Claim 0:
1. A device for measuring two-dimensional flicker for two-dimensionally measuring flicker of a measurement target object, the device for measuring two-dimensional flicker comprising:
a plurality of two-dimensional sensors individually including a plurality of photoelectric conversion elements that are two-dimensionally arranged in a row direction and a column direction, the plurality of two-dimensional sensors having a partial readout function of reading out only a pixel value of some of photoelectric conversion elements included in partial readout regions that have been set, among the plurality of photoelectric conversion elements; and
a hardware processor that:
two-dimensionally sets a plurality of measurement regions on the measurement target object;
individually acquires each pixel in the plurality of measurement regions, by setting each of the plurality of partial readout regions of the plurality of two-dimensional sensors, in each of a plurality of partial imaging regions obtained by dividing an entire imaging region corresponding to the measurement target object into the plurality of partial imaging regions; and
individually obtains a flicker value of the plurality of measurement regions, based on each pixel value in the plurality of measurement regions,
wherein:
each of the plurality of two-dimensional sensors sequentially scans in the column direction to perform a collective readout operation of collectively reading out each pixel value of the plurality of photoelectric conversion elements arranged in the row direction, and
the hardware processor sets the plurality of partial imaging regions by dividing the entire imaging region into pieces of a number of the two-dimensional sensors with a division boundary line being parallel to the row direction.
