Overview
The six models of the XCD-series digital camera
modules (Black and white models and RAW color
models) employing the IEEE1394b-2002 standard are
equipped with quality digital camera features.
Although it is compact, the camera allows high-speed
image transfer and daisy chain connection with two
IEEE1394b connectors. The camera also has versatile
features such as hardware preprocessing in the camera
that reduces the load of image processing in a PC, bus
synchronization, and broadcast delivery of commands.
The XCD-series digital output cameras conforming to
the IIDC 1.31 protocol take full advantages of
IEEE1394 capabilities.
Main Features
High image quality, high-speed image
output
The image device, output frame rate and resolution of
the cameras are as follows:
XCD-V60/V60CR: 1/3-type PS IT CCD, 90 fps, VGA
XCD-SX90/SX90CR: 1/3-type PS IT CCD, 30 fps,
SXGA
XCD-U100/U100CR: 1/1.8-type PS IT CCD, 15 fps,
UXGA
Daisy chain connection
The camera is equipped with two IEEE1394b
connectors that support connection of multiple cameras.
As the power can be supplied from a 12-pin connector,
the camera achieves daisy chain connection without
limitation of power supply capacity so that a simple
image processing system with multiple cameras can be
developed.
Hardware preprocessing
The camera is equipped with hardware LUT (Lookup
Table).
The black and white models are also equipped with 3 ×
3 pixel matrix operation.
Bus synchronization
The cameras connected to the same bus automatically
operate in synchronization with the 1394 bus, without
using an external sync signal. The exposure timing on
multiple cameras is synchronized correctly via the
IEEE1394b cable only.
Broadcast delivery of commands
The camera settings for all the cameras connected to the
same bus can be changed at the same time. For example,
the gain or shutter speed is set to the same value on all
the cameras, or exposure starts on all the cameras
simultaneously using a software trigger.
Memory channel
The memory channel allows storage of up to 15 sets of
camera settings such as gain and shutter.
Bulk trigger mode
The Bulk trigger mode allows output of multiple images
with a shot of a trigger signal. Each image is shot with
the camera settings stored in the memory channel. Up to
15 image settings are possible.
Memory Shot
The image exposed from the sensor is stored in the
camera's built-in memory. The stored image can be read
out using a command from the host PC when required.

Partial scan
Partial scan clips a required angle of view (area) from
the entire screen to be read out. As a part of the image is
read out, the unit takes advantage of reduced image data
and high-speed transfer. The minimum clipping unit is
32 pixels × 24 lines.
Binning
Binning increases the sensitivity and frame rate based on
mixing the pixel data.
