Methods and apparatus for generating images
First Claim
Patent Images
1. A method of generating an image comprising a position identifying pattern and a content feature, the method comprising the steps of:
- generating the pattern and the content feature as a plurality of graphical pattern elements and a plurality of graphical content elements respectively, and superimposing the content feature and the pattern, wherein the content elements are smaller than the pattern elements in at least one dimension.

Abstract
A method of generating an image comprising a position identifying pattern and a content feature comprises the steps of: generating the pattern and the content feature each as a plurality of graphical elements, and superimposing the content feature and the pattern. The content elements are smaller than the pattern elements in at least one dimension.

- 35. A system for generating an image comprising a position identifying pattern and a content feature, the system being arranged to generate the content feature and the pattern, such that they are each made up of graphical elements and are superimposed on each other, and such that the elements of the content are smaller in at least one dimension than the elements of the pattern.

44. A system for applying a position identifying pattern to a product, the system comprising:
-
marking means arranged to apply pattern marks to the product to make up a position identifying pattern and content marks to the product to make up a content feature, and control means arranged to control the marking means so as to superimpose the content and the pattern on each other within at least an area of the product, said area having two dimensions, and within said area to make the content marks smaller than the pattern marks in at least one of the dimensions. - View Dependent Claims (51)

45. A product having a position identifying pattern and a content feature applied to it, wherein:
-
the pattern comprises as a plurality of discrete pattern marks, the content feature comprises a plurality of content marks, the content and the pattern are superimposed on each other within at least an area of the product, said area having two dimensions, and within said area the content marks are smaller than the pattern marks in at least one of the dimensions.

46. A method of analysing a position identifying pattern on a product, the product having on it the position identifying pattern comprising a plurality of pattern elements, and a content feature comprising a plurality of content elements, the content elements being smaller than the pattern elements, the method comprising the steps of:
-
forming an image of an area of the pattern and the content, and processing the image to extract the pattern from the content on the basis of the relative sizes of the pattern elements and the content elements. - View Dependent Claims (47, 53)

48. A system for identifying a position identifying pattern on a product, the product having thereon the position identifying pattern comprising a plurality of pattern elements and a content feature comprising a plurality of content elements, the content elements being smaller than the pattern elements in at least one dimension, the system comprising:
-
a sensor arranged to form an image of an area of superimposed pattern and content, and a processor arranged to process the image to extract the pattern from the content on the basis of the relative sizes of the pattern elements and the content elements. - View Dependent Claims (49, 50)
