Abstract

PURPOSE:To quickly and easily grasp a document by displaying a key word contained in a document image on a display screen in an emphasized form and with distinction secured from the parts of other words. CONSTITUTION:A selection part 6 selects a character that is coincident with a registered key word stored in a registered key word memory 7 as a key word out of those characters read out of a document or a character string including plural characters arrayed continuously. A coordinate designation part 8 decides the coordinates showing the position of each selected key word in the document. The coordinate data are stored in a key word memory 9 together with the key word data. An emphasis display part 10 displays the part of each key word on the screen of a CRT display 11 in an emphasized form and with distinction secured from the parts of other words based on each key word stored in the memory 9 and their coordinate data. Thus the document is quickly and easily grasped.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a keyword highlighting display device that displays keywords in a document image in an emphasized manner on a display screen, distinguishing them from other word parts.

[Conventional technology]

Conventionally, when displaying a document image on a CRT display screen, keywords and other words have not been distinguished from each other.

[Problem to be solved by the invention]

-C, it is effective to use keywords to quickly and easily understand documents. For example, documents related to global environmental protection issues use keywords such as "radiation,""ozonelayer," and "global pollution," so using these keywords as clues can help you read them quickly. In addition, the main points can be understood deeply.Therefore, it has been strongly desired to display keywords in a document image in an emphasized manner, distinguishing them from other words.The problem of this invention is to: Keyword highlighting solves the problems of conventional technology and displays keywords in a document image in an emphasized manner, distinguishing them from other words on the display screen, making it easier to understand the document quickly. The goal is to provide equipment.

[Means to solve the problem] In order to solve this problem, the keyword highlighting device according to the present invention has the following features: a selection unit that selects as a keyword a character that matches the registered keyword from among each character read from the document or a character string in which a plurality of these characters are consecutively arranged; a coordinate specifying section that determines the coordinates representing the position of each of the selected keywords in the document; an emphasis display section that is displayed in an emphasized manner to distinguish it from the word part; Equipped with [Effect]

Among the characters read from the document or a string in which a plurality of these characters are consecutively arranged, those that match the registered keyword are selected as keywords by the selection section. Coordinates representing the position of each selected keyword in the document are determined by the coordinate specifying section. On a screen on which a document image is displayed, each keyword part is displayed in an emphasized form, distinguished from other word parts, by a highlighting section based on the coordinates related to the keyword.

【Example】

Embodiments of the keyword highlighting device according to the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of this embodiment. In FIG. 1, a document 1 is input as an image into an image scanner 2, and the image data is once stored in an image memory 3.
is stored in Based on this image data, the recognition unit 4 performs character reading, and the character data related to the reading is stored in the character memory 5 together with its coordinate data. The process up to this point is the same as conventional character reading. Next, 6 is a selection section, and 7 is a registered keyword memory. The selection unit 6 selects a keyword that matches the registered keyword stored in the registered keyword memory 7 among each character read from the document or a character string in which a plurality of these characters are consecutively arranged. selected as. Reference numeral 8 denotes a coordinate designation section that determines the coordinates representing the position of each selected keyword in the document. The coordinate data is stored in the keyword memory 9 together with the keyword data. Reference numeral 10 denotes a highlighting section which, based on the keyword data stored in the keyword memory 9 and the coordinate data of the keyword, highlights the portion of each keyword on the screen of the CRT display 11 on which the document image is displayed. Display it in an emphasized form, distinguishing it from the word part. I2 is a keyboard for operating the CRT display 11. In addition, as a format for emphasizing the keyword part, for example, the keyword part can be highlighted and displayed brighter, the font can be changed, or the keyword part can be displayed with a frame or an underline. Regarding the operation of the embodiment, the second flowchart is
This will be explained with reference to the figures. In FIG. 2, each character of document 1 (see FIG. 1, hereinafter) is read in step S1, and the character data is stored in character memory 5 in step s2. In step S3, a single character or character string that matches the registered KW (keyword) stored in the keyword memory 7 is selected as the KW. This selection is done by the selection section 6. In step S4, the coordinate specifying unit 8 obtains coordinate data for each selected KW. In the next step S5, the highlighting section 10 highlights the corresponding KW part in the document based on each KW and its coordinate data in a format such as highlighting, changing the font, or using a framed angle. Ru. Note that the above procedure from step S3 to step s5 is repeated for all KWs. Note that this rehearsing operation is not shown in the flowchart.

【Effect of the invention】

According to the present invention, there are the following advantages compared to the conventional technology. (1) On the screen where the content of the read document is displayed, each keyword part is displayed in an emphasized form, distinguishing it from other word parts, so using each highlighted keyword as a clue, Document comprehension becomes quick and easy. (2) Similarly, using each highlighted keyword as a clue, it becomes easy to search for a necessary location.
