Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Displays experience significant brightness and color alterations when switching between 2D and 3D modes, resulting in a dimmer and duller 3D viewing experience due to reduced light delivery and color shifts caused by 3D optical shutters or filters.
Innovation Solution
The implementation of image adjustment methods, including pixel value transformations and backlight intensity adjustments, based on the current display mode, along with color mapping and compensation techniques to maintain uniform brightness and color across 2D and 3D modes, utilizing an image processor that adjusts chromaticity and brightness parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If 3D display mode is used to deliver different images to each eye, then a 3D visual effect is generated, but the brightness and color of the image are significantly altered making it appear dimmer and duller
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting image processing parameters (gamma correction, color space transformation, brightness scaling) based on the display mode (2D or 3D). When switching to 3D mode, the system modifies these parameters to compensate for the reduced light delivery and color shifts, ensuring consistent perceived brightness and color accuracy across both modes.
Solution Approach 2:
The system implements feedback mechanisms to detect and compensate for brightness and color alterations. By monitoring the impact of 3D display parameters on image quality and using this feedback to adjust processing settings in real-time, the system maintains uniform brightness and color perception despite the inherent limitations of 3D display technology.
2Adaptability or versatility
If 3D display mode is used to provide different images to each eye, then a 3D visual effect is generated, but color shifts are introduced by spectral properties of optical shutters or filters
Solution Approach 1:
The patent employs parameter changes by implementing mode-specific color space transformations and gamma correction curves. When in 3D mode, the system applies different color processing parameters to counteract the spectral distortion introduced by optical shutters or filters, thereby maintaining color accuracy and preventing unwanted color shifts.
Solution Approach 2:
The system uses an intermediary image processing stage that acts as a mediator between the raw image data and the final display output. This intermediary processing layer compensates for the color distortion introduced by 3D optical components, ensuring that the perceived color accuracy remains high despite the spectral properties of the shutters or filters.
3Stability of the object's composition
If image adjustment is performed to maintain uniform brightness and color, then viewing experience consistency is improved, but device complexity increases
Solution Approach 1:
The patent applies dynamics by implementing adaptive image processing that changes its behavior based on the current display mode. The system dynamically switches between different processing pipelines (2D vs. 3D mode-specific processing) and adjusts parameters in real-time, which manages complexity by only activating necessary processing steps when needed rather than continuously applying all possible adjustments.
Solution Approach 2:
The system performs preliminary action by pre-configuring different image processing parameters and lookup tables for 2D and 3D modes. These pre-computed settings are ready to be applied immediately when mode switching occurs, reducing the computational burden during actual mode transitions and simplifying the real-time processing requirements.

AI summary
Embodiments of the invention relate to a display operable in 2D and 3D display modes. Methods and apparatus are provided for adjusting the colors and brightness of the image data and/or intensity of the display backlight based on the current display mode and/or color-grading of the image data. For example, when switching to a 3D display mode a color mapping may be performed on left and right eye image data to increase color saturation in particular regions, and/or the backlight intensity may be increased in particular regions to compensate for lower light levels in 3D display mode.
