ABSTRACT:
A head-mounted image display device with a good operability and a data processing apparatus including such a display device. A head-mounted image display device wherein a liquid crystal panel and an enlarging optical system are crystal display panel through the enlarging optical system housed in a frame and wherein images generated on the liquid are visible in the field of view in front of the frame comprises a first direction detection means (107) disposed in part of the frame (101) for detecting the direction of the user's head; an observation point detection means (109) disposed in part of the frame for detecting the user's line of sight; a trigger input means (4) for transmitting trigger signals; and an image generation means (3, 105) for controlling images generated on the liquid crystal display panel based on signals from the first direction detection, observation point detection, and trigger input means.
