Abstract:
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 the 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, comprising: 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 set 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.
