Company profile
Vieworks Co.，Ltd. develops industrial cameras using optical-design technology for machine vision, a core field of industrial automation in which the camera functions as the system's eye. For quality control and stabilization of inspection objects, the company concentrates on camera technologies that capture higher resolution at faster speeds. In 2010, Vieworks Co.，Ltd. launched an ultra-high-resolution industrial camera using pixel-shift technology, which moves beyond the physical limitation of the image sensor and can reveal an error as small as a single tiny pixel. Its thermoelectric cooling technology can lower sensor temperature to as much as 20 degrees below ambient temperature so that image quality remains uniform. Vieworks Co.，Ltd. developed its hybrid TDI, or time delayed integration, sensor for the first time in the world, combining the strengths of CMOS and CCD sensor approaches, and the company describes the resulting performance as top in the industry. The company's imaging-development record also includes a 152-megapixel sensor described as having the highest resolution available from a single sensor. Vieworks Co.，Ltd. has received product-design recognition for its cameras, including Red Dot and iF design awards. The company combines experience and technical knowledge in sensors, optics, and applications to propose optimized machine-vision systems for different application requirements. The Vieworks name combines the words 'View' and 'Works' and is presented as an expression of the company's intention to contribute to society through imaging solutions. Over the past two decades, Vieworks Co.，Ltd. has developed imaging technologies for digital X-ray detectors, industrial cameras, and in vivo imaging systems. Drawing on that accumulated experience, the company describes itself as a specialized imaging-solution supplier serving the global market. Vieworks Co.，Ltd. treats investment in people as investment in fundamental capability and supports employees in leading projects regardless of position. It also links a self-motivated organizational culture with the achievements that have shaped the company and with its continuing development of imaging technology. As markets change and customer requirements diversify, Vieworks Co.，Ltd. responds through continuous technological development and the creation of new imaging products. The company's machine-vision organization combines product development with customer-support resources, a download center, a global network, and partner relationships for users of its industrial imaging products. Across these activities, Vieworks Co.，Ltd. positions its sensor, optics, application, and system knowledge as the basis for supplying cameras and imaging solutions rather than treating the camera as an isolated component.
Exhibits
Vieworks Co.，Ltd. supplies an industrial-camera portfolio that includes Area Scan Cameras, TDI Line Scan Cameras, Line Scan Cameras, accessories, software, and industrial lenses. Its industrial-lens range lists the VEO JM Series, VEO JK Series, VEO CS Series, VEO YK Series, VEO HJ Series, and VEO MH Series. The company's machine-vision technology base brings optics, mechanics, electronics, and software together in house, supporting in-house design and quality control across those core disciplines. For applications requiring higher sensitivity, TDI line-scan cameras use multiple line-scan stages and can provide up to 256 times higher sensitivity than a standard line-scan camera that scans once. To improve TDI line-scanning performance, Vieworks Co.，Ltd. developed a Hybrid TDI line-scan sensor whose CCD pixel structure is implemented with CMOS technology and supports ultra-high-speed image capture with up to 256 times greater sensitivity. The Hybrid TDI architecture combines a light-sensitive CCD-based TDI pixel array with CMOS readout electronics so that the sensor can draw on useful characteristics of both CCD and CMOS approaches. The technology description contrasts conventional CCD advantages such as better image quality and higher signal-to-noise ratio with drawbacks such as higher power consumption and cost, while conventional CMOS is described as faster and lower-power but noisier. Pixel-shifting technology enables a camera to acquire ultra-high resolution beyond the physical limitation of its image sensor and can reduce the need to deploy multiple cameras for extremely high-resolution applications. Because the image-sensor stage must move precisely by one-half or one-third of a pixel even after very large numbers of movements, system reliability is a key requirement for pixel-shifting cameras. Vieworks Co.，Ltd. applies nano-stage technology in its pixel-shift system to obtain ultra-high resolution, true-color images, and improved fill factor. The VN Series and VNP Series are identified as camera families associated with the company's pixel-shifting technology. For long-exposure imaging, thermoelectric cooling uses the Peltier effect to lower temperature and reduce noise that would otherwise increase as the sensor becomes hotter. Vieworks Co.，Ltd. designs a dedicated heat-dissipation structure from internal components through the housing so that operating-sensor temperature can be maintained at up to 20 degrees below ambient temperature. Its cooling-camera design also uses a heating structure to remove moisture that can occur on the cold surface of the Peltier element while retaining a sturdy, compact camera form. The VP Series and VNP Series are listed in connection with the company's thermoelectric-cooling camera technology. The Vieworks Novel Optical Inspection Solution is designed for flat-panel-display inspection, and every component is optimized to detect submicron defects. The inspection solution is specifically configured to identify very small defects in flat-panel-display inspection where high detection capability is required. Its camera element is a high-resolution TDI line-scan camera from the VT Series, while the lens element is a VEO Series high-performance lens codeveloped with Schneider. An auto-focus module provides real-time tracking to improve automatic focusing during inspection. The optical-system setting unit supports rolling and yawing adjustments so the inspection optics can be aligned for the target configuration. Coaxial illumination supports line fiber and Vieworks Optimized Illumination, forming one of the controlled-lighting options in the inspection system. Diffuse illumination is also supported to improve detection of particles and scratch defects on inspected surfaces. Together, the VT Series, VEO Series, focusing module, optical-setting unit, and coaxial and diffuse illumination form an integrated optical-inspection configuration rather than a camera-only offering. Across the line-scan, pixel-shift, cooling, and flat-panel inspection technologies, the portfolio addresses industrial inspection requirements that depend on sensitivity, resolution, thermal stability, precise optical alignment, and controlled illumination. The company's listed machine-vision technology themes include the Vieworks Hybrid TDI Line Sensor, Pixel Shifting Technology, Thermoelectric Cooling Technology, and the Vieworks Novel Optical Inspection Solution.
