PROBLEM TO BE SOLVED: To solve the problem being a hindrance in rationalization and common use with a general television chassis in a convergence output circuit in a CRT-type projection TV (henceforth, PTV) since it is a special circuit in a television area. SOLUTION: Video image positions on screens of red, green and blue are controlled locally or on the whole so as to overlap colors by installing a color overlap adjusting means controlling compression, enlargement and deformation of a picture by converting a pixel by a digital signal processing. Thus, PTV which does not require the convergence circuit that conventional PTV has is realized. COPYRIGHT: (C)2005,JPO&NCIPI
