20080199173 | CAMERA, ACCESSORY, AND CAMERA SYSTEM - A camera includes a camera control unit configured to acquire information on an accessory mounted on the camera by performing communication with an accessory control unit included in the accessory and to control a photographing operation based on the information on the accessory. When the camera control unit acquires, from the accessory control unit, first information that is required prior to start of photographing and second information that is required prior to generation of image data after the start of photographing, if the camera control unit determines that a photographer has performed an operation to start a photographing operation during a period in which the camera control unit is performing communication to acquire the second information, the camera control unit executes a photographic sequence in priority to acquiring the second information and thereafter acquires the second information. | 08-21-2008 |
20090228727 | METHOD AND PROGRAM FOR SETTING MICROPROCESSOR POWER SUPPLY VOLTAGE - A determining unit determines the state of the microprocessor. A setting unit sets a power supply voltage to be supplied to the microprocessor according to the state of the microprocessor determined by the determining unit. A power supply circuit supplies the power supply voltage set by the setting unit, to the microprocessor via a power supply line. The determining unit determines repeatedly the state of the microprocessor at preset timing, and the setting unit resets the power supply voltage every time the determination is performed by the determining unit. | 09-10-2009 |
20100309365 | IMAGE PICKUP APPARATUS HAVING IMPROVED CONTRAST AUTOFOCUS ACCURACY - An image pickup apparatus includes an image pickup device that includes a plurality of focus detection pixels, a phase difference detection type of a first focus detector, a contrast detection type of a second focus detector, and a controller. The controller is configured to allow the second focus detector to continue the focus detection when the shift amount detected by the first focus detector is larger than a threshold even when the second focus detector detects the lens position corresponding to the peak of the contrast value, and to move the image pickup lens to a lens position that provides a peak of a contrast value detected by the second focus detector when the shift amount is the threshold or smaller. | 12-09-2010 |
20100315456 | PRINTING APPARATUS AND PRINTING METHOD - In an ink jet printing apparatus for scanning a print medium with a printing head and printing an image thereon, the printing head includes a plurality of ink ejection port arrays. The ink ejection ports in each of the arrays are arranged in a direction crossing a scanning direction of the printing head relative to the print medium. An allowable recording rate given to at least one of the ejection port arrays behind an ejection port array located at the front in the scanning direction is set lower than that given to the one located at the front. As a result, a printing apparatus capable of suppressing a throughput speed thereof and adhesion of ink mists to a formation face of the ejection ports can be provided. | 12-16-2010 |
20110050981 | FOCUSING APPARATUS - A focusing apparatus includes a setting unit configured to set a focus detection area to be focused among a plurality of focus detection areas, a memory configured to store focus correction information based on a focusing status of a focus lens in each of the focus detection area to be focused and another focus detection area, a focus detection unit configured to detect the focusing status of the focus lens in the other focus detection areas, and a focusing unit configured to move the focus lens for focusing based on the focusing status of the focus lens detected in the other focus detection area. The focusing unit corrects the focusing status of the focus lens detected in the other focus detection area based on the focus correction information stored in the memory and achieves focusing. | 03-03-2011 |
20110091191 | IMAGING APPARATUS AND FOCUS CONTROL METHOD FOR THE IMAGING APPARATUS - An imaging apparatus which includes a focus detection unit performing focus detection in a contrast system, and a display unit displaying the image obtained from an imaging unit in live view display is provided. The imaging apparatus includes a setting member setting a contrast AF calibration mode, a calibration amount obtaining unit for obtaining a difference amount between a focus position selected by a photographer and an in-focus position by the focus detection unit as a contrast AF calibration amount when the focus position is selected by the photographer in the contrast AF calibration mode, a storage unit storing the contrast AF calibration amount, and a focus control unit performing in-focus control by adding the contrast AF calibration amount to the in-focus position by the focus detection unit at the time of shooting while performing the in-focus control based on a result of the focus detection by the focus detection unit. | 04-21-2011 |
20120287330 | IMAGE PICKUP APPARATUS HAVING IMPROVED CONTRAST AUTOFOCUS ACCURACY - An image pickup apparatus includes an image pickup device that includes a plurality of focus detection pixels, a phase difference detection type of a first focus detector, a contrast detection type of a second focus detector, and a controller. The controller is configured to allow the second focus detector to continue the focus detection when the shift amount detected by the first focus detector is larger than a threshold even when the second focus detector detects the lens position corresponding to the peak of the contrast value, and to move the image pickup lens to a lens position that provides a peak of a contrast value detected by the second focus detector when the shift amount is the threshold or smaller. | 11-15-2012 |
20130088636 | IMAGING LENS-EXCHANGEABLE IMAGE CAPTURING APPARATUS AND CONTROL METHOD THEREFOR - An imaging lens-exchangeable image capturing apparatus comprises: a detection unit arranged to detect a focus state; a setting unit arranged to cause a user to set correction information for correcting the focus state or correction information for correcting control of a focus position based on the focus state; an acquisition unit arranged to acquire first lens identification information for identifying an attached imaging lens; an input unit arranged to enable the user to input second lens identification information for identifying the attached imaging lens; a storage unit arranged to store, for each imaging lens, the correction information, the first lens identification information, and the second lens identification information in association with each other; and a focus adjustment unit arranged to adjust a focus based on the detection result of the focus state and the correction information. | 04-11-2013 |
20140205329 | IMAGE FORMING APPARATUS - A heating roller heats an inner surface of a toner integrating belt to heat a toner image carried on an intermediate transfer belt to a toner softening temperature or more to form a toner film. A cooler cools down the inner surface of the toner integrating belt to cool down the toner film under pressure. | 07-24-2014 |
20140301762 | IMAGE FORMING APPARATUS - A heating member has a multi-layered structure of n layers in total to which layer numbers are assigned sequentially from one on a heat source side to a surface in contact with a recording medium. A n | 10-09-2014 |
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 |
