Camera Accessory Display Controller Power Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Interchangeable lenses with display elements waste electric power due to automatic switching on and off with camera power states, especially when attached to cameras with multiple image capturing modes or different types, as they do not account for the specific image capturing mode or camera type.
Innovation Solution
An accessory with a display element and a display controller that controls the display based on the set image capturing mode or camera type, turning off the display after a predetermined time when the camera switches from an image capturing mode to a non-image capturing mode, and utilizing a non-transitory computer-readable storage medium for display control programs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display element starts display in response to turning on of camera power and ends display in response to turning off of camera power, then the display is always available when camera is powered, but electric power is wasted due to unnecessary display activation in non-image capturing modes
Solution Approach 1:
The display controller dynamically adjusts display activation based on camera operating mode. In still image capturing modes, the display remains active when camera is powered on. In moving image capturing modes, the display remains inactive. This dynamic adaptation resolves the contradiction by making display availability context-dependent rather than static.
Solution Approach 2:
The system changes the display control parameter (active/inactive state) based on the camera capturing mode parameter. When capturing mode changes from still image to moving image mode, the display parameter switches from active to inactive, optimizing power consumption while maintaining necessary display availability.
2Loss of information
If the display element is always active when camera is powered on, then information is always visible, but power consumption increases unnecessarily in modes where display is not needed
Solution Approach 1:
The display controller implements dynamic control where display activation is adjusted in real-time based on capturing mode. The display transitions from active state in still image modes to inactive state in moving image modes, ensuring information visibility only when necessary and eliminating energy waste in modes where display is redundant.
Solution Approach 2:
The display controller automatically detects camera capturing mode and self-adjusts display activation without user intervention. This self-service mechanism ensures information is visible when needed while automatically conserving energy when display is unnecessary, resolving the contradiction between information availability and energy conservation.

AI summary
The accessory is detachably attachable to a camera in which multiple image capturing modes are settable. The accessory includes a display element configured to electrically display information, and a display controller configured to perform a display control for controlling turning on and off of display of the information on the display element. The display controller is configured to perform the display control depending on the image capturing mode set in the camera or on a type of the camera to which the accessory is attached.
