More particularly, the present invention relates to an image editing method for generating a previously stored still image, a moving picture, a music file, etc. into a single moving image file, and a photographing apparatus using the same.

The photographing apparatus refers to a device for recording and reproducing an image signal generated by capturing a subject, and an audio signal on a recording medium through predetermined signal processing. The photographing apparatus can use a magnetic tape as a recording medium, and can record not only still images but also movies for a long time.

In recent years, not only magnetic tape but also HDD (Hard Disk Drive), memory card, memory stick, DVD (Digital Vedio Disc), BD (Blu-ray Disc), etc. can be used as a recording medium. In general, examples of the recording apparatus include a camcorder capable of capturing video, that is, a digital video camera (DVC), and a digital still camera (DSC) capable of capturing DVC and still images. And a composite photographing apparatus integrated into one case.

In recent years, as the photographing device is widely used, high-resolution, high-definition images have become a main function as well as simply recording or playing images as they are, and various functions are provided according to user's needs.

By the way, in the conventional photographing apparatus, it was not possible to edit files having different storage formats such as still images, moving images, and music files to generate one moving image file. Specifically, in the conventional photographing apparatus, it is possible to create a moving picture by pasting a plurality of still images. Or, it was possible to simply compose still images into previously saved movies.

In the conventional photographing apparatus, in order to edit a still image, a moving picture, a music file, and the like into a single moving picture file, the photographing device had to be connected to an editing device such as a PC capable of editing an image. In addition, the editing device had to store a dedicated program for editing.

Therefore, in the conventional photographing apparatus, it is not possible to generate a single video file by editing still images, videos, music files, etc., and to edit a still image, video, music files, etc., and to generate a single video file. Since it is necessary to connect to, not only the user's inconvenience is increased but also a lot of time is spent editing. In addition, a problem may occur in that image quality deteriorates during transmission of an image to be edited by the editing apparatus.

Accordingly, an object of the present invention is to provide an image editing method capable of editing files having different storage formats and a photographing apparatus to which the same is edited.

Another object of the present invention is to provide an image editing method capable of generating a single moving image file by editing previously stored still images, moving images, music files, and the like, and a photographing apparatus using the same.

The image editing method according to the present invention for achieving the above object comprises the step of receiving the editing information and editing the images having different storage formats based on the input editing information to generate a single image.

The editing information may include an arrangement position, a sequence, a reproduction length, a special effect function to be applied, and an application position of the images.

Specifically, in the generating step, it is preferable to generate the selected files among the pre-stored still image, moving image, and music file as one moving image based on the editing information.

In detail, the photographing apparatus according to the present invention receives an image processing unit for editing images having different storage formats based on the input edit information, and generates the single image, and receives the edit information based on the input edit information. And a controller configured to control the image processor to edit images having different storage formats into one image.

In addition, the image processor may be configured to generate files selected from previously stored still images, moving images, and music files into one moving image based on the editing information.

Hereinafter, with reference to the drawings will be described in detail the present invention.
