Abstract
This invention is to easily generate a normal map at a low cost. Hence, image data representing the characteristic of the surface of paper is inputted using an image input device. The type of finish of the paper is determined. Filtering processing corresponding to the type of finish is performed for the image data. A normal map is generated from the image data on which the filtering processing is performed.
Claims8
An image processing apparatus comprising:
- an input unit, configured to input image data representing a characteristic of a surface of paper, the image data being obtained by reading the surface of the paper using an image input device;
- a determination unit, configured to determine a type of finish of the paper by analyzing the image data;
- a filtering processor unit, configured to perform filtering processing corresponding to the type of finish;
- and
- a map generating unit, configured to generate a normal map from the image data on which the filtering processing is performed.
A method of controlling an image processing apparatus, the method comprising:
- inputting image data representing a characteristic of a surface of paper, the image data being obtained by reading the surface of the paper using an image input device;
- determining a type of finish of the paper by analyzing the image data;
- performing filtering processing corresponding to the type of finish;
- and
