In-Vehicle Camera Viewpoint Transition via Intermediate Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle camera systems experience disruptions in visual field when switching between different viewpoint displays, leading to a loss of visual field sense, especially during maneuvers like parking, due to sudden changes in viewpoint and the insertion of invalid black images during transitions.
Innovation Solution
An image processing device and method that generates intermediate viewpoint images to smoothly transition between first and second viewpoint images, ensuring continuous and seamless changes in the visual line and viewpoint, preventing the loss of visual field sense by performing viewpoint transformation and display control using a camera system with a display processing unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If viewpoint transformation is performed by switching between different view displays, then the driver can obtain different visual perspectives, but the visual field sense is lost due to sudden viewpoint changes and black image insertion
Solution Approach 1:
The viewpoint transformation is segmented into multiple intermediate stages rather than a single abrupt change. The system divides the transition from first viewpoint to second viewpoint into multiple incremental steps, generating intermediate viewpoint images that bridge the gap between different visual perspectives, thereby maintaining visual field continuity while providing viewpoint variation
Solution Approach 2:
Intermediate viewpoint images serve as mediators between the first and second viewpoint images. These intermediate images act as a bridge that smoothly transitions the visual field from one perspective to another, preventing the loss of visual field sense that occurs with direct viewpoint switching
2Ease of operation
If view display switching is performed using user operation as trigger, then the operation is simplified, but the transition causes black image insertion and visual information loss
Solution Approach 1:
The system performs preliminary generation of intermediate viewpoint images before the actual viewpoint switching occurs. By pre-calculating and preparing the intermediate visual states, the system ensures that no black images or visual gaps appear during the transition, maintaining continuous visual information while still responding to simple user operations
Solution Approach 2:
The viewpoint transformation maintains continuous display of useful visual information throughout the transition. Instead of inserting black images during switching, the system continuously generates and displays intermediate viewpoint images, ensuring that the visual field remains informative and useful throughout the entire transformation process

AI summary
An image processing device includes a viewpoint transformation and image generation unit that performs viewpoint transformation processing on an image. The viewpoint transformation and image generation unit is configured to: generate a first viewpoint image by the viewpoint transformation processing on an input image; generate, before generating a second viewpoint image in which a viewpoint and a visual line are different from those of the first viewpoint image, one or more intermediate viewpoint images in which a viewpoint and a visual line are intermediate between those of the first viewpoint image and those of the second viewpoint image; and generate the second viewpoint image.
