Abstract
The time the control device of a small information device spends in an energy conservation mode is maximized to achieve low power consumption while stabilizing measurements. A measurement device that intermittently drives an LED to emit a detection beam and intermittently receives and measures the detection beam by means of a photodetector has a CPU that changes its own operating mode to a sleep mode in which the LED drive state is sustained for the time until the LED drive state stabilizes after driving the LED starts.
