Abstract
An image scanner has an operation clock generator, a photoelectric converter, an AD converter configured to convert the analog pixel signals serially output by the photoelectric converter to digital pixel data by sampling the analog pixel signals in accordance with an operation clock generated by the operation clock generator, a data generator configured to generate read image data representing an read image of the original based on the pixel data converted by the AD converter, a resolution setter configured to set a reading resolution in the sub scanning direction, and a line period determiner configured to determine the line period to be (integer+decimal value) times a modulation period based on the reading resolution set by the resolution setter, the modulation period being inversion of the modulation frequency. The integer is greater than one and the decimal value is determined based on the reading resolution.
