CMOS sensors are now used in cellular phones and other mobile devices, sales of these devices have been increasing rapidly. Furthermore, demand for CMOS sensors has been increasing in fields that require high-speed imaging functions, such as digital single-lens reflex cameras. While CMOS sensor advantages over CCD include lower power consumption and higher speed, their main strength is in the possibilities for system integration, since analog and digital circuits can be integrated. CMOS sensor can achieve high-speed characteristics that could not be achieved with CCD technology and can provide superb image quality that surpasses that of CCDs by taking advantage of these characteristics.

Sony has now implemented a CMOS sensor that achieves both high-speed image readout and improved image quality by taking advantage of these CMOS sensor characteristics and integrating column-parallel A/D converters on the same chip. This CMOS sensor can read out 2.8M-pixel images at the speed of 180 frame/s. Furthermore, this device achieves noise levels comparable to those of CCD image sensors at the same time as providing this high-speed readout. This article presents the high-speed imaging technology based on column-parallel A/D conversion and the noise reduction technology used in this device.

The PMA show, or Photo Marketing Association, continues its yearly tradition of maintaining a network of photo imaging as well as the experience and know-how of the industry. The PMA represents 20,000 members from over 100 countries, who are all active within the imaging industry. As a reflection of the changes in the market, the PMA organization has also changed and has become more diverse. Nowadays, the member group consists of representatives coming from photo retail, manufacturers, commercial photo labs, professional sports and news photography, in addition to small album print suppliers and photo processing centers. The PMA 2012 Trade show focuses on an industry which is heavily affected by the unstable situation of the global financial economy. However, whether the latter will also stand in the way of the innovation and product introductions, remains to be revealed by the PMA International Convention & Trade Show in Anaheim Convention Center (California, US).
