1. A medical image processing apparatus comprising:
an obtaining unit configured to obtain (1) a plurality of tomographic images obtained by radially scanning measuring light on an eye to be examined, and corresponding to a plurality of locations of the eye to be examined, respectively, and (2) an imaging parameter corresponding to each tomographic image;
a modifying unit configured to modify a shape of a tomographic image corresponding to the imaging parameter by using the imaging parameter;
an aligning unit configured to align a plurality of shape-modified tomographic images with each other;
a data generating unit configured to generate three-dimensional data using the plurality of aligned tomographic images; and
a data integrating unit configured to define a pixel value of a position at which at least two tomographic images among the plurality of aligned tomographic images intersect in a three-dimensional space, using a value obtained by integrating pixel values of the position of the at least two tomographic images,
wherein the data generating unit is configured to generate three-dimensional data using (1) the plurality of aligned tomographic images and (2) the pixel value defined by the data integrating unit.
