STH-DCSG

STH-DCSG Features

• Maximum resolution: 640H x 480V pixels
• Color and monochrome versions
• Global shutter - all pixels exposed at the same time
• Simultaneous exposure and readout
• Direct digital information from the imagers, bypasses analog noise and frame grabber jitter
• Conforms to Digital Camera Specification version 1.30.
• Single-cable interface for power, data, and control
• Synced imagers expose corresponding pixels at exactly the same time
• External synchronization - all STH-DCSG devices on the same IEEE 1394 bus are synchronized to capture images simultaneously
• Subsampling modes (binning and subwindow) for smaller frame sizes, faster frame rates, lower noise
• Electronic gain and exposure
• All modes fully under user control via the IEEE 1394 bus
• Milled solid aluminum alloy body for extreme rigidity
• Accepts standard C/CS-mount lenses

STH-DCSG Kit Contents

• STH-DCSG stereo head, color or monochrome
• 3.0 mm miniature 12 mm diameter lenses standard; other lenses available as options
• Small Vision System stereo analysis software for MS Windows 2000/XP or Linux 2.4/2.6
• 2 meter IEEE 1394 6-pin to 6-pin cable
• Hardware and Software Manuals

STH-DCSG Requirements

• Pentium-compatible PC (Pentium PIII/clone or better) running MS Windows 2000/XP or Linux 2.4/2.6 kernel 
• IEEE 1394 PCI or PCMCIA card*. IEEE 1394 card must supply 1.5W of power through the 6-pin cable.  Most PCI cards do this. PCMCIA cards must have a separate transformer power input.

* Items are available from Videre Design, see Ordering
