1 is a diagram illustrating a connection between a mobile communication terminal and a personal computer having an image recording apparatus to which the present invention is applied.

Referring to FIG. 1, the controller 10 controls the overall operation of the mobile communication terminal. The control unit 10 includes a ROM for storing a predetermined operation program and a RAM for storing temporary data generated during the execution of the program. The key input unit 20 includes a plurality of numeric keys and function keys, and outputs key data for the keys to the controller 10.

The display unit 30 receives and displays display data corresponding to the key data output from the key input unit 20 from the controller 10. In addition, the display unit 30 receives image data such as moving image and still image data from the control unit 10 and displays it, and displays various information such as weather and news.

The image file storage unit 40 stores image data such as an image file and a moving image file.

The camera unit 50 converts an image taken through a camera lens into a digital signal, and captures the continuous digital image as a still image to generate an image file or capture a continuous image for a predetermined time to generate a moving image file. Create and print

The compression controller 60 receives image data such as a predetermined image file or a moving image file provided from the camera unit 50 under the control of the controller 10, compresses the image data to the image file storage unit 40. Save it. The external interface 70 interfaces signals between external devices such as the personal computer 103 or the like. The external interface 70 may be a universal asynchronous receiver and a transmitter (UART) or a universal synchronous bus (USB). Here, the external interface 70 and the connection cable of the external device may use a serial transmission module RS232C.

FIG. 2 is a diagram illustrating a detailed view of a camera unit for generating an image file in FIG. 1, which will be described with reference to the drawing.

As shown in FIG. 2, the camera unit 50 of FIG. 1 receives an on-control signal from the controller 10 and outputs a digital image of the image taken through the lens as a digital signal, and from the controller 10. An image capture unit 53 which receives a predetermined capture control signal and captures and outputs the continuous input digital signal; and an image file generator which generates an image file captured by the image capture unit 53 as an image file ( 55).

In the mobile communication terminal having the configuration as described above, when a user wants to store an image or video and inputs a predetermined key of the key input unit 20, the control unit 10 receives the corresponding key data from the key input unit 20 to receive a camera. An on control signal is output to the unit 50 to drive the camera unit 50. When turned on, the camera unit 50 converts an image input through the lens into a digital signal and outputs the digital signal to the controller. The control unit 10 receives the digital signal and displays it on the display unit 30. At this time, when the user sees the display unit 30 and the desired image is displayed and inputs a predetermined key for capturing an image from the key input unit 20, the controller 10 receives key data corresponding to the key. An image capture signal is output to the screen capture unit 53 of FIG. 2 to capture and output an image displayed on the display unit 30 in size of 320 × 200 pixels × 8 bits. The image file generator 55 then converts the captured digital signal into an image file of 64 KBytes and outputs it to the compression controller 60. The compression controller 60 compresses the image file of 64 KBytes by a predetermined method and stores the image file in the image file storage 40 as an image file having a much smaller value. In this case, the size of 320 × 200 pixels × 8 bits is determined in consideration of the fact that the display unit 30 of the mobile communication terminal is not very large. The compression method includes RLE (Run Length Encoding) and the like. When compressed with the RLE, the compression method can store a value much smaller than 64 KBytes. Therefore, assuming that there are about 5 screens to be considered even without compression, only 500KBytes storage is required.

3 is a flowchart illustrating a method of storing image data in a mobile communication terminal having an image recording apparatus according to an embodiment of the present invention.

Referring to FIG. 3, first, the controller 10 checks whether a camera driving key for driving the camera unit 50 is input from the key input unit 20 in step 201. When the camera driving key is input in step 201, the controller 10 outputs and drives an on control signal to the camera unit 50 in step 202. The camera unit 50 may automatically turn on by inputting a call key of the key input unit 20 or detecting flip open when the camera has a flip. When the camera unit 50 is turned on and driven in step 202, the controller 10 receives image data from the camera unit 50 and displays the image data on the display unit 30. When the image captured by the camera unit 50 is displayed on the display unit 30, the controller 10 proceeds to step 205 and checks whether the image capture key is input from the key input unit 20. In this case, when the image capture key is input from the key input unit 20, the controller 10 outputs a capture control signal to the image capture unit 53 of the camera unit 50 in step 207 to instantaneously input digital image data. Capture and output image data. In this case, the captured image is an image displayed on the display unit 30 when the user inputs an image capture key. The image data is converted into an image file by the image file generator 55 and output to the compression controller 60. When the image file is output, the controller 10 controls the compression controller 60 to compress the image file and store it in the image file storage 40 in step 209.

The image file stored in FIG. 3 may be edited and stored in the computer 103. First, in order to edit an image file in the computer 103, the serial port of the computer 103 must be connected through the external interface 103 of the mobile communication terminal 100. When connected in this way, the image file stored in the image file storage unit 40 may be edited through the processes of FIGS. 4 and 5.

FIG. 4 is a flowchart showing a computer editing method for editing the image file stored in FIG. 2, and the operation of the computer 103 will first be described.

First, when the user inputs a program command for editing an image file, the computer 103 drives the corresponding application program in step 301. When the application program is started, the computer 103 checks whether an image file read command is input in step 303. In this case, when an image file read command is input, the computer 103 proceeds to step 305 to determine whether the mobile communication terminal 100 is connected. As a result, if the mobile communication terminal 100 is connected, the computer 103 transmits an image file read command to the controller 10 through the external interface 70 in step 307. After the image file read command is transmitted, the computer 103 proceeds to step 309 to check whether the compressed image file is received. When the compressed image file is received during the inspection, the computer 103 decompresses the compressed image file and displays it on the monitor. When the image file is displayed, the computer 103 performs editing by the user in step 313. When the editing is performed by the user, the computer 103 proceeds to step 315 to check whether a transmission command is input, and when the transmission command is input, to step 317. In step 317, the user is asked whether to store the data. If a storage command is input in response thereto, the image file is stored in a hard disk (not shown) in the computer 103. However, if a save command is not input, the computer 103 proceeds to step 319. In step 319, the computer 103 compresses the image file and transmits the image file to the mobile communication terminal 100.

FIG. 5 is a flowchart showing a method of transmitting image data to a computer according to FIG. 3, and illustrates the operation of the mobile communication terminal according to FIG.

First, the controller 10 of the mobile communication terminal 100 checks whether an external device is connected to the external interface 70 in step 401. If an external device is connected to the external interface unit 70, the controller 10 proceeds to step 403 to check whether the image file read signal is input from the external interface unit 70. In this case, when the image file read signal is input, the controller 10 proceeds to step 405 to read the image file from the image file storage unit 40, and reads the read image file through the external interface unit 70. To send. After the image file transfer, the controller 10 proceeds to step 407 and checks whether an image file is received from the computer 103. When the image file is received in step 407, the controller 10 stores the image file received through the external interface unit 70 in the image file storage unit 40 in step 409. At this time, the image file is a compressed image file.

As described above, the present invention has an advantage of increasing the user's satisfaction by storing an image (image) desired by the user as an image file and editing the image on a computer.
