Abstract
An image shifting module for shifting imaging positions of sub-images projected on a screen in each frame, and an optical projection device using the same are provided. The image shifting module includes a first vibration mechanism and a second vibration mechanism. The first vibration mechanism is disposed on the transmission path of the sub-images and shifts the sub-images projected on the screen by a first distance along a horizontal direction in each frame time. Moreover, the second vibration mechanism is disposed on the transmission path of the sub-images and shifts the sub-images projected on the screen by a second distance along a vertical direction in each frame time. Through this image shifting module, the image resolution can be increased.
