BACKGROUND OF THE INVENTION
The present invention relates to a moving image editing system for processing and editing a moving image file using a computer.
[0002]
[Prior art]
Conventionally, various systems have been proposed for moving image editing systems.
For example, as a first system, as shown in FIG. 5, a still image as a component is extracted one by one from a moving image file composed of a collection of still images, and all the still images are extracted. A system has been proposed in which, after the extraction is completed, after processing each extracted still image, the still images are connected to form a moving image file.
[0003]
As a second system, as shown in FIG. 6, a system is proposed in which a moving image file of content prepared in advance is simply connected to the front or rear portion of a moving image file to be edited. Yes.
[0004]
As a third system, as shown in FIG. 7, the moving image file to be edited is divided into a moving image portion that needs to be processed and a moving image portion that does not need to be processed. Still images are extracted one by one, and when extraction of all the still images is completed, the extracted still images are processed one by one and then converted into a moving image file. Finally, a system for connecting a moving image portion that does not require processing and a processed moving image portion has been proposed.
[0005]
[Problems to be solved by the invention]
However, in the first system described above, after all the still images that are constituent elements are once extracted from the moving image file to be edited, the extracted still images are processed one by one, and the processing is completed. At that time, the edited still images are joined together to create a movie file after editing, so that there is a problem that it takes a long time to edit the movie file.
[0006]
Further, in the second system described above, since the contents prepared in advance are simply connected to the front part and rear part of the moving image file to be edited, special effects can be applied and various parts can be applied to the video switching part. Processing such as applying effects cannot be performed, and the edited moving image file will also be unrepresented.
[0007]
In the third system described above, the moving image portion to be processed is divided, the still image file is extracted from the divided portion, the extracted still image is processed one by one, and these still images are processed. Are connected to a moving image part that is not processed. For this reason, as in the first system described above, there is a problem that the editing process takes a long time. Furthermore, since the moving image file is divided into a portion to be processed in advance and a portion not to be processed before processing, there is a problem that a long processing time is required.
[0008]
The present invention has been proposed in view of the above-described problems, and an object thereof is to provide a moving image editing system capable of easily editing a moving image file and reducing the editing processing time. .
[0009]

[0010]
In the moving image editing system, image processing range setting means for setting whether to perform image processing processing on the entire image or to perform image processing processing on a specified range in the image processing processing. Prepare and configure.
[0011]
In the moving image editing system, the image processing range is gradually enlarged or reduced by combining the image processing range setting unit and the image processing time setting unit.
[0012]
Further, in the moving image editing system, an original frame for temporarily storing still image data extracted by the frame data extraction unit, white color image data, black color image data, and other still image data in a memory A data storage unit; and an image composition unit for combining the original image data stored in the original frame data storage unit and the image data processed by the image processing unit at a specified composition ratio. Configure.
[0013]
