Abstract
An image forming apparatus includes an image forming section that forms a pattern image for detecting image-position displacement with respect to a lenticular lens sheet. The pattern image includes periodic images in each of which set images, each including two or more images of different shades and having a length equal to a lens pitch of the lenticular lens sheet, are arranged in a lens transverse direction of the lenticular lens sheet. The periodic images are arranged in a lens longitudinal direction of the lenticular lens sheet so as to be gradually shifted from one another in the lens transverse direction by a distance less than the lens pitch.
Claims11
An image forming apparatus comprising:
- an image forming section that forms a pattern image for detecting image-position displacement with respect to a lenticular lens sheet, wherein
- the pattern image includes periodic images in each of which set images, each including two or more images of different shades and having a length equal to a lens pitch of the lenticular lens sheet, are arranged in a lens transverse direction of the lenticular lens sheet, and
- the periodic images are arranged in a lens longitudinal direction of the lenticular lens sheet so as to be gradually shifted from one another in the lens transverse direction by a distance less than the lens pitch.
A method comprising:
- forming a pattern image on a lenticular lens sheet by using an image forming apparatus, the pattern image including periodic images in each of which set images, each including two or more images of different shades and having a length equal to a lens pitch of the lenticular lens sheet, are arranged in a lens transverse direction of the lenticular lens sheet, the periodic images being arranged in a lens longitudinal direction of the lenticular lens sheet so as to be gradually shifted from one another in the lens transverse direction by a distance less than the lens pitch, the pattern image including adjustment values associated with positions in the lens longitudinal direction;
- acquiring the adjustment values at multiple positions, in the lens transverse direction, of a linear pattern having the same intensity by viewing the lenticular lens sheet having the pattern image from the lens side;
- and
- inputting, to an input unit of the image forming apparatus, the thus-acquired adjustment values for adjusting the image forming apparatus.
A method comprising:
- forming a pattern image on a printing medium by using an image forming apparatus, the pattern image including periodic images in each of which set images, each including two or more images of different shades and having a length equal to a lens pitch of a lenticular lens sheet, are arranged in a lens transverse direction of the lenticular lens sheet, the periodic images being arranged in a lens longitudinal direction of the lenticular lens sheet so as to be gradually shifted from one another in the lens transverse direction by a distance less than the lens pitch, the pattern image including adjustment values associated with positions in the lens longitudinal direction;
- placing the lenticular lens sheet on the printing medium having the pattern image;
- acquiring the adjustment values at multiple positions, in the lens transverse direction, of a linear pattern having the same intensity by viewing the lenticular lens sheet having the pattern image from the lens side;
- and
- inputting, to an input unit of the image forming apparatus, the thus-acquired adjustment values for adjusting the image forming apparatus.
