JPEG 2000 compression specialist intoPIX have introduced a new range of JPEG 2000-RAW IP-cores for FPGA at IBC2013. The cores manage HD, 4K or 8K Bayer image sensor output from 10 to 16-bit with a RAW visually lossless compression at a variety of frame rates.
intoPIX believes there are many good reasons to shoot in compressed JPEG 2000 RAW. A higher image quality can be managed within the constraints of the medium compared to other formats at the same file size. Also the wavelet scalability of JPEG 2000 allows encoding image features at different formats separately. In addition, the royalty-free JPEG 2000 standard is already widely adopted by the cinema and broadcast industries and recognised for its high quality in production and post-production workflows.
The new intoPIX JPEG 2000-RAW IP-cores generate fully standard JPEG 2000 files (ISO 15444-1) from a camera’s digital sensor in an attempt to maximise cinema and TV 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 optimised and flexible rate allocation. Similar to the advantages obtained with RAW files, it preserves access to the control over white balance, exposure and color grading in post-production.
“Cameras continue to feature larger image sensors, higher resolutions, and a variety of schemes for improving color fidelity and image noise reduction. The continued use of uncompressed or RAW files means that the ultimate image quality can't be maintained without creating monster-size files”, said Jean-Baptiste Lorent, Product & Marketing manager at intoPIX.
