  • Patent number: 11706529
    Abstract: A blur correction device includes a processor and a memory that is built into or coupled to the processor. 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, and 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. In a case in which a first reading period does not overlap with a second reading period, the processor corrects 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.
