Object tracking for artificial vision
First Claim
1. A vision enhancement apparatus for a vision-impaired user, comprising an image processor arranged to:
- process high resolution video data representing images of a scene and display the resulting images to the user;
automatically detect and track a user selected object in the images; and
automatically modify the video data, by reserving a user selected area of the displayed images for displaying the tracked object as a separate video tile within the images of the scene to provide modified video data that includes;
the displayed images of the scene that includes the tracked object; and
the separate video tile, at the user selected area within the displayed images, to display the tracked object,wherein the tracked object remains displayed at the separate video tile despite movement of the user or the tracked object.

Abstract
This invention concerns the tracking of objects in video data for artificial vision; for instance for a bionic eye. More particularly, the invention concerns a vision enhancement apparatus for a vision-impaired user. In other aspects, the invention concerns a method for enhancing vision and software to perform the method. The image processor operates to process video data representing images of a scene. Automatically detect and track a user selected object, such as a face, in the images. And, automatically modify the video data, by reserving a user selected area of the displayed images for displaying the tracked object as a separate video tile within the scene. The separate video tile remains in the selected area despite movement of the camera relative to the scene, or movement of the user relative to the object or the scene.
