发明名称 Image display apparatus and method for controlling image display apparatus
摘要 An image display apparatus includes a light source unit, a scanning mirror unit that reflects and raster scans a light beam from the light source unit, a light source drive unit that drives the light source unit based on input image data, a microlens array that is arranged on an optical path between the light source unit and an eye of a user, and an optical sensor configured to detect the presence or absence of the microlens array. When the optical sensor fails to detect the presence of the microlens array, drive of the optical source is stopped.

主权项 1. An image display apparatus, comprising: a light source unit configured to output a light beam; a light source drive unit configured to drive the light source unit based on input image data; a scanning mirror unit configured to reflect the light beam from the light source unit so as to raster scan the light beam by being driven in a main scanning direction and a sub-scanning direction; an exit pupil enlarger that is arranged on an optical path of the light beam output from the light source unit; a detector configured to detect whether the exit pupil enlarger is present on the optical path, and a shutter configured to enter and leave the optical path in accordance with a detection result of the exit pupil enlarger by the detector.
