Imaging Module Transition for Seamless Digital Zoom
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The deviation of color or brightness is visible to users when imaging modules with different spectral sensitivities, such as wide-angle and telephoto modules, are replaced during digital zoom in smartphones, leading to an unsatisfactory image transition.
Innovation Solution
An imaging apparatus with a processor that captures images using both modules and adjusts the output image information, such as white balance gain and brightness, to ensure a seamless transition by correcting the image information to maintain a certain level of similarity between the two modules, thereby minimizing visible deviations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If imaging modules with different spectral sensitivities are replaced during digital zoom, then zoom functionality is achieved, but visible deviation in color or brightness occurs
Solution Approach 1:
The patent applies parameter changes by adjusting white balance gains and brightness parameters of the telephoto imaging module to match those of the wide-angle imaging module. The processor modifies these parameters dynamically during module replacement to ensure continuous color and brightness consistency, thereby resolving the visible deviation issue while maintaining zoom functionality.
Solution Approach 2:
The processor acts as an intermediary that mediates between the wide-angle and telephoto imaging modules. It captures images from both modules, compares their output image information, and applies corrective adjustments to the telephoto module's output to match the wide-angle module's characteristics, ensuring seamless transition during zoom operations.
2Adaptability or versatility
If multiple imaging modules are used to achieve different focal lengths, then imaging versatility is improved, but device complexity increases
Solution Approach 1:
The processor performs multiple functions including capturing images from both imaging modules, comparing output image information, adjusting white balance gains, modifying brightness parameters, and determining when to replace modules. This multi-functionality reduces the need for additional dedicated components, thereby managing device complexity while maintaining imaging versatility.
3Measurement precision
If imaging modules are replaced frequently during digital zoom, then zoom resolution is maintained, but power consumption increases
Solution Approach 1:
The system dynamically determines when to replace imaging modules based on zoom level requirements. The processor monitors the current zoom state and only activates the telephoto imaging module when high-resolution zoom is needed, while keeping the wide-angle module active for lower zoom levels. This dynamic operation optimizes power consumption by minimizing the activation frequency of the power-intensive telephoto module while maintaining appropriate zoom resolution.
