Abstract
A method for selecting portions of images from a video stream including a representation of a subject, the method including the steps of determining a first portion of an image including the subject, determining a target zoom factor among a plurality of zoom factors from the limits determined, a current zoom factor and at least one maximum image resolution and determining target coordinates of the first portion of an image reframed according to the target zoom factor determined and a maximum image resolution.
Claims11
A method for selecting portions of images to be reproduced, from a video stream comprising a plurality of images each comprising a representation of a subject, the method comprising the steps of:
- determining limits of a first portion of an image comprising the subject,
- determining a target zoom factor among a plurality of zoom factors from the limits, a current zoom factor and at least one maximum resolution of the images,
- determining target coordinates of a second portion of an image, representing the subject, obtained from the first portion of an image, by a reframing implemented according to the target zoom factor determined and from the at least one maximum resolution.
(canceled)
A system for selecting portions of images comprising an interface for receiving a video stream comprising a plurality of images each comprising a representation of a subject, and electronic circuits configured for:
- determining limits of a first portion of an image comprising the subject,
- determining a target zoom factor among a plurality of zoom factors from the limits, a current zoom factor and at least one maximum image resolution,
- determining target coordinates of the first portion of an image reframed implemented according to the target zoom factor determined and the at least one maximum image resolution.
