Image display system and method
View Patent ↗A method of displaying an image with a display device including a plurality of display pixels includes receiving image data for the image, the image data including individual pixels of the image; buffering the image data and creating a frame of the image, the frame of the image including a plurality of columns and a plurality of rows of the pixels of the image; defining a first sub-frame and at least a second sub-frame for the frame of the image, image data of the second sub-frame being offset from image data of the first sub-frame by an offset distance of at least one pixel; and displaying the first sub-frame with a first plurality of the display pixels and displaying the second sub-frame with a second plurality of the display pixels offset from the first plurality of the display pixels by the offset distance.
1. A microprocessor-based process of performing logic operations comprising:
receiving image data for an image and buffering the image data to create a frame of the image;
generating a first sub-frame and at least a second sub-frame for the frame of the image, the at least the second sub-frame being spatially offset from the first sub-frame;
temporally displaying the first sub-frame with a first plurality of pixels of a display device and displaying the at least the second sub-frame with a second plurality of pixels of the display device offset from the first plurality of pixels to display the image; and
compensating for a defective pixel of the display device, including adjusting image data of at least one of the first sub-frame and the at least the second sub-frame corresponding to a location of the defective pixel in the displayed image.
2. The microprocessor-based process of claim 1 wherein adjusting the image data includes increasing an intensity of the image data of the at least one of the first sub-frame and the at least the second sub-frame corresponding to the location of the defective pixel in the displayed image.
3. The microprocessor-based process of claim 1 wherein adjusting the image data includes decreasing an intensity of the image data of the at least one of the first sub-frame and the at least the second sub-frame corresponding to the location of the defective pixel in the displayed image.
4. The microprocessor-based process of claim 1 performing logic operations further comprising:
receiving input regarding a presence of the defective pixel.
5. A process including operations comprising:
receive a frame of an image;
generate a first sub-frame and at least a second sub-frame for the frame of the image, the at least the second sub-frame being spatially offset from the first sub-frame;
provide the first sub-frame and the at least the second sub-frame to a display device for temporal display of the first sub-frame with a first plurality of pixels of the display device and display of the at least the second sub-frame with a second plurality of pixels of the display device offset from the first plurality of pixels to display the image; and
adjust image data of at least one of the first sub-frame and the at least the second sub-frame corresponding to a location of a defective pixel of the display device in the displayed image to compensate for the defective pixel.
6. The process of claim 5 wherein the operation of adjust the image data includes increase an intensity of the image data of the at least one of the first sub-frame and the at least the second sub-frame corresponding to the location of the defective pixel in the displayed image.
7. The process of claim 5 wherein the operation of adjust the image data includes decrease an intensity of the image data of the at least one of the first sub-frame and the at least the second sub-frame corresponding to the location of the defective pixel in the displayed image.
8. The process of claim 5 including operations further comprising:
receive input regarding a presence of the defective pixel.
9. A system comprising:
means for receiving a frame of an image;
means for generating a first sub-frame and at least a second sub-frame for the frame of the image, the at least the second sub-frame being spatially offset from the first sub-frame;
means for providing the first sub-frame and the at least the second sub-frame to a display device for temporal display of the first sub-frame with a first plurality of pixels of the display device and display of the at least the second sub-frame with a second plurality of pixels of the display device offset from the first plurality of pixels to display the image; and
means for adjusting image data of at least one of the first sub-frame and the at least the second sub-frame corresponding to a location of a defective pixel of the display device in the displayed image to compensate for the defective pixel.
10. The system of claim 9 wherein means for adjusting image data includes means for increasing an intensity of the image data of the at least one of the first sub-frame and the at least the second sub-frame corresponding to the location of the defective pixel in the displayed image.
11. The system of claim 9 wherein means for adjusting image data includes means for decreasing an intensity of the image data of the at least one of the first sub-frame and the at least the second sub-frame corresponding to the location of the defective pixel in the displayed image.
12. The system of claim 9 further comprising:
means for receiving input regarding a presence of the defective pixel.
