Abstract
To reduce power consumption in a solid-state image sensor that detects weak light. The solid-state image sensor includes a photodiode, a resistor, a measuring unit, and a control unit. The photodiode photoelectrically converts incident light and outputs a photocurrent. The resistor drops a potential of one end of the photodiode to a value lower than a power supply potential every time a photocurrent is output. The measuring unit measures illuminance of the incident light on the basis of a frequency of dropping of the potential of one end. The control unit controls the power supply potential to a lower value as the measured illuminance is higher.
