ABSTRACT:
An electronic apparatus includes: an AD conversion section that has a comparing section, which receives a reference signal whose level changes gradually from a reference signal generating section that generates the reference signal and which compares the reference signal with an analog signal to be processed, and a counter section, which receives a count clock for AD conversion and performs a count operation on the basis of a comparison result of the comparing section, and that acquires digital data of the signal to be processed on the basis of output data of the counter section; a count operation period control section that controls an operation period of the counter section in each processing period on the basis of the comparison result of the comparing section; and a driving control section that controls the reference signal generating section and the AD conversion section.
