    摘要： A color image processing pipeline performs an interpolation on color data to generate triplets located at distinct pixel locations. The pipeline includes defect correction and image enhancement blocks having a first color interpolation block for generating RGB information for each pixel of an input image pixel pattern, and a second color interpolation block for receiving the RGB information to provide enhanced RGB pattern pixels. Dedicated line memories and delay circuits associated with the defect correction and image enhancement blocks permit real-time processing of pixel data. First and second read/write buffers store a subset or pixel block of the image data, and invert a scanning mode of pixel data being fed to the dedicated line memories and delay circuits associated to at least the first color interpolation block, from row-wise to column-wise, for each subset of data to be stored therein.

    摘要： An image generating pipeline (IGP) includes a digital signal processor for implementing processing blocks connected in cascade for processing an input image that includes an array of raw pixel values to generated a color image that includes an array of reconstructed pixel values. A memory is coupled to the digital signal processor for storing the raw pixel values and the array of reconstructed pixel values. The digital signal processor includes a data cache, and the raw pixel values of the input image are processed through the processing blocks in sub-arrays having fractional dimensions of the pixel-dimensions of the whole image array. The sub-arrays include an input sub-array of pixel values being loaded from the memory for defining a working window. The sub-arrays of raw pixel values have a row-wise dimension of at least a fraction of a full row of the input-image, and a column-wise dimension equal to or larger than a column-wise filtering action of a respective processing block to which the input sub-array is input. The digital signal processor outputs at least one fraction of full rows of completely reconstructed pixel values of the input image for storing in the memory.

    摘要： A method of processing digital images to reduce the effects of color bleeding. Chrominance components for pixels in a working window are determined and weights are assigned to the pixels in the working window. A chrominance correction for a center pixel in the working window is generated based on the chrominance components and the assigned weights. Fuzzy variables and thresholds may be applied to generate the assigned weights and the chrominance correction.
