Abstract
One aspect of the disclosure is directed to an embedded device. The embedded device comprises an image of interest selecting mechanism and a transformation mechanism. The transformation mechanism applies perspective transformation functions to the image of interest such that the image of interest varies from a greater width at a foreground viewpoint of the image of interest to a lesser width toward a vanishing point of the image of interest and such that the image of interest varies from a greater amount of expansion and lesser amount of compression at the foreground viewpoint of the image of interest to a lesser amount of expansion and a greater amount of compression towards the vanishing point of the image of interest.
Claims31
An embedded device, comprising:
- an image of interest selecting mechanism;
- and
- a transformation mechanism to apply a perspective transformation function to the image of interest such that the image of interest varies from a greater width at a foreground viewpoint of the image of interest to a lesser width towards a vanishing point of the image of interest and such that the image of interest varies from a greater amount of expansion and lesser amount of compression at the foreground viewpoint of the image of interest to a lesser amount of expansion and a greater amount of compression towards the vanishing point of the image of interest.
A machine-readable medium encoded with data, the encoded data interoperable with a machine to cause:
- selecting an image of interest;
- and
- applying a perspective transformation to the image of interest such that the image of interest varies from a greater width at a foreground viewpoint of the image of interest to a lesser width towards a vanishing point of the image of interest and such that the image of interest varies from a greater amount of expansion and lesser amount of compression at the foreground viewpoint of the image of interest to a lesser amount of expansion and a greater amount of compression towards the vanishing point of the image of interest.
A mobile telephone, comprising:
- a receiver/transmitter assembly;
- a microprocessor;
- an image of interest selecting mechanism coupled to the microprocessor;
- and
- a transformation mechanism, coupled to the microprocessor, to apply a perspective transformation functions to the image of interest such that the image of interest varies from a greater width at a foreground viewpoint of the image of interest to a lesser width towards a vanishing point of the image of interest and such that the image of interest varies from a greater amount of expansion and lesser amount of compression at the foreground viewpoint of the image of interest to a lesser amount of expansion and a greater amount of compression towards the vanishing point of the image of interest.
Apparatus comprising:
- means for selecting an image of interest;
- and
- means for applying a perspective transformation to the image of interest such that the image of interest varies from a greater width at a foreground viewpoint of the image of interest to a lesser width towards a vanishing point of the image of interest.
