Abstract: In an electronic still camera of the kind having a detachable mounted photo-taking optical system, an image sensor which converts into an electrical video signal an object image formed by the photo-taking optical system, a recording circuit which records the video signal and an electronic viewfinder which displays an image represented by the video signal obtained by the image sensor when the camera is in a shootable state, a confirmation member is arranged to confirm a mounted or detached state of the photo-taking optical system, and a driving-suspending and displaying-off control circuit is arranged to suspend a driving action on the image sensor and to turn off the electronic viewfinder when the detachment of the photo-taking optical system from the camera body is confirmed by the confirming member.

Abstract: An object of the present invention is to provide a compact television camera having a circuit that prevents switching noises by that a transistor of a power supply circuit being switched on for a dc-dc converter only during a blanking period eliminates the need for a transformer and shielding box for the dc- dc converter circuit and a low-pass filter circuit, thereby allowing the camera body to be made smaller. The compact television camera circuit, comprises in combination, a synchronizing signal generator (1), a timing signal generator (2) for generating a timing signal from said synchronizing signal generator (1) output, a vertical driver (3) and a horizontal driver (4) for generating vertical and horizontal scanning signals using the timing signal, a CCD pick-up device (5), a low-pass filter (8) for eliminating the high-frequency components of a video signal (b) output of said CCD pick-up device (5), and an output amplifier (11) for feeding out the video output signal (a).

Abstract: A video camera has a body with a rear surface at which a battery unit is normally mounted, a remote control receiver has front and rear surfaces respectively mating with the rear and front surfaces of the camera body and battery unit, respectively, interengageable coupling devices at the front and rear surfaces of the remote control receiver and camera body and at the rear and front surfaces of the remote control receiver and battery unit, respectively, so that the battery unit can be mounted directly at the rear of the camera body or with the remote control receiver between the camera body and the battery unit.

Abstract: A video camera unit including an enclosure having at least one exterior channel disposed on each of two opposed exterior surfaces of the enclosure, each exterior channel receiving a mounting device, the exterior channels extending substantially the length of the enclosure in a longitudinal direction of the enclosure, the enclosure further having an interior channel extending longitudinally along each of two opposed interior surfaces of the enclosure, a mounting plate, a video camera disposed on the mounting plate, the mounting plate being slidable into the interior channels for inserting and removing the video camera into and from the enclosure, the mounting plate having electrical connections thereon for receiving electrical power for the video camera, and a front door on the enclosure which can be opened to gain access to the video camera in the enclosure, the front door having a light transmissive member therein for allowing the video camera to monitor the environment outside the enclosure.

Abstract: In an electronic still camera of the kind having a detachably mounted photo-taking optical system, an image sensor which converts into an electrical video signal an object image formed by the photo-taking optical system, a recording circuit which records the video signal and an electronic viewfinder which displays an image represented by the video signal obtained by the image sensor when the camera is in a shootable state, a confirmation member is arranged to confirm a mounted or detached state of the photo-taking optical system, and a driving-suspending and displaying-off control circuit is arranged to suspend a driving action on the image sensor and to turn off the electronic viewfinder when the detachment of the photo-taking optical system from the camera body is confirmed by the confirming member.

Abstract: A camera-integrated video recorder in which a camera portion and a recorder portion are disposed in a single casing is arranged in such a manner that a grip portion having a viewfinder and a control portion for controlling the recorder portion is rotatably and detachably fastened to the casing. The grip portion acts as a remote control device for remote-controlling the camera portion and the recorder portion when it has been detached from the casing. The casing has an image transmission circuit for transmitting monitor image information to the viewfinder in the grip portion.

Abstract: A recording apparatus is disclosed which comprises a recording head accessible to a variable recording position on a recording medium; a 7-segment display device to display the variable recording position accessed by the recording head; a detecting member for detecting operating conditions of the recording medium, for example, the presence of the recording medium and the inhibition from recording of the recording medium; and a control circuit for causing the display device to display information on a predetermined operating condition of the recording medium in lieu of the recording position accessed by the recording head when the predetermined operating condition is detected by the detecting means.

Abstract: A camcorder having a battery compartment below the lens optical axis includes optical lenses for receiving light from an object. A housing is provided for housing the optical lenses. A battery load section capable of mounting a battery for supplying power to the housing is disposed at a bottom of the housing. The battery load section is capable of supporting different kinds of batteries of different sizes.

Abstract: In a video camera having an image sensor for converting an object image into a video signal, a viewfinder for visualizing the object image and a power source, waste of electric energy is prevented by controlling the supply of power to the viewfinder by detecting the access or non-access of the eye of a photographer to the viewfinder. Waste of electric energy is further prevented by controlling the power supply to the image sensor by detecting the state of the access of the eye to the viewfinder. In a case where the video camera is provided with a recorder for recording the video signal on a recording medium, waste of the recording medium is prevented by detecting the access or non-access of the eye to the viewfinder and by inhibiting a recording action of the recorder according to the result of detection, so that unintended meaningless shooting can be prevented.

Abstract: Switching circuits are disclosed which activate lighting in conjunction with the operation of a video recorder. The switching circuits employ signalling means such as relays, photo emitters or transistors to detect current flow in the video recorder motor circuit. Circuit elements receive the signal and activate a light. If the motor circuit is inoperative, the light remains off.
