<p><P>PROBLEM TO BE SOLVED: To provide an image processing device, capable of frame interpolation into a high-speed panning moving image, using a circuit and a circuit scale substantially equivalent to the conventional device. <P>SOLUTION: The image processing device includes: a memory control circuit for receiving pixel data of a present frame successively in order of lines to store into a line memory, and for reading out pixel data of a past frame successively in order of lines from a frame memory to store into the line memory; and an interpolation frame generator circuit for receiving a motion vector of a reduced vertical direction component, having a vertical direction component reduced by a first moving amount M1, defined according to the vertical direction component of panning speed, and for generating pixel data of an interpolation frame, based on the present frame pixel data and the past frame pixel data associated by the motion vector. The memory control circuit moves timing to store the past frame image data into the line memory from standard timing when the first moving amount M1 is zero, by a second moving amount M2 corresponding to the first moving amount M1. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
