Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to an information processing apparatus such as a personal computer, a portable telephone, and a PDA, and a method of inputting a character code string in the information processing apparatus.

[0002]

2. Description of the Related Art In recent years, the use of information processing apparatuses such as personal computers, mobile phones, and PDAs has been increasing. When using such an information processing device,
In some cases, it is necessary to input a character string by operating a keyboard, buttons, or the like to perform a desired process. However, if you are unfamiliar with the keyboard and buttons, it takes time and effort to input all the character strings one by one using them.

Therefore, in place of such an input device,
For example, it is conceivable that a character string is encoded and printed as a mark such as a bar code, and the character string is input by reading the character string.

[0004]

By the way, as described above, in order to encode a character string as a mark such as a bar code and read the character string to substitute for input using a keyboard or a button, any character string can be used. Although it is necessary to encode the mark in advance, this is practically impossible.

An object of the present invention is to reduce input of a character string to an information processing apparatus by using both automatic input of a character string using a mark such as a bar code and manual input of a character string from a keyboard or the like. And

[0006]

According to the present invention, there is provided an information processing apparatus comprising: a character code string acquiring means for acquiring a character code string;
A character code string storage means for storing a character code string obtained from the character code string acquisition means, and a character string display for converting the character code string stored in the character code string storage means into a character font and displaying the characters as characters And character code string correcting means for correcting the character code string stored in the character code string storage means.

According to the invention, the character code string acquired by the character code string acquisition means is stored in the character code string storage means. Then, the character code string is converted into a character font and displayed as characters by the character string display means. The user of the information processing apparatus can correct the character code string stored in the character code string storage means by the character code string correction means while looking at the displayed character string.

On the other hand, according to the character string input method of the present invention, a step of reading an encoded character string, a step of extracting the read character string as a character code string, and storing the extracted character code string. And a step of changing the stored character code string.

According to the present invention, for example, a mark or the like obtained by encoding a part of a character string is prepared, read out and taken out as a character code string, so that the input of the first character string is performed in a line. Then, the remaining character string input (second
Is input by, for example, adding a character string using a keyboard or a button or correcting a part of the input character string using a keyboard or a button. As a result, the input of the character string to the information processing device is achieved.
