Proximity object tracker

摘要

Object tracking technology, in which controlling an illumination source is controlled to illuminate while a camera is capturing an image to define an intersection region within the image captured by the camera. The image captured by the camera is analyzed to detect an object within the intersection region. User input is determined based on the object detected within the intersection region and an application is controlled based on the determined user input.

1. An electronic system comprising:
an image sensor having a field of view of a first area; an illumination source that is configured to illuminate a second area, the second area intersecting the first area to define (a) an intersection region illuminated by the illumination source and within the field of view of the image sensor and (b) a non-intersection region not illuminated by the illumination source and within the field of view of the image sensor; and a processing unit configured to perform operations comprising:
receiving an image from the image sensor;analyzing the image to detect an object within the intersection region and exclude objects within the non-intersection region; anddetermining user input based on the object detected within the intersection region, wherein the user input is determined based on a mapped position of the detected object.
