Abstract
An image processing apparatus can perform highly efficient coding that generates less visible distortion. The image processing apparatus includes a pre-processing unit configured to reduce the data amount of an input image and output the image after reducing its data amount and a coding unit configured to receive an output from the pre-processing unit and output coded data. The pre-processing unit includes a region segmentation unit configured to divide a frame image into regions, a filter setting unit configured to set filter strength, an intermediate region setting unit configured to generate an intermediate filter region in accordance with the filter strength, and a filter processing unit configured to perform filter processing at the set filter strength. Filter regions and filter strength can be set in accordance with the code length.
