1. A sensor array (1) for recording a color image in a visible spectrum (8) and a hyperspectral image, the sensor array comprising:
an image sensor (2) having a plurality of photocells (3), the photocells (3) are assigned at least in part respectively a color filter (4), the photocells (3) are grouped in subcells (5) and the subcells (5) are grouped in supercells (6), wherein there are a plurality of the color channels (7,R,G,B,A,C), which together cover the entire visible spectrum (8) and wherein each said subcell (5) has at least one of the color filters (4) for each color channel in the plurality of color channels (7,R,G,B,A,C), and characteristic wavelengths (9) of the color filters (4) belonging to at least one said color channel (7,R,G,B,A,C), in each case at least partly differ from one another between the subcells (5) of a supercell (6).
