According to one embodiment, a binarized threshold value determination device includes, a creating unit, an average gray level value calculation unit, a parameter calculation unit, a correction unit, a selection unit, and a determination unit. The correction unit configures to correct the gray level value of the gray level histogram on the basis of the gray level conversion parameter which is calculated in the parameter calculation unit. The selection unit configures to select a temporary threshold value from the gray level histogram of which the gray level value is corrected in the correction unit. The determination unit configures to determine a threshold value for binarizing each of the pixels by performing an inversion correction with respect to the temporary threshold value which is selected in the selection unit, on the basis of the gray level conversion parameter which is calculated in the parameter calculation unit.
