| Outline of Final Research Achievements |
In this research, we applied various algorithms such as line-based motion prediction processing, dynamic range adaptive quantization, and context adaptive semi-fixed length coding based on the newly proposed line-based coding processing. As a result, this coding method realized ultra-low-latency performance of the order of 1/1000 microseconds compared to the conventional method. At the same time, it was verified that it has functional superiority as an encoding method such as high image quality performance and high compression rate of up to 20%. Furthermore, the superiority of the circuit amount and power consumption was verified by the architectural design and circuit implementation of this coding method. This result can be applied to application fields of real-time high-definition image sensing and ultra-low-latency transmission of in-vehicle equipment, medical equipment, and information equipment such as VR/AR.
