TRANSITION AREA DETECTION METHOD AND IMAGE PROCESSING APPARATUS USING THE SAME

摘要

An image processing apparatus according to the present invention includes: a line representative value calculating unit which calculates the one-way line representative value of an image including a transition area which is positioned in an image non-display area, in an image display area, and between the image non-display area and the image display area; and a transition area detecting unit which detects the transition area by calculating the first and second change rates of a line representative value and calculating the threshold value of the transition area by using the representative value of the first and second change rates of a first line group and the representative value of the first and second change rates of a second line group which respectively includes multiple lines in a window including multiple lines. [Reference numerals] (AA) Start;(BB) End;(S100a) Detect a first area by calculating the one-way line representative value of an image;(S200a) Detect a second area by calculating the first change rate of a line representative value from the line representative value;(S300a) Detect a transition area by aligning the first area and the second area and performing a logical calculation
