摘要: A projection system and control method thereof are provided. A player apparatus generates and transmits an image signal to a projection apparatus, and a plurality of first distance values within a first time are received through a distance sensor. An average value of the plurality of first distance values is calculated and set as a reference value. During a playback of the image signal, an average value of a plurality of second distance values received from the distance sensor is calculated every second time to serve as a first-stage detection value. When the first-stage detection value is less than the reference value, the image signal is paused.

摘要: A projection device and a projection method thereof are provided. The projection device includes a spatial modulator, a first optical actuator, a driving circuit, and a control circuit. The spatial modulator modulates a beam to generate an image beam. The driving circuit is coupled to the first optical actuator, determines a swinging mode of the first optical actuator according to an input video signal, and converts a display frame into sub-display frames corresponding to the swinging mode. The control circuit is coupled to the spatial modulator and the driving circuit, controls the spatial modulator to generate the image beam according to the sub-display frames, and outputs synchronization signals corresponding to the sub-display frames to the driving circuit. The driving circuit drives the first optical actuator to swing according to the synchronization signals and the swinging mode to change an optical path of the image beam to generate a projection image.

摘要: An image projection device includes: a calculation processor which executes a video mute operation on the basis of a video mute manipulation signal for requesting the video mute operation, determines whether or not a screensaver of video output equipment has been activated on the basis of a first signal input from the video output equipment, determines the presence or absence of a second signal to be input from the video output equipment, and determines whether or not information indicating the activation of the screensaver of the video output equipment has been stored. The calculation processor determines to continue the video mute operation when the video mute operation has been requested, when it is determined that there is no second signal, and when it is determined that the information indicating the activation of the screensaver of the video output equipment has been stored.

摘要: A vehicle analysis environment includes one or more display screens, such as a display screen wall or an array of display screens. While a vehicle is in the vehicle analysis environment, a vehicle analysis system renders and displays one or more vehicle sensor calibration targets and/or one or more simulated events on the one or more display screens. Vehicle sensors of the vehicle capture sensor data while in the vehicle analysis environment. The sensor data depict the vehicle sensor calibration targets and/or the simulated events that are displayed on the one or more display screens. The vehicle can output actions based on the simulated event and/or can calibrate its vehicle sensors based on the vehicle sensor calibration targets.

摘要: An image projector includes a spatial light modulator (SLM) with a two dimensional array of pixel elements controllable to modulate a property of light transmitted or reflected by the pixel elements. An illumination arrangement delivers illumination to the SLM. A collimating arrangement collimates illumination from the SLM to generate a collimated image directed to an exit stop. The illumination arrangement is configured to sequentially illuminate regions of the SLM, each corresponding to a multiple pixel elements. A controller synchronously controls the pixel elements and the illumination arrangement so as to project a collimated image with pixel intensities corresponding to a digital image.
