Description

This data consists of color images reconstructed by the Image Processing Laboratory (IPL) of the Jet Propulsion Laboratory. Color elements of the same scene shuttered three times, seconds apart, are recombined using software developed for this purpose. These triplets are usually obtained by using the red, green and violet filters; however, in some cases the blue filter is substituted for the violet. In false color reconstruction, it is necessary to take "perception" into account. Each frame is produced in two ways. The first is the Martian surface as the computer says it must be within a perceptual range of what a group of viewers say they will tolerate. This, in combination with color distortions generated by the GRE (playback device), film, photographic paper, and photolab procedures, produces images which vary slightly in color. The second production is not limited by perceptual parameters.
