The MMX InfraRed Spectrometer (MIRS) is an imaging spectrometer on board of MMX JAXA mission. MIRS is built at LESIA-Paris Observatory in collaboration with four other French laboratories, collaboration and financial support of CNES and close collaboration with JAXA and MELCO. The instrument is designed to fully accomplish MMX's scientific and measurement objectives. MIRS will remotely provide near-infrared spectral maps of Phobos and Deimos containing compositional diagnostic spectral features that will be used to analyze the surface composition and to support the sampling site selection. MIRS will also study Mars atmosphere, in particular to spatial and temporal changes such as clouds, dust and water vapor.

The present invention detects the luminance level of light having an intensity exceeding the saturation level of an image sensor. Provided is a method that can be used for detecting the luminance level of light from a high-luminance light source. The method comprises: a step for receiving light from a first light emitting element by means of an image sensor; a step for detecting, in a light reception region in which the light from the first light emitting element has been received, a first saturation region in which the amount of the received light is greater than a saturation level of the image sensor; and a step for determining the size of the first saturation region as a first detection value that represents the luminance level of the light from the first light emitting element.
