In a device for processing imaging-analysis data, two kinds of imaging-analysis data are stored in a storage section 21: (a) first imaging-analysis data, in which measurement data of a target substance, acquired by performing a first predetermined analysis at each of a plurality of measurement points within an analysis target area of a sample S, is associated with spatial position information of the measurement point, and (b) second imaging-analysis data, in which measurement data of a reference substance, acquired by performing a second predetermined analysis at each of the measurement points, is associated with spatial position information of the measurement point. A normalization executer 28 normalizes the measurement data of the target substance at each measurement point, based on the measurement data of the reference substance acquired at the same measurement point.
