Abstract
The invention relates to an image acquisition device comprising a sensor composed of an array of photosensitive pixels, and an array of elementary filters covering the sensor. Pixels may be of three different types: panchromatic pixels, primary colour pixels and infrared pixels. Under low illumination conditions, the device displays a monochrome image using panchromatic pixels, and under high illumination conditions, a colour image with a high signal to noise ratio, by combining primary colour images and subtracting the infrared image.
