摘要
An image sensor formed with shifts among the optical parts of the sensor and the photosensitive parts of the sensor. Exemplary methods of calculating the desired shift are described and include a circular, symmetric design for the shift. The exemplary methods can also be used to calculate a correction coefficient for performing shading correction on signals that are output from the array and digitized.
