1. A blur correction device comprising:
a processor; and
a memory that is built into or coupled to the processor,
wherein the processor is configured to:
acquire an amount of blur correction used to correct blurring of an image obtained by imaging of an imaging element, during exposure for one frame in the imaging element,
correct the blurring by performing image processing, based on a most recently acquired amount of blur correction, on an unfinished image that is the image less than one frame that is being read from the imaging element, and
in a case in which a first reading period, in which the imaging element reads the image of a previous frame of previous and subsequent frames which are adjacent, does not overlap with a second reading period, in which the imaging element reads the image of the subsequent frame, correct the blurring by performing the image processing based on the amount of blur correction acquired during exposure between the first reading period and the second reading period, on the unfinished image of the subsequent frame.
