CMOS Image Sensor

One of the major decision to use a CCD or CMOS image sensor, while considering different format and designs under an imaging system depends highly on image quality and performance of an imaging system. Charge coupled devices (CCD) are in use since long mainly, due to their durability and enhanced imaging performance, whereas CMOS image sensors are been looked upon as a next gen product for image sensing. The second aspect to consider is cost. As CCD sensors are quite expensive over CMOS sensors, the feasibility becomes limited.

Overall, what important is, the nature of image sensing being addressed by a specific application. Commercially, the increasing importance of CMOS image sensors have enabled a greater competitive edge over CCD.

the market is highly driven by increase in use of smartphones and increasing developments in medical procedures. Optimum use of CMOS image sensors coupled with advances in technological applications seem to rise at a rapid rate. In addition, CCDs (Charged Coupled Devices) were preferably used for image quality and CMOS sensors served little. But the scenario is changing as CMOS image sensors have turned out to be much identical to CCDs in terms of efficiency.

Asia-Pacific regions are dominant in the global market scenario owing to rise in production of consumer appliances and medical industry. Extensive use of CMOS technology for medical procedures is likely to gain a positive traction in the near future. In addition, the regions are turning to digital devices and adopting IoT. Use of smartphones and other devices are likely to propel the use of CMOS image sensors in these devices.

Europe and North America lead the global market in the near future due to rise in demand for smartphones and rise in surveillance & security. Improvements in medical procedures displaying untapped opportunities in these regions are likely to propel the market growth.

Prominent players profiled in the CMOS image sensor market report include Canon Inc, Olympus Corporation, Sony Corporation, Hitachi Ltd, Karl Storz GmbH & Co Kg, Espros Photonics Corporation, Nikon Corporation, Fujifilm Holding Corporation, Teledyne Dalsa Inc and CMOSIS.

In the News:

As per the Industry News, Teledyne e2v has launched CMOS image sensor for barcode reading and high-speed scanning. Snappy 2 Megapixel is a novel CMOS image sensor aims for 2D scanning applications and barcode reading by having a full HD resolution, low-noise global shutter and highly economic decoding features. According to Gareth Powell, Marketing Manager at Teledyne e2v, Snappy 2M is the first series of innovative sensors particularly designed for barcode reading to enable mobile, fixed, handheld or fixed readers and automatic detection cameras exhibiting a better performance than ever.
