Abstract
A video processing apparatus prevents image quality degradation, while reducing motion by combining high-frequency and low-frequency image data at the immediately preceding sub-frame at a first composite ratio α, generating first-sub-frame image data. By combining low-frequency image data and high-frequency image data at a second composite ratio 1-α, image data is generated as second-sub-frame image data. Then, the second-sub-frame image data is output with their polarity inverted with respect to the first-sub-frame image data. The ratio α is gradually decreased frame by frame at a first frame group, and the ratio α is gradually increased frame by frame at a second frame group subsequent to the first frame group.
