Claims
- 1. A video display control system for displaying a video image on a screen of a video display unit comprising:
- (a) memory means for storing (i) first to Nth (N.gtoreq.2) animation pattern data, each representing an animation pattern including a predetermined number of pattern elements which can be displayed on the screen at different locations, each of said pattern elements corresponding to at least one of display elements on said screen, (ii) first to Nth display position data which specify data to be displayed on first to Nth display positions, respectively, each of which is a position on said screen, and (iii) first to Nth color data which are digital numbers, each of which represent colors for said first to Nth pattern data, respectively; and
- (b) display control means which comprises:
- (I) reading means for reading said first to Nth animation pattern data, said first to Nth display position data and said first to Nth color data from said memory means;
- (II) processing means for receiving said first to Nth animation pattern data, said first to Nth display position data and said first to Nth color data read from said memory means, for determining collisions between said animation pattern data and for effecting a logical operation between bits of said first to Nth color data which overlap to output said first to Nth color data corresponding to said animation pattern data which collides; and
- (III) operation effecting means for receiving said first to Nth color data outputted from said processing means and for producing, when said processing means outputs at least two color data among said first to Nth color data for a same display element on said screen, a new color data by effecting a logical operation which combines said digital numbers for each bit of said at least two color data for at least two animation patterns which partially overlap with each other on the screen, and to supply said new color data to said video display unit.
- 2. A system as in claim 1, wherein N.gtoreq.3.
- 3. A video display control system for displaying a video image on a screen of a video display unit comprising:
- (a) memory means for storing (i) first to Nth (N>3) animation pattern data, each representing an animation pattern including a predetermined number of pattern elements which can be active or inactive and can be displayed on the screen at different locations, each of said pattern elements corresponding to at least one of display elements on said screen, (ii) first to Nth display position data which specify data to be displayed on first to Nth display positions, respectively, each of which is a position on said screen, and (iii) first to Nth color data which are numbers each of which represent colors for said first to Nth animation pattern data, respectively; and
- (b) display control means which comprises:
- (I) reading means for reading said first to Nth animation pattern data, said first to Nth display position data and said first to Nth color data from said memory means;
- (II) processing means for receiving said first to Nth animation pattern data, said first to Nth display position data and said first to Nth color data read from said memory means, for determining collisions between said animation pattern data and for adding said numbers for color data corresponding to said animation pattern data from said collisions when a pattern element thereof is active, to output synthesized color data indicative of said added numbers; and
- (III) operation effecting means for receiving said first to Nth and synthesized color data outputted from said processing means and for producing, when said processing means outputs at least two color data among said first to Nth color data for a same display element on said screen, a new color data by effecting a logical operation which combines said digital numbers for each bit of said at least two color data for at least two animation patterns which partially overlap with each other on the screen, and to supply said new color data to said video display unit to produce an image for said video display unit based thereon.
