  • Publication number: 20230097950
    Abstract: The invention relates to a method for providing an environment image (36) on the basis of a camera image (30) of a vehicle camera (14, 16, 18, 20) of a vehicle (10) for monitoring an environment (28) of the vehicle (10), the camera image (30) comprising a camera image area having a camera resolution, for further processing, in particular by means of a driving assistance system of the vehicle (10), the method comprising the steps of: ascertaining a position of the vehicle camera (14, 16, 18, 20) on the vehicle (10), capturing at least one current motion parameter (44) of the vehicle (10), determining a current focus area (32) within the camera image (30) on the basis of the position of the vehicle camera (14, 16, 18, 20) on the vehicle (10) and on the basis of the at least one current motion parameter (44), and transferring pixels of the camera image (30) into the environment image (36), pixels from the current focus area (32) being transferred, with a first resolution, into a first image area (40) of the envi

  • Patent number: 8605217
    Abstract: Displaying a stream of video data on a display device may be performed by decoding a portion of the video data to form a video frame. A queue time is determined when the video frame should be displayed. The queue time is adjusted by a margin time relative to a next display time to compensate for interrupt jitter, wherein the margin time is less than a period of time between periodic display time events and is larger than a specified interrupt jitter time. A software interrupt event is set to occur corresponding to the adjusted queue time. The video frame is queued in response to occurrence of the software interrupt. The queued video frame is transferred to a display buffer for the display device upon the occurrence of a next display time event after the occurrence of the software interrupt.

  • Patent number: 7864191
    Abstract: A system comprising a storage including an image file associated with a plurality of pixels and processing logic coupled to the storage. The processing logic is adapted to determine an average of least significant bits associated with a maximum of two of the plurality of pixels, add the average to bits associated with a target pixel, and disassociate from the target pixel least significant bits of the target pixel. No pixels are disposed between the target pixel and each of the two of the plurality of pixels.

  • Publication number: 20070041653
    Abstract: Systems and methods for quantization are provided. Some embodiments provide a system and method for quantization comprising preprocessing the transform coefficients to predict one or more non-zero coefficients and one or more zero coefficients as well as predict the non-existence of non-zero and zero coefficients, storing indices representing the predicted non-zero coefficients, and performing a quantization process on the predicted non-zero coefficients, as well as the inverse quantization process of those non-zero quantized coefficients.

  • Patent number: 7145573
    Abstract: Combining a graphics object with a picture where only the luminance value of a graphics object pixel is written to a corresponding picture pixel if the chrominance values of the graphics object pixel indicate transparency and yet the luminance value indicates non-transparency.

  • Patent number: 7119845
    Abstract: Image resizing through resampling by poly-phase filtering with a phase generation from input parameters but with lower resolution of the phase for filter selection. Field and frame mode selection creates initial offsets for alignment. A phase accumulator generates sample addressing with its most significant bits, generates filter selection with its middle bits, and maintains its least significant bits for accuracy.

  • Patent number: 5274674
    Abstract: For controlling the threshold of a threshold decoder with a logic signal having several levels (for example a duobinary signal) which may be affected by echoes, and in which the threshold value of the decoder is programmable, the threshold of the decoder is adapted in dependence upon the measurement of the binary error rate, when there are echoes.
