The MARCI instruments provide images in many colors using "pushframe" imaging. A filter array consisting of a series of strip filters is mounted to the CCD, oriented so the short axes of the strips are parallel to the scan direction. The CCD is read out each time the field sweeps through the width of one of the filter strips, providing overlapping coverage in each of the color bands. This provides narrowband color coverage without a mechanical shutter or filter wheel. The above image was taken with the Mars Climate Orbiter (MCO) Mars Color Imager Wide Angle flight unit during calibration. The instrument was mounted on a rotation stage, which was rotated to scan out this image. The individual framelets were not corrected for geometric distortion, so there is color misregistration at the edge of the field. A number of the MARCI Science Team appear at the left of the image.
