The invention relates to a projection system and an operation method thereof. The projection system includes multiple projection devices and a central control platform. The central control platform is coupled to the projection devices. The central control platform delivers a data signal and a selection signal to the projection devices. The projection devices generate a decoding result according to the selection signal. At least one projection device is selected from the projection devices to receive the data signal according to the decoding result. The at least one projection device selected from the projection devices generates a projection image corresponding to the data signal. In the invention, one or more projection devices are selected as selected projection devices through signal features of the selection signal, thereby realizing a one-to-many communication mechanism for controlling the projection devices.

Projection system and operation method thereof

The disclosure relates to a projection system and an operation method thereof. The projection system includes a central control platform and a projection apparatus. The central control platform generates a sequence signal according to a self-defined setting. The projection apparatus is coupled to the central control platform and includes a power circuit, a first processing circuit, and an optical engine module. The power circuit passes the sequence signal through an energy storage element to generate a power supply. The first processing circuit performs an operation based on the power supply to generate a decoding result according to the sequence signal. The optical engine module obtains image information according to the decoding result and generates a display image according to the image information.

A projector and a brightness adjusting method are provided. The projector includes a distance sensor configured to detect a distance between the projector and a projection plane, a light source configured to provide an illumination beam, a brightness controlling circuit configured to control the light source, and a processor coupled to the distance sensor, the light source, and the brightness controlling circuit. The processor calculates according to the distance to obtain an image size of a projected image on the projection plane. The processor obtains a current value corresponding to the image size according to a color table. The processor instructs the light source to adjust a luminous flux of the illumination beam according to the current value for generating a target brightness value of the projected image. When a brightness of the projected image is excessively large, a brightness of an image beam of the projector is automatically reduced.

Projector and brightness adjusting method

The invention provides a projection apparatus configured to be disposed on a vehicle door, and a control method of the projection apparatus. The projection apparatus includes an illumination source, a projection display apparatus and a controller. The illumination source is configured to provide an illumination beam. The projection display apparatus is disposed on a transmission path of the illumination beam, and is configured to convert the illumination beam into a projection beam. The controller is coupled to the projection display apparatus. The controller determines whether the vehicle door is a first vehicle door or a second vehicle door according to an opening operation of the vehicle door, and correspondingly causes the projection beam to display an image.

Projection apparatus and control method

A projection apparatus including a housing, a light-transmissive cover, an optical engine module, a frame, and a projection apparatus and media player circuit module is provided. The light-transmissive cover is arranged on the housing to cover an opening of the housing. The optical engine module is configured to provide a projection light beam to be transmitted through the light-transmissive cover. The optical engine module is arranged in the housing. The frame is arranged on a top surface of the optical engine module. The frame includes extension arms extending in a direction away from the top surface. The projection apparatus and media player circuit module is configured to drive the optical engine module, and to play a pattern or an image, and is arranged on the extension arms to be distributed on at least two of side surfaces and a bottom surface of the optical engine module.

Projection apparatus with U-shaped printed circuit board

A pico projector and a control method of the pico projector are provided. The pico projector is installed on a door of a vehicle and includes a light source, a DMD, a projection lens, a power supply unit, and a processing circuit. The processing circuit receives a shutdown warning signal, transmits a parking signal to the DMD to perform a parking operation on the DMD, and notifies the power supply unit of cutting off a first power provided to the DMD after a predetermined time interval from transmitting the parking signal.

Pico projector and control method therefor

A projection device adapted to be placed on a vehicle and a control method of the projection device are provided. The projection device includes a storage device storing image data of at least one projection image, a projection module, a distance detection device measuring a projection distance from the distance detection device to a projection plane, and a control device electrically connected to the storage device, the projection module, and the distance detection device. The control device enables the projection module to project the projection image and controls brightness or size of the projection image according to the corresponding projection distance. The projection device is activated by opening a door of the vehicle, and power of the projection device comes from the vehicle. The projection image can be adjusted according to the projection distance to maintain stable brightness and the size of the projection image.

Projection device and control method thereof

A projector and a brightness adjusting method are provided. The projector includes a distance sensor configured to detect a distance between the projector and a projection plane, a light source, a brightness controlling circuit, and a processor. The light source is configured to provide an illumination beam. The brightness controlling circuit is configured to control the light source. The processor calculates according to the distance to obtain an image size of a projected image on the projection plane and instructs the light source to adjust a luminous flux of the illumination beam according to the image size of the projected image for generating a target brightness value of the projected image. Here, the brightness of the projector is adjusted and maintained to allow users to comfortably watch images with proper brightness.
