IMAGE PROCESSING APPARATUS AND A METHOD THEREOF CAPABLE OF ACCURATELY REDUCING THE SATURATION OF AN IMAGE BY DESIGNATING AN AUTOMATIC EXPOSURE WEIGHTED VALUE APPLYING AREA ACCORDING TO A SUBJECT LOCATION MEASUREMENT VALUE

摘要

PURPOSE: An image processing apparatus and a method thereof are provided to reduce the saturation of an image by determining a distance to a subject through a plurality of distance measurement sensors and controlling automatic exposure weighted value.;CONSTITUTION: A digital image converter converts an optical image reflected from a subject into image data (S100). In case an infrared ray lighting unit is turned on, a distance measurement unit measures a distance to the subject or the location of the subject through a plurality of the distance measurement sensors (S110,S120). An automatic exposure weighted value control unit sets up an automatic exposure weighted value applying area according to a measurement result and applies the set automatic exposure weighted value to the image data (S130,S140).;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Start; (BB) End; (S100) Receive an optical image and convert into digital image data; (S110) Lamp ON?; (S115) Apply an automatic exposure weighted value as a global variable; (S120) Detect a distance to a subject of the location of the subject; (S130) Set an automatic exposure weighted value area according to the detected distance or location; (S140) Apply the automatic exposure weighted value; (S150) Treated with shading correction; (S160) Treated with gamma correction; (S170) Output
