摘要:
A video camera apparatus having a plurality of functions including a select switch through which a mode for executing one of various functions is selected, an execute switch through which a particular mode selected through the select switch is executed, and a controller which controls the display of a representation of the selected mode on the electronic viewfinder before the execute switch is operated. Thereafter, when the execute switch is operated, the mode is entered. The controller may include a selection cancelling device for cancelling a previously selected function.

An information communicating apparatus and method are featured in retrieving one or more device constituting a network which satisfies predetermined conditions (e.g., connector type and data transfer speed) and has a communication port not connected to another unit of device. The retrieved device is then graphically displayed on a display screen. Users can be informed of the device having a vacant port in a manner easy to understand, and add-on of new device to the network can be realized readily and efficiently.
摘要:
A selection apparatus including a display unit for indicating a plurality of displays on the same screen, a line-of-sight position detecting unit for detecting a line-of-sight position of an operator on the screen, and an input unit through which the operator inputs an instruction, the input unit operating without using a line of sight. The selection apparatus also includes a control unit. When the display unit displays all of the displays on the same screen in response to an instruction input through the input unit, and the line-of-sight position detecting unit detects the line-of-sight position on any of the displays, the control unit selects the display on which the line-of-sight position has been detected. The control unit differentiates a status of display of the selected display from those of the non-selected displays. The control unit then executes the contents of the selected display. Preferably, for example, a photographer may perform function selection by manipulating a switch while looking at a function menu displayed on the screen.

A lens control device comprising a variator lens group for zooming, a focusing lens group for compensating for a change introduced into the focused position as a result of a zooming operation by the variator lens group, a conversion lens group for changing a focusable shifting area of the variator lens group from a first area to a second area, a computing circuit for determining driving information for driving the focusing lens group during the shifting of the variator lens group, based on focused position data, according to object distance, of the focusing lens group relative to the position of the variator lens group, and a control circuit for shifting the variator lens group from the first area to the second area in response to the mounting of the conversion lens group and for controlling a computing operation of the computing circuit so that a focused position of the focusing lens group is determined when the variator lens group moves within the second area.
摘要:
A camera of the type having a lens drive motor for moving a focus lens, an image pick-up device for converting an optical image passed through the optical system including the focus lens into an image signal, a sampling circuit for sampling the high frequency component value of the image signal, and a control circuit for controlling the lens drive motor so as to maximize the high frequency component value. The camera has a high frequency component value memory for storing a history of the high frequency component value sampled by the sampling circuit. The control circuit controls the lens drive motor so as to maximize the high frequency component value after the focus adjustment, in accordance with the stored history of the high frequency component value.
摘要:
A photographing apparatus comprises a first lens group to variably change a magnification, a second lens group to perform a focus adjustment, a movement measuring sensor to measure a moving speed of the first lens group, a movement control circuit to move the second lens group at the moving speed according to a measurement value of the moving speed which is obtained from the movement measuring sensor and a speed change circuit to change the moving speed of the first lens group. The apparatus has a stop circuit for allowing the movement control circuit to stop the movement control of the second lens group according to the measurement value of the moving speed obtained from the movement measuring sensor when the moving speed derived from the movement measuring sensor is changed.
摘要:
An automatic focus adjusting device in a camera system includes a focus detecting circuit for a focusing state of an object image formed on an image plane by a photographic lens, a control circuit for producing a control signal on the basis of an output of the focus detecting circuit and for outputting the control signal to the photographic lens to control the same, and a characteristic detecting circuit for detecting a predetermined optical characteristic of the photographic lens. The control circuit is arranged to transmit the control signal to the photographic lens by defining as a parameter a change of the optical characteristic detected by the characteristic detecting circuit.
