Abstract:
1. An imaging device comprising: a unit pixel that outputs an analog electric signal in accordance with a signal charge generated the unit pixel; a reference signal generation section that generates a reference signal used for conversion of the analog electric signal output from the unit pixel into a digital signal; a local voltage supply circuit that generates a local voltage different from an operation voltage, the local voltage being provided to the reference signal generation section, and the reference signal generation section, based on the local voltage from the local voltage supply circuit, generating the reference signal for the conversion of the analog electric signal output from the unit pixel into the digital signal; and a processing section that receives the reference signal from the reference signal generation section and converts, by referring to the reference signal generated by the reference signal generation section, the analog electric signal output from the unit pixel into the digital signal, wherein,
