1. A laser processing system comprising:
a laser processing device configured to process a processing target in accordance with a processing pattern; and
a verification device configured to verify processing by the laser processing device, wherein
the processing pattern includes a plurality of cells,
the laser processing device includes:
a receiving unit configured to receive the processing pattern;
a setting unit configured to set an irradiation condition of laser light for each of the cells of the processing pattern received by the receiving unit;
a first storage unit configured to store the irradiation condition set by the setting unit for the each of the cells for which the irradiation condition is set; and
an irradiation unit configured to irradiate the processing target with the laser light based on the irradiation condition set by the setting unit,
the setting unit sets, as test cells, a part of the processing pattern received in test processing, and sets different irradiation conditions respectively for the cells included in the test cells,
the verification device includes:
an imaging unit configured to capture an image of the processing pattern formed on the processing target; and
a calculation unit configured to calculate luminance values for the cells respectively based on the image captured by the imaging unit, and
the setting unit sets at least one of the irradiation conditions for main processing, based on information on luminance values of the test cells extracted from the luminance values for the cells and based on the irradiation conditions set for the test cells.
