Abstract

PURPOSE:To attain the input operations of the handwritten characters or images into the same input area by deciding a mark to show the image input or the character recognition input that is previously defined and controlling the input of images or characters. CONSTITUTION:When the image data inputted in dots to a lower right corner 21 of an input area is fetched by an input memory 5, an input decision control part 6 checks the presence or absence of the dot input in the area 21. When the presence of the dot input is confirmed, an image input signal 11 is outputted to a recognition control part 8. The part 8 regards the data on a memory 5 as the image data and adds a control code to show that the subsequent data are equal to the image data. Then the image data are stored in a memory 7 and transferred to a display part 9. Then the part 6 performs the same working as before when the character input is fetched by the memory 5. Thus the part 6 outputs no signal 11 owing to the absence of the dot input. The part 8 detects the signal 11 and regards the data on the memory 5 as the character data to perform the recognition of characters and the conversion of character codes. Then the part 8 stores the character codes into the memory 7 and transfers them to the part 9.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a handwriting input device, and particularly to a handwriting input device that can input images such as special symbols and simple pictures in addition to inputting handwritten characters.

[Conventional technology]

Conventionally, as described in Japanese Patent Laid-Open No. 62-35988, for example, input information written within the frame of an input canister is determined to be a character, and input information that exceeds the frame is determined to be a figure, thereby converting it into a single figure. There was a technology that could read handwritten documents containing .

[Problem to be solved by the invention]

With the above conventional technology, it is possible to input handwritten characters or figures depending on how they are written inside and outside the frame, but it is necessary to input with the frame in mind, and input near the border of the frame is not possible. requires means and processing for determining whether character input or graphic input is input.゛An object of the present invention is to enable a handwriting input device to input characters or images in the same manual area with a simple operation, and to determine whether character input or image input is input using easier processing. An object of the present invention is to provide a handwriting input device that can perform handwriting input.

[Means to solve the problem]

The above object is to provide a handwriting input device with an input determination control section that has a function of determining whether image input or character recognition input is performed based on a predefined indicator indicating whether image input or character recognition input is to be input, Determine if it is a character recognition input, control the input as an image,
Alternatively, this can be achieved by recognizing characters and controlling character input.

[Effect]

In the handwriting input device, when an input operation is performed, the input determination control unit identifies a predefined indicator for distinguishing between image input and character input, and the input information is image input. When it is determined that this is the case, a signal indicating that the input is an image is output to the recognition control unit.

Thereby, the recognition control section regards the input data as image data, and can store it in the memory or display it on the display section as it is without character recognition.

[Example] An example of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a handwriting input device according to the present invention. In FIG. 1, a handwriting input device 1 includes a tablet 2,
An input pen 3 that inputs characters and the like into the tablet 2, an input control unit 4 that converts information from the tablet 2 into digital data, and an input memory 5 that stores input data.
, an input determination control unit 6 that detects whether there is an operation indicating a predefined image input and determines whether it is a character input or an image input, recognition of handwritten characters, character code conversion after recognition, and It is equipped with a recognition control section 8 and a display section 9 that store character codes and image data in a memory 7 and transfer them to a display section. Further, the input determination control section 6 determines whether the input is a character input or an image input, and outputs an image input signal 11 to the recognition control section 8 if the input is an image input.

Figure 2 shows tablet 2 when inputting text and inputting images.
It is a diagram showing the input state of the data of the input canilia above,
Here, the first two characters indicate character input, and the third input indicates image input.

FIG. 3 is a diagram showing the data displayed on the display unit 9 after input and the state of storage of the data in the memory 7.

Next, the operation of the handwriting input device 1 of this embodiment will be explained.

In this example, as an operation to indicate image input,
If you perform a dot operation on the lower right corner of the input data along with input data, that input data is defined as image input,
If a normal input operation is performed without performing this operation, the input data is defined as character input.For example, in FIG. 2, mail and mail are character input, and 〒 is image input.

In addition, the recognition control unit 8 converts character recognition input into the memory 7.
Regarding the data stored in , A1 to An are character codes, B1 to Bm are image data, and Co is a control code that defines that the subsequent data is image data. In the example of FIG. 3, m bytes of image data B1 to Bm follow Co.

When inputting an image to the handwriting input device 1, the input pen 3 is used to input image data into the input area on the tablet 2, and a dot is placed on the lower right corner 21 of the input area. When the input control section 4 takes input information into the input memory 5, the input judgment control section 6 inputs the input information into the input memory 5.
Check whether there is a point power in area 21 (area on the input memory corresponding to the lower right corner of the input canister).

If there is a point power, it is determined that the input data in the input memory 5 is image data, and an image input signal 11 is outputted to the recognition control section 8. The recognition control unit 8 detects that the image input signal 11 is being output.

It recognizes the data in the input memory 5 as image data, adds a control code Go indicating that the subsequent data is image data, and then stores the image data B1 to Bm in the memory 7 and directly displays them on the display section 9. Forward.

Next, when entering characters, input characters into the input pen 3 using the input pen 3. When the input control section 4 takes in the input information into the input memory 5, the input determination control section 6 checks whether there is a point strength in the area 21 in the input memory 5 in the same manner as in the above operation. In this case, since there is no power, the input determination control section 6 determines that the data is character data, and does not output the image input signal 11 to the recognition control section 8 . The recognition control unit 8 detects that the image input signal is not output, regards the data in the input memory 5 as character data, performs character recognition and character code conversion, stores the character code An in the memory 7, and displays it. Transfer to Department 9.

In the above embodiment, a point force to the lower right corner of the input canister was defined as an operation indicating image input.
It is clear that the position of the point force may be in another corner, and that the same implementation can be achieved by defining it by inputting an angle line or by enclosing the input canine area instead of the point force. In addition, it can be similarly implemented by defining that a predefined operation is to be performed only when inputting characters rather than when inputting images, and furthermore, it is defined that the operations defined in advance are to be performed both when inputting images and when inputting characters. It is clear that it can be implemented in the same way.

〔Effect of the invention〕

According to the present invention, in addition to inputting handwritten character recognition using a handwriting input device, image data such as special characters and simple pictures can be inputted with easy operations, thereby improving usability.
