Digital multispectral camera system with at least two independent digital cameras

摘要

A digital camera system having at least two independent digital cameras, which capture image signals in different narrow-band spectral ranges, wherein each of the at least two independent digital cameras comprises at least one separate two-dimensional digital image sensor, preferably a CCD sensor or a CMOS sensor, and at least one filter element corresponding to the particular narrow-band spectral range connected upstream of the at least one two-dimensional digital image sensor and having at least one filter region. The at least one color filter element additionally comprises at least one neutral region, which is translucent in a spectral range that includes at least the different narrow-band spectral ranges of the at least two independent digital cameras, in particular in a panchromatic spectral range, and which is assigned to at least one specific neutral, in particular unused, pixel region of the associated at least one two-dimensional digital image sensor.
