Parallel dithering contour mitigation
A method of producing an image. Image data word comprising image data bits for a portion of the image is received at a first frame rate. At least two threshold data values are selected. A first portion of the image data word is compared with the threshold data values. A second portion of said image data word is displayed at a frame rate at least two times said first frame rate. Image data based on the comparison between the first portion of the image data word and the threshold data values is displayed at a frame rate at least two times the first frame rate.
1. A method of producing an image, the method comprising:
receiving an image data word at a first frame rate, said image data word comprising image data bits for a portion of said image;
selecting at least a first and a second threshold data value for said portion of said image;
comparing a first portion of said image data word with said first threshold data value;
comparing said first portion of said image data word with said second threshold data value;
displaying a second portion of said image data word at a frame rate at least two times said first frame rate;
displaying image data based on said comparing with said first threshold step at a frame rate at least equal to said first frame rate; and
displaying image data based on said comparing with said second threshold step at a frame rate at least equal to said first frame rate.
2. The method of claim 1 , wherein a three dimensional mask is used to select said threshold data values.
3. The method of claim 1 , wherein a different three dimensional mask is used to select each threshold data value.
4. The method of claim 1 , wherein at least two three dimensional masks are used to select each threshold data value.
5. The method of claim 4 , wherein said at least two three dimensional masks are complimentary.
6. A method of producing an image, the method comprising:
receiving an image data word during a frame period, said image data word comprising image data bits for a portion of said image;
selecting at least two threshold data values for said portion of said image;
comparing a first portion of said image data word with said at least two threshold data values;
displaying a second portion of said image data word at least two times during a display frame period;
displaying image data based on said comparing with a first threshold data value step during said display frame period; and
displaying image data based on said comparing with a second threshold data value step during said display frame period.
7. The method of claim 6 , wherein a three dimensional mask is used to select said threshold data values.
8. The method of claim 6 , wherein a different three dimensional mask is used to select each threshold data value.
9. The method of claim 6 , wherein at least two three dimensional masks are used to select each threshold data value.
10. The method of claim 9 , wherein said at least two three dimensional masks are complimentary.
