Endoscopic Image Display Mode Switching with Scroll Position Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In scrollable image display methods, users face inefficiency when switching from a mode displaying many small images to a mode with fewer larger images, as they must re-search for desired images, and existing techniques require cumbersome selection operations.
Innovation Solution
An image display device with a display control unit that switches the display mode by positioning the image that goes out of the screen first in the forward direction to remain out of the screen in the new mode, eliminating the need for re-selection by ensuring the desired image is visible initially in the new mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If images are displayed from the beginning in the switched mode, then the display mode switching is simple, but the user needs to re-search for the desired image from the beginning
Solution Approach 1:
The system performs preliminary action by automatically determining and positioning the desired image in the display area before the user actually needs to view it. When display mode switching is detected, the system proactively calculates which image should be displayed based on scroll position and displays it immediately, eliminating the need for users to re-search from the beginning.
2Measurement precision
If the user selects at least one image to be displayed in the switched mode, then the desired image can be displayed in the new mode, but the user needs to perform a troublesome selecting operation
Solution Approach 1:
The system performs self-service by automatically determining which image the user wants to view based on the current scroll position and display context. The display control unit calculates the desired image position without requiring any selection input from the user, making the system serve itself rather than requiring the user to perform troublesome selection operations.
Solution Approach 2:
The display control unit acts as an intermediary between the user's implicit intent (indicated by scroll position) and the actual display output. It translates the scroll position information into the appropriate image selection and positioning in the new display mode, eliminating the need for direct user selection while maintaining accurate image positioning.
3Productivity
If many small images are displayed, then browsing efficiency is improved, but visual recognizability of each image deteriorates
Solution Approach 1:
The system applies dynamics by allowing the display mode to change flexibly between displaying many small images and fewer large images. The display control unit dynamically adjusts the number and size of displayed images based on user interactions (scrolling and mode switching), enabling the system to adapt between browsing efficiency and visual recognizability as needed.

AI summary
A display control unit (23) scrollably displays a plurality of images to be displayed in a specific display area within a screen. An operation receiving unit (21) receives a scroll instruction and a display mode switching instruction that are issued in response to a user operation. When a display mode is switched, the display control unit (23) switches a display in the display area such that, among the plurality of images in the display area displayed in the first display mode, at least one image located as a position that goes out of the display area first upon scroll in a forward direction is arranged, upon a switch to a second display mode, at a position that also goes out of the display area first upon scroll in the forward direction in the display area.
