Abstract

Data intended to be displayed on a higher resolution display such as a non-interlaced display used as a computer monitor may be converted for display on a lower resolution display such as an interlaced display. The conversion may be done in a way that preserves the intended frame format while enhancing readability. For example, in one embodiment, the frames intended for non-interlaced display may be preserved in size for display in the same frame format on a lower resolution interlaced display. Local magnification may be selectively implemented for particular regions to enhance the readability of those regions. Upon selection, such local magnification may provide pixel loss and color corrections in addition to local magnification. In this way the frame format may be preserved while enhancing readability.

Claims

1. A method of providing information for display on a lower resolution display comprising:

receiving data formatted for display on a higher resolution display in non-interlaced format;

providing information for display on a lower resolution display based on the data;

when the information is displayed on the lower resolution display, preserving a display size of the information and preserving intended frame format of the information;

selectively providing a zoomed-in region of the displayed information for display on the lower resolution display; and

performing pixel loss corrections on a portion of the zoomed-in region.

2. The method of claim 1, wherein the preserving a display size of the information comprises magnifying or de-magnifying a region that includes the information.

3. The method of claim 1, further comprising:

performing color corrections on a portion of the zoomed-in region.

4. The method of claim 3, further comprising:

locating high saturation colors which are sufficiently close to one another to result in color distortion and

adjusting saturation levels of the colors to reduce color distortion.

5. The method of claim 3, further comprising:

substantially correcting for hue differences between display of interlaced and non-interlaced information.

6. The method of claim 1, further comprising:

converting data formatted for display on a higher resolution non-interlaced display for display on a lower resolution interlaced display.

7. The method of claim 1, wherein providing information for display on a lower resolution display based on the data comprises converting data formatted for display on a higher resolution non-interlaced display for display on a lower resolution interlaced display.

8. A computer-readable medium having instructions stored thereon, which when executed by a machine, cause the machine to:

accept data formatted for display on a higher resolution display in non-interlaced format;

provide information for display on a lower resolution display based on the data;

identify regions of likely pixel loss in the information;

when the information is displayed on the lower resolution display, preserve a display size of the information, preserve an intended frame format of the information, and perform pixel loss corrections in a portion of the displayed information.

9. The computer-readable medium of claim 8, further comprising instructions stored thereon, which when executed by a machine, cause the machine to:

selectively zoom into a portion of the information for display on the lower resolution display and

locate lines of a less than a thickness and increase the thickness of the lines.

10. The computer-readable medium of claim 9, further comprising instructions stored thereon, which when executed by a machine, cause the machine to:

perform color corrections in a portion of the zoomed-in portion.

11. The computer-readable medium of claim 8, further comprising instructions stored thereon, which when executed by a machine, cause the machine to:

locate high saturation colors which are sufficiently close to one another to result in color distortion and

adjust saturation levels of the colors to reduce color distortion.

12. The computer-readable medium of claim 8, further comprising instructions stored thereon, which when executed by a machine, cause the machine to:

substantially correct for hue differences between interlaced and non-interlaced displays.

13. The computer-readable medium of claim 8, wherein to provide information for display on a lower resolution display based on the data, the machine is to convert data formatted for display on higher resolution non-interlaced display for display on a lower resolution interlaced display.

14. A system comprising:

a display and

a processor configured to;

receive data formatted for display on a higher resolution display in non-interlaced format,

provide information for display on a lower resolution display based on the data,

when the information is displayed on the lower resolution display, preserve a display size of the information and preserve an intended frame format of the information,

selectively zoom into a portion of the information for display on the lower resolution display, and

perform pixel loss corrections on a portion of the zoomed-in portion.

15. The system of claim 14, further comprising:

a video signal receiver communicatively coupled to receive data and provide the data to the processor.

16. The system of claim 14, wherein the processor is also configured to:

perform color corrections on a portion of the zoomed-in portion.

17. The system of claim 14, wherein the processor is also configured to correct for hue differences between interlaced and non-interlaced displays.

18. The system of claim 14, wherein to provide information for display on a lower resolution display based on the data, the processor is to convert data formatted for display on higher resolution non-interlaced display for display on a lower resolution interlaced display.
