A computer-implemented method for optical image stabilisation and wearable article providing optical image stabilisation

A method of optical image stabilisation comprising: receiving tilt data from a wearable article comprising an image sensor and a lens, generating data for moving the lens a distance based on the change in tilt in order to stabilise a region of interest (ROI) in the image, and adjusting the scaling o...

Beschreibung
Zusammenfassung:	A method of optical image stabilisation comprising: receiving tilt data from a wearable article comprising an image sensor and a lens, generating data for moving the lens a distance based on the change in tilt in order to stabilise a region of interest (ROI) in the image, and adjusting the scaling of the distance to the change in tilt. The ROI may be determined based on user selection, eye-tracking, or object tracking. The scaling may be adjusted based on the distance from the ROI to the center of the image, or based on the distance from a detected object to the lens. A sequence of images may be captured and the method applied to stabilise a different ROI in each image. The wearable article may be a pair of augmented reality glasses and may comprise a gyroscope for generating the rotation data.
