Abstract: An automatic focus adjusting device in which a distance measuring area is set from a plurality of distance measuring areas including a first distance measuring area and a second distance measuring area which differs in size from the first distance measuring area. A state of focus is discriminated in a distance measuring area before a focus adjusting operation is started by driving an optical element for focus adjustment when the optical element is in an in-focus state, and on the basis of the discrimination, a distance measuring area to be used after the focus adjusting operation is started is selected from the first distance area and the second distance area.

Abstract: The case of an image sensing apparatus such as a video camera is simplified by reducing the number of parts provided on the surface of the apparatus without eliminating a remote-control function. The video camera is formed to have an opening for introducing sensed light from a subject and first remote-control signal light which remotely controls the video camera into the interior of the camera case, and for projecting second remote-control signal light, by which the video camera remotely controls an external apparatus, to the exterior of the camera. After the first remote-control signal light is introduced into the interior of the camera case via the opening, the light is received by a remote-control light-receiving element and the second remote-control signal light is projected to the exterior of the camera case via the opening.

Abstract: A lens control device is arranged such that, in deciding a direction in which a focus lens is to be driven on the basis of the amount of change caused to take place in the level of a video signal by causing the focus lens to vibrate at a predetermined amplitude, the amplitude of the vibration of the focus lens is controlled according to the state of an AGC circuit.

Abstract: 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.

Abstract: An image pickup apparatus is provided with a pixel shifting device for shifting the incident light entering the image pickup device thereby substantially improving the resolution, and an image memory, and adapted to prevent deterioration of the resolution in case of reading a partial image from the image memory, by increasing the resolution using the pixel shifting device.

Abstract: There is disclosed a video camera which has a normal moving image sensing mode, and a still image sensing mode for sensing an image on a negative film set in a film adapter attached as a still image. An optical image of a subject is photoelectrically converted into an image signal, and whether or not the subject is a negative film is detected on the basis of a predetermined signal component in the image signal. If it is detected that the subject is the negative film, the still image sensing mode starts while setting signal processing in a negative/positive conversion mode and setting the focal length of the lens system at the wide-angle position.

Abstract: 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.
