"Don't care" pixel interpolation
First Claim
Patent Images
1. An image processor, comprising:
- an image receptor to receive an image, the image comprising care pixels and don'"'"'t care pixels, identification of care pixels and don'"'"'t care pixels being based, at least in part, upon a binary mask; and
an image smoother to smooth the image by altering a value of at least one don'"'"'t care pixel based, at least in part, on a weighted average of care pixels.

Abstract
A system and method facilitating image smoothing is provided. The invention includes an image processor having an image receptor and an image smoother. The invention provides for the image smoother to alter the value of a don'"'"'t care pixel based, at least in part, upon a weighted average of care pixels.

19. A method for smoothing an image, the method implemented by computer-executable instructions stored on computer-readable media, the method comprising:
-
determining a horizontal distance to a left care pixel and a value of the left care pixel;
determining a horizontal distance to a right care pixel and a value of the right care pixel;
determining a vertical distance to a top care pixel and a value of the top care pixel;
determining a vertical distance to a bottom care pixel and a value of the bottom care pixel;
calculating a smoothed value for a don'"'"'t care pixel based, at least in part, upon at least one of the horizontal distance to the left care pixel, the value of the left care pixel, the horizontal distance to the right care pixel, the value of the right care pixel, the vertical distance to the top care pixel, the value of the top care pixel, the vertical distance to the bottom care pixel and the value of the bottom care pixel; and
altering the don'"'"'t care pixel value based, at least in part, upon the calculated smoothed value.

20. An image processor, comprising:
-
means for determining a first distance to a first care pixel and a first value of the first care pixel;
means for determining a second distance to a second care pixel and a second value of the second care pixel;
means for calculating a smoothed value for a don'"'"'t care pixel based, at least in part, upon a weighted average of the first distance, the first value, the second distance and the second value; and
means for altering the value of the don'"'"'t care pixel based, at least in part, upon the calculated smoothed value.
