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 scanning operation is synchronized with the motion of a scan mechanism. Encoder signals indicative of a position of the scan mechanism relative to a scan platen or an object being scanned are received. These encoder signals may include a single channel phase signals are channel A and channel B phase signals. Transitions of the encoder signals are detected. Scan pulses for triggering a scan operation by a scan element are generated based on transitions of the encoder signals. Differences in the encoder signal resolution and a desired scan resolution are compensated for in the generation of the scan pulses. A transfer signal is generated in synchronization with the scan pulses for controlling output of data from the scan element. Variations of the velocity of the scan mechanism cause variations of the frequency at which the scan pulses are generated. Variations in the velocity of the scan mechanism are accounted for during this synchronization by varying the duration of the transfer state of the transfer signal in relation to the variations of the scan pulse frequency. The duration of the exposure state of transfer signal is kept constant, ensuring a constant exposure time for the scanning device.
