IMAGING DEVICE, IMAGING SYSTEM, AND IMAGING METHOD

An imaging device includes an imaging unit configured to generate image data on the basis of a first power voltage; an image processing unit configured to perform image processing on the image data onthe basis of a second power voltage; a reference voltage generating unit configured to generate a first reference voltage on the basis of the first power voltage; and a first flag generating unit configured to generate a first flag signal for the second power voltage on the basis of a comparison of the second power voltage and the first reference voltage and configured to output the first flag signal. 成像设备包括：成像单元，其被构造成基于第一电源电压生成图像数据；图像处理单元，其被构造成基于第二电源电压对所述图像数据执行图像处理；参考电压生成单元，其被构造成基于所述第一电源电压产生第一参考电压；以及第一标志生成单元，被构造成基于所述第二电源电压与所述第一参考电压的比较产生用于所述第二电源电压的第一标志信号，并且被构造成输出所述第一标志信号。
