摘要： PURPOSE:To send a document generated by a document generating function directly from a facsimile equipment by storing an inputted document and sending it as required. CONSTITUTION:A television telephone terminal set is connected to an opposite television telephone terminal set 3 via a digital line network 2. A coordinate data corresponding to a character written by coordinate input device 13 is supplied to a controller 33 sequentially, A stored picture data processed by the controller 30 is stored in a hard disk device 35. Moreover, an image scanner 37 scans document or the like, converts it into a picture data and gives the result to the controller 30. A facsimile equipment 38 sends a picture data corresponding to the facsimile picture to be supplied from the controller 30 and to be sent through an analog telephone line different from a telephone line network 2.

摘要： PURPOSE: To make it possible to drive display devices of different kinds by common image signals by including plural main circuits which generate main image information, plural substitution circuits which generate substitutive image information and plural selection circuit means which select and output either of the main image information and the substitutive image information. CONSTITUTION: The plural main circuits 420 generate the main image information and the plural substitution circuits 430 generate the substitutive image information in correspondence to the respective main circuits. The selection circuit means 400 select and output either of the main image information or the substitutive image information in accordance with the identification information of the display device 414 supplied from an identification information generating means. Namely, when the display device is a CRT display device, the main image information is supplied as an output. On the other hand, if the display device is a flat panel display device, the selection circuit column 440 supplies the substitutive image information outputted from a substitution register column 430 as information signals. As a result, the driving of the display devices of the separate kinds by the common image signals is made possible.

摘要： PURPOSE:To easily and quickly select a video to be displayed and a video to be transmitted by providing a mode selecting means for selecting plural combinations being different from each other of a video displayed on a main screen, a video displayed on a sub-screen and a video of a video signal transmitted to the opposite side video telephone set. CONSTITUTION:This video telephone set is provided with a mode selecting means for selecting plural combinations being different from each other of a video displayed on a main screen, a video displayed on a sub-screen and a video of a video signal transmitted to the opposite side video telephone set. That is, when a key (person mode selection key) 6A, a key (picture/writing mode selection key) 6B and a key (still picture mode key) 6C of a key pad 6 are depressed, switching circuits 15A-15D and a CODEC 7 are controlled by a microcomputer 4. In such a way, from the video displayed on the main screen M and the sub-screen S, respectively of a color CRT 1, and the CODEC 7, the video of a color video signal transmitted to the video telephone set of the opposite side is selected with a combination.

摘要： PURPOSE:To solve difficulty in seeing caused by the superimposition of video by composing the subject picture display device so that a mode to superimpose plotting information on a video signal and project the plotting information and the video signal on a monitor can be switched to a mode to project only the plotting information on the monitor. CONSTITUTION:When the plotting information is inputted by using a tablet 15 while a mode for projecting pictures and writings, etc., is selected, the plotting information is sent from a tablet input/output control circuit 21 to a CODEC 17. Further, the plotting information is mixed with the plotting information from the other party in a plotting information control circuit 32, written in a video RAM 26, superimposed on the video signal, and sent to a monitor 11. When a only a handwritten memorandum, etc., are to be projected separately from the pictures and writings as stated here, a blackboard key 16Z of a key board 16 is operated and turned on. Thereupon, a black screen signal from a black screen signal generating circuit 36 is sent to the monitor 11 instead of the video signal. Consequently, a display state having a background equivalent to a blackboard all in a black color is obtained, only the plotting information is plotted on the monitor 11, and display easy to see corresponding to the plotting contents can be obtained.

摘要： PURPOSE:To eliminate unnaturalness in color from a picture by storing color difference data at every plural dots. CONSTITUTION:A memory 7 which stores luminance data and changing quantities of color difference data as picture data, means 10 which reads out the picture data from the memory 7 at the timing of dot clocks, calculates color difference data from the changing quantities of color difference data read out from the memory 7, and finds red, green, and blue color data R, G, and B from the luminance data and calculated color difference data, and a displaying means 35 which makes color dot displays based on the color data R, G and B found by the means 10 are provided. Therefore unnaturalness in color in a displaying picture produced when the display is made based on mean values of the color difference data can be eliminated.

摘要： PURPOSE:To prevent deterioration of the reproducibility of a high-frequency component of a specific color by converting red, green, and blue color data into luminance and color difference data based on plural conversion formulae. CONSTITUTION:A converting means 5 which converts red, green, and blue color data into luminance and color difference data based on one of converting formulae designated by converting formula designating data and a memory 7 in which the luminance and color difference data converted by the means 5 or the compressed data of the data are written are provided. Moreover, a reversely converting means 10 which reads out the data in the memory 7 and converts the data into the original red, green, and blue color data and a displaying means 10 which makes displays based on the reproduced red, green, and blue color data are also provided. Since the red, green, and blue color data can be converted into luminance and color difference data based on the plural conversion formulae, the most suitable conversion formula can be selected on each picture to be displayed and the picture quality can be improved.

摘要： PURPOSE:To perform display of many gradations by outputting the outputs of flip-flops as gradation pulses. CONSTITUTION:A CPU 1 of a system section SY outputs the color codes (8-bit) corresponding to display dots to a display controller 3 and writes the same into a VRAM 4, from which the codes are successively read out at the timing of the dot clock from a timing signal generating circuit 5 and are outputted to a look up table 6. The table 6 converts the codes corresponding to the display dots to the data of R(red), G(green), B(blue). The display dots are converted to analog color signals by a DAC (digital/analog converter) 7 and the color images are displayed on a CRT display device 9. On the other hand, the color codes outputted from the table 6 to a gradation data forming circuit 8 are converted to the 2-bit display data indicating the R, G, B data (12 bits) as the gradations of a monochromatic display. The data is then outputted as the 8-bit display data VD0-7 to an interface circuit 10.

摘要： PURPOSE:To reduce communication expense required for a conference by performing the transmission/reception of picture information mutually via a communication line first, and performing the simultaneous transmission/reception of control information and voice information next. CONSTITUTION:The picture information is read out from a floppy disk by a picture control part 12 prior to the conference, and is transmitted to an opposite side electronic OHP conference device via a line control part 2. The opposite side electronic OHP conference device accumulates the picture information by writing the picture information on the floppy disk. Also, after the conference is started, the control information for pointing or page turning, etc., inputted from an input control part 4 is transmitted to the picture control part 12, and also, part of a transmission band area is allocated to the control information and is transmitted to the opposite side electronic OHP conference device via the line control part 2. Therefore, the simultaneous communication of the voice and the control information in performing the conference can be realized. In such a way, the conference with inexpensive communication expense can be realized.
