    • An object of the invention is to provide an image display device and a control method thereof which can reduce an image retrieving time and suppress an amount of data to be transmitted for retrieval.An image display device (4) is connected via communication lines to an NW cameral (1) for delivering picked-up images and a recorder (3) for storing the delivered images and displays the delivered images on an image display portion (43). The image display device (4) includes a data communication portion (41) for receiving image data from the NW camera 1, an image display control portion (42) for decoding the image data thus received and subjecting the decoded data to an image processing to thereby output to the image display portion (43), a thumbnail managing portion (44) for determining whether or not the received image data satisfies a predetermined condition as a subject to be displayed as a thumbnail, and a thumbnail storage portion (45) for storing only image data which is determined to satisfy the condition by the thumbnail managing portion (44).
    • 本发明的目的是提供一种图像显示装置及其控制方法,其可以减少图像检索时间并抑制要发送的数据量用于检索。 图像显示装置(4)经由通信线路连接到用于传送拾取图像的NW摄像机(1)和用于存储所传送的图像的记录器(3),并将所传送的图像显示在图像显示部分(43)上。 图像显示装置(4)包括用于从NW摄像机1接收图像数据的数据通信部分(41),用于对如此接收的图像数据进行解码的图像显示控制部分(42),并对经解码的数据进行图像处理 从而输出到图像显示部分(43),缩略图管理部分(44),用于确定所接收的图像数据是否满足作为缩略图显示的对象的预定条件;以及缩略图存储部分(45),用于 仅存储由缩略图管理部分(44)确定为满足条件的图像数据。
