The invention discloses a control method and apparatus and an electronic device. The method comprises the steps of monitoring an operation body gesture of a projection area of a projection module when the projection module of the electronic device is in a turn-on state; and when the operation body gesture does not occur in the projection area in a first preset time length, enabling the projection module to be kept in the turn-on state, and controlling a light source of the projection module to be switched to be in a second power consumption mode from a first power consumption mode, wherein a first power consumption value of the light source in the first power consumption mode is higher than a second power consumption value of the light source in the second power consumption mode. According to the control method and apparatus and the electronic device, the projection module does not need to be turned off and the power consumption mode of the projection light source of the projection module is switched; the main power consumption of the electronic device in a projection mode is from the projection light source, so that the power consumption of the projection module and even the electronic device can be reduced on the premise of avoiding frequent turn-off and turn-on of the projection module; and therefore, the purpose of the invention is achieved.
Description
technical field [0001] The present invention relates to the technical field of terminal control, in particular to a control method, device and electronic equipment. Background technique [0002] With the development of electronic technology, the projection function on terminals such as mobile phones is more and more widely used. [0003] Taking the digital light processing projection on the terminal as an example, in this kind of projection, the power consumption of the projection is relatively large due to the need to use a light source. [0004] However, since it takes a long time to start and initialize the projection function, frequently turning off and starting the projection will only bring more power consumption, and cannot reduce the power consumption of the projection. Contents of the invention [0005] In view of this, the present invention provides a control method, device and electronic equipment to solve the technical problem that the projection power consump...
