摘要： To read an image with high resolution via a CCD linear sensor having a limited pixel count, an image reading apparatus includes: a CCD linear sensor having arranged in a main-scanning direction photoelectric conversion elements for receiving a light reflected from an original; a piezoelectric element for providing a relative displacement between a light receiving surface of the CCD linear sensor and an object's image formed on the light receiving surface, according to a predetermined oscillation function and in the main-scanning direction; and a sensor drive circuit timing the CCD linear sensor's charge accumulation. The sensor drive circuit uses a distance from a center of an amplitude of the relative displacement to the CCD linear sensor and a time period of charge accumulation by the CCD linear sensor to determine a time point to start charge accumulation. The apparatus also includes a signal synthesizing circuit using image signals output from the CCD linear sensor during one period of the predetermined oscillation function to reconstruct an image signal of one line.
