摘要： An imaging apparatus includes an imaging unit configured to photoelectrically convert light of an object image formed by an imaging optical system to generate a signal, a first detection unit configured to detect a focusing state of the imaging optical system based on the signal generated by the imaging unit, a sensor configured to generate a signal different from the signal generated by the imaging unit without using the imaging optical system, and a second detection unit configured to detect an in-focus position of the imaging optical system based on the signal generated by the sensor. The sensor is located such that an amount of overlap between a detection range of the first detection unit and a detection range of the second detection unit at a first object distance is equal to an amount of overlap between those at a second object distance that is close to an infinite distance side compared to the first object distance.

摘要： An image pickup apparatus which is capable of optimizing the responsiveness of linear changes in focus to operations of a ring member without sacrificing the operability of the ring member, while using a small-sized, low-cost ring member for manual operations. The rotating operation state of a focus ring 600 is detected by ring rotation sensors 603, 604. A camera microcomputer 116 causes a focus lens 105 to be moved and stopped in an optical axis direction thereof based on results of the detection by the ring rotation sensors 603, 604. The camera microcomputer 116 controls the responsiveness of linear changes in focus to the rotating operation state of the ring member detected by the ring rotation sensors 603, 604 in accordance with at least the depth of focus.

摘要： A lens-controlling device controls a first lens unit which moves for zooming and a second lens unit which moves for correcting the displacement of an image plane caused by zooming and for focusing. The lens-controlling device includes a memory which stores data for obtaining target-position information representing a target position to which the second lens unit is to be moved, the target position corresponding to a position to which the first lens unit is moved from a current position and a controller which generates the target-position information on the basis of the data and controls the movement of the second lens unit on the basis of position information of the first lens unit and the target-position information.

摘要： An optical apparatus is disclosed, which is capable of suppressing an image blur at the start of zooming. The optical apparatus comprises a memory storing data indicating the position of a second lens unit according to the position of a first lens unit, and a controller. The controller controls the drive width of the second lens unit at a third position with a first driving condition in a case where the drive of the first lens unit is started from a first position, and controls the drive width of the second lens unit at the third position with a second driving condition in a case where the drive of the first lens unit is started from a second position. The drive width of the second lens unit at the third position with the first driving condition is smaller than that with the second driving condition.

摘要： The image pickup apparatus includes an image production unit producing an image by using an output signal from an image pickup unit, a size detection unit detecting a size of a specific object in the image, a zoom control unit performing auto zoom control that automatically provides a specific zoom operation to make the size of the specific object equal or closer to a target value, and a focus control unit performing focus control of an image taking optical system based on a contrast evaluation value obtained from the image. The zoom control unit is configured to restrict the specific zoom operation in the auto zoom control until a determination is made that an in-focus state of the image taking optical system has been obtained by the focus control.
