The present technology relates to an image processing apparatus and an image processing method, and particularly to an image processing apparatus and an image processing method capable of suppressing an increase in a load on a subject and obtaining a captured image of the subject with higher image quality.An imaging unit reduces a light amount and performs a plurality of imagings of the fundus of the eye so as to generate a plurality of fundus images. A biological information alignment processing unit aligns the fundus images by using biological information of a subject. A super-resolution processing unit superimposes an aligned input image on a previous super-resolution result image so as to generate a new super-resolution result image. The super-resolution processing unit stores or outputs the super-resolution result image in a storage unit or from an output unit, and supplies the super-resolution result image to a super-resolution result image buffer so as to be stored. The present technology may be applied to, for example, an image processing apparatus.
