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: 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.

The image formation apparatus includes an image carrier and a laser device for scanning the image carrier along a plurality of scan lines. Each scan line is divided into segments having segment boundaries in which the same segment boundary in adjacent scan lines are offset.
