A photon counting device includes a plurality of pixels each including a photoelectric conversion element configured to convert input light to charge, and an amplifier configured to amplify the charge converted by the photoelectric conversion element and convert the charge to a voltage, an A/D converter configured to convert the voltage output from the amplifier of each of the plurality of pixels to a digital value and output the digital value, a correction unit configured to correct the digital value output from the A/D converter so that an influence of a variation in a gain and an offset value among the plurality of pixels is curbed, a calculation unit configured to output a summed value obtained by summing the corrected digital values corresponding to at least two pixels, and a conversion unit configured to convert the summed value output from the calculation unit to a number of photons.

Photon counting device and photon counting method

A photon counting device includes a plurality of pixels each including a photoelectric conversion element configured to convert input light to charge, and an amplifier configured to amplify the charge converted by the photoelectric conversion element and convert the charge to a voltage, an A/D converter configured to convert the voltages output from the amplifiers of the plurality of pixels to digital values; and a conversion unit configured to convert the digital value output from the A/D converter to the number of photons by referring to reference data, for each of the plurality of pixels, and the reference data is created based on a gain and an offset value for each of the plurality of pixels.

An image acquisition systemincludes: a light sourcewhich outputs illumination light; an optical scannerwhich scans a sample S with the illumination light; an optical scanner control unit; a detection optical systemwhich focuses fluorescence from the sample S; an imaging devicewhich has a light receiving surfacein which a plurality of pixel rowsare arranged, and an imaging control section, and which can perform signal readout of each of the plurality of pixel rowsfrom the light receiving surface; and a calculation unitwhich calculates an interval of signal readout between adjacent pixel rows, based on a moving speed of an illuminated region on the light receiving surface; the imaging control sectioncontrols signal readout of each pixel row, based on the interval of the signal readout thus calculated.
