In-line chromatic aberration correction in wide dynamic range (WDR) image processing pipeline

An image processing pipeline comprising:

• an image processor configured to receive an input image and perform image processing on the input image to generate a formatted image;
• first circuitry coupled to the image processor, the first circuitry including:
• a timing control circuit having an input configured to receive input pixels of the formatted image and an output configured to output processed pixels of a chromatic aberration (CA) corrected image,
• a lookup table (LUT) configured to store a multidimensional array of grid points representative of a sampling of an output of an image sensor and associated shift values for each grid point,
• a first interpolation circuit coupled to the LUT,
• a memory interface coupled to the timing control circuit,
• a memory coupled to the memory interface, and
• a second interpolation circuit coupled to the timing control circuit and to the memory interface;
• second circuitry coupled to the first circuitry, the second circuitry configured to process the CA corrected image to generate a processed image;
• a first color processor coupled to the second circuitry and configured to generate a first color processed image based on the processed image;
• a second color processor coupled to the first circuitry and configured to generate a second color processed image based on the CA corrected image;
• and
• output circuitry coupled to each of the first color processor and the second color processor and configured to combine the first and second color processed image to generate an output image.
