摘要： PURPOSE: To make it possible to store/print out required data during the printing of video data by starting the output of video data stored after the end of prescribed count operation of a counting means and printing out newly stored video data. CONSTITUTION: When a system control part 101 detects the execution of print- out operation, the output of stored video data to a recording part 108 is stopped and white picture data are outputted. Then the control part 101 instructs a counter 109 to start count operation. Thereby the counter 109 starts count operation and stores video data for one picture out of video data inputted to a video input part 104 in a video memory 105 for one picture. After the completion of the storage, the control part 101 reads out newly stored picture data and a picture processing part 107 executes prescribed processing for the read picture data. When the counter 109 ends the counting operation, the output of white data to the recording part 108 is stopped and video data are outputted from a processing part 107. Thereby the recording part 108 prints out new video data continuously to the white data.

摘要： PROBLEM TO BE SOLVED: To regenerate a touch as if an actual object is touched by providing an inflow-exhaust means of fluid for a fluid receiving part and a drive controlling means for controlling the inflow-exhaust means according to the separately inputted touch information. SOLUTION: A drive controlling section 104 judges the symbol of volume V3 concerning individual air bags and operates either of a switch valve 903 or switch valve 904 according to the result of the judgment. When the volume V3 is positive, the drive controlling section 104 controls the switch value 903 to infuse a medium in the air bag by the volume V3. The air bag 801 is used to regenerate the pressure applied to the whole hand of an operator and the air bag 802 is mainly used to regenerate partial fine pressure feeling on the respective positions of the palm or the respective fingers.

摘要： PROBLEM TO BE SOLVED: To apply higher image quality coding to a specific image area than other areas in the image coding. SOLUTION: An image identification separate section 1041 of an image CODEC 104 divides a received image into two image areas, the resolution of the image area not requiring high image quality is converted into low resolution by a resolution conversion section 1042 to reduce the data quantity and the image in the image area to be subjected to high image quality coding is coded while keeping high resolution. Furthermore, timers (1) 1047, (2) 1048 count respectively the coded time interval of the high image quality area and the low image quality area to increase number of frames of the high image quality area more than that of the low image quality area thereby smoothing a motion represented by the high image quality area.

摘要： PURPOSE:To eliminate a button for setting a polling receiving function and to automatically switch the polling receiving operation and a normal transmitting/receiving operation without the setting operation of an operator while using only the button for starting the communication. CONSTITUTION:When the start button of an operation/input part 104 is depressed, a mode detection part 110 detects an operating mode. When the operating mode is a reception mode, a timer part 109 starts counting time, and a system control part 102 detects whether a CED signal or an NSF.CSI.DIS frame signal is transmitted from an opposite side facsimile equipment through a MODEM 107 within fixed time or not. When those signals are transmitted within the fixed time, the polling receiving operation is started but when they are not transmitted, the normal receiving operation is started.
