DESCRIPTION OF THE PREFERRED EMBODIMENTS Conventionally, chroma key processing has been used to generate a foreground image. In general, the “chroma key processing” is a technique of extracting a key signal based on a specific color of a foreground image and replacing a part of the foreground image with a background image (screen combining).

In order to fit a person or the like into a game screen using the chroma key method, the following processing is performed.
A specific color, usually a blue wall (blue background), is provided behind the person, and the subject is placed in front of the blue background.
A foreground image is generated by photographing with a CD camera or the like. Next, from the foreground image, the specific color blue is identified on the circuit side, and the specific color (key color) is replaced with a game image for image synthesis, and an image in which a person and a game screen are synthesized. Has been generated.

However, such a method has the following problems.

It is necessary to provide a physically colored wall on the background of the subject.

At this time, it is difficult to light the blue wall in the background of the subject because the color is developed by indirect light, and the sheet (wall) as the background is formed of a flat surface so that the light is evenly applied. It is necessary that it is done. Therefore, there is a problem that the cost is increased in order to obtain an accurate image.

When applied to amusement,
The background is often uneven, and in many cases, lighting cannot be performed sufficiently due to restrictions on the installation space and the like.

Particularly in a game machine or the like, such a wall often becomes an obstacle, and preparing a blue background leads to a limitation in the degree of freedom and design of the housing design.

Further, a key color required for synthesis,
If the color of the subject is the same color, it is not possible to accurately separate the two, so that there is a problem of limiting the color of the subject. However, when applied to amusement, it is impossible to limit the color of the clothes of the subject.

According to the present invention, it is possible to solve such a problem, and to provide a system for easily generating a foreground image in which a subject is captured without requiring a physical blue wall or the like.

This embodiment is characterized in that a photographed image supply means for supplying a first image photographing a subject at a specific wavelength other than the visible light region and a second image photographing the subject at a wavelength in the visible light region; Foreground image generation means for determining an outline of the subject based on the first image, cutting out an image within the outline of the subject from the second image, and generating a foreground image.

The foreground image is an image obtained by extracting only the subject from a normal image including the subject and the background. The foreground image is used for a process of combining a plurality of images. For example, by superimposing the foreground image on an image of a different background (background image), it is possible to obtain an image in which a subject of a certain image is combined with a background of a different image.

The photographed image supply means supplies two types of images, a first image and a second image.

The second image is for obtaining an image of a subject in a normal visible region, while the first image is for obtaining a contour of the subject.

It is preferable that the two types of images are images obtained by photographing a subject with the same object and the same angle. This is because the foreground image can be easily synthesized.

In the present embodiment, unlike the conventional chroma key processing, an image photographed at a specific wavelength outside the visible light region is used to obtain an outline of a subject. Therefore, there is no need for a wall (blue mat) with a physical color (key color) behind the subject as in the chroma key processing.
In addition, since the key color and the subject do not need to be separated when the subject image is extracted, there is an advantage that the color of the subject is not limited.

In the present embodiment, the photographed image supply means includes: first photographing means for photographing the first image; second photographing means for photographing the second image; It is characterized by including a half mirror arranged so as to split the reflected light into the first photographing means and the second photographing means.

It is preferable to use a camera capable of photographing at least the specific wavelength as the first photographing means, and a camera capable of photographing visible light as the second photographing means.

The half mirror is used for equalizing a photographing range of the first photographing means and the second photographing means, and has a function of separating visible light and light of the specific wavelength.

The photographed image supply means branches the reflected light from the subject into an optical axis containing visible light and an optical axis containing the specific wavelength by a half mirror. Then, the first image and the second image are photographed by the first photographing means and the second photographing means arranged on the respective optical axes.

[0029] The first image and the second image obtained in this way are images of the same photographing range of the subject at the same time. Therefore, it is possible to obtain an image suitable for performing a process of cutting out an image within the contour of the subject from the second image with the contour of the subject determined based on the first image.

This embodiment is characterized in that the photographed image supply means includes a filter arranged between the first photographing means and the half mirror for cutting visible light, and a filter provided between the second photographing means and the half mirror. And a filter that cuts light of a specific wavelength, which is disposed in the light source.

By splitting the light with a half mirror, light of a specific wavelength can be incident on the first photographing means and visible light can be incident on the second photographing means. However, there is a possibility that light having a wavelength other than the specific wavelength may enter the first image capturing unit other than visible light into the second image capturing unit due to an error in the spectral accuracy and transmittance of the half mirror and other causes. Therefore, by providing a filter that cuts light incident at an unexpected wavelength as in the present embodiment, it is possible to obtain more accurate first and second images.

In this embodiment, the photographed image supply means is arranged on the optical axis of the photographing means for photographing the first image and the second image, and on the optical axis of the object and the photographing means. Filter means that functions to pass only light of a specific wavelength at the timing of the first image when the photographing means is functioning to pass only light of a specific wavelength. Is photographed.

According to this embodiment, light of a specific wavelength and visible light can alternately enter the photographing means using the filter means. Therefore, the first image and the second image can be photographed by one photographing means,
It can be made inexpensively with a compact configuration.

This embodiment is characterized in that the photographed image supply means includes a light source for irradiating light of a specific wavelength toward a subject.

The light source may be located in front of the subject or behind the subject.

When the object is placed behind a subject, a backlighting state that often becomes a problem in a camera or the like can be created. In this state, the image has a pure black background on a pure white background. That is, the black portion represents the contour of the subject, and a subject-type mask (key) image is obtained. It is considered that an image of only the subject can be obtained by replacing the same image in the backlit state with the subject type.

Conversely, when the light source is placed in front of the subject, a light-up state in which the cameraman illuminates the subject can be created. Then, a mask (key) image of the subject can be obtained by using the fact that the subject becomes a white image when the light amount is increased.
In this state, the image has a pure white subject on a pure black background.

According to the present embodiment, a clearer contour image can be obtained by intentionally creating the backward state and the light-up state. In addition, such a state does not affect an image of visible light because it is created with light of a specific wavelength, and an image within a contour becomes clear.

The present embodiment is characterized in that the specific wavelength is a wavelength in an infrared region.

Infrared light is easy and inexpensive to separate, photograph, and project from visible light, and has a low possibility of adversely affecting the subject. Therefore, infrared light is suitable for the light having the specific wavelength.

This embodiment further comprises a convex mirror disposed on an optical axis connecting the photographed image supply means and a subject, and provided with a photographing hole through which the optical axis passes. The means and the convex mirror are unitized.

When using the foreground image generating apparatus of the present embodiment, when photographing a human subject, the position of the subject is checked, the posture, the expression, etc. are checked, and the eyes are adjusted in the direction of the photographing machine. Can be compatible.

Further, the configuration is low cost and simple in construction as compared with a device using a half mirror. Furthermore, the installation space can be adjusted only by changing the local ratio of the convex mirror. Also,
It is also possible for the subject to adjust the line of sight very naturally.

FIG. 1 is a functional block diagram of an image generation system that generates a composite image in which a subject and a game image are composited using the foreground image generation device of the present invention.

The present system includes a foreground image generating apparatus 100 for generating an image in which only a subject is extracted from a normal image including a subject and a background, and a background image generating means 130 for generating a game image to be combined with the subject.
And a combined image supply unit 140 for combining the obtained foreground image and background image, and an image display unit 150 for displaying the combined image on a display.

The foreground image generation device 100 includes a photographed image supply unit 110 and a foreground image generation unit 1.
20.

The photographed image supply means 110 comprises photographing means such as a CCD camera for photographing an image of a subject and an infrared projector. The captured image supply unit 110 outputs a second image including the background and the subject and a first image that is a mask (key) image for extracting the subject.

The foreground image generating means 120 generates a foreground image, which is an image obtained by extracting a subject from the background, from these two images.

Specifically, the contour of the subject is extracted based on the magnitude of the luminance signal of the mask (key) image as the first image, and is replaced with an image including the background and the subject as the second image. To create an image in which the subject is extracted.

It is preferable that the background of the foreground image generated by this process is generated so as to be treated as a transparent color. This is because game PCBs and the like generally have a concept of a transparent color, which is convenient when the obtained foreground image is superimposed on another image or when it is desired to treat only the subject as a texture.

The processing of the foreground image generating means 120 can also be performed using a commercially available chroma key device or the like. In a commercially available chroma key device, the image background may not be transparent, but in such a case, the background color may be set to a color that does not include the color information of the subject.

The present embodiment is an example of an image generation system that combines a foreground image with a game image and displays it on a display. The foreground image generation device of the present invention uses the generated foreground image in a game system. It can also be used for systems that handle as textures.

Next, a specific configuration of the photographed image supply means 110 will be described. The photographed image supply unit 110
Is the first image (hereinafter, IR image output)
) And a second image (hereinafter VR image out)
put)).

The IR image output is an image for obtaining information for cutting out the contour of the subject.
In the present embodiment, focusing on the property that an image of a black subject appears on a pure white background in a backlight state, which often causes a problem in a camera, etc.
It is configured to be used as an image output. In the light-up state, paying attention to the property that an image of a pure white subject is captured on a black background,
Image of subject in light-up state is IR image
You may comprise so that it may be used as an output.

Since a clear image of the subject is required as the VR image output, it is necessary that the VR image output be taken in a normal state, not in a backlight state or a light-up state. That is, for example, two states, a backlit state and a non-backlit state, must be created simultaneously,
It is difficult to simultaneously capture images in the two opposite states.

Therefore, the photographed image supply means 110 of the foreground image generating apparatus of this embodiment employs the following configuration.

FIG. 2 shows an example of the photographed image supply means 110 of the foreground image generating apparatus 100 of the embodiment.

The apparatus of this embodiment generates a foreground image of the subject 10, and in this embodiment, infrared rays are used as the specific wavelength.

The first and second cameras 30 and 32 are arranged orthogonally via a half mirror 40 so that their optical axes coincide with each other.

At the optical axis of the first camera 30, an infrared transmission filter 34 is provided. An infrared cut filter 36 is provided on the optical axis of the second camera 32.

Further, an infrared light transmitting device 20 is provided for projecting infrared light having a specific wavelength toward the subject 10.

The first camera 30 is a monochrome CCD camera, and is used to image the contour of the subject 10 in the infrared region. In order to efficiently capture infrared rays, a monochrome CCD camera is used in this embodiment because monochrome is more advantageous and the price is lower than that of color.

The infrared transmission filter 34 is a filter for blocking visible light. Infrared transmission filter 34
Is placed in front of the lens portion of the first camera 30 to block the visible light transmitted through the half mirror 40 or the visible light inserted from the outside from entering the first camera 30.

The second camera 30 is a color CCD camera, and is used for imaging the subject 10 in a visible light region.

The infrared cut filter 36 is an optical filter for blocking infrared rays. Since even a weak infrared ray affects the image, the infrared cut filter 3
By placing 6 in front of the lens of the first camera 32, infrared rays that have passed through the half mirror are cut off.

The infrared projector 20 is a projector that emits infrared rays. From here, infrared light is emitted toward the subject.
Because it is infrared, its presence cannot be confirmed with the naked eye. For example, the infrared projector 20 can be created by, for example, attaching an infrared transmission filter to a halogen light. When a halogen light is used, a considerable amount of far-infrared rays are generated, so that it is preferable to use a band-pass filter that cuts off far-infrared rays as an infrared transmitting filter.

The half mirror 40 is used to make the first camera 30 and the second camera 32 have the same image (projection range). Generally, the half mirror is at 45 ° to the light source.
(Reflectance) is determined by the transmittance when the light sources are arranged at the same position, and this transmittance is effective in the range from visible light to infrared light.

In the configuration of this embodiment, a cold mirror is used in order to more efficiently capture the reflected light from the subject. A cold mirror is a mirror that transmits infrared light and reflects visible light.

FIGS. 3A and 3B are views showing the arrangement of the cold mirror with respect to the optical axis and the spectral transmittance characteristics of the cold mirror. When the cold mirror 340 is arranged at an angle of 45 degrees with respect to the optical axis 310 as shown in FIG. 3A, light entering the cold mirror depends on its wavelength.
It shows the transmittance as shown in FIG. That is, in the visible light region, the transmittance is 10% or less, whereas in the infrared region, the transmittance is approximately 90%. Therefore, as shown in FIG. 3A, light on the optical axis 310 including visible light (VR) and infrared light (IR) is split into the optical axis 320 and the optical axis 330 via the cold mirror 340. The light on the optical axis 320 contains visible light (IR) at 10% or less and infrared (VR) at 90% or more. The light on the optical axis 330 is infrared (VR)
Is 10% or less and 90% or more of visible light (IR) is contained.

Referring to FIG. 2, IR image outp
The process of shooting out and VR image output will be described.

The subject 10 is irradiated with infrared rays from the infrared projector 20. Therefore, the light on the optical axis 90, which is the reflected light of the subject and the background, is light including infrared light and visible light. The light on the optical axis 90 is reflected by the half mirror 40 composed of a cold mirror and the reflected light on the optical axis 92 and the optical axis 94.
It is split into the transmitted light above. Since the cold mirror reflects visible light and transmits infrared light, the reflected light on the optical axis 92 is less than 10% of infrared light and 90% of visible light.
The light on the optical axis 94 is light containing 10% or less of visible light and 90% or more of infrared light.

The infrared transmitting filter 34 placed in front of the first camera cuts visible light transmitted through the half mirror 40 and other visible light entering from a gap. For this reason, the first camera 30 receives infrared light and captures an IR image output, which is an image in the infrared region.

The infrared cut filter 36 placed in front of the second camera cuts infrared rays reflected by the half mirror 40 and other infrared rays that have entered from a gap. For this reason, visible light enters the second camera 32, and a VR image output, which is an image in the visible light region, is captured.

In this way, the photographed image supply means can photograph the image of the subject 10 in the two states of the backlight state and the non-backlight state at the same timing, the same angle, and the same optical axis. .

The apparatus shown in FIG. 2 is configured as a unit.

It should be noted that a hot mirror can be used as the half mirror 40 by changing the arrangement of the first and second cameras 30 and 32. Hot mirror reflects infrared rays,
Since visible light is transmitted, a target image can be efficiently captured as in the case of a cold mirror.

FIG. 4 is a diagram schematically showing an image output in each process of the image generation system of FIG.

The first camera 30 of the photographed image supply means 110 outputs an IR image output 210 which is an image of the subject 10 photographed at an infrared wavelength. In addition, from the second camera 32, VR image out, which is a subject image captured at a wavelength of visible light,
put220 is output. Both images are obtained by photographing the subject 10 at the same timing, at the same angle, and on the same optical axis.

VR image output 220
Is a normal image in the visible light region including the background / subject 10. The IR image output 210 is an image in the infrared region. As shown in FIG. 4, the subject 10 is a white image having a black background and the subject 10 is a white image having luminance.
It is a mask (key) image for extracting 0.

The foreground image generation means 120 determines a pixel having a certain luminance or higher in the IR image output 210 as a display area of the subject 10, and
The subject 10 from the Image output 220
Is cut out of the display area of the foreground image 23.
Generate 0. At this time, the area other than the display area of the subject 10 is treated as a transparent color in order to more easily perform the subsequent image superimposition processing. That is,
An area other than the area cut out from the image area 210 is treated as a transparent color, and a foreground image 230 is generated. The foreground image 230 generated in this way is output to the image combining means 140.

On the other hand, the background image generating means 130 synthesizes the foreground image 230 and the game image 240, and outputs a synthesized image 250.

The image combining means 140 combines the foreground image 230 and the game image 240 to generate a combined image 250 as shown in FIG. As shown in FIG. 4, the composite image 250 is the game image 24 as the background.
0 is an image in which the subject 10 cut out from the VR image output 220 is arranged.

In this manner, the system of the present embodiment can generate a foreground image of a subject with a simple configuration without requiring a background wall such as a blue mat.

The foreground image 230 may be handled as a texture in the game system.

Further, the photographed image supply means may be configured as shown in FIGS.

FIG. 5 shows a configuration of the photographed image supply means 112 for obtaining a key (mask) image of a subject in a backlight state of infrared rays.

The same components as those of the photographed image supply means 112 in FIG. 2 are denoted by the same reference numerals, and the description of the portions having the same functions will be omitted. The difference from the photographed image supply means 112 in FIG.
It is the point behind zero. The infrared projector 20 emits infrared light toward the object from behind the object to create a backlight state of the infrared light.

The IR image output 210 output from the photographed image supply means 112 having this configuration is the same as that shown in FIG.
IR ima output from the captured image supply means 110
Contrary to the geometry output 210, the subject is black and the background is a white image having luminance. That is, in the backlight state of the infrared light, the contour of the subject emerges in black and is a mask (key) image for extracting the subject.

The photographed image supply means 112 having such a configuration
Is adopted, the foreground image generating means 12
0 is the IR image output 210,
A pixel having a luminance lower than a certain level is determined as a display area of the subject, and an image of the display area of the subject is cut out from the VR image output 220 to generate a foreground image.

The photographed image supply means 114 in FIG. 6 also has a configuration for obtaining a key (mask) image by the backlight state of infrared rays similarly to the photographed image supply means 112 in FIG. The same components as those in the photographed image supply unit 112 in FIG. The difference from the photographed image supply unit 112 in FIG. 5 is that the infrared projector 20 behind the subject 10 is a sheet that emits infrared rays as shown in FIG. When an infrared ray is projected by the infrared projector 20 as shown in FIG. 5, a large amount of infrared light is required to create a backlight state, whereas when a sheet that emits infrared rays is used as shown in FIG. The backlight state can be efficiently created.

The IR image output 210 output from the photographed image supply unit 114 having this configuration is the same as that shown in FIG.
IR ima output from the captured image supply means 110
Contrary to the geometry output 210, the subject is black and the background is a white image having luminance.

The photographed image supply means 114 having such a configuration is described.
Is adopted, the foreground image generating means 12
0 is the IR image output 210,
A pixel having a luminance lower than a certain level is determined as a display area of the subject, and an image of the display area of the subject is cut out from the VR image output 220 to generate a foreground image.

Therefore, when the infrared transmission filter 34 comes to the front of the lens of the camera 30, the camera 30 functions as an infrared camera for capturing an infrared image, and when the infrared cut filter 34 comes to the front of the lens of the camera 30, In the meantime, the camera 30 functions as a visible light camera that captures an image in the visible light region.

When the camera 30 functions as a visible light camera, if the infrared projector 20 is turned off, the infrared cut filter 36 for cutting infrared rays is unnecessary.

The optical filter slit frame 60, the infrared transmission filter 34, the infrared cut filter 36, and the motor 50 function as filter means.

FIG. 7C shows a timing chart of the vertical signal output 410, the CCD camera attribute 420, and the infrared projector output 430 in the photographing section 116 of FIGS. 7A and 7B.
