Head-Up Display Control for Action Support Image Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-up display systems struggle to maintain visibility of action support images, such as arrows, when the foreground color matches the image color, leading to confusion and difficulty in recognizing the image's meaning.
Innovation Solution
A display control device that retains the original color of the action support image while adding a contrasting color to its outer perimeter, ensuring high visibility and maintaining the image's meaning even when the foreground color is similar.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the display color of the action support image is changed to increase visibility, then the visibility is improved, but the original meaning of the image is lost
Solution Approach 1:
The action support image is divided into two distinct parts: the internal region retaining the original design color and the outer periphery region with a different color. This segmentation allows each part to serve different functions - the internal region preserves the original meaning while the outer region enhances visibility through color contrast with the foreground.
Solution Approach 2:
Different color properties are applied to different parts of the image. The internal region maintains its original color quality for meaning preservation, while the outer periphery region adopts a different color quality specifically for visibility enhancement. This local differentiation resolves the contradiction between maintaining original meaning and improving visibility.

If a contrasting color is applied to the entire image, then visibility is improved, but the design consistency is compromised
Solution Approach 1:
The image is segmented into internal and outer periphery regions, allowing the contrasting color to be applied only to the outer region while the internal region maintains its original design. This segmentation preserves design consistency in the core area while achieving visibility improvement through the outer contrasting border.
Solution Approach 2:
The contrasting color property is applied locally only to the outer periphery region rather than the entire image. This local application maintains design consistency in the internal region while providing visibility enhancement at the boundaries where it is most needed for differentiation from the foreground.

AI summary
A display control device includes an input unit receiving a recognition result of a surrounding situation of a vehicle; and control circuitry controlling an image generating device such that a predetermined image indicating a presentation image at the time of being displayed on a display medium transmitting light is generated in a case in which a predetermined target is recognized in the vicinity of the vehicle. The control circuitry senses, on the basis of the recognition result, that a color of a foreground of the vehicle on which the first presentation image is superimposed in the display medium is changed from a first color to a second color. Then, the controller generates a second predetermined image indicating a second presentation image by using the image generating device when the second color satisfies a predetermined condition with respect to a third color of at least a part of an outer peripheral region in the first presentation image. The second presentation image includes at least a region other than the outer peripheral region in the first presentation image, and a color of at least a part of an outer peripheral region in the second presentation image is a fourth color different from the third color.
