Abstract: Video previewing methods for electronic devices with a touch-sensitive display unit for providing preview of a video to be played are provided. First, a resolution of the touch-sensitive display unit of the electronic device is detected. Thereafter, a preview screen is generated on the touch-sensitive display unit according to the resolution of the touch-sensitive display unit, wherein the preview screen includes M level frame bars and each of the M level frame bars displays N video frames, and N for each of the M level frame bars is determined based on the resolution of the touch-sensitive display unit, where M?1 and N?1.

Abstract: Unsymmetrical bisazides containing chelating and non-chelating azido groups undergo chemoselective three-component copper(I)-catalyzed azide-alkyne conjugation reactions with two different alkyne molecules. In conjunction with the reactivity gap between aromatic and aliphatic alkynes, a bistriazole molecule can be generated with an excellent regioselectivity by mixing two alkynes and a bisazide in a single reaction container. This method is applicable in aqueous solutions at neutral pH, which may lend utilities in bioconjugation applications.

The method comprises capturing a pair image, wherein the pair image comprise a first side image and a second side image; separating the first side image and the second side image from the pair image; performing a panorama synthesis process to obtain a first side panorama image and a second side panorama image; performing a 3D synthesis process according to the first side panorama image and the second side panorama image to generate the stereo 3D panorama image; and storing and outputting the stereo 3D panorama image.

Abstract: A stereoscopic image system is provided. The stereoscopic image system comprises: a depth detection unit, for receiving a two-dimensional image and a corresponding depth image, and generating a depth level map according to the two-dimensional image and the corresponding depth image; a stereoscopic image generator, for generating a stereoscopic image pair corresponding to the two-dimensional image according to the two-dimensional image and the depth level map; and a stereoscopic image adjusting apparatus, for generating a depth level range map according to the depth level map, and performing a pixel shifting process and an interpolation process to objects within a plurality of depth levels in the stereoscopic image pair to generate an output stereoscopic image pair according to the stereoscopic image pair and the depth level range map.

Abstract: An image adjustment method is provided in the invention. The image adjustment method has the following steps: receiving at least one first image in front of a display captured by a camera device, wherein the display has a screen center; detecting the first image to generate a facial image, wherein the facial image has a face position and a face center; capturing a second image with the face center from the facial image according to the face position; shifting the second image to overlap the face center with the screen center to generate a third image; and scaling the third image to generate an output image in accordance with a predetermined resolution.

Abstract: A high-voltage, super-voltage and heavy current breaker is formed by combining intelligent optical vacuum breaker modules (21) with phase selection function in series and/or parallel connection. Each vacuum breaker module (21) is connected each other in series after being connected in parallel with a resistance capacitance device or with a resistance capacitance device and a zinc oxide arrester valve plate (22). Tight coupling reactors are connected with several serial branches of the vacuum breaker module (21) simultaneously to achieve parallel connection of several serial branches of the vacuum breaker module (21). The breaker distributes the high-voltage and heavy current into the low voltage and low current serial and parallel vacuum breaker modules (21) to share.

Abstract: A method for recording a monitored image is disclosed. The method includes the following steps. First, a monitored image is captured. A foreground image and a background image are obtained according to the monitored image and a previously monitored image. Brightness information and a threshold value are generated according to the foreground image and the background image respectively. It is determined that whether a moving object has displayed on the monitored image based on the brightness information and the threshold value. If so, the recording of the monitored image starts.
