Dynamic Pressure Threshold Control for Camera Mis-Operations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image capturing apparatuses require significant finger repositioning, leading to potential mis-operations during shooting, menu setting, and reproduction, as photographers cannot see operation members while changing settings, increasing the risk of missed shots due to unintentional transitions to the shooting state.
Innovation Solution
An image capturing control apparatus with a detector to sense pressing force on a specific operation member, allowing transitions between modes based on distinct pressure thresholds, enabling quick and precise operations without repositioning fingers, thereby reducing mis-operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch panel is used for operations during menu setting and reproduction, then finger repositioning is reduced, but mis-operations occur due to unintentional transition to shooting state
Solution Approach 1:
The patent changes the pressure threshold parameter dynamically based on the operation mode. During menu setting and reproduction, a higher pressure threshold is required to activate the operation member, preventing accidental triggers. During shooting mode, a lower pressure threshold allows quick activation. This parameter change resolves the contradiction by allowing easy operation during shooting while preventing mis-operations during other modes.
2Ease of operation
If a single pressure threshold is used for all operations, then operation is simplified, but both quick operation during shooting and prevention of mis-operations cannot be achieved simultaneously
Solution Approach 1:
The patent makes the pressure threshold dynamic rather than static. The control unit automatically adjusts the pressure threshold based on the current operation mode detected by the control unit. This dynamic adaptation allows the system to maintain simplicity of operation while being versatile across different modes, resolving the contradiction between operational simplicity and mode adaptability.
3Productivity
If the operation member is positioned for easy access during shooting, then shooting speed is improved, but the same position causes mis-operations during menu setting and reproduction
Solution Approach 1:
The patent maintains the operation member in a fixed position for easy access during shooting, improving shooting speed. To prevent mis-operations during menu setting and reproduction, the patent changes the pressure threshold parameter to be higher during these modes. This allows the same physically accessible position to serve different functions based on the operational context, resolving the contradiction between shooting speed and reliability.

AI summary
An apparatus comprises: a detector configured to detect a pressing force applied to a specific operation member; and at least one processor which function as a control unit configured to: responsive to detection of pressing with a first pressure or more on the member during a first operation mode, perform control so that a transition to a second operation mode is made; responsive to detection of pressing with a second pressure or more during the second operation mode, perform control so that a shooting preparation process is performed, the second pressure being smaller than the first pressure; and responsive to detection of pressing with a third pressure or more during the second operation mode, perform control so that shooting is performed, the third pressure being greater than the second pressure.
