Image acquisition method and system

Assim Boukhayma

A method of acquiring an image of a scene illuminated by a first beam, by means of a sensor including at least two pixels, including the steps of: a) for each pixel, reading a first output value of the pixel representative of the intensity of the radiation ...

The Gigavision Camera: A 2Mpixel Image Sensor with 0.56um2 1-T Digital Pixels

Edoardo Charbon, Hyungjune Yoon

We present a CMOS image sensor with deep-subwavelength, digital 1-T pixels designed for use in a digital film concept known as Gigavision (GV) camera. In GV, the levels of gray in the picture are derived from the concentration of activated pixels. Activate ...

Semiconductor Image Sensing

Peter Seitz, Nicolas Blanc

Silicon is an excellent detector material for electromagnetic radiation in the wavelength range of 0.1 to 1000 nm. In the visible spectral range (400-700 nm), external quantum efficiencies approaching 100% are obtained. When combined with the amazing minia ...
