As the technology for the additional functions of the mobile phone is developed, the mobile phone can download various contents through text messages, games, pictures and videos using the camera, and wireless Internet access using the SMS service. In other words, the cellular phone for making a telephone call is basically multimedia.

In particular, as digital cameras become popular, mobile phones equipped with cameras (camera phones) are also becoming more popular. A camera phone is a mobile phone that is equipped with a small digital camera to take a picture. Since the camera is mounted on the phone, users can always carry it around and take pictures freely without any technical skills. Due to such performance, the demand for camera phones is increasing even though they are relatively expensive than general mobile phones. Camera phones come in a variety of types and capabilities, from products that can only take photos to products that can take 30 minutes of video, products with 260,000 color LCD screens and digital zoom.

When the user shoots a video using a mobile communication terminal with a built-in camera, the video recorded according to a user's selection is stored in the terminal. However, the conventional mobile communication terminal equipped with a camera has a problem in that it does not support the user if the user wants to connect to the video stored in the memory. Therefore, a video that is divided and shot several times can only be stored as a separate file.

The present invention is to solve this problem, it is an object of the present invention to be able to shoot the connection to the already recorded video.

According to an aspect of the present invention, a mobile communication terminal according to an aspect of the present invention, when a specific video file is selected from a user among already recorded and stored videos when shooting using a built-in camera, the captured image is a predetermined position of the selected video. It is then recorded from and recorded as one video file and processed for storage. As a result, the newly captured video from the camera can be recorded following the previously recorded and stored video file.

The foregoing and further aspects of the present invention will become more apparent through the preferred embodiments described with reference to the accompanying drawings. Hereinafter, the present invention will be described in detail to enable those skilled in the art to easily understand and reproduce the present invention.

As shown in the drawing, the operation unit 110, a display unit 120 for displaying a menu and an operation state, a wireless communication unit 130 for extracting voice and data signals from a wireless signal transmitted and received through an antenna, and a wireless communication unit 130 A voice input / output circuit 140 for inputting and outputting a voice call signal from a microphone and a speaker, a communication processor 100a for controlling voice and data communication,

The camera unit 170 converts an optical signal input from the lens system into an electrical signal, and outputs a list of moving image files stored in the display unit 120 by selecting a connection photographing mode from the operation unit 110, and then operating the operation unit 110. A control unit 100b which receives one of the files from the plurality of files and acquires a position to record thereafter, and outputs a recording control signal; and a selected image stored in the memory 150 by processing an image signal output from the camera unit according to the recording control signal. And a signal processor 160 which subsequently records from the recording position of the moving image file.

The operation unit 110 and the display unit 120 which is a conventional liquid crystal display (LCD) may have a conventional well-known configuration. In addition, the wireless communication unit 130 is configured to include an antenna and RF circuit for communication with the base station. In the present specification, the wireless communication unit 130 is interpreted to include not only various versions of CDMA but also existing methods such as cellular, GSM, and W-CDMA, as well as mobile communication methods to be introduced in the future. The voice input / output circuit 140 processes a conversion of digital voice data into an analog voice signal or vice versa, and is a well-known configuration including an additional circuit such as an audio amplifying circuit or a filter.

The baseband circuit of the wireless communication unit 130 and most of the circuits of the phone control unit 100 are commercially provided as a single integrated circuit. This integrated circuit, commonly referred to as an MSM chip, includes dedicated hardware to process communications therein, a digital signal processor and a general purpose microprocessor. Logically, these include a communication processing unit 100a for controlling voice and data communication, and a control unit 100b for controlling the entire terminal system according to an operation signal or an operation state input from the operation unit 110.

The camera unit 170 converts the optical signal of the captured image input from the camera lens system into an analog electric signal. Such conversion is generally made of a CMOS imaging device or CCD imaging device, a known device that converts light into an electrical signal for each pixel and sequentially outputs it in synchronization with a clock. After converting the converted analog electric signal to digital, it is converted into a format suitable for the input of the signal processor 160, which will be described later, and output.

The signal processor 160 captures an image output from the camera unit 170 in units of frames and compresses the image in an MPEG method. Under the control of the controller 100b, the compressed image data is recorded from a specific position of the video file stored in the memory 150. That is, the signal processor 160 continuously records from the specific position of the video file previously stored in the memory 150, that is, the position specified by the control of the controller 100b to be described later.

In addition, the signal processor 160 decompresses the moving image stored in the memory 150 and preferably outputs the display unit 120 in a 16-bit RGB data format. The memory 150 is a memory for storing image data processed by the signal processor 160, and may be preferably a flash memory.

The controller 100b firstly selects a video file of the video files pre-stored in the memory 150 through the control unit 110 and connects to the video when the camera is photographed. Then the position to record is obtained. The position obtained here may be an end of file (EOF). The controller 100b outputs a control signal to the signal processor 160 to record a video photographed from the acquired position. After the shooting is completed, the control unit 100b receives file information (information including the file title) newly through the operation unit 110 and updates the file to store it in the memory 150.

Therefore, the mobile communication terminal according to the present invention can subsequently record a newly photographed video in a video file selected by a user among video files already taken and stored.
