Shikino Launches Still Image Encoder IP Obtaining High-speed Image Processing in 16X speed (16 data/clock)

Featured "World's Highest" 16X speed to Achieve Image Processing with High Bit Depths (10-bit/12-bit)

UOZU -- April 1, 2014 -- Shikino High-Tech Co., Ltd. ("Shikino") today announced that it has launched a new still image encoder IP, "KJN-8EX_ENC", and commences sales today, April 1. 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 first image processing performance, 16X speed (16 data/clock), in the JPEG compression 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.

Achieve ultra-high speed JPEG compression

KJN-8EX_ENC makes it possible to achieve 16X speed (16 data/clock), the world's highest speed, as the image processing performance of the JPEG compression (data rate). This product is most suitable for digital cameras and smart phones requiring high-speed continuous shooting performance, and broadcasting equipments for the Ultra High Definition Television Broadcasting for next-generation 8K4K images.

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_ENC attains high image quality. This KJN-8EX_ENC 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.

Achieve low power consumption

Shikino's original implementing technology minimizes gate amounts following high-speed image processing and reduces 30% 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_ENC, 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: Compress 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_ENC" 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.
