ABSTRACT:
In a modulation method of this invention, light modulation is performed as follows. A light output from a light source, e.g., a semiconductor laser is increased with a lapse of time, and the light source is driven until a light strength corresponding to a desired exposure amount is obtained, so that a non-rectangular light output waveform such as a sawtooth or triangular wave is consequently obtained. A system of this invention is a system such as a high-precision image recording apparatus using this modulation method.
