INFORMATION PROCESSING SYSTEM, INFORMATION PROCESSING APPARATUS, AND INFORMATION PROCESSING METHOD

The invention reduces data. An information processing system according to an embodiment includes: an excitation light source (100) that irradiates a corresponding plurality of samples belonging to a sample group with excitation light; a measurement unit (142) that measures fluorescence generated by irradiating the sample with the excitation light; and an information processing unit (2) that generates difference data on the basis of the difference between similar fluorescence signals among the fluorescence signals of the fluorescence measured for each sample. 本发明减少数据。根据实施方式的信息处理系统包括：激发光源(100)，用激发光照射属于样本组的相应的多个样本；测量单元(142)，测量通过用激发光照射样本产生的荧光；以及信息处理单元(2)，基于针对各个样本测量的荧光的荧光信号之中相似的荧光信号之间的差值产生差分数据。
