OPTICAL POINTING SYSTEM

摘要

There is provided an optical pointing system including at least one reference beacon, an image sensor, a storage unit and a processing unit. The image sensor is configured to capture an image frame containing a beacon image associated with the at least one reference beacon. The storage unit is configured to save image data of at least one object image in the image frame. The processing unit is configured to sequentially process every pixel of the image frame for identifying the object image and real-timely remove or merge the image data, saved in the storage unit, associated with two object images within a pixel range of the image frame thereby reducing the used memory space.

1. An optical pointing system comprising:
at least one reference beacon; an image sensor configured to capture an image frame containing a beacon image associated with the at least one reference beacon; a storage unit configured to save image data of at least one object image in the image frame; and a processing unit configured to
sequentially process every pixel of the image frame within a scan period for identifying the at least one object image, andwhen a plurality of object images simultaneously appear within a combinable range of the image frame within the scan period, merge image data, saved in the storage unit, associated with the plurality of object images within the combinable range.
