The invention relates to a bolometer element, a bolometer cell, a bolometer camera, and a method for reading a bolometer cell. The bolometer cell comprises several bolometer elements. Each bolometer element comprises a first bolometer having a first heating resistance for sensing radiation power acting on the element, and a second bolometer having a second heating resistance, and in each bolometer element the first and second bolometers are electrically connected to each other in such a way that the heating resistance (611) of the first bolometer can be biased with the aid of a voltage through the heating resistance of the second bolometer in order to amplify the radiation power detected with the aid of the connection. With the aid of the invention, it is possible to implement an extremely sensitive bolometer camera.
