Rotatable Display Power Threshold Control for Self-Shooting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In self-shooting scenarios, existing technologies often inadvertently shift cameras to a power saving state during prolonged non-operation periods, leading to unintended auto power-off and potential erroneous touch operations, especially when users wear cameras around their necks or hold them in ways that make it difficult to operate the camera's back panel.
Innovation Solution
An image pickup apparatus with a rotatable display unit that selectively changes its direction between an image pickup direction and an opposite direction, featuring a power saving unit that extends the time before shifting to a power saving state when the display is in the image pickup direction, and a control unit that adjusts thresholds based on the display's orientation to prevent unintended power-offs and operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the camera automatically shifts to power saving state after predetermined non-operation time, then power consumption is reduced, but unintended auto power-off occurs during self-shooting preparation
Solution Approach 1:
The patent applies dynamics by making the inactivity detection period variable rather than fixed. The control unit dynamically adjusts the period based on detected user actions - extending it when self-shooting is detected (display unit inverted) and maintaining it short when no special conditions exist. This resolves the contradiction by allowing power saving when appropriate while preventing unintended power-off during critical moments like self-shooting preparation.
Solution Approach 2:
The system uses feedback by continuously monitoring user actions and device state (particularly display unit orientation) to adjust the inactivity detection period. When the display unit is detected in an inverted position indicating self-shooting mode, the system feedback-loops to extend the inactivity period, preventing auto power-off during preparation. This feedback mechanism ensures power saving functionality operates reliably without causing unintended shutdowns.
2Ease of operation
If the display unit is inverted for self-shooting, then the user can check angle and expression, but the time for shooting preparation is lengthened causing auto power-off
Solution Approach 1:
The patent dynamically adjusts the inactivity detection period based on display unit orientation. When inverted for self-shooting, the period is extended to accommodate the longer preparation time needed. This resolves the contradiction by allowing sufficient preparation time for self-shooting while preventing auto power-off, and returning to normal shorter periods when self-shooting is not active to maintain power efficiency.
3Loss of energy
If the power supply is turned on by touch operation on touch panel, then power saving is achieved, but unintended operations occur when user body contacts the panel
Solution Approach 1:
The patent applies preliminary anti-action by implementing a confirmation mechanism before executing power-on from touch. When the touch panel is in an inverted position (self-shooting mode), the system requires additional validation or ignores touch inputs that would normally trigger power-on. This prevents erroneous operations when the user's body accidentally contacts the panel during self-shooting preparation, while still allowing intentional touch operations when appropriate.
4Reliability
If the inactivity detection period is shortened to prevent unintended power-off, then reliability is improved, but power consumption increases
Solution Approach 1:
The patent resolves this contradiction by making the inactivity detection period dynamic rather than uniformly short. The control unit extends the period specifically when self-shooting conditions are detected (inverted display position), and maintains shorter periods during normal operation. This allows the system to prevent unintended power-off during critical self-shooting preparation while consuming minimal power during regular usage patterns.

AI summary
An image pickup apparatus includes a display unit that changes a display direction to at least one of an image pickup direction of an image pickup unit or an opposite direction, a power saving unit that executes a power saving function of reducing power consumption in response to a period in which an operation from a user has not been accepted exceeding a threshold, and a control unit that performs control such that the threshold at a time when the display direction is the image pickup direction is set to be longer than the threshold at a time when the display direction is the opposite direction.
