on the print image data. The image processing performed here is a so-called beautiful skin treatment that reduces the fine unevenness of the face (skin) and the sensation of smoothness and processes unwanted parts that impair the appearance of wrinkles and spots. It is. The first image processing unit 23 extracts a skin area of the face image, and performs a skin beautification process on the skin area.

  An example of skin area extraction processing will be described. First, a region below both eyes of the face image, more strictly, a region that straddles the contours of both sides of the nose and does not cover hair, eyes, or nostrils is defined as a reference region. Then, an average pixel value of each pixel included in the reference area is obtained as an average pixel value, and a pixel value within a predetermined range of a color difference with respect to the average pixel value is determined from each pixel constituting the entire print image. Extract the pixels it has. A region composed of the set of extracted pixels is a skin region.

  The skin beautification process is a known technique in the technical field of image processing. Here, an example of skin beautifying process that can be performed by the first image processing unit 23 will be described. For example, by applying filter processing such as a filter exhibiting a predetermined soft focus effect or a low-pass filter to an image, fine unevenness, a rough feeling, wrinkles, spots, and the like can be reduced. In addition, dullness and the like can be reduced by increasing the saturation of the skin region.

  By changing the filter used for the skin beautification and the correction level (raising range) of the saturation, the strength of the skin beautification can be changed. For example, by increasing the filter strength or increasing the saturation correction level, it is possible to perform a strong skin-beautifying process. On the other hand, by reducing the filter strength or reducing the saturation correction level, it is possible to perform skin beautification processing with low strength.

  Moreover, the intensity | strength of a skin beautification process can be adjusted by using the skin beautification processing function of well-known image processing software. For example, “Daisy Collage” in the Ichikawa Soft Laboratory “makeup” to correct skin spots, freckles and dullness, “whitening” to correct the whole skin white, “beautiful skin” to blur the unevenness of the skin, and the whole skin The effect intensity can be adjusted by adjusting parameters such as “soft white”, which applies a “whitening” effect to the image and corrects it brightly and softly. In addition, the skin color can be made whiter, tanned wheat color, redness can be emphasized, and redness can be suppressed. Furthermore, it is possible to adjust the texture of the skin by applying an effect so as to blur the image.

  In this embodiment, a plurality of processing modes corresponding to the strength of the skin beautifying process are provided. The disk device 13 stores a table 17 in which combinations of saturation correction levels and use filters associated with each processing mode are defined as shown in FIG. The disk device 13 also stores each filter.

  The first image processing unit 23 performs the skin beautification process in the processing mode selected by the selection unit 22 described later. The first image processing unit 23 refers to the table 17 stored in the disk device 13, determines a saturation correction level and a use filter, and performs skin beautification processing on the print image data. Based on an instruction from the user (photographer P), image data for printing that has undergone skin beautification processing by the first image processing unit 23 or image data for printing that has not undergone skin beautification is input to the input / output unit 14. Via the printer 5.

  The selection unit 22 selects a skin softening processing mode to be executed by the first image processing unit 23 based on a photo size instruction instructed via the touch panel 3. For example, the selection unit 22 selects a processing mode in which the strength of the skin beautifying process is weaker as the photo size is smaller. When the photograph size to be printed is reduced, the expressive power (descriptive property) of fine parts is reduced, and this brings about an effect equivalent to performing skin beautification. Therefore, when the photo size is small, the strength of the skin beautifying process performed by the first image processing unit 23 is weakened.

  The second image processing unit 24 performs image processing on the preview image data. The image processing performed here is the same as the skin beautification process described above. The second image processing unit 24 extracts a skin area of the face image, and performs a skin beautification process on the skin area.

  In addition, the second image processing unit 24 executes a skin beautifying process having a higher strength (than the first image processing unit 23). The preview image data is data displayed on the touch panel 3, but the display resolution of the screen of the touch panel 3 is low. Therefore, a strong skin treatment is performed so that the skin effect can be visually confirmed. For example, the second image processing unit 24 refers to the table 17 stored in the disk device 13, and uses the saturation correction level and filter corresponding to the strong processing mode to perform skin beautification processing on the preview image data. Apply. The preview image data that has undergone skin beautification processing by the second image processing unit 24 is output to the touch panel 3 via the input / output unit 14. In addition, preview image data that has not undergone skin beautification processing is also output to the touch panel 3 via the input / output unit 14.

  The touch panel 3 receives preview image data that has undergone skin beautification processing and preview image data that has not undergone skin beautification processing from the arithmetic and control unit 1, performs color conversion and sharpness processing, and displays them on the screen.

  As shown in FIG. 5, the touch panel 3 displays an image that has undergone skin beautification and an image that has not been subjected to side-by-side display. An image that has not undergone skin beautification is displayed on the touch panel 3 having a low display resolving power, thereby obtaining an effect equivalent to that of performing skin beautification. However, since the strong skin beautifying process is performed by the second image processing unit 24, the user can recognize the difference in the presence or absence of the skin beautifying process even on the screen of the touch panel 3.

  Further, as shown in FIG. 5, the touch panel 3 displays print execution buttons 31 and 32 below each preview image. When the user presses the print execution button 31 corresponding to the preview image not subjected to the skin beautification process, the print image data not subjected to the skin beautifying process is output from the arithmetic control device 1 to the printer 5. On the other hand, when the user presses the print execution button 32 corresponding to the preview image subjected to the skin beautification process, the print image data subjected to the skin beautifying process is output from the arithmetic control device 1 to the printer 5.

  The display format of the preview image on the touch panel 3 is not limited to that shown in FIG. For example, as shown in FIG. 6, a skin beautification image preview button 41 and a normal image preview button 42 are displayed. When the skin beautification image preview button 41 is pressed, a preview image after the skin beautification process is displayed, and the normal image preview button 42 is displayed. When is pressed, a preview image that has not undergone skin beautification may be displayed.

  In addition, as shown in FIG. 7, a switching button 51 is displayed, and each time the switching button 51 is pressed, a preview image that has not undergone skin beautification processing and a preview image that has undergone skin beautification are switched and displayed. Also good.

  The printer 5 performs color conversion and sharpness processing on the print image data received from the arithmetic and control unit 1. Then, the printer 5 prints the photographed image of the person P to be printed on paper. The printing method of the printer 5 is not particularly limited, and an ink jet method, a sublimation type thermal transfer method, a melt type thermal transfer method, or the like can be used.

  Next, a print production method using such a print production system will be described with reference to the flowchart shown in FIG.

  (Step S <b> 101) The touch panel 3 receives an instruction for a photo size to be printed.

  (Step S <b> 102) The photographing apparatus 2 photographs the person P (user) and generates face image data. When the photographing device 2 performs photographing, the strobe 6 irradiates the person P with light.

Specifically, the face image data is resized based on the photo size instructed in step S101, and print image data is generated. Further, the face image data is resized in accordance with the preview display on the touch panel 3 to generate preview image data.

  (Step S104) The first image processing unit 23 performs a skin beautification process on the print image data. The processing mode (intensity) of the skin beautification process in the first image processing unit 23 is selected by the selection unit 22 based on the photo size instructed in step S101. The selection unit 22 selects a processing mode in which the strength of the skin beautifying process is weaker as the photo size is smaller. The first image processing unit 23 refers to a table 17 as shown in FIG. 4 stored in the disk device 13 and executes skin beautification processing.

  Further, the second image processing unit 24 performs skin beautification processing on the preview image data. The second image processing unit 24 executes a strong skin beautifying process so that the skin beautifying effect can be visually confirmed on the screen of the touch panel 3 having a low display resolution. For example, a skin beautifying process having a strength higher than that of the first image processing unit 23 is executed.

  (Step S105) The touch panel 3 displays the preview image data that has undergone skin beautification and the preview image data that has not undergone skin beautification arranged or switched.

  (Step S <b> 106) The user determines whether or not to perform a skin beautification process on the face image from the preview image displayed on the touch panel 3. When the skin beautification process is performed, the process proceeds to step S107, and when the skin beautification process is not performed, the process proceeds to step S108.

  (Step S107) The user presses the print execution button 32 corresponding to the preview image displayed on the touch panel 3 and subjected to the skin beautification process. As a result, the arithmetic and control unit 1 outputs to the printer 5 the image data for printing that has undergone skin beautification processing.

  (Step S108) The user presses the print execution button 31 corresponding to the preview image displayed on the touch panel 3 and not subjected to the skin beautification process. As a result, the arithmetic and control unit 1 outputs to the printer 5 image data for printing that has not undergone skin beautification processing.
