Provided is an image pickup apparatus including a lens apparatus and a focus operating apparatus. The lens apparatus includes a focus lens unit, a focus driving unit for driving the focus lens unit, and a drive control unit controlling to drive the focus driving unit and having a autofocus function. The focus operating apparatus includes a manual focus (MF) operating unit for manual focus adjustment and an MF command unit for outputting a command value based on an operation amount of the MF operating unit. When the MF operating unit is in operation, the drive control unit controls the focus driving unit based on the command value from the MF command unit. When the MF operating unit is not in operation, the drive control unit controls the focus driving unit to perform autofocus adjustment.

Image pickup apparatus including focus operating apparatus and focus control method

An image pickup apparatus comprising: a lens apparatus having: an image pickup optical system including a focus lens unit and a zoom lens unit; a zoom state detector; and a controller; a camera apparatus having: a light receiving unit; and an image display unit; an AF frame operation unit; and a distance measuring unit installed with a parallax with respect to an optical axis of the image pickup optical system, in which the controller is configured to: select, from among measured distances obtained by the distance measuring unit, a measured distance obtained in an angle of field of the AF frame, based on a position of the zoom lens unit detected by the zoom state detector and a position of the AF frame set in the display; and perform the focusing by driving the focus lens unit based on the selected measured distance.

A drainage connector communicates between a drain outlet of a toilet drainage path connected to a toilet bowl and a connecting port of a drain conduit led into a room equipped with a toilet body. The drainage connector includes a casing formed with a flow inlet connected to the drain outlet and a flow outlet connected to the port, and piping disposed in the casing. The piping has an upstream piping having an upstream opening communicating with the flow inlet and forming a downward flow path when the drain outlet communicates with the port and a downstream piping connected to the upstream piping and having a downstream opening open to the casing in a lateral direction along an inner surface of the casing so that flush water flows out in the lateral direction. The downstream piping forms an upward flow path when the drain outlet communicates with the port.

The image pickup system is constituted by a lens apparatus including a focus lens and an image pickup apparatus performing image pickup through the lens apparatus. The system includes an operating part being operated to instruct a movement of the focus lens, a controller performing focus position control to move the focus lens to a position corresponding to an operation amount of the operating part, a ranging part detecting an object distance in each of plural ranging areas included in an image pickup region, and a determining part determining a distance range where the object distances detected in the plural ranging areas are distributed. The system further includes a changing part changing a relationship between the operation amount of the operating part and the position of the focus lens in the focus position control according to a determination result by the determining part.

In S, it is determined whether an instruction has been input to drive a wiper serving as an optional member. If a wiper driving instruction has been input, the process shifts to Sto perform wiper driving control. If no wiper driving instruction has been input, the process shifts to S. In S, it is determined whether the wiper is during driving. If the wiper is during driving, the process shifts to S. If the wiper is not during driving, the process shifts to S. In S, it is determined whether information of the capacity of current suppliable from a television camera () to a television lens () has been output. Also in S, the current capacity information is monitored. If no current capacity information has been output or the current capacity is small, the process shifts to Sto stop driving control of a focus lens and zoom lens.

An optical apparatus includes a detection unit for detecting a reference position, a detection unit for detecting a relative position, and a control unit for outputting a control signal for the optical apparatus after an operation speed of a moveable input member for drive-controlling the optical apparatus becomes equal to or slower than a predetermined speed.

Method and apparatus for controlling lens position

A drive control apparatus for a lens apparatus having a zoom lens movable between a telephoto end and a wide-angle end according to the present invention comprises a selecting member which selects a zoom position between the telephoto end and the wide-angle end, a controller which has a drive range limiting function of controlling drive of the zoom lens by using the selected zoom position as a drive end, and a drive range switch member which switches the drive range limiting function between an invalid state and a valid state. The controller drives the zoom lens to the drive end when the drive range limiting function is switched to the valid state.

In a lens device, when a lens is subjected to speed control and when initialization in which an absolute position of the lens is initialized after a power supply is turned on is completed, the lens is returned to a position before the lens is initialized.

Lens device and photographing apparatus including the same

An optical apparatus which can be focused on an object included at an arbitrary position in an image-taking area with simple operations, is disclosed. The optical apparatus according to the present invention comprises a focusing state calculating circuit which derives information indicating a focusing state of an optical system based on an output signal from an image-pickup area which corresponds to part of an image-pickup device, and a storage circuit which stores the position of the image-pickup area in the image-pickup device. The optical apparatus also comprises a setting system which moves the image-pickup area, stores the position of the image-pickup area in the storage circuit, and sets an image-pickup area which has been stored in the storage circuit as the image-pickup area in performing focus adjustment control.
