Abstract
A sheet identification device includes an acquisition portion and an asperity identification portion. The acquisition portion acquires an identification image (Im1). The identification image (Im1) is an image of an identification region (R1) of the surface (A1) of a sheet (Sh1) on which image formation or image reading is performed. The identification region (R1) is a region on which pattern light (P1) is projected of the surface (A1) of the sheet (Sh1). The asperity identification portion identifies asperity information on the asperities on the surface (A1) of the sheet (Sh1), based on the identification image (Im1).
Claims21
A sheet identification device comprising:
- an acquisition portion configured to acquire an identification image which is an image of an identification region on which pattern light is projected of a surface of a sheet on which image formation or image reading is performed;
- and
- an asperity identification portion configured to identify asperity information on asperities on the surface of the sheet, based on the identification image.
A sheet identification method comprising:
- acquiring an identification image which is an image of an identification region on which pattern light is projected of a surface of a sheet on which image formation or image reading is performed;
- and
- identifying asperity information on asperities on the surface of the sheet, based on the identification image.
A sheet identification device comprising:
- an acquisition portion configured to acquire an identification image which is an image of an identification region on which pattern light is projected of a surface of a sheet on which image formation or image reading is performed;
- and
- an asperity identification portion configured to identify asperity information on asperities on the surface of the sheet, based on an integrated image obtained by integrating the identification image when the identification region moves by a certain amount of movement within the surface of the sheet.
