Hereinafter, the electronic organizer and electronic dictionary device of the next generation mobile communication terminal according to the present invention will be described in detail with reference to the accompanying drawings.

First, the general concept of the present invention will be briefly described before explaining the preferred embodiment of the present invention.

The present invention contemplates that a handwritten or typed character may be recognized as a still picture in a next generation mobile communication terminal equipped with a camera for a video call. That is, when talking to the other party, the camera mounted on the terminal performs a function of transmitting and receiving the caller as a real-time video, but when the camera does not perform a video call function, the camera switches to the electronic notebook mode by the user's operation. By capturing still images, the user's electronic organizer functions.

In addition, when the next-generation mobile communication terminal is switched to the electronic dictionary mode by processing the still image input by the user into the text data, by indexing the text data in the database stored in the flash memory of the terminal and output the result to the liquid crystal display, By simply capturing a word written on a paper in the camera of the terminal, the user provides the same function as referring to a dictionary.

1 is a block diagram showing the configuration of the electronic organizer and electronic dictionary device of the next-generation mobile communication terminal according to the present invention.

As shown, a first switch 11 and a second switch 12 for switching the terminal to an electronic notebook mode and an electronic dictionary mode according to a user input, and the first switch 11 and the second switch 12. A camera 10 receiving still image data from a user, an image processor 13 for processing still image data input from the camera, and still image data processed by the image processor 13; A flash memory 15 storing an electronic dedicated database, a mode depending on whether the first switch 11 and the second switch 12 are connected, and the image processing unit and the liquid crystal display unit 16; It consists of the MSM 14 which controls flash memory.

The first switch 11 and the second switch 12 are used to distinguish between the electronic notebook mode and the electronic dictionary mode of the next-generation mobile communication terminal, and the user switches the mode through the switch when the user wants to use each mode. Just do it.

Here, the first switch 11 and the second switch 11 may be operated only when the user uses each function in order to minimize the power consumption of the terminal.

When the first switch 11 and the second switch 12 are operated, the still image is recognized by a CPU (not shown) inside the MSM through a GPIO (General Purpose Input / Output) port of the MSM 14. It is notified that the mode for, i.e., the electronic notebook mode or the electronic dictionary mode is switched, and at the same time the image processor 13 is also activated (On).

For example, when the user of the terminal wants to store a paper recording important data by using the electronic organizer function of the terminal, the image processing unit 13 switches the terminal to the electronic organizer mode through the first switch 11. The camera 10 of the terminal is in a standby state for inputting a still picture.

When the user's paper is captured as a still image through a camera, the image processing unit processes the captured still image data, and the MSM 13 controls the image processing unit and the memory 15 to store in the memory. The captured still image is stored and the captured still image is output to the liquid crystal display 16 so that the user can check the still image to be input.

The stored still image data is output to the liquid crystal display according to a user's need to provide a function equivalent to indexing a notebook written by a user by hand.

Meanwhile, in order to implement an electronic dictionary function with the terminal, an electronic dictionary database must be stored in advance. In the present invention, the electronic dictionary database is stored using a flash memory inside the terminal.

In addition to the flash memory, the next-generation mobile communication terminal uses a static ramdom access memory (SRAM) and an electrically erasable programmable read-only memory (EEPROM), among which the flash memory 15 includes an operating system and other additional functions required for the operation of the terminal. Since the memory area for providing is used, the remaining area of the flash memory is used to store the electronic private database.

For example, when the user of the terminal attempts to index a word using the electronic dictionary of the terminal, the image processing unit 13 is operated when the terminal switches to the electronic dictionary mode through the second switch 11. The camera 10 enters a standby state for inputting a still image.

When the paper on which the word to be indexed is recorded is input to the camera as a still image, the image processor 13 processes the still image received from the camera into text data, and the MSM 14 stores the image in an internal register. The character data extracted from the processing unit 13 is temporarily stored.

The electronic data storage database stored in the flash memory 15 is indexed with character data temporarily stored in a register inside the MSM, and the index result is output to the liquid crystal display.

As a result, the user can use the electronic notebook function or the electronic dictionary function without inputting the text data to the terminal by simply inputting the paper containing the data as a still image on the terminal.

As described above, the electronic organizer and electronic dictionary device of the next-generation mobile communication terminal of the present invention have an effect of increasing the efficiency of terminal resource utilization by using the spare memory of the next-generation mobile communication terminal for the electronic dictionary database construction.

In addition, by expanding the use area of the camera used to transmit and receive video calls and videos of the terminal, the terminal simply captures the paper on which the data or image is recorded on the camera without the user having to input characters for data input. There is an effect that can be used as an electronic notebook or electronic dictionary.
