The initial value T of the period of a four-phase driving signal for driving a CCD of an image pickup device is calculated according to the equation T &equals;(L&times;p)/(f&times;v). Wherein, L represents the distance from the CCD to a product (object), if represents the focus length of the optical system used between the CCD and product, v represents the transferring speed of the product, and p represents the distance interval of photodiodes of the CCD. Afterward, the period T of the driving signal is adjusted properly depending on the pickup position of the product. Because electric charges corresponding to the same portion of the image of the product are accumulated in the same potential well formed by the driving signal by generating the driving signal as described above, the image of the product is picked up with suppressed blurring regardless of the speed of the product. Blurring is prevented during image pickup of an transferring object by the method described above.
