摘要 |
An image processing apparatus comprises image signal input means, tone means for toning the input image signal to produce a pulse width modulated signal, beam generation means for generating a beam modulated by the pulse width modulated signal, and detection means for detecting an output power of the beam generated by the beam generation means. The tone means switches an output mode of the pulse width modulated signal in accordance with the detection output of the detection means.
