1. A method for processing image data using an image signal processing system comprising:

  • using a digital image sensor to acquire raw image data comprising a plurality of raw pixels representative of an image scene;

    providing the raw pixels to a raw image processing pipeline comprising a set of line buffers;

    processing the raw pixels using the raw image processing pipeline, wherein processing the raw pixels using the raw image processing pipeline comprises;

    applying a first set of gain, offset, and clamping parameters to the raw pixels using gain, offset, and clamping logic implemented in a first line of logic;

    using defective pixel correction logic implemented using a first line of logic and a first subset of the set of line buffers to apply a defective pixel correction operation to the raw pixels;

    using noise reduction logic implemented using the set of line buffers to apply noise reduction to the raw pixels;

    using lens shading correction logic implemented using a second subset of the set of line buffers to apply lens shading correction to the raw pixels;

    applying a second of gain, offset, and clamping parameters to the raw pixels using the second subset of line buffers; and

    using demosaicing logic implemented using the second subset of line buffers to demosaic the raw pixels into corresponding color RGB pixels.
