摘要

Refers to a method for Differentiating between the bottom and the front of a decorated Images recorded by an electronic Camera, the background shows an arbitrary Image encoded with a Coding so that the image to be recognizable to a direct Observer of the Fund,And the Fund is not encoded in a Signal produced by an Image Sensor of the camera Recording images by encoding.Since the encoding that covers the bottom shows the image as a sequence of periodic components that make up the image, having at least one parameter images on the display of the image that changes respectively in the course of each period.And an Exhibition of Images from the camera sensor made synchronously with the display of a specific component. Applied in the media to introduce a foreground Image in a background image, i.e., embedding, Reverse effect, and the switching controlled by the Saturation of color
