PROJECTION APPARATUS AND PROJECTION METHOD |
| 摘要 |
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. |

1. A projection apparatus, comprising:
a micro-electro-mechanical system (MEMS) mirror module configured to drive an image beam to scan along a first direction and a second direction on an imaging region; and a control unit electrically connected to the MEMS mirror module and configured to output 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, wherein the driving signal is configured to control the MEMS mirror module to drive a scan opening angle of the image beam along the first direction of the imaging region. |
