Image determining device to determine the state of a subject
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.
1. An imaging device comprising:
an imaging sensor that, when at least one of a first person and a second person moves from an imaging area of the imaging sensor to a non-imaging area of the imaging sensor, captures image data including the first person, the second person, and an object;
a processor configured to:
acquire height information about the first person and height information about the second person based on the object included in the image data; and
identify the first person and the second person based on the height information about the first person and the height information about the second person; and
an output unit that outputs information indicating abnormality when at least one of the first person and the second person is in an abnormal state.
2. The imaging device of claim 1 , wherein
the processor determines a state of at least one of the first person and the second person based on the height information about the first person and the height information about the second person.
3. The imaging device of claim 1 , wherein
the imaging sensor images the heads of the first person and the second person.
4. The imaging device of claim 1 , wherein
the processor acquires respective heights of the first person and the second person as the height information.
5. The imaging device of claim 1 , wherein
the imaging sensor simultaneously images the first person and the second person.
6. The imaging device of claim 1 , wherein
the imaging sensor images the first person and the second person when the first person and the second person are in the same posture.
7. The imaging device of claim 1 , wherein
the information indicating abnormality is image data including the one of the first person and the second person who is in an abnormal state.
8. The imaging device of claim 7 , wherein
the image data including the one who is in an abnormal state is displayed on a display.
9. The imaging device of claim 1 , wherein
the information indicating abnormality is output by way of a speaker.
10. An imaging device comprising:
a lens;
an imaging sensor that, when at least one of a first person and a second person moves from an imaging area of the imaging sensor to a non-imaging area of the imaging sensor, captures image data including the first person, the second person, and an object based on light through the lens; and
a processor configured to:
acquire height information about the first person and height information about the second person based on the object included in the image data;
identify the first person and the second person based on the height information about the first person and the height information about the second person; and
output information indicating abnormality when at least one of the first person and the second person is in an abnormal state.
11. The imaging device of claim 10 , wherein
the information indicating abnormality is output by way of a speaker.
