Abstract: The present invention relates to an LED lens, in which a planar bottom has a pair of halves symmetrically connected with each other about a reference line and narrowed in the vicinity of the reference line. A pair of substantially semicircular reflecting surfaces are extended from both edges of the bottom connected with both ends of the reference line. A radiating surface is connected with remaining edges of the bottom and semicircular edges of the reflecting surfaces. The reflecting surfaces reflect light beams are introduced from the LED chip through the bottom toward the radiating surface. The radiating surface radiates the light beams to the outside when the light beams are introduced to the radiating surface through reflection from the reflecting surfaces and directly through the bottom, so that the light beams are radiated to the outside in a predetermined beam angle.

Abstract: The present invention relates to a dipolar LED and a dipolar LED module incorporating the same, in which an upper hemisphere-shaped base houses an LED chip therein and adapted to radiate light from the LED chip to the outside, and a pair of reflecting surfaces placed at opposed top portions of the base in a configuration symmetric about an imaginary vertical plane. The vertical plane passes through the center of the LED chip perpendicularly to a light-emitting surface of the LED chip. The reflecting surfaces are extended upward away from the top portions of the base to reflect light from the LED chip away from the imaginary vertical plane. A pair of radiating surfaces are placed outside the reflecting surfaces, respectively, to radiate light from the reflecting surfaces to the outside. In this way, light emission from the LED chip can be concentrated in both lateral directions.

Abstract: A method of locating a half-pixel resolution motion vector. The method first determines a sum of absolute difference for a predetermined number of neighbors to a current pixel. The gradient of these sums of absolute differences is then calculated. A motion vector is then selected based upon the gradient that indicates which vector lies in a direction of steepest descent. This motion vector is then used in motion compensation for video compression.

Abstract: Disclosed herein is a light emitting diode (LED) device. The light emitting diode device comprises a package formed with a terminal for applying an electrical signal, one or more LED chips mounted on the package such that the LED chips are electrically connected to the terminal, a lens formed to surround the LED chips on the package for changing path of light emitted from the LED chips to the horizontal direction with the difference of the refraction rates of the media, and a reflector formed on the lens for reflecting the light, emitted above the lens without being refracted in the horizontal direction at the lens, to the horizontal direction. The LED device reflects the light, which is deviated from the optical design range of the lens and emitted above the lens, back to the lens, thereby preventing the hot spot from being generated, and enhancing horizontal emission efficiency of the light.

Abstract: A method of determining a quantization parameter for video compression. A block characteristic for blocks in a video frame is quantized and then used to obtain a candidate quantization parameter. With the candidate quantization parameter, a number of bits for the blocks in the video frame is summed, producing a candidate bit rate. If the candidate bit rate is greater than a predetermined bit rate threshold, the candidate quantization parameter is set as the quantization parameter.

Abstract: A method is described for quickly and efficiently transcoding digital video (DV) data to digital versatile disk (DVD) data. The method uses the baseline method for DV to DVD transcoding (i.e., full DV decoding, and DVD encoding), but eliminates the DCT and IDCT functions from the baseline method for I (Intraframe) coded frames; and further combines the inverse quantization (IQ) and inverse discrete cosine transformation (IDCT) functions of DV decoding, and the quantization (Q) and discrete cosine transformation (DCT) functions of DVD encoding into a single quantization function for I/P (Intraframe/Predictive) coded frames and P/P (Predictive/Predictive) coded frames.
