It was classified as any one layer selected from a layer and a texture layer. However, the present invention is not limited thereto, and the layer extractor 130 sets the RGB values of the pixels constituting the original image as default values, and classifies the layers into a layer composed of pixels having changed RGB values by adding or subtracting brightness and saturation values from the set default values. You may.

When the layer classification is completed in step S230, the controller 140 converts the size ratio so that each classified layer has the same size (S240).

Next, the control unit 140 stores the classified plurality of layers in the form of respective files, or merges them and stores them as one file, and then provides them in the form of a file compatible with the webtoon production program (S250).

In detail, the controller 140 may output a plurality of classified layers in the form of respective files, or may extract only some layers according to a user's request and output them in the form of a file.

Then, the controller 140 converts the output file to be compatible with the webtoon production program and provides it. For example, if it is assumed that the webtoon production program is a CLIP STUDIO painting program, the controller 140 selects the extension of the output file as *.jpg (*.jpeg) in the Clip Studio format or Converted to *.png file and output.
