Fishing reel, information processing device, and fishing information processing system

A fishing information processing system, comprising:

• a fishing reel comprising:
• a throwing detection unit configured to detect a throwing start and a throwing end,
• a drag release amount detection unit that detects a drag release amount, and
• a handle rotation detection unit that detects a number of rotations of a handle of the fishing reel, and
• an information processing device comprising:
• a line length calculation unit that calculates a line length of a released fishing line, wherein
• the line length calculation unit calculates the line length of the fishing line:
• on a basis of the number of rotations of the handle by the handle rotation detection unit from the throwing start to the throwing end, and
• by subtracting a difference based on the drag release amount from the line length of the fishing line based on the number of rotations of the handle.

An information processing device, comprising:

• a reception unit that receives information from a device external to the information processing device, and
• a line length calculation unit that calculates a line length of a fishing line, wherein:
• the reception unit receives information of a throwing start, information of a throwing end, information of a drag release amount, and information of a number of rotations of a handle of a fishing reel from the external device, and
• the line length calculation unit calculates the line length of the fishing line:
• on a basis of the number of rotations of the handle from the throwing start to the throwing end, and
• by subtracting a difference based on the drag release amount from the line length of the fishing line based on the number of rotations of the handle.
