Abstract
A position detecting device includes an image sensor and circuitry. The image sensor is configured to read reflected light of light emitted from a light source onto a medium to be read. The circuitry is configured to perform black correction processing on an output signal of the image sensor using black correction data of the image sensor and detect a position of the medium from the output signal after the black correction processing.
