Abstract
A control method applied in an electronic apparatus including a projecting unit and a depth detecting unit is described. The projecting unit is able to project first multimedia data onto a target object. The method includes detecting depth information of the target object by using a depth detecting unit; calculating a second parameter of the projecting unit according to the depth information of the target object and a first parameter of the projecting unit; and moving the projecting unit to a first position based on the second parameter of the projecting unit to make the projecting unit project a first display picture of the first multimedia data. The focusing of the projector can be executed quickly and accurately.
