Abstract

La presente divulgación se refiere a un método y a un dispositivo para navegar videos, y pertenece al campo de la tecnología de computadoras; el método incluye: comparar un fotograma actual con un fotograma anterior previo al fotograma actual en un video para obtener información de bloque objetivo; determinar el fotograma actual como un fotograma clave si la información de bloque objetivo satisface una condición predeterminada; determinar un fotograma próximo al fotograma actual como el fotograma actual, y continuar realizando el paso de comparar el fotograma actual con el fotograma anterior previo al fotograma actual en el video para obtener la información de bloque hasta que se compara el último fotograma en el video; y reproducir al menos un fotograma clave determinado; el dispositivo incluye: un módulo de comparación de imágenes, un módulo de determinación de imágenes, un módulo de ejecución de operación y un módulo de reproducción de imágenes; la presente divulgación soluciona el problema de no poder navegar un video ya que no se puede extraer un fotograma clave desde una toma continua, y logra el efecto de mejorar la eficiencia de reproducción del video.
