Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing in-vehicle display systems face challenges in synchronously changing the colors of multiple images displayed on a single screen, leading to timing discrepancies that create a sense of incongruity for the user, especially when images from different devices are synthesized.

Innovation Solution

An in-vehicle display control device with an image acquisition unit, a change information acquisition unit, and an image synthesizing unit that generates a synthetic image by incorporating a color change layer based on acquired color change information, allowing simultaneous color adjustment of multiple element images without individually changing their colors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If color changes are performed by different devices for different element images, then each device can independently control its own image, but the timing of color changes becomes unsynchronized across the synthetic image

Engineering Contradiction:

ImproveIndependent color control of element imagesVSAvoidSynchronization of color change timing

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent introduces a color change layer as an intermediary element that mediates between multiple image generation devices and the final synthetic image. Instead of having each device independently change colors (which causes timing issues), the color change layer receives color change instructions and applies them uniformly across the entire synthetic image, ensuring synchronized color changes while maintaining the ability to display multiple element images from different sources

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If multiple image generation devices generate images independently, then device functionality is maintained, but color change timing becomes inconsistent across the synthetic image

Engineering Contradiction:

ImproveIndependent image generation by multiple devicesVSAvoidConsistency of color change timing

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent merges the color change function into a single unified layer that combines the output of multiple independent image generation devices. The color change layer integrates color change instructions and applies them to the entire synthetic image simultaneously, thereby maintaining the independence of individual image generation devices while ensuring consistent and reliable color change timing across the complete display

Inventive Principle:

Principle #5Merging (Combining)

AI summary

An in-vehicle display control device includes: an image acquisition unit that acquires a plurality of element images to be displayed on a vehicular display from each image generation unit; a change information acquisition unit that acquires color change information; and an image synthesizing unit that generates a synthetic image based on a color in the color change information and the plurality of element images. The image synthesizing unit generates the synthetic image by synthesizing the plurality of element images and a color change layer.
