20090213142 | Coding system and method for a bit-plane - A coding system and method for a bit-plane is disclosed. A bit-plane is decomposed or segmented into at least a background area and a foreground area. A number of encoders are provided for efficiently encoding the background area and the foreground area respectively. Accordingly, the performance of compression is substantially improved by this data or texture segmentation. | 08-27-2009 |
20090214128 | Compression system for a bit-plane - A compression system and method for a bit-plane is disclosed. A run-length encoder is used to compress a first block of an image, which includes at least a first line in the image. An offset encoder is used to compress a second block of the image, which includes a number of lines different from the first line. | 08-27-2009 |
20100002131 | FLICKER REDUCTION FOR 2-DIMENSIONAL DE-INTERLACING - A method and apparatus of de-interlacing are disclosed. A flicker bit is assigned to each line of a frame to indicate a flicker characteristic of each line. A de-interlaced line is then generated by duplicating a neighboring scan line in a current frame according to an active flicker bit of a previous frame. | 01-07-2010 |
20110194025 | METHOD AND SYSTEM OF HIERARCHICAL MOTION ESTIMATION - A method and system of hierarchical motion estimation include a reference frame and a current frame being downsampled, and the downsampled reference frame being stored. A coarse motion vector (MV) map is generated according to the downsampled reference frame and the downsampled current frame. Scan lines adjacent to a center scan line corresponding to a downsampled scan line in the downsampled reference frame are retrieved and then stored. A refined MV map is generated according to the coarse MV map, the current frame and the stored scan lines adjacent to the center scan line. | 08-11-2011 |
20110221762 | CONTENT-ADAPTIVE OVERDRIVE SYSTEM AND METHOD FOR A DISPLAY PANEL - A content-adaptive overdrive system and method, for a display panel, include a frame difference device and an overdrive device. The frame difference device generates a frame difference map according to a current frame and a previous frame. The frame difference map includes a number of flags respectively indicating similarity between corresponding pixels or blocks of the current frame and the previous frame. The overdrive device adaptively performs an overdrive function based on the frame difference map, the current frame, the previous frame and an overdrive lookup table, hence resulting in an overdrived frame. | 09-15-2011 |
20110249188 | METHOD OF BLOCK-BASED MOTION ESTIMATION - In a method of block-based motion estimation a motion vector map is obtained by obtaining a motion vector of each macroblock (MB) in the current frame with respect to the reference frame. The motion vector of each MB in an interpolated frame is then determined according to the motion vector map. | 10-13-2011 |
20110249870 | METHOD OF OCCLUSION HANDLING - In a method of occlusion handling, a reference frame and a current frame are first provided, and at least one foreground object is determined. At least a covered region or an uncovered region with respect to the foreground object is determined. The covered region is then interpolated exclusively accordingly to the current frame, or the uncovered region is interpolated exclusively according to the reference frame. | 10-13-2011 |
20110255596 | FRAME RATE UP CONVERSION SYSTEM AND METHOD - The invention is directed to a frame rate up conversion (FRUC) system and method. A motion estimation (ME) unit is configured to generate at least one motion vector (MV) according to a frame input. A triple-line buffer based motion compensation (MC) unit is configured to generate an interpolated frame according to the MV, a reference frame and a current frame, thereby generating a frame output with a frame rate higher than a frame rate of the frame input. | 10-20-2011 |
20120056871 | THREE-DIMENSIONAL IMAGING SYSTEM AND METHOD - A three-dimensional (3D) imaging system and method are disclosed. A motion estimation and motion compensation (MEMC) unit performs the motion estimation (ME) and the motion compensation (MC) on a reference frame and a current frame, thereby generating an MEMC generated frame and motion vector (MV) information. A depth controller partitions the reference frame into multiple regions according to the MV information, thereby generating depth information. A scene-mode depth generator generates a depth map according to the reference frame and the depth information. A depth-image-based rendering (DIBR) unit generates a scene-mode generated frame according to the reference frame and the depth map. | 03-08-2012 |
