1. A system comprising:
- an image analyzer to measure a blurriness level in an input image, said image analyzer comprising a sharpness detector configured to indicate blurriness of one or more edges of the input image over a range of one or more pixels; and
a processing unit configured to sharpen said input image using said blurriness level, said processing unit comprising a coefficient generator configured to utilize output of said sharpness detector to generate one or more pixel sharpening coefficients.

Abstract
A method includes analyzing an input image at least to determine locations of human skin in the input image and processing the input image at least to improve, on a per pixel basis, the areas of human skin of the input image. Another method included in the present invention includes measuring blurriness levels in an input image; and processing the input image with the blurriness levels at least to sharpen the input image. A third method includes identifying areas of at least bright light in an input image and changing the sharpness of the input image as a function of exposure level of different areas of the input image.
