An electronic still camera an image-forming optical system for forming an image of an object, image pick-up for converting the image into an electrical signal, a first electric motor, a second electric motor, blocking device for allowing and blocking the light forming the image from reaching the image pick-up, the blocking device being driven by the second motor and a rotary member rotated at a uniform speed by the first motor, the rotary member having plural areas in each of which areas one frame amount of the electrical signal corresponding to a still image of the formed image is to be recorded. The camera further comprises recording device for recording the one frame amount of electrical signal in one of the plural areas of the rotary member during rotation, the recording device being moved by the second motor in such manner as to enable the recording device to shift from one to another of the plural areas for recording.

Electronic still camera with recording disk and recording control

An electronic still camera comprises an image-forming optical system for forming an image of an object, image pick-up means for converting the image into an electrical signal, a first electric motor, a second electric motor, means for allowing and blocking the light forming the image from reaching the image pick-up means, the blocking means being driven by the second motor and a rotary member rotated at a uniform speed by the first motor, the rotary member having plural areas in each of which areas one frame amount of the electrical signal corresponding to a still image of the formed image is to be recorded. The camera further comprises means for recording the one frame amount of electrical signal in one of the plural areas of the rotary member during rotation, the recording means being moved by the second motor in such manner as to enable the recording means to shift from one to another of the plural areas for recording.

Multi-motor electronic still camera having recording disk, focal plane

An apparatus for recording information on a sheet-like recording medium having a surface provided with a plurality of recording tracks formed concentrically about the center of rotation and guard bands provided between the recording tracks comprises first driving means for rotating the recording medium coupled to the recording medium, a magnetic recording head contacting the surface of the recording medium, means for energizing the recording head for a predetermined time by a time-serial electrical signal expressing the information, and second driving means for shifting the recording head in a direction across the recording tracks relative to the recording medium. The second driving means is adapted to shift the recording head from on one of the guard bands onto one adjacent recording track before the energizing means energizes the recording head and to shift the recording head from on the one recording track onto another adjacent guard band after the recording head has been energized for the predetermined time.

Electronic still camera

An electronic still camera provided with an electronic view finder displaying an image corresponding to the image signal obtained from the solid imaging device under the selected exposure condition. The electronic view finder is adapted to display an image corresponding to the image signals obtained at the solid imaging device under the selected exposure conditions before the image signal is recorded by a recording device.

Electronic still camera provided with an electrical viewing system

A solid state image pick-up device in which a light-receiving portion of MOS diode structure for accumulating therein charges corresponding to the intensity of light is formed on a substrate includes discharging means for discharging the accumulated charges into the substrate, and control means for controlling the discharging means in accordance with the exposure time of the solid state image pick-up device.

Solid-state area imaging device having interline transfer CCD

An electro-optical display element for a multiplexing system has a first and a second electrode substrate opposed to each other and an electrically responsive optical member provided between the two electrode substrates. Each of the two electrode substrates has combinations of ten segments, which are, in order from above, first, second and third lateral segments juxtaposed, a longitudinal upper left segment, upper middle segment and upper right segment juxtaposed between the first segment and the second segment, and a longitudinal lower left segment, lower middle segment, lower right segment juxtaposed between the second and third segments and a point segment for displaying the decimal point. The first electrode substrate has a first, a second and a third signal terminal. The second electrode substrate has a first, a second and a third scanning terminal. The signal terminals and the scanning terminals are specifically connected.
