Abstract

Изобретение снижает объем данных, подлежащих передаче, при передаче, с целью синтеза движущегося изображения, изображений множества идущих подряд кадров, не допуская при этом появления нерезкости и/или остаточного изображения. Базовый сервер (3) содержит средства (11) передачи опорного изображения, предназначенные для передачи в объединяющий сервер (4) в заранее определенные моменты времени данных изображения кадра, используемого в качестве основы, входящего в множество изображений идущих подряд кадров, последовательно получаемых посредством устройства (2) получения изображений; средства (12) вычисления выделенной области, предназначенные для выбора изображения, представляющего собой фон, из множества изображений идущих подряд кадров, последовательно получаемых посредством устройства (2) получения изображений; и для последовательного вычисления третьей области (43), окружающей как первую область (41), так и вторую область (42), для каждого из кадров, следующих за опорным кадром, выбранным из множества идущих подряд кадров, последовательно получаемых посредством устройства (2) получения изображений; при этом первая область (41) представляет собой область, в которой образовалось отличие между изображением каждого из кадров и фоновым изображением; а вторая область (42) представляет собой область, в которой образовалось отличие между изображением кадра, непосредственно предшествующего каждому из кадров, и фоновым изображением; и средства (13) передачи выделенного изображения, предназначенные для последовательного выделения данных изображения третьей области (43) из каждого из кадров и передачи выделенных таким образом данных изображения в объединяющий сервер (4). Объединяющий сервер (4) содержит средства (14) синтеза изображения, предназначенные для синтеза движущегося изображения на основании данных опорного изображения, переданных из базового сервера (3), и данных изображения третьей области (43), выделенных из каждого из кадров.
