Hybrid scalar-vector dithering display methods and apparatus

An method for displaying an image, comprising:

• receiving an input image frame;
• generating a first set of color subfields based on the received input image frame;
• processing the first set of color subfields to obtain a second set of color subfields, the second set of color subfields including a larger number of color subfields than the first set of color subfields;
• executing a scalar dithering process on at least one color subfield of the second set of color subfields using a first dither mask;
• executing a vector dithering process across at least two color subfields of the second set of color subfields using a second dither mask;
• and
• causing the dithered second set of color subfields to be output on a display including an array of display elements, wherein the display further comprises:
• a processor capable of communicating with the display, the processor being capable of processing image data, and
• a memory device capable of communicating with the processor.

A computer readable medium storing instructions, which when executed by a processor, cause the processor to carry out a method, comprising:

• receiving an input image frame;
• generating a first set of color subfields based on the received input image frame;
• processing the first set of color subfields to obtain a second set of color subfields, the second set of color subfields including a larger number of color subfields than the first set of color subfields;
• executing a scalar dithering process on at least one color subfield of the second set of color subfields using a first dither mask;
• executing a vector dithering process across at least two color subfields of the second set of color subfields using a second dither mask;
• and
• causing the dithered second set of color subfields to be output on a display including an array of display elements, wherein the processor is capable of communicating with the display and processing image data, and wherein the display further comprises a memory device capable of communicating with the processor.
