Abstract

The invention relates to a method for providing an animation from prerecorded still pictures where the relative positions of the pictures are known. The method is based on prerecorded still pictures and location data, associated with each still picture, that indicates the projection of the subsequent still picture into the current still picture. The method comprises the repeated steps of providing a current still picture, providing the location data associated with the still picture, generating an animation based on the current still picture and the location data, and presenting the animation on a display. The invention provides the experience of driving a virtual car through the photographed roads, either by an auto pilot or manually. The user may change speed, drive, pan, shift lane, turn in crossings or take u-turns anywhere. Also, the invention provides a means to experience real time, interactive video-like animation from widely separated still pictures, as an alternative to video-streaming over a communication line. This service is called Virtual Car Travels.

Claims

1. Method for providing an animation from prerecorded still pictures where the relative positions of the pictures are known, the method comprising the following steps:

(a) providing a current still picture,

(b) providing location data indicating the location of a projection of a subsequent still picture into the current still picture,

(c) generating an animation based on the current still picture and said location data, and

(d) presenting said animation on a display.

2. Method according to claim 1, wherein said location data is derived from curve radius data associated with the current still picture, camera angle and the distance between the current still picture and the subsequent still picture.”

3. Method according to one of the claims 1-2, wherein said subsequent still picture is located within a sector of the current still picture.

4. Method according to one of the claims 1-3, wherein said step (c) of generating an animation comprises picture processing steps that result in a virtually continuous stream of events as experienced by a user.

5. Method according to claim 4, wherein said step (c) of generating an animation comprises the steps of

(c1) determining a segment of the current still picture corresponding to the projection of the subsequent still picture into the current still picture, and

(c2) generating a sequence of animated pictures derived from the current still picture by zooming, scrolling, and panning towards said segment.

6. Method according to one of the claims 1-5,

wherein said steps (a)-(d) are recursively repeated.

7. Method according to claim 6,

wherein said step (d) of presenting the animation comprises

setting the speed of the animation according to a user input.

8. Method according to claim 6 or 7,

wherein said step (d) of presenting the animation comprises

setting the panning of the animation according to a user input and camera angle.

9. Method according to one of the claims 1-8, performed by a client process, wherein said used still pictures correspond to a sequence of prerecorded still pictures provided by a server process, said current picture corresponding to a first picture in said sequence of prerecorded still pictures.

10. Method according to claim 9,

wherein said subsequent used still picture corresponds to the next picture in said

sequence of prerecorded still pictures.

11. Method according to claim 10,

wherein said subsequent used still picture corresponds to the second next, third next or fourth next picture in said sequence of prerecorded still pictures.

12. Method according to one of the claims 9-11,

wherein said subsequent used picture corresponds to the next, second next, third next or fourth next picture in said sequence, selected in accordance with a drive parameter set by a user input.

13. Method according to claim 9,

wherein said current used still picture is the last still picture in a unidirectional path terminating at a node in a network of unidirectional paths between nodes, and

wherein said subsequent used still picture corresponds to a still picture belonging to a path originating from said node.

14. Method according to claim 13,

said path originating from said node being selected in accordance with a turn parameter set by a user input or by default.

15. Method according to claim 9, wherein said used still picture is an intermediate picture in a unidirectional path, and wherein said subsequent used still picture corresponds to a still picture belonging to a parallel, identically directed path upon selection by a user input.

16. Method according to claim 9, wherein said used still picture is an intermediate picture in a unidirectional path, and wherein said subsequent used still picture corresponds to a still picture belonging to a parallel, oppositely directed path upon selection by a user input.

17. Method according to claim 9,

wherein said client process is performed by a client terminal and wherein said server process is performed by a server computer, said client terminal and said server computer being operatively interconnected by a communication network.

18. System for providing an animation from prerecorded still pictures where the relative positions of the pictures are known, the system comprising a computer arranged for performing a method according to one of the claims 1-17.

19. Client terminal for providing an animation from a prerecorded series of still pictures where the relative positions of the pictures are known, the client terminal being configured to perform a method according to one of the claims 1-17.

20. Computer program product, comprising computer instructions which causes a computer to perform a method according to one of the claims 1-17 when the instructions are executed by a processing device in the computer.
