Abstract
The invention discloses a method for realizing real-time shooting of a dynamic special-effect photo, which can automatically apply a real-time dynamic visual effect to a shot scene in the conventional shooting of a mobile phone camera and shoot a dynamic good photo of a mobile phone camera motion subject. The method has the main purposes that through real-time front and back scene dynamic blurring processing, even a common mobile phone camera user photographer who does not use a slow door to follow a shooting technique can easily and freely shoot a dynamic motion picture, and dynamic rendering visual effects are applied to a view-finding picture based on view finding, so that the photographer can intuitively preview and adjust the dynamic effect of the picture on a view-finding screen before shooting, and can directly obtain a live-shot picture with the dynamic effect without post processing after shooting.
Description
Technical Field
The invention relates to the field of intelligent shooting of mobile phone cameras Ai, in particular to a method for realizing real-time shooting of dynamic special effect pictures.
Background
In photography, if a motion picture rich in motion is to be captured, a shooting method using a relatively low shutter speed and following is required.
However, even an experienced photographer does not always obtain a successful dynamic picture every time when using such a shooting technique for slow-motion tracking.
For a common mobile phone user, it is more difficult to capture a motion picture with a mobile phone camera.
Disclosure of Invention
The invention mainly solves the technical problem of providing a method for realizing real-time shooting of a dynamic special-effect photo, which can automatically apply a real-time dynamic visual effect to a shot scene in the conventional mobile phone camera shooting process and shoot a dynamic good photo of a mobile phone camera motion subject.
In order to solve the technical problems, the invention adopts a technical scheme that: a method for realizing real-time shooting of dynamic special effect pictures is characterized in that a main body in a current shot motion scene is isolated from a foreground and a background, and real-time dynamic blurring processing is carried out on the foreground and the background while the main body is kept clear and stable.
The invention has the following effective effects: through real-time front and back scene dynamic blurring processing, even a common mobile phone camera user photographer who does not use a slow gate to follow a shooting technique can easily and freely shoot a dynamic motion picture, and dynamic rendering visual effects are applied to a view-finding picture based on view finding, the photographer can intuitively preview and adjust the dynamic effect of the picture on a view-finding screen before shooting, and a real shot picture with the dynamic effect can be directly obtained without post processing after shooting.

FIG. 2 is a schematic diagram illustrating comparison of effects before and after real-time dynamic rendering when shooting a skiing sport scene according to an implementation method of shooting a dynamic special effect photo in real time of the present invention;
the parts in the drawings are numbered as follows: A. a moving subject; B. a dynamic blurred background picture; C. a view finding picture of conventional skiing sports without dynamic effect; D. and starting the skiing movement view-finding picture rendered by the real-time dynamic special effect.
Detailed Description
The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the invention easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the invention.
Referring to fig. 1, an embodiment of the present invention includes an implementation method for shooting a special motion effect photo in real time, which can automatically apply a real-time motion visual effect to a shot scene in a conventional mobile phone camera shooting process, so as to shoot a good motion subject photo of a mobile phone camera with rich motion, and implement real-time motion blur processing on front and back scene pictures while keeping a main body clear and stable in a current shot motion scene in a manner of isolating the main body from the front and back scenes.
The specific implementation mode is as follows:
step 1, automatically starting a motion scene shooting mode (dynamic special effect) through manual or intelligent recognition;
step 2, manually carrying out visual inspection or intelligently identifying the motion track of the main body A, determining the motion direction and judging the motion speed;
step 3, manually or intelligently setting the fuzzy direction and the fuzzy strength of the background B;
step 4, a real-time dynamic background motion special effect preview picture appears in the view-finding frame;
and 5, after determining the appropriate dynamic effect and picture composition, pressing a shutter to shoot, and storing the dynamic special effect picture.
Referring to fig. 2, an embodiment of real-time dynamic rendering when shooting a skiing scene according to the present invention:
step 1, setting a matched transverse dynamic fuzzy mode according to the gliding direction of a snowboarder in a viewing picture C;
step 2, setting a matched dynamic ambiguity according to the gliding speed of the snowboarder in the view-finding picture C;
and 3, rendering a single-board skiing view finding preview picture D rich in dynamic sense in real time.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
