Abstract
An image reading device includes: a solid-state image sensor for converting image information into an electric signal; an analog processing section for generating an analog processing signal by sampling and amplifying the electric signal at a sampling position; an A/D converting section for converting the analog processing signal into a digital signal; a pulse generating section for generating a control pulse to the solid-state image sensor, the analog processing section and the A/D converting section; and a control section for controlling a pulse generating timing of the pulse generating section, wherein the analog processing section comprises an amplification processing section for amplifying the electric signal so as to set an output voltage to a set voltage, the pulse generating section includes a varying section for varying the sampling position, and the control section includes an optimizing section for optimizing the sampling position based on variance of amplification gain values.
