  • Patent number: 11368692
    Abstract: Systems, apparatuses, and methods for generating a model for determining a quantization strength to use when encoding video frames are disclosed. A pre-encoder performs multiple encoding passes using different quantization strengths on a portion or the entirety of one or more pre-processed video frames. The pre-encoder captures the bit-size of the encoded output for each of the multiple encoding passes. Then, based on the multiple encoding passes, the pre-encoder generates a model for mapping bit-size to quantization strength for encoding video frames or portion(s) thereof. When the encoder begins the final encoding pass for one or more given video frames or any portion(s) thereof, the encoder uses the model to map a preferred bit-size to a given quantization strength. The encoder uses the given quantization strength when encoding the given video frame(s) or frame portion(s) to meet a specified bit-rate for the encoded bitstream.

  • Patent number: 11323630
    Abstract: Definition is calculated for each pixel in a plurality of captured images while changing a focal position. For each coordinates, an image reference value indicating the number of a to-be-referenced captured image is determined. Then, a luminance value is calculated for each coordinates on the basis of the image reference value and the definition. At this time, the luminance value in the captured image indicated by the image reference value of peripheral coordinates is reflected in the luminance value in the captured image indicated by the image reference value of each coordinates. The calculated luminance values are combined to generate an omnifocal image. Accordingly, a smooth omnifocal image is generated. The image reference values themselves are not changed. This prevents unnecessary luminance values of pixels existing in captured images that ought not to be referenced from appearing in the omnifocal image.

  • Patent number: 11297276
    Abstract: A method and system for acquiring data from a pixelated image sensor for detecting charged particles. The method includes reading a pixel voltage of one or more of the multiple pixels multiple times without resetting the image sensor and digitizing the pixel into a first number of bits. The camera outputs a digitized compressed pixel voltage in a second, less, number of bits. The maximum range of the digitized compressed pixel voltage is less than a maximum range of the pixel voltage.

  • Patent number: 11294448
    Abstract: Mobile devices, such as smartphones, are severely battery-limited. The capabilities of mobile device processors have increased at exponential rates, but battery technologies have improved at much slower rates. As a consequence, it is ever more important that mobile devices be operated in battery-preserving manners. An aspect of the present technology concerns methods and arrangements enabling on-going recognition-processing of imagery and audio by different detectors, without the high battery drain that has characterized the prior art. A variety of other features and arrangements are also detailed.

  • Patent number: 11285873
    Abstract: A method for generating surround view images derived from image data captured by cameras of a vehicular surround view vision system includes equipping a vehicle with a plurality of cameras disposed at the vehicle. Image data is captured by the cameras and provided to a control of the vehicle. The provided captured image data is processed to generate a first three-dimensional representation in accordance with a first curved surface model as if seen by a virtual observer from a first virtual viewing point exterior of the vehicle having a first viewing direction. The first representation is output to a display screen of the vehicle for display to the driver of the vehicle. Responsive to actuation of a user input, the processing is adjusted to generate a second three-dimensional representation in accordance with a second curved surface model, and the second representation is output to the display screen.

  • Patent number: 11275967
    Abstract: A computational method is disclosed for producing a sequence of high-resolution (HR) images from an input sequence of low-resolution (LR) images. The method uses a structured subspace framework to learn pairs of LR dictionaries from the input LR sequence ‘and’ employ learned pairs of LR dictionaries into estimating HR images. The structured subspace framework itself is based on a pair of specially structured HR basis matrices, wherein a HR basis spans any HR image whose so-called polyphase components (PPCs) are spanned by the corresponding LR dictionary.

    Abstract: Rate control techniques are provided for encoding an input video sequence into a compressed coded bitstream with multiple coding passes. The final coding pass may comprise final splices with non-overlapping frames that do not extend into neighboring final splices. A final splice in the final coding pass may correspond to at least one non-final splice in a non-final coding pass. A non-final splice may have overlapping frames that extend into neighboring final splices in the final coding pass. The overlapping frames in the non-final splice may be used to derive complexity information about the neighboring final splices. The complexity information about the neighboring final splices, as derived from the overlapping frames, may be used to allocate or improve rate control related budgets in encoding the final splice into the compressed coded bitstream in the final coding pass.
