Abstract: An image is accurately recorded by a light beam on a PS plate wound on a drum which is rotating at a constant speed. A rotary encoder detects information of a recording position in a main scanning direction by the light beam that is emitted from an optical unit to the PS plate. Based on the detected information, a PLL circuit of a recording synchronizing signal generating unit generates an original clock. Pulses of the original clock are counted by a decimating counter, which outputs a decimating instruction to decimate a pulse from the original clock each time the count reaches a preset count. Based on the decimating instruction, a pulse is decimated from the original clock, and a decimated clock is frequency-divided at a fixed frequency-dividing ratio by a frequency divider, which outputs a pixel clock for recording the image. Since the frequency of the pixel clock is varied by decimating the original clock based on the preset count, the image can accurately be recorded on the PS plate by determining in advance the preset count depending on the positional relationship between the PS plate and the optical unit.

Abstract: A memory read control unit (606) reads out image data of one pixel from a memory (603) in synchronism with a clock signal. On the basis of the image data of one pixel, a converting unit (604) converts the density of a corresponding pixel into digital data of a plurality of bits and stores the digital data in a shift register (606). A pixel-piece insertion and deletion control unit (607) inserts data of one bit into the shift register or deletes data of one bit from the shift register. The pixel-piece insertion and deletion control unit (607) estimates a data storing state in the shift register and controls image data read-out from the memory (603) in accordance with the estimated data storing state.

Abstract: An image forming apparatus includes 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.

Abstract: A pixel clock generating apparatus comprises a data offset circuit and a pixel generator. The data offset circuit defines multiple data blocks, each data block consisting of a predetermined number of successive clocks, and produces phase data for each data block. The phase data represents an amount and a direction of phase shift to be carried out for a certain clock in each data block. The pixel generator receives the phase data from the data offset circuit and generates a phase-shifted pixel clock a predetermined number of times in each data block based on the phase data.
