Abstract
A projection apparatus including a micro-electro-mechanical system (MEMS) mirror module and a control unit is provided. The MEMS mirror module drives an image beam to scan along a first direction and a second direction on an imaging region. The control unit is electrically connected to the MEMS mirror module and outputs a driving signal with a corresponding pulse width according to a projection position of the image beam in the second direction of the imaging region. A projection method is also provided.
