 CoaXPress® is intended technically to transmit digital signals over a coaxial cable. This technology using only one coaxial cable for both an industrial camera and a frame grabber allows to transmit data up to 12.5Gbps and to control a camera simultaneously. CoaXPress over fiber Protocol option realizes higher speed and long distance transmission using standard optical fiber internet technology.
 This Committee serves direct activities to draft technical specifications and documentations for standardization of CoaXPress®, manages the electric conformance test and interoperability test to approve the specification, and drives global expansion and growth for the specification and qualified products through promotion.

Embedded Vision I/F Working Group

Group Chairperson : Miho Akahide , Sony Semiconductor Solutions Corporation
 In accordance with the trend of IIoT and Industrie 4.0, JIIA and G3 promote the standardization of Embedded Vision. In 2018, a new standard initiative “emVision” hosted by EMVA has started to develop Embedded Vision Interface Standard.
 This working group promote “SLVS-EC (Scalable Low Voltage Signaling with Embedded Clock)” Standard. SLVS-EC is an interface between image sensors and processors and one of the important element of emVision. We have released SLVS-EC standard Version 2.0, the data rate is up to 5Gbps/lane.
 JIIA will take an active role in emVision and share the latest status of Embedded Vision with this working group and appeal to G3.

Optical Transmission Media Working Group

Group Chairperson:Yoshinori ARAI, Fujikura Solutions Ltd.
 There are huge demands for high speed interfaces even in the machine vision industry.
 Recently, CMOS Image Sensor devices are becoming major in global markets. Global Coordination of Machine Vision Standardization between AIA, EMVA and JIIA helped to propose new specifications for high speed interfaces such as CoaXPress® (CXP) and Camera Link HS™ (CLHS).
 However we have sometimes seen problem with the boundary of speed due to physically a metallic cable.
 We believe in the strong demand for optical transmissions in the near future. The Optical Transmission Media Working Group has started to study potential new requirements to implement smaller size cameras and to take into robust systems for user-friendliness, 4 types of the Optical Transmission Media have been proposed to AIA and EMVA by JIIA.
 2 types already have been released as the JIIA standard officially.
 The development for 2 types of others were stopped.
 After that, we received a new proposal. This is now on the way to a goal.

Camera Link Working Group

(This working group has been maintained by Camera Interface Committee)
 Camera Link® is the first digital interface standard designed for machine vision applications and is highly populated. The standard is maintained and administered by AIA. JIIA has actively contributed to improve this standard.
 JIIA-CLWG added Power over Camera Link (PoCL®) Technology and Power over Camera Link – Lite (PoCL-Lite™) Technology which offers a smaller form factor for low-cost solutions in the specifications.
 JIIA-CLWG received a report regarding HDR/SDR connector problem from AIA CL member at the IVSM in 2014 fall. They revised the CL standard to solve this problem in version 2.1.
 And, in addition to this, recently, high speed CL on FPGA cameras increase in the market. But present Standard is not enough to support for high speed camera.
 AIA CL technical committee is considering version up for this issue as the ver3.0.
 In this case, there are 2 big changes. One is conformity to GenICam standard.
 The other is Inplementation of the plug Festa. However, this ver3.0 is not made up finally. JIIA-CLWG watch the proceedings carefully.

GigE Vision Working Group

(This working group has been maintained by Camera Interface Committee)
 “GigE Vision®” is a machine vision standard using Gigabit Ethernet.
 It can easily create long distance transmission of 100m, low cost system by using PC standard interface, and multi-camera system.
 Standardization is managed by AIA and its activities are achieved as an international effort as G3.
 This Working Group are disseminating the standardized specification in cooperation with the GenICam working group.

USB3 Vision Working Group

Group Chairperson:Hiroki NAGAO, NEC Platforms, Ltd.
 USB3 Vision™ is the machine vision standard using USB 3.0 interface.
 USB3 Vision takes advantage of the high data transfer rate of 5 Gbps and the cost effective system on PC standard interface.
 The activity for standardization is going on worldwide, then this WG works to introduce technical information and promote the standard.
 The Type-C connector standard with a locking mechanism is also a result. Currently, the latest USB standard is “USB4”, and the transfer speed reaches up to 40 Gbps with the Gen3 x 2 specification.
 The USB3 Vision standard is also being considered to support the latest standards in order to support higher resolution / higher frame rates of image sensors.

Connector & Cable Certification Working Group

Group Chairperson:Susumu NAKAGAWA, Hirose Electric Co., LTD.
 The use of MV systems will increase as the automation of factories and the use of robots advances further with “Industry 4” and “MiC2025”.
 As a result, there are concerns that there will be many quality problems that have not been seen so far. This could result in obstruction of the development of the MV industry.
 As a preventive measure, the Connectors and Cables Certification Committee has established a certification system for connectors and cables that meet the MV standards, and is promoting activities to prevent quality problems in the market, both domestic and overseas.

Next Generation Vision network sub Working Group

Group Chairperson:Hiroshi TOTSUKA, LeImac Ltd.
 In 2014, Germany proposed Industrie 4.0. Since then, Manufacturing site has been a smart factory. AI became popular in the process of inspecting products. As a result, Automation has advanced to a high degree. So, Image Processing was re-recognized as a necessary item.
 This activity is to create an environment where Vision System can be seamlessly connected to MECHATRLINK. MECHATROLINK is a field network used for Motion Systems. This activity is a collaboration with MECHATRLINK MEMBERS ASSOCIATION (MMA).
 We are working on standardization to solve each other’s challenges. The Motion field is the basis of systems in the evolving manufacturing environment. We will consider that the Vision System can function effectively in the Motion field. The next step is to create new value.

High Fidelity Color Standard SWG

Group Chairperson : Yuzo Hisatake, National University Corporation Shizuoka University
 In collaboration with the Japanese national committee for standardization of next-generation high-color-fidelity imaging-system of Shizuoka University, Our sub-working group (Standardization of high-fidelity color imaging system sub working group: HFCS-SWG) has been working on establishing a standard for high fidelity color reproduction systems that reproduce colors in a colorimetric manner (equalize XYZ3 stimulus values).
 This standard is expected to be used in various fields where faithful color reproduction is required, such as factory quality inspection, medical fields, electronic commerce (mail order) and etc.. We also promote the importance of standardization on high-color-fidelity imaging system through exhibitions and seminars to raise awareness of diverse users. Furthermore, we will work on not only for a JIIA standard but also for de-jure standards (International Standards such as ISO and/or IEC) with the aim of spreading such faithful color reproduction technology all over the world.
