An image processing apparatus includes a print section configured to perform printing on a recording medium, a first detector configured to detect a moving object within a first detection range, a second detector configured to detect the moving object within a second detection range, and a controller configured to switch between a normal mode in which printing by the print section is enabled and a power-saving mode in which printing by the print section is disabled. The controller returns to the normal mode when, after the controller enters the power-saving mode, in response to detection of the moving object by the first detector or the second detector, the first detector or the second detector detects the moving object for a first predetermined period of time or more, and the first detector and the second detector detect the moving object for a second predetermined period of time or more.
