•Datasheet: IK-1000ME Extreme Low Light Color Video Camera

This imaging system features Toshiba's new, proprietary electron-multiplying CCD technology, making it ideal for all ultra low-light applications. 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.

Toshiba's electron multiplying technology results in a super-sensitive camera that is 1000 times more sensitive than a conventional color CCD. The ½ inch CCD features a high resolution 658 x 496 pixel sensor, a built-in electronic shutter to 1/2000 sec. and accepts C-mount lenses. Developed in response to customer requests for a camera that could reproduce color images in starlight, underwater and other lowlight conditions, the compact, ultra-sensitive color camera measures 58 mm (W) x 58.4 mm (H) x 133 mm (D).

Light Shot Noise
Light shot noise is induced by the fact that light has fluctuations and the numbers of incoming light photons into photo diode during one charge storage vary even while light intensity (power) is constant. SQRT of Ns (= number of incoming light photons into photo diode becomes light shot noise Nn.

Conventional CCD camera Light shot noise is negligible.
Conventional CCD of low years without "Charge multiplication" has very little dark current shot noise. Also their circuitry suppresses the FD reset noise. Thus, the dominant factor of noise is the FD Amp noise. However, as the performance of MOS transistor in FD Amp evolves going forward, light shot noise can be more outstanding, depending on the image-shooting conditions.
