Abstract
Apparatus comprising a digital camera (or image capture device) and thin, deformable image sensor that is flexed to correct for sensor deformities and/or lens aberrations. The image sensor has attachments (piezoelectric devices) on its rear surface. The deformable attachments are electrically coupled to processing circuitry comprising firmware that deforms the sensor by digitally controlling the respective deformable attachments to vary the flatness of the sensor. This allows for correction of field flatness and some other lens aberrations. The sensor may be tilted, or deformed into concave or convex shapes, for example, to correct for flatness irregularities.
