Reading apparatus, reading method, and medium

A reading method to be performed by a reading apparatus including a transparent plate and a reader, the method comprising:

• an image generating process of reading an object placed on the transparent plate with scanning by the reader so as to generate an image corresponding to a result of the reading;
• a mark reading process of reading at least one first mark arranged overlapping with an edge of a sheet for adjustment placed on the transparent plate with the reader together with a region outside the sheet for adjustment;
• an extracting process of extracting at least one edge point on the edge of the sheet for adjustment based on the at least one first mark;
• and
• a correcting process of correcting a deviation in the image corresponding to the result of the reading generated in the image generating process based on position information of the at least one edge point extracted in the extracting process.

A non-transitory and computer-readable medium storing a program to be executed by a controller of a reading apparatus including a transparent plate, a reader, and the controller, the program is configured to cause the controller to perform:

• an image generating process of reading an object placed on the transparent plate with scanning by the reader so as to generate an image corresponding to a result of the reading;
• a mark reading process of reading at least one first mark arranged overlapping with an edge of a sheet for adjustment placed on the transparent plate with the reader together with a region outside the sheet for adjustment;
• an extracting process of extracting at least one edge point on the edge of the sheet for adjustment based on the at least one first mark;
• and
• a correcting process of correcting a deviation in the image corresponding to the result of the reading generated in the image generating process based on position information of the at least one edge point extracted in the extracting process.
