摘要： PURPOSE: To transfer a moving image to plural different dynamic image transfer destinations. CONSTITUTION: At the device for transferring the dynamic image to a main body, a local bus slave engine 202 transmits an image transmission start signal 210, a data transfer timing preparing part 208 is started, and various kinds of timing signals 211-213 are prepared. Thus, a dynamic image processor 113 and a DMA address generating part are operated, the dynamic image processor outputs plural pieces of dynamic image data 217 in a prescribed format, and the DMA address generating part generates a DMA address 216 while selecting any transfer destination corresponding to the prescribed format. While using this DMA address, a local bus master engine 210 transfers the dynamic image.

摘要： PURPOSE: To enable a user to use a device without the anxiety about his privacy by validating a function with only user's direct mechanical operation and giving such structure that the function invalidating operation is automatically performed after the end of work. CONSTITUTION: When starting the use, the user grasps a cover knob part 6 to slide a cover part 2 upward. When the cover part 2 is fully pulled up, an iron plate 5 is attracted to an electromagnet 4, and the cover part 2 is kept open. A picture input part 1 is validated by this operation, and the user can start photographing a picture. When he will terminate the use of the picture input device, he grasps the cover knob part 6 to pull down the cover part 2 or the operation of the electromagnet 4 is stopped based on the support signal from a host computer. Thus, the electromagnet 4 loses the attraction, and the cover part 2 falls downward by its own weight and is moved to the position to shield the picture input part 1. The direct mechanical force is required to open the cover, and the start of operation without user's knowledge doesn't occur.

摘要： PROBLEM TO BE SOLVED: To eliminate a periodic read and to prevent trouble occurrence by transmitting a value indicating the state of this device to a transmission destination in a period wherein no transfer is performed. SOLUTION: A return address 220 received by a local bud/slave interface is written in a return address register 207 and transfer data 213, transfer destination coordinate data 214, and data timing 215 are outputted to a transfer data buffer 204 and a moving picture data address generation part 206. The state of each part is reflected on a status register file 205 at any time. Then the moving picture data address generation part 206 selects transfer data 216 and a moving picture data address 218 and a local bus master interface 201 sends them out to a local bus 111. Then the output 217 of the status register file and the output of the return address register are selected and after data are sent out by a certain amount, the contents of the status register file are sent out to the return address.

摘要： PROBLEM TO BE SOLVED: To recognize which opposite party is talking among plural call opposite parties by obtaining the physical position of a partial video whose change quantity with a previous frame partial picture in respective video information is the largest on a video display part. SOLUTION: A reception part 72 separately receives video information of plural terminals and receives mixed sound information obtained by mixing sound information of the plural terminals. Sound output means 41 and 42 are arranged near video display means 21 and 22 corresponding to the plural terminals. Position information detection means 142, 143 and 144 obtain change quantity with the previous partial pictures in video information, obtain the physical positions of the partial video whose change quantity is the largest on the video display parts 21 and 22 and execute counting. A sound volume control means 612 sound volume-controls the decoding signals of mixed sound information based on output from the position information detection means so that sound from the sound output means 41 and 42 correspond to the videos from the corresponding video display means and transmits the signals to the sound output means 41 and 42.
