APPARATUS FOR PROCESSING IMAGE DATA TO TRACK LOCATION OF LIGHT SOURCE

摘要

Disclosed is an image processing device which extracts location information relative to a particular light source from image data. According to the present invention, the image processing device comprises: an image sensing module which receives light and converts the light into image data; and a data processing module which repeatedly extracts location information that changes over time relative to the light of a particular frequency or a particular frequency band from the image data received from the image sensing module. Here, according to the present invention, the image processing device minimizes the amount of data to be processed in a device that tracks the location of a light source moving within a space, and thus the computation amount is reduced remarkably whereby the processing speed and complexity of an algorithm are improved.
