Vehicle Peripheral Observation Device with Nested Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle peripheral observation systems, it is difficult for drivers to accurately distinguish which area is enlarged when part of the overhead image is displayed on a monitor, leading to accidental operations and increased time to correct them.
Innovation Solution
A system using multiple cameras and an image processor to generate overhead images, with an enlarged display unit that creates intermediate images between the indicated area and the enlarged area, ensuring the indicated area is included in the next intermediate image, allowing for sequential zooming and accurate recognition of the enlarged area, which can be manually or automatically indicated, including by detecting obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an overhead image is divided into multiple areas and one area is enlarged and displayed, then the driver can observe detailed information of a specific area, but it becomes difficult to distinguish which region the enlarged image corresponds to
Solution Approach 1:
The patent embeds a small indicator image showing the enlarged area's position within the overhead image into the corner of the enlarged display. This nested visual cue allows the driver to understand the spatial relationship between the enlarged view and the overall scene, resolving the contradiction between detailed observation and spatial context preservation
Solution Approach 2:
The indicator image acts as an intermediary element that bridges the enlarged area and the original overhead image. It provides a visual reference that helps the driver understand which area is currently enlarged, maintaining spatial relationship information while enabling detailed area observation
2Ease of operation
If a small area is indicated and enlarged, then detailed information is visible, but accidental operations may occur and take time to notice and correct
Solution Approach 1:
The indicator image provides immediate visual feedback about which area is enlarged, allowing the driver to quickly notice if an accidental operation occurred. This feedback mechanism reduces correction time by enabling rapid detection and recovery from accidental selections
Solution Approach 2:
The indicator image uses visual differentiation (potentially including color or brightness changes) to clearly mark the enlarged area, making it easily distinguishable from other areas. This enhances operation accuracy by preventing accidental selections and enables quick detection of unintended operations

AI summary
Provided is a device whereby it is possible to accurately recognize which area has been enlarged when part of an overhead image displayed on a monitor is displayed as enlarged. When any one area of a plurality divided areas (D1-D4) is indicated, the divided areas being a result of dividing an overhead image displayed on a monitor (21), an image of the indicated divided area (D1-D4) is set as an image to be enlarged, and an auxiliary display area (21B) is set as an enlarged display area. Enlarged display unit forms a plurality of intermediate images (M) of an intermediate size between the size of the indicated divided area (D2) and the size of the enlarged display area, and the intermediate images are sequentially displayed beginning with the smallest intermediate image (M), using the indicated divided area (D2) as an origin point.
