The image sensing device adapted to compose an appropriate single picture from a plurality of pictures of different exposures obtained from the same subject, wherein the camera operation is controlled using as a reference the signal of one of said plurality of pictures of different exposures.

Image sensing device

An image sensing device comprises an image sensor for photoelectrically converting an image sensing light coming from an object into an image sensing signal and for storing signal charges and providing a readout signal. Control circuitry variably sets storage times of the image sensor and an image composer composes an image signal for one picture from a plurality of readout signals from the image sensor having different charge storage times.

Image sensing device with diverse storage times used in picture

A data recorder has a first recording mode in which a rotary head records, on a tape-shaped recording medium, main data related to main information by forming many parallel tracks in a first area of the medium which extends in the lengthwise direction of the medium; and a second recording mode in which the rotary head records on the medium only sub-code data which is other than the main data by repeatedly recording the sub-code data many times forming many parallel tracks in a second area which extends in the lengthwise direction of the medium and in parallel to the first area.

Data recording apparatus having sub-code recording function

The image sensing device is adapted to compose an appropriate single picture from a plurality of pictures of different exposures obtained from the same subject, wherein the camera operation is controlled using as a reference the signal of one of said plurality of pictures of different exposures.

Image sensing device with diverse storage fumes used in picture

A data recorder comprises a first rotary head and a second rotary head which traces a tape-shaped recording medium travelling at a given speed by following recording tracks formed by the first rotary head. When an error of data reproduced from any of the recording tracks by the second rotary head is detected while data is being recorded by the first rotary head, the first rotary head is caused to record, in another track, data which is identical with the data reproduced from the above stated track depending on the data error occurring state of the track.

Data recording apparatus with recorded data verifying means

An apparatus for recording and reproducing information signals on and from a recording medium is arranged to cancel out an instruction for recording an information signal if some information signal has already been recorded on the medium.

Recording and reproducing apparatus

An information signal recording and reproducing apparatus, including a recording arrangement for recording information signals, the recording arrangement including at least one rotary head obliquely tracing a tape-shaped recording medium, the information signals including four kinds of pilot signals for tracking control which have frequency components different from each other a manually operable arrangement for producing a command to change a recording operation of the recording arrangement, a mark signal supplying arrangement for intermittently supplying a mark signal to the recording arrangement for a predetermined period in response to the command produced by the manually operable arrangement, the mark signal mainly having a predetermined frequency component which is distinguishable from frequency components of the four kinds of pilot signals, a reproducing arrangement for reproducing signals recorded on the recording medium, the reproducing arrangement including at least one rotary head obliquely tracing the recording arrangement, a separation arrangement for separating the mark signal from signal reproduced by the reproducing arrangement, the separation arrangement including a band-pass filter through which the predetermined frequency component is passed, and a control arrangement for controlling a reproducing operation of the reproducing arrangement in response to the mark signal separated by the separation arrangement.

Information signal recording and reproducing apparatus with a mark

A multi-channel reproducing apparatus which is capable of reproducing a recorded information signal from each of a plurality of areas of a tape shaped record bearing medium extending in the longitudinal direction of the medium is arranged to reproduce the information signal by repetitively allowing the medium to travel at a high speed while changing the information signal reproducing area from one area over to another.

Multi-channel reproducing apparatus with searching for programs

A multi-channel information signal reproducing apparatus for reproducing information signals from a tape-shaped record bearing medium having a plurality of areas which respectively extend longitudinally in parallel with each other, wherein only the signal reproduced from one area, designated by a designating circuit out of the plurality of areas, is taken among the signals reproduced by a rotary head, which obliquely traces the tape-shaped record bearing medium, thus, reproducing the information signal, and, at the same time, the designating circuit is controlled based on the signal reproduced by the rotary head.

Multi-channel information signal reproducing apparatus for reproducing

An audio signal recording apparatus comprises a detector for detecting a silent part of an incoming audio signal within the audio signal corresponding to less than a threshold value and generating a detection signal, a circuit for generating a reference signal of a predetermined frequency, a modulator for modulating the incoming audio signal to produce a modulated audio signal, a circuit for superimposing the reference signal on the modulated audio signal in response to the detection signal to produce a recording signal, and a recording circuit for recording the recording signal on a record bearing medium.

Audio signal recording apparatus

An information signal recording and/or reproducing apparatus, of the kind for recording or reproducing information signals on or from a tape-shaped record bearing medium which has a plurality of areas extending in parallel with each other in the longitudinal direction of the medium, is arranged to record or reproduce a first information signal with a first rotary head which traces the medium in such a way as to traverse each of the plurality of areas while rotating through an angle of .theta. degrees, and to record or reproduce a second information signal with a second rotary head which traces the medium by rotating at a phase differing by of n.theta. degrees, wherein 'n' is an integer other than 0, from the rotation phase of the first rotary head.

Multi-channel recording and/or reproducing apparatus capable of

An image pickup apparatus which alternately performs 1/n-sec light storage and 1/m-sec light storage (m&gt;n), and outputs an image pickup signal obtained by mixing a 1/n-sec stored image and a 1/m-sec stored image. The apparatus has a circuit for separately controlling white balance of the 1/n-sec stored image portion and the 1/m-sec stored image portion.

Image pickup apparatus

A video signal recording and/or reproduction apparatus in which an analog video signal from the inlet is digitized to form video data, then the video data are stored in a memory means for a time, then the stored video data are read out from the memory means before they are recorded on a recording medium. When reproducing the recorded video data from the recording medium, the reproduced video data are stored in a memory means for a time, then the stored video data are read out from the memory means, then the analog video signal is restored from the read video data, and then the analog video signal is produced at the output of the apparatus. Further, by taking the synchronism of the write and read control signals of different frequency for either of the memory means of the recording and reproducing systems, it is made possible to assure accurate and reliable conversion between the analog and digital forms of the video signals when either in the record or in the reproduction mode.
