(54)Image processing apparatus and image processing method


(57) Each frame image is acquired as an input image. An image obtained by emphasizing high frequency components in the input image is generated as a high frequency component emphasized image, a composite image is generated by compositing the input image and an input image of a previous frame before the input image, and an image including low frequency components in the composite image is generated as a low frequency component image. Then, the high frequency component emphasized image and low frequency component image are alternately output as images of sub-frames of the input image.
