And the image intensity to be multiplied.
- the conventional fluorescence measurement device multiplies the output signal obtained from the periodically generated fluorescence component by the image intensity. This is because if each fluorescent component is weak, it is difficult to perform accurate measurement with one measurement, so it is necessary to expand the dynamic range of the output signal. Further, the conventional fluorescence measurement device uses a streak camera and sampling means to cope with the non-linear waveform of each fluorescence component. For this reason, there has been a demand for fluorescence measurement to be performed more easily using a CCD (ChargeCooledDevice: charge-coupled device) without using a streak camera.

- a fluorescence measurement device is a fluorescence measurement device that measures a fluorescence component emitted from an object to be measured corresponding to each of excitation pulse components irradiated to the object to be measured. It includes a conversion element, a charge storage element, and a control unit.
- the photoelectric conversion element photoelectrically converts a fluorescent component emitted from the device under test corresponding to each of the excitation pulse components.

If the fluorescence components have substantially the same period, the number of times of generation of fluorescence per predetermined time can be easily specified, and synchronization with the electronic shutter signal can be easily achieved. If the fluorescent components have substantially the same waveform, it is easy to measure the same waveform portion of each fluorescent component.
- the control unit outputs an electronic shutter signal and a readout signal so that the same waveform portion of each of the fluorescent components can be measured. If the same waveform portion of each fluorescent component is measured, the charge corresponding to those portions can be obtained by dividing by the number of measured fluorescent components.

That is, the transfer signal is output periodically during the period T in FIG. 4G. Since this transfer signal is a signal for transferring the charges accumulated in the horizontal transfer elements 101c, the accumulation of unnecessary charges in each horizontal transfer element 101c can be reduced.
