Abstract
A pattern inspection apparatus is provided, including a reading mechanism configured to read a print pattern including an overlapped pattern portion formed by overlapping a first-pattern and a second-pattern and a single pattern portion formed with only any one of the first-pattern and the second-pattern; and a controller configured to perform acquisition of density information of the print pattern based on a result of the reading and correction of density information of the overlapped pattern portion by using density information of the single pattern portion.
Claims18
A pattern inspection apparatus configured to inspect a print pattern printed on a medium by a printer, comprising:
- a reading mechanism configured to read the print pattern including an overlapped pattern portion in which a first-pattern and a second-pattern are overlapped and a single pattern portion in which one of the first-pattern and the second-pattern is formed without overlapping;
- and
- a controller configured to acquire density information of the print pattern based on a result of the reading performed by the reading mechanism and to correct density information of the overlapped pattern portion by using density information of the single pattern portion.
A pattern inspection method for inspecting a print pattern printed on a medium by a printer, comprising:
- reading, by a reading apparatus, the print pattern printed on the medium by the printer, the print pattern including an overlapped pattern portion in which a first-pattern and a second-pattern are overlapped and a single pattern portion in which one of the first-pattern and the second-pattern is formed without overlapping;
- acquiring density information of the print pattern based on a result of the reading;
- and
- correcting density information of the overlapped pattern portion by using density information of the single pattern portion.
A printer configured to perform printing on a medium, comprising:
- a print unit which is configured to print a print pattern on the medium;
- a read unit which is configured to read the print pattern printed on the medium;
- and
- a controller which is configured to control the print unit and the read unit to perform:
- printing of the print pattern including an overlapped pattern portion in which a first-pattern and a second-pattern are overlapped and a single pattern portion in which one of the first-pattern and the second-pattern is formed without overlapping, by controlling the print unit;
- acquisition of density information of the print pattern based on a result of the reading;
- and
- correction of density information of the overlapped pattern portion by using density information of the single pattern portion.
