Selection of an evaluation index based upon statistical values of respective evaluation indices is disclosed. In one example, an information processing apparatus comprises an evaluation index unit that determines a plurality of evaluation indices on a basis of imaging data obtained by imaging a subject, wherein the evaluation indices are respectively based upon different wavelength component combinations of the imaging data. An evaluation value unit determines an evaluation value based on a statistical value of each of the evaluation indices, for each of the evaluation indices. A selection unit then determines a selected evaluation index from the evaluation indices on a basis of the evaluation values.

Provided is a grain gloss measurement apparatus capable of accurately measuring gloss of grain. A grain gloss measurement apparatus includes a light source to emit light to a measurement region for grain in an oblique direction, a light receiver to receive the light reflected from the measurement region, and a gloss value calculation device to calculate a gloss value of the grain based on the reflected light received by the light receiver. The light source includes a first light source to emit light to the measurement region from one side and a second light source to emit light from another side that is opposite to the first light source across the measurement region. The light emitted from the first light source and the light emitted from the second light source have different wavelengths. The light receiver is disposed on the same side as the second light source, and the gloss value calculation device includes an image processing unit to identify a grain zone in the measurement region based on the light of the second light source that is reflected off the grain and received by the light receiver.
