Patent number: 8194995Abstract: A camera auto-focuses using computed blur differences between images of a three-dimensional scene. The camera computes the blur difference between two images of the scene acquired at two different picture numbers. The camera uses the computed blur difference to predict a third picture number, where the camera uses the third picture number to auto-focus a camera lens on the scene.Type: GrantFiled: September 30, 2008Date of Patent: June 5, 2012Assignees: Sony Corporation, Sony Electronics Inc.Inventors: Earl Quong Wong, Makibi Nakamura, Hidenori Kushida, Soroj Triteyaprasert, Yoshihiro Murakami, Pingshan Li, Mamoru Sugiura
