摘要： A beam light scanning device includes an image data processing unit operable to output image-processed data of neighboring pixels in such a way that the data is divided for distribution into first pixel data and second pixel data. The scanner also includes a synchronizer circuit that receives the first and second pixel data as output from the image data processor and outputs these pixel data while letting them be synchronized with clocks as synchronized based on a horizontal synchronous signal. The scanner further includes a couple of pulse width modulators or “PWMs”, a synthetic circuit, and a laser diode module. The PWMs are for adjustment of the pulse widths of the first and second pixel data as output from the synchronizer circuit respectively. The synthetic circuit combines together the pulse width-adjusted first and second pixel data. The LD emits a light beam indicative of the resultant combined pixel data.

摘要： An image forming apparatus comprises a light generator (e.g., laser) generating a scanning light beam and a driver driving the light generator depending on a drive signal to be provided. In this apparatus, data formed of image information at each pixel of each line along a main scan direction of an image to be targeted are distributed into a plurality of strings (i.e., channels) of data (e.g., two strings). Concerning each pixel provided by data in each string, information indicative of both a start and an end of modulation (e.g., PWM) is then produced. By using the start and end information, a modulator performs modulation depending on the data of each pixel in each string, providing a modulated signal. The modulated signals from the plural strings are mutually synthesized at synchronizes timings, being provided as the drive signal and given to the driver.
