PASSING EMBEDDED DATA THROUGH A DIGITAL IMAGE PROCESSOR

摘要

A device (30) for processing an image includes a buffer memory (42), which is configured to receive and store an input data stream including multiple image lines and one or more embedded data lines, which are interleaved with the image lines and include metadata that are not a part of the image. An image processor (46) receives the input pixel values in succession from the buffer memory and processes the input pixel values so as to generate an output data stream including output pixel values, which are different from the input pixel values. A processing controller (54) detects the one or more embedded data lines and controls the image processor, responsively to detecting the one or more embedded data lines, so that the embedded data lines pass through the image processor without modification of the metadata and are interleaved with the image lines of the output pixel values in the output data stream.
