Overview 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 (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. 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.

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. 9-pin connector with fixing screws Low power consumption, vibrationresistant structure, and compact size IIDC Ver.1.31 protocol compliant 3
