Touch Panel Inhibited Area Icon Erasure for Unintended Input Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image pickup apparatuses with touch panels face issues of unintended operations due to accidental inputs on the touch screen, which are not effectively detected or prevented by current technologies, leading to potential malfunctions and incorrect settings.
Innovation Solution
An image display device and method that sets a predetermined inhibited area on the touch panel, where the control unit determines if an operation is within this area, and upon detection of an unintended input, erases displayed icons to alert the user, thereby recognizing and preventing unintended operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch panel is provided to allow various settings by tapping icons, then ease of operation is improved, but unintended operations occur when the panel is touched accidentally during normal use
Solution Approach 1:
The touch panel display area is segmented into multiple independent icon regions, each representing a different setting function. By dividing the interface into discrete selectable elements, the system can detect and respond to intentional icon selections while ignoring accidental touches that do not align with specific icon boundaries, thus maintaining ease of operation while improving reliability.
Solution Approach 2:
The control unit acts as an intermediary between the touch panel input and the setting execution. It processes touch inputs by determining whether they correspond to valid icon selections before executing any settings, thereby preventing unintended operations while preserving the ease of use provided by the touch interface.
2Adaptability or versatility
If the display panel is made tiltable to improve viewing angles, then adaptability is improved, but accidental touches during tilting operations cause unintended inputs
Solution Approach 1:
The display panel is designed to be tiltable, allowing users to adjust viewing angles for different shooting orientations. The system dynamically adapts to the panel's tilted state while maintaining accurate touch detection, enabling both adaptability for various viewing conditions and reliability by ensuring touch inputs are accurately registered regardless of panel orientation.
Solution Approach 2:
The touch detection capability is optimized for specific regions and orientations of the display panel. By adjusting detection sensitivity and validation rules based on the panel's current tilt state, the system maintains reliable operation in both portrait and landscape orientations while preventing accidental inputs that may occur during tilting movements.
3Ease of operation
If no inhibited area is set on the touch panel, then ease of operation is maximized, but unintended operations cannot be detected or prevented
Solution Approach 1:
The display area is divided into multiple icon regions, with each icon representing a specific setting function. This segmentation allows the system to distinguish between intentional icon selections and accidental touches, enabling reliable operation while maintaining ease of use through the intuitive touch interface.
Solution Approach 2:
The control unit serves as an intermediary that validates touch inputs by determining whether they correspond to valid icon selections. This mediation layer prevents unintended operations while preserving the ease of operation provided by the touch panel, without requiring inhibited areas that would block legitimate inputs.

AI summary
An image display device includes a display unit configured to display at least an image and an icon relating to a predetermined setting, a touch panel which allows input of operations, and on which a predetermined inhibited area is set, and a control unit configured to perform control so that, after the control unit sets the predetermined inhibited area, when an operation has been input by the touch panel, the control unit determines whether or not the operation has been input within the predetermined inhibited area, and, in a case where the operation has been input within the predetermined inhibited area, by erasing the icon displayed by the display unit, a user is allowed to recognize that an unintended operation has been input within the predetermined inhibited area.
