The invention discloses a control method and control device for a laser projection module, a depth camera and an electronic device. The laser projection module includes a laser emitter. The laser emitter includes a plurality of point light sources forming independently controlled light-emitting arrays. The control method includes the steps of turning on a predetermined number of the light-emittingarrays to detect the projection distance between a user and the laser projection module, determining the target number of the light-emitting arrays according to the projection distance, and turning on the point light sources in the target number of the light-emitting arrays. According to the control method, the control device, the depth camera and the electronic device of the embodiment, the point light sources are divided into a plurality of independently controlled light-emitting arrays, when the laser projection module works, firstly the predetermined number of the light-emitting arrays are turned on to detect the projection distance between the user and the laser projection module, and then the target number of the light-emitting arrays are determined according to the projection distance. Therefore, the problem can be avoided that harm is caused to the eyes of the user due to too high emitted laser energy since a large number of the light-emitting arrays are turned on.
