Abstract
A frame 2 for an image such as a picture 16 is formed from a microlens array. Such an array produces an apparent optical plane which is not coplanar with the real plane of the array. This produces the visual effect of the picture 16 being divorced from the frame 2 and an illusion of depth is created as between the frame 2 and the picture 16.
Claims3
A frame for substantially enclosing the circumference of an image, the frame comprising a pair of arrays each comprising a plurality of paraboloidal or spherical lens type structures having a radial dimension within the micrometer to millimeter range, the arrays being superimposed on and spaced from one another, said arrays combining to form a resultant "bubble-like" pattern in a different plane to either array.
