Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D image processing technologies often result in printed images that differ from the expected output due to parallax adjustments, leading to missing areas in the final print.
Innovation Solution
An image processing apparatus and method that allows users to specify an indispensable output area within a 3D image synthesis, using a monitor, input device, and control unit to ensure accurate inclusion of desired areas, with features like parallax map generation and human figure detection to prevent areas out of mergence from being included.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If parallax adjustment is performed to enhance 3D image depth, then the stereoscopic impression is improved, but the printable area may be reduced causing expected output areas to be missing
Solution Approach 1:
The system performs preliminary determination of the indispensable output area before parallax adjustment. The control unit identifies which areas must be preserved in the final print, then uses this information to constrain the parallax adjustment range, ensuring that depth enhancement does not cause these critical areas to fall outside the printable region.
Solution Approach 2:
The system changes the parallax parameter within a constrained range determined by the indispensable output area. By adjusting the parallax amount while maintaining the inclusion of critical areas, the system optimizes 3D depth perception without sacrificing the printable area needed for expected output.
2Reliability
If the distance between lenses is increased to enhance 3D image depth, then the stereoscopic effect is improved, but the areas out of mergence increase causing parts of the image to become undisplayable
Solution Approach 1:
The system takes preliminary anti-action by identifying areas out of mergence and using this information to prevent excessive parallax adjustment. The control unit calculates the potential loss areas and constrains the lens distance or parallax adjustment to prevent these areas from becoming undisplayable, thus protecting the completeness of the final image.
Solution Approach 2:
The system uses feedback from the determination of indispensable output areas and areas out of mergence to adjust the parallax settings. The control unit continuously monitors whether the current parallax adjustment would cause critical areas to be lost, and adjusts the parameters accordingly to maintain both stereoscopic effect and image completeness.
3Manufacturing precision
If manual parallax adjustment is performed to optimize 3D depth, then the image quality is improved, but the process becomes more complex and time-consuming
Solution Approach 1:
The system performs self-service by automatically determining the indispensable output area and calculating the appropriate parallax adjustment parameters. The control unit autonomously identifies critical areas, computes the optimal parallax amount that preserves these areas while enhancing 3D depth, and applies the adjustment without requiring complex manual intervention, thus simplifying the process while maintaining high image quality.

AI summary
An image processing apparatus includes a monitor that displays an image based on a right viewpoint image and left viewpoint image, or multi-viewpoint images. The displayed image is used by a user for specifying an indispensable output area which the user wants to be included in a 3D image. The apparatus further includes an input device inputting information on the indispensable output area as specified by the user referring to the image as displayed on the monitor, a control unit causing the indispensable output area to be indicated in the image, and an output device outputting the right viewpoint image and left viewpoint image, or multi-viewpoint images, and information on the indispensable output area.
