A light measurement device 1 is the light measurement device 1 for measuring light emitted from a cell. The light measurement device 1 is provided with: a moving-image acquisition part 40 for acquiring moving image data of a two-dimensional light image; and an analysis processing part 51 for performing analysis processing on the moving image data. The analysis processing part 51 includes: a luminance-value-data acquisition part 52a for acquiring the luminance value data; a luminance-value extraction part 52b for extracting a peak value and a bottom value of the luminance value, from the luminance value data; a pixel extraction part 52c for extracting a target pixel configuring an image of a predetermined cell from a plurality of pixels, on the basis of the evaluation value. The pixel extraction part 52c extracts, as the evaluation value, the target pixel on the basis of at least one of an amplitude of the luminance value obtained from a difference between the peak value and the bottom value and a change ratio of the luminance value obtained from a ratio of the peak value relative to the bottom value. |
