Provided are a feature impression axis determination system, a feature impression axis determination method, and a program thereof capable of determining a feature axis indicating features of a plurality of images. A plurality of images is input, and a standard impression value of each of the plurality of images is determined with respect to at least two standard impression axes. The determined standard impression values are plotted in a standard impression region. In the standard region defined by the two standard impression axes, an axis on which a variance of the standard impression values becomes a maximum is determined as a feature impression axis indicating features of the plurality of input images. The determined feature impression axis is displayed in the standard region.
