A hazard detection system measures a color and intensity of a portion of an image of a scene. The image is obtained using a known gain and/or exposure such that the image substantially lacks any saturation. A black body brightness temperature and the corresponding block body intensity are determined based on the measured color. A hazard condition, such the presence of a flame, can be detected using a comparison of the measured intensity and the computed intensity. The gain and/or exposure can be selected such that only the pixels of intensity greater than a certain threshold generally saturate in the captured image. Hazard conditions, such as smoke, can be detected using images in which selective saturation is permitted.
