Hereinafter, a mobile communication terminal 200 and an editing method according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1A is a diagram illustrating a configuration of a mobile communication terminal 200 and a PC 400 and a program providing server 100 for providing a program for performing an extension function according to an exemplary embodiment of the present invention. Referring to FIG. 1A, a mobile communication terminal 200 of the present invention is connected to a program providing server 100 through a wireless Internet network, and stores a program for performing an editing function according to a communication standard such as RS-232C. 400 is connected. In addition, an external expansion memory 300 storing a program for performing an extended editing function is connected to the mobile communication terminal 200. In the present invention, the external expansion memory 300 is preferably implemented in the form of a memory stick, but is not limited thereto. The mobile communication terminal 200 is a concept including both a mobile phone and a PDA capable of wireless Internet access.

FIG. 1B is a diagram illustrating a method in which the mobile communication terminal 200 and the external expansion memory 300 are connected. As shown in FIG. 1B, the mobile communication terminal 200 includes an insertion groove for inserting the removable temporary storage unit 282 of the memory 300, and the external expansion memory 300 is inserted into the insertion groove and moved. By connecting to the internal memory 280 of the communication terminal 200, the mobile communication terminal 200 provides an extended editing function of an image.

2 is a block diagram illustrating the configuration of a mobile communication terminal 200 and an external expansion memory 300 according to a preferred embodiment of the present invention. Referring to FIG. 2, the mobile communication terminal 200 includes a microphone 230, a speaker 232, a voice signal processor 234, an RF transceiver 220, a controller 250, for performing a function of a general telephone. And a key input unit 240, an image output unit (LDC panel 242), and an internal memory 280.

First, the RF transceiver 220 refers to a comprehensive configuration including a high frequency processor, an intermediate frequency processor, and a baseband processor. The RF transceiver 220 primarily processes a radio communication band frequency and lowers it back to a low frequency band. Then, it is lowered back to a frequency band processable by the controller 250 to generate a bit string. In addition, the RF transceiver 220 may be classified into a receiver and a transmitter, which are not shown, and the receiver of the RF transceiver 220 suppresses amplification of noise as much as possible, amplifies a desired signal, and generates a digital signal through an intermediate frequency. The digital signal is output to the controller 250, analyzed and processed. In addition, the transmitter of the RF transceiver 220 amplifies the signal generated by the controller 250 to a desired frequency band and amplifies it, and finally radiates through an antenna through a duplexer (not shown).

The internal memory 280 includes a temporary storage unit 282, a memory interface unit 284, and a first storage unit 286. The first storage unit 286 includes control data necessary for controlling the control unit 250. And a non-volatile memory (NVM: Non-Volatile Memory, for example, EEPROM, etc.) for storing a program for performing a basic editing function, and image data and various telephone numbers. The temporary storage unit 282 is embodied as a RAM that temporarily stores and processes data generated during the program control and a program that provides an editing function read from the external expansion memory 300.

The memory interface unit 284 reads a program for distinguishing the type of the external expansion memory 300 and performs a function of editing a moving image / still image stored in the external expansion memory 300 and writing the result to the temporary storage unit 282. do.

The controller 250 controls the overall operation of the mobile communication terminal 200, and controls the overall operation and external expansion memory 300 according to the video / still image editing when capturing the image according to the present invention.

The key input unit 240 has a key matrix structure (not shown), includes a character key, a numeric key, and various function keys, and generates and outputs a key input signal corresponding to a key input by the user to the controller 250. The key input unit 240 installs a shutter at a predetermined position of the exterior of the camera phone, generates a shutter input signal input according to the pressing of the shutter, and operates the camera, and also has a camera operation on / off key. Doing.

The voice processor demodulates the encoded voice signal received from the RF transceiver 220 and outputs the result to the speaker 232, and encodes a signal converted into an electrical voice signal by the microphone 230 to the RF transceiver 220. And outputs a voice signal to the synchronization unit 270 during video shooting and editing.

Meanwhile, the mobile communication terminal 200 of the present invention includes a photographing unit 210 and an image signal processing unit 212 so as to capture and store an image, and compresses and stores the captured still image and stores the stored still image. And a still image signal processing unit 260 for decoding and outputting the video, and a video signal processing unit 272 for compressing and storing the captured video and decoding the stored video. At this time, the photographing unit 210 is preferably composed of a lens and a solid-state imaging device (CCD).

In addition, in the case of including the audio signal in the video, it further includes a synchronization unit 270 for synchronizing the audio signal with the video signal.

3A and 3B are flowcharts illustrating an image editing process performed in the mobile communication terminal 200. First, FIG. 3A is a flowchart illustrating a process of editing a photographed image using a camera attached to the mobile communication terminal 200.

Referring to FIG. 3A, the photographing unit 210 outputs an analog image signal photographing an object to the image signal processor 212 according to a user's key input value (S302), and the image signal processor 212 outputs the analog image signal. The digital signal is converted into a digital image signal and output to the control unit 250 (S304). In this case, the photographing unit 210 may generate an analog video signal for one still image according to a user's setting, and output the analog video signal to the video signal processing unit 212, and generate an analog video signal composed of a series of video images. The signal may be output to the signal processor 212.

The controller 250 checks whether the digital image signal input from the image signal processor 212 is a moving image and outputs it to the still image signal processor 260 when the image is a still image (S306), and the still image signal processor 260. Compresses and encodes the input digital still image signal using a predetermined algorithm and outputs it to the internal memory 280 (S308). The first storage unit 286 of the internal memory 280 stores the input still image signal. do. In this case, the algorithm used for compression is preferably in accordance with the standard for the compression of still images such as JPEG, and the first storage 286 is preferably implemented as a nonvolatile memory (eg, EEPROM, etc.).

Meanwhile, when the digital video signal input from the video signal processor 212 is a video, the controller 250 checks whether or not the voice signals are input together from the audio signal processor 234. Together with the synchronization unit 270, otherwise outputs directly to the video signal processor 272 (S310). For example, when an analog audio signal input through the microphone 230 is converted into a digital signal by the voice signal processor and input to the controller 250 together with the video signal, the controller 250 is connected to the input voice signal. The video signal is output to the synchronizer 270 together.

The synchronizing unit 270 synchronizes the input video signal and the audio signal according to an internal clock and outputs it to the video signal processing unit 212 (S312). The video signal processing unit 212 similarly outputs the synchronized video signal and the audio signal. The compression is performed using the algorithm of the output to the internal memory 280 (S314).

However, if only a video signal is input from the video signal processor 212, and there is no signal input from the audio signal processor 234, the controller 250 outputs the input video signal to the video signal processor 212 (S310). The video signal processing unit compresses and encodes the video signal using the predetermined algorithm and outputs it to the internal memory 280 (S314).

In this case, the video compression algorithm preferably conforms to international standards such as MPEG.

Meanwhile, the internal memory 280 stores the input still image signal or a moving image signal in the first storage unit 286, and the stored images are edited according to an image editing method described later (S400).

3B is a flowchart for explaining a method of editing an image downloaded through a wireless Internet network. Referring to FIG. 3B, the RF transceiver 220 demodulates the still image signal or the video signal received through the wireless Internet network and outputs the demodulated image signal to the controller 250 (S320).

The control unit 250 checks whether the input video signal is compressed and coded (S322), and if it is compressed and coded, outputs it directly to the internal memory 280 and stores it (S326). However, if the compression is not encoded, it is checked whether the input signal is a moving picture or a still picture, and if it is a still picture, it is output to the still picture signal processing unit 260. After outputting the compressed and encoded data (S324), the data is output to the internal memory 280 and stored (S326). In this case, when the input video signal includes the audio signal, it is assumed that the audio signal is synchronized with the video signal.

Thereafter, the user may edit the stored video according to the video editing method described later (S400).

On the other hand, the process of receiving the image through the PC 400 connected to the mobile communication terminal 200 to perform the image editing of the present invention is similar to Figure 3b. However, there is a difference in that an image signal is received through the external interface unit 290 according to RS-232C, and a demodulation process such as step S320 described above is not necessary.

4 is a flowchart for describing operation S400, which is an image editing method illustrated in FIGS. 3A and 3B, in detail.

When a user wants to edit a stored image using the mobile communication terminal 200 of the present invention, the user selects an image to be edited through a key input unit and selects an image editing mode (S402).

When the image editing mode is selected, the controller 250 determines whether the external expansion memory 300 is connected, and if not, the editing function provided by the programs stored in the first storage unit 286 of the internal memory 280. And a list are displayed and displayed to the user as shown in FIG. 5A, and if the external expansion memory 300 is connected, the program is stored in the first storage unit 286 of the internal memory 280, The editing function provided by the programs stored in the second storage unit 302 of the expansion memory 300 is examined, a list is created, and output to the user as shown in FIG. 5A (S404).

The controller 250 receives user selection information regarding an image editing function through a key input unit (S406), and examines whether a program corresponding to the selected editing function is stored in the external expansion memory 300 (S408), If so, the corresponding program is read from the second storage unit 302 of the external expansion memory 300 to the temporary storage unit 282 of the internal memory 280 (S410).

The controller 250 executes a corresponding program to perform the selected editing function (S412), and edits the editing target image according to a user's key input value (S414).

 The edited image may be stored under a different name according to a user's selection, or may be changed and stored in operation S416. In this case, the edited image may not only be stored in the internal memory 280, but also may be transmitted and stored to a predetermined server on the web through the wireless Internet network through the RF transceiver 220, and the external interface unit 290 may be stored. It can be transmitted and stored in the PC 400 connected to the mobile communication terminal 200 through.

The description of the generally known functions among the basic image editing functions provided in the present invention will be omitted, and only the editing functions unique to the present invention will be briefly described. The image is rotated by a predetermined angle with respect to the center, or the symmetric pixel values of the top, bottom, left and right images of the image are interchanged with respect to the horizontal or vertical center axis of the LCD panel.

In addition, the color adjustment of the image function removes any one or two signals of the R, G, and B signals representing the image, or increases and outputs only one signal value at a predetermined ratio.

In addition, the decorating function of the layer function is a function of displaying a previously stored video over an edit target video and displaying a video showing a constant pattern on the outside of the video on the editing target video.

5B is a diagram illustrating a case where a user selects a mosaic function of a noise function among extended editing functions. In addition, images edited using Artistic, Distort, and Blur functions for the same image are illustrated in FIGS. 5C to 5E, respectively.

Hereinafter, a process of adding an editing function will be described with reference to FIG. 6, which describes a process of adding an external extended editing function.

According to the present invention, a program providing an extended editing function can be downloaded through the program providing server 100 or an external PC 400 as necessary, and the existing program can be deleted. As shown in FIG. 5B, the user may select a function addition in the extended editing function, and when the function addition item is selected, the controller 250 outputs a message asking the user how to add the function. In operation S600, selection information is input.

Access to (S604), and requests a list of programs that provide an extension stored in the server (S606).

If the selection information does not indicate downloading via the wireless Internet, the mobile communication terminal 200 is scheduled to download a program from the connected PC 400 according to the RS-232C method, and stored in the connected PC 400. The program list providing the extension function is requested (S606).

The controller 250 filters the program list provided from the program providing server 100 or the PC 400 and outputs the filtered list to the user (S608). Specifically, the controller 250 reads the program list and the remaining storage space information from the external expansion memory 300 to provide the extended editing function already stored in the external expansion memory 300, the program providing server 100 or Of the program list transmitted from the PC 400, the one already stored in the external expansion memory 300 and the program whose size exceeds the remaining storage space of the expansion memory are deleted from the list and displayed to the user.

The controller 250 receives the user's selection information through the key input unit (S610), requests the program providing server 100 or the PC 400 to download the program corresponding to the selection information, and the RF transceiver 220 Alternatively, the program received through the external interface unit 290 is output to the second storage unit 302 of the external expansion memory 300 and stored (S612).
