A control apparatus for an image display system that includes a first optical system configured to form a first optical image of an object, a second optical system configured to form a second optical image of the object, a first driving unit configured to move a first imaging position of the first optical image and a second imaging position of the second optical image, a second driving unit configured to move the second imaging position, and an operation unit operable to adjust the second driving unit includes a memory storing instructions, and a processor configured to execute the instructions to acquire information regarding the first imaging position and the second imaging position, and cause a display unit to display the information in a case where the second driving unit moves the second imaging position in accordance with an operation on the operation unit.

Control apparatus, image pickup apparatus, and lens apparatus

A control apparatus includes a first acquiring unit configured to acquire a hyperfocal length of a lens apparatus that is attachable to, detachable from, and communicable with an image pickup apparatus, using information acquired by communication between the lens apparatus and the image pickup apparatus, and a second acquiring unit configured to acquire a position of a focus lens in the lens apparatus according to the hyperfocal length.

Control apparatus and method, and storage medium

At least one exemplary embodiment is directed to an exposure apparatus which includes a chamber, an evacuating device configured to evacuate the chamber, a sensor configured to measure at least any one of the position and the height of a substrate, and a cover for hermetically sealing at least part of the sensor.

Exposure apparatus

An imaging optical system for imaging a pattern of an object plane onto an image plane includes a first imaging optical system for imaging at a first imaging position, the first imaging optical system having a magnification &#x3b1; in a vacuum atmosphere, and a second imaging optical system for imaging at a second imaging position, the second imaging optical system having a magnification &#x3b2; in the vacuum atmosphere, wherein when an environment in which the imaging optical system is placed changes from the vacuum atmosphere to an air atmosphere or vise versa, a direction of the first imaging position that moves along an optical axis is opposite to a direction of the second imaging position that moves along the optical axis.
