The RGBW coding function improves sensitivity by adding white pixels to RGB (red, green and blue) pixels so that clear images can be taken even in a dark room or during nighttime hours. The HDR movie function sets two kinds of exposure conditions inside pixels at the time of shooting a movie and applies signal processing to the images taken under the conditions so that pixels with a wide dynamic range are created.

The ISX014 comes with an image quality adjustment function and other functions that process camera signals.

Sony plans to ship samples of the IMX135, IMX134 and ISX014 in January 2013, March 2013 and October 2012, respectively, at prices of ¥1,500 (approx US$18.89), 1,000 and 1,200 (including tax).

Furthermore, Sony will release three modules, each of which is equipped with one of the three models of the new CMOS sensor and a lens unit having an autofocus mechanism. The "IU135F3-Z," "IU134F9-Z" and "IUS014F-Z" modules come with the IMX135, IMX134 and ISX014, respectively.

The IU135F3-Z has a high-resolution lens whose F value is 2.2. The IU134F9-Z, which measures 8.5 x 8.5 x 4.2mm, features a volume 14% less than Sony's existing product. The IUS014F-Z comes with embedded autofocus and image quality adjustment functions.

The shipments of the IU135F3-Z, IU134F9-Z and IUS014F-Z will begin in March 2013, May 2013 and November 2012, respectively, with sample prices of ¥8,000, 5,000 and 6,000 (including tax).

At the press conference that took place Aug 20, 2012, Tomoyuki Suzuki, Sony's corporate executive officer and EVP, president of Device Solutions Business Group, president of Core Device Development Group, who supervises the company's device business took the podium.

"Image sensors play an important role in Sony's core business," he said. "Our CMOS sensors have almost reached a point where they are superior to human eyes. And we will pursue further advances. We will be engaged in the image sensor business with a resolution to change Sony with devices."
