  Computational ghost imaging is a promising technique for single-pixel imaging
because it is robust to disturbance and can be operated over broad wavelength
bands, unlike common cameras. However, one disadvantage of this method is that
it has a long calculation time for image reconstruction. In this paper, we have
designed a dedicated calculation circuit that accelerated the process of
computational ghost imaging. We implemented this circuit by using a
field-programmable gate array, which reduced the calculation time for the
circuit compared to a CPU. The dedicated circuit reconstructs images at a frame
rate of 300 Hz.
