To determine the state of a subject person with a simple structure, an image determining device includes: an imaging unit that captures an image from a first direction, the image including the subject person; a first detector that detects size information from the image, the size information being about the subject person in the first direction; a second detector that detects position-related information, the position-related information being different from the information detected by the first detector; and a determining unit that determines the state of the subject person, based on a result of the detection performed by the first detector and a result of the detection performed by the second detector.

Image determining device to determine the state of a subject

To appropriately guide a subject person while protecting a privacy of the subject person despite use of an captured image of the subject person, a guidance system includes: an image capturing unit capable of capturing an image containing a subject person from a first direction; a detection unit that detects a size of an image of the subject person from the image captured by the image capturing unit; and a guidance unit that provides guidance for the subject person based on a detection result of the detection unit.
