ABSTRACT:
An image processor includes an input device for inputting image signals, and a correcting device for correcting the image signals. A generating device generates a pulse-width modulation signal responsive to an image signal corrected by the correcting device, and a light emitting device emits light on the basis of the pulse-width modulation signal. A detecting device detects the pulse width of light emitted from the light emitting device, and a setting device sets correction conditions of the correcting device on the basis of the pulse width detected by the detecting device when a predetermined signal is supplied to the generating device.
