Method of controlling brightness of user-selected area for image desplay device |
摘要 |
A method of controlling brightness of a user-selected area on a monitor screen is disclosed. First, a starting point of a topmost line of a displayed image is determined as a new reference point. Then a line pattern being included in one of image lines of the displayed image is detected. The pattern includes an indicator whose ends are horizontally aligned with vertical edges of the user-selected area. Next, horizontal distances of the vertical edges with respect to the reference point, and a highlight area is identified using the measured horizontal distances. Finally, a brightness gain of the identified highlight area is amplified.
