Image Data Generation Using Inactive Pixels for Brightness Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display technologies lack effective methods to control image properties such as brightness and resolution beyond conventional limits without compromising visual quality or introducing issues like flickering or washed-out colors.
Innovation Solution
Incorporating inactive pixels into image data to adjust brightness and resolution, with mitigation techniques to maintain visual quality, such as interpolating pixel colors and varying inactive pixel patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional brightness control methods are used, then image brightness can be adjusted, but visual quality deteriorates due to washed-out colors or flickering
Solution Approach 1:
The patent segments the display into active pixels and inactive pixels, selectively controlling which pixels render image data. By segmenting the pixel population rather than uniformly dimming all pixels, the system achieves brightness control while preserving visual quality in the active regions.
Solution Approach 2:
The patent extracts and removes inactive pixels from the display output, creating a subset of active pixels that render the image. This extraction approach allows brightness control by reducing the number of rendered pixels rather than reducing the intensity of all pixels, thereby avoiding washed-out colors and flickering.
2Manufacturing precision
If conventional resolution control methods are used, then display resolution can be adjusted, but image quality and visual fidelity deteriorate
Solution Approach 1:
The patent segments the pixel array into active and inactive portions, selectively rendering only the active pixels at the desired resolution. This segmentation enables resolution control without degrading image quality, as the active pixels maintain their full resolution capabilities while simply being fewer in number.
Solution Approach 2:
The patent applies partial action by rendering only a subset of pixels (active pixels) rather than the full pixel array. This partial rendering achieves the desired resolution control while maintaining image quality in the rendered regions, avoiding the quality degradation that would result from rendering all pixels at reduced resolution.
3Reliability
If all pixels are rendered at full intensity, then visual quality is maintained, but power consumption and processing burden increase
Solution Approach 1:
The patent extracts inactive pixels from the rendering process, leaving only active pixels to be rendered at full intensity. This extraction reduces the total number of pixels requiring processing and power, while the active pixels maintain their full intensity and visual quality, thus reducing power consumption without sacrificing visual quality.
Solution Approach 2:
The patent applies partial action by rendering only the necessary active pixels rather than all pixels. This partial rendering reduces processing burden and power consumption while maintaining visual quality in the rendered regions, as the active pixels are rendered at full intensity without the need to process inactive pixels.
4Illumination intensity
If conventional dimming techniques are used, then brightness control is achieved, but flickering and washed-out colors are introduced
Solution Approach 1:
The patent segments pixels into active and inactive categories, controlling brightness by selecting which pixels are active rather than dimming all pixels. This segmentation approach achieves brightness control without introducing flickering or washed-out colors, as the active pixels maintain full intensity while simply being fewer in number.
Solution Approach 2:
The patent extracts inactive pixels from the display output, creating a subset of active pixels that render the image at full intensity. This extraction eliminates flickering and washed-out colors by avoiding the uniform dimming of all pixels, while still achieving brightness control through the reduced number of active pixels.
Data Source
AI summary
A system and method for generating image data at a data processing system, the method comprising: determining, at a first data processor unit, that an image comprising one or more inactive pixels is required to be displayed to meet one or more desired properties of the displayed image; providing first control data to cause the first or a further processor unit to generate image data which when displayed comprises the one or more inactive pixels.
