Patent ID: 8736722

Claim:
An image capture sharpening subsystem of a digital camera, the image capture sharpening subsystem comprising: a first memory that stores values for a capture sharpening amount, the values for the capture sharpening amount based on calibration of an optical subsystem of the digital camera during a manufacturing process and being a function of position on a surface of an image sensor of the digital camera that captures an image; a capture sharpening processor receives a first value for a pixel in the image captured by the image sensor, the first value being associated with a position of the pixel on the surface of the image sensor, determines a pixel sharpening amount from the values for the capture sharpening amount stored in the first memory according to the position of the pixel on the surface of the image sensor, applies a capture sharpening process to the first value for the pixel to provide a second value for the pixel according to the pixel sharpening amount, the capture sharpening process enhancing contrast of transitions in brightness, and stores the second value in a second memory that provides a sharpened version of the image captured by the image sensor.
