Abstract
In order to obtain feature images representing features of products from product images, in a product image processor (), a receiver () receives product images each representing one product in a group of products with a common composition; a calculator () calculates a degree of scattering of pixel values at each of the positions in the composition from a pixel value at each of the positions in each of the received product images; a generator () generates a filter with a degree of transmittance defined at each of positions in the composition on the basis of a degree of scattering calculated at each of the positions; and an applicator () applies the generated filter to each of the received product images, thereby obtaining feature images, each representing a feature of each of the products.
