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 first image data in which a subject person is imaged, the first image data being generated by an imaging unit that comprises a plurality of pixels;
a processor programmed to:
detect information about a size of the subject person based on the first image data;
determine a state of the subject person based on the detected information about the size; and
set a first criteria according to which information to be transmitted to an external device is limited and a second criteria according to which the information to be transmitted to the external device is not limited; and
a communication unit that communicates with the external device according to the first criteria or the second criteria when the state of the subject person is determined to be abnormal.
2. The electronic device according to claim 1 , wherein the communication unit does not transmit the first image data to the external device when the first criteria is set.
3. The electronic device according to claim 1 , wherein the communication unit transmits the first image data to the external device when the second criteria is set.
4. The electronic device according to claim 1 , wherein the communication unit transmits second image data to the external device, the second image data being obtained by performing masking processing on the first image data.
5. The electronic device according to claim 1 , wherein the acquisition unit acquires third image data captured by changing an imaging condition when the state of the subject person cannot be determined to be normal.
6. The electronic device according to claim 1 , wherein the processor is programmed to determine the state of the subject person based on a size of a head of the subject person.
7. The electronic device according to claim 6 , wherein the processor is programmed to determine that the state of the subject person is abnormal when the size of the head of the subject person is smaller than a predetermined size.
8. The electronic device according to claim 1 , wherein the first image data is image data of the subject person captured from above.
9. The electronic device according to claim 1 , wherein the communication unit transmits information indicating that there is no problem when the state of the subject person is determined to be normal.
10. The electronic device according to claim 1 , further comprising an output unit that outputs information indicating an abnormal state when the state of the subject person is abnormal.
11. The electronic device according to claim 10 , wherein the information indicating the abnormal state is output by a speaker or a display.
