SYSTEMS, DEVICES AND METHODS FOR TRACKING OBJECTS ON A DISPLAY

摘要

Systems, devices and methods for improved tracking with an electronic device are disclosed. The disclosures employ advanced exposure compensation and/or stabilization techniques. The tracking features may therefore be used in an electronic device to improve tracking performance under dramatically changing lighting conditions and/or when exposed to destabilizing influences, such as jitter. Historical data related to the lighting conditions and/or to the movement of a region of interest containing the tracked object are advantageously employed to improve the tracking system under such conditions.

主权项

1. A method of tracking an object with an electronic device, the method comprising:
defining a reference value based on an average light intensity of pixels in a region of an image frame comprising the object; determining an average light intensity of pixels in the region of a current image frame comprising the object; calculating a difference between the reference value and the determined average light intensity for the region in the current image frame; adjusting the intensity of pixels in the current image frame when the difference is greater than an intensity limit; applying a gain filter to the current image frame; and tracking the object using the pixels in the current image frame.
