Abstract
A signal processing device includes detection circuitry and correction circuitry. The detection circuitry includes a first detection unit and a second detection unit. The first detection unit generates at least one detection signal based on an associated one of output signals corresponding to each of at least two directions. The second detection unit has a broader detection range than the first detection unit and generates at least one correction signal based on the associated one of the output signals corresponding to each of the at least two directions. The correction circuitry corrects an associated one of the detection signals corresponding to each of the at least two directions with at least an associated one of the correction signals corresponding to at least one direction, other than one direction subjected to correction, out of the at least two directions.
