Abstract
The invention relates to a method for producing a series of modified images intended for forming an iridescent image, using at least one reference image, characterised by including steps of creating a color pallet (P); creating a series of at least two modified reference images (IRM0, IRM1, IRM2, IRMn, etc.), in which the colors of said at least one reference image (IR) are replaced with the colors of the pallet by applying, before or between each new modified reference image (IRM), a circular shift to the colors of the pallet. The invention also relates to the inter-laced, iridescent, 3-D images obtained using such a method, as well as to a device including such an interlaced image and an associated program.
Claims14
Method for producing an iridescent image from at least one reference image comprising a production of a series of modified images intended to form an iridescent image from at least one reference image, wherein the method comprises steps of:
- creating a palette of colours (P),
- creating a series of at least two modified reference images (IRM 0, IRM 1, IRM 2, IRM n, . . .), in which the colours of said at least one reference image (IR) are replaced by colours of the palette by effecting, before or between each new modified reference image (IRM), a circular shift of the colours of the palette, and
- creating an interlaced image from said at least two modified reference images,
- creating an iridescent image from said interlaced image, in which the series of at least two modified reference images in said interlaced image is put in relationship with an optical selector enabling an observer to perceive with his two eyes different images in said series.
A system for delivering an interlaced image for viewing comprising:
- a server with a processor,
- a data store containing at least one reference image and a colour palette, and
- an optical selector;
- wherein said interlaced image is derived by said processor from a series of at least two modified reference images (IRM 0, IRM 1, IRM 2, IRM n . . .) in said data store, said at least two modified reference images obtained from at least one reference image, the colours of said at least two modified reference images have been replaced by the colours of a palette of colours by performing, before or between each new modified reference image, a circular shift of the colours of the palette, and wherein the interlaced image forms an iridescent image in which the series of at least two modified reference images is put in positional relationship with the optical selector to enable an observer to perceive with his two eyes the different images in the series.
A device for delivering a 3D iridescent image to a viewer comprising
- a processor,
- a data store containing at least one reference image and a colour palette, and
- an optical selector;
- wherein said 3D iridescent image is derived by said processor from a series of modified reference images obtained from reference images constituting a stereoscopic pair stored in said data store, the colours of which have been replaced by said processor by the colours of a colour palette by performing, before or between each new modified reference image, a circular shift of the colours of the palette, and wherein the series of modified reference images in the iridescent image are put in positional relationship with the optical selector to enable an observer to perceive with his two eyes the different images in said series.
