The camera according to the present invention includes a reference optical system and a telescopic optical system. After photographing the subject using the reference optical system, a close-up of the subject is photographed using the telescopic optical system. As a consequence, when the subject is reproduced on a television screen, a sharp image can be obtained.

Camera for sequentially photographing a subject using a reference

A camera wherein a subject to be taken is pure-electronically still-photographed and recorded, and an image is reproduced by a television system and a printer. Resolution of the camera of this type is lower than that of the ordinary cameras. Accordingly, during the portrait photographing, it is necessary that the ratio of the face occupying in the taking background is made to be beyond a predetermined value. Then, when the taking distance is beyond a predetermined value, a warning is issued to call a photographer's attention to a close-in taking or automatically zoom-up.

A video recording/reproducing camera has a cover which covers control buttons associated with the reproduction operation to prevent an operator from touching the control buttons. A sensor switch detects whether or not the cover prevents the control buttons from being touched erroneously by the operator. When the sensor switch detects that the cover uncovers the control buttons to permit the control buttons to be touched by the operator, the operation of the video camera and the recording operation are disabled and only the reproduction mode is enabled. Therefore, the erroneous operations during the recording and reproduction modes are prevented.

A camera comprises an exposure frame for defining an exposure aperture in the camera body, an automatic film winding device incorporated in the camera body, and a light emitting element disposed at the exposure frame. The light emitting element is controlled to emit light to which a loaded film is exposed as the film is advanced by the automatic film winding device. The film provided by the camera, after development, shows a visible image of various line marks produced by the light emitting element which indicate that the film or a portion of frames on the film have been exposed under a certain mode of operation of the camera. The line mark is detected when picture images on the film are magnetically recorded on a magnetic sheet. The magnetic sheet is transferred to a reproducing apparatus in order to display the picture image on a TV screen in one of a variety of ways according to the line marks.

An arrangement for producing visual images recorded on a disk of film includes an imaging system having a solid-state image sensor, which can take a first position where it picks up the whole area of the disk of film, and a second position where it picks up a single frame of image recorded on the disk. A control unit, which is operative in response to manual instructions provided from a keyboard, causes the image sensor to be in its first position during an entire area display mode so that the entire area of the disk will be displayed on a display screen. In an individual frame display mode, the control unit causes the image sensor to be in the second position, in response to a desired frame being designated by the keyboard, so as to display the designated frame on the monitor screen. Video signals developed from the image sensor may be under image processings, such as negative-to-positive inversion, corrections of color balance, and image quality including gradation and tone, in response to information recorded on the disk of film.

A still picture to television signal conversion system for scanning a still picture to produce a video signal includes an image pickup device for scanning a still picture to form a video signal, which represents the still picture. A rotatable recording medium is caused by a drive unit to rotate. A recording unit is operatively connected to the image pickup device to record the video signal on the recording medium. A reproducing unit reads the video signal out of the recording medium for playback. A control circuit is constructed to enable the drive unit to rotate the recording medium at a first speed, cause the image pickup device to scan the still picture in synchronism with the rotation of the recording medium, and cause the recording unit to record the video signal on a predetermined recording unit of the recording medium. The control circuit is also constructed to cause the drive unit to rotate the recording medium at a second speed, and cause the reproducing unit to repeatedly reproduce the video signal which is stored in the recording unit and represents one still picture.
