Description

Digital video editing system and the operating method

The present invention relates to a digital image editing system and a method of operating a still image or moving image in a mobile communication terminal.

Recently, as the information society enters, the information communication method is gradually developed from the wire communication to the wireless communication method.

The wireless communication method is a mobile communication that can exchange information with a small, lightweight terminal that is easy to carry without being greatly restricted by time and space, and a satellite communication that can perform information transmission without borders between countries through satellites. It can be broadly classified as a mobile communication.

The mobile communication means to communicate wirelessly between a mobile station and a fixed point or between mobile stations. In general, the wireless communication service is preferred in the past voice call-oriented service in view of the technology development process of wireless communication for the mobile communication. The paradigm of service is changing with the emergence of video terminals rather than text-based terminals.

A mobile communication terminal that can implement the mobile communication technology will quickly change from a conventional voice center to a data center and further into a multimedia composite terminal.

This is because the data transmission speed is faster and cheaper data communication becomes possible as the mobile communication technology develops. Accordingly, it is expected that the Enhanced Messaging Service (EMS) and Multimedia Messaging Service (MMS) functions become important. MMS is a wireless Internet service that can send and receive not only text but also multimedia such as color pictures, animations, melodies and videos. EMS is also a transitional form of MMS.

At present, the mobile communication terminal has a basic form of 64,000 color LCD and 16/40 chord support, and multimedia supporting mobile terminals such as VOD support, GPS embedded, and video camera will form a significant market. It is expected.

As described above, the technological environment of the mobile communication terminal is rapidly changing, and in particular, it is expected to be an issue related to the image technology.

In the related art, the conventional mobile communication terminal can only record, play back, and transmit a still image, a video, and the like by using a camera.

Considering the fact that the main user of the mobile communication terminal is a young generation who values individuality and differentiation from others, it is natural that the mobile communication terminal requires various additional functions for video.

Therefore, the user's demand for various changes to the conventional simple image of the mobile communication terminal is gradually increasing.

The present invention provides a variety of digital effects for a still image, a video taken by a user using a camera used in conjunction with the mobile communication terminal, or an image stored in the mobile communication terminal or transmitted or received from a counterpart. It is an object of the present invention to provide a digital image editing system and a method of operating the same, which implement various digital image effects on the image of the mobile communication terminal by implementing a device capable of providing the internal image central processing unit of the mobile communication terminal.
