Method and device for automatically adjusting focal distance

The embodiment of the invention provides a method and device for automatically adjusting focal distance. The method comprises the following steps: performing the first focusing on a lens of a shooting device according to a shooting starting instruction and determining an initial-set focal distance; receiving a shooting instruction and recording shooting jitter data of the shooting device when receiving the shooting instruction, and then determining the fine-set focal distance according to the initial-set focal distance, the shooting jitter data and the preset focal distance setting numerical table; finally performing the second focusing on the shooting focal distance by using the fine-set focal distance and performing the shooting. Since the second focusing is performed according to the jitter of a user after the user presses down a photographing button, the focal distance deviation caused by the jitter when pressing down the photographing button is reduced, and the sharpness of a shot picture is improved. Since the fine-set focal distance is determined according to the initial-set focal distance, the shooting jitter data and the preset focal distance setting numerical table before performing the second focusing, and the second focusing and the shooting are performed by taking the fine-set focal distance as the shooting focal distance, the focus setting time is reduced, and the photographing speed is improved.

Low-power-consumption wireless photographing access and transmission method

The invention discloses a low-power-consumption wireless photographing access and transmission method, and the method comprises the following steps that a low-power-consumption camera transmits a network access application to a concentrator, and the concentrator records the field intensity values of all signals transmitted by the low-power-consumption camera to form a field intensity record table;the server reads the field intensity record tables of all the concentrators at set intervals, judges whether the low-power-consumption camera in the field intensity record chart is allocated to the concentrator for management or not; if the low-power-consumption cameras are not allocated, the low-power-consumption cameras are allocated to the proper concentrators according to a camera address allocation algorithm, and then the low-power-consumption camera addresses are issued to the corresponding concentrators by the server by using a camera allocation command; and when the concentrator receives a network access application of the low-power-consumption camera managed by the concentrator, the low-power-consumption camera is configured to enter a network of the concentrator, and the low-power-consumption camera can execute a photographing task only after accessing a certain concentrator. According to the invention, the camera is low in power consumption and cost and high in transmissionrate.

A method and device for automatically adjusting focus

Embodiments of the present invention provide a method and device for automatically adjusting focus, including: focusing a lens of a photographing device for the first time according to a photographing start instruction and determining an initial focal length. Receive the shooting instruction and record the shooting shake data of the shooting device when receiving the shooting instruction, and then determine the fine adjustment focus according to the initial focus adjustment, the shooting shake data and the preset focus adjustment value table. Finally, use the fine-tuning focal length as the shooting focal length to focus and shoot for the second time. After the user presses the camera button, the second focus is performed according to the shaking of the user, thereby reducing the focus shift caused by the shaking when the camera button is pressed, and improving the clarity of the photographed photos. Because before the second focusing, the fine-tuning focal length is determined according to the initial focal length, shooting shake data and the preset focal length adjustment value table, and then the fine-tuning focal length is used as the shooting focal length for the second focusing and shooting, thereby reducing The time for focusing is shortened, and the speed of taking pictures is improved.
