Abstract
A method calibrates a camera having image sensor having a center position. An image view projected onto the image sensor by a lens is captured. At least one image view boundary of the captured image view is detected. A projection center position corresponding to a center of the projected image view is determined in at least one dimension. Offset between the projection center position and a sensor center position is determined, defined in at least one dimension, corresponding to the center of the image sensor capturing the projected image view. The image sensor is moved in relation to the lens based on the offset in order to arrive at a substantially zero offset in at least one dimension between the center of image sensor and the center of the projected image view.
