PURPOSE:To reduce effects due to transmission errors or deterioration in the processing capacities of devices set at both transmission and reception sides and at the same time to improve the operability with a communication equipment for drawn images, by painting a closed area in response to the shift of a drawing pen and performing transmission over circuits for each sampling. CONSTITUTION:An image is drawn manually on a drawing pad 2 by a drawing pen and image signals are applied to a MPU 45 and stored in the R, G and B memories 41-43 in the form of image data. These image data are displayed on a color monitor TV 3. The image data processed by the MPU 45 are multiplexed 47 with input voice data given from a telephone set 1 via a MO DEM 46 and then sent to a subscriber line 48. When a pen-down action is given to an area enclosed by a closed curve of an image drawn manually by means of a control switch, a prescribed area is painted out centering on a point on the corresponding displayed image. Then it is checked whether the area to be painted out has a boundary or not in case the color of a sampled point is equal to the color of the memory or a designated color. Then the outside of the checked boundary is masked. |
