Patent number: 9984282Abstract: A media editing device obtains a digital image, and a facial region of an individual in the digital image is identified by a facial region analyzer. A plurality of facial features of the facial region is identified by a facial feature identifier. A skin color of the facial region is determined, and eyebrow regions in the facial region are identified based on the facial features. Each of the eyebrow regions is partitioned into a plurality of segments, and a determination is made, for one or more of the segments, whether an area above or an area below the segment has a color matching the skin color. The segment is designated as a verified eyebrow region or as an overlapped region depending on whether the area above or the area below the segment has a color matching the skin color. A special effect is applied on the verified eyebrow region.Type: GrantFiled: December 9, 2016Date of Patent: May 29, 2018Assignee: PERFECT CORP.Inventors: Wei-Ming Chen, Chih-Yu Cheng

Patent number: 8983187Abstract: A system for editing a digital image comprises a low pass filter for receiving a source image and for filtering high spatial frequency components of the source image to generate a smoothed image. An arithmetic operator unit subtracts color values of the smoothed image from color values of the source image to produce a first image value on pixel-by-pixel basis. A gradient reversal analyzer compares gradient values of the smoothed image to gradient values of the source image and generates a control signal. A boost controller generates a new value for each pixel of a boost parameter map according to the control signal. The boost controller applies the boost parameter map to modify the first image value to generate a second image value. The arithmetic operator unit is further configured to generate an edge enhanced image according to color values of the source image and the second image value.Type: GrantFiled: March 7, 2013Date of Patent: March 17, 2015Assignee: Cyberlink Corp.Inventor: Chih-Yu Cheng

Patent number: 8885105Abstract: Local contrast enhancement comprises obtaining a first frame as a reference frame and a second frame as a current frame. The reference frame is partitioned into a plurality of reference regions, and a first color mapping function is derived for at least one of the reference regions in the reference frame according to the corresponding color distribution. The first color mapping function comprises, for at least one of a predetermined set of colors, a first source color value and a first contrast-enhanced color value. The current frame is partitioned into a plurality of regions, and a second color mapping function is derived for at least one of the regions in the current frame according to the first color mapping functions of at least two of the reference regions in the reference frame. The second color mapping function is applied to generate a contrast-enhanced frame.Type: GrantFiled: January 7, 2014Date of Patent: November 11, 2014Assignee: Cyberlink Corp.Inventors: Chih-Yu Cheng, Yu-En Lin
