An image processing apparatus for extracting the specified objects has a background image extract unit for extracting a background; a first average background extract unit which extracts an image that includes a plurality of stationary and moving objects each having a speed not higher than a predetermined first speed and also the background; a second average background extract unit which extracts an image that includes the stationary and moving objects each having a speed not higher than a predetermined second speed and also the background; a first difference-calculation processing unit which calculates a difference between an output from the background image extract unit and an output from the first average background extract unit as a first speed image; a second difference-calculation processing unit which calculates a difference value between two outputs from the first and second average background extract units as a second speed image; and a third difference-calculation processing unit which calculates a difference value between an original image and either one of outputs from the first and second average background extract units as a third speed image.

Image processing apparatus

A multimedia data storing and transmitting method and a device using the method may improve flexibility and accuracy of reproduction of a multimedia data stream in a reception terminal, when a multimedia data storage device transmits the multimedia data stream. The multimedia data storing and transmitting method includes the steps of making a set of moving picture data, sound data, and multiplexed information of the moving picture data and the sound data into a packet, distinguishing a data packet of themoving picture data, the sound data, and the multiplexed information from a header packet of the moving picture data, the sound data, and the multiplexed information, storing the distinguished data packet and header packet, and transmitting the stored data packet following the stored header packet.

Multi media data storing and transmitting method and system using the same

A CPU, a main memory, a network interface section and a control section are connected to an internal bus. The control section is connected to a storage device to control read-out and write-in processes relative to the storage device. The network interface section receives an access request to the storage device transferred through a network and sends it to the control section through the CPU. The network interface section and the control section are connected to each other by an exclusive line. Data read out of the storage device and data to be written into it is transferred through the exclusive line.

Each of processor units 31-1-31-n comprises a CPU, memory, and interface function. A high-speed communications network 32 interconnects the processor units for inter-processor communications. Each of input/output units 33-1-33-n stores multimedia data and transmits the multimedia data through the network under the control of the corresponding processor unit. A processor control unit 34 controls the process of each of the processor units 31-1-31-n according to the process request received through the network. A switch 35 connects each of the input/output units 33-1-33-n to the network and exchanges data through the network. A communications line 36 transfers an instruction, etc. from the processor control unit 34 to each of the processor units 31-1-31-n.
