Description

  The present invention relates to an OSD (On Screen Display) display in an image display apparatus such as a projector.

  In recent years, there have been increasing opportunities to handle image display devices such as projectors for home theater use at home and for meetings and presentations. In addition, AV equipment and information equipment are becoming more diversified, higher performance, and multifunctional, and examples of possessing a plurality of one type of equipment such as VTRs and personal computers are increasing. In addition, the number of devices with many output signals has increased due to the digitization of devices. For this reason, it is necessary to connect an image display device such as a projector to such various devices, and therefore, the number of input terminals provided is increasing.

  Under such circumstances, connection to various devices with respect to a large number of input terminals and switching of video input signals have become very difficult to handle with the conventional technology.

As a solution to this, for example, when the video input terminal has three input terminals of an RGB input terminal, a VIDEO input terminal, and an S-VIDEO input terminal, the user toggles RGB → VIDEO by pressing an input switching button. → S-VIDEO and input signals can be switched. At this time, as information on which video signal is output on the screen of the image display device, the video signals of “RGB”, “VIDEO”, and “S-VIDEO” are displayed. The name is displayed on the output screen. With respect to the name display displayed on the output screen when such input switching is performed, video apparatuses that allow the user to arbitrarily set the name display are described in Patent Document 1 and Patent Document 2.
Japanese Patent Laid-Open No. 7-264475 JP-A-2-283177

  However, regarding the content display of the output image as described above, it is difficult for the character information to determine whether the image desired by the user is selected, and when the user can arbitrarily set the name, it is set individually. There was also an annoyance that had to be done, and it was difficult to understand except for the person who set it.

  Also, regarding the input switching operation, it is difficult to know when the user switches to the desired video by the method of switching by pressing the input switching button, and in the case of an image display device having many input terminals, If the desired video signal is skipped, the input switching button must be pressed repeatedly until switching to the desired video, and the key operation required for selecting the input signal is troublesome.

  Further, it is impossible to determine at a glance what kind of signal is currently input to each video input terminal.

  Also, if the input terminals are not concentrated in one place depending on the device and are placed on the front and back of the device, or if the device's top and bottom may change depending on the installation position, such as a projector, Since the display is reversed, when it is difficult to visually recognize the display near the input terminal of the device itself, there is a possibility that it takes a long time to connect or it is erroneously connected.

  Therefore, the present invention uses the graphic display of the input terminal unit for displaying the content of the output image, and changes the graphic display in accordance with the installation status and connection environment of the device itself, so that the image currently arranged in the device is displayed. Easy to understand whether it is an input terminal, easy connection of equipment, and what kind of video is contained in each video input terminal is displayed as a list with still images, thumbnails, etc., improving operability An object of the present invention is to provide an image display device capable of achieving the above.

  In order to solve the above-described conventional problems, the image display device of the present invention has a conventional name display for content display of an output image and all the input terminals in the same position configuration as the video input terminal portion provided in the image display device. An OSD circuit unit for displaying a graphic image is provided, and an installation state determination unit for determining what installation environment the image display apparatus is currently in is provided. Based on the determined installation environment, the OSD circuit unit changes the graphic display. Let In addition, when the input switching operation is started, the OSD circuit unit sequentially acquires the video signals input to the video input terminals so that they can be displayed as a list with still images, thumbnails, or the like.

  As a result, the graphic display of the video input terminal changes according to the installation status of the device, and it is easy to see where the signal connected to the input terminal located on the device is output to the screen of the image display device I can judge. In addition, by displaying a list of still images, thumbnails, etc. so that you can see what the input video is in each input terminal, the user can select which terminal when selecting the video input terminal. It is also easy to determine whether or not it should be performed, and it is possible to select a desired image instead of selecting the input terminal.

  If only the input terminal is desired to be selected, only the layout information may be displayed by stopping the name display.

  As described above, the present invention uses a GUI (Graphical User Interface) to select an input signal and changes the graphic display according to the installation status of the device, thereby allowing the user to change the state of the video signal when switching the video input. Can be easily understood, and operability can be improved.

  Also, in addition to the graphic display of the input terminal, by displaying the video to each video input terminal, it is possible for the user to select the input terminal based on the video, regardless of which terminal it is, further operation It is possible to improve the performance.
