Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices often face issues with distortion and delay due to insufficient computing performance or limited memory space, which can hinder the presentation of high-quality images.
Innovation Solution
An image display method and device that involves an image processor receiving an image signal to drive a display panel, enlarging a target area to form a first enlarged image, modifying it into a non-rectangular image as a second enlarged image, and overlaying it on the main image for simultaneous display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the graphics processor performs image enlargement and processing, then the display quality can be maintained, but the computational load increases causing distortion and delay
Solution Approach 1:
The patent divides the image processing function into two separate processors: a graphics processor that handles only the main image, and a dedicated image processor that handles enlargement and modification operations. This segmentation allows complex image processing to occur without burdening the graphics processor, thereby reducing processing delay while maintaining display quality.
Solution Approach 2:
The patent introduces an intermediary image processor between the graphics processor and display panel. This intermediary component receives the main image signal, performs enlargement and non-rectangular modification, then outputs to the display panel. This mediator handles the computationally intensive operations separately, preventing bottlenecks in the main graphics processing pipeline.
2Productivity
If the processor has high computing performance, then image processing can be done in real-time, but the device cost and size increase
Solution Approach 1:
The patent segments the processing workload between two specialized processors rather than requiring one high-performance processor. The graphics processor handles basic rendering while the dedicated image processor handles enlargement and modification. This division allows each processor to be optimized for its specific function, achieving real-time processing without requiring an overly complex or expensive single processor.
Solution Approach 2:
The patent implements self-service by having the image processor independently handle its own enlargement and modification operations without relying on the graphics processor's computational resources. This self-sufficient approach allows real-time processing of enlarged images while keeping the graphics processor focused on its primary rendering function.
3Measurement precision
If image enlargement is performed, then detailed areas can be displayed, but the computational load increases causing distortion
Solution Approach 1:
The patent segments the image processing pipeline so that enlargement operations are performed separately from the main rendering process. The image processor receives the main image, performs enlargement with dedicated algorithms, and applies non-rectangular modifications. This separation ensures that enlargement operations do not interfere with the main image rendering, preventing distortion while maintaining high detail resolution in enlarged areas.

AI summary
An image display method, comprising the following steps: receiving an image signal from a graphics processor by an image processor, wherein the image signal is configured to drive a display panel to display a main image; enlarging a target area in the main image to form a first enlarged image according to an enlargement command; modifying the first enlarged image into a non-rectangular image to use the non-rectangular image as a second enlarged image; and driving the display panel to display the main image and the second enlarged image simultaneously by the image processor, wherein the second enlarged image is overlapped on the main image.
