Scale Multiplies the image to the right by this value to increase brightness. To avoid saturation, make sure that this number times the max value below is less than 255. |
Selector Selects which kind of correction is appied to the image. Shifted Raw only duplicates the raw image from above in the two halves of the image with every-other-line in the right half shifted by seven pixels. Corrected Center to Left applies the correction algorithm starting near the center of the image and working to the left. Corrected Center to Right applies the correction algorithm starting near the center of the image and working to the right. Correcteds Averaged applies both Left and Right correction processes and averages them. |
go Press this button after changing any of the correction parameters to see the new results. |
Offset Adds a filtered offset to overcome the affects of the baseline stabilization circuitry that incorrectly reduced the values of all the pixels. The optimum setting will produce the same average brightness in the two halves of the image when the Selector is set for "Corrected Center to Left" or "Corrected Center to Right" and will reduce shadows. It is also desired to find a value that does not allow the min value to go too far negative. |
12>13 This and all the similar buttons overwrites columns of pixels to eliminate hot pixels. The column numbers start at 1 and go to 400. |

Scale The image below is scaled (multiplied) to increase the brightness. Keeping the product of the max value and the Scale below 255 assures that the picture is not saturated. |

TIFF Outputs the corrected image as a TIFF file and quits the program. |
Stripe Filter A special notch filter designed to eliminate patterns with a width of seven pixels. |
Ghost Filter A special filter designed to enhance detail and reduced ghosting caused by the Stripe Filter. |
Image The corrected image. |
Output Array The allows the numeric values to be applied to another program. |
File path The source pathname of the original picture in vicar format. |
max value The maximum DN value from the original picutre. |
Raw image The original picture with the correct aspect ratio. |
max value The maximum value in the corrected image. Keep this value below 255 to assure that the image does not saturate. |
min value The minimum value of the corrected image. It can go negative due to the fact that the corrections subtract values from one half of the image and add them to the other half. It is desireable to not let this value go too far negative. |
