Abstract

The present invention is directed to obtaining an object having an anisotropic reflection characteristic without using a lenticular lens. A print product including a print medium on which a repetitive structure of projected portions and recessed portions is formed out of image forming materials including a color material includes a first layer formed on surfaces of the projected portions out of a first color material among the image forming materials, and a second layer formed on the recessed portions out of a second color material different from the first color material, wherein the projected portions have a height to occlude part of the second layer when observed at an angle different from an angle formed by a normal to a surface of the print medium.

1 . A print product including a print medium on which a repetitive structure of projected portions and recessed portions is formed out of image forming materials including a color material, the print product comprising:
 a first layer formed on surfaces of the projected portions out of a first color material among the image forming materials; and   a second layer formed on the recessed portions out of a second color material different from the first color material,   wherein the projected portions have a height to occlude part of the second layer when observed at an angle different from an angle formed by a normal to a surface of the print medium.   
     
     
         2 . A print product comprising:
 a first layer formed in a layer form on a print medium out of a first color material; and   a second layer formed in a layer form on the print medium out of a second color material different from the first color material,   wherein the first layer and the second layer are alternately arranged on a plane of the print medium, and   wherein the first layer is formed at a distance in a normal direction of a print surface of the print medium, the distance being such that part of the second layer is occluded when the first layer is observed at an angle different from an angle formed by a normal to the print surface of the print medium.   
     
     
         3 . An image processing apparatus comprising:
 a first acquisition unit configured to obtain a first observation direction and first color information about an object in the first observation direction;   a second acquisition unit configured to obtain a second observation direction and second color information about the object in the second observation direction, the second color information being different from the first color information;   a third acquisition unit configured to obtain unevenness data expressing a repetitive structure of projected portions and recessed portions on a print medium; and   a determination unit configured to determine an amount of a color material to be formed in the recessed portions and an amount of a color material to be formed in the projected portions based on the unevenness data, the first color information, and the second color information.   
     
     
         4 . The image processing apparatus according to  claim 3 , wherein unevenness expressed by the unevenness data is a groove structure arranged in a line pattern. 
     
     
         5 . The image processing apparatus according to  claim 3  e-r-  4 , wherein the determination unit is configured to determine the amount of the color material to be formed in the projected portions as the amount of a clear color material or a white color material. 
     
     
         6 . The image processing apparatus according to  claim 3 , wherein the first acquisition unit or the second acquisition unit is configured to obtain the first color information and the second color information according to user instructions. 
     
     
         7 . The image processing apparatus according to  claim 3 , further comprising a vector operation unit configured to perform a vector operation on the first observation direction and the second observation direction,
 wherein the unevenness data acquisition unit is configured to obtain the unevenness data based on a result of the vector operation.   
     
     
         8 . A program for causing a computer to function as the units of the image processing apparatus according to  claim 3 . 
     
     
         9 . An image processing method comprising:
 obtaining a first observation direction and first color information about an object in the first observation direction;   obtaining a second observation direction and second color information about the object in the second observation direction, the second color information being different from the first color information;   obtaining unevenness data expressing a repetitive structure of projected portions and recessed portions on a print medium; and   determining an amount of a color material to be formed in the recessed portions and an amount of a color material to be formed in the projected portions based on the unevenness data, the first color information, and the second color information.
