Vehicle Lamp Image Splitting for Distortion-Free Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image distortion occurs when two lamps on a moving object, such as a vehicle, output a single image, particularly in the center portion due to overlapping areas, leading to incomplete or overlapped images.
Innovation Solution
A lamp system with a control unit that allocates and adjusts the first and second images to be output by the left and right lamps, respectively, by modifying the transparency and brightness of overlapping areas, ensuring the images are divided and output without distortion by adjusting the size and brightness of these areas based on the original image and distance between the lamps and the projection surface.

Engineering Contradiction Analysis
1Reliability
If both left and right lamps output one image together, then the lighting function is achieved, but image distortion occurs in the center portion due to overlapping areas
Solution Approach 1:
The patent divides the single image into two separate image portions, allocating the left portion to the left lamp and the right portion to the right lamp. This segmentation prevents the overlapping issue by ensuring each lamp outputs only its designated portion, thereby maintaining image integrity without center portion distortion.
Solution Approach 2:
The patent applies different transparency characteristics to different regions of the image. Specifically, the overlapping area (center portion) is assigned a transparency value between 0 and 1, while non-overlapping areas use a transparency value of 1. This local differentiation allows the overlapping region to blend smoothly, preventing visible distortion while maintaining overall image quality.
2Manufacturing precision
If the lamps divide the image in half and output separately, then image distortion is reduced, but the center portions may be empty or overlap due to image processing errors
Solution Approach 1:
The control unit performs preliminary processing to determine the overlapping area between the left and right image portions before the lamps output the images. By calculating and identifying the overlapping region in advance, the system can pre-assign appropriate transparency values, ensuring that even if alignment errors occur, the center portion will blend correctly rather than appearing empty or distorted.
Solution Approach 2:
The patent dynamically adjusts the transparency parameter of the overlapping area based on the calculated overlap between left and right image portions. By changing the transparency parameter (setting it between 0 and 1 for overlapping areas), the system compensates for image processing errors and ensures complete, distortion-free image output regardless of minor alignment variations.
3Reliability
If transparency of overlapping area is adjusted, then image distortion is prevented, but additional control complexity is required
Solution Approach 1:
The control unit automatically calculates the overlapping area between left and right image portions and self-adjusts the transparency parameters without requiring external intervention or complex external control systems. This self-service approach maintains high image quality while minimizing additional control complexity, as the existing control unit performs the additional calculations and adjustments.

AI summary
A lamp system capable of improving ease of use by outputting an image without distortion when one image is divided and output from the left and right lamps, respectively. The lamp system includes a left lamp installed on a left side of a moving object in one direction to output an allocated first image, a right lamp installed on a right side of the moving object in one direction to output an allocated second image, and a control unit receiving original image information from the outside to allocate the first image and the second image to the left lamp and the right lamp, respectively, based on the original image but change and allocate an overlapping area that is an overlapping portion of the first image and the second image.
