Abstract
In an image reading device, a sampling-and-holding circuit generates a plurality of analog image signals by sampling an image signal at each sampling-and-holding timing and holding sampled image signals for a predetermined amount of time, an analog-to-digital converting unit converts the analog image signals into a plurality of digital image signals at each sampling-and-holding timing, a phase regulating unit performs phase regulation of each sampling-and-holding timing based on corresponding digital image signals to obtain phase-regulated sampling-and-holding timing. The sampling-and-holding circuit generates the analog image signal at each phase-regulated sampling-and-holding timing.
