Image reading apparatus, control method thereof, and storage medium storing program

A method for an image reading apparatus configured to read a sheet being conveyed and including a reading device configured to read one side of the sheet in units of a line area orthogonal to a conveyance direction of the sheet, the method comprising:

• storing, into a memory, a read image of a first region of a leading edge side of the sheet in the conveyance direction, and a read image of a third region subsequent to a second region subsequent to the first region and of a trailing edge side of the sheet in the conveyance direction;
• and
• performing predetermined processing based on the read image of the first region and the read image of the third region stored in the memory,
• wherein a read image of the second region is not stored in the memory.
