Imaging device, imaging method, and image processing device

An image processing device comprising:

• an image acquisition circuit that acquires a plurality of successive images of a subject, which are captured through an optical system, from an image sensor;
• a filter acquisition circuit that acquires a restoration filter generated corresponding to a transfer function for point distribution of the optical system;
• a subject distance acquisition circuit that acquires subject distances of the subject in the plurality of successive images which are acquired from the image sensor;
• a movement amount acquisition circuit that acquires an amount of movement of the subject in an optical axis direction of the optical system between the plurality of successive images acquired from the image sensor, on the basis of the subject distances which are acquired by the subject distance acquisition circuit;
• a restoration processing determination circuit that determines whether a restoration processing should be performed on the plurality of successive images through the restoration filter with a general restoration strength, a restoration strength of the restoration processing should be adjusted and the restoration processing should be performed on the plurality of successive images, or the restoration processing should not be performed on the plurality of successive images, on the basis of the amount of movement acquired by the movement amount acquisition circuit;
• a restoration strength adjustment circuit that adjusts the restoration strength of the restoration processing in case where the restoration processing determination circuit determines that the restoration strength of the restoration processing should be adjusted and the restoration processing should be performed on the plurality of successive images;
• and
• a restoration processing execution circuit that performs the restoration processing on the plurality of successive images through the restoration filter with the general restoration strength or with the adjusted restoration strength, on the basis of the determination of the restoration processing determination circuit.
