JPEG Encoder/Decoder High quality, high speed, low power consumption Version

Product Overview

  • Techno Mathematical has enhanced the performance of its software encoder/decoder that complies with the JPEG standard (ISO/IEC 10918-1 Baseline).
  • By incorporating the proprietary computer algorithm “DMNA” it achieves faster processing with lower power consumption than the free software libjpeg-turbo.
  • Efficient parallel processing allows the encoder to deliver consistent throughput in environments requiring real-time playback.
  • It can be used in a wide range of applications, including digital cameras, surveillance cameras, mobile devices, and cloud environments.
  • Efficient compression technology delivers clear image quality, fast processing performance, and low power consumption.

Features

  • Equipped with proprietary computer algorithm “DMNA”　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　It significantly reduces the computational load, achieving both high-speed processing and low power consumption.
  • High-speed processing and high image quality　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　Encoding is approximately 20% faster and decoding is approximately 30% faster than before, while maintaining high image quality.
  • Multi-threading supported (encoder only)　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　The encoding process has excellent parallel processing performance and delivers high throughput, making it ideal for real-time applications (decoder support is planned for the future).
  • Extensive support functions　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　The encoder allows for flexible image quality settings with quality factor, compression size, and any custom quantization table, and the decoder can decode thumbnail images within the file.
  • Flexible implementation　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　Both encoding and decoding can be embedded using a simple proprietary C API, and the encoder supports GStreamer plugins (decoder support is planned for the future).
