20090040354 | IMAGE-PICKUP APPARATUS AND CONTROL METHOD THEREOF - An image-pickup apparatus | 02-12-2009 |
20110019015 | IMAGE PROCESSING APPARATUS AND METHOD CONFIGURED TO CALCULATE DEFOCUS AMOUNT OF DESIGNATED AREA - An image processing apparatus includes a focus detector configured to detect a focus state of a focus detection area by detecting a shift amount between a pair of image signals of an object image, a memory configured to store an image photoelectrically converted and output from an image pickup device, the focus detection area, and the image signals, a setting unit configured to set a designated area in the image stored in the memory, a calculating unit configured to calculate a defocus amount of the designated area using the pair of image signals corresponding to the designated area among the image signals stored by the memory, and a display unit configured to display the defocus amount of the designated area. | 01-27-2011 |
20130093939 | FOCUS ADJUSTMENT APPARATUS AND METHOD FOR CONTROLLING THE SAME - A focus adjustment apparatus includes an object detection unit configured to detect feature information of an object, a plurality of signal generation units configured to accumulate charges to generate and output a pair of image signals respectively, and a focus detection unit configured to control charge storage of the plurality of signal generation units and detect a focus based on a phase difference between a pair of image signals output from a first signal generation unit corresponding to the feature information of the object detected by the object detection unit, wherein if reliability of detection by the object detection unit is a first level which is higher than a second level, the focus detection unit sets charge storage time of the first signal generation unit longer than that in a case of the second level. | 04-18-2013 |
20130242173 | FOCUSING APPARATUS AND METHOD OF CONTROLLING FOCUSING APPARATUS - A focusing apparatus includes an image pickup element that includes a plurality of unit cells including a first pixel and a second pixel corresponding to a same microlens, a detector configured to detect a phase difference of an image signal of a first pixel group and an image signal of a second pixel group that correspond to a focus detection region, a focus controller configured to perform a focus control based on a detection result of the detector, an exposure controller configured to control an exposure value based on an output from the image pickup element, the detector detects the phase difference of an image signal generated by sequentially switching a plurality of focus detection regions, and the exposure controller controls the exposure value so as to be fixed until the detector completes a detection of the phase difference in the plurality of focus detection regions. | 09-19-2013 |
20130330068 | IMAGING APPARATUS, LENS APPARATUS, AND IMAGING APPARATUS CONTROL METHOD - In a camera system having an interchangeable lens and a camera body, a lens controller and a camera controller conduct timely change between a first communication method for a video shooting mode and a second communication method for a still-image shooting mode, and reciprocally communicated via a contact unit. The camera controller acquires time information in advance by an initial communication with the lens controller, and upon changeover from the first communication method to the second communication method, it interrupts communication after request information for changeover of the communication methods is transmitted to the lens controller, and initiates communication in the second communication method after elapse of a transition time indicated by time information. Upon changeover from the second communication method to the first communication method, the camera controller initiates communication in the first communication method after elapse of a transition time indicated by the time information. | 12-12-2013 |
20140022434 | IMAGE PICKUP APPARATUS, INTERCHANGEABLE LENS, AND CAMERA SYSTEM - An image pickup apparatus on which an interchangeable lens is removably mounted, includes an image pickup element configured to perform a photoelectric conversion of an optical image formed via the interchangeable lens, and a controller configured to control a power supply to the interchangeable lens mounted on the image pickup apparatus. When the mounted interchangeable lens is a first type interchangeable lens and a power is turned off, the controller performs an aperture control so as to change a first aperture state set in the interchangeable lens to a second aperture state and then stops the power supply to the interchangeable lens. When the mounted interchangeable lens is a second type interchangeable lens and the power is turned off, the controller maintains the power supply differently from a case where the mounted interchangeable lens is the first type interchangeable lens. | 01-23-2014 |
20140071336 | IMAGING APPARATUS AND METHOD FOR CONTROLLING THE SAME, AND LENS UNIT - In an imaging apparatus including a reset instruction unit configured to instruct a lens unit to reset an optical member thereof, a first communication system is used for communication for acquiring individual information of the lens unit, and a second communication system different from the first communication system is used for communication for instructing the lens unit to reset an optical member by a reset instruction unit. | 03-13-2014 |
20160105613 | LENS UNIT, METHOD FOR CONTROLLING LENS UNIT, IMAGING APPARATUS, AND METHOD FOR CONTROLLING IMAGING APPARATUS - A lens unit that can be attached to an imaging apparatus includes a display unit configured to switch and display information of a plurality of items, a lens control unit configured to control display on the display unit, and a first storage unit configured to store first information indicating an item selected from among items of information that can be displayed on the display unit. When the display on the display unit is turned off, the lens control unit stores in the first storage unit the first information corresponding to an item of information displayed on the display unit, and when the display on the display unit is turned on, the lens control unit displays, on the display unit, information of the item indicated by the first information stored in the first storage unit. | 04-14-2016 |
