Digital Zoom Automatic Resolution Mode Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Camera modules in wireless communication terminals often restrict digital zoom functionality in high-resolution modes, leading to video distortion and user inconvenience, as users cannot execute digital zoom without switching to lower resolution modes.
Innovation Solution
An apparatus and method that automatically convert the camera to a maximum resolution mode supporting digital zoom when the digital zoom key is pressed, allowing digital zoom execution in high-resolution modes by controlling the video processing unit to adjust the resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If digital zoom function is blocked in high-resolution mode to prevent video distortion, then video quality is preserved, but user convenience deteriorates as users cannot execute digital zoom
Solution Approach 1:
The system dynamically adjusts the resolution mode based on the user's zoom operation. When digital zoom is activated in high-resolution mode, the system automatically converts to a lower resolution mode that supports digital zoom, then performs the zoom operation. This dynamic switching resolves the contradiction by adapting the resolution mode to the user's needs rather than statically blocking the function.
Solution Approach 2:
The system changes the resolution parameter automatically when digital zoom is requested. The control unit detects the zoom key input and converts the resolution from high-resolution mode to a lower resolution mode that supports digital zoom processing. This parameter change enables the digital zoom function while managing video quality through controlled resolution adjustment.
2Adaptability or versatility
If users manually switch to lower resolution mode to enable digital zoom, then digital zoom function becomes available, but operation complexity increases and time is lost
Solution Approach 1:
The system performs the resolution mode conversion automatically without requiring user intervention. When the user presses the digital zoom key, the control unit automatically converts from high-resolution mode to a lower resolution mode that supports digital zoom, executes the zoom function, and then restores the original resolution mode. This self-service automation eliminates the need for users to manually switch modes, reducing operation complexity to a single zoom key press.
Solution Approach 2:
The system prepares the resolution mode in advance to support the digital zoom operation. Before executing the digital zoom function, the system automatically converts to a suitable lower resolution mode that can handle digital zoom processing. This preliminary action ensures the digital zoom function is available when needed without requiring complex user setup procedures.
3Measurement precision
If high-resolution mode is maintained for photographing, then photo definition is improved, but digital zoom function becomes unavailable
Solution Approach 1:
The system maintains high-resolution mode as the default for photographing to preserve photo definition. When digital zoom is activated, the system dynamically switches to a lower resolution mode that supports digital zoom processing, executes the zoom operation, and then restores the high-resolution mode. This dynamic approach allows the system to maintain high photo definition while temporarily adapting to support digital zoom when needed.

AI summary
An apparatus and method of automatic conversion to a digital zoom mode allow a digital zoom to be executed by automatically converting from a high-resolution mode that does not support a digital zoom to a highest resolution mode supporting the digital zoom when a digital zoom key is pushed. The apparatus includes a key pad having a digital zoom key, a video processing unit for processing video data from the camera unit to determine a resolution and execute a digital zoom function, and a control unit for controlling the video processing unit to convert a resolution mode that does not support the digital zoom function to a highest resolution mode among resolution modes supporting the digital zoom function and execute the digital zoom function when the digital zoom key is pressed in the resolution mode that does not support the digital zoom function.
