Abstract
The light measurement device is provided with a moving-image acquisition part and an analysis processing part. The analysis processing part includes: a luminance-value-data acquisition part for acquiring the luminance value data; a luminance-value extraction part for extracting a peak value and a bottom value of the luminance value, from the luminance value data; a pixel extraction part 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 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.
