METHOD FOR AUTOMATICALLY SETTING PARAMETER TO PROCESS INFRARED SIGNAL, AND INFRARED SIGNAL PROCESSING DEVICE AND INFRARED ELECTRONIC BLACKBOARD SYSTEM USING SAME

摘要

The present invention relates to a method for automatically setting a parameter to process infrared signal, and an infrared signal processing device and an infrared electronic blackboard system using the same. The method comprises the steps of: analyzing an infrared signal recognized by an infrared sensor according to a preset infrared brightness threshold value, and detecting size information of the infrared signal; comparing the detected size information of the infrared signal with a reference value; and changing the infrared brightness threshold value based on the comparison result.;COPYRIGHT KIPO 2017
