  • Patent number: 11950009
    Abstract: In a solid-state image sensor that compares an amount of change in light amount and a threshold, time required to adjust the threshold is shortened. The solid-state image sensor includes a voltage comparison unit and a count unit. In the solid-state image sensor, the voltage comparison unit compares an analog signal according to an amount of change in incident light with a predetermined voltage indicating a boundary of a predetermined voltage range, and outputs a comparison result as a voltage comparison result. Furthermore, in the solid-state image sensor, the count unit counts a count value every time the voltage comparison result indicating that the analog signal falls outside the voltage range is output.

    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.
