Patent ID: 8625913

Claim:
An image processing apparatus comprising: a unit that generates, from an input image of an i-th (i=1, 2, . . . ) frame, an image of a low frequency component in the image of the i-th frame as a low frequency component image i; a unit that generates, from the image of the i-th frame, a high frequency component-emphasized image i which emphasizes a high frequency component in the image of the i-th frame; a unit that performs lossy compression processing for the low frequency component image i to generate a compressed image i and store the generated compressed image i in a memory; a unit that decodes a compressed image (i−1) stored in the memory to generate a decoded image (i−1); a unit that decodes the compressed image i to generate a decoded image i; a unit that generates a difference image between the decoded image i and the low frequency component image i; a generation unit that composites the low frequency component image i, the decoded image (i−1), and the difference image at a predetermined ratio to generate a composite image; and an output unit that outputs the high frequency component-emphasized image i and the composite image as subframe images of the i-th frame.
