Abstract: Object-based intra-prediction encoding may include generating, by a processor in response to instructions stored on a non-transitory computer readable medium, an encoded block of a current frame of a video stream by encoding a current block from the current frame, including the encoded block in an output bitstream, and outputting or storing the output bitstream. Encoding the current block may include identifying a first spatial portion of the current block, wherein the first spatial portion includes a first pixel from the current block and omits a second pixel from the current block, encoding the first pixel using a first intra-prediction mode, and encoding the second pixel using a second intra-prediction mode, wherein the second intra-prediction mode differs from the first intra-prediction mode.

Abstract: Using the same image sensor to capture both a two-dimensional (2D) image of a three-dimensional (3D) object and 3D depth measurements for the object. A laser point-scans the surface of the object with light spots, which are detected by a pixel array in the image sensor to generate the 3D depth profile of the object using triangulation. Each row of pixels in the pixel array forms an epipolar line of the corresponding laser scan line. Timestamping provides a correspondence between the pixel location of a captured light spot and the respective scan angle of the laser to remove any ambiguity in triangulation. An Analog-to-Digital Converter (ADC) in the image sensor generates a multi-bit output in the 2D mode and a binary output in the 3D mode to generate timestamps. Strong ambient light is rejected by switching the image sensor to a 3D logarithmic mode from a 3D linear mode.

Abstract: The present invention provides a video coding intra-frame prediction method and a video coding intra-frame prediction device, wherein, the method comprises performing a bidirectional prediction of an intra-frame left and upper direction prediction and an intra-frame right and lower direction prediction on the current coding block to obtain a prediction result; weighting the prediction result obtained. Since the distance between the current coding block and the reference prediction pixel is closer, thus the prediction correlation is high, thus it could achieve the high accuracy prediction of the intra-frame prediction during the process of video coding and thus could improve the coding efficiency.

Abstract: For example, 120 Hz display can be favorably performed on a reception side even in the case of encoding and transmitting moving image data of 24 Hz at the frame rate of 60 Hz. A video stream of a second frame rate larger than a first frame rate is obtained by encoding each picture constituting moving image data of the first frame rate at the second frame rate. Identification information indicating a synchronization relationship between the first frame rate and display start timing is inserted into encoded image data of each picture constituting the video stream of the second frame rate. The video stream of the second frame rate in which the identification information is inserted is transmitted.

Abstract: It is contemplated that the present invention can provide methods and systems for the near-simultaneous frame acquisition from multiple cameras. This can be achieved in two different ways. If the cameras are set to work in triggering mode, the triggering of a first camera and a subsequent camera are adjusted by overlapping the trigger signals and image communication control signals of each camera in order to capture near-simultaneous images from each of the cameras. If the cameras are in video mode, they will be kept synchronous by using a common clock and starting them at the same time. As each camera generates frames, individual, corresponding frames are sampled from each camera in a sequential manner upon receiving a triggering signal. In this way, near simultaneous images can be sampled and saved from multiple cameras in video mode.
