Patent ID: 8749684

Claim:
An image data processing circuit comprising: a plurality of analog-to-digital converters, each respectively configured to convert an analog signal to a digital signal, each of the plurality of analog-to-digital converters including; a comparator unit configured to output a determination signal based on the analog signal; a storing unit configured to store a digital signal based on the determination signal; wherein an initializing switch sets an initial operating point before analog-to-digital conversion operation is initiated, and an intermittent operation includes at least one non-operating analog-to-digital converter, a first group of the initializing switches corresponding to operating analog-to-digital converters is in an ON state; and a second group of the initializing switches corresponding to non-operating analog-to-digital converters is periodically in an OFF-state, and further wherein the second group of initializing switches are selectively turned off during an image data thinning mode.
