Abstract

En un area donde las imagenes cambias gradualmente, la deteccion exacta de un area de imagen estatica y una imagen en movimiento ha sido dificil. Un detector de movimiento comprende medios de deteccion de area de amplitud pequena (9) para medir las amplitudes en un area que incluye y adjunta pixeles predeterminados de la imagen, medios de extraccion de informacion de movimiento (10) para medir la variacion temporal de la imagen, medios de comparacion (2) para juzgar, a partir de la variacion medida si al menos el pixel predeterminado es un pixel de movimiento o no, medios para contar pixeles de imagenes de movimiento (3) y medios generadores de senales de movimiento para generar una senal de movimiento relacionada con el pixel predeterminado de acuerdo al resultado del ajuste. A mas pequena la amplitud medida, mayor la correccion de la ganancia de la variacion relacionada al menos con el pixel predeterminado, midiendo de este modo la variacion temporal de la imagen.
