1. An image processing apparatus comprising:
one or more processors connected to one or more memories storing instructions executable by the one or more processors, wherein the one or more processors connected to the one or more memories are configured to function as:
an obtaining unit configured to obtain an optical coherence tomography (OCT) image and an OCT angiography (OCTA) image of mutually corresponding regions in a subject that are acquired by an optical interferometer;
a blend processing unit configured to generate a blend image obtained by performing blend processing at a transmissivity changeable in response to an instruction from an operator using the obtained OCT image and an OCTA image of high image quality obtained by inputting the obtained OCTA image as input data of a learned model for image quality improvement obtained by learning an OCTA image of the subject;
a display control unit configured to control the display unit to display the generated blend image on the display unit; and
a selection unit configured to select a type of analysis processing to be performed on the OCTA image of high image quality;
wherein the display control unit controls the display unit to display a result of the selected type of the analysis processing on a region of interest in the OCTA image of high image quality set in response to an instruction from the operator in the displayed blend image.
