Density adjusting method in image recording |
摘要 |
In a process of image recording by scanning a recording material with a light beam modulated by an image signal, the density of the recorded image is adjusted by controlling the light intensity during a predetermined interval using a clock pulse for picture elements, recording an image for a predetermined time within the predetermined interval, and changing the predetermined recording time for the entire image or only portions thereof. The recording time is changed in a very simple manner, for example, by operating a variable resistor.
