Solution Overview
Problem
Existing image processing technologies lack convenience in managing the disposition of projection surfaces and projection apparatuses, particularly in accurately determining and adjusting the position and size of virtual projection surfaces and apparatuses within physical spaces for optimal image projection.
Innovation Solution
An image processing apparatus and method that acquires image data of a space, generates virtual projection surface and apparatus data based on position and normal vector data, and overlays these virtual elements onto the image data to provide a visual representation for user convenience in planning and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If virtual projection surfaces and apparatuses are manually configured without visual feedback, then setup time is reduced, but positioning accuracy and user convenience deteriorate
Solution Approach 1:
The patent creates virtual copies of projection surfaces and apparatuses that are superimposed on captured images of the physical space. These virtual elements replicate the actual projection geometry and can be visually adjusted, allowing users to plan and verify projections before physical setup, thereby improving positioning accuracy without extending setup time
Solution Approach 2:
The patent introduces an image processing apparatus as an intermediary that captures real-space images, generates corresponding virtual images with projection elements, and displays them for user review. This intermediary system bridges the gap between physical setup and visual verification, enabling accurate positioning through digital preview
2Adaptability or versatility
If complex manual adjustment of projection parameters is required, then projection flexibility is improved, but ease of operation deteriorates
Solution Approach 1:
The patent enables the system to automatically generate virtual projection surfaces and apparatuses based on captured images and pre-stored projection information. The system self-configures the virtual environment without requiring manual parameter adjustment, maintaining projection flexibility while dramatically improving ease of operation through automated setup
Solution Approach 2:
The patent performs preliminary generation of virtual projection elements and superimposition on captured images before actual projection setup. By pre-visualizing the projection configuration and allowing user verification in the virtual environment, complex adjustments are resolved in advance, making the actual operation simple and convenient
3Manufacturing precision
If detailed projection planning is performed without visual representation, then setup accuracy is improved, but device complexity increases
Solution Approach 1:
The patent creates simplified virtual copies of the physical projection environment that can be displayed on standard imaging devices. These virtual representations capture essential projection geometry without requiring complex specialized hardware, achieving high setup accuracy through accessible digital visualization
Solution Approach 2:
The image processing apparatus serves as an intermediary that handles the complexity of generating and managing virtual projection elements, while presenting a simple visual interface to users. This mediator absorbs the system complexity internally while maintaining user-friendly operation and high setup accuracy

AI summary
An image processing apparatus includes a processor configured to: acquire first image data obtained by imaging a space with an imaging apparatus; generate first virtual projection surface data representing a first virtual projection surface and first virtual projection apparatus data representing a first virtual projection apparatus, based on first position data representing a first position in the space and first normal vector data representing a first normal vector of a first surface corresponding to an object present at the first position in the space; generate second image data representing a second image in which the first virtual projection surface and the first virtual projection apparatus are displayed on a first image represented by the first image data, based on the first image data, the first virtual projection surface data, and the first virtual projection apparatus data; and output the second image data to an output destination.
