A single MI image or an Microscopic Imager mosaic can be merged with Pancam color images. The two products must be coregistered first, and then added together to produce colorized images in which the intensity comes from the MI and color (hue/saturation) comes from the Pancam images. This method of colorizing data may not yield a satisfactory product if the solar illumination is from a different direction in the Pancam relative to the MI images, or if the images are partly shadowed. It can be difficult to find where the MI overlaps the Pancam due to the scale difference (roughly a factor of 20) and differences in illumination, especially for soil targets.
