20210321075 | 3D CMOS Image Sensor and Imaging Device Design, Process, and Method - A 3D image sensor based on standard Complementary Metal Oxide Semiconductor (CMOS) process is described. The conventional CMOS image sensor measures a 2D projection of the 3D world in gray-scale or color image; this new sensor can measure the third dimension on the 2D image—the depth of object on the 2D image pixels. Since the standard CMOS image sensor can only sense intensity (the number of photons) at each CMOS pixel, this new sensor creates a new mechanism to encode the depth information into an intensity distribution change that CMOS sensor can sense. The idea is based on the observation or lens imaging theory that light cone for any point (pixel) on the image plane is narrower for a near object and wider for a distant object. We then use diffraction to measure the change of incident angle, based on the theory that an oblique light goes through a finite grating producing diffraction patterns multiple times from near field to far field, the incident angle is reflected as diffraction pattern shift. We use a normal CMOS patterning process to create gratings on top of photosensitive material, and place multiple pixels at a certain distance from the gratings to sense the intensity distribution change or shift for different light cones. Then the depth can be calculated by solving the imaging inverse problem. The solution or intermedium solution of such an inverse problem can be pre-calculated or pre-calibrated and placed in lookup tables so that the image sensor can output directly depth information from the 3D CMOS image sensor. | 2021-10-14 |

20210321142 | No-Reference Banding Artefact Predictor - A method of measuring a banding artefact in an image includes generating a gradient profile from the image, where the gradient profile includes respective gradient magnitudes of pixels of the image; generating, using the gradient profile, a candidate banding pixel (CBP) map, where each location of the CBP map is such that a gradient magnitude of the gradient profile of a corresponding pixel of the image being greater than a first threshold and smaller than a second threshold; generating, using the CBP map, a banding edge map (BEM), where the BEM includes connected banding edges of the image; generating, using the BEM, a banding visibility map (BVM), where the BVM includes a respective banding metric for at least some pixels of the image; and generating a banding index of the image using the BVM. | 2021-10-14 |
20210321143 | Sample Adaptive Offset (SAO) Parameter Signaling - Techniques for signaling of sample adaptive offset (SAO) information that may reduce the coding rate for signaling such information in the compressed bit stream are provided. More specifically, techniques are provided that allow SAO information common to two or more of the color components to be signaled using one or more syntax elements (flags or indicators) representative of the common information. These techniques reduce the need to signal SAO information separately for each color component. | 2021-10-14 |
20210321144 | Television with Interactive Portal and System and Method for Use of Same - A television with an interactive portal and system and method for use of the same are disclosed.
