Abstract
A digital camera system includes a camera body; a lens mounted to the camera body, and an image processor operatively coupled to the lens. The image processor converts a visual image passing into the lens to a digital format to form a captured digital image. The digital camera system also includes an angle sensor mounted in the camera body. The angle sensor, in the form of a multi-spot focus angle sensor, determines a camera angle position and outputs camera angle position data. A distortion processor operatively coupled to the digital camera receives the camera angle position data obtained from the sensor and the captured digital image from the image processor to selectively remove distortions associated with the camera angle position to form a corrected digital image.
