20090278774 | CONTENT-ADAPTIVE ADJUSTMENT SYSTEM AND METHOD - A content-adaptive adjustment system and method for a light-emitting display is disclosed. An analysis unit analyzes, for example, the average data intensity/power consumption and the data distribution of the image data to be displayed. An adjustment unit then adjusts, for example, the pixel values of the image data or the drive levels of the light-emitting display according to the analyzed data distribution, such that the consumed power in the light-emitting display could be considerably reduced. | 11-12-2009 |
20100079362 | Overdrive Compensation/Update Adaptable to Dynamic Gamma Generator - An overdrive system adaptable for a dynamic gamma generator is disclosed. A current gray-to-voltage converter (G/V) converts image data of a current frame from gray code to voltage level, and a previous gray-to-voltage converter (G/V) converts image data of a previous frame from gray code to voltage level. The voltage level of current frame and the voltage level of previous frame are inputted to an overdrive-voltage lookup table to retrieve an overdrive voltage level. Afterwards, a voltage-to-gray converter (V/G) converts the retrieved overdrive voltage level from voltage level back to gray code, resulting in an overdrive gray code. Accordingly, the overdrive gray code is compensated. Alternatively, the overdrive gray code is used to update an overdrive-gray-code lookup table, an output gray code of which is fed to the source driver. | 04-01-2010 |
20100079448 | 3D Depth Generation by Block-based Texel Density Analysis - A system and method of generating three-dimensional (3D) depth information is disclosed. A classification and segmentation unit segments a two-dimensional (2D) image into a number of segments, such that pixels having similar characteristics are classified into the same segment. A spatial-domain texel density analysis unit performs texel density analysis on the 2D image to obtain textual density. A depth assignment unit assigns depth information to the 2D image according to the analyzed textual density. | 04-01-2010 |

20100135585 | Method and Apparatus of Tile-based Belief Propagation - A method and apparatus of tile-based belief propagation are disclosed. An image is split into a number of tiles. Messages are iteratively generated within each of the tiles based on the messages from neighboring pixels to the tile at a previous iteration, wherein each message represents information of a state of the pixel. The generated messages for sending out of the tiles are stored. Labels are then determined based on the stored messages, wherein each label represents the state of the pixel. | 06-03-2010 |
20100146528 | Method of Directing a Viewer's Attention Subliminally in Image Display - A method of directing a viewer's attention in an image display to enhance the perceived image quality and thus the viewer's preference of the image is disclosed. An image with an area of interest (AOI) is provided. The AOI is briefly displayed for a first time period. Subsequently, the image is normally displayed in its entirety for a second time period that is longer than the first time period. As a result, the viewer's attention is involuntarily directed to the AOI in a subliminal manner. | 06-10-2010 |
20100220893 | Method and System of Mono-View Depth Estimation - A method and system of mono-view depth estimation are disclosed. A two-dimensional (2D) image is first segmented into a number of objects. A depth diffusion region (DDR), such as the ground or a floor, is then detected among the objects. The DDR generally includes a horizontal plane. The DDR is assigned the depth, and each object connected to the DDR is assigned depth according to the depth of the DDR at the connected site. | 09-02-2010 |
20100220924 | Method and System of Extracting A Perceptual Feature Set - A method and system of extracting a perceptual feature set for image/video segmentation are disclosed. An input image is converted to obtain a hue component and a saturation component, where the hue component is quantized into a number of quantum values. After weighting the quantized hue component with the saturation component, the weighted quantized hue component and the saturation component are subjected to a statistical operation in order to extract feature vectors. Accordingly, the method and system provide overall segmentation results that are very close to human interpretation. | 09-02-2010 |

The method comprises the following steps: firstly, at least one initial depth map associated with one image of the 3D image pair based on stereo matching technique is received, wherein the one image comprises a plurality of pixels, and the initial depth map carries an initial depth value of each pixel. Then, the inconsistence among the pixels of the one image of the 3D image pair is detected to estimate a reliable map. Finally, the initial depth value is interpolated according to the reliable map and the proximate pixels, so as to generate a revised depth map by revising the initial depth value. | 11-22-2012 |
