Smartphone Camera Moving-Perspective Video Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Built-in cameras of smartphones have fixed shooting angles, making it cumbersome to produce videos with a moving-perspective effect without external devices or post-production.
Innovation Solution
An image capturing method that captures multiple images within a smaller capture frame within the camera's field of view and moves the frame to a perspective target, generating a moving-perspective video without requiring the phone to be moved or post-production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-perspective camera is used, then the device structure is simple, but the video perspective cannot be moved
Solution Approach 1:
The patent applies dynamics by making the capture frame movable within the fixed FOV. Instead of physically moving the camera, the capture frame dynamically shifts to different positions and orientations within the captured image area, allowing the video perspective to change while keeping the camera module structure fixed and simple.
Solution Approach 2:
The patent transitions from physical spatial movement (moving the entire camera) to digital dimension movement (shifting the capture frame within the image). This dimensional change allows perspective movement capability to be achieved through software-based frame repositioning rather than hardware movement, resolving the contradiction between adaptability and device complexity.
2Ease of operation
If external devices or post-production are used to achieve moving-perspective effect, then the video effect can be improved, but the operation process becomes cumbersome
Solution Approach 1:
The system performs self-service by automatically capturing multiple images at different capture frames and generating the moving-perspective video directly within the device. This eliminates the need for external devices or post-production processing, allowing users to record convenient moving-perspective videos directly through the camera application.
Solution Approach 2:
The patent applies preliminary action by capturing multiple images at different capture frames within the FOV before video generation. These pre-captured images are then used to construct the moving-perspective video, eliminating the need for post-production work and improving video production efficiency.
3Productivity
If multiple images are captured at different capture frames, then moving-perspective video can be generated, but the capturing time increases
Solution Approach 1:
The patent applies periodic action by capturing multiple images at different capture frames in sequence. The capture frame moves to different positions and orientations periodically, capturing necessary images at each position, then synthesizing these periodically captured images into a moving-perspective video, balancing video generation capability with capturing time.

AI summary
An image capturing method, applicable to an electronic device including an image capturing device and a processor, is provided. The image capturing device has a field of view (FOV). The image capturing method includes: capturing a plurality of images of the FOV by using the image capturing device, and recording a plurality of images within a capture frame in the FOV from the images, where a capturing range of the capture frame is smaller than or equal to the FOV; moving the capture frame to a perspective-moving target within the FOV in response to a setting operation on the perspective-moving target; and generating a moving-perspective video from the recorded images.
