The camera main body includes a control section which communicates with an interchangeable lens, and controls focus adjustment of the interchangeable lens by a hill-climbing AF system. A judgment section judges a characteristic of the interchangeable lens on the basis of communication between the interchangeable lens and the control section. The interchangeable lens includes a focus lens for performing focus adjustment. A focus lens drive section drives the focus lens. A lens control section communicates with the control section, and controls the focus lens drive section to perform focus adjustment. The control section changes a previously determined drive enabled range of the focus lens on the basis of a judgment result of the judgment section to perform focus adjustment of the interchangeable lens. | 10-30-2008 |
20100086293 | Focus detecting apparatus and an imaging apparatus - Disclosed is a focus detecting apparatus detecting an image offset of an optical system. The apparatus comprises a micro lens array arranged with a plurality of micro lenses, a photo-detector having a plurality of detecting elements provided so as to correspond to each of the plurality of micro lenses and receiving an optical beam from the optical system via the micro lenses, and a calculator that selects a pair of detecting elements from the plurality of detecting elements in accordance with a plurality of aperture values of the optical system and calculates an image offset of the optical system based on outputs from the pair of detecting elements. The pair of detecting elements receive respectively a pair of optical beams passing through different areas of the optical system. | 04-08-2010 |
20100098396 | IMAGE SENSING APPARATUS, CONTROL METHOD, AND USER INTERFACE DISPLAY APPARATUS - An image sensing apparatus on which a plurality of lens units are interchangeably mountable includes a system controller configured to acquired information specific to a mounted lens unit from the mounted lens unit, a detection unit configured to detect a focus shift amount of the mounted lens unit, a display circuit configured to display the specific information acquired by the system controller in association with a focus correction value for correcting the focus shift amount detected by the detection unit, an operation switch configured to be operated by a user, and a setting unit that sets the focus correction value according to an operation on the operation switch. | 04-22-2010 |
20100195997 | IMAGE PICKUP APPARATUS AND IMAGE PICKUP SYSTEM - A camera apparatus and a camera system of the present invention are configured so that a lens unit is attachable/detachable. The lens unit contains at least a lens and an iris, and contains a memory storing setting information required for operating the lens and the iris. When a camera microcomputer checks detection information stored in a memory in a sub-microcomputer at a time of start-up of the camera apparatus, and first detection information is stored in the memory, the setting information is acquired from the lens unit. When second detection information is stored in the memory, the setting information is acquired from another memory in the camera apparatus. Due to this configuration, the time for shifting the switch-on to a photographable state is shortened, and the ease of convenience can be enhanced. | 08-05-2010 |
20110164865 | AUTO FOCUS ADJUSTING APPARATUS AND CAMERA SYSTEM - An auto focus (AF) adjusting apparatus and a camera system of a lens replaceable camera are disclosed. AF is performed by correcting a location error of a focus lens due to a difference between a frequency band for performing AF detection and a frequency band for determining an improved location of an image surface of an imaging lens, and/or a target region for detecting a focal point. | 07-07-2011 |
20110200313 | IMAGE PICKUP APPARATUS AND IMAGE PICKUP SYSTEM - A camera apparatus and a camera system of the present invention are configured so that a lens unit is attachable/detachable. The lens unit contains at least a lens and an iris, and contains a memory storing setting information required for operating the lens and the iris. When a camera microcomputer checks detection information stored in a memory in a sub-microcomputer at a time of start-up of the camera apparatus, and first detection information is stored in the memory, the setting information is acquired from the lens unit. When second detection information is stored in the memory, the setting information is acquired from another memory in the camera apparatus. Due to this configuration, the time for shifting the switch-on to a photographable state is shortened, and the ease of convenience can be enhanced. | 08-18-2011 |
20110286733 | LENS-INTERCHANGEABLE CAMERA PERFORMING FOCUS CONTROL, LENS BARREL, AND PROGRAM - A lens-interchangeable camera includes a focus detector performing focus detection and a controller performing a drive control of a lens based on a defocus amount. The controller finishes focusing operation without driving the lens when the defocus amount is out a range of a first in-focus determination width, and performs the focusing operation when the defocus amount is out a range of the first in-focus determination width. The controller finishes the focusing operation without performing the focus detection again after completing the drive when the defocus amount is out a range of a second in-focus determination width, and performs the focus detection again after completing the drive when the defocus amount is out a range of the second in-focus determination width. The second in-focus determination width is set to be greater than the first in-focus determination width and be greater than or equal to a drive limit value. | 11-24-2011 |
