20090041446 | IMAGE PICKUP APPARATUS - An image pickup apparatus is provided that can switch between an optical viewfinder mode for identifying an object using an optical viewfinder and a live view mode for identifying an image of an object using a monitor. The apparatus includes an auto-focus unit able to be configured in the optical viewfinder mode; and a control unit configured to switch, in a case where a mode for performing exposure control in association with an auto-focus result obtained by the auto-focus unit is set, when the optical viewfinder mode is switched to the live view mode, to a mode for performing exposure control not in association with the auto-focus result. | 02-12-2009 |
20100079617 | IMAGING APPARATUS AND METHOD FOR CONTROLLING THE SAME - An imaging apparatus includes an image sensor configured to capture an object image, a selection unit configured to automatically select a sensitivity of the image sensor from a predetermined selectable range, and an image processing unit configured to execute correction processing in which a signal of an image captured by the image sensor which has the sensitivity selected by the selection unit is amplified. When the image processing unit is set to execute the correction processing, the selection unit sets an upper limit of the selectable range lower, compared with the upper limit thereof when the image processing unit is not set to execute the correction processing. | 04-01-2010 |
20110050952 | IMAGE CAPTURING APPARATUS WITH IMPROVED CONTINUOUS SHOOTING SPEED - An image capturing apparatus includes a shutter spring which urges a shutter drive member for driving shutter blades, a shutter charge unit which is used to charge the shutter spring, and is switched between a fixed state in which a charge operation of the shutter spring is complete, and the shutter drive member is fixed and a released state, and a drive unit which drives the shutter charge unit. When a second determination unit determines that a switching ready state of a mirror from a mirror-down state to a mirror-up state is set when a first determination unit determines that a charge operation of the shutter spring is complete, the drive unit is controlled to drive the shutter charge unit to the released state without latch the shutter charge unit in the fixed state after the charge operation of the shutter spring is complete. | 03-03-2011 |
20110170848 | IMAGE PICKUP APPARATUS - An image pickup apparatus is provided that can switch between an optical viewfinder mode for identifying an object using an optical viewfinder and a live view mode for identifying an image of an object using a monitor. The apparatus includes an auto-focus unit able to be configured in the optical viewfinder mode; and a control unit configured to switch, in a case where a mode for performing exposure control in association with an auto-focus result obtained by the auto-focus unit is set, when the optical viewfinder mode is switched to the live view mode, to a mode for performing exposure control not in association with the auto-focus result. | 07-14-2011 |
20110194018 | IMAGE CAPTURING APPARATUS AND CONTROL METHOD THEREFOR - An image capturing apparatus capable of switching between an optical viewfinder and live view which involves periodically reading out an image signal out of an image sensor and sequentially displaying the image signal on a display unit, comprises a phase difference focus control unit that performs auto focus control using a phase difference detection method; a selection unit that selects one of a plurality of focus detection areas used for the auto focus control; an electronic zoom unit that changes an angle of view; and a control unit that causes the phase difference focus control unit to perform auto focus control by the phase difference detection method using the selected focus detection area if the selected focus detection area is located within the changed angle of view, otherwise not to perform auto focus control by the phase difference detection method using the selected focus detection area. | 08-11-2011 |
20130202282 | IMAGE PICKUP APPARATUS - After a shutter drive motor drives a shutter to a holding mode, if a first determination unit determines that a mirror is not ready to move to a mirror up mode, a control unit switches the shutter drive motor to a first braking mode. After the shutter drive motor is switched to the first braking mode, if the first determination unit determines that a mirror is ready to move to the mirror up mode before a second determination unit determines that the shutter drive motor is to be switched to a second braking mode, the control unit switches the shutter drive motor to an open mode until a predetermined period of time has elapsed since the first determination unit determined that the mirror was ready to move to a mirror up mode. | 08-08-2013 |
20130314569 | IMAGE CAPTURING APPARATUS AND CONTROL METHOD THEREFOR - An image capturing apparatus capable of switching between an optical viewfinder and live view which involves periodically reading out an image signal out of an image sensor and sequentially displaying the image signal on a display unit, comprises a phase difference focus control unit that performs auto focus control using a phase difference detection method; a selection unit that selects one of a plurality of focus detection areas used for the auto focus control; an electronic zoom unit that changes an angle of view; and a control unit that causes the phase difference focus control unit to perform auto focus control by the phase difference detection method using the selected focus detection area if the selected focus detection area is located within the changed angle of view, otherwise not to perform auto focus control by the phase difference detection method using the selected focus detection area. | 11-28-2013 |
20140016025 | LENS APPARATUS AND IMAGE PICKUP APPARATUS CAPABLE OF CONTROLLING APERTURE STOP - A lens apparatus includes an aperture stop unit that adjusts light intensity, a terminal configured so that a voltage is applied in a state of connecting to an image pickup apparatus, a drive circuit that drives the aperture stop unit, and a controller that controls the drive circuit, the controller controls the drive circuit in a drive mode that drives the aperture stop unit from a first position to a second position without driving the aperture stop unit to an open position. | 01-16-2014 |
20140327811 | IMAGE PICKUP APPARATUS, METHOD OF CONTROLLING IMAGE PICKUP APPARATUS, AND NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM - An image pickup apparatus includes an image pickup element configured to photoelectrically convert an optical image, and a controller configured to control a drive of a focus lens based on a signal outputted from the image pickup element and control a frame rate to drive the image pickup element, and the controller is configured to detect an in-focus position based on a signal outputted from the image pickup element which is driven at a first frame rate, and to switch the frame rate of the image pickup element to a second frame rate lower than the first frame rate while performing a first operation to drive the focus lens to the in-focus position. | 11-06-2014 |
