Abstract
PURPOSE:To attain high speed processing by setting a desired area on a screen at a zoom starting position and a zoom completing position and designating a zoom magnification. CONSTITUTION:An in-window zoom processing device is composed of a parallel serial converting circuit for one plane by a control part 5, first second shift registers 1-2 and first second multiplexers 3-4. In order to expand only the inside of a multiwindow, a shift register 2 for a sampling time of the same constitution as the first shift register 1 provided for the parallel serial conversion of respective planes is obtained. By the shift clock based on the zoom magnification, the parallel data of respective planes are converted, and then, the sampling data are shifted by the output of the shift register 2 and the desired in-window zoom is realized. Thus, without troubling the labor of an operator, a high speed processing can be executed.
