Abstract
This paper presents an optimisation method to enhance the operating speed and reduce memory usage for implementing deep learning-based ultra-high-resolution camera solutions on mobile devices. We detail the final implementation results and propose practical methodologies for deploying high-resolution and computationally complex image solutions on mobile platforms. Specifically, we demonstrate an optimised implementation of a deep learning-based camera solution pipeline by leveraging heterogeneous computing, processor-specific optimisations and memory reuse techniques. The proposed approach is applied to a 200 MP camera solution and commercialised for the Samsung Galaxy S23 Ultra. Experimental evaluations on the S23 Ultra device reveal that while the initial implementation required 2.79 GB of memory exceeding the operational capacity of mobile devices, our optimisation techniques reduced memory usage to 490 MB and achieved a processing time of 3.95 s that enables efficient on-device operation.
