Abstract
In an electronic device, a first sensor detects a detection target on a first region. A second sensor detects a detection target on a second region. A third sensor detects a detection target on a third region. A power control unit turns on the second sensor in a case where the first sensor detects the detection target on the first region. The power control unit turns on the third sensor and turns off the first sensor in a case where the second sensor detects the detection target on the second region.
