Custom Camera Control
Application
Camera control software compatible with the IL3.
DHCP
DHCP is a utility by which a server dynamically assigns IP addresses to clients on a
network. When DHCP is selected in the Network Menu, the camera will allow a server on
a connected network to assign it an IP address.
Dialog
A Dialog is a box that requires user input such as the selection of an option, or the
entering of a number or text.
Download
Electronically moving image data from a camera to a “remote” device, i.e. a PC or other
mass storage.
Enable Raw
A raw image is one where all image processing including colorization, white balance,
brightness, contrast, and gamma, are all bypassed.
File Type
Digital files are commonly identified by their extensions. Familiar types include PDF,
TXT, JPEG,TIFF, DOC, MP3, etc. Each of these files has a specified format that usually
includes information in the file header and specially formatted data that applications on
PCs, Cameras, Printers, Smartphones, and other electronic devices can read, write, and
decipher for human viewing, editing, listening, etc.
Gain
In imaging the term Gain is most often used as a multiplier applied to a pixel value.
Gamma
Gamma encoding of images is required to compensate for properties of human vision
- to maximize the use of the bits or bandwidth relative to how humans perceive light
and color.[1] Human vision under common illumination conditions (not pitch black or
blindingly bright) follows an approximate gamma or power function. If images are not
gamma encoded, they allocate too many bits or too much bandwidth to highlights that
humans cannot differentiate, and too few bits/bandwidth to shadow values that humans
are sensitive to and would require more bits/bandwidth to maintain the same visual
quality-
HDMI
HDMI, High-Definition Multimedia Interface, is used to transmit digitized video
(and audio) data from the camera to a remote display. This is a popular method for
connecting consumer products such as televisions, cable TV boxes, DVD players, etc.
Image Memory
Image memory is the internal memory in the camera reserved for raw image data. This is
volatile memory that is erased when the camera is shut down.
JPEG Stack
Joint Photographic Expert Group (JPEG) file format is a highly compressed file format,
capable of reducing image files to a fraction of the size of a BMP or lossless TIFF. The
image quality of JPEGs is excellent, although there may be some discernible noise in the
displayed image, often referred to as JPEG artifacts.
Menu
Once an item in the Menu Bar is selected, the corresponding Menu appears below.
Menu Bar
The Menu Bar is the bar across the top of the camera display that lists the Menu Items.
Network
The camera may be connected to one or more computers via its RJ45 GigE (Gigabit
Ethernet) connection.
NTP Time
Network Time Protocol: Network Protocol for synchronizing time clocks of devices at
-
tached to a given network or internet, within a few hundredths of a second.
Play/Review Bug
In Review there is a progress bar that graphically indicates the position of the currently
viewed frame within the image sequence. The small vertical line that is used as the indi
-
cator is referred to as the Review Bug.
Record
The camera is acquiring images and storing them in internal memory. This begins when
the camera is armed, and ends after a trigger is received.
Record Bar
When the camera is Armed and it commences capturing images, the Record Bar presents
a graphic indication of the progress of filling the buffer.
Refresh Rate
Rate at which image data is re-painted on the display. For CRTs this is analogous to the
vertical frequency.
