The XC-ST70 camera represents Sony's next generation of analog 2/3" black and white video cameras, ideal for image processing and machine vision applications. (The XC-ST70CE is the CCIR standard model.) The XC-ST70 is a compact, lightweight, black and white video camera incorporating the latest 2/3" Interline Transfer (IT) CCD with HAD technology providing 768 (H) x 494 (V) effective picture elements and incorporating a C-Mount type lens mount. The XC-ST70 is easy to use and its small size allows for flexible interface.
2/3" IT HAD CCD
All controls outside the camera
High Sensitivity: 0.3 lx (F1.4)
High S/N ratio: 60 dB
Simplified and more flexible trigger from previous models
Small, light weight, one piece camera
Excellent vibration and shock characteristics
Small and light weight power adaptor
The XC-ST70 uses the latest 2/3" Interline Transfer (IT) CCD with HAD technology which is more sensitive than the CCD used in the XC-77 camera family. These new CCDs have a microlens over each pixel to significantly improve the light collection efficiency. This is reflected in the minimum sensitivity specification of 0.3 lx. That means the camera should be able to detect more faint signals or need less gain with less noise when detecting faint signals.
The XC-ST70 has all the camera control switches accessible from the outside of the camera. There is no need for the user to open the camera to modify the operating mode of the camera or to determine or confirm switches settings. A user will no longer need to "customize" the internal camera switches.
The XC-ST70 has an improved trigger/shutter that significantly improves and simplifies the trigger operation from previous models. The various versions of Reset-Restart and Donpisha are now replaced with a simplified trigger/shutter that provides much greater functionality and flexibility. Now, the shutter speed of the external trigger shutter can be specified by the width of an external trigger pulse or switch setting in the rear panel. With this function, the XC-ST70 can take a clear image of a fast moving object.
The XC-ST70 is a small, lightweight one-piece camera very similar in size to the XC-73/75. The camera body's measurements are 29 x 44 mm (same as the XC-77/75/73); however, the length measures only 58 mm long, 46% shorter than the XC-77. The camera weighs only 105 grams, 45% lighter than the XC-77 at 190 grams. It even weighs less than the XC-73/75, 140 grams. The compact, lightweight camera body allows the camera to be used in very tight places and for some remote camera-head applications.
The XC-ST70 has improved vibration resistance. Vibration resistance has been improved to 10G over a wider vibration frequency range (20 to 200 Hz). The improvement in vibration resistance is achieved by improved board-to-board connections. The compact size and improved vibration resistance makes the XC-ST70 even more viable as a remote head camera replacement i.e. XC-77RR and XC-77BB. The XC-ST70 can resist up to a 70G shock.
The DC-700/700CE is a camera adapter for all current DC operated XC cameras. The DC700/700CE supplies 13V, 1.3A. It is smaller (110 x 53 x 160mm) and lighter (700g) than the DC-77RR and DC-777, and useful in space limited applications. The DC-700/700CE adopts the new pin assignment of 12pin connector, which is based upon EIAJ; therefore, it is different from current models such as DC-77RR and DC-777. Because the new camera adaptor has a protection circuit inside, all current XC models can work with the DC-700/700CE.
