Vehicular Vision Graphic Overlay Transparency Control

Solution Overview

Problem

Existing vehicle vision systems require large memory storage to accommodate numerous combinations of graphic overlays for different driving conditions, which increases costs and complexity.

Innovation Solution

The system controls the transparency of graphic overlays programmatically, allowing a single combination of overlays to be stored in memory, with transparency adjustments enabling only relevant overlays to be visible based on driving conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple combinations of graphic overlays are stored in memory for different driving conditions, then the system can display relevant information for each condition, but the memory size and system complexity increase

Engineering Contradiction:

Improvedisplay adaptabilityVSAvoidmemory size

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent merges all graphic overlay elements into a single composite overlay that contains all possible graphic elements. Instead of storing separate overlay combinations for different driving conditions, the system stores one comprehensive overlay and uses transparency control to show only relevant portions for each condition.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent changes the transparency parameter of different regions of the graphic overlay dynamically based on driving conditions. By adjusting transparency values programmatically, the system displays only the relevant graphic elements for the current condition while hiding others, eliminating the need to store multiple overlay versions.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If multiple combinations of graphic overlays are stored in memory for different driving conditions, then the system can display relevant information for each condition, but the system complexity and costs increase

Engineering Contradiction:

Improvedisplay adaptabilityVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges all graphic overlay elements into a single composite overlay that contains all possible graphic elements. Instead of storing separate overlay combinations for different driving conditions, the system stores one comprehensive overlay and uses transparency control to show only relevant portions for each condition.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single graphic overlay serves multiple functions by displaying different information for different driving conditions. The same overlay structure is reused across all conditions, with only the transparency parameters changing to adapt to different scenarios, reducing system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Loss of information

If all graphic overlay portions are displayed with full transparency, then all information is visible, but irrelevant information distracts the driver

Engineering Contradiction:

Improveinformation visibilityVSAvoiddriver distraction

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent applies different transparency qualities to different regions of the graphic overlay based on their relevance to the current driving condition. Relevant regions maintain full visibility while irrelevant regions are set to transparent or semi-transparent, eliminating driver distraction from unnecessary information.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The transparency of graphic overlay regions is dynamically adjusted based on the current driving condition. The system programmatically changes transparency values in real-time to match the active driving condition, ensuring only relevant information is displayed with appropriate visibility.

Inventive Principle:

Principle #15Dynamics

AI summary

A vehicular vision system includes a camera disposed at a vehicle, an electronic control unit, and a video display disposed in the vehicle. The system, responsive to processing of captured image data, displays video images on the video display. The system retrieves graphic overlay data from memory. The graphic overlay data represents a plurality of graphic overlay portions, with each graphic overlay portion being associated with a respective display portion of a plurality of display portions of the video display. Responsive to occurrence of a driving condition, the system retrieves graphic overlay data, displays the graphic overlay portions, and adjusts a transparency of one or more of the displayed graphic overlay portions such that at least one displayed graphic overlay portion is viewable by the driver and at least one other displayed graphic overlay portion is not viewable by the driver.
