US 12,487,655 B2 · Projection apparatus and control method thereof

Abstract

A projection apparatus and a control method thereof are provided. The projection apparatus includes a processor, a sensor, and a projection module. When a command corresponding to a standby mode is received, the processor sets the projection apparatus to a first sub-standby mode. The sensor is enabled to sense whether there is a living object located in a sensing area outside the projection apparatus. The standby mode is maintained as the first sub-standby mode in response to sensing that the living object is not in the sensing area. The standby mode is set to be switched to a second sub-standby mode in response to sensing that the living object is in the sensing area. A maximum power consumption of the first sub-standby mode is less than a maximum power consumption of the second sub-standby mode. In the first and second sub-standby modes, the projection module is not enabled.
