Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stereoscopic image display devices suffer from image distortion due to lenses slanted at an angle, which affects the clarity and reliability of three-dimensional image output.
Innovation Solution
A display device with a lens array where the lenses are slanted at an acute angle relative to the pixel arrangement, combined with a main controller that corrects pixel data units to compensate for distortion, using an edge detector and correction ranges to enhance image clarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If lenses are slanted at an acute angle relative to pixel arrangement to enable three-dimensional image display, then stereoscopic effect is achieved, but image distortion occurs
Solution Approach 1:
The system performs preliminary correction on pixel data before display by detecting edges in the input image and adjusting pixel values in advance. This preliminary action compensates for the distortion that will be introduced by the slanted lenses, ensuring that the final displayed image appears undistorted to viewers.
Solution Approach 2:
The distortion correction mechanism applies an anti-action by intentionally distorting the pixel data in the opposite direction of the expected lens-induced distortion. This preliminary anti-action counterbalances the harmful distortion effect, allowing the slanted lenses to function while maintaining image quality.
2Measurement precision
If pixel data correction is applied to compensate for lens distortion, then image clarity is improved, but processing complexity increases
Solution Approach 1:
The correction system applies local quality by focusing computational resources only on edge regions of the image where distortion is most perceptible. By detecting edges and applying correction primarily to pixels near detected edges rather than uniformly across the entire image, the system improves clarity where it matters most while reducing overall processing complexity.
Solution Approach 2:
The system uses edge detection to create a simplified representation (copy) of the image structure, then applies correction based on this copied edge map rather than processing all pixel data. This approach reduces processing complexity by working with a derived edge representation instead of the full high-resolution image data.

Function Achieved in This Case
The solution enables the display of a three-dimensional image with improved clarity and reliability by correcting pixel data units to counteract the distortion caused by slanted lenses.

AI summary
An image display system includes a display device including a plurality of pixels arranged in a first direction and a second direction crossing the first direction, and a lens array disposed on an upper surface of the display device and is configured to refract an image from the display device. The display device is configured to receive image data including an object, correct at least a portion of pixel data units of the image data, and display the image according to the corrected pixel data units. Each of the corrected pixel data units is corrected by reflecting pixel values of first pixel data units of the image data adjacent from a corresponding pixel data unit in the first direction when displayed as the image.
