Abstract

PURPOSE:To accumulate the image information received once without receiving it through a telephone line again by transferring and accumulating the image information accumulated at a first image memory to a second image memory by the instruction of a user. CONSTITUTION:The received image information is temporarily accumulated to the first image memory 21 and displayed at a displaying part 2. When a user instructs the accumulation from a key pad 3, the image information accumulated in the first image memory 21 is accumulated into the second image memory 22 by the control means of a microprocessor circuit 19. Out of the image information accumulated in the second image memory 22, the desired image information is selected and displayed. Thus, the image information received once can be accumulated to a terminal without receiving it through a telephone line again.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a Videotex terminal device that stores and displays image information transmitted in a Videotex system network in a memory.

Information that selects and transmits the various information accumulated in the files of the conventional technical information center according to the request from the terminal, processes it on the terminal and displays it on the display, stores the necessary image information in the image memory, and makes it searchable. A search system is proposed.

For example, as shown in FIG. 2, a request is sent from the keypad 3 of the terminal 1 to the captain information center 6 via the interface 15. Modem 12° line connection section 11. Transmitted via Videotex network 6 and information center 6
Then, according to this request, image information is searched from the image information file 7 and transmitted to the terminal 1.

In the terminal 1, image information is read into a video RAM 17 via a modem 15 and processed by a microprocessor circuit 19 using a microcomputer (CPU) and a display control unit 16, and further converted into an analog signal via a D/A converter 18. A display section 2 consisting of a cathode ray tube, etc.
I am trying to display it in Then, if the displayed image information is the necessary image information, press the keypad 3 of terminal 1.
The image information is requested again from the information center 6, and at the same time, the terminal 1 is instructed to store the retransmitted image information in the image memory 21.

Here, 4 is a telephone, 13 is a microprocessor circuit 1
RAM used as a work area necessary for 9 to control
14 is a program ROM.

Problems to be Solved by the Invention In the conventional image information search and storage method as described above, image information is searched once, and then the image information to be stored is again sent from the information center 6 via a telephone line. receive,
Since the images are stored in the image memory 21, there are problems in that it takes time to operate and also requires duplicate line usage fees.

In view of the above-mentioned problems, the present invention allows image information to be stored in an image memory without having to receive the image information once again from an information center via a telephone line, and is therefore economical. The purpose of the present invention is to provide a videotex terminal device that is easy to operate and has a low burden on users.

Means for Solving the Problems The Videotex terminal device of the present invention utilizes a first image memory that stores the latest received image information that is transmitted, and a second image memory that stores a plurality of pieces of image information. and a microprocessor circuit that controls the image information stored in the first image memory to be transferred to and stored in the second image memory in response to an instruction from a person.

According to the Videotex terminal device of the present invention, the latest received image information is stored in the first image memory, so in order to store the image information, the control means controls the first image memory. It is only necessary to store the image information stored in the first image memory in the second image memory, and there is no need to receive the image information again, so there is no need for duplicate line usage fees, and The above operation requires only one key operation and is easy to operate.

EXAMPLE An example of the present invention will be described below with reference to the drawings. FIG. 1 shows a block diagram of an embodiment of the present invention.

In FIG. 1, 21 is a first image memory that stores the latest received image information received from the information center 6, and 22 is a first image memory that stores the image information stored in the first image memory 21 according to a user's selection instruction. This is a second image memory for storing images. The configuration of other parts is the same as that in FIG. 2.

This terminal device 1 can basically perform the same operation as the one shown in FIG. In accordance with this request, the information center 6 searches for image information from the image information file and sends it to the terminal device 1.

The received image information is then temporarily stored in the first image memory 21 and displayed on the display section 2.

Thereafter, the user determines whether the image information should be stored in the terminal 1, and if so, instructs storage from the keypad 3. In response to instructions from the keypad 3, the control means of the microprocessor circuit 19 causes the image information stored in the first image memory 21 to be stored in the second image memory 22. Then, desired image information is selected from among the image information stored in the second image memory 22 and displayed.

According to this configuration, image information can be stored in the terminal 1 with a simple operation without having to receive image information once received again via a telephone line.

Effects of the Invention As described above, according to the present invention, image information once received can be stored in an image information storage memory with a simple operation without having to receive the image information again via a telephone line. It has the advantage of being easy to operate and very economical in terms of line usage charges.
