Abstract

A progam is disclosed that restricts the visible portion of an still or motion digital image. The visibility is restricted at all times to prevent illegal copying of the image by means of capturing or otherwise such as printing or taking a picture. llegal capture prevention is requred in many cases since many copyright owners of the image do not want their images to be captured and misused, but want to show their images in good quality for commercial or non-commercial purposes.

PREVENTION SYSTEM OF IMAGE CAPTURING

A progam is disclosed that restricts the visible portion of an still or motion digital
image. The visibility is restricted at all times to prevent illegal copying of the image
by means of capturing or otherwise such as printing or taking a picture. llegal capture
prevention is requred in many cases since many copyright owners of the image do not
want their images to be captured and misused, but want to show their images in good
quality for commercial or non-commercial purposes.

         Visible portion(s) may be regarded as a "window". The window will move within the image
in a certain random fashion where it is difficult to predict the next position of the
window.

Previous methods of image capturing either degraded the quality of the image or
lacked portability and/or lacked security.

Typical implementation of this method are as follows.
1) The window will theoretically cover all the portions of the image over infinite period of
time, assuring there are no portions that will never be seen.
2)The window will move in a near random fashion.
3)The window will move relatively to the previous position, so that the human eyes can
follow the window rather easily.
4) The number of window is single, so that the human eyes will not be disturbed by multiple
moving windows.
5)The shape of the window maybe of any shape but preferably rectangle to offload the
calculation required.
6)The image does not move from its original position in any way, so that user will know...
