Method and device for generating a presentation

1. A computer-implemented method of generating a presentation in accordance with a theme, wherein the presentation comprises at least one arrangement of graphic elements, and the theme defines the graphical appearance and layout of the graphic elements of the presentation, the method comprising:

generating a test image for display on an external display;

capturing a digital image of the test image displayed on the external display;

digitally analysing the captured digital image to identify properties of the external display;

selecting the theme for the presentation based on the analysis, wherein the selected theme individually alters the graphical appearance and layout of one or more graphic elements of the presentation, to improve the visibility of individual graphic elements when displayed on an external display with the identified properties; and,

generating the presentation in accordance with the selected theme.

2. The method according to claim 1 , wherein the presentation comprises a plurality of graphic elements of the same type, and wherein the theme defines the graphical appearance and layout of each graphic element independently of other content items of the same type.

3. The method according to claim 1 , wherein the presentation is not associated with a previously selected theme.

4. The method according to claim 1 , wherein selecting a theme comprises modifying a theme previously selected for the presentation.

5. The method according to claim 1 , wherein the theme comprises one or more characteristics, wherein each characteristic defines an aspect of the graphical appearance and layout of one or more graphic elements of the presentation, and wherein the one or more characteristics are selected from the group consisting of: type face, font weight, font size, font colour, image contrast, image saturation, font contrast, font saturation, background colour, background effect, slide transition, and slide animation.

6. The method according to claim 1 , wherein the test image comprises one of: a black and white image; red, blue and green regions; one or more geometric shapes; and a marker positioned substantially in each corner of the test image.

7. The method according to claim 1 , wherein digitally analysing the captured digital image comprises determining image sharpness of the captured digital image.

8. The method according to claim 7 , wherein, if the analysis determines that the image sharpness is below a predetermined threshold value, the selected theme comprises a large font size suitable for the text to be readable.

9. The method according to claim 1 , wherein, if the analysis determines that image contrast of the captured digital image is below a predetermined threshold value, the selected theme comprises one more characteristics selected from the group consisting of: a bold font weight, a non-light font weight, high image contrast, high font contrast, a light background with a dark font, and a large font size.

10. The method according to claim 1 , wherein, if the analysis determines that one or more colour discrepancies between the captured digital image and the test image are above a predetermined threshold value, the selected theme is based on the one or more colour discrepancies.

11. The method according to claim 1 , wherein capturing a digital image comprises using an internal camera.

12. The method according to claim 1 , further comprising displaying the test image on the external display.

13. An electronic device for generating a presentation in accordance with a theme, wherein the presentation comprises at least one arrangement of graphic elements, and the theme defines the graphical appearance and layout of the graphic elements of the presentation, the device comprising:

one or more processors; and,

memory comprising instructions which, when executed by one or more of the processors, cause the electronic device to:

generate a test image for display on an external display;

capture a digital image of the test image displayed on the external display;

digitally analyse the captured digital image to identify properties of the external display;

select the theme for the presentation based on the analysis, wherein the selected theme individually alters the graphical appearance and layout of one or more graphic elements of the presentation, to improve the visibility of individual graphic elements when displayed on an external display with the identified properties; and,

generate the presentation in accordance with the selected theme.

14. The electronic device according to claim 13 , wherein the presentation comprises a plurality of graphic elements of the same type, and wherein the theme defines the graphical appearance and layout of graphic elements independently of other content items of the same type.

15. The electronic device according to claim 13 , wherein the presentation is not previously associated with a theme.

16. The electronic device according to claim 13 , wherein selecting a theme comprises modifying a theme previously associated with the presentation.

17. The electronic device according to claim 13 , wherein the theme comprises one or more characteristics, wherein each characteristic defines an aspect of the graphical appearance and layout of one or more graphic elements of the presentation, and wherein the one or more characteristics are selected from the group consisting of: type face, font weight, font size, font colour, image contrast, image saturation, font contrast, font saturation, background colour, background effect, slide transition, and slide animation.

18. The electronic device according to claim 13 , wherein the test image comprises one of: a black and white image: red, blue and green regions; one or more geometric shapes; and

a marker positioned substantially in each corner of the image.

19. The electronic device according to claim 13 , wherein the analysis comprises determining image sharpness of the captured digital image.

20. An electronic device according to claim 13 , wherein, if the analysis determines that the image sharpness is below a predetermined threshold value, the selected theme is comprises a large font size suitable for the text to be readable.

21. An electronic device according to claim 13 , wherein, if the analysis determines that the captured digital image has contrast below a predetermined threshold value, the selected theme is comprises one or more characteristics selected from the group consisting of: a bold font weight, a non-light font weight, high image contrast, high font contrast, a light background with a dark font, and a large font size.

22. An electronic device according to claim 13 , wherein, if the analysis determines that one or more colour discrepancies between the captured image and the test image are above a predetermined threshold value, the selected theme compensates for the one or more colour discrepancies.

23. An electronic device according to claim 13 , wherein the device comprises a camera, and wherein the device is adapted to capture the digital image using the camera.

24. An electronic device according to claim 13 , wherein the device is adapted to display the test image on an external display.

25. A computer program product for generating a presentation in accordance with a theme, wherein the presentation comprises at least one arrangement of graphic elements, and the theme defines the graphical appearance and layout of the graphic elements of the presentation, the computer program product comprising a memory device comprising instructions which when executed by one or more of the processors of an electronic device cause the electronic device to:

generate a test image for display on an external display;

capture a digital image of the test image displayed on the external display;

digitally analyse the captured digital image to identify properties of the external display;
