(Embodiment 4) Embodiment 4 of the present invention will be described. The fourth embodiment is the character recognition device according to the first, second, or third embodiment. One of the important functions in character recognition is a character extraction function. Hereinafter, the character recognition device will be described with reference to FIGS.
I will explain using. Reference numeral 901 denotes a character width estimating unit for estimating the character width of a character to be recognized; 902, an area dividing unit for detecting a break in a character image and dividing an image area for each break;
Reference numeral 3 denotes a character cutout unit that integrates the divided image regions as necessary and cuts them out as a character image, 904 denotes a character recognition unit, 905 denotes a character cutout, and calculates the estimated character width based on the result of character recognition. A character width updating apparatus 906 to 908 for updating is a part for making a cut-out determination when integrating the divided image areas into character units.
Is a character cutout score calculation device, 907 is a character cutout score memory, and 908 is a maximum cutout score position search device.

First, the length of the short side of the character line area to be recognized by the character width estimating unit 901 (W in FIG. 10).
c ′) is set as the initial character width, and the area dividing unit 902 obtains a peripheral distribution in a direction perpendicular to the line direction, and sequentially divides the area if there is a part where the peripheral distribution is larger than a certain threshold (for example, 0). If the width of each of the areas divided at the same time is similar to the initial character width, the attribute “CHAR” is attached, and if not, the attribute “SUBCHAR” is attached. Here, whether or not the character width and the width of the area are similar is determined by determining that the ratio of the absolute value of the difference between the character width and the width of the area to the character width is a fixed value (for example, 0.
2) If it is below, it is regarded as similar to character width. Here, it is assumed that the divided area with the attribute “CHAR” is estimated to be a character, and the divided area with “SUBCHAR” is estimated to be a part of the original character.

Next, the character extracting section 903 sequentially looks at the areas divided by the area dividing section 902, and finds that the attribute is "CHAR" (for example, the area r0 in FIG. 10).
If so, the character recognition unit 904 performs character recognition, and the character width updating unit 905 updates the character width. On the other hand, if the attribute of the area is “SUBCHAR” (for example, the area ri in FIG. 10), a cutout score is calculated for the area by the character cutout score calculation device 906 and stored in the character cutout score memory 907. Here, the method of calculating the character segmentation score is represented by the following equation (Equation 2) from the area width χ, the scores S1 and S2 of the first and second candidates of the character recognition result of the area, and the character width _Wci-1. Required by The meaning of this expression is such that the greater the value of (S1−S2), the higher the reliability of the first candidate, and the coefficient applied to the value increases as the character width approaches the character width.

Subsequently, the character cutout unit 903 looks at the attribute of the next area and determines whether the area is “CHAR” or the width of the area after integration becomes larger than α times the character width (for example, 1.2). And calculate the character segmentation score. Then, when the attribute of the area becomes “CHAR” or becomes larger than α times the character width, the maximum cut score position search device 908 obtains the position where the cut score becomes the maximum, and determines the integrated area at this position as a character area. At the same time, the character width is updated by the character width updating device 905. At this time, the maximum clipping score position search device 908 returns the position of the area next to the clipped area to the character clipping unit 903. The above operation is continued until there is no area to be cut out.

In updating the character width, a set average of estimated character widths when each area is integrated and re-divided as a character area by the above procedure is selected as a new character width.

(Embodiment 5) Embodiment 5 of the present invention will be described. The fifth embodiment is an information terminal having a post-processing function of a network address as a result of character recognition transmitted from a remote controller.

In the information terminal and the remote controller having the configuration shown in the second embodiment, after the characters are cut out and recognized by the method shown in the fourth embodiment, the network address is received by the infrared receiver 202 and the address search device 702 Passed to. Next, the address search device 70
2 is "http" in the Internet address.
p "," ftp "," WWW "or other scheme name," c
o ”,“ jp ”, etc.,“ html ”,“ v ”
rml "and other message / language type names,“: ”,“. ”,“ / ”,“

[0051] A grammar of address designation using these key characters prepared in advance is extracted as a key character to extract a delimiter such as "" as a key character (see FIG. 11).
Modify key characters while referring to. For example, FIG.
If the key character "." Is not included in the part that matches <Name>, it is a <Terminal>, that is, a proper noun, indicating that it cannot be further modified. With respect to proper nouns, a similar address can be searched for by leaving a part having a high recognition score as it is, expressing the rest as a regular expression, and querying an address database on a network. Post-processing and correction of the network address recognized by the above method can improve recognition accuracy.

[0052]
