A video display window, is equipped.

In the second invention, the video operation button display means of the first invention displays the video button by intuitively understandable numbers or pictorial symbols. Third
According to another aspect of the present invention, the image operating means of the first invention is a laser disc (hereinafter, LD) by the pointing device.
/ Videotape recorder (hereinafter referred to as VTR) / TV video display operation, video real-time capture, and video operation functions capable of searching the stored video. In a fourth invention, the image capturing / reading means of the first invention displays the image operation button, image table of contents (index image), confirmation that still images of the captured image are accumulated, and the pointing device. Has a function of designating the image table of contents and a search function of the accumulated video.

[0007]

According to the first aspect of the invention, since the video display device is configured as described above, the video capturing / reading means captures the video shown in the window in real time or stores it in the video storage medium. The image and data are read out and sent to the output side image display means. The video / laser disk reproducing device and the tuner control means control the tuner and the tuner control unit for controlling the tuner, and send the output to the video display means. The image display means uses a tuner and a tuner control unit for controlling the tuner, and a TV
Allows video display and operation. Further, the video operation button display means displays a video operation button for changing the TV channel, a video operation button for switching from the TV video to the VTR video, etc.
Operate V / VTR video.

According to the second aspect of the present invention, the video operation button display means is a numeral or a general function of the video operation button found in a home VTR / LD reproducing apparatus, or an intuitively understandable pictorial symbol. To display the video operation button. This allows an easy-to-understand user interface without requiring special knowledge.

According to the third invention, each operation is performed by designating each video operation button with the pointing device. This enables a user interface that does not require command input.

According to the fourth aspect of the invention, in the video capturing / reading means, the video operating buttons for capturing the video in real time or searching and reading the image on the video storage medium are displayed on the video operating button display means. Therefore, using those video operation buttons, writing on the video storage medium,
And reading from the video storage medium. Therefore, the above problem can be solved.
