Shikino Launches Still Image Decoder IP Obtaining "World-class speed" 16X faster image processing

Achieve Speeding up, High image quality and Low power consumption by Shikino’s original decoding technology

UOZU -- March 2, 2015 -- Shikino High-Tech Co., Ltd. (“Shikino”) today announced that it has launched a new still image decoder IP, “KJN-8EX_DEC”, and commenced sales on February 27. 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 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.

Speeding up : Achieve ultra-high speed JPEG compression/decompression
KJN-8EX_DEC makes it possible to achieve 16X speed (16 data/clock), the world’s highest speed, as the image processing performance of the JPEG decompression (data rate). This product and combination with KJN-8EX_ENC(April 1,2014 released) is most suitable for digital cameras and smart phones requiring high-speed continuous shooting and display performance, and broadcasting equipments for the Ultra High Definition Television Broadcasting for next-generation 8K4K images.
High image quality : Achieve ultra-high definition images with high bit depths
In addition to the general 8-bit depth in JPEG, the high bit depth feature (10-bit/12-bit) added in KJN-8EX_DEC attains high image quality. This KJN-8EX_DEC technology is optimally applied to highly advanced medical equipments, aviation/aerospace equipments, broadcasting equipments for the Ultra High Definition Television broadcasting that require color reproducibility and high gradation.
Low power consumption : Achieve communized architecture design
Shikino’s original implementing technology minimizes gate amounts following high-speed image processing and reduces 45% of the power consumption, compared to our existing company’s products. This is optimal for portable devices (e.g., tablet PCs) and battery drive devices (e.g., digital cameras).

This brand-new product, KJN-8EX_DEC, is anticipated to meet the market demands for digital cameras, smart phones, tablet PCs, broadcasting equipments, medical equipments, aerospace equipments and so on. Also, Shikino’s “KJN series” provides customers with the IP products featuring 1X to 16X JPEG image processing. We Shikino will continuously develop and expand our lineups to satisfy the requests from more customers.

*16X speed: Decompress 8K4K images with 60 frames per second in real time (240 MHz clock)
*Gradation: A unit expressing color and brightness
Number of colors: Cubed gradation numbers in the RGB color model
8 bits: 256 gradations per color/16.77 million colors (8 bits applied to PC)
10 bits: 1024 gradations per color/1.07 billion colors
12 bits: 4096 gradations per color/68.71 billion colors

About JPEG Extended DCT-based process
The 12-bit JPEG (Extended DCT-based process) employed in “KJN-8EX_DEC” is an international standard to extend general 8-bit JPEG to 12 bits in the ITU-T Recommendation T.81 and ISO/IEC International Standard 10918-1.
