Abstract

An electronic dictionary apparatus which is capable of actively supporting the thinking of the user during its use, and which has the improved maneuverability and the wider utility. In the apparatus, each letter pattern series in the entered input document is automatically extracted and recognized in order to obtain a corresponding letter code series; then the entered input document superposed with an enclosure image enclosing each letter pattern series for each of the extracted and recognized letter pattern series is displayed; then a user specifies a desired one of the displayed letter pattern series enclosed by the enclosure image; and then information on the letter code series corresponding to the specified letter pattern series is looked up in the data-base containing prepared information on a number of letter patterns in terms of letter codes.

Claims

1. An electronic dictionary apparatus, comprising:

image input means for entering an input document image representing an image of an input document and containing a number of letter pattern series formed by series of letter patterns;

recognition means for extracting and recognizing each letter pattern series in the input document image entered by the image input means in order to obtain corresponding letter code series, in response to an entering of the input document image by the image input means;

display means for displaying the input document image entered by the image input means with a superimposition of an enclosure image enclosing each letter pattern series extracted and recognized by the recognition means;

user operation means for allowing a user to specify one of the letter pattern series which is displayed on the display means as being enclosed by the enclosure image superimposed onto the input document image displayed on the displaying means by pointing to the enclosure image enclosing said one of the letter pattern series; and

look up means for looking up information on the letter code series obtained by the recognition means which corresponds to the letter pattern series specified by the user by using the user operation means in a data-base storing information on a number of letter patterns in terms of letter codes.

2. The apparatus of claim 1, wherein the recognition means recognizes hyphenated words, and the display means superimposes a single enclosure image around each of the hyphenated words recognized by the hyphen recognition means.

3. The apparatus of claim 1, wherein the recognition means recognizes groups of words, and the display means superimposes a single enclosure image around each of the groups of words recognized by the recognition means.

4. The apparatus of claim 1, wherein in extracting and recognizing each letter pattern series on a particular letter line, the recognition means utilizes information on subsequent letter lines in order to extract and recognize a complete letter pattern series presented over more than one letter lines.

5. A method of dictionary looking up in an electronic dictionary system, comprising the steps of:

entering an input document image representing an image of an input document and containing a number of letter pattern series formed by series of letter patterns from an image input means of the electronic dictionary system;

extracting and recognizing each letter pattern series in the input document image entered at the entering step in order to obtain a corresponding letter code series, in response to an entering of the input document image at the entering step by a processing means of the electronic dictionary system;

displaying the input document image entered at the entering step with a superimposition of an enclosure image enclosing each letter pattern series extracted and recognized at the extracting and recognizing step, on a display means of the electronic dictionary system;

specifying one of the letter pattern series which is displayed at the displaying step as being enclosed by the enclosure image superimposed onto the input document image displayed on the displaying means by pointing to the enclosure image enclosing said one of the letter pattern series, by using a pointing means of the electronic dictionary system; and

looking up information on the letter code series obtained at the extracting and recognizing step which is corresponding to the letter pattern series specified at the specifying step in a data-base of the electronic dictionary system storing information on a number of letter patterns in terms of letter codes.

6. The method of claim 5, wherein at the extracting and recognizing step hyphenate words are recognized, and at the displaying step a single enclosure image is superimposed around each of the hyphenate words recognized at the automatically extracting and recognizing step.

7. The method of claim 5, wherein at the extracting and recognizing step groups of words are recognized, and at the displaying step a single enclosure image is superimposed around each of the groups of words recognized at the automatically extracting and recognizing step.

8. The method of claim 5, wherein at the extracting and recognizing step, in extracting and recognizing the letter pattern series on a particular letter line, information on subsequent letter lines are utilized in order to extract and recognize a complete letter pattern series presented over more than one letter lines.
