Scallop's Novel Color Filters Improve Low-Light Imaging

via Image Sensors World by Vladimir Koifman on 2/2/12

Scallop Imaging, a division of Tenebraex, presents "Gemini Technology: Color imaging under all lighting conditions, including extreme low light". The company says "we have developed a new system of producing color video imagery in low light that offers an order of magnitude better low light performance compared to standard RGB sensors.

Instead of the standard RGB three-filter set, our Gemini system uses unique high transmission color filters to produce a full color image from two channels under all lighting conditions, including extreme low light".

Not much more info is given. A 121MB video file from 1.2MP monochrome CMOS sensor (3.75 µm pixel) equipped with Gemini color filters compares to the color version of the same image sensor.

A video frame recorded at 0.18 lux (equivalent to 3/4 moon), 15 fps taken with a color 1.2 megapixel image sensor.

A Gemini prototype video frame taken with the same exposure and frame rate as above, with monochrome 1.2 Mpixel image sensors equipped with Gemini color filters.
