Projection Control Using Timed Image Segmentation for Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in achieving high accuracy projection and imaging, especially in circumstances where the distance between the projection apparatus and the projection destination is long, or when the projection surface is bright, or when there is significant movement or noise, leading to image deterioration.
Innovation Solution
A control device and method that acquires and projects multiple images forming an information image at different timings, using a processor to control a projection apparatus, which includes switching between first and second control modes based on distance and using color differentiation and alignment marks to ensure accurate projection and imaging.

Engineering Contradiction Analysis
1Area of stationary object
If the distance between the projection apparatus and the projection destination is long, then the projection area can be larger, but the image quality and accuracy deteriorate
Solution Approach 1:
The information image is divided into multiple separate images that are projected at different timings. By segmenting the original image into multiple parts and projecting them sequentially rather than all at once, the system maintains image quality even at long distances while still covering a large projection area.
Solution Approach 2:
The projection is performed periodically by projecting multiple images at different timings rather than simultaneously. This periodic projection approach allows each individual image to be projected with sufficient intensity and focus for high quality, while the sequence of projections covers the entire information image across the large projection area.
2Adaptability or versatility
If the projection surface is bright, then the projection can be performed in more environments, but the image accuracy deteriorates
Solution Approach 1:
The information image is segmented into multiple images projected at different timings. This segmentation allows each individual projection to be optimized for accuracy by controlling projection parameters such as intensity and timing, while the system as a whole adapts to bright environments by using the multi-image approach that can compensate for environmental challenges.
Solution Approach 2:
The projection parameters are changed and optimized for each individual image projection. By adjusting parameters such as projection timing, intensity, and duration for each separate image, the system maintains high image accuracy even in bright environments, while the ability to modify these parameters provides adaptability to various environmental conditions.
3Productivity
If there is significant movement or noise during projection, then the projection can be performed more quickly, but the image quality deteriorates
Solution Approach 1:
The information image is divided into multiple images that are projected at different timings. This segmentation enables the system to project each image quickly and sequentially, maintaining high projection speed while reducing the exposure time for each individual projection, thereby minimizing the impact of movement and noise on image quality.
Solution Approach 2:
The multiple images are projected in continuous sequence without interruption. This continuous projection approach maintains high productivity by eliminating idle time between projections, while the rapid sequential timing ensures that movement and noise do not significantly affect each individual image projection, thus preserving image quality.
