1. A printing device for printing an image, comprising:
an affixing part configured to affix ink to a printing medium; and
a controller programmed to control ink volumes of each of a colored ink, a light-shielding ink having light-shielding properties, and a special glossy ink having special gloss that are respectively affixed to the printing medium from the affixing part;
the controller including
a field discriminating part programmed to discriminate an overlap field in image data based on which the image is formed, the overlap field being a field in which a light-shielding ink field and a special glossy ink field overlap with respect to each other, the light-shielding ink being affixed to the light-shielding ink field, the special glossy ink being affixed to the special glossy ink field, and
an ink volume controller programmed to control reducing, in the overlap field, the ink volume of the light-shielding ink to a first volume of the light-shielding ink that is smaller than a second ink volume of the light-shielding ink, the second ink volume being predetermined in accordance with the image data.
2. The printing device according to claim 1, wherein
the ink volume controller adjusts to zero the ink volume of light-shielding ink that is affixed to the printing medium from the affixing part in the overlap field.
3. The printing device according to claim 1, wherein
the controller also includes a selection part for allowing the user to select whether or not the ink volume of the light-shielding ink is to be reduced by the ink volume controller.
4. The printing device according to claim 1, wherein the special glossy ink is metallic ink.
5. The printing device according to claim 1, wherein the light-shielding ink is white ink.
6. The printing device according to claim 1, wherein the printing medium is a transparent printing medium that has light-transmissive properties.
7. A printing method in which a printing device prints an image onto a printing medium, the printing method further comprising:
discriminating an overlap field in image data based on which the image is formed, the overlap field being a field in which a light-shielding ink field and a special glossy ink field overlap with respect to each other, a light-shielding ink being affixed to the light-shielding ink field and a special glossy ink being affixed to the special glossy ink field in accordance with inputted image data in which the light-shielding ink field and the special glossy ink field are set; and
printing the image while controlling reducing, in the overlap field, the ink volume of the light-shielding ink that is to be affixed to the printing medium to a first volume of the light-shielding ink that is smaller than a second ink volume of the light-shielding ink, the second ink volume being predetermined in accordance with the image data.
8. A medium for recording a computer program for printing an image using a printing device, the medium being a computer-readable medium for causing the computer to execute a field discrimination function for discriminating an overlap field in image data based on which the image is formed, the overlap field being a field in which a light-shielding ink field and a special glossy ink field overlap with respect to each other, a light-shielding ink being affixed to the light-shielding ink field and a special glossy ink being affixed to the special glossy ink field in accordance with inputted image data in which the light-shielding ink field and the special glossy ink field are set; and
an ink volume control function for controlling reducing, in the overlap field, the ink volume of the light-shielding ink that is to be affixed to the printing medium to a first volume of the light-shielding ink that is smaller than a second ink volume of the light-shielding ink, the second ink volume being predetermined in accordance with the image data.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A BPS receiver comprising:
a sampling process unit which samples a signal summing a first RF signal and a second RF signal of different frequency bands with time gap;
a quantization process unit which generates a first stream signal and a second stream signal, a digital signal down-converted through respective time information in the signal summing the first RF signal and the second RF signal; and
