Claim 13:
14. 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 driving amount for driving the detector to perform the alignment between the selected shot region and the mold in accordance with a target position, held in a storage, to which the detector is moved 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 target position, 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 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 and the mold; and
updating the correction value held in the storage, and to be used during alignment of a subsequent shot region, based on the output of the detector at a time of performing the alignment for the selected shot region.
