Clipped Pixel Hue Correction in Image Display Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical imaging systems struggle to display colors naturally due to limitations in adjusting contrast, leading to unnatural and desaturated appearances of colors.
Innovation Solution
A control module in the image display system amplifies signals and adjusts the hue of clipped pixels to match the intended color, using a formatter to correct the hue and saturation levels, thereby enhancing color accuracy and naturalness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If optical imaging systems implement adjustable contrast, then contrast is improved, but color accuracy deteriorates (colors become unnatural and desaturated)
Solution Approach 1:
The system performs preliminary identification of clipped pixels before final image output. By detecting pixels that have been clipped during contrast enhancement and correcting their hues in advance, the system prevents color accuracy deterioration while maintaining improved contrast. The formatter identifies clipped pixels and adjusts their hues to match intended colors before the image is displayed.
Solution Approach 2:
The system implements a feedback mechanism where the formatter continuously monitors pixel values to identify clipped pixels, then feeds back correction signals to adjust the hues of these pixels. This closed-loop approach ensures that contrast enhancement does not permanently degrade color accuracy, as the system automatically detects and corrects clipped pixel issues.
2Illumination intensity
If signal amplification is applied to enhance image brightness, then brightness is improved, but color fidelity deteriorates (clipped pixels generate incorrect hues)
Solution Approach 1:
The formatter performs preliminary correction of clipped pixel hues before the amplified signal is displayed. By identifying pixels whose hues have been distorted during amplification and adjusting them to match intended colors, the system restores color fidelity while maintaining the brightness benefits of signal amplification.
Solution Approach 2:
The system applies selective correction only to clipped pixels rather than uniformly processing the entire image. The formatter identifies specific pixels with incorrect hues caused by amplification and adjusts only those pixels, preserving the amplified brightness benefits while correcting localized color fidelity issues.

AI summary
A control module for use in an image display system includes a gain module operable to amplify a signal received by the control module and to communicate an amplified signal having at least one clipped pixel. The at least one clipped pixel is capable of generating a color having a hue that is substantially different than a hue of a color that was specified by the signal. The control module further includes a formatter coupled to the gain module. The formatter operable to receive the amplified signal and to adjust the hue of the color associated with the at least one clipped pixel. In one particular embodiment, the hue of the color associated with the at least one clipped pixel is adjusted to substantially the hue of the color that was specified by the signal.
