How to... Image in Extreme, Low-Light Conditions


Imaging in extremely low-light conditions can present a challenge for a variety of tasks, including military, biomedical, scientific, non-destructive testing, underwater research, realism broadcast TV and mine and safety inspection. Clear, full color, full motion images in extreme low-light condition requires an imaging tool that offers sensitivity and dynamic range in excess of current generation night vision cameras.

Toshiba Imaging Systems Division, a division of Toshiba America, has developed an ultra-sensitive ˝" CCD color camera with the help of new, revolutionary electron multiplying technology, making it 1,000 times more sensitive than a conventional color CCD. The incoming signal is multiplied by a factor of one thousand, allowing a minimum illumination with full color reproduction down to 0.25 mlux (1/1000 lux) in color at 50 IRE. With a high resolution 658 x 496 pixel sensor and a built-in electronic shutter to 1/2000 seconds, the IK-1000ME offers a real solution for imaging in ultra-low-light or starlight conditions.

The challenge of low-light imaging was brought to the company’s attention by customers who required small, reasonably priced, compact cameras that could reproduce color images in starlight, underwater and other low-light conditions. In answer to these custom requests, Toshiba designed the compact, [58 mm (W) x 58.4 mm (H) x 133 mm (D)] ultra-sensitive IK-1000ME color camera.
