Two-dimensional flicker measurement device, two-dimensional flicker measurement system, two-dimensional flicker measurement method, and two-dimensional flicker measurement program

A two-dimensional flicker measurement system for measuring a flicker amount of each of a plurality of measurement regions set in a measurement target, comprising:

• a camera including a two-dimensional imaging device having a partial reading function for reading a part of an imaging region;
• and
• a hardware processor that sets a plurality of the parts, which correspond to partial regions each of which includes two or more of the measurement regions, in the imaging region,
• acquires a photometric quantity of each of the plurality of partial regions corresponding to the plurality of parts by causing the two-dimensional imaging device to image the measurement target multiple times using the partial reading function with the number of set parts as the number of times of imaging, and
• executes processing, which is for calculating flicker amounts of the two or more measurement regions included in the partial region based on the acquired photometric quantity of the partial region, for each of the plurality of partial regions.

A two-dimensional flicker measurement method for measuring a flicker amount of each of a plurality of measurement regions set in a measurement target using a two-dimensional imaging device having a partial reading function for reading a part of an imaging region, the method comprising:
