Smart Device Moving Image Playback Region Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional smart device applications do not allow for flexible positioning and sizing of multiple moving images on a single screen, limiting the ability to compare and analyze multiple moving images simultaneously, such as news broadcasts, which requires multiple devices for real-time viewing.
Innovation Solution
A method for moving and resizing multiple moving images on a smart device by generating a second movable display view within a first display view, allowing users to change the position and size of moving images using touch operations with one or two fingers, enabling simultaneous playback and sound switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple moving images are played back simultaneously on a single smart device, then the ability to compare and analyze multiple moving images is improved, but the device complexity and operation difficulty increase
Solution Approach 1:
The display screen is segmented into multiple independent playback regions, each capable of displaying and playing back a different moving image. Users can independently position and size each playback region, enabling flexible comparison of multiple moving images without increasing overall system complexity.
Solution Approach 2:
The patent introduces spatial arrangement dimensions (position and size) for playback regions on the screen. By allowing playback regions to be positioned at different locations and scaled to different sizes, the system enables multiple moving images to coexist in a two-dimensional space, transforming a single-point playback into a multi-point spatial distribution.
2Adaptability or versatility
If the position and size of moving images can be freely adjusted, then user flexibility is improved, but the ease of operation deteriorates
Solution Approach 1:
The playback regions are designed to be dynamically adjustable rather than fixed. Users can freely change the position and size of each playback region according to their needs, and the system responds in real-time to these adjustments, maintaining operational simplicity despite the flexibility provided.
3Productivity
If multiple moving images are displayed at different positions and sizes, then real-time comparison capability is improved, but the difficulty of detecting and measuring positions increases
Solution Approach 1:
Each playback region maintains its own independent properties (position, size) that can be individually detected and measured. The system handles each region's coordinates and dimensions separately, simplifying the detection and measurement process for each individual region while enabling comprehensive multi-region comparison capabilities.

AI summary
Provided is a moving image playback method, a moving image playback device, and a computer readable storage medium which stores a moving image playback program which enable a plurality of moving images to be played back simultaneously on a single smart device, and enable the plurality of moving images to be moved and magnified/reduced within the smart device screen. For example, a moving image playback device of the present invention includes an operation part that performs an operation related to playback of a moving image; a control part that controls a request from the operation part; and a display part that displays the moving image according to the control of the control part. The control part generates a first moving image display view which is a movable region of a moving image to be projected in the display part; generates a second moving image display view which enables the moving image to be moved on the first moving image display view; plays back the moving image on the second moving image display view; obtains, on the basis of coordinates of the four corners of the second moving image display view, a pre-movement position of the moving image selected via the operation part; calculates a post-movement position of the moving image that was moved via the operation part by reflecting an amount of movement of the moving image on the coordinates of the four corners of the second moving image display view; and displays the moving image at the post-movement position.
