ELECTRONIC APPARATUS, CONTROL METHOD, AND IMAGE SENSOR

摘要

An electronic apparatus includes: a reference-signal output section that outputs a reference signal; a comparator that compares an electrical signal output from a pixel with the reference signal; a counter that obtains a count value as an AD conversion result of the electrical signal, the count value being obtained by counting time taken for the reference signal to change until the electrical signal and the reference signal match each other; and an auto-zero control section that performs control so that auto zero processing for setting the comparator is completed in a reset period, in which the pixel is reset, so that a comparison result indicating that two input signals supplied to the comparator match each other.

1. An electronic apparatus comprising:
a reference-signal output section configured to output a reference signal whose level changes; a comparator configured to compare an electrical signal output from a pixel having a photoelectric conversion element that performs photoelectric conversion with the reference signal output by the reference-signal output section; a counter configured to obtain a count value as an analog-to-digital (AD) conversion result of the electrical signal, the count value being obtained by counting time taken for the reference signal to change until the electrical signal and the reference signal match each other, based on a result of the comparison of the electrical signal with the reference signal; and an auto-zero control section configured to perform control so that auto zero processing for setting the comparator is completed in a reset period so that a comparison result indicating that two input signals supplied to the comparator match each other, the pixel being reset in the reset period.
