Abstract

A method of outputting graphics to a display comprising: detecting an input from a user representative of an image manipulation request; performing a first image manipulation process on at least part of the retrieved image data set in accordance with the image manipulation request to produce second graphics; outputting the second graphics to a display area of the display; determining that a boundary condition relating to the retrieved image data set has been satisfied, the boundary condition relating to a limit of the retrieved image data set beyond which there is no further element of the retrieved image data set to be displayed; performing a second image manipulation process on at least part of the retrieved image data set to produce third graphics, the second image manipulation process providing a second type of alteration to the retrieved image data set, the second type of alteration being of a different type than the first type of alteration; and outputting the third graphics to the display area of the display.

Claims

1. A method of outputting images on a display, the method comprising:

displaying at least first image on the display;

detecting an input representative of an image manipulation request;

performing a first image manipulation process providing a first alternation on a portion of the at least first image in accordance with the image manipulation request to display at least second image;

determining whether a boundary condition relating to the at least first image has been satisfied, the boundary condition relating to a limit of the at least first image set beyond which there is no further image to be displayed; and

in response to the boundary condition has been satisfied, performing a second image manipulation process providing a second alteration on a portion of the at least second image to display at least third image.

2. The method of claim 1, wherein the first alteration is a first type of geometric transformation applied to the at least first image and the second alteration is a second type of geometric transformation applied to the at least second image.

3. The method of claim 2, wherein the first alteration is a spatially uniform geometric transformation applied to the at least first image and the second alteration is a spatially non-uniform geometric transformation applied to the at least second image.

4. The method of claim 3, wherein a characteristic of the non-uniformity of the spatially non-uniform geometric transformation is dependent on a position of a representation of the input in relation to the display.

5. The method of claim 3, wherein the spatially uniform geometric transformation results in at least one of a translation of the first image in a general direction of the input, a stretching of the first image in the general direction of the input, a shrinking of the first image along two dimensions, a stretching of the first image along two dimensions to produce the second image.

6. The method of claim 5, wherein the spatially non-uniform geometric transformation results in a warping of the second image in the general direction of the input to produce the third image, wherein the degree of warping is dependent on the position of the input in relation to the display.

7. The method of claim 1, wherein performing the second image manipulation process comprising:

detecting a release of the input during the first image manipulation process; and

performing the second image manipulation process without a further input to produce the third image.

8. The method of claim 7 further comprises reversing the second image manipulation process, after the third image have been displayed, to produce at least fourth image.

9. The method of claim 1, wherein the determination of the boundary condition being satisfied comprises determining that at least one outer limit of the at least first image has met at least one outer limit of the display area.

10. The method of claim 1, wherein the image manipulation request corresponds to a representative movement of the input, the representative movement moving on the display towards at least one outer limit of the at least first image, or moving on the display away from at least one outer limit of the at least first image.

11. The method of claim 1, wherein the boundary condition relates to a single outer limit or two outer limits of the at least first image, and the second alteration is a one-dimensional image transformation applied to at least part of the at least first image or a two-dimensional image transformation applied to at least part of the at least first image.

12. The method of claim 1, wherein the image manipulation request comprises a zoom-out request or a zoom-in request, and wherein the determination of the boundary condition being satisfied comprises determining that a maximum zoom-out limit, beyond which no further image is present, or a maximum zoom-in limit, beyond which no further image is present, has been reached.

13. An apparatus for outputting graphics to a display, comprising:

at least one processor;

a display;

wherein operation of the processor causes the apparatus to;

display at least first image on the display;

detect an input representative of an image manipulation request;

perform a first image manipulation process providing a first alternation on a portion of the at least first image in accordance with the image manipulation request to display at least second image;

determine whether a boundary condition relating to the at least first image has been satisfied, the boundary condition relating to a limit of the at least first image set beyond which there is no further image to be displayed; and

in response to the boundary condition has been satisfied, perform a second image manipulation process providing a second alteration on a portion of the at least second image to display at least third image.

14. The apparatus of claim 13, wherein the first alteration is a first type of geometric transformation applied to the at least first image and the second alteration is a second type of geometric transformation applied to the at least second image.

15. The apparatus of claim 13, wherein the first alteration is a spatially uniform geometric transformation applied to the at least first image and the second alteration is a spatially non-uniform geometric transformation applied to the at least second image.

16. The apparatus of claim 13, the processor detects a release of the input representative of the image manipulation request during the first image manipulation process, and performs the second image manipulation process without a further input to produce the at least third image.

17. The apparatus of claim 13, wherein the processor determines that at least one outer limit of the at least first image has met at least one outer limit of the display area.

18. The apparatus of claim 13, wherein the image manipulation request corresponds to a representative movement of the input, the representative movement moving on the display towards at least one outer limit of the at least first image, or moving on the display away from at least one outer limit of the at least first image.

19. The apparatus of claim 13, wherein the boundary condition relates to a single outer limit or two outer limits of the at least first image, and the second alteration is a one-dimensional image transformation applied to at least part of the at least first image or a two-dimensional image transformation applied to at least part of the at least first image.

20. The apparatus of claim 13, wherein the image manipulation request comprises a zoom-out request or a zoom-in request, and wherein the determination of the boundary condition being satisfied comprises determining that a maximum zoom-out limit, beyond which no further image is present, or a maximum zoom-in limit, beyond which no further image is present, has been reached.
