Photographic system and operation method thereof
A photographic system for photographing a warm-blooded animal in a background is provided, including an infrared sensor, a host, and a camera module. The infrared sensor is configured to identify the position of the warm-blooded animal in the background, and generate position data according to the position. The host is coupled to the infrared sensor, and configured to receive the position data and generate at least one parameter according to the position data. The camera module is coupled to the host, and includes a camera and a controller. The controller is configured to receive the parameter and adjust the photographing direction of the camera according to the parameter.
1 . An operation method of a photographing system, comprising:
providing the photographing system, wherein the photographing system comprises an infrared sensor, a host, and a camera module, and the host is coupled to the infrared sensor and the camera module;
adjusting a center of a field of view of the infrared sensor and a center of a field of view of the camera module to the same coordinate;
using the infrared sensor to identify that whether a heating object is existed in a background;
using the infrared sensor to determine that whether the heating object is a target object to be photographed;
using the infrared sensor to generate a position data when the target object is in the background and transmit the position data to the host;
using the host to generate at least one parameter according to the position data and transmit the at least one parameter to a controller of the camera module;
using the controller to adjust a camera of the camera module to align a field of view of the camera to the target object; and
using the camera to focus and photograph.
2 . The operation method as claimed in claim 1 , wherein the photographic system further comprises an environment light sensor, and the operation method further comprises:
before the step of using the infrared sensor to identify that whether the heating object is existed in the background, using the environment light sensor to detect a lightness of the background.
3 . The operation method as claimed in claim 2 , wherein the camera comprises a visible spectrum camera and a near-infrared camera, wherein when the light detected by the environment light sensor is sufficient, the host chooses the visible spectrum camera to photograph, wherein when the light detected by the environment light sensor is insufficient, the host chooses the near-infrared camera to photograph.
4 . The operation method as claimed in claim 1 , wherein the at least one parameter includes an orientation angle, an elevation angle, a dip angle, or a combination thereof.
