An image pickup section 10 includes a sensor section 15 which picks up an image of an object, a control register section 12 which controls the sensor section 15, a nonvolatile memory 13 which stores setup data to be set in the control register section 12, a control signal interface section 11 which sets the setup data stored in the nonvolatile memory 13 in the control register section 12, and an initialization check register 24 which detects an abnormality of the control register section 12. When an abnormality is sensed by the initialization check register 24, the control signal interface section 11 reads out setup data from the nonvolatile memory 13 and performs control so as to reset the setup data in the control register section 12.
