Description

  The present invention relates to an image composition system, and more particularly to an image composition system that creates a composite image using a chroma key.

  Conventionally, image composition in an electronic image is performed by photographing a main subject against a blue single-color background (commonly known as a blue back) that is a complementary color of skin color, and using a blue background image excluding the main subject as a normal background image ( A so-called chroma key composition process is performed in which the main subject image and the normal background image are combined by replacing the normal background image).

  In such chroma key composition processing, even if the person who is the main subject and the background are continuous, the shadow of the person is erased, giving an unnatural impression, but the image data of the shadow part is There is known a synthesis method in which background image data in which a shadow of a main part is added to an image after using it is created (for example, Patent Document 1).

  In addition, by making the inside of the back of the device casing and the bottom of the interior itself emit light, and by projecting illumination from the front and ceiling to the subject, the shadow of the whole body of the subject to be shot is canceled, creating a shadowless state An image composition method is known that obtains a natural composition result in a limited space with a simple structure and a small occupation space (for example, Patent Document 2).

  In addition, by freely changing the background color according to the color used for the subject, and selecting and displaying a desired color not used for the subject as the background color, the subject image and the desired background image are displayed. A background device that contributes to performing high-precision synthesis processing when synthesizing using chroma key synthesis processing is known (for example, Patent Document 3).

In addition, by using a reflected light guide sheet that guides the reflected light reflected by the illumination light of the lighting strobe to an area other than the area where the camera is located, it is used as a screen as a background of the subject. 2. Description of the Related Art A photographic print creating apparatus capable of preventing halation and obtaining a beautiful photographed image is known (for example, Patent Document 4).

  The image composition system of the present invention is used in a theme park or the like, for example, when a person image is synthesized with a background image on which a castle or a building and a character are displayed. The system can also be used. Hereinafter, embodiments of the present invention will be described in detail.

  In FIG. 1 showing the first embodiment of the present invention, an image composition system 10 includes a translucent screen 12 made of a well-known lenticular lens disposed behind a person 11 as a main subject, and a surface 12a of the screen 12. A digital camera 15 that takes a picture of a person 11 against a background, two first and second projectors 16 and 17 installed behind the back surface 12b of the screen 12, and the digital camera 15 and the first and second The system controller 18 (refer FIG. 2) which controls the projectors 16 and 17 is comprised. Although not shown, at the time of shooting, the strobe device emits light to illuminate the person 11 in synchronization with the shutter release of the digital camera 15.

  The screen 12 is drawn in the shape of a waveform in order to schematically represent that it is composed of a lenticular lens in the drawing, but actually, for example, the screen 12 has a pitch of cylindrical concave lenses having a width of 40 lpi (line per inch). Uses fine details.

  The first projector 16 projects a normal background image 22 (see FIG. 3A) on which the photographed image of the person 11 is to be combined onto the back surface 12 b of the screen 12. The normal background image 22 can be freely determined according to the user's preference. For example, a background image on which a castle, a building, and a character are displayed is used. Further, the normal background image 22 is a negative image with respect to the back surface 12b so as to be a normal image when viewed from the front surface 12a of the screen 12.

  The second projector 17 projects a single color background image 23 (see FIG. 3B) composed of a single color used for the well-known chroma key composition process onto the back surface 12b of the screen 12. Note that the color of the single-color background image 23 is “gray” in the present embodiment.

  The first and second projectors 16 and 17 are spaced apart from each other at symmetrical positions with respect to the virtual center line L1 drawn vertically from the center of the back surface 12b of the screen 12, and an image is displayed on the entire back surface 12b of the screen 12. The direction of each projection optical axis is determined so as to be projected. The first and second projectors 16 and 17 simultaneously project the normal background image 22 and the single color background image 23, respectively.

  When the surface 12a of the screen 12 is viewed from the side on which the person 11 stands, an image that can be seen on the surface 12a of the screen 12 is usually changed by slightly changing the desired angle of the surface 12a of the screen 12 due to the characteristics of the lenticular lens. The background image 22 or the single color background image 23 is switched to. The digital camera 15 is installed at a position where the single color background image 23 can be seen on the surface 12 a of the screen 12.

  In FIG. 2 showing the electrical configuration of the image composition system 10, the system controller 18 includes a single color background / selection unit / display unit 26, a normal background / selection unit / display unit 27, a subject cutout unit 28, and an image composition unit. 29. A user selects in advance image data (hereinafter referred to as single color background image data) of a color (in this embodiment, gray) having a hue different from the color of clothes or shoes worn by the person 11, and a single color background / selection unit. / Set on display 26. Further, image data of a desired normal background image to be combined with the person 11 (hereinafter referred to as normal background image data) is selected and set in the normal background / selection unit / display unit 27.

  When the system controller 18 is turned on, the single color background / selection unit / display unit 26 sends single color background image data of a preset color to the second projector 17 and single color information for creating a chroma key. To the subject cutout unit 28. Further, the normal background / selection unit / display unit 27 sends the normal background image data set in advance to the first projector 16 and the image composition unit 29.

  The subject cutout unit 28 generates a key signal based on the single color information (color information) input from the single color background / selection unit / display unit 26, and thereby photographic image data input from the digital camera 15. The photographed image data of the person 11 (hereinafter referred to as main subject image data) is cut out from the image data, and the main subject image data is sent to the image composition unit 29.

  The image composition unit 29 synthesizes the main subject image data and the normal background image data sent from the normal background / selection unit / display unit 27, and uses the obtained image data as print image data in a printer ( (Not shown). Note that the main subject image data clipped from the captured image data retains coordinate data in the captured image, and is combined at the same coordinate position in the normal background image when combined with the normal background image data. .

  Next, the operation of this embodiment will be described. First, a single color background image 23 having a color as different as possible from the color of clothes, shoes, etc. worn by the person 11 in advance is selected, and the single color background image data is stored in the single color background / selection unit / display unit 26. set. The color of the single color background image 23 is gray in this embodiment. Further, a desired normal background image 22 to be combined with the photographed image of the person 11 is selected and set in the normal background / selection unit / display unit 27.

  When the digital camera 15, the first and second projectors 16 and 17, and the system controller 18 are powered on, the single color background / selection unit / display unit 26 supplies the single color background image data to the second projector 17 and the single color. Single-color background information that is color information of the background image 23 is sent to the subject cutout unit 28. At the same time, the normal background / selection unit / display unit 27 sends the normal background image data to the first projector 16 and the image composition unit 29.

  As shown in the flowchart of FIG. 4, the first and second projectors 16 and 17 project the normal background image and the single color background image onto the back surface 12b of the screen 12, respectively (st1). The user stands at a position where the normal background image 22 can be seen on the surface 12a of the screen 12, confirms the balance between the person 11 and the normal background image 22, and adjusts the standing position of the person 11 (st2). Thereby, an image after completion of synthesis can be predicted with high accuracy.

  Next, the user stands up to a position where the single color background image 23 can be seen on the surface 12 a of the screen 12, and checks whether the outline of the person 11 is clearly separated from the single color background image 23. (St3). When the outline of the person 11 is not clearly separated from the single-color background image 23 and cannot be seen, the outline of the person 11 is clearly obtained from the single-color background image data set in the single-color background / selection unit / display unit 26. Change to single-color background image data of another color that appears to be separated (st4).

  When the user releases the shutter of the digital camera 15 at a desired timing, the person 11 is photographed by the digital camera 15 against the background of the single color background image 23 (st5). The digital camera 15 performs various kinds of well-known image processing, outputs digital image data, and sends it to the subject cutout unit 28.

  The subject cutout unit 28 cuts out main subject image data from the image data input from the digital camera 15 based on the single color background information, and sends it to the image composition unit 29. The image composition unit 29 composes the main subject image data and the normal background image data input from the normal background / selection unit / display unit 27 (st6), and sends this image data to the printer as image data for printing. .

  Next, as shown in FIG. 5, the image composition system 30 according to the second embodiment of the present invention uses two first and second digital cameras 31 and 32, and uses two different single-color backgrounds. Thus, it is possible to cope with the case where the person 11 is photographed at the same time, and the color of an object worn by the person 11 such as clothes and shoes resembles the hue of one single color and cannot be clearly separated. In addition, the same code | symbol is attached | subjected to the same structure location as the said 1st Embodiment, and description is abbreviate | omitted. Although not shown, at the time of shooting, the strobe device emits light to illuminate the person 11 in synchronization with the shutter releases of the first and second digital cameras 31 and 32.

  In FIG. 6 showing the electrical configuration of the image composition system 30, the single color background image data sent from the single color background / selection unit / display unit 26 of the system controller 33 and the normal background / selection unit / display unit 27. The transmitted normal background image data is switched by a background image switch 35 controlled by the switching control unit 34 at a predetermined constant time interval, for example, at an interval of 1/30 seconds, and is sent to the first projector 16 and the second projector 17. Each is sent.

  As shown in FIGS. 7A and 8A, the first projector 16 alternates the normal background image 22 and the single color background image at regular intervals, and the single color background image is a single blue color image. The one-color background image 36 and the green single-color background image 38 are alternately projected on the back surface 12 b of the screen 12. Further, as shown in FIGS. 7B and 8B, the second projector 17 alternates the normal background image 22 and the single color background image at regular time intervals, and the single color background image is The green single-color background image 38 and the blue single-color background image 36 are alternately projected onto the back surface 12 b of the screen 12 so as to be a single-color background image different from the first projector 16.

  The projection timings of the projectors 16 and 17 are synchronized. When the first projector 16 is projecting the normal background image 22, the second projector 17 also projects the normal background image 22, and the first projector 16 is blue. When the single-color background image 36 or the green single-color background image 38 is projected, the second projector 17 projects the green single-color background image 38 or the blue single-color background image 36.

  The first digital camera 31 is installed at a position where the projected image from the first projector 16 is projected on the screen 12 and is photographed in synchronization with the projection timing of the first projector 16. The second digital camera 32 is installed at a position where the projection image from the second projector 17 can be seen projected on the screen 12 and shoots in synchronization with the projection timing of the second projector 17.

  As described above, the first projector 16 and the second projector 17 project the single-color background images that are interchanged with each other, and the first digital cameras 31 and 32 alternately take different single-color background images as a background. Therefore, variations in color data of the main subject image due to individual differences and combinations of projectors and digital cameras can be reduced.

  Shooting image data using the single-color background images 36 and 38 output from the first and second digital cameras 31 and 32 as backgrounds are extracted through a shooting image switching unit 40 controlled by the switching control unit 34. Sent to the unit 28. In addition, the image data of each through image with the normal background image 22 output from the digital cameras 31 and 32 as the background is sent to a monitor (not shown) via the captured image switcher 40, and the image combined state is displayed. Can be confirmed in advance.

  When the subject cutout unit 28 receives the captured image data (main subject image data) obtained by photographing the person 11 with the blue single color background image 36 as the background, the subject cutout unit 28 inputs the single color background / selection unit / display unit 26. A key signal is generated based on the blue information of the single-color background image 36, whereby the main subject image data is cut out from the captured image data and sent to the image composition unit 29. Similarly, when main subject image data is received with a green single-color background image 38 as a background, a key signal is generated based on the green information of the single-color background image 38 input from the single-color background / selection unit / display unit 26. Thus, the main subject image data is cut out from the captured image data and sent to the image composition unit 29.

  Here, for example, when the sleeve color of the person 11 is blue, in the captured image data with the blue single-color background image 36 as the background, the sleeve portion cannot be separated from the single-color background image 36, but the single-color background image 36 is green. In the captured image data with the single color background image 38 as a background, the blue sleeve portion is separated from the single color background image 38. Further, when the shoe color of the person 11 is green, the photographed image data with the green single color background image 38 as the background cannot separate the shoe portion from the single color background image 38, but the blue single color background. In the captured image data with the image 36 as the background, the green shoe portion is separated from the single-color background image 36.

  The image composition unit 29 synthesizes the main subject image data cut out from the single color background image 36 and the main subject image data cut out from the single color background image 38, so that a complete 1 without missing color data is obtained. The main subject image data is created. Subsequently, the image composition unit 29 composites the main subject image data with the normal background image data sent from the normal background / selection unit / display unit 27, and uses the obtained image data as print image data. Send to printer.

  Next, the operation of this embodiment will be described. First, the person 11 is made to stand in front of the screen 12. The first projector 16 alternates the normal background image 22 and the single color background image, and the single color background image alternately includes the blue single color background image 36 and the green single color background image 38. Are alternately the normal background image 22 and the single color background image, and the single color background image is alternately the green single color background image 38 and the blue single color background image 36 opposite to the first projector 16. Projection is performed on the back surface 12b of the screen 12 at regular time intervals.

  At this time, the first and second digital cameras 31 and 32 are in the through image shooting state, and the image data of the through image is sent to the monitor via the captured image switcher 40. As shown in the flowchart of FIG. 9, the user can clearly predict an image after completion of synthesis by observing the monitor (st11).

  When the user performs a shutter release operation, the first and second digital cameras 31 and 32 simultaneously photograph the person 11 with the blue single-color background image 36 and the green single-color background image 38 as the back at the same timing. (St12). These photographed image data are sent to the subject cutout section 28 via the photographed image switcher 40, and main subject image data is cut out from each photographed image data (st13) and sent to the image composition section 29.

  Based on the two main subject image data sent to the image composition unit 29, one complete main subject image data without missing color data is created (st14). Subsequently, the main subject image data and the normal background image data sent from the normal background / selection / display unit 27 are combined (st15), and the obtained image data is sent to the printer.

  In the present embodiment, when the first projector 16 projects the normal background image 22, the second projector also projects the normal background image 22, and when the first projector 16 projects a single color background image, The two projectors also project a single color background image. However, when the first projector 16 projects the normal background image 22 as shown in FIGS. 10 and 11, the projection timings of the projectors 16 and 17 are shifted. The second projector 17 may project a single color background image, and when the first projector 16 projects a single color background image, the second projector 17 may project a normal background image 22. The single color background image is projected between the projectors 16 and 17 so as to have different colors.

  In this way, since the normal background image 22 is projected without interruption, the person 11 can always look back and observe the background image on the screen, and the person 11 himself can adjust the image composition position. .

  Since the first digital camera 31 is synchronized with the first projector 16 and the second digital camera 32 is synchronized with the second projector 17 to perform the photographing alternately and the photographing does not take time, it is not a strobe device. It is advantageous to illuminate using a photographic light device. Note that a strobe device may be used as long as the digital cameras 31 and 32 are individually provided with a strobe device so that charging can be made in time.

  In addition, since the digital cameras 31 and 32 alternately shoot, two positions (each position where the digital cameras 31 and 32 are installed) are replaced by one digital camera instead of the two digital cameras 31 and 32. You can also take a picture while moving back and forth.

  Next, as shown in FIG. 12, the image composition system 50 according to the third embodiment of the present invention includes three first to third projectors 51 to 53 and three first to third digital cameras 55 to 55. 57, the person 11 is photographed simultaneously with three different single-color background images. As a result, even when the color of an object worn by the person 11 such as clothes or shoes resembles the hue of two single-color background images and cannot be clearly separated, it can be separated by the remaining single-color background image. In addition, the same code | symbol is attached | subjected to the same structure location as the said 1st, 2nd embodiment, and description is abbreviate | omitted. Although not shown, at the time of shooting, the strobe device emits light to illuminate the person 11 in synchronization with the shutter releases of the digital cameras 55 to 57.

  In the present embodiment, the three different colors are “blue”, “yellow”, and “green”, and the screen is formed of a lenticular lens that makes these single-color background images visible independently by slight positional changes. 59 is installed between the projectors 51 to 53 and the digital cameras 55 to 57. The person 11 as the main subject stands on the surface 59a side of the screen 59.

  The projector 52 is installed on an extension line of a virtual center line L2 drawn vertically from the center of the back surface 59b, and the projectors 51 and 53 are arranged at positions symmetrical with respect to the virtual center line L2. Further, the directions of the projection optical axes of the projectors 51 to 53 are determined so that the image is projected on the entire back surface 59b.

  In FIG. 13 showing the electrical configuration of the image composition system 50, the single color background image data sent from the single color background / selection unit / display unit 26 of the system controller 33 and the normal background / selection unit / display unit 27. The normal background image data to be sent is switched at a predetermined constant time interval by a background image switch 35 controlled by the switching control unit 34 and sent to the first to third projectors 51 to 53, respectively.

  Accordingly, as shown in FIG. 14A, the first projector 51 projects the normal background image 22 and the green single-color background image 38 alternately onto the back surface 59b of the screen 59 at regular time intervals. The second projector 52 projects the normal background image 22 and the yellow single-color background image 62 alternately on the back surface 59b of the screen 59 at regular time intervals. The third projector 53 projects the normal background image 22 and the blue single-color background image 36 alternately onto the back surface 59b of the screen 59 at regular time intervals. The projection timings of the projectors 51 to 53 are synchronized, and three normal background images 22 are projected simultaneously, and three single-color background images 38, 62, and 36 are projected simultaneously.

  The first digital camera 55 is installed at a position where the green single color background image 38 is projected on the screen 59 and the second digital camera 56 is a position where the yellow single color background image 62 is projected on the screen 59. The third digital camera 57 is installed at a position where the blue single-color background image 36 is projected on the screen 59.

  The respective photographic image data using the single-color background images 38, 62, and 36 output from the digital cameras 55 to 57 as backgrounds are converted into the subject cutout unit 28 via the photographic image switcher 40 controlled by the switching control unit 34. Sent to. In addition, the image data of each through image with the normal background image 22 output from the digital cameras 55 to 57 as the background is sent to a monitor (not shown) via the captured image switcher 40, and the state of image synthesis is displayed. Can be confirmed in advance.

  When the subject cutout unit 28 receives from the first digital camera 55 photographed image data obtained by photographing the person 11 against the background of the single color background image 38, the single color input from the single color background / selection unit / display unit 26. A key signal is generated based on the green information of the background image 38, and thereby the main subject (person 11) image data is cut out from the captured image data input from the first digital camera 55 and sent to the image composition unit 29.

  Similarly, the subject cutout unit 28 cuts out the main subject image data from the captured image data input from the second digital camera 56 based on the yellow information of the single-color background image 62, and from the third digital camera 57. Based on the green information of the single-color background image 38 from the input photographed image data, the main subject image data is cut out, and each main subject image data is sent to the image composition unit 29.

  Here, as described in the second embodiment, the first digital camera photographed against the background of the green single-color background image 38 even when the person 11 is wearing a blue object. Photographed from the third digital camera 57, which is separated by the photographed image data from 55 and photographed against the blue single-color background image 36, even if the person 11 has a green object. Separated by image data. Further, in the present embodiment, since the second digital camera 57 performs shooting with the yellow single-color background image 62 as a background, even if there is a blue or green thing worn by the person 11, The image data is separated by the captured image data from the digital camera 55.

  The image composition unit 29 creates one complete main subject image data without missing color data based on the three main subject image data cut out from the backgrounds of the single-color background images 36, 38, and 62. . Subsequently, the image composition unit 29 composites the main subject image data with the normal background image data sent from the normal background / selection unit / display unit 27, and uses the obtained image data as print image data. Send to printer.

  Next, the operation of this embodiment will be described. First, the person 11 is made to stand in front of the screen 12. The first projector 51 alternates the normal background image 22 and the green single-color background image 38, the second projector 52 alternates the normal background image 22 and the yellow single-color background image 62, and the third projector 53 normally The background image 22 and the blue single-color background image 36 are alternately projected onto the back surface 59b of the screen 59 at regular time intervals.

  At this time, the digital cameras 55 to 57 are in the through image shooting state, and the image data of the through image is sent to the monitor via the captured image switcher 40. As shown in the flowchart of FIG. 15, the user can clearly predict the image after completion of the synthesis by observing the monitor (st21).

  When the user performs a shutter release operation, the digital cameras 55 to 57 photograph the person 11 with the green single-color background image 38, the yellow single-color background image 62, and the blue single-color background image 36 in the background at the same timing. Are simultaneously performed (st22). These photographed image data are sent to the subject cutout unit 28 via the photographed image switcher 40, and main subject image data is cut out from each of the photographed image data (st23) and sent to the image composition unit 29.

  Based on the three main subject image data sent to the image composition unit 29, one complete main subject image data without missing color data is created (st24). Subsequently, the main subject image data and the normal background image data sent from the normal background / selection unit / display unit 27 are combined (st25), and the obtained image data is sent to the printer.

  In the present embodiment, the three projectors 51 to 53 project the normal background image 22 and the single-color background image alternately, but as shown in FIGS. 16 and 17, two projectors ( For example, the first and third projectors 51 and 53) project different single-color background images, and the remaining one projector (for example, the second projector 52) continuously projects the normal background image 22. Also good.

  More specifically, as shown in FIGS. 17A and 17C, the first and third projectors 51 and 53 include a blue single color background image 36, a green single color background image 38, and a yellow color. While the first projector 51 is projecting the green single color background image 38 sequentially with the single color background image 62 at a predetermined fixed time interval, the third projector 53 displays the blue single color background image 36. While the first projector 51 is projecting the yellow single color background image 62, the third projector 53 projects the green single color background image 38, and the first projector 51 is the blue single color background image. While projecting 36, the third projector 53 shifts so as to project a yellow single-color background image 62 and projects it onto the back surface 12 b of the screen 12.

  Further, as shown in FIG. 17B, the second projector 52 projects the normal background image 22 onto the back surface 12b of the screen 12 at a speed of 30 frames / second, and the second digital camera 56 synchronizes with this. A person 11 is filmed. In this movie shooting, a light device is used instead of a strobe device. Movie shooting is movie shooting at 30 frames / second.

  In addition, the first digital camera 55 performs shooting at 15 frames / second in synchronization with the projection timing of the first projector 51. The third digital camera 57 performs shooting at 15 frames / second in synchronization with the projection timing of the third projector 53 and the shooting timing of the first digital camera 55. In the photographing with the digital cameras 55 and 57, the strobe device is synchronized to perform strobe photography.

  The movie image output from the second digital camera 56 is sent to the monitor via the photographic image switcher 40, and the state of image synthesis can be confirmed in advance. Further, the main subject image is cut out based on the photographed image data output simultaneously from the first and third digital cameras 55 and 57. As shown in FIGS. 17A and 17C, this cut-out is performed by using a yellow single color background image 62 and a green single color background image 38, a green single color background image 38 and a blue single color background image 36, A combination of the blue single-color background image 36 and the yellow single-color background image 62,... Is performed to create a main subject image having no omission, and this is synthesized with the normal background image 22. As a result, variations in color data of the main subject image due to individual differences or combinations of projectors and digital cameras can be reduced.

  In the second embodiment described above, the colors of the single-color background images projected by the first projector and the second projector are interchanged and projected, but it is not always necessary to interchange them. In the second embodiment, two digital cameras are used. However, when a person is stationary, shooting may be performed by alternately changing the position with one digital camera. In the third embodiment, three digital cameras are used. However, when a person is stationary, shooting may be performed by sequentially changing the position with one digital camera.

  In the second embodiment, the colors of the single-color background image are “blue” and “green”. In the third embodiment, the colors of the single-color background image are “blue”, “green”, and “yellow”. However, the present invention is not limited to this, and any color may be used as long as the main subject image can be clearly separated. In the third embodiment, the single-color background image has three different colors. However, the present invention is not limited to such a number of colors, and may be, for example, four different colors.

  In addition, the above embodiments are all image synthesis systems operated by the user, but in addition to this, a desired background image or character is selected along a guidance screen on which a person to be photographed is displayed on the display Alternatively, the images may be automatically combined to obtain prints or image combination data. Also in this case, the image composition position can be arbitrarily selected by looking back and observing the background image on the screen.
