Claim 10:
11. An imprint method of performing, on a plurality of shot regions of a substrate, an imprint process for transferring a pattern of a mold to an imprint material arranged on the substrate, the method comprising:
performing alignment between a shot region selected from the plurality of shot regions and the mold, based on an output of a detector that detects a first mark provided in the substrate and a second mark provided in the mold, by:
determining a second driving amount for driving the detector to perform the alignment between the selected shot region and the mold in accordance with a first driving amount, held in a storage, by which the detector is to be driven to fit the first mark and the second mark within a specific region of a field of view of the detector, and a correction value, obtained during alignment of a previous shot region and held in the storage, used to correct the first driving amount, wherein the correction value indicates a shift amount, at the time of the alignment, between a center position of the field of view of the detector and a representative position decided by the first mark and the second mark; and
controlling positioning of the detector based on the determined second driving amount to perform the alignment between the selected shot region and the mold;

performing the imprint process on the selected shot region while performing the alignment between the shot region selected from the plurality of shot regions of the substrate and the mold based; and
updating, based on the output of the detector at a time of performing the alignment for the selected shot region, the correction value held in the storage and to be used during alignment of a subsequent shot region.
