  • Patent number: 11335300
    Abstract: 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.

  • Patent number: 11323668
    Abstract: A projection device and a controlling method of the projection device are provided. The projection device includes a light emitting module, a driver, a light valve, a projection lens and a processor. The light emitting module generates a light beam according to a driving current respectively. The driver generates the driving current and transmit the driving current to the light emitting module according to an operating signal. The light valve receives the light beam to form an image light beam. The projection lens projects the image light beam. The processor provides the operating signal with a default period to the driver and provides an operation of the light valve. According to the operating signal or the operation of the light valve, the driver generates the driving current lower than a default current during a first time interval in the default period.
