摘要： A predictive coding device comprises sampling circuitry for sub-nyquist sampling a video signal, and predictive coding circuitry for receiving a sampling value from said sampling means and outputting an encoded code. The predictive coding circuitry includes an encoder for encoding a difference between the sampling value and a predicted value corresponding to the sampling value, and outputting the encoded code, and a predictor for generating the predicted value using only an array of pixels in a vertical direction of a screen with respect to a sampling value of a pixel to be encoded by the encoder.

摘要： An apparatus for reproducing signals from a multiplicity of parallel tracks in a recording medium by means of n number of rotary heads, n being an integer not less than 3. A transportation device for transporting the recording medium is controlled on the basis of two kinds of signal: namely, a tracking control signal for leading one of the n number of rotary heads to one of m number of tracks contained in consecutive n number of tracks, m being an integer not less than 2; and a track shift signal which is generated in accordance with the result of a determination as to whether the n number of rotary heads are tracing expected tracks and which enable the tracks under tracing to be shifted to obtain a predetermined relationship between the sequence of the n number of rotary heads and the sequence of the tracks traced by these rotary heads.

摘要： A method of improving the radiation resistant characteristic of a BF.sub.3 proportional counter, comprising a tube having electrodes provided thereon and BF.sub.3 gas filled therein, by subjecting the counter before use to any one of 10.sup.4 -2.times.10.sup.5 R gamma ray, 10.sup.4 -2.times.10.sup.5 R X-ray, or 10.sup.10 -10.sup.11 nvt thermal neutron with a direct current high voltage applied between the above stated electrodes. The counter thus adapted exhibits little deterioration even in the surroundings of strong gamma ray, X-ray, and thermal neutron flux, and can maintain a stable operation. In particular, since the upper limit of the radiation amount in the process of improving the radiation resistant characteristic is set at a low value, the remaining life of the BF.sub.3 proportional counter is not shortened unduely.

摘要： An image frame is segmented into a plurality of groups of blocks characterized by movements approximating each other. An image reader receives a source image frame and a destination image frame in image data including consecutive image frames and segments the frames into blocks. A corresponding point information generator computes matching to detect corresponding point information indicating correspondence between the source image frame and the destination image frame and generates a corresponding point information file which describes coordinates of corresponding points in the image frames. An affine parameter calculating unit calculates affine parameters indicating deformation and movement of a block occurring between the source image frame and the destination image frame, on the basis of the corresponding point information. A seed block growth unit examiners a block adjacent to a seed block serving as a starting point for area growth and repeats a determination as to whether the seed block should be combined with the adjacent block so as to segment an image frame into a group of background blocks characterized by movements approximating each other and the other groups of blocks.

摘要： A frequency control circuit including a control circuit for setting a set value, an adding circuit for adding the set value per unit time and effecting counting based on the adding result, and a signal output circuit for outputting an alternating signal of a cycle corresponding to the time necessary for the count result by the adding circuit to reach a target value. The control circuit sets the set value as a value which does not correspond to a submultiple of the target value, and the adding circuit starts the counting of a next cycle when the count result reaches the target value. The control circuit further sets an initial value of the counting of the next cycle in accordance with a value of a portion of the adding results, exceeding the target value when the count result reaches the target value.

摘要： An apparatus for correcting a time base of a video signal generates a clock which is phase-synchronized with a sync. signal of the video signal and has the same frequency. In a special reproducing mode, the apparatus switches an output level of a phase comparator, which phase-compares the sync. signal and the clock to a predetermined level, which is applied to a controlled oscillator and resets a frequency divider which frequency-divides the output of the controlled oscillator, in accordance with the sync. signal to produce the video signal which can be visually recognized even in the special reproducing mode. The apparatus samples and holds the output level of the phase comparator when the video signal drops out and resets the frequency divider which produces the clock by frequency-dividing the output of the controlled oscillator, when the dropout is recovered so that a video signal of high quality is produced immediately after the recovery of the dropout of the video signal.
