    • A technique for processing at least one bad pixel occurring in an image sensing system is provided. Dynamic bad pixel detection is performed on a plurality of streaming pixels taking from at least one controlled image and value and coordinate information for each bad pixel is subsequently stored as stored bad pixel information. Thereafter, static bad pixel correction may be performed based on the stored bad pixel information. The stored bad pixel information may be verified based on histogram analysis performed on the plurality of streaming pixels. The technique for processing bad pixels in accordance with the present invention may be embodied in suitable circuitry or, more broadly, within devices incorporating image sensing systems.
    • 提供了用于处理在图像感测系统中出现的至少一个不良像素的技术。 对从至少一个受控图像获取的多个流像素执行动态坏像素检测,并且随后将每个坏像素的坐标信息存储为存储的不良像素信息。 此后,可以基于存储的不良像素信息来执行静态坏像素校正。 可以基于对多个流式像素执行的直方图分析来验证存储的不良像素信息。 根据本发明的用于处理不良像素的技术可以体现在合适的电路中,或者更广泛地体现在包括图像感测系统的设备内。

    • 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.
    • 为了导出用于管理数据错误的汉明码,为奇偶校验位选择一组至少四个奇偶校验位位置,这将保护一组数据位(其中每个数据位在数据位集合中具有数据位位置)。 确定每个数据位位置的综合征。 这涉及选择至少三个奇偶校验位位置的唯一子集。 唯一子集与至少一个其他唯一的至少三个奇偶校验位位置的子集共享至少一个奇偶校验位位置。 然后可以基于所确定的校正子针对每个奇偶校验位位置计算奇偶校验位值。 分组的报头可以被提供有定义分组的长度的单词和使用该单词生成的错误管理代码,从而可以检测单词中的错误并且可能被校正。
