IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD

摘要

In an image processing apparatus, interlaced image signals are noninterlaced at double speed for each frame and the double-speed noninterlaced image signals each redundantly having the same information as that of the interlaced image signals are generated twice. After a predetermined image processing, odd scanning lines are extracted from a one double-speed noninterlaced image signal out of the two double-speed noninterlaced image signals to generate the image signal of the odd scanning lines An even scanning line is extracted from the other double-speed noninterlaced image signal to generate the image signal of the even scanning lines, thereby providing one frame of the interlaced image signal.
