AI Technical Summary
Dual Pixel autofocus technologies in smartphones face challenges such as high processing power consumption, limited ability to capture edge objects, and inability to utilize semantic relationships between regions of interest, leading to performance issues and battery drain.
A method that intelligently activates and deactivates dual pixels based on importance hierarchy and user preferences, using multiple cameras to focus on strategic regions of interest (ROIs) through a two-level auto-focus mechanism, optimizing pixel usage and leveraging multiple image sensors.
This approach reduces processing power consumption, enables faster focusing, enhances user personalization, improves edge focus, and increases overall image clarity by selectively focusing on sub-ROIs, thus addressing the limitations of conventional dual pixel autofocus.
