-Providing long-distance transmission system by V-by-One® HS, directly connected to image sensor-
 

TOKYO (June 13, 2017) – THine Electronics, Inc. (JASDAQ: 6769), the global leader in high-speed serial interface and provider of mixed-signal LSI, has started, from June 2017, mass-production and delivery of V-by-One® HS new product “THCV241-Q,” which can be directly connected to MIPI® CSI-2 interface *1.

Nowadays, performance of image sensors has improved in terms of higher-definition and adaptation to HDR *2, and they are widely used for camera functions of mobile phones as well as various applications such as in-vehicle camera and security camera.  While MIPI® CSI-2 interface is commonly adopted for image sensors that output large volume of image data, distance of transmission of image data is limited according to the specification of MIPI® CSI-2 interface.  Therefore, there has been a problem that layout of an image sensor in an application is limited.

The V-by-One® HS new product “THCV241-Q” that THine has started mass-production makes it possible to transmit image data up to 15m by converting MIPI® CSI-2 interface to V-by-One® HS interface, which is the most remarkable feature of “THCV241-Q.”  By using “THCV241-Q,” image data of 8Mpixel 30fps at the maximum (or image data of 8Mpixel 60fps at the maximum) can be transmitted by V-by-One® HS with only one pair of shielded twisted pair wire or one coaxial wire (or one shielded twisted quad cable).  Accordingly, it is possible to provide a solution to limitation on transmission distance, which is a disadvantage of image sensors incorporating MIPI® CSI-2 interface, as well as to make transmission lines for large volume of image data with less number of cables.  Moreover, since “THCV241-Q” includes bridge function of GPIO/UART/two wire serial interface for controlling image sensors, it is possible to control operation of the image sensor of image data origin from the processer of image data transmission target.  Furthermore, it is also possible to supply power with the same cable.

“THCV241-Q”  follows AEC-Q100 Grade 2 *3, and can be used as a solution to allow free layouts and to reduce the weight by reduced number of cables to meet increasing requirements to incorporate several in-vehicle cameras in a vehicle.  In addition, “THCV241-Q” can handle large volume of image data output from an image sensor with HDR function and can transmit data of 2Mpixel 60fps by V-by-One® HS 1lane.  Moreover, since the V-by-One® HS technology is non-data-compression high-speed transmission system, time required for data compression and decompression is not necessary.  Therefore, it is possible to realize transmission of high-definition HDR image and reduction in transmission delay loss that are required for in-vehicle cameras for ADAS *4 necessary to achieve autonomous driving system.

“Since December 2016, THine has provided sample products and product evaluation support to customers in security camera, medical camera markets and etc. as well as in the market of in-vehicle camera which is expected to be incorporated in vehicles by more than 100,000,000 pieces in the next few years.  With mass-production of THCV241-Q, THine aims to contribute to improvement of added value of products of customers and to develop products that reflect needs of customers,” says Yasuhiro Takada, CEO of THine Electronics.

Method for rendering image to convert image with wide dynamic-range (ratio of light between the brightest part and the darkest part) to image with reduced contrast.

*3 AEC-Q100 Grade 2 (Automotive Electronics Council – Q100 Grade 2)
AEC is an organization for standardizing reliability of in-vehicle electric components established by American major automotive manufacturers and American major electric components manufacturers.  AEC-Q100 refers to standard for integrated circuit (IC), and Grade 2 means that temperature range of used components is -40C to +105C.

*4 ADAS (Advanced Driver Assistance System)
Term of system for detecting and preventing accidents in advance.
