Abstract:
An image reading system comprising:(A) an image reading apparatus comprising: (i) an image reading unit having a photoelectric conversion component for reading light from an image and converting the read image to an image signal; (ii) a driving motor for moving said image reading unit and the image relative to each other; (iii) a motor control unit for controlling said driving motor; (iv) a conversion circuit for performing analog-to-digital conversion on the image signal into image data; and (v) an image memory for storing the image data; and (B) an information processing apparatus comprising: (i) a temporary storage memory for reading and temporarily storing the image data stored in said image memory; (ii) a first timer for measuring the speed of the data stored in said temporary storage memory; and (iii) a control signal generating unit for outputting a motor control signal to said motor control unit based on the measurement of said first timer, wherein said motor control unit controls said driving motor according to the motor control signal output by said control signal generating unit, wherein, based on the measurement of said first timer, said control signal generating unit outputs the motor control signal which controls said driving motor so as to satisfy the relationship V1&lE;V2, where V1 represents a data speed at which the image is read to generate the image data, and V2 represents a data speed at which the image data is stored in said temporary storage memory, and wherein said motor control unit controls said driving motor according to the motor control signal.
