Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image capturing devices face challenges in seamlessly switching between wide-angle and telephoto sensors, leading to unnatural user experiences and increased power consumption due to prolonged switching times or concurrent operation of both sensors.

An electronic device configuration that controls the operation of wide-angle and telephoto sensors based on zoom magnification thresholds, allowing concurrent operation within specific magnification ranges and selective signal output to minimize switching time and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If both wide-angle and telephoto sensors operate concurrently to enable fast switching, then switching speed is improved, but power consumption increases
Solution Approach 1:
The system performs preliminary actions by having the telephoto sensor prepare and output signals in advance during the transition period before switching is needed. This allows the sensor to be ready for immediate switching without requiring continuous concurrent operation of both sensors, thereby reducing power consumption while maintaining fast switching capability.
Solution Approach 2:
The system dynamically adjusts sensor operation states based on real-time zoom magnification conditions. Instead of maintaining static concurrent operation, the control logic dynamically transitions sensors between active and standby states, optimizing the balance between switching speed and power consumption according to actual operational needs.
2Use of energy by moving object
If switching between sensors is delayed to reduce power consumption, then power consumption is reduced, but switching time increases causing unnatural user experience
Solution Approach 1:
The system executes preliminary actions by initiating signal output from the telephoto sensor before the actual switching point is reached. This head-start approach ensures that when switching is triggered, the telephoto sensor is already prepared and can transition immediately, eliminating noticeable switching delays while avoiding the need for prolonged concurrent operation that would increase power consumption.
3Stability of the object's composition
If wide-angle sensor continues outputting signals after reference condition becomes unsatisfied to ensure smooth transition, then transition smoothness is improved, but power consumption increases
Solution Approach 1:
The system uses preliminary action by having the telephoto sensor start outputting signals in advance during the transition period. This ensures that when the wide-angle sensor stops outputting, the telephoto sensor is already ready, providing smooth transition without requiring the wide-angle sensor to continue operation unnecessarily, thus reducing power consumption while maintaining transition smoothness.

AI summary
An electronic device includes an input interface, a wide-angle sensor, a telephoto sensor, and an output interface. The input interface receives a zoom magnification. The wide-angle sensor operates when the zoom magnification is smaller than a first reference magnification. The telephoto sensor operates when the zoom magnification is greater than a second reference magnification, which is smaller than the first reference magnification. The telephoto sensor operates concurrently with the wide-angle sensor when the zoom magnification is between the second reference magnification and the first reference magnification. The output interface outputs a first image based on a first signal from the wide-angle sensor when the zoom magnification is smaller than a switching magnification, which is between the second reference magnification and the first reference magnification. The output interface outputs a second image based on a second signal from the telephoto sensor when the zoom magnification is greater than the switching magnification.
