| Number | Title | Issue Date |
| 7286720 | Image processing apparatus, image input/output apparatus, scaling method and memory control method The present invention relates to an image processing apparatus, an image input/output apparatus, a scaling method and a memory control method, by which input image data is written to an external memory in tiles, the tiles written to the external memory are read, and... | 10/23/2007 |
| 7263511 | Creating user metric patterns including user notification Exemplary embodiments of the present invention include a method for creating a user metric pattern. Such embodiments typically include receiving, within the network, a plurality of disparate user metrics, determining that the plurality of disparate user metrics rece... | 08/28/2007 |
| 6954502 | Method for encoding and decoding video information, a motion compensated video encoder and a corresponding decoder A method for encoding video information is presented, where a piece of current video information is segmented into macroblocks and a certain number of available macroblock segmentations for segmenting a macroblock into blocks is defined. Furthermore, for each availa... | 10/11/2005 |
| 6947060 | Image forming apparatus, electron beam apparatus, modulation circuit, and image-forming apparatus driving method An image forming apparatus which performs pulsewidth modulation with a pulsewidth set by counting a clock. Especially, for grayscale level correction by setting the frequency of the clock, the periodic clock is counted, and an output pattern is changed in accordance... | 09/20/2005 |
| 6925122 | Method for video-based nose location tracking and hands-free computer input devices based thereon A method for tracking the location of the tip of the nose with a video camera, and a hands-free computer input device based thereon have been described. According to this invention, a convex shape such as the shape of the tip of the nose, is a robust object suitable... | 08/02/2005 |
| 6915019 | Method for combining vector-quantization decoding with color transform or halftoning or both A method of decompressing image data, includes reception of a VQ encoded image. The received image is decoded. Output image color space processing is performed in combination with the decoding as one process. Output image color space processing may include color tra... | 07/05/2005 |
| 6912255 | Bit rate control through selective modification of DCT coefficients An encoder including a DCT transformator for receiving an image or video frame and performing DCT transformation upon a pixel block in a macroblock of the frame, thereby providing a matrix of DCT coefficients, a zig-zag matrix-to-vector converter for receiving the m... | 06/28/2005 |
| 6219382 | Method and apparatus for locating a caption-added frame in a moving picture signal Every frame represented by a moving picture signal is divided into blocks. Calculation is made as to a number of pixels forming portions of a caption in each of the blocks. The calculated number of pixels is compared with a threshold value. When the calcu... | 04/17/2001 |
| 5649030 | Vector quantization Improved method and apparatus for vector quantization (VQ) to build a codebook for the compression of data. The codebook or "tree" is initialized by establishing N initial nodes and creating the remainder of the codebook as a binary codebook. Children ent... | 07/15/1997 |
| 5583888 | Vector quantization of a time sequential signal by quantizing an error between subframe and interpolated feature vectors For quantization of subframe feature vectors representative of subframes identified by subframe indexes in each frame of a time sequential signal, such as an audio or a video signal, a first feature vector of a first subframe of a current frame is extract... | 12/10/1996 |
| 5467134 | Method and system for compressing video data A method for compressing video movie data to a specified target size using intraframe and interframe compression schemes. In intraframe compression, a frame of the movie is compressed by comparing adjacent pixels within the same frame. In contrast, interf... | 11/14/1995 |
| 4965580 | Quantizer and inverse-quantizer In a quantizer of the invention, a quantization distortion in the case where the optimum vector code word was used and a quantization distortion in the case where the optimum predictive error vector code word was used, are compared by comparing means, the... | 10/23/1990 |
| 4797739 | Method of compressing and reconstructing image signals by vector quantization A method of compressing and reconstructing image signals by vector quantization comprises the steps of dividing two-dimensional image signals into blocks each comprising a fixed number of samples, selecting a vector that corresponds with the minimum disto... | 01/10/1989 |
