Abstract
An apparatus and a method for correction of a deviation of an imaging sensor of a digital camera in which an image of an object or a scene is formed on an image plane of the imaging sensor to output an image signal, are disclosed. A quantity of rotation of the digital camera causing a deviation of the imaging sensor from a reference position to occur, is detected. A change of a positional angle of the imaging sensor is calculated based on the detected rotation quantity. A target vector is calculated based on the calculated positional angle change, the target vector describing a magnitude and a direction of an inverse movement of the imaging sensor needed to reach the reference position and cancel the deviation. Movement of the imaging sensor is controlled based on the calculated target vector, so that the imaging sensor is moved back to the reference position thus correcting the deviation. The calculation of the target vector and the movement of the imaging sensor are executed within an image acquisition time for a single frame of the image signal.
