1. A medical image processing apparatus comprising
an image processor configured to
acquire a first fluorescence image captured between a timing when a first drug is administered and a first timing when a second drug is administered and a fluorescence intensity of a predetermined region starts to increase, and a second fluorescence image captured after the first timing; and
generate an output image in which fluorescence generated by the second drug is enhanced on a basis of the first fluorescence image and the second fluorescence image, wherein
a timing when each of the first drug and the second drug is administered is detected on a basis of a fluorescence image captured, and
the image processor is configured to detect a minimum value of a change in luminance in time series in at least a part of an image after an administration of the second drug, and acquire a fluorescence image captured before a timing when the minimum value is detected as the first fluorescence image.
