Problems solved by technology

However, sensor sensing can easily lead to misjudgment. Under the induction of gravity sensor or acceleration sensor, electronic equipment that moves slowly and uniformly or moves up and down will be misjudged as stationary and fail to focus in time. It is misjudged that the camera object has been changed, which leads to unnecessary repeated focusing and delays in shooting time

Embodiment Construction

[0017] Such as figure 1 As shown, the present invention proposes a dynamic focusing method without a sensor, and its focus lies in: an electronic device with a camera function, the electronic device is extended with an application program, and the application program includes a camera image acquisition module, an image matching module, an image Similarity analysis and judgment module;

[0018] A kind of dynamic focus method step without sensor of the present invention is:

[0019] The camera acquisition image module acquires pre-processed images;

[0020] The image matching module matches the image collected this time with the image collected last time, and searches for similar feature points;

[0021] The image similarity analysis and judgment module analyzes several similar feature points to determine whether the camera moves, and sends an instruction whether to perform focusing according to whether the camera moves;

[0022] The image acquisition module of the camera aut...

Abstract

The invention discloses a dynamic focusing method without a sensor. According to the dynamic focusing method, electronic equipment with a camera shooting function is provided; an application program is mounted on the electronic equipment in an extending manner; the application program comprises a camera acquisition image module, an image matching module, and an image similarity analyzing and judging module. With the adoption of the method and the equipment, a user can judge without the help of the sensor in a camera shooting focusing process and automatic and intelligent focusing can be rapidly and accurately realized; the practicability is stronger and the applicable range is wider.

Description

technical field [0001] The invention relates to a dynamic focusing method without a sensor. Background technique [0002] The shooting functions of electronic devices (such as mobile phones, tablet computers, learning machines, etc.) need to judge whether to refocus according to whether the user changes the camera object or moves the camera. And the judging method of whether this needs refocusing, existing electronic equipment all is to realize with the help of sensor. However, sensor sensing can easily lead to misjudgment. Under the induction of gravity sensor or acceleration sensor, electronic equipment that moves slowly and uniformly or moves up and down will be misjudged as stationary and fail to focus in time. It is misjudged that the camera object has been changed, which leads to unnecessary repeated focusing and delays in shooting time. Contents of the invention [0003] In view of this, the technical problem solved by the present invention is to provide a dynamic...
