1. A vector calculation device comprising:
at least one processor; and
at least one memory holding a program that makes the processor function as:
an acquisition unit configured to acquire data including pixel information of a pixel in which a change in luminance occurs;
a generation unit configured to perform a predetermined process on the data acquired in a first time period from a start time to generate a frame;
a control unit configured to perform control such that the first time periods are overlapped partially for a plurality of the frames; and
a calculation unit configured to calculate a motion vector based on a frame group including the plurality of frames for which the start times of the predetermined process are within the first time period from the start time for the first frame in the group.
