CPC H04N 23/959 (2023.01) [H04N 5/77 (2013.01); H04N 13/332 (2018.05)] | 18 Claims |
1. A head-mounted device comprising:
at least one sensor system for detecting translation and rotation of the head-mounted device; and
an image sensor for recording images;
the head-mounted device being configured to automatically calibrate parameters under which the image sensor operates when a detected translation remains below a predetermined translational threshold and a detected rotation remains below a predetermined rotational threshold for at least a predetermined period of time;
wherein the predetermined length of time is at least 1.0 s, wherein the predetermined translational threshold is at most 5.0 cm, wherein the predetermined rotational threshold is at most 10.0°, and wherein the automatic calibration is performed based on the scene recorded by the image sensor;
wherein the head-mounted device is configured not to perform the subsequent calibration until translation and/or rotation of the head-mounted device is detected by the sensor system that exceeds at least a predetermined movement threshold, the predetermined movement threshold being at least two times higher than the predetermined translational threshold and rotational threshold.
