Abstract: Embodiments of the present invention seek to improve motion detection accuracy. A moving region discriminator 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 detects a moving region enclosed by still regions, and converts that moving region into a still region. A moving region expander converts into moving regions, a specified number of pixels of still regions adjoining regions determined to be moving regions.

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.

Abstract: UN APARATO DE GRABACION QUE ESTA CONFIGURADO PARA RECIBIR LAS SEÑALES ANALOGICAS DE AUDIO Y DE VIDEO, DIGITIZA Y COMPRIME LAS MISMAS, Y GRABA LAS SEÑALES COMPRIMIDAS DE VIDEO Y DE AUDIO EN UN MEDIO DE GRABACION DIGITAL TAL COMO UN DISCO OPTICO. A MEDIDA QUE SE RECIBEN Y SE GRABAN LAS SEÑALES DE AUDIO Y DE VIDEO, SE ANALIZAN CIERTAS CARACTERISTICAS DE LOS SEGMENTOS DE TIEMPO DE LAS SEÑALES DE AUDIO, TALES COMO SI EL SEGMENTO DE TIEMPO CORRESPONDE A LA MUSICA INSTRUMENTAL, A LA MUSICA VOCAL O AL HABLA CONVERSACIONAL. SE GENERA, ENTONCES, UNA TABLA DE CONTENIDOS CORRESPONDIENTE AL ANALISIS DE LAS CARACTERISTICAS Y SE ALMACENA DE FORMA DIGITAL EN EL MEDIO DE ALMACENAMIENTO. COMO RESULTADO, EL AUDIO GRABADO SE CARACTERIZA A TRAVES DEL TIEMPO, POR EJEMPLO, CON UNA BASE DE PAGINA POR PAGINA. SE PROPORCIONA, POR TANTO, UN ALTO GRADO DE VERSATILIDAD EN EL PROCESO DE REPRODUCCION, TAL COMO LA HABILIDAD PARA SALTARSE LAS PORCIONES QUE TIENEN CIERTOS TIPOS DE AUDIO, O PARA DESPLAZARSE RAPIDAMENTE HACIALAS PORCIONES DESEADAS DE LOS PROGRAMAS GRABADOS DE AUDIO. LOS APARATOS DE REPRODUCCION PERMITEN QUE EL USUARIO REPRODUZCA DE FORMA SELECTIVA LOS SEGMENTOS GRABADOS DE VIDEO Y DE AUDIO.

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).
