The disclosure provides a method and a projection device for focal length calibration. The projection device includes a distance sensor, a projection lens, and a controller. The method includes: defining, by the distance sensor, a detection area on a projection surface; dividing, by the controller, the detection area into a plurality of reference areas; detecting, by the distance sensor, a reference distance between the projection device and each reference area; finding, by the controller, at least one first area and at least one second area in the reference areas; and performing, by the controller, a focusing operation of the projection lens only based on the reference distance of each second area.

Focal length calibration method and projection device

An optical projection system includes a light source module, an optical engine, a thermoelectric generator, a storage unit, a plurality of electronic devices, and a selection unit. The light source module is capable of emitting at least one light beam, and the optical engine receives the light beam and modulates the light beam according to at least one image signal to form an image beam. The thermoelectric generator absorbs heat in the optical projection system and converts the heat into electrical energy, and the storage unit stores the electrical energy. The electronic devices receive the electrical energy stored in the storage unit and have at least two different threshold voltages. The selection unit selectively turns on at least one of electronic devices according to a state of charge of the storage unit.

Optical projection system and energy control method therefor using selection unit

A projection apparatus is provided, which includes a projector body, a first ultrasonic sensor and a second ultrasonic sensor. The projection apparatus is configured to project an image onto a screen. The first ultrasonic sensor and the second ultrasonic sensor are disposed on the projector body. The first ultrasonic sensor and the second ultrasonic sensor are respectively configured to measure a distance between the projector body and the screen. The projector body corrects the image in a horizontal direction through the first ultrasonic sensor and the second ultrasonic according to the measured distances. The first ultrasonic sensor and the second ultrasonic sensor are disposed on a first reference line corresponding to the first direction. The projection apparatus of the invention may provide good image quality.

Projection apparatus

A rotation speed detecting device is provided. The rotation speed detecting device is electrically connected to a motor of a color wheel, and includes a phase detecting unit and a time calculating unit. The phase detecting unit is suitable for detecting a reference phase point of a rotation information outputted by the motor, and outputting a phase signal according to the reference phase point. The time calculating unit is electrically connected to the phase detecting unit, and calculates a speed information of the motor according to the phase signal. In this way, the rotation speed of the motor of the color wheel is correctly measured.
