Patent application number | Description | Published |
20080198259 | Auto focus system - The auto focus system obtains focus information on a lens-interchangeable camera body of a TV camera and sends the focus information to a lens apparatus mounted on the camera body. The lens apparatus controls an auto focus based on the focus information. It is thereby possible to control the focus on adequate conditions according to optical specifications of the lens apparatus and so on. | 08-21-2008 |
20100074606 | AUTO FOCUS DEVICE - Disclosed is an auto focus device that automatically and easily sets an AF frame to a focus range desired by a cameraman in an AF system. | 03-25-2010 |
20100214424 | SHAKE DETECTING SENSOR AND IMAGE BLUR CORRECTING DEVICE - A shake detecting sensor includes: a plurality of shake detecting sensors that detects a shake; and an adder circuit that adds shake signals output from the plurality of shake detecting sensors. A signal added by the adder circuit is output as a shake signal output from one sensor. | 08-26-2010 |
20100254690 | AUTOFOCUS SYSTEM - An autofocus system includes: an image pickup unit that takes a subject image formed by an optical system; a target subject detection unit that detects a target subject, which is previously registered as an autofocus target, in a photographing image taken by the image pickup unit; a lens-to-subject distance calculation unit that calculates a lens-to-subject distance to the target subject based on information on a photographing angle of view depending on a focal length of the optical system, a size of the target subject in the photographing image, and a size of the target subject in real space; and a rough AF unit that controls a focus of the optical system so as to bring into focus the subject which is located at the lens-to-subject distance calculated by the lens-to-subject distance calculation unit. | 10-07-2010 |
20110158624 | AUTOFOCUS SYSTEM - An autofocus system includes: a focus operating device which performs focusing in a shooting screen of a camera; a best focus range detecting device which detects a range of a best focus state from the shooting screen representing the result of the focusing performed by the focus operating device; a face detecting device which detects a range of a human face from the shooting screen; an AF frame automatic setting device by which, when a human face exists in the range being in the best focus state in the shooting screen, the position of an AF frame representing the range of an AF area that is the range to be focused by autofocus in the shooting screen, is automatically set to a face frame representing the range of the human face; and an AF frame automatic tracking device which automatically tracks a subject in the set AF frame. | 06-30-2011 |
