Patent number: 8355626Abstract: A lens-interchangeable camera includes a focus detector performing focus detection and a controller performing a drive control of a lens based on a defocus amount. The controller finishes focusing operation without driving the lens when the defocus amount is out a range of a first in-focus determination width, and performs the focusing operation when the defocus amount is out a range of the first in-focus determination width. The controller finishes the focusing operation without performing the focus detection again after completing the drive when the defocus amount is out a range of a second in-focus determination width, and performs the focus detection again after completing the drive when the defocus amount is out a range of the second in-focus determination width. The second in-focus determination width is set to be greater than the first in-focus determination width and be greater than or equal to a drive limit value.Type: GrantFiled: May 17, 2011Date of Patent: January 15, 2013Assignee: Canon Kabushiki KaishaInventors: Masanori Ishikawa, Masahisa Tamura, Tadanori Okada, Takumi Yamanaka, Kunihiko Sasaki, Yasushi Murakami, Shota Shimada, Takeya Nakayama
