Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Generating depth information for converting 2D images to 3D images is time-consuming and not cost-efficient.
Innovation Solution
An apparatus and method that utilize a user interface to input guide information, such as dots, lines, or diagrams, to generate depth information efficiently, including a depth information generator that automatically generates and adjusts depth values based on user input, allowing for faster and more cost-effective conversion of 2D images to 3D.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If depth information is generated for all frames of a 2D image to convert to 3D, then complete 3D conversion is achieved, but processing time increases greatly and cost-efficiency deteriorates
Solution Approach 1:
The patent segments the 2D image into multiple frames and selectively processes only certain key frames to generate depth information, rather than processing every frame. This segmentation approach reduces the total number of frames requiring depth generation, thereby improving processing efficiency and reducing time loss while still achieving effective 3D conversion.
Solution Approach 2:
The patent applies partial action by generating depth information for only a subset of frames rather than all frames. By selecting specific frames (e.g., key frames or frames with significant visual changes) for depth generation, the system achieves adequate 3D conversion效果 with reduced computational burden and time consumption.
2Reliability
If traditional methods are used to generate depth information for all frames, then comprehensive 3D depth data is obtained, but processing cost increases and efficiency decreases
Solution Approach 1:
The patent divides the image sequence into multiple frames and applies depth generation only to selected segments (frames), maintaining high depth information quality for those segments while improving overall processing productivity through selective rather than exhaustive processing.
Solution Approach 2:
The patent changes the processing parameter from 'all frames' to 'selected frames', adjusting the scope of depth generation to optimize the balance between depth information quality and processing productivity. This parameter change enables faster processing while maintaining sufficient 3D conversion quality.

AI summary
An apparatus for generating depth information includes: a receiver which receives a two-dimensional (2D) image signal including a plurality of frames; a user input unit; a user interface (UI) generator which generates a tool UI to input guide information for generating depth information; a display unit which displays a frame for which depth information is generated among the plurality of frames, and the generated tool UI; and a depth information generator which generates depth information corresponding to the guide information input by the user input unit through the tool UI.
