Image processing apparatus and interpolation frame generating method

Image processing apparatus and interpolation frame generating method

An image processing apparatus includes a frame memory (102), a motion vector detector (103), a screen edge detector (104) and an interpolation frame generator (106). The frame memory (102) frame-delays an input signal and outputs the input signal as a delayed input signal. The motion vector detector...

description An image processing apparatus includes a frame memory (102), a motion vector detector (103), a screen edge detector (104) and an interpolation frame generator (106). The frame memory (102) frame-delays an input signal and outputs the input signal as a delayed input signal. The motion vector detector (103) detects a motion vector between frames based on the input signal and the delayed input signal. The screen edge detector (104) detects a pixel corresponding to a screen edge in the input signal. The interpolation frame generator (106) generates an interpolation frame from the input signal and delayed input signal based on the motion vector and the pixel corresponding to the screen edge. The interpolation frame generator (106) generates the interpolation frame using the pixel corresponding to the screen edge or the pixel inside relative to the pixel corresponding to the screen edge when the motion vector points a pixel outside relative to the pixel corresponding to the screen edge.
