That is, the video processing unit 10 may be divided into a decompression unit 12 which decompresses the video file and a data converter 14 which converts the decompressed data to obtain image data. have.

The decompressor 12 of the video processor 10 decompresses a video file using a Microsoft direct show. In particular, the direct show uses a direct show decoding filter to decompress the video file, and the format of the video file in the object is not limited to divX, Xivd, mp4, Mpeg, WMV,... In addition, the direct show is not limited to playing streaming (web) files.

In addition, the video processor 10 is provided with a data converter 14. The data converter 14 converts the data structure so that the video data decompressed by the decompressor 12 can extract the image data from the image extractor 20 to be described below.

For example, the data converter 14 converts the video data into 24-bit video data so as to obtain bitmap data from the video data.

In addition, the image extraction unit 20 is provided in the video image layer conversion apparatus of the present invention. The image extractor 20 extracts image data from video data processed by the video processor 10. This is to allow each image to be stacked in the layer converter 30 to be described below.

The image extracting unit 20 includes an image data extracting unit 22 for obtaining image data from video data, and an image data converting unit 24 for converting a file format so that the image data can be stacked. Can be configured.

The image data extractor 22 extracts image data from video data processed by the video processor 10. That is, the image data extractor 22 extracts bitmap data from the video data converted into the 24-bit format by the video processor 10.

 The image data converter 24 converts the data format to facilitate stacking of the bitmap data in the layer converter 30 to be described below. That is, the image data converter 24 converts the bitmap data extracted by the image data extractor 22 into 32-bit bitmap data. This is particularly intended to facilitate the alpha blending, image effects, and the like in the layer converter 30.

In addition, the layer image conversion unit 30 is provided in the video image layer conversion apparatus of the present invention. The layer converting unit 30 serves to stack each image data extracted by the image extracting unit 20 in various formats by an operator's manipulation.

The layer converter 30 includes a layer generator 32 for forming each image frame to which each image data is output, and a layer processor 34 for outputting the respective image data to the image frame. It is configured by.

The layer generator 32 sets a region in which the image data is output, that is, an image frame. That is, the worker may make an image frame in which the image data is output in various formats. For example, as illustrated in FIGS. 3B and 3C, the layer generator 32 may rotate and move the image frame. In this case, when there are several image data, the layer generator 32 may form an image frame in which each image data is output, and may be configured to overlap each image frame.

The layer processor 34 controls the respective image data to be output to the image frame generated by the layer generator 32. In addition, when the image frames overlap each other, the layer processor 34 may overlap the image data by alpha blending or the like.

Meanwhile, the display unit 40 is further provided in the video image layer converting apparatus according to the present invention. The display unit 40 allows the user to view the video image completed by the layer converter 30.

In addition, the video image layer converting apparatus is further provided with a controller 50, and the controller allows the user to control the video image layer converting apparatus. In particular, the layer converting unit 30 controls each of the video and the video, not the general image (Bitmap, Jpeg, Gif), the text (Layer) generated as a layer (Photoshop) and alpha blending, layer overlapping, It can be controlled in various forms such as image processing.

Hereinafter, the operation of the video image layer converting apparatus according to the present invention having the above-described configuration will be described in detail.

First, the user inputs a command signal to the control unit of the video image layer converting apparatus according to the present invention to select the video to be edited or output and output it in any position at any position (S10).

When a command signal is input to the controller, the video processor 10 opens the video (S12). That is, the video image layer conversion apparatus of the present invention is loaded from the folder or the Internet site where the video file is stored.

The layer processor 34 decompresses the video to generate a layer frame in which data is output (S14). If there are a plurality of videos, a plurality of layer frames will be generated.

When the layer frame is generated, the decompressor 12 of the video processor 10 decompresses the moving pictures on the layer frame (S16). In addition, there are a plurality of videos, and each video is decompressed separately so that each can be controlled independently.

The decompression of the moving images is decompressed by a direct show of Microsoft Corporation as described above. The video data decompressed by the decompressor 12 performs data conversion by the data converter 14 of the video processor 10 (S18).

In the data converter 14, the video data is converted into 24-bit video data. This is to obtain image data in bitmap format.

Next, the video data converted into 24 bits by the video processor 10 is performed by the image extractor 20 to extract the image data of the video. First, the image data extractor 22 of the image extractor 20 extracts bitmap data by reading header information from the 24-bit video data processed by the video processor 10 (S20).

The bitmap data is converted into 32-bit bitmap data by the image data converter 24 of the image extractor 20 (S22). The 32-bit bitmap data converted by the image data converter 24 is output in various formats by the user's control by the layer converter 30, which will be described in detail below.

First, the 32-bit bitmap data is outputted in the shape of the layer frame input by the user to the control unit in the layer generator 32 of the layer converter 30. At this time, the image data output to the layer frame is image-processed by the background of the display unit 40 or another image or text (S24).

That is, the image data output in the layer frame and the image such as the background screen may be variously output by alpha blending, layer overlapping, image processing, and the like as in Photoshop.

In addition, the user may adjust the output image of the image data by adjusting the rotation and scale of the layer frame through the control unit 50 (S26). As a specific example, it can be adjusted as shown in the drawings shown in Figures 3a to 3c.

Here, the layer frames may be formed as many as the number of moving images, that is, the number of image data, and the layer frames may be arranged to overlap each other. The overlapping portions of the frames are alpha blended or image-processed to output each layer frame (S28).

In addition, the layer frames on which the image data are output are various, such as alpha blending, layer overlapping, image processing, etc., as in Photoshop, with layer frames made of general images (Bitmap, Jpeg, Gif) and text, not video data. It can be output in the form.

The rights of the present invention are not limited to the embodiments described above, but are defined by the claims, and those skilled in the art can make various modifications and adaptations within the scope of the claims. Self-explanatory
