  FIG. 1 is a perspective view showing a display cover with an imaging device according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along line AA in FIG.

  The illustrated display cover 10 with an imaging device is a camera 11 (imaging device) installed on a transparent plate portion 12 that transmits the content displayed on the display surface 21 of the display 20 at a location different from the transparent plate portion 12. A substantially transparent light guiding and imaging optical system 15 for guiding and imaging the light is formed on the face of the user 200 (subject; see FIG. 3) facing the display surface 21 of the display 20. The image is taken from the front by the camera 11 through the system 15, and the transparent plate portion 12 is held by the holding portion 13 (holding means), so that it can be applied to the existing display 20 as well.

  That is, the illustrated display cover with an imaging device 10 includes a transparent plate portion 12 that transmits the content displayed on the display surface 21 of the existing display 20, and at least a part of the display surface 21 (shown in FIG. 1). A holding portion 13 that holds the transparent plate portion 12 by being held by the main body frame portion 26 of the display 20 so that the transparent plate portion 12 covers the entire area). From a camera 11 (CCD camera or CMOS camera) installed in a region different from the region and a surface 12a (front surface) opposite to the surface 12b (back surface) facing the display surface 21 of the transparent plate portion 12. The light image of the incident user 200 is guided to the camera 11 and imaged by the camera 11, at least in the region (range) in the transparent plate portion 12. A light guide forming optical system 15 formed in bright, a configuration in which a.

  Here, the display 20 visually displays an image or the like output from a personal computer (PC) (not shown). A display surface 21 formed of liquid crystal, plasma, a cathode ray tube or the like is displayed on the main body frame portion 26. It is supported and connected to the PC by a connection cord 20a having a terminal 20b.

  The transparent plate portion 12 is a band-pass filter or a low-pass filter (optical filter) that absorbs electromagnetic waves in a predetermined frequency band (mainly ultraviolet light) generated from the display surface 21 of the display 20.

  As shown in the cross-sectional view of FIG. 2, the holding portion 13 is fixed to the transparent plate portion 12, and the holding portion 13 is held by the main body frame portion 26 of the display 20, whereby the transparent plate portion 12 is displayed. The display 20 is held at a predetermined position with respect to the display surface 21.

  The light guide imaging optical system 15 has a light incident portion 15a on the surface 12a on which the optical image of the user 200 is incident, which is a substantially central portion of the region of the transparent plate portion 12, and the light incident imaging portion 15a includes a minute portion. An optical lens is provided. Furthermore, the light guide imaging optical system 15 connects the optical fiber bundle 15b for guiding the light beam that has passed through the minute optical lens to the camera 11 and the constraint guided by the optical fiber bundle 15b on the imaging surface of the camera 11. And an imaging lens 15c for imaging.

  Here, since the incident portion 15 a and the optical fiber bundle 15 b are disposed in the transparent plate portion 12, they are optically substantially transparent like the other portions of the transparent plate portion 12. Since the imaging lens 15c is disposed inside the camera 11 outside the area of the transparent plate portion 12, it does not need to be transparent, but forms an image on the imaging device (CCD, CMOS, etc.) 11a of the camera 11. From the viewpoint of preventing a decrease in the clarity of the optical image, a material that is as transparent as possible and has a small F number is used.

  The camera 11 captures an optical image projected by the imaging lens 15c, and sends the optical image captured by the imaging device 11a to an external device such as a PC (personal computer), for example, a USB connector 11c. And a connecting cord 11b.

  In this embodiment, the PC to which the camera 11 is connected is the same as the PC to which the display 20 is connected. However, the present invention is not limited to this form, and is different from the PC to which the display 20 is connected. PC or other video processing apparatus.

  When a videophone system is constructed by a PC to which the display 20 is connected, on the display surface 21 of the display 20, for example, as shown in FIG. In addition to displaying an image and displaying an image of the face 210 of the user 200 on the display (not shown) of the other party 100, the camera 11 displays the image and the voice of the call in an integrated manner. It is appropriate to connect to a PC to which 20 is connected.

  Next, with reference to FIG. 3 and FIG. 4, the effect | action of the cover 10 for display with an imaging device which concerns on this embodiment is demonstrated.

  FIG. 3 is a diagram showing a state in which the display cover 10 with the imaging device is set on the display 20 used by the user 200 as retrofitted, as viewed from the side.

  Since the transparent plate portion 12 transmits the content displayed on the display surface 21 of the display 20 in the display cover 10 with the imaging device, the user 200 can display the content displayed on the display surface 21 of the display 20. It can be visually recognized through the transparent plate portion 12.

  On the other hand, since the incident portion 15 a of the light guide imaging optical system 15 is provided at the substantially central portion of the transparent plate portion 12 of the cover 10, the face 210 of the user 200 facing the display surface 21 of the display 20. That is, the optical image of the face 210 of the user 200 facing the transparent plate portion 12 can be guided from the incident portion 15a to the inside of the optical fiber bundle 15b.

  The optical fiber bundle 15b guides the incident optical image of the face 210 to the camera 11 installed outside the range of the transparent plate portion 12, and the imaging lens 15c captures the image of the imaging device 11a of the camera 11. By forming an image on the surface, the camera 11 can take an image of the face 210 of the user 200.

  In addition, the line of sight 211a of the user 200 is directed to the display surface 21 of the display 20, and the optical image of the face 210 of the user 200 photographed by the camera 11 is such that the line of sight 211a is directed to the camera 11. This is a so-called camera-oriented image (an image facing the front), and an image facing the front can be obtained regardless of the spatial installation position of the camera 11 itself.

  Accordingly, the cover 10 is installed on each of the displays 20 and 20 'for making a videophone call, and the opponent's faces 110 and 210 photographed by the cameras 11 are displayed on the displays 20 and 20'. Thus, as shown in FIG. 5 (a schematic diagram showing a state in which the image of the face 210 of the user 200 photographed by the camera 11 is displayed on the display 20 ′ of the other party 100 in the videophone system) On the display surface 21 ′ (particularly, the region 21 a ′) of the display 20 ′ facing 100, an image of the face 210 of the user 200 with the line of sight 211 a facing the call partner 100 can be displayed.

  In addition, since the range portion installed on the transparent plate portion 12 of the light guide imaging optical system 15 is formed to be substantially transparent, the portion of the transparent light guide imaging optical system 15 is transparent to the user 200. When viewing the content displayed on the display surface 21 of the display 20 through the plate portion 12 (in the videophone, the image of the face 110 of the communication partner 100), the light guide imaging optical system 15 does not block the field of view.

  Therefore, even with the existing display 10, it is possible to realize a conversation with a natural feeling between the callers 100 and 200 by directly looking at each other's face.

  Further, since the transparent plate portion 12 is a bandpass filter or a low-pass filter that absorbs electromagnetic waves in a predetermined frequency band generated from the display surface 21 of the display 20, the electromagnetic waves emitted from the display surface 21 of the display 20 are used. It is possible to cut at the stage before reaching the face 210 of the person 200, and even if the electromagnetic wave is, for example, ultraviolet rays harmful to eyes or skin, the risk to the user 200 can be reduced.

  Note that the incident portion 15a of the light guide imaging optical system 15 is displayed on the display surface 21 of the display 20 in any part of the face 110 of the other party 100 of the videophone (particularly the pupil 111; 4), and the cover 10 preferably set in this manner guides the light image directed to the camera 11 on the face 110 of the communication partner 100 and the line of sight 211a of the user 200. Then, the optical image is formed on the camera 11, and an image can be obtained in which the line of sight 211a is directed to the face 110 (particularly the pupil 111) of the other party 100. It can be performed.

  In the display cover with an imaging device 10 according to the present embodiment, as shown in FIG. 6, the holding portion 13 changes the holding position adjustment mechanism 17 (where the transparent plate portion 12 covers the display surface 21 of the display 20). (Holding position adjusting means) is preferably provided.

  That is, the holding position adjusting mechanism 17 engages with the base 17d, the support 17c fixed to the support 17d and extending in the vertical direction, and slidable along the vertical direction of the support 17c. The horizontal base 17b extending in the horizontal direction, the horizontal base 17b engaging with the horizontal base 17b so as to be slidable in the horizontal direction, and the horizontal base 17b extending in the horizontal direction and the horizontal base 17b with respect to the support 17c. A screw 17f for preventing or allowing sliding and a screw 17e for preventing or allowing sliding of the suspension member 17a with respect to the horizontal base pillar 17b are provided, and the transparent plate portion 12 is fixed to the suspension member 17a.

  Then, by loosening the screw 17e, sliding of the suspension member 17a with respect to the horizontal base pillar 17b is allowed, and the horizontal position of the transparent plate portion 12 with respect to the base 17d can be adjusted, and the screw 17f is loosened. Thus, sliding of the horizontal base 17b with respect to the support column 17c is allowed, and the vertical position of the transparent plate portion 12 with respect to the base 17d can be adjusted, whereby the transparent plate of the display surface 21 of the display 20 can be adjusted. The area covered by the portion 12 can be arbitrarily changed. In addition, the position along each direction of the transparent plate part 12 is fixed by tightening each screw 17e, 17f.

  According to the display cover 10 with the imaging device having such a preferable configuration, the holding position adjusting mechanism 17 of the holding unit 13 changes the area covered by the transparent plate portion 12 in the display surface 21 of the display 20. The position of the transparent plate portion 12 can be changed by the position adjusting mechanism 17 to an area (in the display surface 21) that the user 200 wants to turn the line of sight 211a. Even if the area where the face 110 of the other party 100 is displayed is not always a fixed area on the display surface 21, it becomes easier to correspond to the area where the face 110 is displayed, and the software specification is supported. The degree of freedom can be increased.

  In addition, the light guide imaging optical system 15 has an incident portion 15a on which the optical image of the user 200 is incident on the surface 12a of the transparent plate portion 12 opposite to the surface 12b facing the display surface 21 of the display 20. The holding position adjusting mechanism 17 has the transparent plate portion 12 so that the incident portion 15a covers any portion of the image of the face 110 of the video phone call partner 100 displayed on the display surface 21 of the display 20. It is preferable to displace.

  According to the display cover 10 with the imaging device having a preferable configuration as described above, in the light guide imaging optical system 15, the transparent plate portion 12 is used on the surface 12 a opposite to the surface 12 b facing the display surface 21. The incident portion 15a on which the light image of the face 210 of the person 200 enters is arranged at a position covering any part of the image of the face 110 of the videophone call partner 100 displayed on the display surface 21 of the display 20. Because the holding position adjusting mechanism 17 displaces the transparent plate portion 12, an optical image of the user 200 with the line of sight 211a facing the face 110 of the communication partner 100 is guided to the camera 11, and this optical image is captured by the camera. 11 and an image in which the line of sight 211a is directed to the face 110 of the communication partner 100 can be obtained.
