Abstract

An input display device includes a display unit that displays a screen for handwriting input on an input screen including a plurality of input fields, a stroke data processing unit that groups stroke data which is input to a capture screen by handwriting into stroke data representing characters to generate grouped stroke data as grouping stroke data, a character recognition unit that conducts character recognition on the grouping stroke data to convert the grouping stroke data into at least one recognized character, and a control processing unit that displays the at least one recognized character at the plurality of input fields of the input screen correlated with positions, at which handwriting input was performed, in the screen for handwriting input.

Claims

1. An input display device comprising:

a display unit configured to display a screen for handwriting input on an input screen including a plurality of input fields;

a stroke data processing unit configured to group stroke data which is input to the screen for handwriting input by handwriting into stroke data representing characters to generate grouped stroke data as grouping stroke data;

a character recognition unit configured to conduct character recognition on the grouping stroke data to convert the grouping stroke data into at least one recognized character; and

a control processing unit configured to display the at least one recognized character at the plurality of input fields of the input screen correlated with positions, at which handwriting input was performed, in the screen for handwriting input.

2. The input display device according to claim 1,

wherein the stroke data processing unit is configured to group the stroke data into the stroke data representing characters correlated with the plurality of input fields to generate grouped stroke data as grouping stroke data.

3. The input display device according to claim 1,

wherein the control processing unit is configured to display the at least one recognized character obtained by conducting character recognition on the grouping stroke data at the plurality of input fields based on a coordinate region of the grouping stroke data and a coordinate region of the input field.

4. The input display device according to claim 1,

wherein the character recognition unit is configured to

determine whether character recognition is to be conducted, based on a coordinate region of the grouping stroke data and a coordinate region of the input field, and

in a case where it is determined that character recognition is to be conducted, conduct character recognition on the grouping stroke data to convert the grouping stroke data into the at least one recognized character.

5. The input display device according to claim 1,

wherein attribute information is correlated with at least one input field of the plurality of input fields, and

the character recognition unit is configured to determine whether the character recognition is to be conducted based on the attribute information of the input field, and

in a case where it is determined that the character recognition is to be conducted on the input field, conduct character recognition on the grouping stroke data correlated with the input field to convert the grouping stroke data into the at least one recognized character.

6. The input display device according to claim 5,

wherein the attribute information includes restriction information due to a character type of an input field, restriction information due to an input method selected or designated by a user, and/or information which indicates a signature field to be input by handwriting.

7. The input display device according to claim 1,

wherein the stroke data processing unit is configured to generate stroke data which is not correlated with any of the plurality of input fields as handwritten characters, and

the control processing unit is configured to display the handwritten characters on the input screen.

8. The input display device according to claim 1,

wherein the screen for handwriting input is a capture screen, and

the control processing unit is configured to capture the input screen displayed on the display unit as the capture screen and display the capture screen on the input screen.

9. The input display device according to claim 1,

wherein a display form of the input field is at least any of frame display, underline display, and no frame display.

10. An input display method comprising:

displaying a screen for handwriting input on an input screen including a plurality of input fields;

grouping stroke data which is input to the screen for the handwriting input by handwriting into stroke data representing characters and generating grouped stroke data as grouping stroke data;

conducting character recognition on the grouping stroke data and converting the grouping stroke data into at least one recognized character; and

displaying the at least one recognized character at the plurality of input fields of the input screen correlated with positions, at which handwriting input was performed, in the screen for handwriting input.
