Abstract
What is disclosed is a method comprising defining a scaling region by indicating in a CFA (Color Filter Array) a starting location, and generating a super-pixel which is a downscaled version of the scaling region, the super-pixel fully color interpolated, the downscaling and the color interpolation achieved in an integrated manner.
Claims19
A method comprising:
- defining a scaling region in a CFA (Color Filter Array) image;
- and
- generating a super-pixel which is a downscaled version of said scaling region, said super-pixel being fully color interpolated, by applying a mask to a sub-image region of the CFA image, said sub-image region having pixels of all the same color plane and normalizing the result of applying said mask to form a color component of said super-pixel, said color component having the color associated with the sub-image region.
An apparatus comprising:
- a scaling and color interpolation unit configured to transform CFA (Color Filter Array) pixels, each associated with only one of multiple color components, into downscaled super-pixels, each super-pixel having all of said color components, by applying a mask to a sub-image region of the CFA pixels, said sub-image region having pixels of all the same color plane and normalizing the result of applying said mask to form a color component of a super-pixel, said color component having the color associated with the sub-image region.
An article of manufacture comprising a computer readable medium having instructions stored thereon which when executed by a processor cause:
- a scaling region to be defined in a CFA (Color Filter Array) image;
- and
- a super-pixel which is a downscaled version of said scaling region to be generated, said super-pixel being fully color interpolated, by applying a mask to a sub-image region of the CFA image, said sub-image region having pixels of all the same color plane and normalizing the result of applying said mask to form a color component of said super-pixel, said color component having the color associated with the sub-image region.
