1. An information processing device comprising: a feature amount extraction unit configured to extract each feature amount from a connected image generated by connecting images photographed from different viewpoints; and a specific object recognition unit configured to perform a process of determining a position of a specific object based on the feature amount extracted by the feature amount extraction unit, wherein the feature amount extraction unit performs a feature amount extraction process to which a separated filter in which filter-formed regions are set to be separated is applied, wherein the feature amount extraction unit calculates the feature amount as an index value used to distinguish a first state in which a finger, which is the specific object, comes into contact with a board from a second state in which the finger does not come into contact with the board, wherein based on the feature amount extracted by the feature amount extraction unit, the specific object recognition unit performs a process of determining whether the finger which is the specific object comes into contact with the board, and wherein the feature amount extraction unit and the specific object recognition unit are each implemented via at least one processor.
