Definitions

  • the invention relates to an image display / recording device which has both a screen, in particular a flat screen, and a camera, such as a semiconductor camera.
  • an image display / recording device with a flat screen attached to a screen support housing, which support housing also contains a screen control circuit, a semiconductor camera, a camera control circuit and camera optics.
  • the image display / recording device according to the invention with the camera integrated in the screen support housing and its optics as well as control electronics can be produced inexpensively and can be installed in a space-saving manner. It is also possible to place the camera at a short distance from the screen, which makes a screen dialog much easier.
  • the screen control circuit and camera control circuit are preferably implemented in a common electronics module on a single printed circuit board. This results in further space and cost savings.
  • All electrical components of the image display / recording device according to the invention preferably have a common power supply. This reduces the susceptibility to electromagnetic interference since there is no need for separate camera cabling.
  • Flat screen and semiconductor camera can be aligned horizontally or vertically to one another in a simple manner. It is particularly disadvantageous to align the camera to the central axis of the transverse side of the screen, since the camera is then arranged as close as possible to the center of the flat screen. This facilitates a screen dialog, for example for a video telephone or an intercom.
  • the image display / recording device can also have an optical deflection device such as a prima, mirror or light guide, so that the camera no longer has to lie in the optical axis of the lens. This makes it possible to mount the camera lens in other directions or to make it pivotable in the vertical axis.
  • the flat screen can be an LCD, TFT or STN screen and the semiconductor camera can be a CCD camera or a CMOS camera.
  • the image display / recording device can be used for video telephones, multimedia computers, intercom systems with image transfer function in the security area or for camcorders or digital cameras.
  • FIG. 1 shows a perspective view of an exemplary embodiment of the image display / recording device according to the invention
  • Figure 2 is a cross-sectional view of the device of Figure 1 along the line A-B in Figure 1, and
  • FIG 3 is a cross-sectional view of a second exemplary embodiment of the image display / recording device according to the invention along the line A-B, but with an additional optical deflection device 7 and, alternatively, a camera lens rotated by 180 °.
  • FIG. 1 schematically shows a perspective view of an exemplary embodiment of an image display / recording device according to the invention, which is designated overall by reference number 1.
  • a flat screen 2 is attached to a carrier housing 3 such that the active image area of the screen 2 is visible to the viewer.
  • the cross-sectional line AB through the screen narrow side represents the optical axis of the screen 2, to which the camera 4 is aligned. With this arrangement, the camera can get as close as possible to the center of the screen 2. are brought so that the user of the device according to the invention also looks in the direction of the camera 4 when looking at the screen 2.
  • FIG. 2 is a cross-sectional view of the image display / recording device according to the invention along the line A-B of FIG. 1.
  • Both the control electronics for the screen 2 and the camera 4 are accommodated on a circuit board 6. Since the space requirements for camera electronics have recently been significantly reduced by technical advances, compact housing of the camera electronics is possible.
  • the camera 4 itself consists of a CCD (charge coupled device) camera or a CMOS (complementary metal oxide semiconductor) camera, which is characterized by small dimensions.
  • Camera optics 5, such as an objective lens are mounted in front of the camera 4.
  • a pivotable objective lens, deflection optics 7 or an optical fiber can be provided for coupling light in order to record images from directions other than those of the screen. This variant is particularly advantageous for use in camcorders or digital cameras, where the screen 2 forms the viewfinder and the optics 5 are used for image recording.
  • Assemblies d. H. the screen itself, its control as well as the camera and the camera electronics on a power supply unit. This eliminates the need for separate camera cabling, which reduces the sensitivity to electromagnetic interference, for example due to high-frequency waves.
  • the image display / recording device thus provides a space-saving and inexpensive device for carrying out a screen dialog, which is particularly suitable for use in video telephony, multimedia computers, intercom systems or the like.
  • suitable microphone and loudspeaker devices can also be accommodated in the housing 3.
