Automatic Image Area Maximization on Display Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 2-point touch technology for zooming and viewing images on electronic devices requires manual adjustment to fit desired areas within the screen, which can be inefficient, especially when parts of the image need to be zoomed in or out and repositioned.
Innovation Solution
A method and system that allow users to select a target area of an image on a display screen, automatically translating and resizing it to maximize its display within the screen, even if the selected area is initially outside the visible portion, using processor-controlled image management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional 2-point touch technology is used for zooming and viewing images, then the device maintains simple operation, but the user must manually adjust and reposition the image multiple times to fit the desired area within the screen
Solution Approach 1:
The system performs preliminary actions by automatically calculating and executing the translation and scaling transformations needed to fit the selected image area onto the display screen. Instead of requiring users to manually zoom and reposition the image through multiple touch gestures, the system pre-computes the optimal view parameters based on the selected area coordinates and screen dimensions, then automatically applies these transformations in a single operation.
2Productivity
If manual zooming and repositioning is required to display a specific image area, then the device maintains simple processing, but the user experience is degraded due to multiple adjustment steps
Solution Approach 1:
The system implements self-service by automatically determining the optimal display parameters for the selected image area without requiring user intervention for zooming and repositioning. The processor autonomously calculates the scaling factor and translation offset based on the relationship between the selected area coordinates and the display screen dimensions, then automatically applies these transformations to present the fitted image view.
3Loss of time
If the system automatically translates and scales the image to fit the selected area, then the display efficiency is improved, but the processing complexity increases
Solution Approach 1:
The system replaces manual mechanical interaction (multiple touch gestures for zooming and panning) with automated computational processing. The processor calculates the transformation parameters using mathematical relationships between the selected area coordinates and screen dimensions, then applies these transformations through software control, substituting the need for iterative manual mechanical adjustments with a single automated computational operation.

AI summary
Methods, computer program products, and systems, for example, for controlling display of an image on a display screen includes, for example, receiving, by one or more processor, data regarding a user selected area relative to a first portion of an image displayed on a display screen to define a second portion of the image, at least a portion of the second portion of the image being outside the first portion of the image displayed on the display screen, and automatically controlling, by the one or more processor, display of the second portion of the image on the display screen based on the user selected area of the image to generally maximize display of the second portion of the image within the display screen.
