摘要： The present application provides an image capture method and an image capture device. The image capture method is applied to the image capture device, which comprises a first chip, zoom lenses, image sensors, zoom motors, and focus motors. The number of the first chip is one; and the number of the zoom lenses are two, comprising a first short zoom lens and a second long zoom lens, wherein the two zoom lenses have different zoom ranges, and there is an overlap range between the zoom ranges of the two zoom lenses. The number of the image sensors is two, and the two image sensors correspond to the two zoom lenses respectively, and the two image sensors are communicatively connected to the first chip respectively. The number of the zoom motors is two, the number of the focus motors is two, and the two zoom motors and the two focus motors are communicatively connected to the first chip respectively. By using the superposition of the zoom ranges of the two zoom lenses, the focal length range of the image capture device is expanded without increasing the size of a single lens.

摘要： Embodiments of the present application provide an automatic focusing method and a PTZ camera. The method is applicable to the PTZ camera and comprises: calculating a current target object distance from a lens of the PTZ camera to a monitored target monitoring plane based on a pre-established spatial object distance parameter; wherein, the spatial object distance parameter contains a spatial plane equation of a reference monitoring plane; the reference monitoring plane is an equivalent plane of the target monitoring plane; searching in a preset relation table based on the current target object distance, a current magnification of the PTZ camera, determining a position information corresponding to a focus motor of the PTZ camera, the preset relation table including the relationship of the object distance, the magnification and the position information of the focus motor, and driving the focus motor to a position corresponding to the determined position information. Embodiments of the present application are applied to realize fast automatic focusing of the PTZ camera.

摘要： The present application discloses a variable magnification method, apparatus and a computer-readable storage medium, which belong to the technical field of monitoring technology. The method comprises: acquiring angle parameters for the current position of a camera after receiving a variable magnification instruction; wherein, the variable magnification instruction is configured for instructing the camera to perform the variable magnification based on a target magnification ratio parameter; querying target historical focusing information based on the angle parameters for the current position, wherein, the target historical focusing information comprises a historical magnification ratio parameter and a historical in-focus parameter of the camera; querying a target variable magnification curve based on the historical magnification ratio parameter and the historical in-focus parameter; and controlling the camera to perform the variable magnification based on the target variable magnification curve. The technical solution provided by the embodiments of the present application can avoid the phenomenon that the camera blurs pictures in the process of the variable magnification to a certain extent.
