JPEG 2000-RAW (Bayer-pattern) Encoders & Decoders IP-cores

Best bayer pattern-images compression for Cameras

The JPEG 2000-RAW Encoder & Decoder IP-cores preserve perfectly the RAW output (Bayer pattern images) of Bayer-filter cameras with best-in-class JPEG 2000 compression. Offering a visually lossless quality, J2K-RAW allows also an automatic access to low-resolution preview thanks to the JPEG 2000 scalability.  

With such a rapid evolution of available image resolution, the need for highly efficient image compression is bigger than ever before for RAW data. intoPIX offers now a range of IP-cores that can adress any resolutions of image sensors from HD up to 4K or even 8K.

The intoPIX JPEG 2000-RAW IP-cores go one step further in terms of image quality possibilities maximizing Cinema and TV production and post-production capabilities. It achieves this by storing each of the sensor’s color channels separately, prior to conversion into a full color image with an optimized and flexible rate allocation. Similar to the RAW files advantages, it preserves the access to any demosaicing algorithms, the control over white balance, exposure and color grading in post-production. 

Key Features

  • Compact J2K-RAW FPGA IP-cores
    (lower power consumption)
  • Wavelet-based compression
  • JPEG 2000 ISO/IEC 15444-1
  • HD, 4K , 8K bayer pattern images
  • High frame rates support for real-time or high speed.
  • Higher image quality possibilities within a reasonable storage and bandwidth. 
  • Fast low-resolution preview access thanks to the JPEG 2000 scalability.

JPEG 2000 Benefits for RAW images (Bayer pattern images)

JPEG 2000 offers many useful features to preserve and manage high quality pictures. It revolutionize the way high-resolution image data are disseminated and analyzed. More than being a license free and an open standard supporting any resolutions , frame rates or number of components, JPEG 2000 is also a wavelet-based intra-frame codec offering visually lossless compression. 

Since there is no difference with the uncompressed RAW image quality, there are only good reasons to shoot in compressed JPEG 2000 RAW. First: you can manage higher image quality within the constraints of the recording medium compared to other formats at the same file size. Second:  the wavelet scalability of JPEG 2000 enables to encode image features at different formats separately. As a result, low-resolution preview can be decoded, without processing the entire high-resolution file. It makes it easier to directly view and edit large video files on desktop computers. Last but not least: the royalty-free JPEG 2000 standard is already widely adopted by the Cinema and Broadcast industries and recognized for its high quality in production, post-production workflows, and raw bayer compression.
