The printed material production device includes a photographing device 2 that photographs a subject P and generates a photographed image, an arithmetic control device 1 that performs image processing on the photographed image, and a printer 5 that prints a printed matter (photograph). And a strobe 6 that irradiates the subject P with light when the photographing device 2 photographs the subject P. This print production apparatus cuts out a person portion from a photographed image, prints a composite image obtained by synthesizing a person image and a background image, and outputs the print image. The wallpaper on the back side of the subject P in the print production apparatus has a color suitable for chroma key composition, for example, blue or yellow-green.

  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 imaging device 2 captures the subject P, the CMOS sensor receives the imaging light converged by the lens through the shutter, and photoelectrically converts the optical image formed on the light receiving surface, Output as an image signal. Then, the A / D converter performs A / D conversion on the image signal output from the CMOS sensor, and generates captured image data. The photographing device 2 outputs the photographed image data to the arithmetic and control device 1.

  The print production apparatus includes a touch panel (an instruction receiving unit and a display unit) 3 that receives various instructions from the subject 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 an instruction on the use of the printed material from the user (photographer P). The use of the printed matter corresponds to the image size (photo size) that the printer 5 prints on the printed matter, and is, for example, a driver's license, passport, resume, and the like. The touch panel 3 can display at least one background image candidate and can accept a background image selection instruction from the user. In addition, the touch panel 3 can accept instructions such as color, brightness, pattern, and gradation for the user to customize the background image. The touch panel 3 can accept a print start instruction for the printer 5 from the user. In addition, the touch panel 3 can enlarge and display a portion touched by the user while displaying a preview image to be described later.

  Further, the print production apparatus 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 and a background image database 17 to be combined with a person image. The database 17 stores a plurality of background image data having different colors and patterns.

  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.

  As the image processing program 16 is executed, an area for storing captured image data, person image data, background image data, and composite image data is secured on the main memory 12.

  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 selection unit 21, an image processing unit 22, and a custom background creation unit 23 are realized.

  The selection unit 21 selects and extracts background image data from the disk device 13 and outputs the background image data to the touch panel 3 as background image candidate data. When the selection unit 21 receives a background image selection instruction from the user via the touch panel 3, the selection unit 21 passes the background image data selected by the user to the image processing unit 22.

  The image processing unit 22 synthesizes the person image in the photographed image generated by the photographing device 2 and the background image received from the selection unit 21 using a process based on chroma key composition, and creates composite image data. Specifically, the image processing unit 22 determines the color difference between the person in the captured image and the background color (wallpaper color), and cuts out the person image from the captured image. The color difference determined here is a hue difference, a saturation difference, or a combination of a hue difference and a saturation difference. Then, the image processing unit 22 performs image composition by superimposing the background image received from the selection unit 21 and the cut-out human image.

  Further, when receiving a custom background image from a custom background creation unit 23 described later, the image processing unit 22 synthesizes the person image and the custom background image to create composite image data.

  In addition, the image processing unit 22 extracts a part having the same color as the background color (wallpaper color) in the photographed image from the person image cut out from the photographed image, and sets the extracted part color to the complementary color of the background color or white. The image is converted and the person image after color conversion (background color converted person image) and the background image or custom background image are combined to create background color converted combined image data.

  The image processing unit 22 reduces the captured image data generated by the imaging device 2, the created composite image data, and the background color conversion composite image data to a size corresponding to the preview display on the touch panel 3, and generates preview image data. To do. In addition, the image processing unit 22 reduces the generated composite image data to a size corresponding to the size of a photograph to be printed by the printer 5 and generates print image data. For example, the image can be reduced by evenly thinning out vertical and horizontal pixels. The photo size printed by the printer 5 corresponds to the use instructed via the touch panel 3.

  The custom background creation unit 23 creates a custom background image that suits the user's preference based on the color, pattern, or the like designated by the user via the touch panel 3. The custom background creation unit 23 passes the created custom background image to the image processing unit 22.

  When a print start instruction for the printer 5 is received from the user via the touch panel 3, image data for printing is output from the arithmetic control device 1 to the printer 5.

  The printer 5 shown in FIG. 1 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, the printed matter manufacturing method according to the present embodiment will be described with reference to the flowchart shown in FIG.

  (Step S <b> 101) The touch panel 3 receives an instruction for the purpose of a photograph to be printed.

  (Step S102) The person P to be photographed performs a deposit process.

  (Step S103) The imaging device 2 captures the subject P and generates captured image data. When the photographing device 2 performs photographing, the strobe 6 irradiates the person P with light.

  (Step S104) The image processing unit 22 resizes the captured image data generated in step S103 to generate preview image data. Then, the touch panel 3 displays a preview image. The photographed person P presses a determination button on the touch panel 3 when accepting the image displayed on the touch panel 3. Accordingly, the process proceeds to step S105.

  On the other hand, the subject P pushes a re-photographing button on the touch panel 3 when re-photographing is desired. Thereby, the process returns to step S103.

  Note that a plurality of images may be taken in step S103, a plurality of preview images may be displayed on the touch panel 3, and an image most liked by the subject P may be selected.

  (Step S <b> 105) The selection unit 21 extracts background image data from the database 17. In addition, the image processing unit 22 uses a process based on chroma key composition to cut out a person image from the photographed image and synthesize it with the background image to create composite image data. Further, the image processing unit 22 creates preview image data from the composite image data. Here, the background image used for the composite image is any one of the background images extracted by the selection unit 21.

  (Step S106) The touch panel 3 displays the composite image created in step S105. The touch panel 3 displays background image data as background image candidates. For example, as illustrated in FIG. 5, the composite image 31 and the background image candidate 32 are displayed on the touch panel 3.

  (Step S <b> 107) When the subject P accepts the composite image displayed on the touch panel 3, he presses a determination button on the touch panel 3. Accordingly, the process proceeds to step S111. If the background image is to be changed, the process proceeds to step S108.

  (Step S108) When a background image is selected from the background image candidates displayed on the touch panel 3, the process proceeds to step S109. If the background image candidate displayed on the touch panel 3 does not include a background image that suits the subject P and the background image is custom-created, the process proceeds to step S110.

  (Step S109) The subject P selects one background image from the background image candidates. The image processing unit 22 synthesizes the person image cut out from the photographed image and the selected background image to create composite image data. Then, the newly created composite image is displayed on the touch panel 3.

  (Step S110) The subject P selects a color, a pattern, etc., and creates a custom background image. For example, as shown in FIG. 6, a color chart (hue ring) 33 is displayed on the touch panel 3, and the subject P can select any color. In addition, the subject P can select a pattern, gradation, and the like.

  The custom background creation unit 23 creates a custom background image from the color or pattern selected by the subject P. The image processing unit 22 synthesizes the person image cut out from the photographed image and the custom background image to create composite image data. Then, the newly created composite image is displayed on the touch panel 3.

  (Step S111) The image processing unit 22 extracts a portion having the same color as the background color (wallpaper color) in the photographed image from the person image cut out from the photographed image in Step S105, and uses the extracted portion as the background color. Convert to the complementary color or white. Then, the image processing unit 22 combines the person image after the color conversion (background color converted person image) and the background image used for the composite image approved by the subject P in step S107, to obtain the background color. Create converted composite image data.

  (Step S112) The touch panel 3 positions the composite image (first preview image) approved by the subject P in step S107 and the background color conversion composite image (second preview image) created in step S111 at the same position. Are displayed alternately. As a result, the background color (wallpaper color) remaining without being cut out is displayed in a flash manner. In the background color conversion composite image, since the background color portion is a complementary color of the background color or white, the difference between the composite image and the background color conversion composite image is easily visible. Further, since the touched area is displayed in an enlarged manner when the subject P touches the image display area on the touch panel 3, the difference between the composite image and the background color conversion composite image in a fine part such as a hair tip is also visually recognized. It has become easier.

  (Step S113) If the subject P confirms the composite image and the background color conversion composite image that are alternately displayed on the touch panel 3, and determines that the cut-out process of the person image is correctly performed, the touch panel 3 is pressed, and the process proceeds to step S114.

  On the other hand, if it is determined that the person image is not accurately cut out and the background color remains in the person image, the re-execute button on the touch panel 3 is pressed, the process returns to step S103, and the shooting is started again.

  (Step S114) The image processing unit 22 creates print image data from the composite image data. Then, the printer 5 receives the print image data from the arithmetic and control unit 1, prints the composite image on paper, and outputs it.

  As described above, according to the present embodiment, the background image in the person image clipped from the photographed image and the composite image obtained by combining the person image clipped from the photographed image with the background image desired by the user (photographer P). The (wallpaper color) portion is color-converted to a complementary color of the background color or white, and a background color conversion synthesized image obtained by synthesizing the background image is alternately displayed. As a result, a different part between the synthesized image and the background color conversion synthesized image, that is, the background color (wallpaper color) remaining in the person image is displayed in flash, and the process of cutting out the person image from the photographed image is accurately performed. It can be easily confirmed whether or not it has been performed. In addition, since it is possible to confirm whether or not the person image has been correctly cut out before print output, the user can obtain an appropriate print.

  Further, according to the present embodiment, even if there is no background image that suits the user's preference among the background image candidates, a background image that suits the user's preference can be created by creating a custom background.

  In the above-described embodiment, the composite image and the background color conversion composite image are alternately displayed. However, the composite image and the background color conversion composite image may be displayed in the vertical and horizontal directions at the same time for comparison.

  Further, in the above embodiment, when the person image cropping process has failed (No in step S113 in FIG. 4), the process returns to step S103 and starts again, but the chroma key process is performed as in the flowchart shown in FIG. It is also possible to change the parameters when cutting out the person image in (Step S115), and return to Step S105 and start again from the cutting out of the person image. In changing the parameter, for example, a color range regarded as a background color (wallpaper color) is expanded.

  When the loop process from step S113 to step S103 in the flowchart of FIG. 4 or the loop process from step S113 to step S105 in the flowchart of FIG. May select and extract a background image having a color close to the background color (wallpaper color) from the database 17, and display it as a background image candidate in step S106 of the flowcharts of FIGS. When the subject P selects a background image from the displayed background image candidates, the background color portion does not stand out in the composite image even if the background color remains in the person image.

  In the above embodiment, when creating a custom background, as shown in FIG. 8, the color of clothes, the color of hair, the color of skin, etc. may be plotted on the color chart 33. It is difficult for the user to accurately determine where the clothes color, hair color, and skin color are located on the color chart. The user considers the position of the user's clothes color, hair color, and skin color plotted on the print production apparatus, and creates a background image that suits his / her preference while clarifying the person image. Can do.

  The user may touch his / her clothes or hair in the preview image on the touch panel 3 and plot the color of the touched part on the color chart. In this case, the color of the part touched by the user is extracted by the image processing unit 22.
