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.
