Multi-Directional Scrolling Screenshots for Complex Page Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices can only capture a screenshot in one direction when a display interface can scroll in multiple directions, limiting the ability to capture comprehensive images of complex layouts like maps or tables.
Innovation Solution
The method allows the electronic device to sequentially move a specified page in a scrolling window in multiple directions based on a preset trajectory, capturing partitioned screenshots that are then spliced to form a comprehensive target screenshot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the electronic device scrolls in only one direction to capture screenshots, then the operation is simple and the device complexity is low, but the completeness of the captured content is insufficient for multi-directional interfaces
Solution Approach 1:
The patent divides the screenshot capture process into multiple segments by implementing multi-directional scrolling capabilities. The device captures content in different directions (horizontal, vertical, and diagonal) separately, then synthesizes these segmented captures into a complete screenshot, thereby resolving the contradiction between capture completeness and operational simplicity
Solution Approach 2:
The patent extends the traditional single-direction (one-dimensional) scrolling to multi-directional (two-dimensional or three-dimensional) scrolling. By adding directional dimensions to the scrolling operation, the device can capture comprehensive content from interfaces that require multi-directional navigation, transforming a limited linear capture process into a spatial multi-axis capture system
2Loss of information
If the electronic device captures screenshots in multiple directions, then the completeness of the captured content improves, but the time required for capture and synthesis increases
Solution Approach 1:
The patent implements preliminary actions by pre-planning the scrolling trajectory and capture sequence before actually capturing the screenshot. The device determines the optimal scrolling path (horizontal, vertical, or diagonal) in advance based on the interface characteristics, which optimizes the capture process and reduces the total time required compared to ad-hoc multi-directional scrolling
Solution Approach 2:
The patent maintains continuity of useful action by implementing seamless transitions between different scrolling directions. The synthesis process continuously integrates captured content from multiple directions without interruption, ensuring that the capture operation flows smoothly from one direction to another, thereby minimizing idle time and maintaining high productivity throughout the multi-directional capture process

AI summary
A scrolling screenshot method and an apparatus, the method including displaying, by an electronic device, a first interface that displays a first part of a first page, receiving, by the electronic device, a first input, capturing the first part of the first page in response to the first input, scrolling, by the electronic device in a first direction for display, and capturing a second part of the first page, where the first part is adjacent to the second part, scrolling, after the electronic device captures the second part, by the electronic device, in a second direction, for display, and capturing a third part of the first page, where the second direction is different from the first direction, determining that a first condition is met. and synthesizing a target screenshot image in response, where the target screenshot image comprises the first part, the second part, and the third part.
