  • Patent number: 9984282
    Abstract: 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.

  • Patent number: 9429617
    Abstract: A testing apparatus for flip chip LEDs includes a transparent substrate, a spacing member, a flexible transparent carrier, and a vacuum generator. The spacing member is configured on a first surface of the transparent substrate. The flexible transparent carrier is removably assembled to the spacing member so that a closed space is formed by the flexible transparent carrier, the spacing member, and the first surface of the transparent substrate. The vacuum generator is connected to the closed space for pumping air out of the closed space, and then a part of the transparent substrate clings to the first surface to form a testing area for loading the flip chip LED.

  • Patent number: 8983187
    Abstract: 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.

  • Patent number: 8885105
    Abstract: 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.

  • Patent number: 8073203
    Abstract: A system and a method for generating effects in a webcam application are provided. The method includes identifying a first object and a second object in a video image. The method also includes adding a first user-created object to the video image to create an altered video image and adding a second user-created object to the altered video image to further alter the altered video image. Other steps included are associating the second user-created object with the second object; identifying a movement of the second object; and moving the second user-created object in the altered video image in accordance with the association of the second user-created object with the second object. The first object is a static object, and the first user-created object is manually movable. The movement of the second user-created object in association with the second object is independent of a movement of the first user-created object.
