Pocket-lint and I-Micronews report that Sony has announced the development of a "coin-sized" HD camera module for use in security and industry. The 8.3MP module footprint is just 9.5 x 7.1mm, although it has some added stuff on the flex cable:
The MCB1172 module from Sony Europe's Image Sensing Solutions Division is capable of delivering 720p, 30fps video and includes AF, video stabilization and face detection. It also features a high sensitivity mode and a slow-motion mode, delivering 120fps as well as the option of 16x zoom. The module is reported to be available for mass production, products with the module in will likely hit the business markets later this year.
The strange thing is that I'm unable to find any official word from Sony.
