Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing technologies require high processing capacity to superimpose computer-generated images naturally onto real-space images, making it difficult to achieve natural appearances on devices with limited processing capacity, such as mobile terminals.
Innovation Solution
An image processing device and method that selects a removal region from an image based on distance information, specifies a complementary region from the image's background, and superimposes a complementary image generated from this region to enhance the natural appearance of the image by reducing processing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If computer-generated images are superimposed on real-space images to achieve natural appearance, then image quality and naturalness are improved, but processing capacity requirements increase significantly
Solution Approach 1:
The patent segments the image processing task into distinct components: removing the object to be erased, generating a complementary image from the background region, and superimposing the complementary image. This segmentation allows each processing stage to be optimized independently, reducing the overall computational burden while maintaining natural appearance.
Solution Approach 2:
The patent performs preliminary actions by first removing the object to be erased and generating the complementary image before final superimposition. The complementary image is generated in advance from the background region, which simplifies the final composition step and reduces real-time processing requirements.
2Manufacturing precision
If complex image processing is performed to achieve natural superimposition, then image quality is improved, but device complexity increases
Solution Approach 1:
The processing system is segmented into functional modules: an object removal unit, a complementary image generation unit, and a superimposition unit. Each module performs a specific function, making the overall complex task manageable through modular design and reducing system integration complexity.
Solution Approach 2:
The patent creates a copy of the background region to generate the complementary image. This copying approach allows the system to work with replicated data rather than repeatedly accessing and processing the original complex scene, reducing computational complexity while maintaining image fidelity.
3Manufacturing precision
If object removal and complementary image generation are performed accurately, then image naturalness is improved, but calculation requirements increase
Solution Approach 1:
The patent extracts the background region surrounding the object to be erased and uses it to generate the complementary image. By taking out only the necessary background portions rather than processing the entire image, the calculation energy required is significantly reduced while maintaining accurate region selection.
Solution Approach 2:
The patent applies local quality processing by focusing computational resources on the specific regions that matter: the object boundary area and the immediate background surrounding it. Rather than uniformly processing the entire image, the system concentrates calculations on local areas that contribute most to natural appearance.

AI summary
The present disclosure relates to an image processing device, an imaging device, and an image processing method to superimpose a complementary image in such a manner that an appearance becomes more natural. From an image acquired by imaging of an arbitrary subject, a removal region selecting unit selects a region, in which an intended object to be removed is included, as a removal region with reference to distance information that is acquired when the image is imaged and that indicates a distance to the subject. Based on the distance information, a complementary region specifying unit specifies a complementary region to complement the removal region from a region including a background of the object to be removed in the image. An image superimposition processing unit superimposes a complementary image generated from the complementary region on a place from which the removal region is deleted in the image.
