Image CaptureImage Capture
There are two computer programs that we use with the images: an image analysis program is used for making measurements etc.; we use NIH image which is free of charge and a copy of it comes with the framegrabbers which they call Scion Image. The other program is Adobe Photoshop, the industry standard for image manipulation. Both of these programs will accept images directly from the framegrabbers; NIH image acquires photos from within the program directly; Photoshop does it with a plug-in that goes in the Acquire menu, which can be downloaded from the Scion web site but in the future it will come with the framegrabber software.
Obtain your raw images from the video by capturing the image with the highest magnification possible on the microscope and at the largest size available to the framegrabber (Width 640, Height 480 pixels). If you have done this, the image appears on your screen in 72 dpi with the dimensions of about 9" width and 6.5" height with a size of about 900 kb. There is a small size difference in the images obtained from the 2 framegrabbers. But the main difference in the framegrabbers of the 2 computers is the newer AG-7 board gives live color images making image capture much easier. When we bought the first framegrabber, the live-color-capture boards were not available yet, so the LG-3 captures the image in color but works with live-black-and-white. We prefer working with the live-color board.
