Automatic zoom for a display
View Patent ↗A method, apparatus, user interface and computer program product include the ability to determine a brightness characteristic of a display, use the brightness characteristic to determine a minimum and optimum font size for information displayed on the display, and automatically adjust the displayed information such that a size of a smallest font of the information is not smaller than the minimum font size and that a size of a main font of the information is not smaller that the optimum font size.
1. A method comprising: determining a brightness characteristic of a display; determining a minimum and optimum font size for information displayed on the display from the brightness characteristic from a table; and automatically adjusting the displayed information on the display using a module such that a size of a smallest font of the information is not smaller than the minimum font size and that a size of a main font of the information is not smaller than the optimum font size.
2. The method of claim 1 , further comprising determining a brightness characteristic of the display from contrast settings from a display driver.
3. The method of claim 1 , further comprising using a controller to determine the brightness characteristic of the display from a content of the display.
4. The method of claim 1 , further comprising determining a brightness characteristic of the display using a sensor.
5. The method of claim 1 , further comprising scaling other fonts in the information in relation to the minimum and optimum font sizes using the module.
6. The method of claim 1 , further comprising using the brightness characteristic to determine the minimum and optimum font size according to a user selected minimum and optimum font size stored in a table.
7. The method of claim 1 , further comprising using the brightness characteristic to determine the minimum and optimum font size according to a user's vision characteristics stored in a table.
8. The method of claim 1 , further comprising using the brightness characteristic to determine the minimum selected minimum and optimum font size according to a user's age stored in a table.
9. The method of claim 1 , further comprising using a manual control for manually adjusting font sizes of the displayed information after the automatic adjustment.
10. A computer program product comprising a non-transitory computer readable storage medium, the computer program product configured to, when executed, cause a processor to:
determine a brightness characteristic of a display;
determine a minimum and optimum font size for information displayed on the display from the brightness characteristic from a table; and
automatically adjust the displayed information on the display using a module such that a size of a smallest font of the information is not smaller than the minimum font size and that a size of a main font of the information is not smaller than the optimum font size.
11. An apparatus comprising: a device configured for determining a brightness characteristic of a display; and a module configured for determining a minimum and optimum font size for information displayed on the display using the brightness characteristic, the module further configured for adjusting the displayed information such that a size of a smallest font of the information is not smaller than the minimum font size and that a size of a main font of the information is not smaller than the optimum font size.
12. The apparatus of claim 11 , wherein the device comprises a display driver configured to provide contrast settings of the display for determining the brightness characteristic.
13. The apparatus of claim 11 , wherein the device comprises a display driver configured to provide the brightness characteristic from a content of the display.
14. The apparatus of claim 11 , wherein the device comprises a sensor for sensing the brightness characteristic.
15. The apparatus of claim 11 , wherein the module is further configured for scaling other fonts in the information in relation to the minimum and optimum font sizes.
16. The apparatus of claim 11 , further comprising a user configuration settings table for additionally determining the minimum and optimum font size according to a user selected minimum and optimum font size.
17. The apparatus of claim 11 , further comprising a user configuration settings table for additionally determining the minimum and optimum font size according to a user's vision characteristics.
18. The apparatus of claim 11 , further comprising a user configuration settings table determine the minimum selected minimum and optimum font size according to a user's age.
19. The apparatus of claim 11 , further comprising an input device configured for manually adjusting font sizes of the displayed information after the automatic adjustment.
20. A user interface comprising: a display having a brightness characteristic; a module configured for determining a minimum and optimum font size for information for presentation on the display using the brightness characteristic, and for adjusting the information such that a smallest font size of the information is not smaller than the minimum font size and a main font size of the information is not smaller than the optimum font size.
