| IEEE 1394 Trade Association | 1394 Trade Association is a non-profit industry association devoted to
the promotion of and growth of the market for IEEE 1394-compliant
products. Participants in working groups serve voluntarily and without
compensation from the Trade Association. Most participants represent
member organizations of the 1394 Trade Association. The specifications
developed within the working groups represent a consensus of the
expertise represented by the participants. Background of the Trade
Association and IEEE 1394. The 1394 Trade Association was founded in
1994 to support the development of computer and consumer electronics
systems that can be easily connected with each other via a single serial
multimedia link. The IEEE 1394 multimedia connection enables simple,
low cost, high bandwidth isochronous (real time) data interfacing
between computers, peripherals, and consumer electronics products such
as camcorders, VCRs, printers, PCs, TVs, and digital cameras. With IEEE
1394 compatible products and systems, users can transfer video or still
images from a camera or camcorder to a printer, PC, or television, with
no image degradation. The 1394 Trade Association includes more than 170
companies and continues to grow. Members of the 1394 Trade Association.
The 1394 Trade Association is comprised of more than 170 member
companies. |

IIDC V1.30
| IIDC 1394-based Digital Camera
Specification Version 1.30 July 25, 2000. The purpose of this document
is to act as a design guide for digital camera makers that wish to use
IEEE 1394 as the camera-to-PC interconnect. Adherence to the design
specifications contained herein do not guarantee, but will promote
interoperability for this class of device. The camera registers, fields
within those registers, video formats, modes of operation, and controls
for each are specified. Area has been left for growth. To make
application for additional specification, contact the 1394 Trade
Association Instrumentation and Industrial Control Working Group,
Digital Camera Sub Working Group (II-WG DC-SWG).

IIDC V1.31
| IIDC V1.31 was published in January
2004, evolving the industry standards for digital imaging communications
to include I/O and RS232 handling, and adding additional formats |
| ILUT
| Input Look Up
Tables (a.k.a. format RAM): used for image data manipulation, ILUTs
convert digitized image data in real-time and are often used to invert,
threshold, or perform grayscale translations on the image. |
Image Exclusive OR
| Performs an Exclusive OR operation
between the original input image and a constant or another image stored
in the buffer. This is a bit-wise operation. |
Image Logical Difference
| Finds the logical difference between
the original input image and a constant or another image stored in the
buffer. This is a bit-wise operation. |
Image Mask
| Replaces pixels in the original input image that correspond to pixels
with value 0 in the image mask as 0. The image mask is an 8-bit image
that specifies the regions in the original input image to be modified.
This is a pixel-by-pixel operation. |
Image Max
| Extracts the largest value between the original input image and a
constant or another image stored in the buffer. This is a pixel-by-pixel
operation. |
Image Min
| Extracts the smallest value between the original input image and a
constant or another image stored in the buffer. This is a pixel-by-pixel
operation. |
Image Not And
| Performs a logical NAND operation between the original input image and a
constant or another image stored in the buffer. This is a bit-wise
operation. |
Image Not Exclusive OR
| Performs an Exclusive NOR operation between the original input image and
a constant or another image stored in the buffer. This is a bit-wise
operation. |
Image Not OR
| Performs a logical NOR operation between the original input image and a
constant or another image stored in the buffer. This is a bit-wise
operation. |
Image OR
| Performs a logical OR operation
between the original input image and a constant or another image stored
in the buffer. This is a bit-wise operation. |
Image Processing
| In the broadest sense, image processing includes any form of information
processing in which the input is an image. Many image processing
techniques derive from the application of signal processing techniques
to the domain of images — two-dimensional signals such as photographs or
video. Typical problems are: • Geometric transformations such as
enlargement, reduction, and rotation • Color corrections such as
brightness and contrast adjustments, quantization,. or conversion to a
different color space. • Combination of two or more images, e.g. into
an average, blend, difference, or image composite. • Interpolation,
demosaicing, and recovery of a full image from a mosaic image (e.g. a
Bayer pattern, etc.). • Noise reduction and other types of filtering,
and signal averaging. • Edge detection and other local operators. •
Segmentation of the image into regions. |
| Image Processor Board
| For purposes
of the MV market study, an Image Processor Board is the same as a Vision
Processor Board and Embedded Vision Processor Board. Unlike Frame
grabbers, these boards are characterized by complex image processing
capabilities; that is, they typically have more than 2 image processing
functions. Also see "Frame grabber". |

| Imaging Sensor Chip
| A sub-component in a camera that converts light reflected off an image into electrical pulses for capture and manipulation |
Image Source
| The original input image. |
Imaging Addition
| Adds a constant or an image to the original input image. This is a pixel-by-pixel operation. |
Imaging And
| Performs a logical AND operation between the original input image and a
constant or another image stored in the buffer. This is a bit-wise
operation. |
Imaging Divide
| Divides the original input image by a constant or another image. This is a pixel-by-pixel operation. |
Imaging Multiply
| Multiplies the original input image by a constant or another image. This is a pixel-by-pixel operation. |
Image Subtraction
| Subtracts a constant or an image from the original input image. This is a pixel-by-pixel operation. |
| Infrared | Infrared (abbr. IR) is the region beyond the visible spectrum at the red end, typically greater than 770 nm. see IR cut filter |
Interline Transfer CCD
| Interline transfer CCD or just interline CCD is a type of CCD in which
the parallel register is subdivided so that, like a Venetian blind,
opaque strips span and mask the columns of pixels. The masks act as
storage areas. When the CCD is exposed to light, the image accumulates
in the exposed areas (photosites) of the parallel register. In the
serial register, the entire image is under the interline mask when it
shifts for CCD readout. It is possible to shift the integrated charge
quickly (200 ns) under the storage areas. Since these devices function
as a fast shutter (or gate), they are also sometimes referred to as
gated interline CCDs. >> See microlens |
| IR | IR is the abbreviation for Infrared
|
IR Cut Filter
| As color cameras can see infrared radiation as well as visible light,
these cameras are usually equipped with an IR cut filter, to prevent
distortion of the colors the human eye can see. To use the camera in
very dark locations or at night, this filter can be removed, to allow
infrared radiation to hit the image sensor and thus produce images. |
| Isochronous Transmission Mode | Isochronous transmission mode is a mode supported by IEEE 1394
(FireWire). IEEE 1394 supports a guaranteed data path bandwidth and
allows for real-time transmission of data to/from 1394 devices.
Isochronous data transfers operate in a broadcast manner, where one or
many 1394 devices can listen to the data being transmitted. The emphasis
of isochronous data transfers is placed on guaranteed data timing
rather than guaranteed delivery. Multiple channels (up to 16) of
isochronous data can be transferred simultaneously on the 1394 bus.
Since isochronous transfers can only take up a maximum of 80 percent of
the 1394 bus bandwidth, there is enough bandwidth left over for
additional asynchronous transfers. >> See also Asynchronous
transmission mode |
