1. A projection device, comprising:

  • an image light generating device, for generating an image light for forming a projected image;

    a pixel shifting device, disposed on a transmission path of the image light generated by the image light generating device, the pixel shifting device being configured to switch its state between a first state and a second state, wherein a first projected image formed after the image light passes through the pixel shifting device when the pixel shifting device is in the first state and a second projected image formed after the image light passes through the pixel shifting device when the pixel shifting device is in the second state are shifted with respect to each other; and

    a control processor, respectively coupled to the image light generating device and the pixel shifting device, wherein the control processor controls the pixel shifting device to perform a switching of state, and during a time interval when the pixel shifting device performs the switching of state, controls the image light generating device to generate no image light.
