Abstract: The present invention provides an image blur correction apparatus, comprising: a blur detection device which detects a vibration applied to an optical system and outputs a blur signal in accordance with the detected vibration; an image blur correcting device which performs image blur correction to cancel out an image blur that is produced by a vibration applied to the optical system, based on a blur signal output from the blur detection device; a determining device which determines whether or not a determining condition that a size of a correction amount indicating a size of an image blur correction according to the image blur correcting device at least exceeds a predetermined threshold value, is fulfilled; and a correction switching device which, when the determining device determines that the determining condition is fulfilled, switches a mode of image blur correction performed to a mode of a pan/tilt operation.

Abstract: The present invention provides an image deflection correction apparatus which can switch a mode of image deflection correction (stop the image deflection correction) if it is judged that a camera (optical system) is in a pan/tilt operation, in which the determination condition for pan judgment as to whether or not the panning operation is active or the determination condition for tilt judgment as to whether or not the tilting operation is active, which is not satisfied ahead, is loosened, so that the operation is appropriately reflected to the starting motion of image on a photographing screen when the pan/tilt operation is performed in an oblique direction.

Abstract: The present invention provides an image deflection correction apparatus that can securely detect that the pan/tilt operation is ended, and securely switch to a proper mode of image deflection correction.

Abstract: A focus evaluation value used for contrast-determination autofocus (AF) and a focus position at the time of determination of the focus evaluation value are enabled to be outputted to a peripheral device such as a personal computer. This enables an operator to readily obtain information on the focus evaluation value from the peripheral device in a case such as an AF malfunction and thereby referring to the information to elucidate the cause of the AF malfunction. Furthermore, for determination of correct focusing in a tracking adjustment of a shooting lens, the relative magnitude of the focus signal continuously obtained according to video signals of a camera is displayed as a graph on a monitor, and the size of the graph is changed according to a maximum focus signal value obtained. Therefore, the graph can be displayed in an appropriate size on the monitor irrespective of variances of the magnitude of the focus signal due to different objects of shooting.

Abstract: The lens apparatus diagnostic system, the diagnostic program, the record medium, the lens diagnostic system and the controller diagnostic system have the effects of, by connecting a personal computer to a TV lens and having a diagnosis of the TV lens performed by the personal computer performing communication with the TV lens, implementing the diagnosis of the TV lens with an inexpensive system without necessity of providing a dedicated substrate for self-diagnosis to the TV lens and also capable of the diagnosis of an ENG lens. The personal computer is connected to the lens by an RS232C interface, and a program of an FIND system preinstalled on the personal computer is started. The FIND system allows a diagnostic mode for performing the diagnosis of the lens, a personal computer control mode for controlling the lens and so on to be selected, and the diagnosis of the lens is performed by the personal computer by selecting the diagnostic mode.

Abstract: The object distance display apparatus displays object distances according to actually measured object distance data entered in advance, matched with focusing lens positions acquired from a television lens device, and enables, when the apparatus is connected to the television lens device, any data entry error to be readily identified by graphically displaying the object distance data entered in advance. Actually measured object distance data entered in advance, matched with focusing lens positions, can be graphically displayed on an LCD panel with a touch panel function of the apparatus. If any abnormal datum such as an input error is detected, it can be deleted by touching a delete switch.

Abstract: The locking apparatus of a vibration proof lens automatically unlocks a movable vibration proof correction lens (a vibration proof lens) when electric power is applied, and automatically locks the lens at power-down, thereby eliminating a lock operation of the user and improving safety at the time of conveyance. The vibration proof lens and the locking apparatus thereof are mounted in a vibration proof adapter mounted between a television camera body and a lens apparatus, or a lens apparatus body. A power supply detection device detects that a camera power supply or an external power supply is connected and power is applied to vibration proof circuits, and activates a driving system such as an actuator to release a lock mechanism. On the contrary, when detecting that power supply becomes OFF, the power supply detection device activates the lock mechanism through the driving system to lock the vibration proof lens.
