Abstract
In an image transformation apparatus for performing image transformation process to a video signal. A sequential read address is transformed based on the function of which a first differential coefficient reduces monotonously in a manner approaching "0" from "1", and the video signal is read out from a storing means by this transformed read address, so as to add an image collapsing effect to the video signal.
Claims8
An image transformation apparatus for performing an image transformation process on an input video signal, comprising:
- storing means for storing said input video signal;
- read address generating means for generating a sequential read address (x, y);
- and
- transformation means for transforming said read address (x, y) into a transformed read address (X, Y) based on formulas:
- X=x
- Y=F(y+G(x)-G(x)
- indicated by a function F(y) having a first differential coefficient which reduces monotonously in a manner approaching "0" from "1" and a pattern function G(x) representing a collapsing shape, said transformed read address (X, Y) is supplied to said storing means as a read address signal, thereby providing an image collapsing effect to said input video signal.
