An image processing apparatus according to the present invention includes an image coding apparatus including a first encoding unit configured to be input with an image having a first resolution, and, on a block basis, perform prediction of a block subjected to coding based on coded pixels to code the image and generate first prediction information indicating a prediction method; a scaling unit configured to scale a first image output from the first coding unit based on a ratio of the first resolution to a second resolution larger than the first resolution, by using a filter determined by the first prediction information, to generate inter-layer pixel prediction reference data; and a second coding unit configured to be input with an image having the second resolution, and, on a block basis, perform prediction based on coded pixels or the inter-layer pixel prediction reference data to code the image.
