A projection device having an information input unit, a storage unit, a scaling unit, an image processing unit and a projection unit is provided. The information input unit receives the image file corresponded to a compressed personalized startup image file. The storage unit has a first storage block storing a preset startup image file and a second storage block. The scaling unit generates a projected image signal according to the compressed personalized startup image file, and the scaling unit stores the compressed personalized startup image file in the at least one second storage block. The image processing unit generates a projection control signal according to the projected image signal. The projection unit generates an image beam according to the projection control signal, and projects the image beam on a projection surface to form the startup image screen. The disclosure further provides a personalized startup image setting method.

Projection device and personalized image setting method thereof

The disclosure provides an intelligent voice system and a method for controlling a projector. The system includes a voice assistant, a cloud service platform, a projector, and a management server. When the voice assistant receives a voice signal for controlling the projector, the voice assistant extracts keywords from the voice signal and transmits the keywords to the cloud service platform, wherein the keywords include an alias corresponding to the projector and a first control command, and the cloud service platform includes second control commands. The cloud service platform analyzes the first control command, retrieves the corresponding second control command according to the first control command, and transmits the alias of the projector and the corresponding second control command to the management server. The management server accesses/controls the projector in response to the alias and adjusts the projector as a first operating state according to the corresponding second control command.

Intelligent voice system and method for controlling projector by using the intelligent voice system

A projector and a method for projecting an image light beam according to an image signal are provided. The method includes: receiving the image signal; decoding the image signal to obtain a metadata of the image signal; determining whether the image signal is a HLG-HDR signal according to the metadata; converting a color space of the image signal from a wider color gamut to a narrower color gamut in response to the image signal is the HLG-HDR signal so as to generate a converted image signal; performing a gamma correction on the converted image signal according to the metadata to generate a corrected image signal; transferring the corrected image signal into an optical signal; providing a light beam; respectively modulating the light beam and a illumination beam according to the optical signal to form an image light beam; and projecting the image light beam.

Projector and method for projecting image light beam

The disclosure provides an intelligent voice system and a method for controlling a projector. The system includes a voice assistant, a cloud service platform, a projector, and a management server. When the voice assistant receives a voice signal for controlling a video platform interface, the voice assistant extracts keywords from the voice signal and forwards the keywords to the cloud service platform, wherein the keywords include an alias corresponding to the projector and a first interface control command. The cloud service platform analyzes the first interface control command, acquires the corresponding second interface control command according to the first interface control command, and transmits the alias of the projector and the corresponding second interface control command to the management server. The management server accesses the projector in response to the alias and adjusts a projection situation of the video platform interface projected by the projector.
