Abstract: This invention is directed to image reading capable of suppressing EMI unwanted radiation while maintaining image quality. To accomplish this, the following processing is executed when reading an original image by a photoelectric transducer. More specifically, a first driving signal where SSCG spread modulation is applied, and a second driving signal where no SSCG spread modulation is applied are generated from a reference signal. Either the first or second driving signal is selected, and a timing signal for reading the original image is generated based on the selected driving signal. The image signal obtained by the photoelectric transducer is latched using the timing signal. The latched image signal is transferred for subsequent image processing. Upon reading a one-line image original, the second driving signal is selected till the completion of the latch operation, and after the latch operation, the first driving signal is selected for an image signal transfer operation.

Abstract: In a multiplied pulse generation device, a detection signal is outputted every time a driven object is driven by a specific amount. An actual cycle indicating a time interval between the detection signal and a previous detection signal is measured. An estimated cycle is estimated based on at least past two actual cycles including the actual cycle measured. A multiplied pulse is sequentially generated in such a manner that a multiplied cycle indicating a time interval per which the multiplied pulse is generated is sequentially changed according to an amount of change from the actual cycle to the estimated cycle.

Abstract: The invention concerns an image-forming apparatus employing a clock-generating circuit, which generates dot clock pulses utilized for an image-writing section of the image-forming apparatus. The clock-generating circuit includes a digital-delay dot clock adjusting section to generate first dot clock pulses having a predetermined number of pulses within a predetermined time interval at a constant exposing range of the image-writing section, wherein each period of the first dot clock pulses is slightly increased or reduced by changing a selection for a plurality of delayed clock pulses, which are generated by delaying clock-pulses, outputted from a reference oscillator, in slightly different delay times; and a jitter suppressing section to suppress a jitter component included in the first dot clock pulses, wherein the jitter suppressing section divides the first dot clock pulses to generate second dot clock pulses, and then, multiplies the second dot clock pulses to generate the dot clock pulses.

Abstract: There is provided an image forming apparatus that is capable of securing required printing quality by properly correcting a main scanning scale. In a pixel division modulating process, for each of one or more correction points (at l-th, m-th, and n-th pixels) on each of lines along which scanning is carried out on a photosensitive drum 11 by laser light, the final bit data of pixel-division-modulated pixel data of a pixel immediately preceding each correction point is added to the pixel data of a pixel located at the correction point as the leading bit data of the pixel-division-modulated pixel data of this pixel. The same processing as above is sequentially performed on pixel data of pixels located subsequently to the correction point to sequentially shift predetermined bit data of pixel data of pixels to pixel data of the respective following pixels, to thereby generate pixel data of a new pixel. The generated pixel data of the new pixel is outputted in synchronism with an image clock of a fixed frequency.
