Fuji Film widens dynamic range of CCD sensorYoshiko Hara
Dynamic Range (DR) is the range of exposure, i.e., scene brightness, over which a camera responds with good contrast and good Signal-to-Noise Ratio (SNR). This is a scene-dependent image quality factor that incorporates sensor sensitivity, noise, and stray light. High Dynamic Range (HDR)...
The dynamic range of charge coupled devices (CCD) is studied by an example of type TCD1304AP detectors in atomic-emission spectrometers. For this we have used an instrument developed by us with original methods for measuring the sensor temperature and analyzing nonlinear distortions at different ...

Here we exploit photothermal-induced phase change in a gas-filled hollow-core photonic bandgap fibre, and demonstrate an all-fibre acetylene gas sensor with a noise equivalent concentration of 2 p.p.b. (2.3 × 10−9 cm−1 in absorption coefficient) and an unprecedented dynamic range ...
A neutral-density filter (ND filter) is usually made of glass. It attaches to your camera lens and lessens the amount of light that passes through it. With less light coming in, you can adjust the shutter speed to lengthen exposure time or raise the camera’s image sensor or widen the ...
there are many examples where the dynamic range of a sensor may not be large enough. A common example is what happens when a camera flash lights up a nearby face. This will usually either result in an over-exposed face, or under-exposed background. For robots and vehicles many other exam...
DYNAMIC SENSOR RANGE United States Patent Application 20110257936 Kind Code: A1 Abstract: A device for sensing a phenomenon using a dynamic measurement range includes: a sensing element configured to measure the phenomenon using a first measurement range and to provide an analog indication of a value...
