SPOT 4.1 Basic and Advanced Software Manual for SPOT Insight ...

Ch. 15 – Using Other Windows Imaging Application in Basic ModeDefining PreferencesIn the Basic TWAIN Interface, you can define three capture/viewpreferences. Click on the Prefs button to open the Preferenceswindow (see right). Each option is described below:Captured Image Bit DepthThis option enables you to specify a different image bit depth whensaving an image captured in the SPOT program.• 8 Bits per Channel – The 8 bits per channel option provides 256gray levels per color:a) With Insight B/W cameras, captured images are 8 bits perpixel monochrome.b) With Insight Color cameras, captured images are 24 bits perpixel RGB color.This option results in smaller, more manageable image sizes, and is best for images that do not requireextensive modification.• 12 Bits per Channel – The 12 Bits per channel option provides 4,096 gray levels per color.c) With Insight B/W cameras, captured images are 12 bits per pixel monochrome.d) With Insight Color cameras, captured images are 36 bits per pixel RGB color.This option reduces banding problems that can result with modified images, but also results in largerfile sizes.When saving 12 bit per channel images, SPOT prompts you to select either 12 bits per channel or 16bits per channel. If you use Adobe’s Photoshop for image editing, you should select the 16 bit perchannel option because Photoshop cannot read 12 bit per channel images.Note: The SPOT Insight camera captures all images using 10 bits per channel (color). The SPOTsoftware immediately converts the captured image to either 8 bits per channel (color) or 12 bits perchannel (color), depending on the Captured Image Bit Depth that you select.Keep TWAIN Window on TopChecking this option ensures that the TWAIN window remains the top-most window when working inmultiple applications. This allows you to preview and transfer or acquire multiple images without havingto re-open the SPOT window. If the Keep This Window on Top box is checked, the SPOT Camerawindow remains open. If the box is not checked, the window automatically closes after each image istransferred or acquired.Always Show Full Chip in Live ModeChecking this option ensures that you will always see the Full Chip view when viewing a live image. Keepin mind that the selection that you make here determines how the live image displays when viewing aregion of the chip.
