| Abstract: |
The present invention provides a device for automatically creating a connect-the-dots drawing from an existing image. Edge detection techniques are used to determine the edges in an image and corner points are determined along the edges. The corner points are then ordered and outputted with numbers to create the connect-the-dots drawing.

I claim:
1. Apparatus for processing an image to automatically produce a connect-the-dots drawing based upon the image, comprising:
- memory storing image data representing the image;
- edge means for detecting edges in said image data;
- point means for determining corner points on said detected edges;
- ordering means for ordering said corner points and associating ordered numbers with said corner points according to the ordering of said corner points;
- printing means for printing dots at positions on a medium representing relative positions of said corner points and printing said numbers on the medium at locations near respective dots representing associated corner points.
