As operation modes, a sensor row driver (5) has: (a) a sensor drive mode in which a sensor drive signal of a first pattern is supplied, and a photosensor signal that corresponds to the amount of light received by the photosensor is output to a signal processing circuit (8), and (b) a correction data acquisition mode in which a sensor drive signal of a second pattern that is different from the first pattern is supplied, and a correction photosensor signal level that corresponds to the case where the photosensor detected a black level or a white level is acquired. The photosensor signal levels obtained in the two modes while the ambient environment is controlled to a predetermined condition are stored in a memory. The signal processing circuit (8) corrects the photosensor signal in the sensor drive mode using the correction photosensor signal level that was corrected using the data for resolving offset.
