Solution Overview

Problem

Ordinary camera users experience poor video capturing effects due to camera shaking when moving the lens, which affects the dynamic effects of videos.

Innovation Solution

A method that processes videos by changing the image display mode, including zoom factor, display range, and rotation angle of image frames to simulate moving capturing effects without actual camera movement, using a device with a processor and memory to collect and generate new videos.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If ordinary users move the lens for capturing videos to enhance dynamic effects, then the video becomes more dynamic, but camera shaking occurs and deteriorates the capturing quality

Engineering Contradiction:

Improvedynamic effectsVSAvoidcapturing quality

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

Instead of moving the camera to achieve dynamic effects, the patent inverts the approach by keeping the camera stationary and moving the display frame through image processing. The display frame moves along a predetermined curve on the image frame to simulate camera movement effects while eliminating actual camera shaking.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent replaces the mechanical system of physically moving the camera with an image processing system. By processing image frames to move the display frame along a curve, the system achieves dynamic effects without mechanical camera movement, thereby avoiding camera shaking.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If the camera is kept stationary to avoid shaking, then capturing quality improves, but dynamic effects are lost

Engineering Contradiction:

Improvecapturing qualityVSAvoiddynamic effects

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent introduces dynamics into the image processing system by moving the display frame along a predetermined curve through the image frame. This dynamic display frame movement simulates camera motion effects while the camera remains stationary, achieving both stability and dynamic effects.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent adds a new dimension of display frame movement along a curve in the image space, rather than physical camera movement in real space. This dimensional transformation allows dynamic effects to be achieved through image processing while maintaining camera stability.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A method for processing videos includes: N videos are collected, wherein N is a positive integer larger than or equal to 1; at least one image frame in the N videos is selected, an image display mode of the selected at least one image frame is changed and image display data is obtained, wherein the image display data is a part of data included in the image frame; and a new video is generated by using the image display data of selected at least one image frame of which image display mode is changed. As such, the video capturing effect is less affected by moving the camera during capturing, and dynamic effects of moving capturing can be realized.
