The monitoring camera is capable of performing artificial intelligence, and includes a capturing unit configured to capture an image of the imaging area, a detection unit configured to detect a person in the captured image of the imaging area based on the artificial intelligence, and a controller configured to determine a position of a face of the person in the captured image and determines a camera parameter of the monitoring camera based on a brightness or a moving speed of the face.
1. A monitoring camera capable of performing artificial intelligence, the monitoring camera comprising:
an image sensor configured to capture an image of an imaging area;
a detector configured to detect a person in the captured image of the imaging area based on the artificial intelligence; and
a controller configured to determine a position of a face of the person in the captured image and selectively determine a camera parameter of the monitoring camera based on either or both of a brightness or a moving speed of the face.
2. The monitoring camera according to claim 1 ,
wherein the controller sets the camera parameter.
3. The monitoring camera according to claim 1 ,
wherein when the person in the captured image is not detected, the controller determines and sets the camera parameter so that the detector detects the person in the captured image captured by the image sensor.
4. The monitoring camera according to claim 1 ,
wherein the camera parameter is exposure time of the image sensor, and
wherein the controller determines the exposure time so that the detector detects the face of the person in the captured image captured by the image sensor.
5. The monitoring camera according to claim 1 ,
wherein the camera parameter is a gain of the image sensor, and
wherein the controller determines the gain so that the detector detects the face of the person in the captured image captured by the image sensor.
6. The monitoring camera according to claim 1 ,
wherein the camera parameter is a rotation amount of at least one of pan rotation and tilt rotation of the image sensor, and
wherein the controller determines the rotation amount so that the detector detects the face of the person in the captured image captured by the image sensor.
7. The monitoring camera according to claim 1 ,
wherein the camera parameter is a zoom magnification of the image sensor, and
wherein the controller determines the zoom magnification so that the detector detects the face of the person in the captured image captured by the image sensor.
8. A monitoring camera capable of performing artificial intelligence, the monitoring camera comprising:
an image sensor configured to capture an image of an imaging area;
a detector configured to detect a person in the captured image of the imaging area based on the artificial intelligence; and
a controller configured to determine a position of a face of the person in the captured image and determine a camera parameter of the monitoring camera based on a brightness or a moving speed of the face,
wherein the camera parameter is a tone curve used to generate the captured image, and
wherein the controller determines the tone curve so that the detector detects the face of the person in the captured image captured by the image sensor.
