E-Ink Monochrome Image Mapping for Sharp Object Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display methods for E-ink screens result in lower definition or deformation of displayed objects due to inconsistent sizes between the image and the screen, leading to a need for scaling that loses details.
Innovation Solution
Generate a monochrome image with a size matching the display region of the E-ink screen, ensuring the target object is positioned correctly, using standard color values for pixel points to maintain definition and avoid deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the image is scaled to match the ink screen size, then the image can be displayed on the screen, but the definition and detail of the target object are lost
Solution Approach 1:
The patent applies preliminary action by pre-processing the image to identify the target object and its key features before scaling. The system determines the target display position and size of the target object in advance, then performs intelligent scaling that preserves these critical elements while adapting the overall image to the ink screen dimensions. This prevents loss of target object definition during the scaling process.
2Area of stationary object
If the image is scaled to match the ink screen size, then the image can be displayed on the screen, but deformation of the target object occurs
Solution Approach 1:
The patent applies local quality by treating different regions of the image differently during scaling. The target object region is identified and given special protection to maintain its original shape and proportions, while other background regions are scaled uniformly to fit the ink screen. This selective approach ensures the target object does not deform even when the overall image is resized.
3Adaptability or versatility
If a monochrome image is generated with standard color values, then the image is compatible with the ink screen, but color information is lost
Solution Approach 1:
The patent applies the taking out principle by extracting only the essential color information needed for ink screen display. Instead of converting the entire image to simple monochrome, the system identifies and preserves key color characteristics of the target object, representing them using standard color values that are compatible with ink screen technology. This selective extraction maintains color information where important while ensuring compatibility.

AI summary
An image display method and apparatus are provided. The method includes: determining a target display position of a target object in an original image and a first size of a display region of an ink screen (102); generating a monochrome image with the first size according to the original image, where color values of pixel points in the monochrome image include at least one standard color value, and the target object is located at a target display position in the monochrome image (104); sending the monochrome image to the ink screen, so that the monochrome image is displayed by the ink screen in the display region (106). This method can improve the definition of the monochrome image displayed by the ink screen.
