摘要： An image sensing apparatus operating with adaptive selection of a first tracing algorithm in which an object image is traced by moving a detecting area capable of being movably set on an image sensing plane in such a manner that the luminance level difference between the inside and the outside of that area becomes maximum and a second tracing algorithm in which the object image is traced by moving the position of the detecting area in such a manner that a point at which a contrast becomes maximum comes to coincide with a central portion of the detecting are depending on the state of the image sensing plane. The threshold values for changing over between the first tracing algorithm and the second tracing algorithm are made to have a hysteresis characteristic.

摘要： An apparatus for reproducing an information signal from a recording medium on which many tracks are formed, by periodically tracing the recording medium with a recording head. The position of the reproducing head relative to the recording medium is controlled on the basis of a tracking error signal which is obtained from the signals reproduced by the reproducing head. The track pitch is determined by a discrimination of a binary signal which is formed on the basis of a determination of whether the tracking signal is within a predetermined range.

摘要： The present invention is directed to a reproducing apparatus for reproducing a composite signal from a record bearing medium on which said composite signal is recorded, said composite signal being formed by frequency multiplexing a frequency-modulated luminance signal and a low-band converted carrier chrominance signal which is obtained by frequency-converting a carrier chrominance signal from a high frequency band to a low frequency band. The recording apparatus is constructed to separate the frequency-modulated luminance signal and the low-band converted carrier chrominance signal from the composite signal reproduced from said record bearing medium, to demodulate the frequency-modulated luminance signal to restore the luminance signal, to convert the low-band converted carrier chrominance signal into two kinds of color difference signals and to form R, G and B signals from the luminance signal and the two kinds of color-difference signals thus obtained. According to this construction, it is possible to form and output the R, G and B signals, without causing deterioration of signals.
