Overview
This IP core complies with the latest JPEG standard, which was established by ISO/IEC JTC 1/SC29/WG1 18181 in 2022/1 and is characterized by high compression and high quality.
A new still image coding standard established in “ISO/IEC 18181” in 2022/1.
- Compared to existing JPEG, it has higher compression and quality of still images.
- Wide color gamut, HDR compatible.
- Equipped with lossless JPEG transcoding (existing JPEG ⇔ JPEG XL) function.
- Optimized for responsive web design.

Shikino today announced that it has launched a new still image codec IP, “KJN-8EX”, and commenced sales on July 31, 2015. As a new product from the “KJN series” with the world’s top share in the still image compression/decompression technology, Shikino developed this still image codec IP which has the high-speed image processing performance, 16X speed (16 data/clock), in the JPEG compression/decompression with high bit depths (8-bit/10-bit/12-bit).
Shikino today announced that it has launched a new still image Encoder IP. As a new product from the "KJN series" with the world's top share in the still image compression/decompression technology, Shikino developed this still image encoder IP which has the world's highest image processing performance, 32X speed (32 data/clock) and the JPEG compression function with high bit depths (8-bit/10-bit/12-bit).
Shikino developed this still image decoder IP which has the world’s first image processing performance, 16X speed (16 data/clock), in the JPEG decompression with high bit depths (8-bit/10-bit/12-bit). The product is most suitable for the mobile/broadcasting/ medical/aerospace fields and so forth.
Shikino High-Tech will exhibit at Embedded World 2015 in Nurnberg Germany. We will show our JPEG IP at exhibition.
