3. Converting Image Formats
Images acquired with FrogEye™ in Raw or BTC formats can easily be
converted to other common formats using the
imgConvert software
included with the purchase of FrogEye™. The control panel for
imgConvert is shown below.
Input controls are on the left side of the window and output controls are
on the right side. Add files or folders to the input list using the buttons
below the list (check the
Recurse box if you want it to convert files in
sub-folders), then choose the output format and location before hitting
the
Convert button.
4. Lens and Filter Selection
Lens Selection
Lens and filter selection is a critical consideration for target clarity, operator’s mobility and special requirements such as
detecting camouflage. FrogEye™ FC-2 integrates two lens mounts:
1. The Canon EF mount supports a large variety of lenses from Canon and other manufacturers. FrogEye™ FLH series
lens hoods are available to seal these lenses against water and dust.
2. The FrogEye™ mount supports special-capability FrogEye™ lenses. FrogEye™ lenses are water and dust proof.
The FL-400 lens for example is a very light-weight, collapsible and underwater transportable design for long-standoff
work in rough environments and beach insertion missions.

Long-Standoff Reconnaissance:
Use sufficient focal length to detect or recognize the target (see table). However, operating distance is often limited by
atmospheric distortions. Try to gain a high vantage point to minimize atmospheric distortions.
