PROBLEM TO BE SOLVED: To provide a visual stimulation presentation apparatus which has high accuracy in measuring the color matching function and is inexpensive and compact.SOLUTION: The visual stimulation presentation apparatus includes a light source part 1 which has internally an element light source array having a plurality of element light sources different in an emission color and emits a luminous flux in which the light emitted from the element light source array is mixed almost uniformly, an optical path selection part 2 which enables alternate switching presentation of at least a part of the luminous flux radiated from the light source part 1, in a first area and a second area in a visual field of a subject, and a control part 3 which synchronizes the light source part 1 and the optical path selection part 2 and presents, in the first area, the luminous flux emitted from a first element light source group composed of a plurality of predetermined element light sources among the element light sources included in the element light source array, while enabling presentation, in the second area, of the light flux emitted from a second element light source group composed of a plurality of predetermined element light sources among the element light sources included in the element light source array. In the second element light source group, one or a plurality of element light sources not included in the first element light source group and the element light sources included in the first element light source group, are included.COPYRIGHT: (C)2013,JPO&INPIT【課題】等色関数の測定精度が高く、安価でコンパクトな視覚刺激呈示装置を提供する。【解決手段】発光色の異なる複数の素光源を有する素光源アレイを内部に有し当該素光源アレイから発光された光が略均一に混合された光束を発する光源部1と、光源部1から放射された光束の少なくとも一部を被験者の視野内の第1の領域と第2の領域に交互に切り替えて呈示可能とする光路選択部2と、光源部1と光路選択部2を同期させて第1の領域に対して素光源アレイに含まれる素光源のうち予め定めた複数の素光源からなる第1の素光源群より発光された光束を呈示し、第2の領域に対して前記素光源アレイに含まれる素光源のうち予め定めた複数の素光源からなる第2の素光源群より発光された光束を呈示可能とする制御部3を有している。第2の素光源群には、第1の素光源群に含まれない1または複数の素光源と第1の素光源群に含まれる素光源とが含まれている。【選択図】図1
