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 electronic device comprising:
an acquisition unit that acquires image data in which a first person and a second person are imaged, the image data being generated by an imaging unit that comprises a plurality of pixels; and
a processor that obtains first height information on the first person and second height information on the second person based on the image data, and identifies the first person and the second person based on the first height information and the second height information.
2. The electronic device according to claim 1 , wherein
the processor determines a state of at least one of the first person and the second person based on the first height information and the second height information.
3. The electronic device according to claim 1 , wherein
when height information on the first person obtained after the first height information is obtained is less than predetermined height information, the processor determines that the first person is in an abnormal state.
4. The electronic device according to claim 1 , further comprising
an output unit that outputs information indicating that the first person is in an abnormal state when height information on the first person obtained after the first height information is obtained is less than predetermined height information.
5. The electronic device according to claim 1 , further comprising
an output unit that outputs information indicating an abnormality when at least one of the first person and the second person is in an abnormal state.
6. The electronic device according to claim 5 , wherein
the information indicating an abnormality is output by a speaker or a display.
7. The electronic device according to claim 1 , wherein
the image data is an image obtained when at least one of the first person and the second person moves from an imaging area to a non-imaging area.
8. The electronic device according to claim 1 , wherein the image data acquired by the acquisition unit is image data in which the first person and the second person are imaged from above the first person and the second person.
9. The electronic device according to claim 1 , wherein the processor corrects the first height information based on a positional relationship between an imaging unit and the first person and corrects the second height information based on a positional relationship between the imaging unit and the second person, and identifies the first person and the second person based on the corrected first height information and the corrected second height information.
10. The electronic device according to claim 1 , further comprising the imaging unit that, in addition to the plurality of pixels, comprises a lens system through which light reflected from the first person and the second person passes before reaching the plurality of pixels.
