Shikino Initiative to Commence Licensing of New High-speed JPEG
Codec IP to Obtain Ultra-high Definition Images
Featured Japan’s First High Bit Depths (12-bit/10-bit) and Lossless Processing Function
Shikino High-Tech Co., Ltd. (“Shikino”) today announced that it has launched a new
high-speed JPEG codec IP , “KJN-7EX_LSC”, and commences sales today.

As a new productfrom the “KJN series” with the world’s top share in the still image compression/decompression
technology, “KJN-7EX_LSC” equips with high bit depths (12-bit/10-bit) to obtain ultra-highdefinition images and the lossless processing function to provide outstanding images without
the image quality deterioration due to the image compression/decompression.

The product ismost suitable for the medical/broadcasting/aerospace fields and so forth.
●Obtain ultra-high definition images by high bit depths
In addition to the existing 8-bit depth in JPEG, the first high bit depths (12-bit/10-bit)
mounted in Japan attains high image quality. This product is most suitable for the
medical/broadcasting/aerospace/industrial camera fields requiring color reproducibility andhigh gradation.
● Achieve outstanding images without the image quality deterioration by the image
compression/decompression technology
The lossless processing function makes it possible to achieve outstanding images without
the image quality deterioration when compressing them.

This KJN-7EX_LSC technology

is optimally applied to highly advanced medical equipments, image processing inspection
devices and aviation/aerospace equipments that have required customers to use theuncompressed and large-volume RAW images to prevent the image quality deterioration.
●Attain 60 consecutive 4K2K still images per second using the lossless processing function
The lossless processing function provides users with the 8X (8 Data/clock) processing speed(data rate).

This is optimal for consumer devices requiring high-speed consecutive

shooting (e.g., DSC, DSC-SLR, Smartphones, 8K4K displays and so forth).
The product is anticipated to meet the market demands for medical equipments, image
inspection devices, high-definition image devices, consumer devices and so on.

Also, Shikino

has developed and released “KJN-7EX” for the 12-bit/10-bit/8-bit JPEG processing that gives
customers options to choose their most suitable lineups to satisfy their requests.

*Gradation: A unit expressing color and brightness
Number of colors: Cubed gradation numbers in the RGB color model
8 bit: 256 gradations per color/16.77 million colors (8 bit applied to PC)
10 bit: 1024 gradations per color/1.07 billion colors
12 bit: 4096 gradations per color/68.71 billion colors【About JPEG Extended DCT-based process /JPEG Lossless process】
The 12-bit JPEG (Extended DCT-based process) employed in “KJN-7EX_LSC” is aninternational standard to extend general 8-bit JPEG to 12 bit in the ITU-T Recommendation
T.81 and ISO/IEC International Standard 10918-1.

As for the lossless process, it complies

with the lossless compression of Annex H following the same standard.

Features of “KJN-7EX_LSC”, a still image codec IP for the lossless/lossy processSupport 8, 10 and 12-bit depth for both Lossless and Lossy formats.

Enable 1600M Sample/sec (200 MHz) processing.

Obtain high-speed, small-scale and power-thrifty processing by Shikino’s original algorithms.

Achieve high compression performance by using our original Huffman table for 12-bit/10-bit JPEG.

SpecificationsCPU bus: 32 bitImage data bus: 96 bitCode data bus: 64/96/128 bit

Quantization table: 4 tables(RAM)Huffman table: 4 tables for DC and AC respectively (RAM) *1
