Title: Transmission system for still picture
Inventor: WAKAMATSU KUNIO
IPC: H04N7/12
Filed: 1978-03-02
Abstract: PURPOSE: To avoid flicker on picture during the replacement of picture, by alternately reading out the video signal equivalent to one horizontal scanning period from two field memories in the transmission of video signal between transmission and reception.  
     CONSTITUTION: The video signal stored in an even and odd number of field memorises 7a and 7b (picture memory) of the transmission and reception unit is read out alternately for one horizontal scanning period based on the readout address designation register 9, is transmitted to the transmission path 13 via the data selector 8, parallel serial converter 11, and MODEM 12, and it is alternately written in an even and odd number memory of the receiver. Since the system like this is adopted, when the received picture is newly rewritten, the rewrite progresses simultaneously for the both even and odd fields. For example, an alphabet A is rewritten into B, then rewrite is made sequentially from the upper part of screen (state 40). Different from conventional methods, no flicker is caused on picture as conventional cases (state 50) and stable picture can be obtained during rewrite.

Filed: 1985-02-12
Abstract: PURPOSE:To permit an erasure straight line to indicate a drawn picture image to be erased at the time of erasing a character, etc., and to erase easily it in an area by setting a primary erasure area by means of an inputted erasure curve and expanding said area when the area is below the given width so as to obtain a real erasure area. CONSTITUTION:Data on a character, a graphic, etc., are inputted to a control part 2 from the digitizer 1 of a system. In a processing step A the erasure area is set based on the erasure curve inputted by an operator, and in a processing step B an image data point in the vicinity of the area is retrieved. In a processing step C if the image data point is present, its outer area is retrieved, and the image data points from the position where the image data point disappears through the preset erasure area are retrieved, thereby deciding the point on the outer-most line to be a critical point. A polygonal area available from connecting sequentially the critical point in a processing step D is set a new erasure area, and outputted to a screen image buffer 3. With the erasure specification of one or two straight lines the screen displayed on a CRT monitor 4 can be easily erased.
