Abstract

The invention relates to an auto-focusing method and a module and an image pick-up device employing the method, which are applied to shooting films and taking pictures. The device comprises an image sensing module, an auto-focusing module and a display unit. The auto-focusing module is respectively coupled with the image sensing module and the display unit. When the image pick-up device receives an image, the user locks a target for the image and the auto-focusing module calculates size of the imaging scope according to size of the target in the image. The imaging scope is displayed in the display unit after digital zoom amplification for the user to view the taken picture. If the image pick-up device receives images continuously, the auto-focusing module senses the moving direction of the target in the imaging scope and adjusts the position of the imaging scope according to the moving direction of the target so as to ensure that the target is in the imaging scope.

Description

technical field [0001] The present invention relates to an image capture technology, especially an automatic focus method and module capable of adjusting the viewfinder range as the object moves, and an image capture device applying the method. Background technique [0002] Known shooting devices such as video recorders, cameras, or network cameras for computers can track the subject by the user directly driving the shooting device or moving the shooting device through a mechanical shaft when shooting dynamic images. However, the focus frame is The disadvantage of fixed range is that when the subject moves too fast or gets too close to the shooting device, the subject will leave the focus frame, causing the shooting effect not as expected by the user. [0003] Such as figure 1 As shown, the general shooting device 1 is mounted on the tripod 2, and the shooting direction of the shooting device 1 can be controlled through a control handle 3. The focus frame of the shooting de...
