摘要： A conventional device adjusts the convergence angle of its imaging unit in a manner that the left-and-right face detection areas are at the same coordinates and thus forms a stereo image that will be placed on a display screen during display, but fails to place a subject at an intended stereoscopic position. A stereo image capturing device (1000) detects a face area from a right image, detects a disparity using the left-and-right face areas, and sets the imaging parameters (the subject distance, focal length, stereo base, and convergence angle) to adjust the detected disparity to a disparity enabling the subject to be placed at an intended placement position. This device forms a stereo image having an appropriate stereoscopic effect in which a target subject is placed at an intended stereoscopic position. The device uses only a limited target area for face detection and thus requires less calculation for face detection.

摘要： The present invention provides a video encoding device in which a capacity of a binary data storing unit is small, a size of the video encoding device is small, a video signal can be processed in real time, and reduction in quality of images generated from the eventually obtained data can be prevented. The video encoding device according to the present invention includes: a video encoding unit which encodes a video signal; a binarization unit which binarizes an encoded value obtained from the video encoding unit; and an entropy encoding unit which subjects entropy encoding to binary data obtained from the binarization unit. Here, the video encoding unit encodes the video signal based on a characteristic of the binarization performed by the binarization unit, so that an amount of binary data obtained from the binarization unit by binarizing the encoded value that is encoded based on the characteristic is less than an amount of binary data obtained by binarizing an encoded value that is encoded without being based on the characteristic.

摘要： A video recording apparatus provides a slow motion effect or a quick motion effect by digitally converting the frame-rate instead of by changing the playback speed of the film, and using few recording media without requiring any special device at playing. A picture encoding part encodes only valid frames by changing a rate-controlling method so that a predetermined playing frame-rate is obtained at a standard data-rate at playing. And a TS multiplexing part multiplexes by converting a frequency of a standard STC clock by only a ratio of valid frame-rate and playing frame-rate, and generating values for PCR, PTS, and DTS.

摘要： In a digital signal magnetic recording/reproducing apparatus, input digital signals of plural channels and a recording current control signal expressing recording current values corresponding to the respective digital signals are time-division mulitplexed and transmitted into a rotary cylinder, and the digital signals and recording current control signal are separated by a circuit built in the rotary cylinder. The recording current for each of the digital signals is controlled depending on the recording current control signal. By time-division multiplexing the input digital signals of plural channels and transmitting the multiplexed signal into the rotary cylinder, the number of channels of the rotary transformer can be reduced. Further, by transmitting the recording current control signal into the rotary cylinder, the recording current of the digitally transmitted signal can be adjusted.

摘要： A digital signal magnetic recording/reproducing apparatus modulates a digital signal with a carrier and performs recording/reproducing of the modulated signal. The carrier frequency is made equal to the clock frequency multiplied by a factor (N/M), where N and M are integers. The carrier and clock are reproduced using only one phase locked loop. When the carrier-modulated signal is recorded/reproduced using a magnetic recording medium, the phase of the modulated signal is shifted relative to the phase of the carrier. Shifting the clock phase before using the clock for decoding the demodulated signal prevents a degradation of error rate. By periodically inserting a clock phase reference signal in the recording signal, accuracy of adjustment of clock phase is improved.

摘要： A transcoder reducing processing amount when a coded stream to which at least intra prediction is applied is transcoded into a coded stream to which intra prediction and inter prediction are applied.
