Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image display device that displays moving images and still images in a superimposed manner.

[Conventional technology]

Conventionally, as this type of image display device, there has been one shown in FIG. In the figure, 1 is a general television broadcasting, VTR, VDP, etc.f7) NTSC system RF modulation video signal source (hereinafter abbreviated as RF video signal source), 2 is an auxiliary storage device such as a magnetic disk, etc.・Following certain rules such as protocols and syntax,
Encoded still image data is stored. 3 is a personal computer that searches still image data stored in the auxiliary storage device 2 and sends it to a decoder to be described later; 4 is a personal computer that sends still image data search information to the personal computer 3;
a keyboard 5 for inputting data into the computer; 5 has a frame memory, decodes and stores still image data received from the personal computer 3, and reads it out for display; 1 a decoder such as a captain user terminal;
6 has an antenna terminal and a so-called 21-pin multi-connector, and is a television receiver (hereinafter referred to as TV) that displays a moving image supplied from the RF video signal source 1 and a still image supplied from the decoder 5 in a superimposed manner. (omitted).

Next, the operation will be explained. The still image data stored in the auxiliary storage device 2 is given a unique screen number and management information such as branch information for each screen, and the respective screens are connected in a tree shape. On the other hand, the keyboard 4 is configured, for example, as shown in FIG. It is done by doing something.

For example, as shown in FIG. 5, below the first screen O is screen 1. and screen 2 are connected, and as the branch information of screen O, if "1" is input from the keyboard 4, screen 1 will be displayed, and if "2" is input, screen 2 will be displayed. If information is attached, screen 1 or 2 screen 2 is displayed depending on the key input when screen O is displayed.

The personal computer 3 searches the auxiliary storage device 2 for corresponding still image data according to the screen number or branch information input from the keyboard 4 and transmits it to the decoder 5. The still image data decoded by this decoder 5 is
After being temporarily recorded in the frame memory in the decoder 5, it is D/A converted into an analog RGB signal and supplied to the TV 6 through a 21-bin multi-connect.

On the other hand, a moving image is first displayed on the TV 6 by the RF video signal supplied from the RF video signal a1, and at the same time, a demodulated video signal is input to the decoder 5 through the 21-bin multi-connector. The decoder 5 extracts a synchronization signal from this video signal, and reads the still image data stored in the frame memory in accordance with this timing.

That is, the moving image supplied from the RF video signal source 1 and the still image supplied from the decoder 5 are thereby completely synchronized. Furthermore, the decoder 5 sends a switching signal (so-called Ys multiplied signal) for switching and displaying moving images and still images pixel by pixel to the TV 6 through the 2.1-pin multi-connector at the same time as the color signal. You can obtain a screen display with a still image superimposed on it.

The above-mentioned superimposed display method is commonly used in so-called teletext broadcasting adapters.

In addition, in the above-mentioned superimposed screen, for example, information on whether or not the screen is to be superimposed is included in the still image management information, and in the case of VDP, address information on the disc on which the desired moving image is recorded. In addition, the personal computer 3 generally synchronizes the screen contents of moving images and still images each time the VDP is remotely operated.

[Problem that the invention seeks to solve]

Conventional image display devices are configured as described above, and only have the function of superimposing a still screen and a moving image. When the user performs the following, there are inconveniences such as the user having to take notes while looking at the display screen.

This invention was made to solve the above-mentioned problems, and provides an image display device that allows the user to make separate copies of moving images and still images that are displayed in a superimposed manner. The purpose is to obtain.

[Means for solving problems]

The image display device according to the present invention includes a printing means that inputs still image data and a moving image signal, and prints by switching between the two inputs based on a switching signal, and a selection that selects whether to print a still image or a moving image. The apparatus includes an operating means and a switching control means for outputting a corresponding switching signal to the printing means based on the operation of the selection operating means.

[Effect]

In this invention, when the user operates the selection operation means to select either still image printing or moving image printing, the switching control means outputs a switching signal corresponding to the above operation to the printing means, Still images or moving images are selectively printed by the printing means.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure, 1 indicates general television broadcasting, VTR, V
An RF video signal source such as DP, 2 is an auxiliary storage device such as a magnetic disk, and still image data encoded according to a certain rule such as Captain Protocol syntax is stored here. 3 is a personal computer that searches still image data stored in the auxiliary storage device 2 and sends it to a decoder to be described later; 4 inputs still image data search information and printing selection information to the personal computer 3; This keyboard corresponds to the selection operation means of the present application.

Reference numeral 5 has a frame memory, which decodes and stores still image data received from the personal computer 3 and reads it for display.

For example, a decoder 6 such as a captain user terminal has an antenna terminal and a so-called 21-bin multi-connector, and can receive a moving image supplied from the RF video signal source 1 and a still image supplied from the decoder 5. The TV for superimposed display, 7, has a multi-gradation video input terminal and a binarized digital data input terminal (lift), and a monochrome one that can be remotely controlled by a switching signal input from the outside to determine which one to print. It is a printing device and corresponds to the printing means of the present application.
The personal computer 3 and decoder 5 implement the switching control means of the present application in addition to the respective functions described above.

Next, the operation will be explained. The still image data structure stored in the auxiliary storage device 2 and the screen search method from the keyboard 4 are completely the same as in the conventional example. However, the keyboard 4 is, for example, as shown in FIG. 2(a).

(The personal computer 3 is configured as shown in bl, and in addition to the keys of the conventional example, print keys 4a and 4b for moving images and still images are provided.The personal computer 3 is configured as shown in FIG. , or according to the branch information, the corresponding still image data is searched from the auxiliary storage device 2 and sent to the decoder 5. However, when a moving image or still image printing key code is received, the still image data search is not performed. Instead, the corresponding control codes are sent to the decoder 5.The decoder 5, which has received these codes,
After switching the switching signal to the printing device 7 corresponding to a moving image or a still image, a printing start signal is transmitted to the printing device 7. At this time, the video input terminal of the printing device 7 is connected to the R
A video signal obtained by demodulating the RF video signal from the F video signal source 1 inside the TV 6 is input, and a still image data obtained by converting the still image data into a binary signal in the decoder 5 is input to the binarized digital data input terminal. Black and white data is input, and one of the above is selected and printed based on the switching signal.

Note that the still image and video superimposed display method or the decoder 5
The remote control method for the RF video signal source such as VDP in the present invention is completely the same as in the conventional example.

By the way, in the above embodiment, an RF modulated video signal source is used as the video signal source input to the TV 6. The superimposed display of moving images and still images was realized using a so-called teletext adapter system, but the configuration was such that a normal video signal that was not RF modulated was input to the TV 6, and the video output of the TV 6 was input to the decoder 5. However, the same effect can be achieved.

In addition, although the system was configured with a black and white printing device in the above example, it also accepts a color video signal and R, G, B as input.
Exactly the same effect can be expected even with a color printing device that has two inputs of n bits each (n: integer) and can switch inputs using an external signal.

〔Effect of the invention〕

As described above, according to the present invention, there is a printing means that inputs still image data and a moving image signal, switches between the two inputs based on a switching signal, and prints, and selects whether to print a still image or a moving image. By including a selection operation means for selecting the display screen, and a switching control means for outputting a corresponding switching signal to the printing means based on the operation of the selection operation means, the user does not have to take notes of information on the display screen. At the same time, a demonstration effect of the device can be obtained.
