About the Committee

Chairman of the Standardization Committee:

Mr. Sadafumi TORII, Hamamatsu Photonics K.K.
 We have missions in the Standardization Committee to promote our standardization of the specification widely in the machine vision industry to be adopted in addition to coming up with the specification technically and taking a necessary step to standardize. JIIA has collaborated even with global standardization associations such as AIA, EMVA, CMVU, and VDMA to advance the understanding and use of vision and imaging technologies and to drive global expansion and growth effectively.

(1)The Standardization Committee and its standardization through promotion

 The Standardization Committee was organized specifically to form from time to time the Working Groups which are depending upon specifications to promote standardization underneath.
 As of today the Standardization Committee has managed three Technical Committees, five Working Groups taking care of camera interfaces, two Working Groups doing of camera protocols, and three Working Groups doing of imaging techniques. Each Working Group puts a team called the Task Force which serves and helps to standardize technical specifications for machine vision cameras and peripheral products in the industrial and medical market.

(2)Holding the Standardization Committee and coordinating among the Working Groups

 The Standardization Committee organized of the Technical Committees and the Working Groups respectively holds periodically meetings and coordinate among the Working Groups. Each Working Group is composed of specialists with expertise, makes the specification, and promotes our standardization. The specification is drafted by the Working Group respectively and coordinated among all the Working Groups.

1.Camera Interface Technical Committee(Chairperson: Mr. Hiroshi FUKUI, Daitron CO., LTD.)

1-1. CoaXPress Working Group

Group Chairperson:Mr. Masahito WATANABE, Adimec Electronic Imaging K.K
 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 6.25Gbps and also to control a camera simultaneously.
 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.

1-2. Optical Transmission Media Working Group

Group Chairperson:Mr. Hiroshi FUKUI, Daitron CO., LTD.
 There are huge demands for high speed interfaces even in the machine vision industry since emerging high speed imagers like not only CCD but also CMOS Image Sensor devices are well adopted 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 HSTM (CLHS). However we have recently seen problem with the boundary of speed due to physically a metallic cable so we believe in the strong demand for optical transmissions sometime soon.
 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, four types of the Optical Connectors have been proposed to AIA and EMVA by JIIA.

1-3. Camera Link Working Group

Group Chairperson:Mr. Hiroshi FUKUI, Daitron CO., LTD.
 Camera Link® is a serial communication protocol standard designed for computer vision applications and is highly populated. The standard is maintained and administered by AIA. JIIA has actively contributed to international efforts and promotions to add and implement Power over Camera Link (PoCL®) Technology and Power over Camera Link – Lite (PoCL-LiteTM) Technology which offers a smallerform 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 proposed to revise the CL standard to solve this problem. However, we found this problem is based on misunderstanding. JIIA- CLWG submitted a counter proposal to avoid confusion in the market. And, high speed CL on FPGA cameras increase in the market. Present Standard is not enough to support for high speed camera. AIA CL technical committee is considering version up for this issue. JIIA-CLWG watch the proceedings carefully.

1-4. GigE Vision Working Group

(This working group has been maintained by the Camera Interface Technical Committee.)
 GigE Vision® is the machine vision standard using the Gigabit Ethernet. This standard takes advantage of the 100m (max) cable length and the cost effective system on PC standard interface, and also offers the multiple cameras system. The activity for standardization is going on worldwide, then this WG works to introduce technical information and promote the standard.

1-5. USB3 Vision Working Group

Group Chairperson:Mr. 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.

2.Camera Protocol Technical Committee(Chairperson: Mr. Sadafumi TORII, Hamamatsu Photonics K.K.)

2-1. GenICam Working Group

(This working group has been maintained by the Camera Protocol Technical Committee.)
 GenICam™ is the camera control standard which defines the general programming interface. It offers the common programming circumstance independent on any kind of interface and camera models.
 The activity for standardization is going on worldwide, then this WG works to introduce technical information and promote the standard.

2-2. IIDC2 Working Group

Group Chairperson:Mr. Sadafumi TORII, Hamamatsu Photonics K.K
 IIDC2 is the camera control standard which achieves the independent method on any kind of interface and camera models. It takes advantage of simplicity and expandability. The activity of standardization is going on based on JIIA.. It brings cost effective design and production from common design platforms and broadened the range of product choice. This WG works to improve and promote the standard.

3.Imaging Technical Committee(Chairperson: Mr. Yutaka YAMAGUCHI, Toshiba Teli Corporation)

3-1. Lighting Working Group

Group Chairperson:Mr. Tsuneo SAKUMA, Kirin Techno-System Company, Limited
 The Lighting Working Group released the standard, “Fundamentals of Design and Specifications on Brightness of Optical Irradiation,” in 2013 and has worked on promotion activities of it.
 The Global Lighting Working Group consisting of AIA, EMVA and JIIA is collaborating to draft suggestions in regards to standardizations of the performance metrics of LEDs/Lasers, the lighting command and control, the photobiological safety and so on.

3-2. Lens Working Group

Group Chairperson:Mr. Yutaka YAMAGUCHI, Toshiba Teli Corporation
 The mission for the Lens Working Group is to standardize and promote the Technology for Machine Vision Camera Lens, Optical System, and its peripheral techniques. This Working Group has studied recent trends for Image Size Classes, Lens Mount Dimensions, and Optical Techniques where Area Sensors and Line Sensors with higher resolution and larger size are largely adopted in the machine vision industry.
 This Working Group is committed to proposing and standardizing a technical specification and guidance for the Optical Technology such as Lens Mount which brings in more considerate robustness, handy, and intuition for customers. The Working Group has enacted six lens mount standards. Currently, the lens mount standards are enacted as NF mount, NF-J mount, TFL & TFL-II mount, and S mount.

3-3. Camera Specification Working Group

(This working group has been maintained by the Imaging Technical Committee.)
 Today’s industrial cameras and peripheral products are packed with much more digital circuit than analog one. The Camera Specification Working Group has devoted a lot of effort to draft specification index, definitions, and measurement methods and also to promote standardization in the industry especially for the EMVA1288 Standard. The EMVA1288 Standard is an electronic measurement standard developed and introduced by EMVA to fill a need for a more uniform and standardized way of specifying the performance of image sensors and cameras. This Working Group has reviewed the effectiveness of the EMVA1288 Standard and considered our activities to specify its technical term in Japanese language and to expand into camera manufacturers and end users through promotion in Japan market.
