This document proposes a solution for high image compression to address issues with large file sizes from high resolution cameras on smartphones. It introduces a new Jpeg SBS technology that can highly compress images while maintaining good image quality and small file sizes. It also presents an Advanced PNG format that provides even higher compression rates while keeping very high image quality. Sample photos demonstrate the compression achieved by each technique. The document outlines the benefits of these compression technologies for reducing costs, data usage, and improving user experience with respect to uploading and sharing photos.

① Remarks : 1G bps – 15,000 USD per month.
② Compression rate of APNG format is very high compared to PNG format.
The effect is much more effective.
