Abstract: A head mounted display (HMD) and an imaging method thereof are provided. The HMD comprises a beam splitter, a pico projector, an application processor, an eye image sensor, an adjustment apparatus, an application specific integrated circuit (ASIC), and an eyeglass frame. The application processor controls the pico projector to project a beam. The eye image sensor captures an eye image. The ASIC performs a perspective correction on the eye image to generate a frontal eye image. The ASIC obtains a beam location of the beam and obtains a pupil location according to the frontal eye image. The ASIC according to the beam location and the pupil location controls the adjustment apparatus to adjust the beam splitter. The eyeglass frame carries the beam splitter, the pico projector, the application processor, the eye image sensor and the ASIC.
