Patent attributes
Provided is a signal processing device including a signal synthesis unit that generates a first synthesis signal configured from an image signal to cause a first light emitting element used for displaying an image to emit light and a dummy pixel signal to cause a second light emitting element used for measuring brightness to emit light, a conversion unit that converts the generated first synthesis signal into a second synthesis signal to cause only the first light emitting element of the first light emitting element and the second light emitting element to emit light at identical brightness, regardless of a degradation degree of the first light emitting element, and a light emission control unit that causes the first light emitting element and the second light emitting element to emit light, on a basis of the second synthesis signal.
