Abstract

PURPOSE:To extract a data at any time as required and to generate a document such as an agenda automatically by providing a data compression/expansion section, a data storage section, a data edit section, a line control section and a printer control section or the like in the system. CONSTITUTION:At first a character and a graph described on a board 5 are extracted by a data scan section 6 as image data, which is sent to a data compression/expansion section 8 via a data bus 13. The data compressed therein is stored tentatively in a main storage section 3 via the data bus 13 and stored in a data storage section 9 finally. Then the data stored therein is expanded at the data compression/expansion section 8 this time via the data bus, the expanded data is edited into an agenda or the like by a data edit section 10 and stored in the main storage section 3. The stored data is printed out via a printer control section 12 on a print request. Moreover, a data is sent to a request destination via a public line network from a line control section 11 in response to the data request from a remote location.

Description

[Detailed description of the invention] [Industrial application fields] The present invention relates to an electronic whiteboard.

[Conventional technology] Conventional electronic blackboards change the page content written on the board.

It only had the function of copying and copying its contents.

[Problems to be Solved by the Invention] The conventional electronic blackboard described above only had the functions of page breaks and copying, so it was impossible to see the erased content again, and only the content written on the board could be copied. could not.

[Means for Solving the Problems] The present invention provides an electronic blackboard having a function of copying the contents written on the board by data scanning, in which data from a data scanning unit can be compressed/expanded through a data bus. a data compression/decompression unit; a data storage unit that can store and store compressed data; and a data editing unit that can retrieve the stored data at any time and edit it into a predetermined document via the data bus and main storage unit. , a line control unit that can transmit data in response to requests from a remote location, a printer control unit that can output printer output in response to print requests, and a data bus that transmits and receives data and control signals between these functional blocks. It is characterized by this.

[Example code] Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a functional block diagram of an embodiment of the present invention. This electronic blackboard includes five new functional blocks and a data bus in addition to the functional blocks of the conventional electronic whiteboard (the area surrounded by the dashed line).

First, characters and figures written on the board 5 are collected as image data by a data scanning section 6 and sent to a data compression/expansion section 8 via a data bus 13. The compressed data is temporarily stored in the main storage section 3 via the data bus 13, and finally stored and saved in the data storage section 9.

Next, the data stored here is decompressed by the data compression/decompression section 8 via the data bus, and then decompressed by the data editing section 10.
The minutes are edited into minutes and stored in the main storage unit 3. Printer output can be performed via the printer control unit 12 in response to a printer request.

In addition, in response to data requests from remote locations, the line control unit 1
Data can be transmitted from 1 to the request destination via the public line network.

[Effects of the Invention] As explained above, the present invention includes a data compression/expansion section, a data storage section, a data editing section, and a single line control section.

By providing a function such as a printer control unit, data can be retrieved whenever necessary, and an editing function allows automatic creation of minutes, etc. Further, according to the present invention, data can be accessed at any time from a remote location, and data can also be transmitted to a remote location, so it can be expected to be used for electronic whiteboard applications such as video conferences.
