摘要: To derive a Hamming code to manage data errors a set of at least four parity bit positions is selected for parity bits which will protect a set of data bits (where each data bit has a data bit position in the data bit set). A syndrome is determined for each data bit position. This involves selecting a unique sub-set of at least three parity bit positions. The unique sub-set shares at least one parity bit position with at least one other unique sub-set of at least three parity bit positions. A parity bit value may then be calculated for each parity bit position based on the determined syndromes. The header of a packet may be provided with a word which defines the length of the packet and an error management code generated utilizing this word so that errors in the word may be detected and, possibly, corrected.

摘要: A target pixel and surrounding pixels corresponding to the target pixel are obtained from a digitally represented image. A bilateral high pass filtering kernel is determined based at least in part upon the target pixel and the surrounding pixels. A high pass spatial filtering kernel is provided and multiplied with the high pass photometric filtering kernel to provide a bilateral high pass filtering kernel. The resulting bilateral high pass filtering kernel is thereafter applied to the target pixel and the surrounding pixels to provide a filtered pixel. When it is desirable to combine noise filtering capabilities with sharpening capabilities, the bilateral high pass filter of the present invention may be combined with a bilateral low pass filtering kernel to provide a combined noise reduction and edge sharpening filter. The present invention may be advantageously applied to a variety of devices, including cellular telephones that employ image sensing technology.

摘要: A buffer is associated with each of a plurality of data lanes of a multi-lane serial data bus. Data words are timed through the buffers of active ones of the data lanes. Words timed through buffers of active data lanes are merged onto a parallel bus such that data words from each of the active data lanes are merged onto the parallel bus in a pre-defined repeating sequence of data lanes. This approach allows other, non-active, data lanes to remain in a power conservation state.

摘要: A method and apparatus for image compositing in an apparatus a device in which available memory is at a premium are disclosed. The apparatus includes a first memory that receives a video input signal, in multiple portions. The first memory has a storage capacity less than the entire video image. Data within the first memory is encoded to form encoded video image portions. The entire image is thus encoded, video image portion by video image portion. A second image is combined with image portions in the first memory prior encoding such video image portions. The apparatus may, for example, be an electronic component or components forming a video or image processing pipeline, used in a portable device.

摘要: An n bit D/A decoder is formed using P-type and N-type transistor switches, instead of convention CMOS switches. Each P-type and N-type switch may be formed of fewer transistors than those used to form a CMOS switch, thereby reducing the overall transistor count. The decoder may be used to decode digital values to non-linear GAMMA corrected analog output voltages.

摘要: At least one illuminant white point estimate is determined in a color space having radially defined saturation based on a reference image. A chromatic adaptation correction vector (CACV) is determined based on the at least one illuminant white point estimate. Corrected pixels are obtained by applying the CACV (preferably in a cone response color space using a correction matrix based on the CACV) to uncorrected image pixels corresponding to a target image, which may comprise the reference image or another image.

摘要: A method and apparatus for communicating compressed video information includes storing video information compressed based on a first compression method, such as a method with a high compression ratio, and transcoding the compressed video information to produce corresponding recompressed video information that is based on a second compression method, with a lower compression ratio such as standard JPEG compression or other suitable compression. The method and apparatus, if desired, may include sending the recompressed video information for a destination apparatus which may then suitably decompress the video information using a standard decompression technique. For example, storing the compressed image in a high compressed format, for example, in a piecewise basis may be done online while the camera, for example, is in use so that the image is properly captured and then, transcoding the compressed image to a different level of compression while the camera is offline.

摘要: A system and method are provided for reducing power consumption within a video processing portion of a system. Activity associated within a video-processing portion of a personal digital assistant is analyzed. As reduced activity is identified, power conservation modes are implemented. In a normal mode of operation, a clock signal generated through an external oscillator is provided to a phase locked loop (PLL). An output clock signal from the PLL is then provided to several dividers to generate system clock signals. In a reduced mode of operation, the output clock from the external oscillator is provided to a divider, bypassing the PLL. Video processing components then use clock signals based on the external oscillator. In a suspend mode, both the PLL and the external oscillator are disabled.
