20080198257 | IMAGE-PICKUP APPARATUS - An image-pickup apparatus includes an image-pickup element photoelectrically converting an object image, a light-receiving sensor outputting a signal in accordance with a phase difference between a pair of object images, and a controller performing first focus control of controlling drive of a focus adjusting member based on a focus evaluation signal representing a contrast state of a video signal produced with the image-pickup element and second focus control of controlling drive of the focus adjusting member based on the signal in accordance with the phase difference. The controller stops the second focus control or switches focus control from the second focus control to the first focus control in response to a predetermined change found in the focus evaluation signal during the second focus control. The apparatus is capable of achieving an in-focus state smoothly and accurately with a hybrid AF. | 08-21-2008 |
20090168200 | LENS POSITION CONTROL APPARATUS, IMAGING APPARATUS, AND CONTROL METHOD - It is provided an imaging apparatus including a plurality of motors configured to be driven to move lenses in synchronous with a drive pulse, a position detection unit configured to detect one of positions of the lenses moved by the driving of the plurality of motors, an operation unit configured to perform an output corresponding to an operation in response to the operation by a user, and a controller configured to receive the output from the position detection unit and control the plurality of motors. The controller supplies the number of drive pulses calculated based on a target position for moving the lens calculated based on the output from the operation unit and a lens position detected by the position detection unit. | 07-02-2009 |
20110063738 | LENS POSITION CONTROL APPARATUS, IMAGING APPARATUS, AND CONTROL METHOD - It is provided an imaging apparatus including a plurality of motors configured to be driven to move lenses in synchronous with a drive pulse, a position detection unit configured to detect one of positions of the lenses moved by the driving of the plurality of motors, an operation unit configured to perform an output corresponding to an operation in response to the operation by a user, and a controller configured to receive the output from the position detection unit and control the plurality of motors. The controller supplies the number of drive pulses calculated based on a target position for moving the lens calculated based on the output from the operation unit and a lens position detected by the position detection unit. | 03-17-2011 |
20110235188 | IMAGE PICKUP LENS, IMAGE PICKUP APPARATUS, AND LENS CONTROLLING METHOD - An image pickup lens includes a controller and a manipulator position detector configured to detect a position of a manipulator configured to accept a manipulation used to move the lens. When the manipulation of the manipulator becomes valid and a difference between the position of the manipulator when the manipulation of the manipulator is invalid and the position of the manipulator when the manipulation of the manipulator is valid is equal or smaller than a threshold, the controller controls a movement of the lens from an initial position that is the position of the lens when the manipulation of the manipulator is invalid. When the manipulation of the manipulator becomes valid and the difference is larger than the threshold, the controller controls a movement of the lens from an initial position that is the position of the lens corresponding to the manipulator's position detected by the manipulator position detector. | 09-29-2011 |
20110243538 | IMAGE PICKUP APPARATUS AND METHOD OF CONTROLLING THE SAME - An image pickup apparatus detects a subject based on an image signal output from an image sensing unit and acquires a size of the detected subject. The image pickup apparatus performs an automatic zooming operation such that a zoom lens is driven so as to increase or decrease the size of the subject so that the size of the subject becomes equal to a reference size of the subject. In a case where the difference between the size of the subject and the reference size has increased beyond a predetermined threshold value and the position of the zoom lens has reached a wide angle end or a telephoto end, the image pickup apparatus resets the reference size to be equal to the current size of the subject. | 10-06-2011 |
20120307134 | IMAGING APPARATUS, CONTROL METHOD FOR THE IMAGING APPARATUS, LENS UNIT, AND CONTROL METHOD FOR THE LENS UNIT - An imaging apparatus on which a lens unit having a photographic optical system including a focus lens and capable of controlling driving of the photographic optical system based on information received from the imaging apparatus is mountable includes a filter driving unit configured to insert or retract an optical filter on an optical path of the photographic optical system, a detection unit configured to detect an insertion state of the optical filter, and a control unit configured to calculate, based on a change of the insertion state of the optical filter detected by the detection unit, a movement amount of an image forming position of an object image, and to transmit information on the movement amount of the image forming position of the object image and information indicating the insertion state of the optical filter to the lens unit. | 12-06-2012 |
20140198229 | IMAGE PICKUP APPARATUS, REMOTE CONTROL APPARATUS, AND METHODS OF CONTROLLING IMAGE PICKUP APPARATUS AND REMOTE CONTROL APPARATUS - An image pickup apparatus includes an image pickup device which generates an image signal by performing photoelectric conversion on an optical image via an optical system, an object detector which detects a plurality of object images based on the image signal obtained from the image pickup device, an identification information generator which allocates identification information to each of the object images, a communicator which sends the image signal and the identification information allocated to each of the object images to an outside of the image pickup apparatus, wherein the communicator is capable of receiving identification information of an object image relating to the sent identification information of the object image, and a controller configured to specify a main object image among the object images detected by the object detector based on the received identification information. | 07-17-2014 |
