METHOD OF TRANSMITTING AND RECEIVING HAND-WRITTEN IMAGE AND APPARATUS FOR COMMUNICATION IN WRITING

摘要

The XY axis of the touch panel 14 superimposed on the LCD 12 is read at 15 msec and the current dot position of the writing instrument 11 in the XY axis is set to 20 bits according to the resolution of the touch panel 14 (1024 x 1024) The dot position from the touch panel controller 18, the LCD controller 16, and the touch panel controller 18 is compared with the dot position of the previous dot by converting the dot position into the dot position (X-axis 10 bits, Y-axis 10 bits) When the two dot positions are not adjacent to each other, the present dot position is used as the start point of the drawing and the 20 bits which are the first bit string are outputted as it is. If it is judged that the two dot positions are adjacent to each other, And a communication controller 25 for communicating the data of the first or second bit string in accordance with a predetermined communication protocol, so as to draw the input pen To the other party in real time.
