    • A method and apparatus for processing a scan line of image data, wherein image data from portions of the scan line is processed simultaneously along plural channels, each channel processing a portion of the image data, and provided with context information from an adjacent portion of the scan line. Context pixels are added at the trail edge of a first scan line portion, derived from the lead edge of a second scan line portion. In certain image processing requiring preceding and succeeding pixel context information, subsequent to processing, on correctly processing pixels are transferred for subsequent processing, and pixels at the trail edge of a first scan line portion, and the lead edge of a second scan line portion are not transferred, leaving complementary scan line portions.
    • 一种用于处理图像数据的扫描线的方法和装置,其中来自扫描线的部分的图像数据被同时沿多个通道被处理,每个通道处理图像数据的一部分,并且提供有来自相邻部分的上下文信息 扫描线。 在从第二扫描线部分的引导边缘导出的第一扫描线部分的尾部边缘处添加上下文像素。 在需要前后像素上下文信息的某些图像处理中,在对正确处理像素的处理之后,传送用于后续处理的处理,并且第一扫描线部分的尾部边缘处的像素和第二扫描线部分的引导边缘 不传输,留下补充扫描线部分。
