Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle dashboard display systems face issues with abnormal or non-display of vehicle condition information due to system faults, leading to unsafe driving conditions, and the use of high bit-depth images increases memory requirements and costs.
Innovation Solution
An image display method using original images with lower bit depth and color rendering processing to generate higher bit-depth images for display, reducing memory occupancy and costs while ensuring fast reading and response times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high bit-depth images are used for display, then display quality is improved, but memory space requirements increase
Solution Approach 1:
The patent segments the image processing into two distinct stages: storing images in low bit-depth format (1-8 bits) to reduce memory occupancy, and performing color rendering processing at display time to convert to high bit-depth format (24 bits). This segmentation allows the system to enjoy the memory efficiency of low-bit images while maintaining the display quality of high-bit images.
Solution Approach 2:
The patent applies preliminary action by pre-storing images in compressed low bit-depth format and pre-configuring color rendering parameters. The actual color conversion to high bit-depth is performed only when needed for display, based on display environment conditions. This preliminary preparation reduces memory requirements while ensuring quality display when needed.
2Quantity of substance
If low bit-depth images are used for storage, then memory space is reduced, but display quality deteriorates
Solution Approach 1:
The patent introduces color rendering parameters as an intermediary element between the stored low bit-depth image and the final high bit-depth display output. These parameters contain color space transformation data that enable the system to convert from the compressed storage format to the high-quality display format, acting as a bridge that preserves quality despite compression.
Solution Approach 2:
The patent dynamically changes the bit-depth parameter based on the processing stage: images are stored in low bit-depth (1-8 bits) to save memory, then converted to high bit-depth (24 bits) during color rendering processing before display. This parameter transformation allows the system to optimize both memory usage and display quality at different stages.
3Adaptability or versatility
If color rendering processing is performed, then display adaptability is improved, but processing complexity increases
Solution Approach 1:
The patent implements self-service by having the display device automatically detect its own display environment characteristics and select appropriate color rendering parameters without external intervention. The system autonomously adjusts color space conversion based on its own display capabilities, simplifying the overall process despite the complexity of color rendering.
Solution Approach 2:
The patent creates a universal color rendering processing framework that can adapt to different display devices and environments using a single set of low bit-depth stored images. The color rendering parameters serve multiple functions: color space conversion, gamma correction, and adaptation to different display characteristics, making the system universally applicable across various display scenarios.

AI summary
An image display method includes: obtaining both an original image and a color rendering parameter corresponding to an image to be displayed, a bit number of color depth of the original image being smaller than a bit number of color depth of the image to be displayed; generating the image to be displayed according to the original image and the color rendering parameter; and displaying the image to be displayed.
