iOS 4.1 HDR photography comes from Imsense acquisition?

iOS 4.1 includes HDR photography for iPhone 4, but did Apple roll the technology themselves or did they buy it along with UK company Imsense Ltd? MacRumors has done some sleuthing and they think the latter:

According to a note on the website of Braveheart Ventures, which backed imsense, the company was acquired by "an undisclosed trade buyer in July 2010". According to a press release from Braveheart, it received £342,000 for its minority stake in imsense, more than doubling its original £150,000 investment in two years.We also note that imsense Director of Engineering Alexis Gatt left the company in July 2010, just as it was being acquired, to become senior engineer at Apple. Together, the information suggests that imsense may have been acquired by Apple, although no definitive evidence has yet been uncovered.

Their iPhone app, imphoto, is also gone from the App Store, and desktop versions of their software have been discontinued.

Does this continue Apple's recent tradition of small, technology and talent focused acquisitions?
