The US Trademark and Patent Office on Thursday published the latest 33 patent applications filed by Apple, which has filed 55 patents as of July, with a third of the patents filed this month. The patents cover a variety of areas, and Apple intends to turn some of them into features in its popular iPhone and iPod touch players. Two of the most eye-catching of these patents are closely related to cameras: one patent is for object recognition and the other patent is for face recognition.
