SIGNAL PROCESSING DEVICE AND METHOD, IMAGING ELEMENT, AND IMAGING DEVICE

摘要

A signal processing device and signal processing method are described herein. By way of example, the signal processing method includes a selection unit configured to select, based on a first comparison of an analog signal with a determination voltage, a selected reference voltage to be compared with the analog signal, the selected reference voltage being selected from a plurality of reference voltages. The plurality of reference voltages include at least a first reference voltage and a second reference voltage.
