Abstract
As to enhance the rendering while minimizing needed computation time, the method comprises the steps of determining noise information, said noise information being representative of noise level estimated for at least a part of said image; the noise information being determined for the achromatic component of the image; sampling said part of the image according to said noise information; and rendering said at least a part of the image according to said sampling.
Claims7
A method for rendering a first image, wherein the method comprises:
- dividing the first image in a plurality of first blocks of pixels;
- determining, by at least a processor, a noise information for each first block of pixels, said noise information being representative of at least a noise level determined for said each first block, the noise information being determined for an achromatic component of the first image;
- displaying said noise information in second blocks of pixels of on-a second image in a graphical way, each first block of pixels corresponding to one of the second blocks of pixels, the second image being different from the first image;
- sampling, by said at least a processor, said each first block of pixels of the first image according to the noise information displayed in the second block of pixels corresponding to said each first block, the sampling of said each first block of pixels being requested based on the noise information, said each first block of the first image being oversampled when said noise information is more than a threshold value;
- and
- rendering, by said at least a processor, said first image according to said sampling.
A device configured for rendering a first image, the device comprising:
- a memory;
- a processor configured to:
- divide the first image in a plurality of first blocks of pixels;
- determine a noise information for each first block of pixels, said noise information being representative of at least a noise level determined for said each first block, the noise information being determined for an achromatic component of the first image;
- display said noise information in second blocks of pixels of second image in a graphical way, each first block of pixels corresponding to one of the second blocks of pixels, the second image being different from the first image;
- sample said each first block of pixels of the first image according to the noise information displayed in the second block of pixels corresponding to said each first block, the sampling of said each first block of pixels being requested based on the noise information, said each first block of the first image being oversampled when said noise information is more than a threshold value;
- and
- render said first image according to said sampling.
