Abstract: In order that each of two recording channels utilized for a single color television signal may be used if necessary to provide a complete picture with only a loss of quality, digitally coded signal samples of the luminance signal and of the two chrominance signal components are equally distributed between the two channels, successive luminance component samples going alternately to the two channels, each pair made up of related samples of the two chrominance components going entirely to one channel or the other, with successive pairs going to different channels. With the usual input sequence, a simple transposition of the sample sequence in one channel can make the sequences of the various components in the two channels identical.

Abstract: A system for measuring figures projected onto a charge coupled device (CCD) sums the data from a preselected number of adjacent pixels in a particular pixel line. The sum signal is divided by a full pixel signal to provide a mean pixel signal. The mean pixel signal is multiplied by a dimension per pixel value to provide a dimension signal representative of the dimension being measured. The dimension signal is compared with a reference dimension to determine the acceptability of the figure being measured.

Abstract: Digitally encoded (DPCM) NTSC video is transmitted in a standard T3 data format and rate via a transmit interface module. The module is subjected to inputs comprising DPCM encoded NTSC video, horizontal sync and a video sampling clock at 3f.sub.sc, where f.sub.sc is the color subcarrier frequency. The sampling clock is used to write the DPCM encoded video and horizontal sync into a buffer. The buffer is read out via a read clock which is a submultiple of the 44736 MHz T3 rate. To assist in receiver decoding, the video data is supplemented with horizontal sync indicating code words, which designate the start of each horizontal scan line. On detection of a horizontal sync word read out of the buffer memory, the read clock is inhibited for the insertion of the horizontal sync indicating code words. The T3 frame is also supplemented with two digitized audio channels, stuff indicators and a stuff opportunity slot as well as parity, frame and multiframe indicators and an alarm channel.

Abstract: There are video and sound recording devices such as movie cameras or video cameras with an automatic focusing system of the type for setting a photographic lens to a position at which an object can be sharply focused in response to the signal which is representative of a distance from the camera to the object and obtained by measuring the time interval from the time when the ultrasonic waves are transmitted at a predetermined repetition frequency to the object to the time when the echo from the object is received. Such devices have a common defect that a microphone picks up impulse-like noise generated from an ultrasonic transducer especially at the start point of ultrasonic waves. To overcome this problem, the present invention provides an audible noise elimination or suppression means or a control circuit which operates in synchronism with the ultrasonic wave transmission so that an audio signal processing system attenuates the audio output signal.

Abstract: Apparatus is provided for automatically controlling or locking the iris aperture of a camera. The brightness level of a signal produced by the camera is detected and an automatic control circuit responds to this detected brightness level to energize an iris drive, thereby establishing the iris aperture. The actual size of that aperture is represented by an aperture signal. This aperture signal is used by a control signal generator to generate a control signal corresponding thereto. A selecting circuit is operable to select either an automatic control mode wherein the iris drive is energized by the detected brightness level of the signal produced by the camera, or an iris lock mode wherein the iris drive is energized to maintain the iris aperture at a fixed size irrespective of changes in that brightness level.

Abstract: A video printing apparatus for forming color separation films and a color film recording an image of a video signal of a desired frame is disclosed. The video signal is once recorded on a 1" video tape together with time codes denoting respective frames. The video signal of the extracted frame is processed by time error corrector, a noise reducer and a detail corrector and then the thus corrected video signal is converted into R, G, B signals which are then stored in frame memories. The color signals stored in the frame memories are successively read out and are supplied to an interpolator composed of a hard logic circuit to produce interpolated color signals composed of a great number of scanning lines. The interpolation can be effected by one of cubic convolution, bilinear and nearest neighbor methods in dependence upon a kind of the image to be interpolated. The interpolated color signals are supplied to an electronic color scanner for forming cyan, magenta, yellow and black color separation films.

Abstract: Time-expansion is provided to one-line segments of the luminance component of a color television signal, and time-compression is applied to one-line segments of the chrominance component, so that both components can be recorded on magnetic tape with optimum utilization of the bandwidth of recording channels utilized for both components. Time-compression and -expansion is provided by control of the independent write-in and read-out rates of charge coupled device stores. A commutation system is provided for applying the required clock rates in proper sequence to the various stores, and another commutation system is provided for stringing signal segments of television line lengths of the respective luminance and chrominance components, so that recording can be done in reel time in two channels on a magnetic tape.

Abstract: A method for recording color separation picture images and an outline image simultaneously for use in a picture reproducing machine such as a color scanner and a color facsimile, wherein a plurality of color separation picture signals and an outline signal are obtained by scanning an original picture photoelectrically, wherein the outline signal is stored in a memory together with the color separation picture signals, in parallel, and then the stored signals are read out of the memory, in series, and wherein an exposure scanning means is controlled by the readout signals, thereby recording color separation picture images and an outline image on a photosensitive material in the same time.

Abstract: An automatic kinescope bias (AKB) control system for a television receiver operates in response to an enabling timing signal for maintaining a desired level of kinescope blanking current. The timing signal is applied to a control input of the AKB system via a timing signal coupling path. The timing signal input to the AKB system is inhibited for a given time interval after the receiver is initially energized, to delay AKB action until the kinescope has reached a desired operating temperature. The timing signal is inhibited by means of a control network coupled to the timing signal path. The given time interval is determined by a time constant circuit which is associated with the control network and which is substantially insensitive to the amplitude, and duty cycle of the timing signal.

Abstract: Synchronizing signals in a PAL system are generated without the need for an n f.sub.H oscillator by generating a reference signal having 568 cycles per line, adding a half cycle per line and then substracting one cycle per field. Pre-synchronizing signals are generated from the processed reference signal and the pre-synchronizing signals are then phase shifted by an amount which varies linearly with respect to elapsed time during each field from a value of zero to a value of substantially 1/(2 f.sub.sc).
