20. A method for controlling a sensing device, the method comprising:
a level control step of amplifying or attenuating a signal level of one of a pair of pixel signals by a predetermined gain;
a comparison step of comparing the pair of pixel signals with the signal level of the one pixel signal amplified or attenuated with each other, and outputting a result of the comparison; and
an edge determination step of determining whether an edge is present or absent in reference to the comparison result.
