MARDI color adjustment example from the 35th frame acquired during descent from an altitude of 9.75 km. (a) Original image received from Mars, which had been losslessly compressed on board, to which the same Bayer pattern interpolation as can be performed on board the instrument was applied after receipt. This is from NASA PDS archive EDR product 0000MD0000000000100035C00_XXXX. (b) Same image with color adjustment as applied to radiometrically corrected NASA PDS archive RDR product (_DRCX). (c) Same color processing as in Figure 19b and also geometrically linearized to adjust for the lens distortion (archive produce _DRLC). The heat shield is circular, 4.5 m in diameter, about 12.8 m from the camera, and tilted about 20°.
