Description

  The present invention relates to an illumination device that projects illumination light onto an irradiated object in accordance with a user operation.

  Conventionally, as an illuminating device that emits illumination light of an arbitrary shape, a filter called a gobo or a mask is installed in a projection device, and a projection unit that emits illumination light from the projection device is shielded. Thereby, the illumination light which passed the filter will be in the state cut out in the specific shape. Specifically, in a conventional illumination system, a filter (gobo etc.) cut out in a base shape composed of circles, triangles, squares, etc. is attached to a projection device to shape the contour of illumination light.

  In addition, in a conventional illumination system, if you want to irradiate only the object to be irradiated, adjust the projection position of the illumination light emitted from the projection device to the position of the object to be irradiated, and then roughly use the aperture function and zoom function of the projection device. The operation of matching the contour of the illumination light with the shape of the irradiated object is performed.

  Further, conventionally, there is an illumination system that performs a space effect by using a projector, which is a projection device, instead of a lighting fixture (light). The lighting fixture used for this lighting system is also called a moving projector. This moving projector emits image light as illumination light. For this reason, the shape and color of irradiation light can be freely set and changed as a moving image.

  However, even with this lighting system, when shaping the illumination light, a method is used that roughly matches the contour of the illumination light to the shape of the object to be irradiated, using the base shape, as with conventional illumination systems. Has been.

Further, conventionally, a technique described in Patent Document 1 below is known as a stereoscopic display device that can effectively express the surface texture of an object in a stereoscopic model.

  However, in the conventional illumination system described above, since the shape filter, aperture, and zoom prepared in advance are used, it is only possible to roughly match the shape of the illumination light to the irradiated object. Further, in the conventional illumination system, when it is desired to change the position or posture of the irradiated object, it is necessary to newly create a shape filter or the like, and it is not possible to easily change the effect of the irradiated object.

Similarly, by adjusting the positional relationship between the projector 2B and the camera device 3B, the projection range 20 of the projector 2B matches the imaging range 30 of the camera device 3B.

  In the illumination system, the light control unit 1 processes image data output from the projectors 2A and 2B in accordance with a user operation on the personal computer 4. Accordingly, the illumination system projects projection light from the projectors 2A and 2B so as to cover the subjects 10A and 10B with illumination light in accordance with a user operation.

That is, the personal computer 4 having both functions of the user I / F and the light control unit 1 may be used.

  The projectors 2A and 2B are installed in a predetermined space such as a show window space. In this predetermined space, irradiated objects 10A and 10B such as mannequins are installed, and the projectors 2A and 2B project projection light that covers the irradiated objects 10A and 10B with illumination light. The projection range 20 of the projectors 2A and 2B is determined by the installation position and orientation of the projectors 2A and 2B, the angle of view, and the driving angle.

  Projection light data is supplied from the light control unit 1 to the projectors 2A and 2B. This projection light data is used to determine an illumination range and a non-illumination range that are irradiated with illumination light within a predetermined projection range of the projectors 2A and 2B. The illumination range includes background light. This projection light data is generated by the user's operation on the personal computer 4 described later and the operation of the light control unit 1.

  The camera devices 3A and 3B have a predetermined space including a predetermined projection range 20 in which a spatial effect is produced by illumination light emitted from the projectors 2A and 2B as an imaging range 30. The camera devices 3 </ b> A and 3 </ b> B include a photographing unit 31 including an imaging element such as a CCD, an optical component, and the like, and a photographed image data output unit 32 that outputs photographed image data captured by the photographing unit 31 to the light control unit 1. .

  The personal computer 4 includes a display monitor (display means) 41, a keyboard 42 and a mouse 43, which are operation I / Fs, and other CPUs and memories. The display monitor 41 is supplied with captured image data captured by the camera devices 3 </ b> A and 3 </ b> B via the captured image data input unit 11 of the light control unit 1. Thereby, the display monitor 41 can present a show window space that the user intends to produce a space, for example.

  The operation I / Fs 42 and 43 are provided with a mechanism for detecting a user operation. Based on the user operation, the operation I / Fs 42 and 43 select the shape of the illumination light of the projection light from a pre-stored base shape group, and are selected. An operation signal for setting the illumination position, size, angle, and other characteristics within the projection range 20 of the illumination light having a different shape is supplied to the light control unit 1. The operation I / Fs 42 and 43 may include, for example, a touch panel mechanism built in the display screen of the display monitor 41 and an operation stick that is touch-operated on the touch panel mechanism by the user.

  As shown in FIG. 2, the light control unit 1 includes a captured image data input unit 11, a projection light data generation unit 12, a base image storage unit 13, and a projection light drawing unit 14. The light control unit 1 is configured by hardware including an I / F circuit, a CPU, a program memory, a RAM, and the like, but is illustrated as a functional block in FIG. 2 for convenience of explanation.

  The captured image data input unit 11 is connected to the camera device 3, and captured image data is supplied from the captured image data output unit 32 of the camera device 3. Since the projector 2 and the camera device 3 are positioned so that the projection range 20 of the projector 2 and the imaging range 30 of the camera device 3 coincide with each other, the captured image data is an image representing the projection range 20 of the projector 2. It has become. The captured image data is supplied to the display monitor 41 of the personal computer 4 by the captured image data input unit 11. Thereby, the video viewed from the projection range 20 of the projector 2 is presented to the user.

  The projection light data generation unit 12 is connected to the operation I / Fs 42 and 43 of the personal computer 4. The projection light data generation unit 12 generates projection light data for the projector 2 to project onto the projection range 20 in accordance with the operation signal supplied from the operation I / Fs 42 and 43.

  Here, the base image storage unit 13 stores a plurality of pieces of information on a predetermined base shape in advance. Examples of the base shape include a circle, a square, and a triangle. Then, the projection light data generation unit 12 selects which base shape from the base shape group composed of a plurality of base shapes stored in the base image storage unit 13 in accordance with the operation signal supplied from the operation I / Fs 42 and 43. It is determined. Further, the projection light data generation unit 12 recognizes the position of the selected base shape within the projection range 20 according to the operation signal supplied from the operation I / Fs 42 and 43. Here, when the operation signal specifying the position in the image displayed on the display monitor 41 by the operation I / Fs 42 and 43 is supplied, the projection light data generation unit 12 projects the projection range 20 corresponding to the position in the image. Convert to a position in. Thereby, the projection light data generation unit 12 projects the illumination light on the predetermined base shape range in the projection range 20 according to the operation signal, and projects the background light on the other range. Optical data can be generated.

  Furthermore, the projection light data generation unit 12 can set the characteristics of the illumination light including the brightness, color, color temperature, etc. of the illumination light. The characteristics of the illumination light are set by an operation signal from the personal computer 4. Furthermore, the projection light data generation unit 12 can set the size of a predetermined base shape whose position is set in accordance with an operation signal from the personal computer 4. The size of the predetermined base shape can be adjusted according to the size of the irradiated object 10 on which the illumination light is to be projected. Furthermore, in accordance with an operation signal from the personal computer 4, the projection light data generation unit 12 can adjust the angle of a predetermined base shape set according to the position of the irradiated object 10. By adjusting the triangle or square angle as the predetermined base shape, the position can be adjusted so that the base shape is covered with the irradiated object 10. Thus, the illumination system can easily set illumination light that covers the irradiated object 10 only by adjusting the position, size, and angle of the predetermined base shape according to the user's operation. A specific method of setting projection light data in the illumination system will be described later.

  The projection light drawing unit 14 performs a drawing process on the projection light data supplied from the projection light data generation unit 12 and projects the projection light from the projector 2. Here, when the projection light data is generated for each of the projectors 2A and 2B by the projection light data generation unit 12, the projection light drawing unit 14 performs a drawing process on each projection light data, Projection light is projected from the projectors 2A and 2B.

  In the illumination system configured as described above, the projection light data setting process displays a camera image 101 as shown in FIG. 3 on the display monitor 41, for example. In the following description, in order to make the description easy to understand, a case where a camera image 101 obtained by viewing the irradiated object 10 from substantially the front is displayed. The operation for setting the illumination light that covers the irradiated object 10 will be described with reference to an example in which the operation stick 44 is pressed with respect to the touch panel. The operation stick 44 is a touch pen that is touch-operated on the display monitor 41 that is a touch panel.

  The illumination system causes the display monitor 41 to display a setting image when the user selects the color of illumination light projected onto the irradiated object 10, the shape of illumination light, the size of illumination light, and the illumination position of illumination light. For example, when the setting image includes a touch panel mechanism built in the display monitor 41, as shown in FIG. 3, a camera image 101 captured by the camera device 3 and a plurality of colors for selecting the color, shape, and size of illumination light are selected. The menu group 102 includes button images. The plurality of button images included in the menu group 102 include a color selection button image 103, a shape selection button image 104, a size selection button image 105, and an effect start button image 106.

  The projection light data generation unit 12 is supplied with an operation signal in response to being pressed from the display monitor 41 with the operation stick 44 connected to the personal computer 4. This operation signal represents pressed coordinate information in the touch panel mechanism. Then, the projection light data generation unit 12 recognizes what operation has been performed from the coordinate information based on the user's operation, and determines the color, shape, size, and illumination position of the illumination light.

  Here, for example, as shown in FIG. 3, the projection light data generation unit 12 changes the shape of the illumination light to a round shape, a triangular shape, or the like based on the user operating the display monitor 41 with the operation stick 44. Selection is made from a group of base shapes stored in advance such as a rectangle. In this case, the projection light data generation unit 12 is stored in advance as image data in the base image storage unit 13 as shown in FIG. 10 in response to the selection of the shape selection button image 104 on the setting screen. A base shape candidate selection image 104 ′ showing a base shape group is displayed. Then, when an operation for selecting a portion indicating one of the base shapes in the base shape candidate selection image 104 ′ is performed using the operation stick 44, the operation is detected by the projection light data generation unit 12. The base shape of the illumination light can be determined.

  Similarly, when an operation for selecting the color selection button image 103 on the setting screen is performed and the color of the illumination light is determined, as shown in FIG. 4, among predetermined base colors set in advance, A color candidate selection image 103 ′ for selecting which color of illumination light to project is displayed. When an operation in which a portion indicating any base color in the color candidate selection image 103 ′ is selected is performed on the display monitor 41 using the operation stick 44, the operation is performed on the projection light data generation unit. 12 can be used to determine the base color of the illumination light.

  Similarly, when an operation for selecting the size selection button image 105 on the setting screen with the operation stick 44 is performed on the display monitor 41 and the size of the illumination light is determined, as shown in FIG. A size candidate selection image 105 ′ for selecting which size of the predetermined size to project the illumination light is displayed. When an operation in which a portion indicating any size in the size candidate selection image 105 ′ is selected is performed on the display monitor 41 using the operation stick 44, the operation is performed on the projection light data generation unit 12. And the size of the illumination light can be determined.

  When determining the illumination position of the illumination light, an operation in which the position in the image as the center position of the illumination light in the camera image 101 is selected using the operation stick 44 as shown in FIG. This is performed on the display monitor 41. Then, the projection light data generation unit 12 acquires coordinate information in the camera image 101 and generates projection light data for projecting illumination light to a position in the projection range 20 corresponding to the coordinate information. In addition, the projection light data generation unit 12 superimposes the illumination light images 201 to 205 on the camera image 101 with the base shape, color, and size of the illumination light set in advance with the position selected by the operation stick 44 as the center. indicate.

  In the state shown in FIG. 6, according to the operation of the operation stick 44 as described above, the round illumination light projection range 201 is set on the face portion of the irradiated object 10, and the triangular illumination is applied to the right arm portion of the irradiated object 10. A light projection range 202 is set, a rectangular illumination light projection range 203 is set on the body and the left arm of the irradiated object 10, and a long and thin rectangular illumination light projection range 204 is set on the right foot portion of the irradiated object 10, A long and thin rectangular illumination light projection range 205 is set on the left foot portion of the irradiated object 10.

  As described above, the illumination system selects the base shape of the illumination light from the predetermined base shape group set in advance according to the operation of the user, and covers the irradiated object 10 with the illumination light of one or a plurality of base shapes. Thus, the position of the base shape can be determined. As a result, the projector 2 projects projection light in which only portions corresponding to the illumination light projection ranges 201 to 205 are used as illumination light and other portions are used as background light.

  Here, the size of each illumination light projection range can be corrected according to the operation of the operation stick 44 after each illumination light projection range is set. That is, the radius of the round illumination light projection range can be changed, and the length of each side of the triangle and rectangle can be changed by operating the operation stick 44.

  In addition, the illumination system sets the illumination light projection range as shown in FIG. 6, and then rotates the illumination light projection range 202 as shown in FIG. 7 according to the operation of the operation stick 44 to create a new illumination light projection range. 202 'can be set. As a result, the illumination light projection range can be changed and correction can be easily performed so that the irradiated object 10 is covered with the irradiation light.

  At this time, the projection light data generation unit 12 generates the projection light data having the illumination light characteristics defined by the previously selected illumination light color, base shape, size, and preset brightness and color. It is. In addition, the projection light data generation unit 12 can generate projection light data having a preset color and luminance for the background portion other than the illumination light in the projection range 20. For example, the color of the background light, the brightness, and the like can be set according to the color of the wallpaper serving as the background of the irradiated object 10 and the combination of the color and contrast with the illumination light.

  As described above in detail, according to the illumination system to which the present invention is applied, the projection range 20 of the projector 2 and the imaging range 30 of the camera device 3 are made to coincide with each other, and the predetermined range set in advance according to the user's operation Only by selecting the base shape of the illumination light from the base shape group and determining the position of the base shape so as to cover the irradiated object 10 with the illumination light of one or a plurality of base shapes, Illumination light can be projected. Therefore, according to this illumination system, illumination light can be projected onto the irradiated object 10 by a simple user operation.

  Further, according to this illumination system, since the projection range 20 of the projector 2 and the imaging range 30 of the camera device 3 are matched, the captured image captured by the camera device 3 and displayed on the display monitor 41 is displayed. The illumination light having a shape along the illumination light projection range can be projected onto the projection range 20 simply by setting the illumination light projection range. Therefore, according to this illumination system, the illumination light set by looking at the display monitor 41 can be projected without correcting the projection light data, and the system configuration can be simplified.

"Leakage light suppression"
As described above, since the illumination system described above projects the illumination light onto the irradiated object 10 by adjusting the size and angle of the predetermined base shape, the illumination light leaks from the irradiated object 10 and is behind Will be projected.

  On the other hand, as shown in FIG. 8, the illumination system may include a leakage light suppression unit 12 a that suppresses leakage light that leaks from the irradiated object 10 and is projected behind the light control unit 1. .

  Here, the above-described illumination system projects projection light including illumination light that covers the irradiated object 10 having an arbitrary shape. Therefore, the illumination light is outside the irradiated object 10 and is projected behind as leakage light. In view of this, the illumination system processes the projection light data generated by the projection light data generation unit 12 so that the leaked light is not conspicuous but is not generated.

  The leakage light suppression unit 12a acquires projection light data indicating illumination light and background light in which the illumination light projection range is set by the above-described user operation. The leakage light suppression unit 12a performs processing for suppressing leakage light on the acquired projection light data and supplies the processed projection light data to the projector 2.

  The leakage light suppression process of the leakage light suppression unit 12a includes correcting the projection light data so that illumination light is not projected onto an area of the irradiated object 10 that is not larger than a preset size. Specifically, as shown in FIG. 9, the illumination light is projected onto a region 10 a larger than a predetermined size in the human-type irradiated object 10, but a hand portion and a foot portion having a predetermined size or less. The illumination light is not projected on the area 10b. At this time, the leakage light suppression unit 12a recognizes a region 10b having a predetermined size or less in the irradiated object 10 from the captured image data captured by the camera device 3, and projects illumination light on the portion. The projection light data is processed so that it does not occur. Thereby, the illumination system can suppress that the illumination light projected from the projector 2 toward the irradiated object 10 leaks from the irradiated object 10 and is projected onto the background of the irradiated object 10.

  Further, as shown in FIG. 10, the leakage light suppressing unit 12 a may change the illumination effect of the illumination light projected onto the contour portion 10 c having a predetermined width in the irradiated object 10. For example, no illumination light is projected onto the contour portion 10c. Moreover, you may change the illumination effect of the illumination light of the outline part 10c vicinity of the predetermined width among illumination light projection ranges.

  Thereby, the illumination control device 1 makes the illumination light projected from the projector 2 toward the irradiated object 10 leak from the irradiated object 10 and is projected on the background of the irradiated object 10 inconspicuously. In this way, since the illumination system increases the probability of leakage light when the projection area of the illumination light is set on a thin part or a fine part of the irradiated object 10, the area 10b having a predetermined size or less is set. Exclude from the projection area of the illumination light.

  Furthermore, as shown in FIG. 11, the leakage light suppressing unit 12a may gradually change the illumination effect of the illumination light from the inside to the outside in the predetermined width of the contour portion 10d. Also by this, the illumination control device 1 makes the illumination light projected from the projector 2 toward the irradiated object 10 inconspicuously leaking from the irradiated object 10 and being projected on the background of the irradiated object 10. be able to.

  Specifically, illumination effects to be changed in the contour portion 10d include illuminance, luminance, luminous intensity, luminous flux, color temperature, color rendering, and the like. Then, the leakage light suppression unit 12a changes the illumination effect of the illumination light at the contour portion 10d so that the leakage light leaked from the irradiated object 10 is not noticeable even when projected onto the background. For example, the leakage light suppression unit 12a makes the leakage light inconspicuous by reducing the illuminance of the illumination light at the contour portion 10d of the irradiated object 10. Further, the leakage light suppression unit 12a can gradually reduce the leakage light by gradually reducing the projection area of the illumination light by increasing the width of the contour portion 10d where the illuminance is set to zero. Furthermore, the leakage light suppressing unit 12a may increase the width of the contour portion 10d until the leakage light disappears. It is desirable that the contour portion 10d set to reduce the leakage light is determined according to the reduction area of the illumination light projection region.

  Furthermore, as shown in FIG. 12, the leakage light suppression unit 12a may correct the projection light data so that the illumination light is not projected onto the acute angle portion of the star-shaped irradiated object 10. In this case, the leakage light suppression unit 12a processes the acute angle portion of the illumination light so as to round it. Thus, the acute angle portion becomes a region 10f where illumination light is not projected. In this way, leakage light is likely to occur at an acute angle portion, whereas the illumination light is rounded to suppress the generation of leakage light.

  Furthermore, the leakage light suppression unit 12a may vibrate the illumination light projected by the projector 2 with a predetermined width. Thereby, even if the illumination light which is not projected on the to-be-irradiated object 10 has generate | occur | produced as leakage light, the illumination intensity visually recognized from the user U can be made low by vibration. Therefore, according to the leakage light suppressing unit 12a, the illumination light projected from the projector 2 toward the irradiated object 10 leaks from the irradiated object and is projected on the background of the irradiated object. Can do.

  Furthermore, as a configuration for suppressing leakage light, as shown in FIG. 13, in addition to the projector 2 that projects illumination light onto the irradiated object 10, the leakage light is suppressed on the back surface 10 ′ of the irradiated object 10. A projector 2 ′ for projecting background light may be provided. As shown in FIG. 14, the projector 2 ′ is installed so that the projection range 2 a ′ is not included in the irradiated object 10. Thereby, even if the projection range 2a of the illumination light of the projector 2 deviates from the irradiated object 10 and leakage light occurs on the back surface 10 ', the leakage light can be made inconspicuous by the background light.

  The light projected onto the back surface 10 'may be an illumination effect (illuminance, luminance, luminous intensity, luminous flux, color temperature, color rendering) set so as to make the leaked light inconspicuous. For example, the projector 2 'irradiates the back surface 10' with white light or the like. Accordingly, the leakage light can be made inconspicuous by utilizing the property that the color becomes white light by overlapping the colors.

  By projecting the background light onto the back surface 10 ′ in this way, as shown in FIG. 15, the illumination light is projected onto the irradiated object 10 and then the back surface 10 ′ is projected by the projection range 2a ′ of the background light. Lighting can also be produced. In the example shown in FIG. 15, illumination effects are performed on the back surface 10 ′ of each irradiated object 10 using two projectors 2 ′. Further, in the example shown in FIG. 15, as shown in FIG. 16, the illumination effect is performed on each irradiated object 10 using two projectors 2, whereas 2 for each irradiated object 10. Illumination light can be projected on each irradiated object 10 using the projector 2 of the stand.

  The above-described embodiment is an example of the present invention. For this reason, the present invention is not limited to the above-described embodiment, and various modifications can be made depending on the design and the like as long as the technical idea according to the present invention is not deviated from this embodiment.
