Abstract: A transparency adjustment method adapted to a target object image shown in a video comprising: extracting a first frame from the video and then extracting a second frame from the video, wherein the target object image is not in the first frame and is in the second frame; selecting a target block from the second frame, wherein the target block contains the target object image; obtaining a position of the target block in the second frame and selecting a background block from the first frame according to the position; replacing the target block with the background block to generate a third frame, wherein the third frame comprises the background block and a part of the second frame other than the target block; and generating an output frame according to the third frame, a transparency parameter, and one of the second frame and the target block.

Abstract: An image-capturing device includes a camera module and a controller. The camera module captures an image of an object. The camera module includes a first camera and a second camera. The first camera has a first field of view (FOV) and captures an image in the first FOV, so as to produce a first image. The second camera is adjacent to the first camera and has a second FOV, in which the first FOV is wider than the second FOV. The second camera captures an image in the second FOV, so as to produce a second image. A displayer displays one of the first and second images. When a zoom ratio of the first image increases, the controller selects a display region in the first image according to an object distance, such that the display region is enlarged and then displayed on the displayer.

Abstract: A presentation system includes a video supply device and a video receiver device. A presentation method is used with the presentation system and a network. The video supply device provides an image including an identification label corresponding to the video receiver device. At first, the video receiver device issues a sensing signal in response to a user's operating action on the video receiver device. After the video supply device receives the sensing signal through the network, the identification label in the image is displayed in a dynamic manner.

Abstract: This invention presented a universal de-interlacing method and system by the motion detection, the motion adaptive interpolation, the directional edge interpolation, the 3:2 pull-downed detection and the 3:2 Pull-Downed recovery. Four-field motion detection can detect the motion area and the still area. By cooperating with the motion adaptive interpolation and the directional edge interpolation the picture possesses the very clear quality, high contrast, and high resolution. The 3:2 pull-downed detection and the 3:2 Pull-Downed recovery can detect the 3:2 Pull-Downed movie sequence and recover the interlaced fields into a progressive frames universally without too much overhead of computational power.
