Abstract
Transforming digital images including luminance data relating to points with first coordinates and chrominance data relating to points with second coordinates is performed. More particularly, the transforming is performed where one of the luminance data and the chrominance data is more numerous than the other. This is done by processing the least numerous data by filtering to obtain least numerous data relating to points with identical coordinates to those of the most numerous data.

A method of transforming a digital image comprising luminance data relating to points with first coordinates and chrominance data relating to points with second coordinates where the luminance data and the chrominance data are different in number so that ore of the luminance and chrominance data comprises most numerous data and the other comprises least numerous data, the method comprising:
- filtering the least numerous data to obtain least numerous data relating to points with identical coordinates to those of the most numerous data.
A method for transforming a digital image comprising luminance data relating to points with first coordinates and chrominance data relating to points with second coordinates where the luminance data and the chrominance data are different in number so that one of the luminance and chrominance data comprises most numerous data and the other comprises least numerous data, the method comprising:
- buffering pixels of the digital image comprising the least numerous and most numerous data;
- filtering the least numerous data from the pixels to obtain least numerous data relating to points with identical coordinates to those of the most numerous data to modify the pixels and change dimensions of the digital image;
- and
- arranging the modified pixels in a desired display order.
A system for transforming a digital image comprising luminance data relating to points with first coordinates,and chrominance data relating to points with second coordinates where the luminance data and the chrominance data are different in number so that one of the luminance and chrominance data comprises most numerous data and the other comprises least numerous data, the system comprising:
- a graphical processing system for changing dimensions of the digital image;
- said graphical processing system filtering the least numerous data to obtain least numerous data relating to points with identical coordinates to those of the most numerous data.
A system for transforming a digital image comprising luminance data relating to points with first coordinates and chrominance data relating to points the second coordinates where the luminance data and the chrominance data are different in number so that one of the luminance and chrominance data comprises most numerous data and the other comprises least numerous data, the system comprising:
- at least one memory providing a buffer for pixels of the digital image awaiting processing;
- a graphical processing system downstream from said at least one memory for changing dimensions of the digital image, the graphical processing system filtering the least numerous data to obtain least numerous data elating to points with identical coordinates to those of the most numerous data;
- and
- an arithmetic logic unit downstream from said at least one memory and said graphical processing system for arranging data received therefrom in a desired display order.
