The markets for smartphones and tablets increasingly require smaller cameras but with much higher resolution. With a 1.12 micrometer pixel size contributing to a smaller chip size, Toshiba’s new sensor achieves 20 megapixel images at its highest level and realizes 6mm z-height camera modules for smartphones and tablets.

The new sensor also offers a much improved frame rate of 22fps, 1.8 times faster than that of Toshiba’s previous 20-megapixel sensor[2].

A reference module incorporating the new product is currently under preparation and will be available from September 1.

With the launch of the new 20-megapixel CMOS image sensor, Toshiba commits to meeting demands for higher resolution images for smartphones and tablets.
