Abstract
Herein described is a method and system of vertically filtering a graphics image such that an enhanced image is provided to a display. Filtering of the graphics image may be accomplished by using one or more window descriptors. The method may be implemented by computing a weighted average of one or more pixel intensities. The system may comprise a memory, a processor, and a graphics engine. The graphics engine may comprise a graphics blender. The graphics blender may comprise one or more multipliers and one or more adders. The processor may execute software resident in the memory, such that the one or more window descriptors may be used to compute the weighted average.
Claims23
A method, comprising:
- assigning, using circuitry, a first value to a first parameter of a first window descriptor for a single graphics image;
- assigning, using the circuitry, a second value to a second parameter of a second window descriptor for said single graphics image;
- multiplying, using the circuitry, said first value and a first pixel intensity associated with a first pixel of said first window descriptor to yield a first product;
- multiplying, using the circuitry, said second value and a second pixel intensity associated with a second pixel of said second window descriptor to yield a second product;
- and
- adding, using the circuitry, said first product to said second product to yield a sum, said sum providing a vertically filtered pixel intensity for said single graphics image.
A system, comprising:
- circuitry operable to:
- assign a first value to a first parameter of a first window descriptor for a graphics image, the first window descriptor being for a first interlaced scanning field;
- assign a second value to a second parameter of a second window descriptor for the graphics image, the second window descriptor being for a second interlaced scanning field;
- multiply said first value and a first pixel intensity associated with a first pixel of said first window descriptor to yield a first product;
- multiply said second value and a second pixel intensity associated with a second pixel of said second window descriptor to yield a second product;
- and
- add said first product to said second product to yield a sum, said sum providing a vertically filtered pixel intensity for the graphics image.
A method, comprising:
- associating, using circuitry, a first value with a first parameter of a first window descriptor for a single graphics image;
- associating, using the circuitry, a second value with a second parameter of a second window descriptor for the single graphics image;
- multiplying, using the circuitry, the first value and a first pixel intensity for a first pixel of the first window descriptor to yield a first product;
- multiplying, using the circuitry, the second value and a second pixel intensity for a second pixel of the second window descriptor to yield a second product;
- and
- adding, using the circuitry, the first product to the second product to yield a vertically filtered pixel intensity for the single graphics image.
A system, comprising:
- a graphics engine comprising circuitry, the circuitry operable to:
- obtain a first value for a first parameter of a first window descriptor for a single graphics image;
- obtain a second value for a second parameter of a second window descriptor for the single graphics image;
- multiply the first value and a first pixel intensity for a first pixel of the first window descriptor to yield a first product;
- multiply the second value and a second pixel intensity for a second pixel of the second window descriptor to yield a second product;
- and
- add the first product to the second product to yield a vertically filtered pixel intensity for the single graphics image.
