Conversion of a sub-pixel format data to another sub-pixel data format

A color display for receiving source image data representing color images and for displaying to an average human observer color images corresponding to the source image data, the display comprising:

• a plurality of substantially identical pixel units tiled across a face of the display
• where each pixel unit includes a first plurality of independently drivable first subpixel display elements that can emit light of a first wavelength,
• where each pixel unit includes a second plurality of independently drivable second subpixel display elements that can emit light of a second wavelength,
• where each pixel unit includes an independently drivable third subpixel display element that can emit light of a third wavelength,
• said third wavelength being shorter than the second wavelength and said second wavelength being shorter than the first wavelength;
• wherein said first and second wavelengths contribute significantly to perception of luminance by the average human observer while the third wavelength does not contribute significantly to perception of luminance by the average human observer;
• wherein said first, second and third subpixel display elements are spatially distributed within their respective display pixel units according to a spatial distribution pattern different from an implied spatial distribution of implied first, second, and third color sensing elements that implicitly sampled an implied source image, where the implied samplings of the first, second, and third color sensing elements were implicitly used to generate said source image data,
• wherein for respective first, second, and third color sensing arrays defined by respective ones of said first, second, and third color sensing elements there are implied image source sampling areas,
• wherein for respective first, second, and third color display arrays defined by respective ones of said first, second, and third subpixel display elements there are implied image output resampling areas;
• and where said display further comprises:
• a respective sample-areas to resample-areas luminance contributions mapper provided for each of the first and second color display arrays that maps luminance contributions from hypothetically overlying ones of the implied image source sampling areas of the first and second wavelengths to hypothetically underlying ones of the implied image output resampling areas and thereby determines generated luminance signals that are used to drive the independently drivable first and second subpixel display elements of the display.
