  The best mode for carrying out the present invention will be described below with reference to the embodiments shown in the drawings.

  FIG. 1 is a conceptual diagram showing the system configuration of the first embodiment of the present invention. The apparatus of the present embodiment is generally composed of a computer 1, coordinate input means 2 as an input device for the computer 1, and display means 3 as an output device.

  The computer 1 does not have to be special, and may be anything that can execute a program according to the present invention described later. In the illustrated example, it is drawn as a so-called notebook personal computer type, but is not limited thereto.

  As the coordinate input means 2, it is possible to employ various known devices (hereinafter referred to as an input board) 4 such as a board or sheet capable of so-called handwriting input and an input device 5 such as a pen. As the input board 4, a matrix touch panel capable of detecting a so-called coordinate input is suitable. In the illustrated embodiment, the input board 4 is preferably transparent so that the display content of the monitor 6 can be visually recognized from the outside because it is used in the form of being superimposed on the monitor 6 of the computer 1. Further, in the illustrated example, a sensor 7 for detecting and recognizing the movement of the input device 5 is attached to a side portion of the monitor 6. Also for this, for example, a USB cable or any other suitable connection form that can be connected to the computer 1 is known, and this may be adopted.

  As the display means 3 as an output device, various known devices such as a so-called projector screen and a large-screen liquid crystal display device can be adopted. In the illustrated example, a signal line is connected from the computer 1 to the display means 3. However, when a projector screen is used, the projector is connected to the computer 1. It will be a light beam to be emitted. Therefore, it is not limited to the linear connection form as shown in the figure.

  FIG. 2 is a functional block diagram of the present embodiment. The computer 1 includes a video signal supply unit 8 and an image composition output unit 9 and also includes a handwritten display image forming unit 10 as a complementary functional part of software and hardware.

  The handwritten display image forming unit 10 is a coordinate locus detecting unit 11 that detects an input from the coordinate input unit 2, that is, a coordinate locus about the movement of the input device 5 on the input board 4, and the connection of the input device 5 to the input board 4. A contact / separation state detection unit 12 for detecting a separation state (at least a separation time), a timer 13 for setting a control time described later, and a handwritten display image for outputting a handwritten display image to the image composition output means 9 An output unit 14 is provided.

  That is, in this embodiment, for example, a handwritten image can be superimposed or synthesized by handwriting during the presentation on the content for presentation created using, for example, Microsoft PowerPoint (registered trademark) and stored in the computer 1 By installing a simple software in the computer 1, it is possible to make a presentation with handwriting easily and to superimpose or combine after the set time elapses by setting the timer 13 (for example, 1 second to 8 seconds). The handwritten image is automatically erased from the content image for presentation. To erase the handwritten image, no separate button operation, key operation, or the like is necessary, and it depends on the timer setting.

    For example, when the contents indicated by A and B in the drawing are added to the presentation screen as shown in FIG. 3, that is, when there are a plurality of points to be emphasized and pointed out to the audience on the same screen of the presentation, it is conventional. For example, the handwriting indicated by A in the figure had to be erased by some other operation and then handwritten in B in the figure had to be performed. As time goes by, A disappears automatically. Therefore, the performer can write by hand B in the following figure without being aware of the operational feeling, and can concentrate on the lecture. The speaker simply needs to switch to the next presentation screen. Accordingly, the number of seconds for setting the timer 13 may be appropriately determined by the speaker in consideration of his / her own habit. If A and B are to be handwritten at the same time on the same screen, after writing A in the figure, the pen tip is kept in contact with the screen and handwritten in the figure B as it is. If you set the time from when you release the handwriting to the disappearance of the handwritten content to an appropriate time, even if you release the pen tip after entering A and then enter B, it will be possible. Moreover, even if the handwritten input disappears while still necessary, it can be rewritten. It may be possible to appeal to the audience.

  In FIG. 3, a matrix panel is used as the input board 4. However, the present invention is not limited to this, and various input panels, boards, sheets, and the like can be used.
