Embodiment
A. the configuration of the projection lens of projecting apparatus and built-in camera
Fig. 1 is the main view for showing to be provided with the state of the first projection lens 210 for projecting at a distance in projecting apparatus 100
Figure, Fig. 2 is Fig. 1 viewed from above perspective view.The first projection lens 210 is provided with the front panel 110 of projecting apparatus 100 and right
It is projeced into two built-in cameras 310,320 that the image of projection surface is shot.First projection lens 210 is can change
Mode is arranged on lens installation portion 230.As shown in Fig. 2 the lens barrel of the first projection lens 210 protrudes overhang from front panel 110
D1。
First video camera 310 is the first camera section for longshot, and the second video camera 320 is to be used to closely take the photograph
The second camera section of shadow.The video camera 310,320 preferably has more than one difference in following (1)~(3), and following (1) are
Most typical difference.
(1) angle of visual field θ 2 (Fig. 2) ratios for the second video camera 320 of close-range photography are used for the first of longshot
The angle of visual field θ 1 of video camera 310 is wide.
(2) it is used for the focal position of the second video camera 320 of close-range photography than the first photography for longshot
The focal position of machine 310 is near.
(3) resolution ratio for the second video camera 320 of close-range photography is used for the first video camera of longshot
310 resolution ratio is low (pixel count is few).
The first video camera 310 for longshot is configured to hang down in the optical axis CX relative to the first projection lens 210
Directly on optical axis CX direction separated first apart from L1 position.The second video camera 320 for close-range photography is configured in phase
For the first projection lens 210 optical axis CX on the direction perpendicular to optical axis CX second distance of the splitting ratio first apart from L1 length
L2 position.Its reason is described below.
Fig. 3 is the main view for showing to be provided with the state of the second projection lens 220 for short range projection in projecting apparatus 100
Figure, Fig. 4 is Fig. 3 viewed from above perspective view.As shown in figure 4, the lens barrel of the second projection lens 220 is protruded from front panel 110
Overhang D2.In typical example, the overhang D2 ratios for the second projection lens 220 of short range projection are used for remote
The overhang D1 (Fig. 2) of first projection lens 210 of projection is big.Its reason be with shorter apart from the second of projects images
The aperture of lens of the projection lens of projection lens 220 to the first 210 is big, and there is also elongated trend for lens barrel.
As described above, the second video camera 320 for close-range photography is configured than being taken the photograph for the first of longshot
Shadow machine 310 is further from the position of projection lens 210,220.Its reason is the second video camera 320 for being generally used for close-range photography
The angle of visual field than the first video camera 310 for longshot, with a wide angle of view, therefore, if the second video camera 320 is configured
In the position close to projection lens 220, then the lens barrel of projection lens 220 can enter the angle of visual field of the second video camera 320, therefore can
The entirety of projects images on screen cover can not can be shot.Can be to the whole of the projects images on screen cover in addition, working as
When body is shot, if the lens barrel of projection lens 220 enters the angle of visual field of the second video camera 320, it is likely that cause projection
The lens barrel reflection exterior lights of lens 220 and incident second video camera 320 of the reflected light, and produce in photographed images larger make an uproar
Sound.The possibility that these undesirable conditions are produced is used in the overhang D2 ratios of the second projection lens 220 for short range projection
In the case that the overhang D1 (Fig. 2) of the first projection lens 210 projected at a distance is big, or the second projection lens 220 mouth
It is more notable in the case that footpath is bigger than the bore of the first projection lens 210.Here, projecting apparatus 100 front panel 110 it is limited
Space in, while design is considered, and in order to which above-mentioned influence is limited into minimum, with first for longshot
Video camera 310 is compared, and the second video camera 320 for close-range photography is configured at into the optical axis apart from projection lens 210,220
Position farther CX.
In addition, when changing distance (projection distance) of projecting apparatus 100 and projection surface, video camera 310,320 is configured to
Optical axis CX apart from projection lens 210,220 is more remote, then the change of the position of the projects images in photographed images is bigger.However,
Configuration is in the visual field of the second farther the optical axis CX apart from projection lens 210,220 video camera 320 compared with the first video camera 310
Angle because than the first video camera 310, with a wide angle of view, even if therefore projects images in photographed images change in location, also can
It is contained in the angle of visual field.
Can be the example such as Fig. 1~Fig. 4 each other in transverse direction in addition, as the allocation position relation of video camera 310,320
(horizontal direction) is configured in the way of arrangement, or can also be configured centered on the optical axis CX of projection lens 210,220
The optional position of the position of concentric circles etc.., can also be with addition, in the case where projecting apparatus sets the video camera of more than three
The mode that the wider video camera of the angle of visual field is configured in position more remote the optical axis CX apart from projection lens 210,220 is configured successively.
In addition, projection lens 210,220 lens barrel enter video camera 310,320 the angle of visual field in the case of, preferably with
The relatively low material of reflectivity (such as diffuse-reflective material with fine irregularities) makes the lens barrel of projection lens 210,220.
Additionally, it is preferred that the configuration of video camera 310,320 is in the optical axis CX of projection lens 210,220 top.Its reason is, when
If projecting apparatus 100 be placed in, desk etc. is upper in use, video camera 310,320 is configured in downside, and desk etc., which can enter, to be taken the photograph
In the angle of visual field of shadow machine 310,320, therefore there is a possibility that the entirety of the projects images on screen cover can not be shot.
In addition, in the case where that can be shot to the entirety of projects images, if desk etc. enters the visual field of video camera 310,320
Angle, then reflect the incident video camera 310,320 of exterior light and the reflected light in desk etc., then exist produced in photographed images it is larger
Noise possibility.Especially, the second video camera 320 that with a wide angle of view, it is easier to produce this undesirable condition, therefore,
The second video camera can be configured in the position of the top of the first video camera 310.
Fig. 5, Fig. 6, Fig. 7 are the figures of the various examples for the outward appearance for showing the first video camera 310 and the second video camera 320.
In the example, by the outward appearance of the first video camera 310 for longshot and the second video camera 320 for close-range photography
It is set to the video camera that can be easily recognized with naked eyes each other.Consequently, it is possible to when any video camera in video camera 310,320 is produced
