DFW-X700

OUTLINE

The DFW-SX900/X700 is a C-mounted color digital video camera utilizing a 1/2-type PS IT CCD. The IEEE1394-1995 digital interface realizes a transfer speed of 400M bps and outputs of SXGA (1,280 × 960)/YUV (4 : 2 : 2)/7.5 fps with the DFW-SX900, XGA (1,024 × 768)/YUV (4 : 2 : 2)/15 fps with the DFW-X700. In addition, the DFW-SX900/X700 also adopts a primary color filter CCD to realize good color reproductivity, as well as a square pixel CCD to eliminate the need for aspect ratio conversion in the image processor.

MAIN FEATURES

1/2-type progressive scan IT CCD

Primary color filter/square pixel/progressive scan CCD

Non-compressed YUV (4 : 2 : 2) 8 bits each

External trigger function

The external trigger shutter function allows the image exposure to be coordinated with external equipment and moving objects. The exposure time can be controlled via software over the IEEE1394 bus.

Solid aluminum diecasting chassis

Partial scan/output of images is possible by the partial scan function
