Abstract

At least one region of interest within an image is determined, step 201. The image is resized to a target image size step 207. If at least one region of interest is determined the image is cropped to each of the at least one region of interest, step 205 and the cropped at least one region of interest is resized to the target image size. The re-sized image and the resized cropped at least one region of interest are stored for display, step 209.

Claims

1. A method for providing an image for display, the method comprising the steps of:

determining at least one region of interest within an image;

resizing said image to a target image size;

if at least one region of interest is determined, cropping said image to each of said at least one region of interest;

resizing said cropped at least one region of interest to said target image size;

storing said resized image and said resized cropped at least one region of interest for display.

2. A method according to claim 1, wherein the step of resizing said image to a target image size comprises the steps of:

determining the size and aspect ratio of said target image;

determining the size and aspect ratio of said image;

determining a scaling factor from said determined size of said target image and size said determined size of said image; and

resizing said image according to said determined scaling factor.

3. A method according to claim 2, wherein the step of resizing said cropped at least one region of interest to said target image size comprises the steps of:

determining the size and aspect ratio of said cropped at least one region of interest;

determining a scaling factor from said determined size of said target image and said determined size of said cropped at least one region of interest; and

resizing said cropped at least one region of interest according to said determined scaling factor whilst maintaining said determined aspect ratio of said cropped at least one region of interest.

4. A method according to claim 3, wherein the step of resizing said cropped at least one region of interest according to said determined scaling factor whilst maintaining said determined aspect ratio comprises the steps of:

extending said cropped at least one region of interest to include at least a portion of said image outside of said cropped at least one region of interest such that the extended at least one region of interest has an aspect ratio corresponding to said determined aspect ratio of said image;

cropping said image to said extended at least one region of interest; and

resizing said cropped extended at least one region of interest to said target image size.

5. A method according to claim 1, wherein the method further comprises the step of:

selecting a stored, resized image of said image or said stored, resized cropped at least one region of interest of said image.

6. A method according to claim 5 further comprising the step of:

displaying said selected, stored image.

7. A method according to claim 1, wherein the step of determining at least one region of interest within an image comprises the step of:

automatically detecting at least one region of interest within an image.

8. A method according to claim 7, wherein the step of cropping said image to each of said at least one region of interest comprises the steps of:

extending said detected region of interest to include a portion of said image outside of said detected at least one region of interest;

cropping said image to said extended at least one region of interest.

9. A method according to claim 1, wherein the step of determining at least one region of interest within an image comprises the step of:

manually defining at least one region of interest within an image.

10. A computer program product comprising a plurality of program code portions for carrying out the method according to any claim 1.

11. Apparatus for providing an image for display, the apparatus comprising:

determining means for determining at least one region of interest within an image;

a processor for resizing said image to a target image size and, if at least one region of interest is determined, cropping said image to said at least one region of interest and resizing said cropped at least one region of interest to said target image size;

storage means for storing said resized image and said resized cropped at least one region of interest for display.

12. Apparatus according to claim 11 further comprising:

a display for displaying said stored image.

13. Apparatus according to claim 11, wherein said determining means includes a detector for automatically detecting at least one region of interest within an image.
