摘要： To reduce fluctuations in image signals when the voltage of a negative power supply supplied to pixels changes. A pixel operates based on a first ground potential applied to a first ground line and outputs an analog image signal according to emitted light. An analog-digital converter operates based on a second ground potential applied to a second ground line, the second ground potential higher than the first ground potential, and converts the analog image signal into a digital image signal based on a reference voltage as a standard for the conversion. A reference voltage generation unit operates based on the second ground potential and generates the reference voltage. A reference voltage correction unit corrects the reference voltage generated according to a change in the first ground potential and supplies the reference voltage to the analog-digital converter.

摘要： An image signal output unit is controlled in accordance with a first control signal indicating either voltage state of an on voltage for causing a conductive state and an off voltage having a polarity different from that of the on voltage, and outputs an analog image signal corresponding to the electric charge held by an electric charge holding unit in the conductive state. A reset unit is controlled in accordance with a second control signal indicating either voltage state of the on voltage and the off voltage, resets the electric charge holding unit in the conductive state, transmits a fluctuation in the off voltage to the electric charge holding unit, and fluctuates the analog image signal. A reference signal generation unit generates a reference signal being a signal serving as a reference used when conversion from an analog image signal output from the image signal output unit into a digital image signal is performed. A reference signal correction unit corrects the generated reference signal in accordance with the fluctuation in the off voltage. An analog-to-digital conversion unit performs the conversion on the basis of the corrected reference signal.

摘要： To prevent a decline in image quality by reducing a fluctuation in an image signal that is based on a fluctuation in a voltage of a negative voltage power source.An image signal output unit is controlled in accordance with a first control signal indicating either voltage state of an on voltage for causing a conductive state and an off voltage having a polarity different from that of the on voltage, and outputs an analog image signal corresponding to the electric charge held by an electric charge holding unit in the conductive state. A reset unit is controlled in accordance with a second control signal indicating either voltage state of the on voltage and the off voltage, resets the electric charge holding unit in the conductive state, transmits a fluctuation in the off voltage to the electric charge holding unit, and fluctuates the analog image signal. A reference signal generation unit generates a reference signal being a signal serving as a reference used when conversion from an analog image signal output from the image signal output unit into a digital image signal is performed. A reference signal correction unit corrects the generated reference signal in accordance with the fluctuation in the off voltage. An analog-to-digital conversion unit performs the conversion on the basis of the corrected reference signal.
