摘要： A projection system and a method for selecting an image capturing number for image blending are provided. Multiple projection devices are driven one-by-one to project a pattern; multiple image capturing devices are driven to capture the pattern projected by each projection device, so as to obtain multiple image capturing results corresponding to the image capturing devices. Finally, at least one of the image capturing devices is selected to serve as an image capturing source for image blending based on the image capturing results. An image capturing range is identified through projected patterns, and an effective range is calculated and then selected for use, which is used for calculations required for automatic blending, so as to avoid a problem of being unable to maintain blending and merging due to environmental influences or failure of the image capturing device when performing image recognition and calculation required for automatic blending and merging.

摘要： The disclosure provides a projection system and a projection operation method. The projection operation method causes the projection device disposed inside the biologically-modeled housing to project the facial image onto the face projection area of the biologically-modeled housing. The face projection area is light-transmissive and curved. The controller identifies the voice signal received by the sound-receiving device. When the controller obtains the identification result, if the projection data stored in the storage device includes the target projection data corresponding to the identification result, the controller controls the projection device to project the facial image according to the target projection data, or, if the projection data stored in the storage device does not include the target projection data, the controller controls the communication device to receive the target projection data from the external device and stores it in the storage device.

摘要： The disclosure provides an illumination system and a projection device applying the illumination system. The illumination system includes a laser light source, a wavelength conversion module, and a spot region modulation module configured to shift a transmission path of a laser beam. When the wavelength conversion module rotates, the spot region modulation module moves, in a first period of time, the laser beam in a wavelength conversion region of the wavelength conversion module along a first shift path, so that the laser beam forms a first spot region in an irradiation region in the wavelength conversion region. The spot region modulation module causes, in a second period of time, the laser beam to form a second spot region in an irradiation region in a non-conversion region of the wavelength conversion module. A size of the first spot region is greater than a size of the second spot region.
