Projector and projection method
A projector and a projection method that effectively protect a to-be-protected object existing in a sensing area are provided. The projector includes a first sensor, a second sensor, an optical engine and a processor. The optical engine includes a light source. The first sensor receives a first sensed signal, generates a first signal corresponding to the first sensed signal and transmits the first signal to the processor. The second sensor receives a second sensed signal different from the first sensed signal, generates a second signal corresponding to the second sensed signal and transmits the second signal to the processor. The processor determines whether the first signal and the second signal fall into their respective pre-determined ranges. The processor transmits a light adjusting signal to control a light source.
