Electronic Album Grid Cell Enlargement via Finger Gesture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic album apparatuses face difficulties in arranging images in a grid format in a visually appealing manner due to arbitrary image enlargement sizes, leading to misalignment of grid lines and challenges in precisely adjusting image sizes using finger gestures, especially when image sizes are small compared to finger thickness.
Innovation Solution
An electronic album apparatus with an album screen generating unit, operation accepting unit, enlargement target determining unit, cell enlargement area determining unit, and enlargement processing unit that allows users to easily arrange images by generating an electronic album screen with image display cells of standardized sizes, accepting touch operations, determining enlargement targets, and adjusting image sizes in accordance with finger gestures, ensuring alignment and aesthetic arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If arbitrary enlargement size is allowed for images in the electronic album screen, then the enlargement size can be customized to user preference, but the grid block lines become misaligned and the visual appearance deteriorates
Solution Approach 1:
The display screen is divided into a grid of reference boxes, and image display cells are constrained to integer multiples of these reference boxes. This segmentation approach allows customization within discrete units while maintaining alignment with the grid structure, resolving the contradiction between enlargement flexibility and grid alignment.
Solution Approach 2:
The system dynamically adjusts the enlargement size based on the number of reference boxes, allowing the image display cell size to change in discrete steps (1x, 2x, 3x, etc. of reference boxes) while maintaining alignment. This dynamic adjustment resolves the contradiction by providing adaptable sizes that preserve grid alignment.
2Quantity of substance
If small image sizes are used in the grid, then more images can be displayed on the screen, but precise adjustment of enlargement size becomes difficult when using finger gestures
Solution Approach 1:
By segmenting the enlargement control into discrete reference box units, the system provides clear visual and tactile feedback during finger gestures. Users can easily count and control the number of reference boxes to enlarge, making operation intuitive even for small images that occupy only a few reference boxes.
Solution Approach 2:
The reference boxes serve as an intermediary between the finger gesture and the image enlargement. Instead of directly controlling pixel-level enlargement, users control the number of reference boxes, which then determines the enlargement size. This intermediary makes precise control achievable even for small images.
3Ease of operation
If the enlargement size is determined by finger gesture interval, then the operation is intuitive, but the alignment with grid block lines cannot be ensured
Solution Approach 1:
The system dynamically snaps the enlargement size to the nearest integer multiple of reference boxes during finger gestures. As the user performs the gesture, the enlargement size adjusts in discrete steps aligned with the grid, maintaining both the intuitive nature of gesture control and precise grid alignment.
Solution Approach 2:
The system provides visual feedback during finger gestures to indicate when the enlargement size aligns with grid boundaries. This feedback mechanism allows users to intuitively adjust the enlargement while ensuring alignment with the grid block lines, resolving the contradiction between gesture intuitiveness and alignment precision.

AI summary
A plurality of display cells (CL) are arranged in a grid form on an album screen (14). In each display cell (CL), an image (P) in one frame is arranged, and the size of the display cell (CL) is changed to be an integer multiple of a reference size in units of the reference size. A cell enlargement instruction for enlarging the display cell (CL) is accepted through a gesture of tracking the album screen (14) with a finger. In accordance with a track (TR) of the finger (F), an enlargement area is determined. The display cell (CL) that is an enlargement target and the image (P) are enlarged in accordance with the determined enlargement area.
