Abstract
A method for adjusting a projection device and a projection system are provided. A projection device is driven to project an image on a projection target. An image-capturing device is driven to perform image capturing toward the projection target to obtain a captured image. The captured image includes a target object corresponding to the image. A projection position of the target object in the captured image is calculated based on the target object and the captured image. An output power of an illumination light source module of the projection device is adjusted based on the projection position and an ambient luminance.
Claims16
A method for adjusting a projection system comprising:
- driving a projection device to project an image on a projection target;
- driving an image-capturing device to perform image capturing toward the projection target to obtain a captured image, wherein the captured image comprises a target object corresponding to the image;
- calculating a projection position of the target object in the captured image based on the target object and the captured image;
- and
- adjusting an output power of an illumination light source module of the projection device based on the projection position and an ambient luminance.
A projection system comprising:
- a projection device, comprising an illumination light source module, and used for projection on a projection target;
- an image-capturing device, used for performing image capturing toward the projection target;
- and
- a processing unit, coupled to the projection device and the image-capturing device, and configured to:
- drive the projection device to project an image on the projection target;
- drive the image-capturing device to perform image capturing toward the projection target to obtain a captured image, wherein the captured image comprises a target object corresponding to the image;
- calculate a projection position of the target object in the captured image based on the target object and the captured image;
- and
- adjust an output power of the illumination light source module of the projection device based on the projection position and an ambient luminance.
