Review
Review is a camera utility for viewing image data while it resides in camera memory. It
includes options for playing the imagery as a movie, forward or backward, or stepping
through the frames one at a time, or stepping through every 10th frame. It also allows
the user to adjust starting and ending points for an image sequence for viewing or sav
-
ing. The user may adjust image properties such as brightness, contrast, gamma, color
balance when reviewing the images. If 10 bit images have been saved, the user may also
select which 8 bits to display. It is important to note that image adjustments made while
using Review do not alter the image data in camera memory although they do alter the
viewed and saved images.
Save
Moving image data from a camera’s internal memory to some other mass storage device.
This mass storage may be local, such as the SSD drive within the camera, or remote, such
as a PC.
SD
This is Secure Digital memory, such as the SD-card used as a plug-in mass storage device
for the camera.
SSD
Solid-state hard drive that is located inside the camera. This is a non-volatile mass stor
-
age device retains its data when the camera is powered down.
Static IP
In order for one networked device to “talk” to each other, they need to have compatible
IP addresses. One way to assure this is for the user to assign unchanging (static) IP
addresses to each device.
Status Menu Bar
The Status Bar is a line of text at the bottom of the display that appears when the
camera menus are turned on.
Sub Menu
Within each Menu, there may be additional Sub Menus from which to select.
TIFF Stack
Tagged Image File Format (TIFF) is a much more flexible format than the BMP, in that
it may use one of several compression schemes, may be used to store multiple images
(multi-page TIFF), and may include metadata in the form of Tags. Developers may apply
for their own block of private Tags. The TIFF is the only file format used in the IL3 that
is compatible with 10-bit images. The TIFF Stack produced by the IL3 is a collection of
frames, written as BMP files representing a captured video sequence.
Trigger
The trigger is a signal sent to the camera either via the trigger switch on the camera
or from an external source applied to the camera’s trigger input connector. When an
armed camera receives a trigger, it will capture and write a prescribed number of frames
into camera memory, then stop capturing images. If the IL3 receives a Trigger while in
Live Mode, it will take a still image.
Update Rate
The rate at which the IL3 or a PC can process a new frame of video and send it to the
display.
USB
A thumb drive or some other mass memory device may be attached via the USB port of
the camera.
USB OTG
When a PC is connected to the USB OTG (USB On The Go) port of the camera, the
camera appears as a mass storage device to the PC, much like plugging a thumb drive
into a PC’s USB port. The camera is automatically a slave to the PC.
Web Application
Camera control software that runs via web browser such as Windows Internet Explorer,
Safari, Firefox, etc.
White Balance
Many different kinds of illumination may be used with high speed cameras. Typical color
temperatures for common types of illumination are used to compute RGB gains, which,
when applied to captured imagery, should approximate what a human would perceive
as accurate color. The term White Balance refers to the idea that, presented with a white
card under a given light source, the camera should produce a white image.
