Abstract:
An improved form of optical security device for use in the protection of documents and articles of value from counterfeit and to verify authenticity is provided. The inventive device, which is made up of an optionally embedded array of icon focusing elements, at least one grayscale in-plane image, and a plurality of coextensive control patterns of icons contained on or within the in-plane image, each control pattern being mapped to areas of the grayscale in-plane image having a range of grayscale levels, provides enhanced design capability, improved visual impact, and greater resistance to manufacturing variations.

Claim (Index 15):
The method of  claim 14 , further comprising:\n selecting a sequence of grayscale in-plane images to form an animation; scaling the grayscale images to a size suitable for use in the icon layer; superimposing a tiling onto each scaled grayscale in-plane image, the tiling comprising cells to contain the control patterns of icons; selecting a numerical range to represent the colors black and white and at least one gray; determining a level of grayscale of the scaled grayscale in-plane image in each cell of the superimposed tiling; assigning to each cell of the superimposed tiling, a number associated with the determined level of grayscale and falling within the selected numerical range, wherein the assigned number is the cell's grayscale value; for each grayscale in-plane image that forms the animation, selecting a number of control patterns of icons for use in a control pattern palette, and for each control pattern of icons, assigning a range of grayscale levels falling within the selected numerical range, wherein the selected number of control patterns of icons constitutes a set of control patterns for the grayscale in-plane image, with each grayscale in-plane image having one set of control patterns of icons; specifying, for each set of control patterns of icons, a control pattern probability distribution within the respective in-plane image and for each possible grayscale value, using the control pattern probability distribution to assign a range of random numbers to each control pattern; providing each cell in the tiling with a random number that falls within the selected numerical range using a random number generator; determining, for each set of control patterns, each set being assigned to a specific and different grayscale image, a control pattern will be used to fill each cell based on the cell's grayscale value and the control pattern probability distribution; and filling each cell with its determined control pattern of icons, each cell receiving a determined control pattern from each set of control patterns of icons.
