Electronic apparatus and controlling method

A control method for an electronic apparatus including a detection sensor which detects motion of a waving action coming from an object present within a detection range defined by a predetermined detection angle of view and a detection distance, and outputs a detection signal, the control method comprising:

• a step of causing a first driver to output first detection information based on a detection signal corresponding to a first field of view angle detection signals output from the detection sensor;
• a step of causing a second driver to set, in the first driver, a second field of view angle different from the first field of view angle;
• acquire, from the first driver, second detection information based on a detection signal corresponding to the second field of view angle;
• and output the second detection information;
• and
• a step of causing a controller, which includes the first and second drivers, to:
• in response to receiving a first signal from a processor indicating that an operating system is in a first operating state, output the first detection information to the processor, and
• in response to receiving a second signal from the processor indicating that the operating system is in a second operating state with limited operating capabilities compared to the first operating state, output the second detection information to the processor, wherein
• the second field of view angle is narrower than the first field of view angle.
