SPECTRAL DATA PROCESSING APPARATUS AND SPECTRAL DATA PROCESSING METHOD

摘要

A spectral data processing apparatus where a particular spectrum is displayed on a display based on 3D spectral data having time, signal intensities, and a prescribed parameter, comprising: a 2D spectrum calculating unit compiling the signal intensities for each point in time and calculating 2D spectrum of the signal intensities and the prescribed parameter, based on the spectral data; a signal-intensity-time change calculating unit calculating change in signal intensity over time for each value of the prescribed parameter, based on the spectral data; and a display controlling unit displaying, on the display, the 2D spectrum and the change in the signal intensity over time in superimposed manner using multicolor, light and shading, or change in brightness, so that the change in signal intensity over time is displayed to match the prescribed parameter of the 2D spectrum and the time changes along the axis of signal intensities of the 2D spectrum.
