Abstract
An image processing apparatus is provided that comprises an input configured to receive an image and a Laplacian generator configured to generate, from the image, a Laplacian pyramid that represents the image as a series of frames that contain different frequency components of the image. The image processing apparatus also comprises a compressor configured to compress the Laplacian pyramid for writing to memory.
