Spectral sensitivity measuring device and spectral sensitivity measuring method

A spectral sensitivity measuring device, comprising:

• a first imaging device;
• a chart generation system that includes:
• a light source;
• an optical filter group between the light source and the first imaging device, wherein the optical filter group includes a plurality of optical filters;
• a moving mechanism configured to move the optical filter group, the first imaging device, and the light source such that each of the plurality of optical filters is at a respective sequential position between the first imaging device and the light source;
• a control unit configured to sequentially generate a plurality of charts that corresponds to the plurality of optical filters, wherein
• at least one chart portion of each of the plurality of charts includes a color region,
• the each of the plurality of charts is at a position opposite to a position of the first imaging device, and
• the first imaging device is configured to capture a respective image of the each of the plurality of charts;
• and
• a processing system configured to calculate a spectral sensitivity of the first imaging device based on the respective image of the each of the plurality of charts.
