  • Patent number: 4974092
    Abstract: An automatic focusing device for a camera includes a camera section in which an optical lens system having a variable focusing position and a driver for varying the focus of the lens system are built-in. A desired scene is picked up through the lens systems and converted into a video signal by raster scanning. A signal extracting section defines a plurality of sampling points which are arranged in a direction which intersects the scanning lines of the video signal. The signal extracting section receives the video signal and, when the raster scanning reaches any one of the sampling points, extracts and holds the video signal. A computing section is responsive to the held signal for determining a direction in which the focus of the lens system is to be varied. A control section controls the driver on the basis of the determined direction to vary the focus of the lens system in that direction.

  • Patent number: 4954884
    Abstract: An automatic white balance adjusting method in which color difference signals (E.sub.R -E.sub.Y) and (E.sub.B -E.sub.Y) are respectively integrated on the entire screen and the gains of red and blue signals are controlled such that the average integration values can coincide with predetermined reference levels respectively. In the method, in integrating the color difference signals (E.sub.R -E.sub.Y) and (E.sub.B -E.sub.Y), the integration of the color difference signal that includes a chromatic color is prohibited. Whether or not the color difference signal includes the chromatic color is checked by whether at least one of a plurality of color signals including a color signal (E.sub.R +E.sub.B -2E.sub.Y), obtained by addition of the above-mentioned color difference signals, exceeds its associated one of a plurality of threshold levels which are set correspondingly to the respective color signals.

  • Patent number: 4928179
    Abstract: A video camera includes a light receiving device to enable a remote control operation to be achieved and a tally lamp to indicate a state of operation of the camera to the operator. The light receiving device and the tally lamp are installed in a housing such that when travel members disposed in a lower portion of the housing travel on an annular rail arranged on the body of the camera, the light receiving device and the tally lamp are moved to change directions thereof with respect to the body. An operator causes light to enter the light receiving device from a desired direction so as to operate the camera and to recognize a state of the operation of the camera by visually checking the tally lamp.

  • Patent number: 4922330
    Abstract: An automatic white balance adjusting method is disclosed in which color difference signals (E.sub.R -E.sub.y) and (E.sub.B -E.sub.y) are respectively integrated over the entire screen and the gains of red and blue signals are controlled so that the respective integration average values of these two color difference signals can coincide with their respective predetermined reference levels. In the integration of the above color difference signals, integration of the color difference signals of chromatic colors is prohibited. In the automatic white balance adjusting method, in order to check whether the respective color difference signals are chromatic colors or not, the respective color difference signals are added together and subtracted from each other to thereby generate color signals (E.sub.R +E.sub.B -2E.sub.y) and (E.sub.R -E.sub.

  • Patent number: 4829388
    Abstract: A magnetic recording apparatus such as a still video recording or an electronic camera includes a circuit for detecting a video signal immediately previously recorded on a track of a video disk to detect whether or not dropout exists in the video signal. Upon the detection of dropout, the recorded track is erased and the identical video signal is re-recorded on the same track. While the track is erased and re-recorded upon, dust or other foreign matter causing the dropout will be naturally removed from a magnetic recording head or the video disk so that the re-recorded signal is dropout free.

  • Patent number: 4819093
    Abstract: A rotary magnetic recording-reproducing apparatus in an electronic camera system, wherein a subject is purely electronically still-photographed and recorded on a rotating magnetic disc, and the reproduction of an image is carried out by a television set or a printer. When the tracking operation is performed up to the final track and the recording track cannot be detected (an envelope cannot be detected), a warning is issued on the basis of this fact so that loading of an unrecorded disc can be detected. Furthermore, when a track having a number other than one of the numbers of reproducible tracks is to be reproduced, a warning is given so that an operator can be informed of the fact that an unreproducible track has been reached.

  • Patent number: 4647167
    Abstract: In a disk film projector, a desired frame of an image recorded on a rotary disk of film is selectively placed at a projecting position for reproducing a selected frame in the form of a visible image. The disk film is designed to be rotatably driven to the projecting position by either manual or electrical driving devices. The manual driving device is mechanically connected with the disk film driving shaft, while the electrical driving device is detached from the shaft unless the electrical driving device is in operation. In this manner, the electrical driving device does not act as a load when the manual driving device is used, so that manual operation of the projector will be facilitated.

  • Patent number: 4635101
    Abstract: An apparatus for converting a negative image on a negative recording medium to a positive image includes a first converter for converting a composite video signal into its luminance and color difference components. A first processor electronically inverts the luminance signal while a second processor electronically inverts the luminance and color difference components together resulting in second luminance and second color difference signals. The second luminance and second color difference signals are encoded to produce a second video signal which is a positive image having corrected brightness and white balance.
