An information processing device includes a categorizing section and a display control section. The categorizing section extracts a material component image identified as a material component from plural images obtained by imaging a sample fluid containing plural types of material element, and categorizes the extracted material component image serving as a detected component by predetermined category. The display control section performs control to re-categorize a material component image serving as the detected component already categorized into a different category, such that, when selection of a movement destination category is received in a state in which a first image list of detected components is being displayed, in a subsequent state in which the first image list and a second image list for the movement destination are being displayed at the same time, a material component image selected from the first image list is moved to the second image list.
