Abstract
A signal processing device using a liquid crystal device having a plurality of pixels includes a storage unit that stores a signal which controls a level of transmittance in a plurality of pixels, a detection unit that, based on the signal that is stored in the storage unit, detects a first pixel associated with a second value which indicates higher transmittance than a first value, and a second pixel adjacent to the first pixel and associated with a fourth value which indicates the higher transmittance than a third value; and a correction unit that corrects the second value so that a difference of the transmittance indicated by the second value and the fourth value decreases. The third value indicates the higher transmittance than the first value, and the fourth value indicates a higher transmittance than the second value.
