Periphery Image Display Transition for Intuitive In-Cabin Viewpoints

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users of periphery-image display devices for vehicles face difficulty in intuitively understanding the view point from which periphery images are displayed, especially when switching to vehicle-inside view points, as the transition can be abrupt and unclear.

Innovation Solution

The periphery-image display device includes a synthetic-image formation unit that forms vehicle-inside view point images by projecting camera images onto a virtual projection surface and a display control unit that temporarily displays interior-added images with gradually increasing transparency before showing the vehicle-inside view point image, allowing users to recognize the view point more intuitively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If periphery images are displayed from arbitrary virtual view points, then the information about vehicle periphery is improved, but the ease of understanding the view point deteriorates

Engineering Contradiction:

Improveinformation about vehicle peripheryVSAvoidease of understanding view point

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The system performs preliminary action by temporarily displaying interior-added images that show interior members before fully transitioning to vehicle-inside view point images. This preparatory display helps users anticipate and understand the upcoming view point change, making the transition more intuitive and reducing confusion about the arbitrary virtual view points.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The interior-added images serve as an intermediary between the exterior view and the vehicle-inside view. By temporarily displaying images that include both exterior periphery information and interior member references, the system creates a transitional medium that helps users understand and orient themselves during view point transitions.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If vehicle-inside view point images are displayed directly, then the productivity of information display is improved, but the ease of operation deteriorates due to abrupt transitions

Engineering Contradiction:

Improveproductivity of information displayVSAvoidease of understanding view point transition

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

Before displaying the vehicle-inside view point image, the system temporarily displays interior-added images that include interior members. This preliminary action prepares users for the view point transition, making the subsequent direct display of vehicle-inside views more acceptable and understandable, thus maintaining productivity while improving ease of operation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system applies dynamics by controlling the display timing and transparency of interior-added images. The interior members are temporarily displayed with gradually increasing transparency before the vehicle-inside view point image, creating a dynamic transition that adapts to user perception needs while maintaining efficient information delivery.

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If interior-added images with gradual transparency are displayed, then the ease of operation is improved, but the loss of time increases

Engineering Contradiction:

Improveease of understanding view pointVSAvoidtime for display transition

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system applies partial action by temporarily displaying only the necessary interior members (instrument panel, seats, steering wheel) with gradual transparency rather than fully opaque images. This partial display provides sufficient contextual information for users to understand the view point transition without requiring excessive time, balancing ease of operation with time efficiency.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A synthetic-image formation unit forms a vehicle-inside view point image showing a periphery of a vehicle in such a way as to transparently pass through a portion or an entirety of the vehicle and taken from a vehicle-inside view point inside a vehicle room. The synthetic-image formation unit further forms an interior-added image including an image of an interior member viewed from the vehicle-inside view point using pre-stored data for drawing an image of the interior member. A display control unit temporarily displays the interior-added image and displays animation which gradually raises a transparency of the image of the interior member, before displaying the vehicle-inside view point image, when changing over a display screen of the display to the vehicle-inside view point image in response to a user's manipulation on the vehicle.
