Patent ID: 7529424

Claim:
A camera having reduced distortion from an optical system comprising: a) an optical system which captures a wide field of view; b) an image sensor which captures a sensed image of said wide field of view through said optical system, and circuitry coupled to said image sensor and configured to convert the output of the image sensor to electrical signals suitable for use by an image processing circuit; c) the image processing circuit coupled to the image sensor and configured to provide a correction which reduces optical distortions from the combination of the optical system and the image sensor where the correction includes reference to a table of parameters held in a solid-state memory, attached to said image processing circuit, wherein the table of parameters are specific to the particular combination of said optical system and said image sensor; and d) wherein said table maps an individual pixel of a corrected output image to an accurate coordinate in the captured sensed image, wherein pixel values within a local neighborhood of the sensed image are used to provide a weighted sum which provides an estimate of the value at the said accurate coordinate on the sensed image, wherein the weight of each pixel within the local neighborhood is determined by its distance from the accurate coordinate provided by the table.
