A METHODE OF SPEAKER'S FACE AREA DETECTION IN COMMUNICATION TERMINAL AND THE DISTANCE MEASUREMENT BETWEEN SPEAKER AND COMMUNICATION TERMINAL USING THE SAME AND COMMUNICATION TERMINAL USING THESAME

摘要

PURPOSE: A method for detecting a face area of a speaker in a communication terminal and the communication terminal using the same, and a method for measuring the distance between speakers and a communication terminal using the same are provided to supply an optimized distance for guaranteeing high communication quality to a speaker. CONSTITUTION: A transceiving unit of a communication terminal receives a k-numbered image frame(S210). A converting unit converts the k-numbered image frame into color signal components corresponding to a plurality of color coordinate systems(S230). A probability mask assigning unit distinguishes the color signal components(S240). A detection unit calculates horizontal and vertical histogram values(S270). The detection unit detects a face area using the histogram value(S280).
