Image Display Controller Pre-reading Scroll Speed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional medical image display devices experience delays in displaying image data after designation due to the need for on-demand image acquisition and the requirement for special manipulations to scroll irreversibly compressed images into uncompressed ones, leading to suboptimal image quality and user inconvenience.
Innovation Solution
An image display device that anticipates and pre-reads image data from an image archive based on scrolling speed and priority, using a controller to manage data retrieval and display, allowing for efficient and seamless scrolling without degrading image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If irreversibly compressed images are received to reduce data volume and reception time, then image display speed is improved, but image quality deteriorates
Solution Approach 1:
The system pre-loads multiple image data (including both irreversibly compressed and reversibly compressed versions) into memory before they are actually displayed. This preliminary action allows the display to quickly access high-quality image data without waiting for real-time compression/decompression operations, thus maintaining both speed and quality.
Solution Approach 2:
The system dynamically changes the compression parameter by storing both irreversibly compressed images (for speed) and reversibly compressed images (for quality) in the memory. When displaying, the system can select the appropriate compression level based on the specific display requirements, effectively changing the parameter to optimize both speed and quality.
2Quantity of substance
If on-demand image acquisition is used, then data volume is reduced, but display time is increased
Solution Approach 1:
The system performs preliminary action by pre-loading multiple image data into memory based on predicted user needs. This allows the actual display operation to occur instantly from memory without waiting for on-demand acquisition, significantly reducing display time while still maintaining efficient data management.
Solution Approach 2:
The system uses feedback from user interaction patterns to predict which images will be needed next. This feedback mechanism allows the system to proactively load relevant images into memory, optimizing the balance between data volume and display time by only pre-loading images that are likely to be needed.
3Manufacturing precision
If JPEG2000 compression is used for reversible compression, then image quality is maintained, but special manipulations are required to scroll between compressed and uncompressed images
Solution Approach 1:
The system performs self-service by automatically managing the selection and display of image data based on user interaction patterns. It predicts which images will be needed and loads them automatically into memory, eliminating the need for users to manually manipulate between different compression formats. The system handles the technical complexity autonomously while providing simple user experience.

AI summary
An image display device connected to an image archive device that stores multiple image data, the image display device comprising: a memory that stores address information of said multiple image data; a display part that is capable of scroll-displaying said image data in a predefined order; a manipulation part for inputting an instruction regarding the scroll display of the image data displayed on said display part; and an image display controller that determines image data to be read from said image archive device depending on the image data and scrolling speed of a display object designated with an instruction that has been input by said manipulation part, reads the image data from said image archive device based on said address information, and also causes said display part to display the image data of a new display object from among the image data that have been read.
