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.

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

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 
(EIAJ), 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.

The camera is equipped with hardware LUT (Lookup 
Table).
The black and white models are also equipped with 3 × 
3 pixel matrix operation.

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.

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.

The memory channel allows storage of up to 15 sets of 
camera settings such as gain and shutter.

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.

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 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 increases the sensitivity and frame rate based on 
mixing the pixel data.
