  • Patent number: 10951876
    Abstract: The present invention is for more optimally performing recording and reproduction of stereoscopic video. In the present invention, parallax information is utilized to store, in a recording medium, stereoscopic video including left-eye images and right-eye images. Particularly, for video content that contains stereoscopic images, information is obtained regarding the amount of variation in parallactic angle having a given or larger value, a variation time that the variation in parallactic angle takes, and the number of times that the variation in parallactic angle occurs. An evaluation value is calculated that corresponds to the degree of eye fatigue on the basis of the amount of variation, the variation time, and the number of times of the variation. According to the present invention, the video content is encoded in such a manner that the evaluation value is within a given range, and then recorded in the recording medium.

  • Patent number: 5598273
    Abstract: In a magnetic recording control device, a plurality of test signals of different frequencies are recorded on and reproduced from a magnetic recording medium, and the reproduction levels of the test signals are detected. From the detection results, the frequency characteristics and electro-magnetic conversion characteristics of the magnetic recording medium are judged. A frequency correction in accordance with the judged frequency characteristics, and a record level correction in accordance with the judged electro-magnetic conversion characteristics are conducted on a video signal to be recorded.
