Portable Device Sensor-Based Partial Image Scrolling Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for intuitive scrolling operations on portable devices, such as cellular phones, require a guide sheet and are not user-convenient.
Innovation Solution
A non-volatile storage medium with a control program that includes sensors for detecting movement and attitude, allowing the device to specify and display partial image areas based on detected information, enabling intuitive scrolling and zooming operations without a guide sheet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a guide sheet with coordinate indicator markers is used for scrolling operations, then intuitive scrolling control is achieved, but user convenience deteriorates due to the requirement of preparing and using an external guide sheet
Solution Approach 1:
The patent extracts the coordinate indicator markers from the external guide sheet and integrates them directly into the displayed image content. The image processing unit generates virtual coordinate markers that are overlaid on the displayed image, allowing the display unit to provide scrolling reference information without requiring a separate physical guide sheet. This eliminates the external dependency while maintaining intuitive scrolling control.
Solution Approach 2:
The patent creates a virtual copy of the coordinate indicator markers within the digital display system. Instead of using physical markers on a separate guide sheet, the system generates digital coordinate indicators that are rendered as part of the displayed image. These virtual markers serve the same function as physical markers but eliminate the need for external materials.
2Loss of information
If the entire image is displayed on a narrow display panel, then complete image information is provided, but ease of operation deteriorates due to difficulty in viewing and navigating large images
Solution Approach 1:
The patent segments the displayed content into multiple regions by overlaying coordinate indicator markers that divide the image space into quadrants or sections. These visual segments help users orient themselves within the larger image and understand their current position, making navigation more intuitive when viewing complete images on narrow displays.
Solution Approach 2:
The patent adds a visual reference dimension by overlaying coordinate markers and position indicators on the displayed image. This creates an additional layer of information that provides spatial context without requiring the user to mentally map the image coordinates, effectively adding a navigational dimension to the display.

AI summary
A non-volatile storage medium storing a control program readable by a computer of a portable device including a sensor to output detected information indicative of at least one of a movement and an attitude of the portable device, a data memory portion to store image data, and a display portion to display an image on the basis of the image data, wherein the control program enables the computer to function as: a partial area specifying portion to specify, as a partial image area, an area of a partial image that is a portion of the image represented by the image data, on the basis of at least one of the movement and attitude of the portable device indicated by the detected information; and a display control portion to display the partial image in the partial image area specified by the partial area specifying portion, on the display portion.
