电子设备、控制方法和图像传感器
摘要：
本发明公开了电子设备、控制方法和图像传感器。所述电子设备包括：输出参考信号的参考信号输出部；把从像素输出的电信号与所述参考信号进行比较的比较器；求得计数值作为所述电信号的AD转换结果的计数器，所述计数值是通过对所述参考信号发生变换直至所述电信号与所述参考信号彼此一致时所花费的时间进行计数获得的；和自动调零控制部，所述自动调零控制部进行控制以使得在所述像素被复位的复位期间内完成用于设定所述比较器的自动调零处理，以此获得表示供给至所述比较器的两个输入信号彼此一致的比较结果。根据本发明，能够容易地抑制图像质量的降低。
摘要（英）：

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.
