Abstract
A method and a device for generating a pixel value from a plurality of sample values being generated from a plurality of sample points. The method comprises generating a plurality of sample values; and weighting said plurality of sample values for determining said pixel value. Each sample value is generated from one of a plurality of candidate sample points within a sample region. The sample region is positioned at a corner of two intersecting borders of the pixel. The size of the sample region is smaller than the size of the pixel. The device is arranged to carry out the method according to the invention.
Claims23
A method for generating a pixel value from a plurality of sample values, comprising:
- selecting a single sample from each of a plurality of sample regions, each sample region being positioned at a corner of two intersecting borders of said pixel and the size of each sample region being smaller than the size of the pixel and each sample region being both partly outside and partly inside said pixel;
- generating said pixel value from said selected sample values, at least one of said samples being positioned outside said pixel.
A device for generating a pixel value from a plurality of sample values, comprising:
- a sampling device for selecting a single sample from each of a plurality of sample regions, each sample region being positioned at a corner of two intersecting borders of said pixel and the size of each sample region being smaller than the size of the pixel and each sample region being both partly outside and partly inside said pixel;
- and
- a calculation device for calculating said pixel value from said selected sample values, at least one of said samples being positioned outside said pixel.
A computer program product comprising computer program code means to execute a method when said computer program code means is run by an electronic device having computer capabilities, the method comprising:
- selecting a single sample from each of a plurality of sample regions, each sample region being positioned at a corner of two intersecting borders of said pixel and the size of each sample region being smaller than the size of the pixel and each sample region being both partly outside and partly inside said pixel;
- generating said pixel value from said selected sample values, at least one of said samples being positioned outside said pixel.
