Abstract
An improved method and apparatus for enhancing the resolution of an image of an object by a sensor is described by operating the sensor to capture a two-dimensional image of the object. In particular, one of the sensor and the object is moved with respect to the other from a first position to a second position. In the second position, electrical signals are outputted by the sensor's pixels aligned with a sampling line that is disposed at an acute angle with respect with a reference line of the object, whereby the resolution of the resultant object image is enhanced.
