  • Publication number: 20210019867
    Abstract: An image display system includes a body, a first correction unit, and a second correction unit. The body houses a display unit to display an image and projects a virtual image, corresponding to the image, onto a target space using outgoing light of the display unit. The first correction unit corrects for distortion of the image. The second correction unit corrects a display location of the image on the display unit in accordance with an orientation signal representing a change in orientation of the body. Each of divisional areas of a display screen of the display unit is assigned with a distortion correction parameter for correcting for the distortion of the virtual image. The first correction unit applies distortion correction to each of the image regions of the image on the display screen based on a distortion correction parameter assigned to a divisional area where the image region is displayed.

  • Patent number: 9854967
    Abstract: A detector detects head postures and gaze directions from images of a person to be measured captured by an imaging unit; a generation unit generates a gaze direction distribution with respect to each of the head postures, from the head postures and the gaze directions detected by the detector; a calibration unit determines predetermined one of the head postures as a reference posture, and calculates calibration parameters to be used to calibrate the gaze direction distribution with respect to the reference posture; and a correction unit corrects the gaze direction distributions with respect to the head postures other than the reference posture by using the calibration parameters calculated by the calibration unit. This reduces the influence on the calibration which may vary due to change in the head posture.
