A method, comprising: receiving, by image processing circuitry (124; 602) configured to compress color image data, color image data representing a color image from an imaging system having chromatic aberration, the color image including a first, green, color channel and a second color channel that is a red or blue color channel, the first color channel forming a first image (310(G)) and the second color channel forming a second image (310(R), 310(B)), the chromatic aberration of the imaging system producing a separation between an edge of the first image (310(G)) and an edge of the second image (310(R), 310(B)) and being represented as vector displacements between the edge of the first image (310(G)) and the edge of the second image (310(R), 310(B)), the vector displacements being weighted according to proximity to the edge of the second image (310(R) , 310(B)); performing, by the image processing circuitry (124; 602), a chromatic aberration correction operation on the color image data to produce corrected color image data representing a corrected color image, the chromatic aberration correction operation being based on the chromatic aberration of the imaging system, the corrected color image having a reduced separation between the edge of the first image (310(G)) and the edge of the second image (310(R) , 310(B)) represented by the weighted vector displacements; and performing, by the image processing circuitry (124; 602), an image compression operation on the corrected color image data to produce compressed color image data, the compressed color image data having fewer bits of information than the corrected color image data. receiving, by image processing circuitry (124; 602) configured to compress color image data, color image data representing a color image from an imaging system having chromatic aberration, the color image including a first, green, color channel and a second color channel that is a red or blue color channel, the first color channel forming a first image (310(G)) and the second color channel forming a second image (310(R), 310(B)), the chromatic aberration of the imaging system producing a separation between an edge of the first image (310(G)) and an edge of the second image (310(R), 310(B)) and being represented as vector displacements between the edge of the first image (310(G)) and the edge of the second image (310(R), 310(B)), the vector displacements being weighted according to proximity to the edge of the second image (310(R) , 310(B)); performing, by the image processing circuitry (124; 602), a chromatic aberration correction operation on the color image data to produce corrected color image data representing a corrected color image, the chromatic aberration correction operation being based on the chromatic aberration of the imaging system, the corrected color image having a reduced separation between the edge of the first image (310(G)) and the edge of the second image (310(R) , 310(B)) represented by the weighted vector displacements; and performing, by the image processing circuitry (124; 602), an image compression operation on the corrected color image data to produce compressed color image data, the compressed color image data having fewer bits of information than the corrected color image data. <EOS>
