Abstract: IMAGE PROCESSING APPARATUS, METHOD THEREOF AND MEDIUM The object of the present invention is to improve the motion detection accuracy. A moving region discriminator (63) of a motion detector circuit utilizes the field differential value and three frame differential values a through c to detect a moving region while also taking scene change, device mode information and line differential values into account. Frame differential values b and c are calculated utilizing the pixel positions on the lines above and below the line positioned with pixels for the calculated frame differential a. An isolation region eliminator (66) detects a moving region enclosed by still regions, and converts that moving region into a still region. A moving region expander (67) converts into moving regions, a specified number of pixels of still regions adjoining regions determined to be moving regions.

Abstract: A recording apparatus configured to receive analog video and audio signals, digitize and compress the same, and record the compressed audio and video signals on a digital recording medium such as an optical disk. As the audio and video signals are received and recorded, time segments of the audio signals are analyzed for certain features such as whether the time segment corresponds to instrumental music, vocal music or conversational speech. A table of contents is then generated corresponding to the feature analysis and digitally stored on the storage medium. As a result, the recorded audio is characterized over time, e.g., on a frame by frame basis. A high degree of versatility is thereby provided in the playback process, such as the ability to skip portions having certain audio types or to quickly scroll to desired portions of the recorded audio programs. Reproducing apparatuses enable the user to selectively reproduce segments of the recorded audio and video.

Abstract: A television receiver for receiving a first audio signal which is frequency modulated (FM) and which has a carrier with a first predetermined frequency difference from a carrier of a video signal. A second audio signal is pulse code modulated (PCM). The carrier has a second predetermined frequency difference from the carrier of the video signal. A tuner (2) is provided for receiving an RF signal and for generating an IF signal. A video detecting means (6) detects a video IF signal. An FM audio detecting means (13) detects the first audio signal. A PCM audio detecting means (16) detects the second audio signal. An audio IF detecting means (10) is connected between the tuner (21) and the FM audio detecting means (13) or PCM audio detecting means (16).

Abstract: A RECORDING APPARATUS CONFIGURED TO RECEIVE ANALOG VIDEO AND AUDIO SIGNALS, DIGITIZE AND COMPRESS THE SAME, AND RECORD THE COMPRESSED AUDIO AND VIDEO SIGNALS ON A DIGITAL RECORDING MEDIUM (18) SUCH AS AN OPTICAL DISK. AS THE AUDIO AND VIDEO SIGNALS ARE RECEIVED AND RECORDED, TIME SEGMENTS OF THE AUDIO SIGNALS ARE ANALYZED FOR CERTAIN FEATURES SUCH AS WHETHER THE TIME SEGMENT CORRESPONDS TO INSTRUMENTAL MUSIC, VOCAL MUSIC OR CONVERSATIONAL SPEECH. A TABLE OF CONTENTS IS THEN GENERATED CORRESPONDING TO THE FEATURE ANALYSIS AND DIGITALLY STORED ON THE STORAGE MEDIUM. AS A RESULT, THE RECORDED AUDIO IS CHARACTERIZED OVER TIME, E.G., ON A FRAME BY FRAME BASIS. A HIGH DEGREE OF VERSATILITY IS THEREBY PROVIDED IN THE PLAYBACK PROCESS, SUCH AS THE ABILITY TO SKIP PORTIONS HAVING CERTAIN AUDIO TYPES OR TO QUICKLY SCROLL TO DESIRED PORTIONS OF THE RECORDED AUDIO PROGRAMS. REPRODUCING APPARATUSES ENABLE THE USER TO SELECTIVELY REPRODUCE SEGMENTS OF THE RECORDED AUDIO AND VIDEO.(FIGURE 1)

Abstract: A method and an apparatus by which a panorama image is produced with a high degree of accuracy from an image signal are disclosed. An image signal produced by a CCD imaging element is recorded onto a video tape by way of a camera signal processing circuit, a recording signal processing circuit, a recording/reproduction amplifier and so forth. Meanwhile, a microcomputer calculates a motion vector of an image from the output of a motion vector detector to which the image signal from the CCD imaging element is inputted, and controls a video subcode processor so that motion vector information may be recorded onto the video tape. The motion vector information is reproduced from the video tape together with the image signal, and a plurality of images are formed from the thus reproduced image signal and joined together in accordance with the motion vector information to produce a panorama image.
