1. An image processing apparatus, comprising:
a processor configured to:
obtain first image data of a first image of a blood vessel, wherein the first image is captured by IndoCyanine Green (ICG) fluorescence imaging;
obtain second image data of a second image of the blood vessel, wherein the second image is captured by an application of white light;
calculate, based on a first difference value between the first image and the second image, a correlation value between the first image and the second image;
determine, based on the first image data and the second image data, a first feature that includes the calculated correlation value;
execute a first image process on the first image data at a first intensity;
execute a second image process on the first image data at a second intensity different from the first intensity;
determine a second feature that includes one of a vascular diameter or a second difference value between a result of the first image process and a result of the second image process, wherein the vascular diameter is based on the second difference value; and
control, based on at least one of the first feature or the second feature, a degree of an enhancement process on the first image data.
