cn A B 7 Note that this should not be necessary if the position of the targets has not moved significantly between frames and the alignment procedure was carried out in the previous tab. 29) If the image is too dark or light and the targets cannot be seen clearly, click View > Toolbar and check the “Display Control” box. This will bring up a slider which allows the brightness to be adjusted. This change is purely for visual purposes and will not alter the data. 30) The resultant matrix for the IRR image is shown in columns O (at 016, Figure 3-52). The matrix for the UVR image is shown in column A (at A8, Figure 3-53). 31) The matrices generated for the IRR and UVR images are matched with that for the VIS image by linear regression (see columns O and A). The corrected IRR and UVR images can be observed by scrolling down to columns O (034) and A (A16). Applying an output ICC profile which converts the corrected IRR and/or UVR image to sRGB (or RGB16) colour space. 32) Click on the “results” tab to the right. An output ICC profile is automatically applied to the results at O34 and A16 of the “specden’” tab which converts the corrected IRR and UVR images to SRGB (or RGB16) colour space (B6 and B7, Figure 3-54).
