Image Display Control Apparatus for Efficient Multi-Image Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in efficiently selecting and verifying multiple images on a display device with limited display area, requiring repetitive scrolling and increasing time as the number of images increases, especially in devices like MFPs with insufficient display space.
Innovation Solution
An image display control apparatus and method that allows users to switch between a first screen displaying a limited number of large images and a second screen showing a greater number of smaller icons, enabling easy selection and verification of images through pinch-in and pinch-out operations, allowing more images to be displayed and selected efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If large images are displayed to enable user identification, then image identification capability is improved, but the number of images displayable at a time decreases
Solution Approach 1:
The patent segments the image selection interface into two distinct display modes: a first screen showing a limited number of large images for detailed identification, and a second screen showing many small thumbnail images for overview and selection. This segmentation allows users to switch between detailed view and comprehensive view depending on their needs, resolving the contradiction between image size and number of displayable images.
Solution Approach 2:
The patent introduces a dimensional transition between two screen states: the first screen dimension emphasizes image size and detail, while the second screen dimension emphasizes the quantity of displayed images. By allowing users to switch between these two dimensional representations, the system accommodates both requirements of large image display and multiple image display simultaneously.
2Measurement precision
If the number of images displayed at a time is limited, then image identification is improved, but the time required for checking selected images increases
Solution Approach 1:
The patent implements preliminary action by displaying thumbnail images in the second screen that represent all selectable images before the user makes selections. Users can preview all images in thumbnail form, make selections, and then switch to the first screen to verify selections without needing to scroll back through multiple screens. This preliminary overview action reduces the time required for final verification.
Solution Approach 2:
The system provides feedback by displaying thumbnail images that indicate which images have been selected. When users switch between screens or make selections, the thumbnail display updates to reflect the current selection state, allowing users to quickly verify selections without scrolling through all images. This feedback mechanism reduces verification time while maintaining identification accuracy.
3Reliability
If users scroll through images to check selections, then complete verification is achieved, but user burden increases
Solution Approach 1:
The patent makes the thumbnail display in the second screen serve multiple functions: it acts as both a navigation interface for selecting images and as a verification interface for checking selections. The same thumbnail view that allows users to scroll through and select images also provides a comprehensive overview of all selections made. This multi-functionality eliminates the need for separate verification actions, reducing user burden while maintaining verification completeness.
Data Source
AI summary
An image display control apparatus includes: a storage storing data sets; and a controller. The controller displays a first screen containing at least two of first data relating images corresponding to the data sets. When a first operation is accepted during display of the first screen, the controller replaces the first screen with a second screen containing at least three of second data relating images corresponding to the data sets. At least one second data relating image is displayed with information indicating that its corresponding data is set as data to be output. Each second data relating image has a display area smaller than that of each first data relating image. The number of second data relating images on the second screen is greater than that of first data relating images on the first screen.
