Dual Camera Auto Focus Using Front Sensor Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Controlling zooming and focus for cameras on devices like smartphones and tablets is difficult, especially when using one hand, as it is challenging to hold the device and provide input for zoom or focus simultaneously.
Innovation Solution
A system that uses a first camera to determine parameters for controlling a second camera, such as zoom and focus, by generating images of the user and using image processing to adjust the camera settings based on the user's distance and orientation, allowing for automatic control of the second camera's field of view, zoom, and focus without manual input beyond a certain distance threshold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual control of camera settings is used, then precision of camera adjustment is improved, but ease of operation deteriorates
Solution Approach 1:
The system uses the front camera to automatically detect user distance and orientation, then self-adjusts the second camera's zoom and focus parameters without requiring manual user input. This resolves the contradiction by making the camera system serve itself, achieving precise automatic adjustment while maintaining ease of operation.
Solution Approach 2:
The system continuously monitors user position through the front camera and uses this feedback to dynamically adjust the second camera's parameters. This closed-loop feedback mechanism ensures precise camera control while eliminating the need for manual operation, thus resolving the contradiction between precision and ease of operation.
2Ease of operation
If automatic camera control is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The front camera serves dual purposes: its primary function for capturing user images is enhanced with a secondary function of determining distance and orientation for automatic camera control. This multi-functionality approach reduces overall system complexity by reusing existing hardware rather than adding dedicated sensors.
Solution Approach 2:
The system uses image processing algorithms as an intermediary between the front camera and the second camera control. This software mediator translates simple image data into complex camera parameter adjustments, reducing the need for additional hardware components and simplifying the overall system architecture.
3Adaptability or versatility
If multiple cameras are used, then camera functionality is improved, but device complexity increases
Solution Approach 1:
The front camera acts as an intermediary device that provides distance and orientation information to control the second camera. This intermediary approach enables sophisticated multi-camera functionality while managing complexity by using one camera to control another, rather than requiring independent control systems for each camera.
Data Source
AI summary
In one aspect, a device includes a processor, a first camera accessible to the processor, a second camera accessible to the processor, and storage accessible to the processor. The storage bears instructions executable by the processor to receive input from the first camera and, based at least in part on the input from the first camera, determine at least one parameter for at least one action associated with the second camera.
